If you absolutely have to use a relative path (which you won't) make certain that your current working directory is the one that you wish to be in and force the script to fail if it's not. Imagine running: rm * From your home directory instead of some temporary directory because your script couldn't change into it. That being said: #!/bin/bash basepath="/some/path" if [ -d $basepath ]; then cp -rv $basepath/captures/*.* $basepath/20091230\ Radio\ meteor\ obs\ captures\ test/ && cp -rv $basepath/wav/*.* $basepath/20091230\ Radio\ meteor\ obs\ captures\ test/wav/ && rm -vf $basepath/captures/*.* && rm -vf $basepath/captures/wav/*.* && fi That should do what you want, but I make absolutely no guarantees (and it's late so my brain could possibly not be working correctly). There are certainly different and arguably better ways of doing it, but that's the most direct translation that I could come up with. Of course you could do more checking to make sure that each of the individual sub directories exist before processing them. As for running it from inside of Dolphin, try opening up Dolphin and right clicking in the window. There is an option to add a link to a script or something executable. And before I forget....drop the spaces in the directories (and files in general if you have them). That's a very Windows way of doing things. But, then again, I'm some what anally retentive about things like that so my viewpoint could be somewhat offset from the norm.

Reading through Erick's script, it certainly does seem solid, and seems to do exactly what your original batch script did, with the except of that directory sanity check.

Most unix commands take multiple strings as arguments, assuming that any space delimits an argument, unless you tell it otherwise with quotes. Thus the following command: bash arg1 arg2 arg3 has three arguments, while bash "arg1 arg2 arg3" has only one argument containing a string with 3 spaces in it. BTW, DOS and WINDOWS usually work much the same way, though with much less consistency and fewer options. If you type: cd Program Files it tells bash to change to two separate directories (impossible), and will complain that there is no such directory as "Program". So you need to quote the space in one of several ways: cd Program\ Files cd "Program Files" cd 'Program Files' Double quotes will allow inserting environment variables like cd "$basepath" while cd '$basepath' would take the $ literally and try to find a directory named $basepath (which even if you could do on some given filesystem, I would not advise, as it is a recipe for confusion). Unix gurus usually try to keep filenames in lowercase and without spaces so command completion (TAB key in bash) and such are easier. Not a hard rule, just a convention-- and Unix will usually do what you need. and as Perl hackers often say: There's More Than One Way To Do It (tm). Or TMTOWTDI for short. :-) It applies to bash scripting as well. -- Matt Warnock RidgeCrest Herbals, Inc.

Evaluation is done in fixed-width integers with no check for overflow, though division by 0 is trapped and flagged as an error.

So > what does it mean that "2" CPUs are detected? Some Pentium 4's (Northwood core and newer) have a technology called "Hyper-threading", a type of simultaneous multithreading (older Willamette P4s did not have them). It's one core, but it appears to the OS as two logical CPUs. It can speed things up by kinda running two threads at the same time, but if both threads want 100% cpu, you'll see poor performance because, well, there's only one real CPU. http://en.wikipedia.org/wiki/Hyper-threading http://en.wikipedia.org/wiki/Simultaneous_multithreading Personally, I hated hyper-threading when I had my P4, but I left it on anyway. -------------- next part -------------- A non-text attachment was scrubbed...

If companies start going out of business because they misused GPL'd code (probably out of ignorance, even), other companies would start getting jittery about using any open source software. Policies will be put into place making it impossible for knowledgeable engineers to incorporate Free Software into their companies' solutions. Free Software would lose out on plethoras of users and the prices of everyday electronics products would go up. Everybody loses.

Agreed. The very best outcome is that they simply comply with the GPL, and perhaps pay a little in damages so there's an incentive to comply from the outset, rather than waiting until they've been forced. Enough to make them wish they'd complied to begin with, but not so much it dissuades them from using the code. -- Shawn From mike.thomas.heath at gmail.com Thu Jan 7 09:21:40 2010 From: mike.thomas.heath at gmail.com (Michael Heath) Date: Thu Jan 7 09:22:08 2010 Subject: [sllug-members]: [sllug-members] GPL lawsuits In-Reply-To: References: <2f932a4a0912151858u41c363e4s5cee6241a67016fa@mail.gmail.com> Message-ID: <2e84de771001070821u18b47570nd4c884eef36a69af@mail.gmail.com> On Wed, Jan 6, 2010 at 5:24 PM, Christian Horne wrote: > lol i hope they go out of buisness for it :) not likely, but if you > don't hope, nothing will happen. or, nothing will seem to.

If I steal from you, society suggests you should seek all legal measures for compensation. If you steal from me, it isn't hypocrisy for me to seek the same redress; it is called justice. You might ask for FLOSS copyright owners to be more merciful when people violate their legal rights, but it is incorrect to call them hypocrites.

The idea behind this mailing list is to simplify the announcements that UTOS provides to the community. While we do a fair bit on our blog, we'd like to keep the mailngs going, but it has become complex to send mail to each Local User Group (LUG) every time we need to advertise an event or announce something. In addition, sending mail to more and more LUGs will make it difficult as we grow the free and open source community in Utah and the Mountain West. Therefore, we are going to be moving all of our announcements and news to the official Utah Open Source "announce" mailing list. It is easy to sign up for this list, just visit our mailing list page and add yourself. Here's the link: http://mail.utos.org/mailman/listinfo/announce There will be a few announcements for this list sent to the individual LUG mailing lists. I also suspect that every so often there will be reminders for those who are new to the community. Beyond that, we plan to send email just to the UTOS announce list. Please feel free to invite your fellow nerds and those you think might benefit from activities that we promote.

But how can you steal something that is both Free as in beer and Freedom, supposedly? I just find it interesting how vocal the FSF / GNU crowd is about how important protecting 'freedom' is, yet their licensing and attitude is tight compared to something like the MIT license. From richard-lists at esplins.org Fri Jan 8 10:10:12 2010 From: richard-lists at esplins.org (Richard Esplin) Date: Fri Jan 8 10:10:16 2010 Subject: [sllug-members]: [sllug-members] GPL lawsuits Message-ID: <201001081010.12561.richard-lists@esplins.org> There are lots of ways to steal freedom. Anything that subverts the will of those who sacrificed to produce the freedom is in effect a theft of that freedom. When an engineer spends his or her time to produce code under the GPL, he or she does it with an understanding that society will enforce the freedom the engineer grants to the users of that code. The engineer makes a decision that it is worth distributing that code because of the share-alike clause in the license (otherwise the engineer would presumably choose a different license). When you violate that license, you have not only violated the rights of the engineer but you have also stolen the freedom that the engineer intended to grant to all future users. When an engineer chooses a liberal license that does not have the share-alike provision, the engineer does not have the same expectation. The engineer understands that you will likely use that code for your own purposes and not contribute back. There are lots of reasons why an engineer would choose such a license. Maximizing societal freedom is not one of them. The Free Software crowd sees GPL violations in a similar way to those who try to subvert a democracy. Someone paid for this freedom that we all enjoy. Subverting that freedom is not only selfish, it is also disrespectful of the sacrifices that were required to purchased it. It should not be surprising that it takes sacrifices and discipline to win freedom. If the FSF / GNU crowd where not vocal and proactive, such freedoms would not exist.

It's just a matter of different definitions of Freedom (which is an *extremely* complex and nuanced concept) or, perhaps more to the point, a different perspective on _who_ is free and how much. The MIT license provides maximum freedom for developers at the expense of downstream users and developers. The GPL ensures that downstream users and developers have exactly the same rights as upstream, at the expense of reducing those rights a little. -- Shawn From blendmaster1024 at gmail.com Mon Jan 11 09:02:04 2010 From: blendmaster1024 at gmail.com (Christian Horne) Date: Mon Jan 11 09:02:15 2010 Subject: [sllug-members]: [sllug-members] GPL lawsuits In-Reply-To: <773c89341001081055y1b96f46et33bfe9c2eb926bd3@mail.gmail.com> References: <2e84de771001070821u18b47570nd4c884eef36a69af@mail.gmail.com> <201001071519.23800.richard-lists@esplins.org> <2e84de771001072351h5eec00dw9e9d979fcd312c1b@mail.gmail.com> <773c89341001081055y1b96f46et33bfe9c2eb926bd3@mail.gmail.com> Message-ID: "how can you steal something..." ...you can't. you can't even "steal" digital music. it's the rights (or marketability, in the case of music) that is stolen.

In my opinion, the best Source Control Management (SCM) system out right now. I've been using it for nigh on a year and I have converted a few systems over to it from svn. This is more of a work session than a presentation, so come on down and learn how to use git. It is recommended that you bring your laptops with you as that will benefit more if you do. Some suggested topics I can cover: - Local and remote git repositories (different workflows and other fun stuff) - Using git-svn to 'convert' from svn - Comparing Distributed Revision Control with Traditional (non-distributed) Revision Control - Git hooks, why they are valuable and when to use them - Other basic git discussions See you all there.

Generally I discourage non-firewall servers from having a real public interface. That is what a DMZ is for. However, I understand that is not always possible. In this case, I would name the internal IP address the name of the server, and the external address the name of the service(s) it provides.

Continuous integration servers are a valuable tool in any shop that develops software. From their site (http://hudson-ci.org/): "Hudson monitors executions of repeated jobs, such as building a software project or jobs run by cron. Among those things, current Hudson focuses on the following two jobs: Building/testing software projects continuously, just like CruiseControl or DamageControl. In a nutshell, Hudson provides an easy-to-use so-called continuous integration system, making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. The automated, continuous build increases the productivity. Monitoring executions of externally-run jobs, such as cron jobs and procmail jobs, even those that are run on a remote machine. For example, with cron, all you receive is regular e-mails that capture the output, and it is up to you to look at them diligently and notice when it broke. Hudson keeps those outputs and makes it easy for you to notice when something is wrong."

Example: server01.tld IN A 192.168.0.5 www.server01.tld IN A 222.222.222.5 server02.tld IN A 192.168.0.6 mail.server02.tld IN A 222.222.222.6 etc. (substituting .tld with .com, .org, or whatever top level domain the server uses) I ask because I like to do websites without the www in front of the domain name, and on my home server, I have done something like this to my home server: server1.domain.mhn IN A 192.168.1.2 server1.domain.tld IN A 222.222.222.2 www.domain.tld IN CNAME server1.domain.tld and if I were to add another server for other services, I might, following the same convention do something like this: server2.domain.mhn IN A 192.168.1.3 server2.domain.tld IN A 222.222.222.3 mail.domain.tld IN CNAME server2.domain.tld Since mhn ('my home network') isn't a true tld, it is only recognized inside my home network. For a business internal network it could be .intra or something else. For the host name I currently do this: 192.168.1.2 server1.mhn server1 I skip the domain on the private side and just go to the server name. Perhaps it should be: 192.168.1.2 server1.domain.mhn server1.mhn server1 If I follow Lonnie's recommended naming convention of private side interface using the host name? Any other recommendations or ideas for a good best practice for naming conventions for multiple homed hosts?

Bind will auto append the domain to all non-qualified names. But if you were to use FQDNs it would look more like this: domain.com. IN A 222.222.222.3 domain.com. IN MX 10 mail.domain.com. server01.domain.com. IN A 192.168.0.2 mail.domain.com. IN A 222.222.222.2 smtp.domain.com. IN A 222.222.222.2 pop3.domain.com. IN CNAME mail.domain.com. server02.domain.com. IN A 192.168.0.3 www.domain.com. IN A 222.222.222.3 As you can tell even more obviously here. The world accesses all of your domains resources using service based names. mail.domain.com, pop3.domain.com, www.domain.com, etc. and your actual server hostnames resolve to internal addresses. Don't CNAME public names to your internal hostnames, cause they won't work (unless they are for internal dev stuff). But using CNAMEs to other public names are perfectly fine. This method avoids any subdomains, keeps all records in one file, and avoids split DNS. It works well with most domains. Unless you have a crappy firewall, internal users will still use the public names as they just use the public addresses.

Use .local * Don't bother with separate domain as that defeats you goal of using one zone file. And implements a more annoying, less usable form of split DNS.

Other common options: * Split DNS - serve different zone files, but the same domain, for internal users or public users. * Separate domain - using a different domain for internal stuff like domain.local Both of these require additional maintenance overhead * subdomains - put all your private names in private.domain.com, and public in domain.com itself if done carefully, you could (though not needed IMHO) prevent public queries of the private subdomain From mwarnock at ridgecrestherbals.com Thu Jan 14 16:25:43 2010 From: mwarnock at ridgecrestherbals.com (Matt Warnock) Date: Thu Jan 14 16:25:50 2010 Subject: [sllug-members]: DNS and Interface Naming Conventions In-Reply-To: <4B4F718B.4080605@mscis.org> References: <4B4CDDF0.8000500@mscis.org> <8bcade371001121416o7b2d1ba3y98abcb161c58cc45@mail.gmail.com> <4B4F718B.4080605@mscis.org> Message-ID: <1263511543.2808.106.camel@matt5.warnocks.org> On Thu, 2010-01-14 at 12:33 -0700, Brandon Stout wrote: > On 01/12/2010 03:16 PM, Lonnie Olson wrote: > > Generally I discourage non-firewall servers from having a real public > > interface. That is what a DMZ is for. As I understand it, the conventional DMZ looks like this: 'Net <--> router <--> DMZ <--> router <--> LAN Where the routers are typically Cisco or other high-end equipment with its own (fairly high) expense and configuration headaches. Over the years of running small Linux networks on static IPs I have developed a practice (perhaps bad) of having a weird "poor man's DMZ", looking more like this: 'Net <--> switch <--> DMZ router/firewall/server <--> switch <--> LAN Usually the DMZ is a single Linux host, serving as router, firewall, and server all rolled into one. (That is where the concept started). More recently, I have a couple of machines so that if one fails, I can easily reconfigure another to take over. These machines are multi-homed, with the LAN on one interface, and the 'Net on the other, so there is a public and a private interface, and Linux doing NAT between the two. Cheap switches are used instead of routers, and the cost is low. All Windows machines are behind a Linux firewall, which has been proved (on many occasions) a Good Thing(TM).

I thought at first that this would mess with e.g. name-based virtualhosting in Apache if you have several domains, but you would always test those with the outside name anyway. Two interfaces, two different names, but one host name.

When you say websites without the "www" it seems like you mean typing "google.com" instead of "www.google.com" and that is done with a separate "@ A 222.222.222.3" record in the zone file. And since you only have one such A record, that one host gets all the traffic, whether HTTP, FTP, SMTP, or other (if only the domain name is given). > and if I were to add another server for other services, I might, > following the same convention do something like this: > > server2.domain.mhn IN A 192.168.1.3 > server2.domain.tld IN A 222.222.222 > mail.domain.tld IN CNAME server2.domain.tld > > Since mhn ('my home network') isn't a true tld, it is only recognized > inside my home network.

In addition, I sometimes use my /etc/hosts as a shortcut to hosts I don't ever want to type out in full: xxx.yyy.zzz.123 my.development.machine.hosted.at.ISP.com dev Any of these will work in /etc/hosts, but the server will assume that the first one is the canonical (FQDN) name, which may break stuff if it is wrong. In particular mail delivery agents are notorious for booting VERY slowly if they can't resolve their own name, and Apache may break too. I tend to just use the main external domain name for hosts in both DMZ and LAN. > Any other recommendations or ideas for a good best practice for naming > conventions for multiple homed hosts? > > Brandon > ______________________________________________________________________ > See http://www.sllug.org/ for latest SLLUG news, information, links. > Join SLLUG and other UT LUG members on irc.FreeNode.net channel #Utah > sllug-members@sllug.org > http://www.sllug.org/cgi-bin/mailman/listinfo/sllug-members -- Matt Warnock RidgeCrest Herbals, Inc.

Generally a DMZ network is completely separate from all networks Internet | | | Firewall ---------- DMZ network | | | Internal/Private network The firewall has 3 interfaces, each on their own network. You then configure the firewall rules like this: allow Internet -> DMZ on select protocols allow DMZ -> Internet allow Internal -> Internet allow Internal -> DMZ This way your private network is protected in case one of your DMZ servers is compromised. Your poor man's DMZ is generally fine, but it doesn't protect your internal machines from attacks if your DMZ computer is compromised. Often (especially in home networks) a real DMZ is overkill. It adds complexity and overhead that is not worth the security added. You just need to evaluate how sensitive your internal machines are, and the probability of compromise.

In the first place, the console is a serial emulation, not a serial port, so the 38400 port speed is meaningless. As usual, "man stty" is your friend. You'll also want to run: stty -a /dev/ttyS0 stty -a /dev/ttyS1 stty -a /dev/ttyS2 and examine the output. If S0 is working and S3 isn't, see what the differences are. I assume you HAVE a physical S3, but that isn't standard on any recent computer I know of. So if you added it, is the hardware working? What do 'dmesg|grep serial' or 'dmesg|grep ttyS[0-4]' tell you? Is the hardware even there? Here is the result of 'dmesg|grep serial' on a desktop machine (my laptop has no serial ports at all). [ 0.808093] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 0.808187] serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A Hmm, using the same interrupts that they always did. This is a blast from the past, I haven't futzed with a serial port in about 10 years. If you don't see ttyS3 in your output, there is your FIRST problem. Once you know the hardware is working, 'stty -a /dev/ttyS3' will tell you the baud rate, data/parity/stop bits (usually 8n1) that the serial port needs to be set to to interoperate with your equipment, whatever it is. You'll also need to set RTS/CTS or XON/XOFF correctly (hardware or software flow control) or you'll lose data. Welcome to the bad old days of serial interface programming. ;-} On Fri, 2010-01-15 at 07:47 -0700, jack b friend wrote: > On Thu, 2010-01-14 at 22:00 -0700, Matt Warnock wrote: > > IIRC, way back in the day, com1&3 shared an interrupt, as did com2&4, > > and on SOME systems, you couldn't use both at once.

I thought I'd just throw in a few suggestions. First, I'm not familiar with that model of radio, but I'm guessing chances are good that you're using a serial-to-USB adapter. If so, you'll want to look through your dmesg history and make sure that the USB stuff assigned it ttyS2. Anything else that is real serial, or other something-to-Serial adapters may have been assigned ttyS2 first. COM port designations, after the physical COM ports, are assigned out on a first come, first serve basis. Particularly if this stopped working after a Ubuntu upgrade, I'd look here first. Second, does Xlog have any device-specific configuration settings? I've never used Xlog, but I have worked with several HAM Radio apps for Linux, and for some odd reason it seems like almost all of them tend to have bizarrely useless and nonsensical default configurations. I don't think I've yet used one where I didn't have to aggressively edit the configuration files just to get it to properly link with the transceiver. Does Xlog have an option to give you more verbose error information?

Vaughan-Nichols: The best Linux file system of all? http://blogs.computerworld.com/15413/the_best_linux_file_system_of_all Among other things, it notes: >> EXT4 is a very fast file system, and it supports file systems of >> up to 1 EB (exabyte) and up to 16 TB (terabyte)-sized files. 1EX = 10**18 bytes (3 orders of magnitude below Sun's ZFS, where 1 zettabyte = 10**21 bytes, but still huge by today's standards). Both EXT3/EXT4 and ZFS have journaling. ZFS supports single files up to 16EB, and importantly, storage pools and snapshots. EXT4 apparently does not: http://en.wikipedia.org/wiki/EXT4 That is a great shame, because both pools and snapshots are fantastically useful. We've been using them for a couple of years now on Solaris in production mode, and for at least two years earlier in test mode. You can get ZFS on Solaris, NetBSD, and FreeBSD. Apple initially announced plans to support it in Mac OS X 10.5, but that did not happen, and they apparently aren't saying why: see http://en.wikipedia.org/wiki/ZFS ZFS on Fuse may be available for Linux here: http://zfs-fuse.net/ ------------------------------------------------------------------------------- - Nelson H.

Just to be clear, ext* doesn't support snapshots because those are handled by the underlying logical block device (If you are using LVM, and why wouldn't you?). And if you want to compare (planned) features against ZFS, compare Btrfs: http://btrfs.wiki.kernel.org/ http://en.wikipedia.org/wiki/Btrfs I read online that ext4 is considered by some to be a transition step from ext3 to Btrfs.

True, but there's a lot of value to doing that stuff in the filesystem, primarily because the filesystem has important knowledge that the block device does not: Which blocks are actually being used. When you go to modify the RAID or pooling structure, this has significant performance implications. Of course, there's also a lot of value in separating volume management from the file system. Which approach makes more sense depends on exactly what you want to do. Like anything else, it's a tradeoff. -- Shawn From marc at sllug.org Mon Jan 18 09:57:36 2010 From: marc at sllug.org (Marc Christensen) Date: Mon Jan 18 09:57:40 2010 Subject: [sllug-members]: SLLUG meeting reminder - this Wednesday!

However, I don't agree with the notion that LVM snapshots are all that comparable to zfs snapshots. Furthermore, to suggest that you could substatute the one for the other just seems misleading and a recipe to set people up for dissapointment. LVM snapshots are really designed only to be kept around temporarily. If you are keeping LVM snapshots alive for any longer than the time needed to operate on the snapshot, you are most likely misusing the snapshot. When you create a LVM snapshot, the volume goes into a degraded state. The performance is greatly reduced until the snapshot is destroyed. Furthermore, the only way to really make sure new data is safe is either by allocating as much space for the snapshot as there is for the volume, or knowing exactly who or what is writing to the volume and knowing that it will never exceed the amount of space allocated to the snapshot. What does this mean? More than one snapshot is impractical for any period of time, and while it is alive, the real volume will have performance issues. Therefore, LVM snapshots are for temporarily freezing the data at a point in time. Without getting technical about the the inner workings and space saving abilities of snapshots and how they actually work. I think the function that most people are looking for when they think of snapshots is multiple incremental history of a file system over time. ZFS, as I understand, is designed to do this out of the box. Because of the implementation of LVM snapshots, it can't practically do this. If ZFS where in the Linux kernel right now, I would probably be using it. Instead I use reserfs v3 and the snapshot feature with LVM. But I use the LVM snapshot the way LVM snapshots where designed to be used. By creating a snapshot copying the snapshot or data from the snapshot then destroying the snapshot. The LVM snapshot most usefully ensures the files are in a consistent state so they can be safely copied. Using rdiff-backup as a copy program to make nightly incremental backups I have revisions that go back a full year. Running a copy program from a snapshot works much better then trying to copy files from a live system as many files from a live system may be in a state of change or are sockets and devices and can cause real issues when they are accessed or copied from a live system. Unlike LVM, ZFS is designed to be able to safely take unlimited snapshots of a file system. This allows the snapshots to be used as incremental file system history. Because the snapshots are almost instant and don't require a complete mirror, they can be made very frequently and require much less space than incremental backups. It will be a big moment for Linux when ZFS is included in the kernel. For the average workstation it would quickly become the default FS. However, rdiff-backup makes actual backups and is more of a solution by its self. ZFS snapshots are confined to the same storage array, and really can only be counted on as file system history and should not be mistaken for a complete backup system. I personally would use reiser4 over zfs if they both wound up in the kernel tomorrow. However, that's only because I already have a system for managing backups and snapshots that I like. If reiser4 had ZFS style snapshots (that didn't degrade what it already is) I think the advantages of Reiser4 would far out way those of ZFS. But until then, I see this as a war between the two FS, and everything else is pretty much obsolete.

LVM snapshots do degrade performance on the original volume. However I would probably disagree with the extent you seemed to describe it. Then you describe ZFS as using a completely different system for making snapshots. This is wrong. ZFS uses the same idea, copy-on-write. The same idea that degrades your system slightly. Also, if you are going to complain about the slight degradation of an LVM snapshot, then ZFS should be absolutely abhorrent to you. ZFS has even more overhead than a simple copy-on-write metadata problem. ZFS also has tons more overhead, especially with the end-to-end checksumming. Now I don't hate ZFS at all. In fact I love it. I use it in production at my place of work. The features you get from it, as well as the combination RAID, LVM, and FS in one, is just plain beautiful. I could go on for hours about the wonders and ease that ZFS has given me. But the fact remains, ZFS requires more horsepower to run than a typical RAID + LVM + FS, but it is very much worth it. --lonnie From aaron.toponce at gmail.com Tue Jan 19 19:17:42 2010 From: aaron.toponce at gmail.com (Aaron Toponce) Date: Tue Jan 19 19:17:57 2010 Subject: [sllug-members]: [sllug-members] news story on EXT4 filesystem In-Reply-To: <8bcade371001190911r62694d57i19511fad2f1b682e@mail.gmail.com> References: <847993121001151718n76df4619l8aba9c468087aa79@mail.gmail.com> <8bcade371001190911r62694d57i19511fad2f1b682e@mail.gmail.com> Message-ID: <4B5667C6.6040509@gmail.com> On 1/19/2010 10:11 AM, Lonnie Olson wrote: > Also, if you are going to complain about the slight degradation of an > LVM snapshot, then ZFS should be absolutely abhorrent to you.

We have three production machines that have ZFS as the underlying volume management/filesystem. While I like the complexity of the tool, and the simplicity of the commands, ZFS is very sluggish. We use iozone and Bonnie++ for benchmarking our disks before deciding whether or not Oracle gets installed, and LVM with ext3 has always outperformed ZFS in every test. Even simple things, like installing software packages, are noticeably faster on RHEL than on Solaris, due to Solaris taking a ZFS snapshot everytime we install something. ZFS might be sexy to some, maybe even critical, but for us, we'd rather not. The time it takes to get things done is just too slow for our patience. -- . O . O . O . . O O . . . O . . . O . O O O .

Message-ID: <20100120054757.GR1611@gnu.prunk.si> I'd like to share with you an experience I just had with my transparent proxy server. I'm sure you're all smarter than me and configure squid to listen to a port other than 3128. If you're not, read along and consider mending your ways. Months ago I reconfigured my SSH server to not listen to its default port because of the obnoxious brute-force hammering I was getting from hosts in the far east. After making that change, I didn't consider that other services running on my box would be of interest to foreigners. Over the past two weeks, I've found that Google has been intermittently been CAPTCHAing members of my family when using my computer at home. It gives a message to the effect of: "We're sorry...but we're getting too many requests from your computer, and want to make sure you're not malware" [0] I wondered what could be the cause, but could not think of anything I've changed on my computer to cause that problem. Fast forward to today, when I was catching up on my emails. I saw some messages from the full-disclosure list indicating that Mandriva has updated their Wireshark package to mitigate some vulnerabilities. I checked the version I had installed on my box, and sure enough, it was vulnerable. After a quick # emerge --oneshot --ask --verbose wireshark I was on my way. One of the emerge messages told me that a new group 'wireshark' was created on my system, and that members of that group could run Wireshark without sudo. That was one of my gripes about Wireshark, so naturally I had to try it out. It worked fine, except I noticed a lot of HTTP traffic to weird sites I've never visited before. Closer inspection revealed that a lot of the traffic was aimed at my port 3128. I brought down squid and watched # netstat -Wtpee and sure enough, the traffic began to dwindle. I ran some of the IP addresses through whois, and, as expected, most were Chinese hosts. Now, I'm about as sympathetic to their plight as they come, and don't mind them bouncing their browsing off my box, but could folks at least have the decency to ask first? I updated and ran rkhunter to make sure there weren't any obvious surprises for later. I then googled around, trying to find out how everybody in Shanghai knew I was running a proxy. I had been a part of the Iran proxy thing in July/August, and wondered if that list was being used by the Chinese, but I couldn't find any hits referring to my dynamic hostname. I then googled my IP address, and found a few blogs that post open proxies [1][2][3]. So it wasn't a leak from Austin Heap's project, but most likely a script that just happen to try the door and find it unlocked. That lead me to wonder when this all started. I went through my old squid access.logs and saw that they steadily grew in size around Christmas. In total, I was treated to over 1G in new log entries. (I wonder what would happen if Beijing tried to subpoena that? DELETED!) The earliest entry in an old access.log that didn't originate from local host was this: 1261657504.667 484 74.XXX.XXX.XXX TCP_MISS/200 1110 GET http://www.seektwo.com/proxyheader.php - DIRECT/75.XXX.XXX.XXX text/html The first field is a timestamp that translates to Thu Dec 24 05:25:04 2009! It's been going on for almost a month! That URL, incidentally, points to a handy webpage that indicates whether you're browser is going through a proxy server. If you google CS_ProxyJudge, you'll find many other sites that offer this /service/. Now, I realize that this is my own fault, and I take full responsibility for leaving my proxy listening on the default port. I've now tightened up my ACL in squid.config so everybody is getting the ACCESS DENIED 404 LOLz :P now. My connection already feels snappier. I'm sure that my ISP will probably feel that this change is comcastic. Today, I learned to never leave services like squid running on the default port without solid ACLs or firewall rules to keep the leechers out.

I don't recall it as it was several years ago when I last set up a squid system. Basically it's part of the standard security install that is used to allow connections to squid. If squid is used in the "hidden" format then it's easy to set up access through iptables. That has been the preferred method when I was setting up squid often. Basically the squid server is inside the firewall and the firewall redirects port 80 to the squid server except port 80 _from_ the squid squid server. Inbound port 80 is dropped at the firewall. Yes leeches are a problem. Often a smart kid will set up a squid proxy to bypass the school filters. Very easy and effective.

That's not what he meant. Your firewall should block incoming connections from the outside world on squid's port. Not incoming connections from your internal network. Also, I have to chime in and agree with Shawn about changing the default port. This practice is never a good solution. It is *not* real security. Adjusting your ACLs in Squid to modify who is allowed to proxy *is* real security. Using a firewall to block incoming traffic from the outside isn't a bad idea either, but your ACLs might be plenty. Interesting story: I had a very similar problem a few years back. I worked at an ISP with plenty of bandwidth to spare. I had my own colocated server. I strongly support the EFF, privacy, etc. Connect all these together and you might guess what I did. I decided to run my own TOR node. Fast forward a month or so, I get a fax on my desk from the FBI, a subpoena for information about a customer in a kiddie porn case. It's my job to track down the customer using the logs. I love this job. I get to help catch the real baddies. A quick lookup in the database, and what did I find? it was ME! me? How could this be? I'm not a kiddie porn user. That's when I quickly realized that it was my Tor Exit node that allowed this. I immediately shut it down, and contacted the FBI agent and explained the situation and apologized that there are no logs, or other ways to identify who the real culprit was. Moral of the story: Think about the possible ramifications of all you do. Even altruistic deeds can be taken advantage of by bad people.

How does dropping > incoming connections *except* for those on squid's port prevent this > from happening? Shouldn't I do something to guard that port instead? It's to prevent an infinite loop. The way he is using SQUID is in "transparent proxy" mode. Meaning there is no config on the internal machines. They think they're talking to the real server on port 80, but your firewall redirects those outgoing connections to your SQUID server which then proxies them for you, again on an outgoing connection to port 80. If your firewall redirects ALL outbound requests to port 80 to your SQUID server, then SQUID gets bounced back to itself and you don't ever actually connect to your intended (outside) server. Does that make sense? Transparent proxy mode has the added benefit of making sure your internal users use the proxy, so you can block access and they can't get around it (Useful if you have children/teens in the house). The way I've used SQUID is on a separate machine inside the firewall. I believe that is the way he meant as well. If you're using SQUID on the firewall itself (Which it sounds like you are from your original post), then it's about the same setup, except you're not redirecting the outbound requests to a different machine, just a different port on the "local" machine (The firewall). Either way, it's a good idea to have SQUID (Or any daemon that is intended to only be used by the local network) listening only on the "inside" interface, not all interfaces. -KW From mac at macnewbold.com Wed Jan 20 11:32:26 2010 From: mac at macnewbold.com (Mac Newbold) Date: Wed Jan 20 11:32:29 2010 Subject: [sllug-members]: Secondary DNS In-Reply-To: References: Message-ID: <20100120112903.S91600@mana.codegreene.com> Sorry to revive a two-week old thread, but I was just working with some DNS stuff this week and thought I'd share what I found. NameCheap.com (one of the <$10/year domain name registrars) has always had very good DNS service included for free with their registrations, which I've used happily for a long time. They recently came out with a FreeDNS offering, where you don't even have to transfer your domains to them. They'll let you use it for primary or secondary DNS, and it is quick and easy to set up, and 100% free. (They say in their FAQ's that it is basically a loss-leader in hopes that you'll use them to register domain names.) I've already got several domains on it and am quite happy. Regarding EveryDNS, it turns out they've now been bought by DynDNS, which doesn't do most of the free stuff that EveryDNS used to do, and their rates seem quite expensive to me. Sad :( .

I ran a TOR middle node for a few months. Initially, I ran it, because I supported anonymity, and felt that no ISP or service had the right to track a users behavior online. Further, I found the "underground web", with sites running on tor nodes. It was rather interesting to browse blogs and wikis in this "underground", and see the very coarse political arena that existed. Then I learned of people using TOR for Bittorrent and kiddie porn, and my support as a middle node waned. I didn't like the fact that I was running a server that was helping the bad guys get around the law. I don't support pornography or piracy of any kind, so down the server went. It's been a rough decision. as I still have the strong views of security, privacy and anonymity, but I can't filter what traffic does and does not enter a TOR node (isn't that defeating the purpose anyway?), and ultimately, I don't want to proliferate the "bad" traffic any further. I'll run it as a client, but I won't run it as a service. -- . O . O . O . . O O . . . O . . . O . O O O . O . O O . . O O O O . O . . O O O O .

Assuming there aren't any exploitable bugs in squid that can be used to bypass the ACLs... which there almost certainly aren't, but I prefer to use the firewall so that potential attackers have no way to even tell that squid (or anything else I don't want to make accessible) is even RUNNING. I just checked my configuration, and I have have squid both firewalled from the outside, and configured not to accept external connections. Actually, squid is secured in two ways. First, the server it's running on has three network interfaces, one external and two internal, and squid is configured to listen only on the internal interfaces. It won't even receive packets that come from outside (assuming the firewall allowed them in). Second, it is configured to accept connections only from IP addresses on my subnet. -- Shawn -------------- next part -------------- An HTML attachment was scrubbed...

The latter two are most definitely not for beginners, though. They're very precise, dense and technical, of interest primarily to language lawyers and compiler writers. -- Shawn -------------- next part -------------- An HTML attachment was scrubbed...

It was one that he wrote as a textbook for a class he's teaching, and it reads like a pretty mediocre textbook. My first book on the subject was Sam's Teach Yourself C++ in 24 Hours. It's thick, and it doesn't go into the STL at all, but I thought it did a nice job of explaining both the language and object-oriented programming. If you just need a bare-bones reference, I'd recommend looking at the C++ Pocket Reference (published by O'Reilly, has a chipmunk on the cover). In general, the Pocket Reference books are short, cheap, and the handiest things on my desk. -------------- next part -------------- An HTML attachment was scrubbed...

I don't know what the current state is. Google for "linux user level interrupts". However, I suspect this may be a case of premature optimization. How quickly do you really need to know about the input change? In most cases like this it is adequate -- and much simpler -- to just poll on a timer. If you really do need faster notification than you can get by setting a reasonable poll interval, and if the user-level interrupt code isn't in the kernel (not sure), another option is to write a small kernel-mode driver that hooks the IRQ you're interested in and then have your interrupt handler communicate it to userspace somehow (signal, event, special file...). -- Shawn -------------- next part -------------- An HTML attachment was scrubbed...

I want to replace it with Postscript output to a laser printer. I have written a bash script that creates the Postscript header to preprint the invoice form and mung the text output to print it in all the right places. Now I need to plug it into the CUPS toolchain. The application prints to LPTx: under DOS, which is mapped to a SAMBA spool, which prints to a CUPS spool. Ideally the script would plug in, process the input, spit it out in postscript, and print it to one of the Postscript printers. Anyone know an easy way to plug such a thing into the system? I'm assuming I need to modify mime.types (or local.types) and add the script somewhere that CUPS can access it. Or should I create a separate "invoice" queue? Where do I tell SAMBA or CUPS to use the filter? Any ideas? Google seems surprisingly unhelpful on this obscure issue. -- Matt Warnock RidgeCrest Herbals, Inc.

For example, I may be out on the road and need to access files from a USB hard drive I have, but that hard drive isn't USB powered (which sucks!), it's AC powered. It won't run on USB alone.

As soon as you get near regular power you can recharge it. But it's still going to be heavy. very, very heavy.

Largest (physically, also oldest) is a 300GB 5.25" drive with a big case, fan etc, that could never run on USB power. In between are several older laptop-size drives that take power from 2 USB ports to run (or a wall wart & one USB port). One has a separate USB-to-round power cable like you describe, another has a weird three-way 2-USB-A-to-1-mini-USB cable that pulls power from both USB-A ports to feed the drive through a single mini-USB on the drive. Most recently, the laptop drives use lower power. I have a USB 750GB WD laptop drive (Costco again) that uses no external power, just the single USB. Maybe a new drive is the better solution anyway. I also recently replaced an older laptop's internal drive with a new one. Three times the storage, half the amps, faster drive, and longer battery life as well. Gave that old laptop a new lease on life. You might want to think about that option, too. Finally, you can get pretty big thumb drives now too-- they don't require external power, and if you need to go from one system to another, they work well.

From bms at mscis.org Wed Jan 27 18:15:52 2010 From: bms at mscis.org (Brandon Stout) Date: Wed Jan 27 18:15:59 2010 Subject: [sllug-members]: samba3 PDC with LDAP backend on Debian Message-ID: <4B60E548.9000507@mscis.org> I'm following the steps on this article: http://wiki.debian.org/SambaDcWithLdapBackend I've been able to follow everything up to 'Testing the configuration' (which had a spelling error that I fixed), where it says 'Log back into phpldapadmin and verify that the DomainName record exists below the root'. I see root, and under root I see: cn=admin ou=admins ou=groups ou=machines ou=users I see these because I created them. Nowhere in the article does it specify to create a DomainName record, or what kind of record it should be. Should it have magically appeared on its own? I doubt it, so I'm thinking there's a hole in the article, unless I missed something. Where should the DomainName record be? After that, the article says 'create the following Samba3 Mappings under the groups OU:' How do I create them? If I click ou=groups and under objectClass, click 'Add Value', there's no value called 'Samba3 Mappings'. The closest one, and the only one I found with 3 fields, was SambaGroupMapping. It has a gid and sid field, but not a 'Unix/Windows Name' field, and if I put what you recommended for 'Unix/Windows Name' for 'sambaGroupType', I get this error: LDAP said: Invalid syntax Error number: 0x15 (LDAP_INVALID_SYNTAX) Description: An invalid attribute value was specified. Any recommendations? Hopefully, I can help you improve the documentation and get accomplish what I'm getting paid to do here at the same time (which is set up Samba as a pdc for 6 Windows XP users). One other problem with the article as I see it. It uses the normal plain text config files for everything except ldap, and there it uses the third party phpldapadmin. I think it would be better if it were consistent and just stayed with using the ldap config files as well. I'm pretty much done with everything in the article now, except all the stuff the article says to do with phpldapadmin, steps which are not very clear. Can anyone here fill in on the ldap config steps for setting up a Debian server as a PDC?

FYI the kernel's command line is: > > kernel /boot/vmlinuz-2.6.31.6 root=/dev/sda4 ro If the root filesystem is indeed on sda4, and the kernel panics at boot stating root couldn't be found, either the kernel parameters are incorrect (which doesn't seem to be the case here) or the kernel is missing the driver for that filesystem. So -- are you sure root is on sda4, and are you sure xfs is compiled into the kernel? It's hard to know what's going on without seeing the kernel output during bootup...

I'm 100% sure that /dev/sda4 is a 40gb XFS partition. When grub was installed, it loaded the stage 1.5 xfs module even. And I know that the kernel has XFS support because the first time I compiled it I did miss the XFS items. So I went ahead and manually edited the .config file and set the XFS as true. Then when I recompiled it asked me a couple of other questions about XFS (debug support and what not). I'll try rebooting and writing down the exact error. I've kind of gotten spoiled with screen captures and copy/paste options... :) From jshatch at azza.com Sun Jan 31 20:23:36 2010 From: jshatch at azza.com (Jarom Hatch) Date: Sun Jan 31 20:23:53 2010 Subject: [sllug-members]: cannot mount file system?

I'm going to ask something really strange here, but does the same thing happen if you use a different filesystem, such as ext3/4?

Are you not supposed to have your kernel and other boot supporting files before the 1024 Cyl boundary for Grub to see it? I know that used to be the case, and the error you describe seems to support that. Usually I place a 100MB /boot partition at the very beginning of the drive to avoid such problems.

Obviously Windows is in there somewhere, but on which one? Also -- can you attach menu.lst in its entirety? I am also curious to see if you run into issues when / is formatted ext3 or ext4 (w/ the appropriate driver compiled into the kernel, of course) per Jarom's suggestion. I'll take that curiosity a step further and ask why you chose to use xfs on a 40GB partition in the first place... I can see the benefits of using it on a volume in the order of several TB since, well, it was written to be used on SGI's large storage systems. I don't see the benefits of using it on a smaller volume (esp on a netbook) where the other filesystems work very well. Just wondering... Some people like to put ketchup on their scrambled eggs, while other people think it's gross. I doubt this issue has to do with the 1024 cylinder boundary (and neither does Jarom -- I just saved him an e-mail), but having a separate partition for /boot is a good practice anyway. -------------- next part -------------- A non-text attachment was scrubbed...
