Willing to listen to anyone who has a cluestick and is willing to apply it. We use PXE to boot RedHat's kickstart. That installs the OS. It then runs a script. We have a RPM file which contains as dependencies the names of all of the packages we want installed and the second-last step of the kickstart is a yum install ... of that RPM (and all of its dependencies, which is the point). The last step is to run cfengine to update and maintain the configurations. Total takes about 20m from power-on to running across a 1Gbps network. You're not clear what these boxes are and what they are for. If they are for general PC use, then I'd do exactly as we have done. Because then when fielded the machines will be easy to maintain (if you want to add a package, then you add it to the meta-RPM, and the overnight yum update will pull it in; similarly if you want a widespread change of config cfengine can do that fine). I'd probably substitute puppet for cfengine, for no other reason than its newer. Have a look at past lca miniconfs and SAGE-AU conferences. Running up thousands of machines across the university break is a popular uni sysadmin topic. As is the subsequent administration of those machines. If not, then you've got some alternatives: - put the shipping config into RPMs as well, and drive the whole thing from kickstart. - format the disk, then drop the 15GB of data on top (like this: the dev machine create a 15GB partition, create the filesystem, save it using dd. On the target, dd the file into the disk. Use growfs to expand the fileysystem to the end of the 150GB partition.) Now you've copied only 15GB to get your 150GB filesystem. Either way, I'd drive the build from packages. That is one of the big lessons of the OpenWrt project -- packages have benefits for embedded software too (configuration control, etc). -- Glen Turner -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Here's why: Pretty much every distro has some form of automated installation system. Red Hat (and Fedora) have kickstart, Debian has debconf preseeding, while Ubuntu actually has both (it translates from kickstart into preseed, so you can use similar tools to deploy Ubuntu as you use with Red Hat). Once the automated installs are complete, you can execute a configuration management tool such as puppet or cfengine to make local customisations. One obvious use of this is to ensure network settings are correct (and in many cases, unique). A massive advantage of using a configuration management tool is that you can roll out changes to some or all of the machines really easily, based on a centralised change management scheme. The best bit? Next time you do an auto install of a machine, it will be as up to date as all the others, straight away, and you don't have to keep on regenerating a binary image.

Willing to listen to anyone who has a cluestick and is willing to apply it. Building a provisioning infrastructure is the easy part. Managing a deployment of 3000+ machines is going to be a challenge. Are these set-and-forget machines, or are you going to have to change stuff on them in the future? Even if they are set and forget, I can imagine that your requirements *will* change in the future and you'll be up shit creek if you've done just plain imaging. My suggestion (speaking as someone who's done a 400+ seat deployment, twice): - use your distro's network boot + auto install system to install the most miminal of base images you can get. (kickstart, debian-preseed and PXE are your friend) - hook a configuration management system in an the end of the prep process and have it configure the machines (Puppet is perfect for this) Jeff hit the nail on the head when he explained why you need to use a configuration management system. If you don't have that infrastructure in place you're going to hate yourself when you have to change some seemingly trivial setting across 3000+ machines. You'll end up duplicating whatever work you do, because you'll need to check that the change works on existing machines *as well as* new machines that you provision. Put really simply: keep as much logic as you possibly can *out* of your provisioning process and rely on a configuration management system like Puppet.

[SLUG] April SLUG Monthly Meeting — this Friday
You can read the full version of this announcement on the Web at http://www.slug.org.au/node/97 == April SLUG Monthly Meeting == NOTE: Due to a clash with ANZAC Day, the April SLUG meeting has been deferred by one week to 2 May. The official May meeting will not be affected. Also, please note that our originally-scheduled SLUGlets talk has been postponed, given its common subject matter with the In-Depth talk. When: 18.30 - 20.30, Friday, 2 May, 2008 We start at 18:30 but we ask that people arrive 15 minutes early so we can all get into the building and start on time. Please do not arrive before 18:00, as it may hinder business activities for our host! Appropriate signage and directions will be posted on the building. Where: Atlassian[0], 173-185 Sussex Street, Sydney (corner of Sussex and Market Street) Entry is via the rear on Slip Street. There are stairs going down along the outside of building from Sussex St to near the entrance. A map of the area and directions can be found here[1]. = Talks = ** General Talk ** Matthew Palmer: Deploying and Managing large scale Linux deployments ** In-Depth Talk ** Martin Visser: Wireshark — Packet Sniffing Wireshark 101 or how-can-i-figger-out-wot-the-flamin'-network-is-doing! For many system administrators, what happens on the Ethernet and beyond is quite opaque and unfathomable. However, being able to efficient examine the network is a great boon to troubleshoot system issues, understand performance issues, and the like. Developers of network-centric applications should have a good understanding of the impact of their application on the wire. Martin has used Wireshark (formerly known as Ethereal), the packet sniffer and analyser, many times to objectively finger-point at configuration issues and steer sysadmins in the right direction. This talk will show how to use the important features of Wireshark, how it teaches you about networking and how it makes your life better. Martin has been involved in network engineering and consulting for nearly 20 years, working as a Network and Security Consultant with HP in Sydney for 10 years. He has been using Linux since 1992 and have been irregularly attending SLUG meetings since then. = Meeting Schedule = See here[2] for an explanation of the segments. * 18:15 : Open Doors * 18:30 : Announcements, News, Introductions * 18:45 : General Talk (see above) * 19:30 : Intermission * 19:45 : Split into two groups for * In-depth Talk (see above) * SLUGlets: Linux QA and other miscellany * 20:30 : Dinner Dinner is at Golden Harbour Restaurant, in Chinatown.

Except there aren't any :-) My exim4.config has: mailman_director: driver = accept require_files = MAILMAN_HOME/lists/$local_part/config.pck local_part_suffix_optional local_part_suffix = -bounces : -bounces+* : \ -confirm+* : -join : -leave : \ -owner : -request : -admin transport = mailman_transport So I guess what I should have done is just remove MAILMAN_HOME/lists/list-to-delete/config.pck ... ??? But I believe this file is shared with the code that generates the archive stuff. -- Dr Peter Chubb http://www.gelato.unsw.edu.au peterc AT gelato.unsw.edu.au http://www.ertos.nicta.com.au ERTOS within National ICT Australia -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Last time I played with mailman it was on a qmail machine (doubleplus horror), where multiple .qmail files under /var/qmail/something were used for each mailman list eg .qmail-foo-join .qmail-foo-admin etc. Ergo remove them to stop the list working. -- Thanks, .

Re: [SLUG] Ubuntu 8.04 issues - are there any?

Has anyone else had any problems? I'm thinking of upgrading several machines. I upgraded my laptop to 8.04 from 7.10 and don't know if the upgrade left the system at a broken state because of a local fault (I didn't stay to watch it when it failed, and my wife may have drained the battery), special setup (I use LVM) or simply because it's screwed. I ended up re-installing from an image of rc1 and this is what I now have on the laptop (I wanted the upgrade because of Firefox 3 and Evolution which can actually talk to an Exchange server). My desktop shows the upgrade button and starts it but just fails after a long time and gets back to 7.10, so that's where it is right now. A colleague who tried 7.10 because the Vista that he got with his brand new laptop just Didn't Work (TM) was happy with it but when he tried to upgrade nothing worked. I hope I won't loose another Windows-Linux convert because of this. So my conclusion for now - you might be better off waiting a little until the wrinkles are sorted out.

[SLUG] Outputing progress counters with PHP/HTML
I have a need to output a progress counter from a PHP script that takes a while to run whilst writing a large number of records out to an SQL database, mainly so that the user knows that things are still happening and not hung. It seems a simple thing to do, but when I try it, the progress counter (say, every 100 records) instead of being output at the correct time, gets delayed until the whole process has finished. What is the best way to get around this problem. -- Howard LANNet Computing Associates http://lannet.com.au When you want a computer system that works, just choose Linux; When you want a computer system that works, just, choose Microsoft. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

not necessarily the *best* way:
?php
$i = 0;
do {
print hai tharbr /;
flush();
sleep(1);
$i++;
} while ($i 15);
