[Hampshire] LUG equipment
I need a willing (or not so willing, I'm not picky) volunteer to look after a box of LUG equipment - mainly printer, firewall, cables. It's just the one box (it's compresssed over the years as things have become obsolete). I'm finally moving out of Hampshire to the big smoke as an opportunity to enter the world of web scale and big data has arisen. Sadly it's also the world of small expensive places to rent so I won't be able to look after it any more I'm afraid. *Freecycle/Freegle is _great_ for disposing of things without resorting to a skip.

[Hampshire] HantsLUG equipment
Is someone able to help look after the LUG equipment as I'm finding it hard to make the meetings sometimes and I'm looking at moving up the M3 even further in a while. We've looked at splitting the equipment in two before: - network bits + printer - more network bits (backup in case the first person can't make it) The main stuff fits into one plastic box - if someone could be caretaker of that it would be a huge help. It's really just Southampton meetings where it's required. Rather short notice I'm afraid - this Saturday is a case in point - I can only stay until early afternoon.

This event gives those advocates an opportunity to introduce their colleagues to Ubuntu, Canonical, Partners, community experts and their fellow IT professionals. Attendees will learn how Ubuntu is being deployed in the UK and discover how they can introduce or extend this technology safely and effectively within their organisation. All are welcome, but if you already count yourself as an Ubuntu user, please drag along a colleague who has yet to see the light! *1pm - Welcome * An introduction to Ubuntu and our community. *1.20 - Ubuntu in action* A selection of case studies of companies using Ubuntu to enhance their business. */Oxford Archaeology/* Chris Puttick, Chief Information Officer, will explain how one of the largest independent archaeology and heritage practices in Europe, with over 400 specialist staff, took the strategic decision to adopt an open source infrastructure with Ubuntu at the heart of it. */Emphony Technologies/* A start-up software company producing engineering project management and workflow tools for decided to deploy Ubuntu as its infrastructure, find out how they got on and their plans for the future. *1.40 - Open Mic* Ubuntu partners and community members (perhaps including you!) tell us how they use Ubuntu in a business context.

[Hampshire] wierd group issue
I've just been banging my head against lurker (mailing list program we use on hantslug) as it had stopped working. I've diagnosed what's wrong, but have very little clue as to _why_. The box runs exim as a mailserver and that runs as the Debian-exim user: $ id Debian-exim uid=102(Debian-exim) gid=102(Debian-exim) groups=102(Debian-exim),105(lurker),106(greylist) After the upgrade and reboot (no nscd installed BTW), we had this lurker issue so I shoved this little naff wrapper around the process: ps -ef /tmp/apb.$$ /usr/bin/id /tmp/apb.$$ strace -f -o /tmp/strace.$$ /usr/bin/lurker-index $@ This shows: * exim and this process running as Debian-exim * id reports uid=102(Debian-exim) gid=102(Debian-exim) ** what on earth happened to the other groups! * strace shows permission denied (see above) How on earth is it dropping those other groups? The only thing I can think of is that exim's use of setgid/setpgid is doing it. I'll certainly admit that reading those manpages can get your head in a twist so I wondered if anyone can shine a light on it?

[Hampshire] web script suggestions
NB: I'm not after starting a my language is better than yours flamewar! I need to write a small web script (basically a simple front end to populating an LDAP database). Normally I'd do this in Perl (and CGI library) because of PHP's pretty horrific security record, however I think it's time I took a fresh look to see what to use for the next N years. I'd like to write it in Ruby if possible, or Python as a second choice (sorry Adam). I don't really want a huge massive framework with all the hassle that involves - really I'm after a use ... library. For example looking at Ruby, there is a CGI library which allows you to perform the usual set/get forms helpers I want. There is also eruby to assist with the templates, however integrating the two seems a bit yucky. Using ERB seems perhaps slightly easier. Rails is just way too much framework for me. I probably want to end up with something similar to: - script which has the controller logic in it and displays one of two templates - template with the form in it - template with the result in it Thanks for any advice/suggestions.

Re: [Hampshire] SPF Best Practice
Nice post from Martin, so in summary: - publishing your SPF records will help others to drop spam claiming to be from you - and _may_ avoid some backscatter (OTOH the servers backscattering are unlikely to use SPF...) - looking up SPF records will help you to avoid some spam - but _never_ assume an SPF validated email is not-spam There is also DomainKeys/DKIM you may wish to look at which seems to have its own set of issues.

With puppet the use of ldap isn't quite so important, however I believe it still makes sense - I don't really want to run puppet on all my machines just to remove access for one user. Another problem I have is one of the most trivial things to do with cfengine: purge old files in a directory tree. Puppet's tidy seems to want Sucks doesn't it :-) TBH I normally move these out of puppet's domain and into a small cronscript (installed via puppet of course).

Re: [Hampshire] [hardware] RAID5 - hardware or software, based?
On Mon, May 18, 2009 at 17:06:54 + (+), Andy Smith wrote: Indeed, unless under very heavy write load I expect software RAID will be fine. To explain this further, if you do a write on RAID-5, you often have to _read_ the disks first - this can add lots of latency. Personally, I do RAID-1 (software or hardware just _not_ fakeraid rubbish) on anything small (e.g. upto 4 disks). Anything big (read expensive), get a decent _battery backed_ hardware controller or an external RAID array with the same. If you do lots of small writes and wait for them to hit disk, this can make a massive difference (I've personally seen a box go from 100% IO bound to 1% IO when we discovered that the server had been shipped with battery backed RAID controller, but in write though not write back mode). Oddly enough the database went just a tad quicker. Regarding enterprise disks, I think it's mostly a completely fallacy reliability wise. Performance wise, a 15Krpm drive will out perform a 5400rpm drive. However there is another issue - how hard a disk will try and recover data. Western Digital RE (RAID Edition) drives give up quite early - they assume you are running in a RAID (not RAID-0) environment, so if they have trouble reading something, they give up quickly and carry on. Most desktop drives try _really_ hard (and don't give up) - thus they effectively lock up for a few mins upon encountering an error.

One thing I've not seen that much comment on is ease of use and management (i.e you want to change settings etc).

If you want to be ahead of the game, choose KVM. If you have old boxes without hardware support (check BIOS) then Xen's paravirtualisation could be helpful in terms of performance.

I'v used xen both at work and home and generally I've been happy with it. However Xen (host) is stuck at 2.6.18 and recently that's become a big problem (driver support at home, getting occasional spontaneous reboots at work). VMware Server, Virtualbox work the same way - slowly (well, not too bad TBH). ESX and ESXi are better, but they aren't paravirtualised, though there are some drivers for it. KVM can be paravirtualised and everyone is starting to use it.

So I've setup half a dozen OS (dapper, etch, rhel4 and solaris 10) on this over the last week - all worked fine, some are paravirtualised. I've also moved my 6 Xen domains at home over to KVM, also fine, all paravirtualised. Whilst I'm confident that KVM is the way of the future (ubuntu, redhat (which have bought the developes of KVM)), the management tools are very rough and immature ATM. virt-manager GUI is almost useless. There are various gotchas - e.g. using libvirt to manage the domains, without adding featureacpi//feature to the libvirt XML file a graceful shutdown wasn't (it just forced machine straight off). I found KVM networking very easy actually - it's just network bridging. However one thing I miss from Xen is the ability to passthrough PCI cards to underlying domains (this is being added to KVM but may depend upon quite rare hardware support).

If you have ever studied the SAP memory management system you can see why. The general argument goes that 20G of swap is considerably cheaper than having your multi-million pound business down for half a day whilst an admin (or expensive external consultant) debugs a memory issue. Paging in 20GB of swap means your system performance is already going to be pants. Or dead. I'm all for nor falling over since you are a _little_ tight on memory, but really if you manage to undercut it by 20GB you are in serious trouble anyway :-) My issue was that (as I understood it), SAP would _not support_ it unless we had such a ridiculous amount of swap setup.
