marclaportehi everyone!
I would like to introduce changi, who will help with server administration 		[16:19]
changi|awayhello all [16:20]
***changi|away is now known as changi [16:20]
ametteheya changi :)
amette just woke up - right in time... ;) 		[16:26]
changihi amette [16:29]
ametteI fear the account validation on sysadm.tw.o doesn't work correctly... marclaporte had problems..
... I tried it now - did you get an e-mail?
otherwise we need to activate your account manually.. 		[16:30]
changino, i don't [16:31]
You've got a mail :) :)
thx, i now have access 		[16:41]
amettegreat, cool :)
then I worked after all ( I was just on the phone and didn't do anything about the login... ;) ) 		[16:52]
changipretty cool [16:53]
ametteok, I put you now in the sysadm-group, so you should see what I wrote so far [16:54]
changiok will see that later [16:54]

just to know, what operating system is running for dev and doc ? 		[18:30]

amettechangi|away: it's Gentoo [18:45]
changi|awayamette: ok, don't know this OS, (i work on debian) but if you need any help just ask [18:47]
amettecool - do you have an SSH-key? So I can give you login to the machines.
then you can look around and become familiar with it 		[18:48]
changi|awayyes have one [18:49]
amettecool, just paste it here or so [18:49]
changi|awayssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA25JRqquGB9ZU5i+rnBgP1D/KS4VqlMc6/OcTSDbg0NLJshKVJgZ3eXo8nR8GVs39l0dcpnBX7BFiqrSWv7Fx62fm58FXl7/htVJ1wjBKvgahqyKpjlXvo5gOsBCNe8PYgsqN8Y3y3B1xd+3WdF7e5N3o5t91kKguFdiR8huDSw1qwDoQL4xzFj5wj2GydXZWLYuBxPxLptIOY7kuFL3M2648mFIn7k23SPrkHK5ss2G5O6s1dDMRVnp17JQBWpfQzf+AlKy8a9y/7C2JaQ896TeMLFXavjvcL+f0TnDBvtGPA+CSLcvPtfrJIY+SJ5T9DqRa/j0O7jCjhLp/oahFKQ== changi@sga [18:50]
ametteok, you should be able to log in to dev/doc and db0.tw.o now...
... db0.tw.o doesn't have a dns-entry, I think...
... 78.46.199.149 it is
thinking of making it a completely private machine... dunno... let's see next year about that 		[18:51]
changi|awayit ask me a password [18:53]
amettehuh? [18:53]
changi|awaydid you put it in authorized ? [18:53]
amettejust pasted it in [18:53]
changi|awaystrange, i use this key to connect to info.two [18:54]
ametteso, yeah
hmmm, tried other hosts? dev/doc? 		[18:54]
changi|awaywhich user should i use ? [18:55]
ametteah, right - root [18:55]
changi|awayit works [18:55]
amettegreat :) [18:55]
changi|awaydon't you think it's a little bit dangerous to put root access direct on the internet :) [18:56]
ametteyes, I do think so :)
there's a private network, which I planned to use for that...
... I haven't done much after putting the machines up.. I have planned that for the next month, after I found a final place to live in... ;) 		[18:56]
changi|awaymarc tell me about that [18:57]
amette... so until then I'm totally open for any good suggestions how to do it.. :)
ah, ok, cool 		[18:57]
changi|awayyou're in berlin ?? [18:58]
ametteyup, just moved here three weeks ago [18:58]
changi|awayok [18:58]
ametteyou're in strasbourg? [18:58]
changi|awayyes [18:58]
ametteok, cool, no problem with timezones then... ;) [18:58]
changi|awayyes it is, [18:59]
ametteso, just have a look around the machines, hang out here and feel free to ask..
.. I'm always online, but not always there - but ping me and I read back my chatlogs! 		[18:59]
changi|awayno problem
just to understand the architecture, it a single machine with xen and 3 or more virtual machine ? 		[19:00]
ametteit is a single machine running Xen, with 3 DomUs
there is one more DomU, which is the management machine - it compiles upgrades, does NIS and NFS
and it runs the nagios in the topic 		[19:01]
changi|awayyes talking about that, the main page of the site is very cool (It Work's)
on which server did nagios run ? 		[19:02]
amettehehehe :P
man.tikiwiki.org
wait, I put your key there, too... 		[19:02]
changi|awaya lot of server :) [19:03]
ametteah, nope, right, I don't have login there...
hehe, yeah, it was planned to make this scalable - so that you rent another server and can duplicate a webserver there and manage it from the same management-server..
... eventually it gets complex... ;) 		[19:03]
changi|awayso who manage the nagios srv ? [19:05]
amette... but I think it's still pretty simple overall - it really just does the necessary (when taking the scalability into account).
currently me - and Avonsys has another one, where we don't have access...
... monitoring of the other tiki-sites should be in this nagios, too...
.. we need some way to coordinate our efforts though.. 		[19:05]
changi|awayIt's a little old version
:) 		[19:07]
ametteehm, yeah - I got login there... just no authorized_keys yet - try now.. ;)
yeah, I didn't want to go to 3 immediately - it was just fresh, when I set that nagios up
but so far there are also no interesting features in 3, that would make the upgrade necessary 		[19:07]
changi|awayI use the nagios3 for 9 month, and it's pretty cool :)
group management and look and feel 		[19:07]
amettenice [19:08]
changi|awayman.two has got no DNS [19:08]
ametteah, ok, that can be... man0.tw.o or 78.46.199.144 or manager.tw.o
I only access it from the hypervisor 		[19:09]
changi|awaynice
gentoo has the same folder structure than debian 		[19:11]
ametteyeah, even a bit stricter to the FHS, why I like it more [19:14]
changi|awayWill be easy to accomodate :) [19:14]
amettethink so :)
I use git in the / directory to track configuration changes...
... there's currently lots uncommitted, when you look at git-status - was a stressy time.. ;) 		[19:14]
changi|awayusing git to track modification. Tricky system :) [19:16]
ametteyeah, I meanwhile think that hg would have been the better choice...
... still gives you all the power of distributing configurations to machines, etc but easier to handle... 		[19:17]
changi|awayhave you heard about puppet ? [19:18]
ametteno, sounds unfamiliar [19:18]
changi|awayhttp://reductivelabs.com/products/puppet
pretty cool system :)
I use it to make DRP on my debian server 		[19:18]
ametteDisaster Recovery? [19:20]
changi|awayYes sir [19:20]
ametteok :) [19:20]
changi|awaybut we will see that later [19:20]
amettesounds like a pretty mighty system - gotta have a look at it :)
yep, right :) 		[19:20]
changi|awayi would like to draw a system architecture of your installation [19:21]
amettethere's also a very nice and lightweight system working on top of rsync, which google uses... don't recall the name..
yeah, sure - I'd love that! :) 		[19:21]
changi|awayI'll start and send it to you to make correction [19:21]
ametteI have a very simple drawing in the slides, where I presented this setup... [19:21]
changi|awayis that ok for you [19:21]
ametteyes, sure
which software do you use for it? 		[19:22]
changi|awaythe software you want [19:22]
ametteheh, ok - as long as it's open source, I'm happy, I guess... ;) [19:22]
changi|awaykiwio, oodraw,
gimp 		[19:22]
ametteI used oodraw out of necessity, to make this quickly: http://conf.phpquebec.com/slides/2009/The-virtualized-server-infrastructure-of-the-TikiWiki-community-phpquebec_2009.pdf
I think some vector oriented would be good?! dia or so? 		[19:23]
changi|awayok for DIA [19:25]
ametteok, cool [19:25]
changi|awayjust to know, is there a possibility to have one of this server on debian or ubuntu OS ? [19:27]
ametteyeah, that would be possible [19:27]
changi|awayok
good 		[19:28]
amettebeen thinking of moving over to Debian afterwards... dunno, if others like to maintain Gentoo systems... but for now I like Gentoo because of it's flexibility, I can play very freely with what I want to do [19:28]
changi|awaywe could discuss of what you need and I think all your doing with Gentoo is possible with a light debian :) [19:29]
ametteyeah, I think so, too - but on debian I would have already installed a complete X ;)
not necessary here - I like that :) 		[19:30]
changi|awayOn my point of view, X is not necessary
Why would you installed a complete X ? 		[19:30]
ametteyeah, it shouldn't be - but it's very often a dependency, when you install a server with debian - on Gentoo, I just set the USE-flag to "-X" and it doesn't do that part [19:31]
changi|awayto help for configuration ?
I manage over 30 linux debian with plainty of software ( apache, mysql, nagios, cacti, .... and more) with no X dependency :) 		[19:31]
ametteI used Debian in my former job and it was nice and easy to work with it in a team, but sometimes I missed my Gentoo flexibility ;) [19:32]
changi|awaylol [19:32]
ametteoh, with cacti I would have expected the dependency of rrdtool and that rrdtool would pull in Xlibs, which then pull in the complete X-libraries... ;)
I gotta run to the grocery store... bbl 		[19:33]
changi|awayyou're right libX11 :)
but it's just client side
:) 		[19:35]
amettehehe, well... fair enough.. ;) [19:37]
changi|awaydo you know screen ? [19:40]
