studprogHi ... i don't know if this is the right channel - but a request in #ubuntu came out silent.... I'm looking for some help about preseeding an Ubuntu Dapper installation ...02:08
=== whaq|away is now known as whaq
studproganybody here gurus in debian-installer preseeding syntax02:09
lionelpHi studprog02:10
studproghi ;-)02:10
lionelpnever tried myself, but there was a good article on the subject here : http://www.debian-administration.org/articles/39402:10
studproglionelp: yep ... i have noticed it -- but debconf-get-selections --installer came out with the following err :debconf: DbDriver "di_questions": could not open /var/log/installer/cdebconf/questions.dat02:12
lionelpstudprog: you should sudo debconf-...02:13
studprogand just running debconf-get-selections just posts all components set with "select"  as option ...02:13
studproglionelp: i did02:13
lionelpstrange, it works here...02:15
studprogthe folder /var/log/installer/cdebconf does not exsist ---i think it is removed by the installer afterwards (there was a security issue previously about the fact that the root password was readable in the questions file after installation))02:15
studproglionelp: you run dapper ? - or have you upgraded from e.g. breezy02:15
lionelpdapper02:16
lionelpI can check on an upgraded breezy02:16
studprogok ...thats odd ... i'm running a newly installed dapper - and there is no cdebconf dir ... only 3 files - partman, syslog and version02:17
lionelpIt also works on an upgraded breezy02:17
lionelphum... you are right !02:18
lionelp(it was not a stable dapper when it was installed on my desktop)02:18
studprogahh...02:18
studprogso all i have from the installer files is logging by something called Ubiquity02:19
=== lionelp stupid
studproganyways ... what i really would like was to have some command in the preseed file that would let me know that the file actually was read..02:20
lionelpstudprog: with Ubiquity, be do not run Debian Installer02:20
lionelpso...02:20
lionelp:)02:20
studprog??02:21
lionelpUbiquity is not debian installer02:21
lionelpIf you want to have preseed from debian installer, i think you should install with the alternate cd (which installs with Debian Installer)02:22
studprogahh ... i though Ubiquity was some sort of logger .... so it's an installer ?? .... all pages i've seen state that ubuntu either uses debian-installer syntax or something called Kickstart...02:22
lionelpyes, it is the new graphical installer run from the desktop-cd02:23
studprogok -- but i'm installing via PXE -- and i get the text-based installer ... is that d-i or does ubi* also have a textmode ?02:24
lionelpd-i02:29
lionelpubi is graphical02:29
studprogok -- so i should focus on finding the right commands for d-i02:29
lionelpI am not sure I understand what you mean02:30

studproglionelp: well -- i'll go browse the web for some example preseed files (using the d-i syntax) then02:45

lionelpHi screeb03:58
studproghmm ... now it seems that i got past the language selection -- but i've also noticed that my preseed file isn't read ... i use the following parameter to invoke the preseed : preseed/url=http://installserver/preseed -- but from the accesslogs i can see that it's never read during install ;-//03:58
lionelpe-mith is a Linux distribution, I do not understand your will to package. package what ?03:59

porkpienihilocrat:lshw doesn't work06:09
nihilocratRies: is XFS worth checking out for a LAMP server?06:09
nihilocrat'doesn't work' as in it doesn't exist or as in it doesn't tell you anything about the cdrom?06:10
Riesnihilocrat: I didn't select LAMP from the installation menu...06:10
ivoksporkpie: try modprobe sym53c8xx06:10
nihilocratI didn't either, i'm just saying06:10
ivoksporkpie: and sym53c41606:10
nihilocratA server whose purpose is a LAMP setup06:10
Riesnihilocrat: I basicly did the partitioning myself for both drives... setup RAID1 on the drives... on one pertition I used EXT3, on teh other LVM and XFS... but it worked from the installer06:10

nihilocratah06:16
nihilocratIt's relatively(?) new, and is supposed to be a 'next generation' FS06:16
nihilocratWhich has an extra layer of abstraction from the hardware which is supposed to make it a lot easier for people (particularly sysadmins) to manage06:17

ivoksporkpie: check with dmesg what happend06:19
ivoksi got to go now06:19
nihilocratbye06:19
Riesnihilocrat: Ahhh nice.... I need XFS because it suppose to handle large files better then raiser or ext3....06:20
nihilocratI am slowly doing research in more 'enterprise'-oriented server stuff as I'm being handed higher-traffic and higher-uptime services06:22
Riesnihilocrat: I was doing to same.... hence I picked LVM and XFS06:22
A-Kaser"higher traffic" aq ?06:22
A-Kaseras ?06:22
nihilocratWell06:22
Riescurrently in a default situation XFS outperforms EXT3 at ease..... 60MB/S for a disk to disk copy.... while EXT3 does about 30-40MB/sec06:23
RiesLVM can scale nice..... but I never really did work with it on a live server06:23
nihilocratWe want to move our webserver from Windows Server 2003 to Linux, and we're also running Moodle which is going to go into production in the fall06:23
nihilocratBoth of these boxes are VMs on a VMWare machine06:23
nihilocratI'm the "go to" linux guy after the former "go to" linux guy went off to do higher-paying things06:24
RiesOoo.. I am looking into XEN, http://www.cl.cam.ac.uk/Research/SRG/netos/xen/06:25
Riesfor some of my customer needs....06:25
nihilocratI want to use one of the old servers to run Xen and play around with it06:25
nihilocratThen maybe put low-traffic stuff on it06:25
Riesand customers that need ssh......06:26
nihilocratAs well as a Free/Open/NetBSD install to see what it's like :P06:26
Riesfor freebsd stuff then porkpie knows about it....06:26
nihilocratreally06:26
nihilocratthat's cool06:26
Riesyes.... he runs a couple of freebsd servers....06:26
nihilocratI think one of the cooler parts of virtualization is that it lets you run testing servers without requiring more hardware06:30
Riesthat is true06:30
nihilocratIt makes configuration very modular, so you get the advantages of pizzaboxing without all the waste06:31
A-Kaserand you can move virtual server from one server to another one06:33
A-Kaserjuste by scp06:33
A-Kaserso if one of the virtual server become too big06:33

RiesI think I have something to play with.... A-Kaser since you know the two .... what would you currently recommend xen or vserver?07:44
A-KaserXen have more features07:44
A-Kaserand the network layer is more dedicated to the slave server07:45
A-Kaserbut vserver is very light07:45
A-Kaserso I think it's not vserver vs xen but do you need SSH access or dedicated network layer07:45
RiesI didn't read upon them well... I am interested in it to run it....07:46
A-Kaserin a vserve you cannot change the ip address07:47
A-Kaserthe iptables07:47
A-Kaserand you cannot change your kernel07:48
RiesA-Kaser: that means I can't run apache on port 80 on two different vservers, right? But it is a good solution to run postgresql, apache and maby other services in different vservers. Is that a correct conclusion?07:50
A-Kaserno you can07:50
Ries(assuming the machine has one interface and no virtual interfaces).07:50
A-Kaserit's a real virtualazing07:50
A-Kaseron my workstation I use it to test witch apache1 + php407:51
A-Kaserand another vserver to test apache2 + php507:51
A-Kaserand another to test jboss on port 8007:51
A-Kasereach vserver have an simple IP alias07:52
A-Kaseras you can add with "ip addr add 1.2.3.4/32 dev eth0"07:52
A-Kaseryou need to configure the master vserver to be sure if you have an apache on it07:52
