| nandemonai | greetings | 12:20 |
| === AviaX [n=aviax@i3ED6CE08.versanet.de] has joined #ubuntu-server | ||
| nandemonai | I've just installed tripwire and set it up (via apt-get install tripwire) but it appears I've missed something.. when trying to run a test I get /var/lib/tripwire/inserthostnamehere.twd No such file or directory | 12:23 |
| nandemonai | Any ideas? | 12:23 |
| allee | nandemonai: dpkg -L tripwire | grep -i inserthostnamehere should tell you if the file is at a different location or missing from the pkg | 12:25 |
| spike | yeah, sounds like the hostname hasnt been configured at install time | 12:26 |
| nandemonai | ok I'll give it a go, thanks | 12:26 |
| nandemonai | That command returned nothing.. | 12:27 |
| nandemonai | And yes I did replace it with the REAL hostname :P | 12:27 |
| spike | nandemonai: have you checked config in /etc/ ? maybe the value hasnt been correctly stored in there | 12:29 |
| nandemonai | You mean the tripwire conf? | 12:30 |
| === mgalvin [n=mgalvin@ubuntu/member/mgalvin] has joined #ubuntu-server | ||
| nandemonai | I'm new to tripwire btw.. | 12:31 |
| nandemonai | the twcfg.txt has this line.. DBFILE =/var/lib/tripwire/$(HOSTNAME).twd I assume the parsed version is taken from that.. | 12:34 |
| nandemonai | I'll try running through tripwire --init and see if that creates the db properly.. | 12:36 |
| nandemonai | Oh wait.. I think I know what's wrong.. I assumed that the apt-get install did all that when I ran through setting up the pass phrases etc.. Guess I assumed wrong. My apologies. | 12:38 |
| Plug | hi ajmitch | 12:40 |
| spike | nandemonai: what does "hostname" command gives back to you? | 12:40 |
| nandemonai | my hostname, like it should.. nvm me, just having a blode moment.. | 12:43 |
| nandemonai | *blonde | 12:43 |
| nandemonai | The db hadn't been created.. | 12:43 |
| nandemonai | All appears well now tripwire --init went through | 12:44 |
| nandemonai | I just figured that was done in the initial config options after I apt-get installed it.. Never assume! :) | 12:44 |
| Plug | allee: thanks, adding arcmsr to the modules file indeed makes the system boot | 12:45 |
| allee | good guess eh? :) congrats plug! | 12:46 |
| allee | Plug: curious: what vendor/model (the computer, not the controler) showed this bug? | 12:51 |
| Plug | It's a SuperMicro mainboard | 12:52 |
| allee | 'k thx | 12:53 |
| Plug | (raised bug 40075) | 12:54 |
| Overand | So, I've got an ubuntu-server install (Dapper, FC6), and I've got a kernel with a PREEMPT tag | 12:58 |
| Overand | I thought one of the ideas of ubuntu-server was to avoid the preempt kernel features. | 12:59 |
| Plug | Now to learn all about LVM snapshots. | 01:20 |
| AviaX | hi all | 01:46 |
| AviaX | @Overand what is it about preempt? | 01:46 |
| === nandemonai_ [n=nandemon@ppp231-175.lns2.adl4.internode.on.net] has joined #ubuntu-server | ||
| neuralis | Overand: that's probably because you haven't got the -server kernel running (it might still not be enabled by default). you'll want to install the server kernel package. | 02:07 |
| Overand | neuralis: yeah? | 02:11 |
| Overand | ahh | 02:12 |
| Overand | linux-image-amd64-server | 02:12 |
| Overand | Hope that's an SMP kernel | 02:12 |
| Overand | holy nuggets, the package is 21 megs | 02:12 |
| Overand | neuralis: thanks. =] | 02:15 |
| Overand | now to see if my grub config is correct and will load that kernel by default | 02:15 |
| Overand | Fortunately I haven't colocated the server yet, so if it doesn't, it's not a big deal. | 02:16 |
| Overand | Rad. Works. | 02:17 |
| neuralis | which version of ubuntu-server did you download? | 02:19 |
| Overand | Dapper, Flight 6 | 02:20 |
| neuralis | flight6, or a more recent daily? | 02:20 |
| neuralis | ah. | 02:20 |
| Overand | I also haven't yet done an apt-get upgrade | 02:20 |
| Overand | Just for kicks I'm running bonnie++ to see if there's any difference, but since there's nothing else really eating CPU time on the box, I seriously doubt it | 02:21 |
| neuralis | the current seeds show that the server kernel should be installed by default, so the dailies should have this problem removed. | 02:22 |
| AviaX | im using the daily version from april 17th and uname says:Linux fireball 2.6.15-20-386 #1 PREEMPT Tue Apr 4 17:48:51 UTC 2006 i686 GNU/Linux | 02:25 |
| neuralis | hm. | 02:26 |
| neuralis | fabbione: can you look into this? it seems like we're still installing the desktop kernel by default on u-s installations. | 02:26 |
| neuralis | AviaX: did the installation work well with you otherwise? | 02:26 |
| neuralis | s/with/for/ | 02:26 |
| AviaX | yes without problems | 02:27 |
| neuralis | good to hear. | 02:27 |
| AviaX | :-) | 02:27 |
| AviaX | should i switch kernels? | 02:28 |
| neuralis | AviaX: yes. | 02:28 |
| neuralis | Overand: you? any issues or problems with the install or deployment that i should know about? | 02:28 |
| Overand | I had serious problems with my install of flight 6 actually | 02:28 |
| Overand | I installed with XFS | 02:28 |
| Overand | and grub didn't install | 02:28 |
| Overand | got the 'unsupported arch.' message | 02:29 |
| Overand | "GRUB didn't install. This may have been because you were..." etc | 02:29 |
| Overand | Ubuntu-server, Flgiht 6, AMD64, and my drives were on a 3ware raid card. | 02:29 |
| Overand | I installed with EXT3 and it was fine. | 02:29 |
| Overand | I had another problem, but I'm not sure what it was. I had to use a different CD drive... | 02:29 |
| Overand | It's on a 1U server, and it has a built-in laptop CD drive. | 02:30 |
| Overand | The install 'hung' past a certain point, checked dmesg, DriveReady SeekComplete errors | 02:30 |
| Overand | so i figured, bad burn, made a new one. | 02:30 |
| Overand | same problem, similar spot. | 02:30 |
| Overand | so i swapped out the laptop drive for another laptop drive, same problem, different spot | 02:30 |
| Overand | so using the *same controller* on the board, I put in a standard IDE CD drive | 02:30 |
| Overand | and the installation went fine... | 02:31 |
| Overand | And yes, I verified the CDs, verified fine on another computer, verify hung on the laptop drives. | 02:31 |
| Overand | I don't think I can really blame that on ubuntu-server though, that could be *so* many different things | 02:31 |
| Overand | But a brand new laptop CD drive, and a known-good one both having problems in the same area, while a 'normal' cd drive hooked to the same port on the board worked fine? Very odd. | 02:31 |
| AviaX | which kernel should i'll take then, linux-image-2.6.15-20-server? | 02:33 |
| Overand | AviaX: what's your processor? | 02:34 |
| AviaX | athlon 2500+ | 02:34 |
| AviaX | eh sorry, athlon mp 1600+ | 02:34 |
| Overand | ohh. | 02:35 |
| Overand | dual? | 02:35 |
| AviaX | nope | 02:35 |
| Overand | or just one MP? =] | 02:35 |
| Overand | just one MP? | 02:35 |
| AviaX | yes | 02:35 |
| Overand | ... is it a dual proc board? | 02:35 |
| Overand | well either way that is probably the right package for you | 02:35 |
| AviaX | nope, just a mobile athlon in a standard desktop board | 02:35 |
| AviaX | k i see | 02:36 |
| Overand | MP isn't "mobile athlon" | 02:36 |
| Overand | the MP is the 'dual CPU capable' athlon | 02:36 |
| AviaX | oh ok i see, good to know :-/ | 02:36 |
| Overand | hey, pick up another and find a cheap MP board | 02:36 |
| Overand | or not | 02:36 |
| Overand | I love my Dual MP 1900+ system | 02:36 |
| Overand | Of course, it's running 'that other operating system' right now =/ | 02:37 |
| AviaX | so i have a mobile athlon not a MP :-( | 02:37 |
| Overand | k | 02:37 |
| AviaX | so what i need for switching kernels, i made my last kernel over a year ago on a gentoo system | 02:38 |
| Overand | WOW. | 02:40 |
| Overand | file creation speed more or less doubled between these two kernels | 02:40 |
| Overand | 1500/sec on the preempt, 3200/sec on the -server one | 02:40 |
| Overand | diskwrite being sliiightly slower | 02:41 |
| Overand | like a percent at most | 02:41 |
| AviaX | i see | 02:41 |
| AviaX | do i just need the kernel package? | 02:41 |
| Overand | wow. | 02:43 |
| neuralis | Overand: the server kernel uses a different IO scheduler. | 02:43 |
| Overand | performance is better in terms of responsiveness when I have ~16 instances of nice -9 bzip2 -9 </dev/urandom >/dev/null | 02:43 |
| Overand | now i'll try my 'bonnie while that's running' thing | 02:44 |
| Overand | I'm still sort of 'eh' about running EXT3 | 02:44 |
| neuralis | Overand: please post a detailed report of your installation problems to the ubuntu-server list; this is pretty critical information. | 02:44 |
| Overand | neuralis: I'm not sure how detailed I can make it, but I'll do what I can. | 02:44 |
| Overand | URL for the list? | 02:44 |
| Overand | I'm relatively new to the ubuntu community, and haven't participated on any lists. | 02:45 |
| neuralis | Overand: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server | 02:45 |
| neuralis | Overand: welcome on board. | 02:45 |
| Overand | =] | 02:45 |
| Overand | Thanks. | 02:45 |
| Overand | Should I bother with the DriveReady SeekComplete one? | 02:45 |
| neuralis | probably not; it doesn't sound like it's a software issue. | 02:46 |
| Overand | It feels like a compatability problem, but it could just be a case of laptop CD drives not liking the CD-R | 02:46 |
| Overand | It's just odd that two different laptop drives on the same controller would fail, but a standard one on the same one would work. | 02:46 |
| Overand | The XFS thing was too bad, though. | 02:46 |
| neuralis | Overand: i don't know what your experiences with xfs are in production, but i'd never recommend using it in a serious environment. | 02:47 |
| Overand | neuralis: I've heard very mixed reports. | 02:52 |
| Overand | I went mostly on the word of someone who I trust, but... | 02:52 |
| neuralis | Overand: i've had nothing but grief with xfs blowing up in several production and testing environments. | 02:53 |
| Overand | cute | 02:54 |
| === ajmitch still sticks solely with ext3 | ||
| neuralis | ajmitch: agreed. | 02:57 |
| neuralis | Overand: ext3 is about as rock-solid as journaling filesystems come these days. unless you have to have breakneck performance, it's good enough that the other FSes don't even merit much consideration. | 02:58 |
| ajmitch | I still don't have access to those T2000s, thanks to uni ITS :) | 02:58 |
| Overand | neuralis: that's sort of how I Fel | 03:00 |
| Overand | ...feel | 03:00 |
| Overand | I'll see how the system works out. As it stands, it's already grossly overpowered for what I need, but with luck it'll get busy. | 03:01 |
| ajmitch | how overpowered is it? | 03:02 |
| Overand | Athlon X2 4200+, 2 gigs of CAS2 ram, but just two 250 gig SATA drives (16 meg cache) in RAID 1 on a 2 port 3ware controller | 03:04 |
| ajmitch | not too bad | 03:05 |
| Overand | So I didn't go nutso 15k RPM SCSI drives in 0+1 or anything | 03:05 |
| h3sp4wn | having /var/spool on reiser-fs significantly improves the response time of webcaching | 03:05 |
| Overand | The X2 thing was sort of a no-brainer | 03:05 |
| Overand | found a Tyan barebones system that sells for ~$600 that's 1U and supports the X2 chips, but is a pretty decent board, has 4 built-in hot-swappable HDs, etc | 03:06 |
| === ajmitch has similar specs for a desktop box at home | ||
| Overand | yeah | 03:07 |
| Overand | same here | 03:07 |
| neuralis | Overand: thanks for the report. | 03:14 |
| Overand | No problem. | 03:15 |
| Overand | Apparnetly my e-mail client uses my first name. Oh well, heh. | 03:15 |

| nawty | Guys, what's the major difference with the -server kernel? | 09:52 |
| neuralis | nawty: no kernel preemption, deadline io scheduler, 100hz clockfreq. | 09:58 |
| neuralis | nawty: + smp and basic numa. | 09:59 |
| infinity | s/smp/smp support for hideously large numbers of CPUs/ | 10:05 |
| infinity | (The desktop kernel does SMP) | 10:05 |
| infinity | Err, if by "desktop", I mean "desktop kernel that isn't -386", of course. | 10:06 |
| === thefish [n=thefish@unaffiliated/thefish] has joined #ubuntu-server | ||
| neuralis | infinity: right. | 10:11 |
| neuralis | infinity: what scheduler does the desktop kernel use? cfq? | 10:11 |
| infinity | Whatever the default is. I always forget. | 10:19 |

| fabbione | tarvid: you are in the wrong channel | 06:07 |
| fabbione | ask this stuff in #ubuntu | 06:07 |
| tarvid | that may be but the question is how much do I have to install to get pgadmin to run remotely | 06:08 |

| fabbione | it's not an ubuntu-server question | 06:11 |
| tarvid | it is precisely an ubuntu server question | 06:11 |
| tarvid | if ubuntu is going to support postgresql which is a server not a desktop application | 06:12 |
| tarvid | so what does it take to get pgadmin3 to run on a server installation | 06:12 |
| tarvid | it is at least a bug in dependencies or configuration | 06:13 |
| neuralis | pgadmin3 | 1.2.2-1.1 | http://archive.ubuntu.com dapper/universe Packages | 06:14 |
| neuralis | tarvid: so ubuntu doesn't support it, and you're asking in the wrong channel; it's a general ubuntu question, so please use #ubuntu. | 06:14 |
| tarvid | by not supporting pgadmin3, there is less than full support of postgresql | 06:15 |

| redguy | hi there | 08:36 |
| redguy | is the information concerning this channel on https://wiki.kubuntu.org/InternetRelayChat accurate? | 08:37 |
| redguy | I mean, isn't this a support channel? The wiki clearly says that this channel is a "team channel". Is pointing users from #ubuntu to this channel for support with ubuntu server wrong? | 08:39 |
| spike | redguy: point is definition of "related to ubuntu-server" | 08:46 |
| redguy | spike: indeed | 08:46 |
| spike | redguy: ppl thinks since they downloaded ubuntu-server, installing vim is a server question, but of course it's not | 08:46 |
| spike | I guess that's the most common problem | 08:46 |
| redguy | spike: is ubotu's factoid like this? | 08:48 |
| spike | redguy: what sorry? | 08:49 |
| redguy | spike: erm, is ubotu's server factoid correct now? I made ubotu pm you the factoid. | 08:50 |
| spike | oh, sry, [notice(ubotu)] Your query got blocked. :) | 08:52 |
| spike | hang on | 08:52 |
| redguy | Ubuntu 5.10 Server is out! http://lists.ubuntu.com/archives/ubuntu-announce/2005-October/000042.html, for server related questions join #ubuntu-server | 08:52 |

| === mgalvin [n=mgalvin@ubuntu/member/mgalvin] has joined #ubuntu-server | ||
| spike | redguy: I'd rather say something like "ubuntu server edition available. stable breezy 5.10, something else dapper... for server related questions..." | 08:54 |
| redguy | spike: actually, only the "for server related..." bit is mine... I'll change the other part | 08:56 |
| spike | maybe a good thing could be referring a page explaining what's a "server related question", just to reduce the noise ration... not that it's unbearable atm. | 08:56 |
| spike | redguy: https://wiki.kubuntu.org/InternetRelayChat#ubuntu-server, something like that maybe | 08:57 |
| redguy | spike: is "server related" explained somewhere on the wiki? | 08:58 |
| spike | I dont think so, we actually havent got a page explaining exactly what a server edition is afaik | 08:59 |
| spike | guess I can write one and post it on the ML for review | 08:59 |
| redguy | spike: in fact, I wanted to ask you that question :-) | 09:00 |
| spike | ok, doing a search on the wiki just in case | 09:00 |
| redguy | spike: what is the server edition? i presume that server edition != server install | 09:00 |
| spike | redguy: they're same stuff | 09:02 |
| spike | server install will install the same stuff installed by the server iso | 09:02 |
| redguy | spike: ah, so it's the packages on the CD that are different, right? | 09:03 |
| spike | redguy: thinks so, yeah. actally I d/l'ed a warty cd a long ago, and since then no more iso for me but server ones | 09:05 |
| redguy | Ubuntu Server Edition is a release of Ubuntu designed especially for server environments. The default install includes a smp kernel and no GUI. The install CD contains many server apprications. Current stable version is 5.10. For server related questions join #ubuntu-server | 09:08 |
| redguy | spike: that's what it looks like now | 09:09 |
| redguy | spike: would you include the wiki article later? | 09:09 |
| spike | redguy: yeah, when the page is ready I'd take off the second and third statements and link the wiki page. and add a "see channel policy: + link to wikipage" | 09:12 |
| spike | at the end | 09:12 |
