[01:32] <chmac> I can't resolve www.smile.co.uk through `getent hosts www.smile.co.uk` but it resolves fine through `dig www.smile.co.uk`
[01:33] <chmac> nsswitch.conf reads "hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4"
[01:33] <chmac> resolv.conf lists 127.0.0.1 then my ISP's nameservers
[01:33] <chmac> dig @127.0.0.1 works fine, as does dig @ispnameserver
[01:34] <chmac> I'm not running nscd, I haven't installed it
[01:34] <chmac> Any suggestions other than rebooting?
[02:15] <kgoetz> hi all. has anyone here had systems where the installer gets an IP address, but your still told that network dhcp autoconfig failed and you hae to reconfigure?
[03:22] <cxo> anyone know if i can have ubuntu server install on < 512mb flash?
[03:31] <hessml> good evening
[03:32] <hessml> anyone here have experience with ipmi serial over lan?
[03:38] <cxo> ipmi serial over lan, thats intense
[03:38] <hessml> i sort of have it working
[03:39] <hessml> i get all the boot messages
[03:39] <hessml> i get the login prompt
[03:39] <hessml> i can login
[03:39] <hessml> i get a login message
[03:39] <hessml> then the console locks up
[03:40] <hessml> its driving me nuts
[03:40] <cxo> are you pxe booting?
[03:40] <hessml> no
[03:40] <cxo> which version are you running?
[03:41] <hessml> i followed the  instructions on this page which seemed pretty good execpt for the locking me out https://help.ubuntu.com/community/IPMI
[03:41] <hessml> 8,0.4 server
[03:41] <hessml> intel/amd 64bit
[03:42] <cxo> i honestly dont think anyone in here has the expertise
[03:43] <cxo> ipmi is kinda something only enterprise worries about
[03:43] <cxo> and for very specific tasks
[03:44] <hessml> enterprise? how about us poor people with large clusters of very cheap computers?
[03:44] <cxo> haha
[03:44] <cxo> openmosix, be happy
[03:44] <hessml> openmosix doesn't have ufw
[03:45] <cxo> i heard there is work on shared memory, but havent heard much of it
[03:45] <ScottK> I thought openmosix was shut down.
[03:45] <cxo> kinda
[03:45] <cxo> there is still one or two hackers on it
[03:46] <hessml> anyway, ipmi is available on just about any computer you buy for a CO-LO. It adds about $50-100. It is better than a remote PDU because it gives you more functionality.
[03:47] <hessml> my servers all cost less than a $1000 and they all have IPMI
[03:48] <emgent> Pseudo clustering project --> https://launchpad.net/herd
[03:49] <hessml> so which chat has the IPMI people?
[07:04] <kraut> moin
[07:04] <cxo> moin
[07:05] <cxo> how do you tell gcc which linker to use, and not default to "ld" ?
[07:06]  * kgoetz looks at ebox and wonders what he thinks
[07:06] <kgoetz>   An internal error has ocurred. This is most probably a bug, relevant information can be found in the logs.  An internal error related to a template has occurred. This is a bug, relevant information can be found in the logs.
[07:06] <kgoetz> :| not a lot is the answer
[11:32]  * \sh is stupid somehow
[11:33] <\sh> did anyone has a running config for moinmoin on hardy?
[11:33] <\sh> s/did/does/
[11:36] <\sh> damn..solved
[11:45] <mouser25>  I have setup openvpn and it woks fine,  Im useing it now.  I was wondering if there was a way I could send port specific data across a tun connection insted of static routes for things like irc, aim, msn exct
[11:45] <mouser25>  I dont want to make a static route for every irc server that I would like to connect to
[11:46] <Kamping_Kaiser> perhaps by port
[11:47] <Kamping_Kaiser> use iptables on your gateway to point it over the vpn
[11:49] <mouser25> how will the client know to route the port to the vpn device and not the inet device
[11:49] <Kamping_Kaiser> is vpn running on your local machine?
[11:50] <Deeps> iptables mangle rules?
[11:50] <Deeps> apply a fwmark
[11:51] <Deeps> and then use ip rule to match the fw mark and lookup a different routing table (e.g. vpn table, where the default gw is via your vpn)
[11:52] <Deeps> iirc, -t mangle -I PREROUTING -p tcp --dport 6667 -j fwmark --fwmark 2, would add fwmark #2 to any data going over port 6667
[11:52] <Deeps> s/over/to/
[11:52] <Deeps> google knows better
[11:53] <mouser25> dont know what to look for
[11:53] <Deeps> see the first three things i said
[11:53] <Deeps> iptables, mangle, fwmark, ip rule (part of the iproute package)
[11:54] <Deeps> hell, first hit on google for iptables fwmark looks relevant, bon appetit :)
[11:55] <mouser25> Thanks for pointing me in the right direction
[12:02] <mouser25> now just to find iptables for windows :(
[12:05] <Deeps> heh, windows, forget about it
[12:05] <Deeps> you're also asking the wrong channel too
[12:05] <Deeps> this is #ubuntu-server, not #openvpn or #windows
[12:06] <mouser25> the server is ubuntu
[12:06] <Deeps> and openvpn is running on there?
[12:06] <mouser25> the server side
[12:06] <Deeps> your client side needs to be ubuntu too
[12:06] <Deeps> or at least, linux
[12:06] <mouser25> I know
[12:07] <mouser25> My work computer cant be linux they wont let me
[12:07] <Deeps> as your client side needs to know where to route the packets, and afaik windows doesn't have any tools that can do that
[12:07] <mouser25> bummer
[12:07] <Deeps> then i guess you're SOL for now then
[12:07] <mouser25> well thanks for the help
[12:07] <Deeps> if you're trying to get around work firewalls, my suggestion would be to use putty + dynamic ssh tunnel
[12:07] <Deeps> which creates a local SOCKS proxy for you running on localhost:<whateverport you define in putty>
[12:07] <Deeps> and then tell whichever apps you wanna route around the firewall to use that socks proxy
[12:08] <mouser25> I started out with that, the connection here is so poor that it drops out alot
[12:08] <mouser25> my server is in Iowa and im in Romania
[12:08] <Deeps> if you dont wanna route per ip, ssh tunnel over the pn
[12:08] <Deeps> vpn
[12:09] <mouser25> ok,  That is a good thought
[12:09] <Deeps> it's absolutely horrid and will lead to all sorts of nasties when dealing with dropped tcp packets if your vpn is tcp rather than udp
[12:09] <mouser25> will give that a try
[12:09] <Deeps> but then your vpn shouldn't be any more reliable than your ssh connection if it's tcp anyway
[12:09] <mouser25> it seems to be
[12:10] <Deeps> alternatively, cygwin + autossh could probably serve your needs too
[12:11] <mouser25> it might have more to do with me changing to port 443 and the firewall is leaving my trafic alone now
[12:11] <Kamping_Kaiser> tbh, this is now a ##windows problem.
[12:12] <mouser25> with a posible linux solution :P
[12:12] <Deeps> kaiser's right, but heh, gl finding someone in there with a clue of anything linux related. windows fanboys hate linux much like linux fanboys hate windows
[12:14] <mouser25> Thanks for the help i have to get back to work
[12:15] <Kamping_Kaiser> corp firewalls suck :| glad i dont have one at my current work
[12:15] <Deeps> hehe i love them, the more restrictive the better
[12:16] <Deeps> learn loads trying to break around them
[12:16] <Kamping_Kaiser> there is that, but i learned heaps about windows, and i didnt really want to ;) [i also learned a lot about novell and braindead network design]
[12:17] <Deeps> i still maintain that the ideal desktop is windows xp
[12:17] <Deeps> with a ubuntu vm running in the second screen
[12:17] <Deeps> or vice versa
[12:17] <Kamping_Kaiser> it seems we disagree on that point
[12:17] <Deeps> but i cant work without both
[12:18] <hads> Each to their own
[12:18] <Deeps> one key sticking point i remember from my last job was the complete fail of DFS under samba
[12:18] <Deeps> but yeah, i wouldn't want many windows servers ;)
[12:19] <Kamping_Kaiser> DFS?
[12:19] <Deeps> distributed file system
[12:20] <Deeps> raid over samba, i guess
[12:20] <Kamping_Kaiser> ah, i see
[12:20] <Deeps> remarkably easy to setup
[12:20] <Deeps> many of the windows services are, and work surprisingly well on a small scale
[12:21] <Deeps> if you can get them for free (or close to), it's ideal, as pretty much any numpty can come along and set up all sorts with a few button clicks
[12:21] <Deeps> it's when you try to scale up and start having to pay MS's regular pricing that it stops being particularly useful
[12:21] <Deeps> and/or want internet facing services i guess
[14:27] <lukehasnoname> Happy Canada Day!
[14:31] <nxvl> good morning!
[14:32] <lukehasnoname> Happy Canada Day!
[14:40] <shingalate1> Any reason an ftp user would be able to log in with /bin/bash as their shell but not /bin/false ?
[14:41] <Kamping_Kaiser> yes there is
[14:41] <shingalate1> I'm using vsftpd
[14:54] <shingalate1> oh okay
[15:03] <shingalate1> figured it out /bin/false wasn't listed in /etc/shells
[15:05] <lukehasnoname> I like /bin/stfu better
[15:16] <Ballena> Hi. Does anyone know where I can find a help channel for BitlBee?
[15:32] <mm_202> Hey guys, how would I empty the 'Trash' via the shell?
[15:33] <mm_202> Meh rm -rf .Trash-1000 works.
[17:04] <melter> why don't i get postfix's default /etc/aliases file when i install it?
[17:04] <lamont> did the file already exist?  it won't create one
[17:04] <melter> who owns that file?
[17:04] <melter> if i remove it and reinstall postfix, it creates it
[17:04] <lamont> "the admin" :-(
[17:04] <melter> what package?
[17:05] <lamont> $MTA sort of owns it... I don't know of a single MTA that purges it on --purge
[17:06] <lamont> more to the point, exim4 doesn't
[17:06] <melter> postfix doesn't either
[17:06] <lamont> and it's not attached to any package as a conffile
[17:06] <lamont> melter: right.  I copied the behavior of exim4
[17:07] <melter> postfix has a nice default file containing aliases for abuse, operator, etc., but none of that gets put into the /etc/aliases file
[17:07] <lamont> ah, you mean upstream postfix?
[17:07] <melter> yes
[17:08] <melter> and that's the way it works in gentoo, too
[17:08] <lamont> yeah - I've never grabbed that..  maybe I should
[17:08] <melter> also, the main.cf file is misconfigured by default because if dhclient bugs
[17:08] <melter> *because of
[17:08] <lamont> could you smack a bug into either launchpad or debian's bts asking that the upstream aliases file be delivered on virgin install (or at least something based on it)
[17:09] <lamont> misconfigured in what way?
[17:09] <melter> there's a bug in dhclient that causes it to sometimes not set the hostname provided by the dhcp server
[17:10] <lamont> sounds like a dhcp bug, not a postfix bug... :(
[17:10] <melter> so if i set my hostname to "foo" when i installed, it should be overwritten when i boot, but it doesn't
[17:10] <melter> by default, postfix uses gethostname to get the hostname
[17:11] <melter> but ubuntu re-configures it to foo.example.com, which doesn't exist
[17:11] <lamont> except that the postfix postinst sets myhostname == fqdn
[17:11] <nxvl> nealmcb: about the oscon question, i have just checked my dates and i will be on the states just after the oscon :(
[17:11] <nxvl> so i can't make it
[17:11] <lamont> since historically asking glibc for fqdn got you just the first component..  thanks glibc
[17:12] <nealmcb> nxvl: too bad - looks like a good one
[17:12] <nxvl> yes
[17:12] <nxvl> but i have already ask for my vacations, and have the flight tickets and all
[17:13] <melter> does anyone know how to turn off dhclient? would uninstalling it work?
[17:14] <lamont> network managler kind of likes dhclient
[17:14] <lamont> OTOH, just configuring the interface in /etc/network/interfaces would do that
[17:14] <melter> also, why does hardy ship with such an old version of dhcpcd?
[17:14] <lamont> as in telling it 'inet static' with the right stuff, instead of 'inet dhcp'
[17:16] <lamont> I don't even have a dhcpcd on my machine that I can find...
[17:16] <melter> it's not installed by default, but 3.0.18 has a bug fix i need
[17:16] <melter> and ubuntu ships with 3.0.17
[17:17] <lamont> that would be because 3.0.17 was the current (debian) version at the time that the freeze for hardy hit
[17:17] <lamont> intrepid has 3.2.3-1.1
[17:17] <melter> i know, i already tried it :)
[17:17] <melter> i wish i could put it on production machines right now :)
[17:18] <lamont> "old" equates to < 3 months old at release date, which by most schedules is still pretty shiny-new
[17:18] <lamont> most commercial schedules, that is
[17:19] <lamont> afk for a nit
[17:19] <lamont> bit, even
[17:20] <melter> i'm pretty sure 3.0.18 was out more than just 3 months ago
[17:23]  * delcoyote hi
[17:25] <melter> what's ubuntu-minimal? is it ok to remove it?
[17:28] <nijaba> melter: if you wan't to wipe your install, sure
[17:29] <nijaba> melter: minimal is the smallest set of packages to have ubuntu boot...
[17:31] <melter> so if i let apt-get remove it when i uninstall dhcp3-client, that would be a bad thing
[17:37] <nxvl> ScottK: i find my descriptions very clear
[17:37] <nxvl> ScottK: don't you?
[17:38] <ScottK> nxvl: I'd have to look again.
[17:39]  * ScottK is in a phone meeting right now.
[19:06] <kirkland__> buenos tardes
[19:07] <lukehasnoname> hola
[19:07] <nxvl> kirkland__: buenAs tardes
[19:07] <nxvl> :D
[19:07] <kirkland__> nxvl: :-)
[19:09]  * kirkland__ votes for a UDS on the Mayan Riviera
[19:09]  * lukehasnoname Houston, Texas
[19:09] <nxvl> kirkland__: i'm trying to make all of you come to peru
[19:10] <lukehasnoname> Great... smog and.... green water
[19:10] <nxvl> kirkland__: to see how it is like in the reality
[19:10] <nxvl> :P
[19:10] <kirkland__> *lukehasnoname couldn't be more wrong
[19:10] <lukehasnoname> how so
[19:10] <kirkland__> nxvl: peru sounds great
[19:11]  * ogra still waits for the iceland UDS ... free natural hot tubs everywhere and good beer
[19:12] <lukehasnoname> kirkland__: Have y'all ever thought about how awesome technology is that there are undersea cables connecting us?
[19:14] <kirkland__> lukehasnoname: agreed.  Neal Stephenson's Cryptonomicon has an interesting storyline about undersea cables
[19:14] <lukehasnoname> how am I wrong about Houston?
[19:15] <kirkland__> lukehasnoname: no, you're right, Houston's coastline sucks
[19:15] <lukehasnoname> heh
[19:15] <kirkland__> lukehasnoname: I'm talking about the Yucatan Pennisula, Carribean side
[19:15] <kirkland__> Houston != Mayan Riviera, not sure where you got that from
[19:15] <lukehasnoname> I like Houston, and I love the coast, but our water isn't the clearest
[19:15] <lukehasnoname> as in, it's opaque
[19:16] <lukehasnoname> but I still play in it
[19:18] <nxvl> Lima is in the coast
[19:18] <nxvl> :D
[19:20] <melter> what's the proper way to remove dhcp3-client? "apt-get remove dhcp3-client" will also remove ubuntu-minimal
[19:21] <nxvl> ubuntu-minimal is just a metapackage
[19:21] <nxvl> to install more other packages
[19:21] <nxvl> so it doesn't hurt to remove ir
[19:21] <nxvl> it
[19:22] <melter> nxvl, that's not what nijaba said earlier
[19:22] <melter> "if you wan't to wipe your install, sure"
[19:23] <melter> "minimal is the smallest set of packages to have ubuntu boot..."
[19:24] <nxvl> yes
[19:24] <nxvl> but ubuntu-minimal is just a metapackage
[19:24] <nxvl> the rationale is:
[19:24] <nxvl> if some package tries to remove ubuntu-minimal it is needed
[19:24] <nxvl> but if you want to remove it for some reason
[19:24] <lukehasnoname> Meaning it's likea shopping cart of packages. Once you put the packages in the pantry (your computer) you dont' need the cart
[19:24] <nxvl> is up to you
[19:25] <nxvl> the problem here is dhcp3-client not ubuntu-minimal
[19:25] <nxvl> :D
[19:25] <melter> nxvl, YES
[19:25] <nxvl> i mean
[19:25] <nxvl> the one who will break you system
[19:26] <nxvl> lukehasnoname: exactly
[19:35] <lukehasnoname> must... learn... LDAP...
[19:37] <lukehasnoname> l33t
[19:48] <jpds> So... find a book on it.
[19:48] <lukehasnoname> I know
[19:49] <lukehasnoname> don't hate, jpds
[19:49] <RoAkSoAx> lol
[19:54] <mathiaz> kees: jdstrand: what would you answer to bug 244406 ?
[19:54] <uvirtbot`> Launchpad bug 244406 in mysql-dfsg-5.0 "File load data infile'file-name' fails" [Undecided,Won't fix] https://launchpad.net/bugs/244406
[19:57] <jdstrand> mathiaz: I agree with the "Won't Fix", but might guide him on how to add /var/www to the profile rather than just going with complain mode
[19:57] <jdstrand> mathiaz: this statement is false: "mysqld already applies the necessary restriction and that the apparmor restriction is redundant"
[19:58] <jdstrand> mathiaz: in the very limited scope of what he is trying to do, that is correct, but considering mysqld as a whole, it is not accurate
[20:02] <kees> mathiaz: I've got nothing to add.  :)  jdstrand covered it with the "add what you need" part.  People will slowly get used to the extra MAC systems, and they just need to add more perms.
[20:19] <[diablo]> evening #ubuntu-server
[20:19] <[diablo]> guys, xen / ubuntu 8.04 related q's
[20:19] <[diablo]> ?
[20:19] <[diablo]> #?
[20:23] <jpds> !ask | [diablo]
[20:23] <[diablo]> !ask sarcasm
[20:23] <[diablo]> ;)
[20:24] <[diablo]> ok.. well, I've been using KVM for quiet some time, maybe near 1 year... Today I started with new company, and their very into Xen ... I had a proper headache with 8.04 (x64) and xen
[20:25] <[diablo]> broken packages
[20:25] <[diablo]> no intel graphics support
[20:25] <[diablo]> when booting xen kernel
[20:25] <[diablo]> now I know (and I completely agree with) that Ubuntu is geared towards KVM
[20:26] <VilasBoas> hey i need a litle help
[20:26] <VilasBoas> I'm installing on my ubuntu hasrdy a Lamp server but the phpmyadmin isn't working it can't find it :(
[20:26] <[diablo]> but should I drop for the moment even the idea of getting Xen running nicely in Ubuntu?
[20:26] <[diablo]> I'm assuming less attention is going to be paid to the fixes and patches than KVM
[20:28] <[diablo]> here @ home.. I installed xen on my Q6600 box  ....  the nvidia drivers seem not to have been built around the xen kernel...
[20:28] <[diablo]> it's a touch frustrating to use nv
[20:29] <[diablo]> VilasBoas, you 'cant find it'
[20:29] <[diablo]> ?
[20:29]  * [diablo] advises VilasBoas to look under his bed
[20:29] <VilasBoas> Diablo: do you whant to go .........
[20:29] <[diablo]> VilasBoas, you've installed it right?
[20:31] <VilasBoas> yes i have but when i go to http://localhost/phpmyadmin it appears black
[20:31] <[diablo]> black?
[20:32] <VilasBoas> yes black
[20:33] <[diablo]> you checked the apache logs?
[20:34] <VilasBoas> if it is working
[20:34] <VilasBoas> the apache logs
[20:34] <[diablo]> any messages
[20:35] <VilasBoas> it's working
[20:35] <[diablo]> but look in the logs
[20:35] <[diablo]> it must say something
[20:35] <VilasBoas> how can i do that?
[20:35] <[diablo]> erm
[20:36] <[diablo]> in the /var/logs/apache
[20:36] <VilasBoas> i was folling the instrutions in http://www.guiaubuntupt.org/wiki/index.php?title=Ubuntu_hardy
[20:36] <[diablo]> no idea, i don't follow tutorials to do things like that
[20:36] <VilasBoas> of how to install a lamp server
[20:36] <VilasBoas> :(
[20:37] <[diablo]> VilasBoas, I assume there is some documentation on the ubuntu site
[20:38] <[diablo]> a LAMP is more than common
[20:39] <VilasBoas> ok thank you
[20:39] <VilasBoas> :(
[20:40] <[diablo]> VilasBoas, https://help.ubuntu.com/8.04/serverguide/C/index.html

[22:01] <VilasBoas> i have a big problem i was trying to install a LAmp server but when i try to open a php file the firefox ask me if i what to save or to open the script
[22:02] <VilasBoas> can anyone please help me
[22:05] <nxvl> ok back
[22:05] <nxvl> any results?
[22:08] <joebob777as7> I set up a hardy server and install gnome. I want to add a printer to be able to share it and printers doesn't show up under the control panel...
[22:09] <joebob777as7> can someone point me in the right direction?
[22:15] <soren> nxvl: Worked for zul.
[22:16] <soren> nxvl: I'm building on intrepid now. I failed on hardy.
[22:16] <soren> joebob777as7: #ubuntu
[22:17] <soren> VilasBoas: Your apache server isn't interpreting your php files. Restart apache, and try again after you've completely restarted your web browser.
[22:17] <soren> They have an annoying tendency to cache mimetypes.
[22:19] <soren> nxvl: zul didn't have any lintian warnings either, by the way.
[22:20] <nxvl> \o/
[22:20] <soren> nxvl: By the way: I know that norsetto found some mistakes in your copyright file, but I have to say I was impresed at the copyright file that was already there.
[22:20]  * nxvl HUGS soren and zul 
[22:20] <nxvl> yeah, i fixed thos warning already
[22:21] <nxvl> soren: thanks! i was trying to have it really explicit
[22:21] <soren> Yeah. Good job.
[22:21] <soren> Sometimes I think getting the copyright file right is the hardest part of packaging. :)
[22:22] <nxvl> yes
[22:22] <nxvl> not the hardest, but the teduis
[22:23] <ScottK> It's the area where I most often find problems in a package after another MOTU has given it a +1.
[22:23] <nxvl> yeah, we are developers, not lawyers, so most people focus more on techical things
[22:24] <ScottK> OTOH, it's a wonderland for the pedantic.  I've found debian/copyright problems in packages put up for review by an archive admin.
[22:34] <soren> ScottK: Heheh :)
[22:34]  * soren wanders off
[22:51] <nxvl> soren: http://revu.ubuntuwire.com/details.py?package=augeas <- 0.2.1 is out
