[04:23] <lwizardl> hello
[06:59] <ramsay_za> morning is there any way to setup mdadm raid arrays when juju bootstraps a server?
[08:12] <elemay2> hi, im on ubuntu server 12.04 x64, i have 2 nics (both e1000 / Intel Pro 1000). These are configured as bond0, one of them is only getting 100mbps link. i changed the card already with another one and also changed the nw-cable, i also switched the ports on the switch. any hints for this?
[08:33] <sveinse> I'm running 12.04 amd64 server (kernel 3.2.0-37-generic #58) on a VMware vCenter Server (5.1.0). I'm having regular problems with the kernel crashing. Invalid opcode 0000 in highmem.h:194. Ubuntu runs the latest VMWareTools. Any ideas?
[08:34] <sveinse> Natty on the same datacenter does not show this behaviour
[08:41] <vedic> How to disable single user mode login? or is there any way to protect colocated servers at remote place? (I do need server restart though)
[08:47] <cnf> hi
[08:47] <cnf> when using a preseed installation, is there a way to get the installer to ask confirmation for prefilled values?
[08:50] <rbasak> cnf: you can avoid setting priority on the kernel commandline. Or set it to low for even more questions
[08:50] <cnf> rbasak: how does that get me prefilled questions?
[08:51] <cnf> i want no questions, except for network configuration
[08:51] <cnf> and i want those fields prefilled with defaul values
[08:51] <rbasak> Oh, I see. I'm not sure you can do that.
[08:51] <rbasak> Questions you are asked are based on their priority
[08:51] <cnf> hmm
[08:52] <rbasak> Preseeding sets defaults in advance. I believe the two mechanisms are entirely independent
[08:52] <cnf> i can get it to prompt for network settings
[08:52] <cnf> but i would like to prepopulate for example our dns servers
[08:52] <rbasak> Maybe there's another mechanism I'm unaware of
[08:52] <rbasak> Why not just use DHCP?
[08:52] <cnf> uhm, because there is no dhcp on our network
[08:53] <cnf> at all
[08:53] <cnf> anywhere
[08:53] <rbasak> Put one in then :)
[08:53] <cnf> why would we do that?
[08:53] <rbasak> So that you don't have to input network settings
[08:53] <cnf> we'd have to run maybe 50 dhcp servers
[08:54] <cnf> not much of a solution :P
[08:54] <rbasak> Crazy
[08:54] <cnf> rbasak: probably about 200 physical machines (not counting customer machines) with in all 300 or 400 OSes running on 50ih vlans?
[08:55] <rbasak> At that scale you should have everything fully automated then
[08:55] <cnf> legacy is a horrible thing :P
[08:55] <rbasak> Use a provisioning vlan with one dhcp server
[08:56] <cnf> which entails switching around vlans left and right
[08:56] <cnf> like i said, legacy is a horrible thing
[09:35] <vedic> How to disable single user login to improve security of the server? What is the best practice?
[09:39] <agu10^> I am unable to understand how to set up virtual hosts properly. Tutorials send me to edit DIFFERENT config files. This inconsistency troubles me. am I not supposed to have one file per virtual host at sites-available ??  tutorials make me edit httpd.conf, or add a new file "virtual.conf", or stuff like that. But i believe neither is the right approach. any clues? I have added a file at /etc/apache2/sites-available/potentialstudio.com .
[09:39] <agu10^> .. but it's not doing anything
[09:44] <cnf> rbasak: from #ubuntu-installer:
 d-i name/of/question string value
 d-i name/of/question seen false
 https://help.ubuntu.com/12.04/installation-guide/i386/preseed-advanced.html#preseed-seenflag
[09:45] <cnf> for future reference
[09:45] <rbasak> Ah, handy
[09:45] <rbasak> Thanks
[09:45] <cnf> yeah, indeed
[09:57] <jpds> vedic: What are you trying to do?
[09:57] <jpds> vedic: Disable the recovery mode?
[10:00] <vedic> jpds: Server is colocated and placed at remote location.  Just thought to increase its security if somebody try logging in as single user mode
[10:00] <jpds> vedic: If they have physical access, there's not much you can do.
[10:01] <vedic> jpds: yea, live cd is always an option.
[10:01] <jpds> vedic: LiveCD, ripping the hard drives out.
[10:04] <jpds> vedic: All I can really suggest is putting non-system files on an encrypted partition.
[10:04] <jpds> But then every time the server boots, you'll have to manually mount that partition.
[10:05] <vedic> jpds: I think that would stop running programs reading files. I have my codes and data text files in home dir and encrypting that would cause programs to not function properly
[10:06] <jpds> vedic: Yeah, I'm thinking non-home dir encryption.
[11:23] <hackeron> I'm trying to install ubuntu on a blank hard-drive connecting to an exiting ubuntu server. I have most of the progress figured out - but I cannot get it to boot. I just see a white blinking cursor and the grub menu never shows up. I think my partitioning code must be wrong: http://pastie.org/6173525 -- any ideas what is wrong with that?
[11:24] <cfhowlett> hackeron, probably a grub configuration issue, i.e. grub has to be directed to the bootable media
[11:25] <freesbie> hackeron: have you done a grub-install on the new disk ?
[11:26] <hackeron> freesbie: yes, I did grub-install $DRIVE - it said installed without issues
[11:27] <hackeron> freesbie: if I change the label from gpt to msdos - instead of a blinking white cursor, I get a reboot loop
[11:28] <hackeron> cfhowlett: yes, this is what I'm doing with parted $DRIVE -- set 1 bios_grub on
[11:52] <freesbie> hackeron: you may have to give it --boot-directory=DIR aswell
[11:58] <hackeron> freesbie: but it's /boot which is the default :/
[11:59] <agu10^> I can't get apache2 to start! root@domU-12-31-39-10-4A-43:/etc/apache2# service apache2 start
[11:59] <agu10^>  * Starting web server apache2                                                  Action 'start' failed.
[11:59] <agu10^> The Apache error log may have more information.
[12:00] <greppy> agu10^: what do the logs tell you?
[12:00] <agu10^> nothing at all
[12:01] <agu10^> the last log was hours ago
[12:01] <agu10^> when it still worked
[12:01] <greppy> so there is nothing in /var/log/apache2/error.log?
[12:01] <agu10^> nothing new. and nothing related to this failure
[12:01] <agu10^> last log there is from 2 hours ago
[12:01] <agu10^> a GET request
[12:01] <greppy> is that where it is still configured to log to?
[12:01] <agu10^> but now it's not even STARTING
[12:02] <agu10^> yes, as far as i know, yes
[12:02] <agu10^> i didn't change it
[12:04] <greppy> agu10^: what about sudo apache2ctl configtest
[12:04] <greppy> ?
[12:04] <agu10^> Syntax OK
[12:04] <greppy> got me then.
[12:05] <greppy> I'd double check that the logs are still going to where you expect
[12:06] <agu10^> how do i know?
[12:06] <greppy> look in the configuration files in /etc/apache2
[12:06] <bitnumus> Hi, im trying to install ubuntu-server, the installation failed at loading the CD-ROM stage, any way to find out why?
[12:07] <agu10^> greppy, i did
[12:08] <cfhowlett> bitnumus, any error messages?  also did you md5sum the iso?
[12:08] <agu10^> ErrorLog ${APACHE_LOG_DIR}/error.log
[12:08] <bitnumus> i did md5sum the ISO yea
[12:08] <bitnumus> it failed 4 times, i tried formatting the USB to fat32 etc
[12:09] <gregory58> Hello, I am following a Railscast(http://railscasts.com/episodes/335-deploying-to-a-vps) to deploy to DO, but I am getting a "bash: vim: command not found" error when I input "vim ~/.bashrc "
[12:09] <cfhowlett> bitnumus, bootable cd/dvd? or usb?
[12:09] <bitnumus> cfhowlett, USB
[12:09] <bitnumus> using 'unetbootin'
[12:09] <cfhowlett> bitnumus, easy check: different usb.  they do get squirrely ...
[12:10] <bitnumus> hmm, not sure i have another one handy
[12:10] <bitnumus> worth 00'ing it or something?
[12:11] <cfhowlett> bitnumus, just format as normal I'd say
[12:11] <bitnumus> yea i did that using gparted
[12:13] <bitnumus> cfhowlett, i ran 'check disk integrity' and it fails on a file saying 'file failed the Md5 checksum verifitcation'
[12:13] <bitnumus> Is there an alternative to unetbootin i can try, to rule that out ?
[12:13] <hackeron> freesbie: I get this: # grub-install --boot-directory=/boot /dev/sdi
[12:13] <hackeron> Installation finished. No error reported.
[12:14] <hackeron> but when I try to boot, I just see a white blinking cursor and the grub menu is never shown - I think it is the partition table to blame
[12:16] <cfhowlett> bitnumus, this is your downloaded iso?  if it failed download again.  I'd use the torrent for best results...
[12:17] <bitnumus> cfhowlett, i downloaded it from releases.ubuntu.com
[12:17] <bitnumus> and the md5sum of the download is correct
[12:18] <cfhowlett> bitnumus, so on installation it reads an error?  the bootable usb is fragged.  do it again - perhaps with startupdiskcreator?
[12:18] <bitnumus> im trying startup disk creator now
[12:18] <bitnumus> i ran 'check disk integrity' and it fails on a file saying 'file failed the Md5 checksum verifitcation'
[12:18] <bitnumus> it fails on loading files from CD-ROM
[12:19] <bitnumus> it boots fine
[12:20] <cfhowlett> bitnumus, you're reading inconsistent feedback ... clearly there's an error here.  either hardware or software fail...
[12:20] <gregory58> Anyone know how to install vim on a Ubuntu VPS like Digital Ocean....I'm getting a vim: command not found error
[12:20] <freesbie> hackeron: maybe it is, I remember having some problems with GPT and grub, had to make a bit of free unpartitioned space to make it work. but that was on virtual machines, afair I initiated grub from within a chroot on the disk-image
[12:21] <cfhowlett> bitnumus, option?  install the mini.iso and download then add the packages you need via internet...
[12:21] <cfhowlett> and don't use CD-rom?
[12:21] <bitnumus> cfhowlett, ill try this startup disk creator and see what happens
[12:21] <bitnumus> im not using a CD-ROM
[12:22] <hackeron> freesbie: yeh, that's pretty much what I'm doing except not on a virtual machine - I'm doing chroot /tmp/target and then running the grub-install - I tried to leave the free space in my partitioning: http://pastie.org/6173525 - but it just wont boot :/
[12:22] <bitnumus> thats what the installer calls it
[12:34] <mah454> Hello
[12:34] <mah454> I installed mysql in ubuntu 12.10
[12:34] <mah454> but have not log in /var/log for mysql !
[12:35] <mah454> How can enable mysql log ?
[12:36] <andol> mah454: /etc/mysql/my.cnf
[12:36] <mah454> andol: what line must change ?
[12:37] <andol> mah454: That depends what kind of logging you want. Tried searching for the word log in the file?
[12:39] <mah454> andol: mysql authentication (User Login or Logout)
[12:41] <andol> Not sure about that particular case.
[12:45] <agu10^> I try to create a new "default" website for apache2 but with the name "wildcard"
[12:45] <agu10^> is it impossible to create it under a name other than "default" ???
[12:52] <Daviey> zul: thanks for replying to the openstack list.
[12:52] <zul> Daviey: no worries
[13:07] <jamespage> zul: http://people.canonical.com/~jamespage/ca-updates/ review please
[13:07] <jamespage> :-)
[13:07] <zul> awesome-o +1
[13:11] <Daviey> that was the fastest review ever. :)
[14:53] <jamespage> ivoks, think I figured out some of those glance errors from the other day - haproxy had very low server/client timeouts
[14:53] <jamespage> I suspect nothing happened for a bit so it killed the connections
[16:19] <zul> smoser: ping
[16:19] <smoser> hey
[16:20] <zul> smoser: this is the dirty fix to get it going again http://paste.ubuntu.com/1658525/
[16:20] <zul> smoser: im coming up with a bit more elegant solution ;)
[16:22] <smoser> zul, is the issue that they're trying to use libvirt's mounting of disks ? as opposed to having nova set that up and providing libvirt with a path ?
[16:23] <sliddjur> How do I list a packages dependencies? ubuntu server 10
[16:23] <zul> smoser: thats the eventual goal i think
[16:25] <zul> smoser: but the disk doesnt get copied to the instances directory right now because mapping is an empty arrary because blockinfo.py doesnt understand lxc block devices (hint: there isnt any)
[16:27] <smoser> sliddjur, apt-get install --dry-run <package>
[16:27] <smoser> will give you a list of what it would install for you
[16:27] <smoser> apt-cache show <package>
[16:27] <smoser> will show you its immediate dependencies
[16:28] <sliddjur> smoser: apt-cache show package | grep Depends worked out well =)
[16:37] <zul> smoser: but one of the problems i see with lxc block devices is that the domain gets created before the images get created and keys are injected
[16:38] <smoser> well, we dont really care about injected keys.
[16:38] <smoser> but we will probably need files to come from somewhere
[17:03] <Eagleman> Is there being worked on a backport for libvirt 1.01+ ?
[17:06] <ivoks> jamespage: ive tried without haproxy; same thing :-/
[17:09] <iqualfragile> the ubuntu serverguide suggests using only ldap for authentification, is it safe to do so? (instead of using kerberos)
[17:11] <iqualfragile> well, i guess not
[17:11] <iqualfragile> but i like the idea of kerberos, will use it anyways
[17:26] <jamespage> ivoks, same problem with horizon right?
[18:28] <keithzg_> Rather random question, I'm using s3cmd to sync some backups and on every file I get "WARNING: path/to/file: Owner groupname not known. Storing GID-3342 instead." I'm inexperienced enough with S3 that I really don't know what that implies (otherwise the backups seem fine).
[18:30] <NewNewb> Good evening/day/morning! Ive got issues with a game server running on ubuntu through wine. Problem is, I cannot connect to my game server - and I have no clue how to do error searching. Ideas?`
[18:31] <sarnold> NewNewb: is the game server hosted on a different network than the clients trying to connect?
[18:32] <NewNewb> Its on my LAN. and connecting through local IP, nor external works(for my friends). The server itself shows up in the game's server browser
[18:33] <sarnold> NewNewb: are there any log entries in /var/log/ that look related?
[18:33] <sarnold> NewNewb: does wine preserve enough of windows to have the windows event log that might also have information from the game server?
[18:33] <NewNewb> I tried syslog, nothing at all. And I tried messages, also nothing, it just says "--MARK--" allt he time
[18:34] <sarnold> NewNewb: windows allows any process to bind to "low ports", < 1024 -- Linux does not. a process must be privileged to bind to a low port...
[18:34] <sarnold> that --MARK-- will become reassuring eventually :)
[18:34] <NewNewb> ports of relevance here are 7778, 7777, and 27015
[18:35] <Eagleman> Is there being worked on a backport for libvirt 1.01+ ?
[18:35] <NewNewb> 7777 being the port external connections come through. 7778 lists the server (i think) and 27015 is a steam port... no clue what that one does :)
[18:35] <sarnold> NewNewb: darn, there goes another potentially easy answer :)
[18:36] <NewNewb> haha, ive been hitting up forums and google for two weeks now. I just suck at linux - and dont know how to do proper error checking :(
[19:42] <aaa801> im running a java server (minecraft) in a screen session, every soo often the server goes down, when i open the screen session i find 19:28:19 [INFO] Unloading Player: Gremlin503
[19:42] <aaa801> >Killed
[19:42] <aaa801> root@ns3273339:/home/root/Voltz#
[19:42] <aaa801> Does that mean something on the box is killing the process ?
[19:42] <sarnold> is it always gremlin? :)
[19:43] <aaa801> no
[19:43] <aaa801> Out of memory: Kill process 14432 (java) score 859 or sacrifice child

[19:43] <aaa801> son of a..
[19:43] <aaa801> Welp i think i juts found the issue
[19:43] <sarnold> aha, you anticipated my next question :)
[19:44]  * aaa801 walks off in shame
[19:44] <sarnold> thgh, uh, one does wonder what java intended to do with 36 gigabytes of memory.
[19:45] <aaa801> i only had it assigned 30gb
[19:45] <aaa801> =/
[19:45] <aaa801> how it managed to even get hold of 36gb is odd
[19:46] <aaa801> im giving it 26g now
[19:47] <sarnold> aaa801: sorry.... it had allocated 36 gigs, but used 28 or so...
[19:47] <sarnold> is that expected for minecraft? o_O
[19:47] <aaa801> for this server ye
[19:47] <aaa801> 100 slots
[19:47] <aaa801> mc is terrible for memory management + java is too
[19:47] <sarnold> damn :)
[19:48] <aaa801> still not sure it had allocated 36 gig
[19:48] <aaa801> it was started with a max of 30g defined =/
[19:50] <sarnold> aaa801: well, virtual memory that was allocated by potentially never actually used...
[19:50] <sarnold> well, you can see the RSS there, it wasn't used.. :)
[19:50] <aaa801> then whyd it kill the process
[19:50] <aaa801> >_>
[19:50] <sarnold> aaa801: how much RAM does the machine have?
[19:50] <aaa801> 32gb
[19:51] <sarnold> aaa801: does it run anything else that might have taken up 4-odd gigs?
[19:51] <aaa801> shouldnt do, its got two ssd's in raid
[19:51] <aaa801> software raid
[19:52] <sarnold> aaa801: hrm. the kernel should normally only start killing things once it is in trouble.
[19:52] <aaa801> let me open up top
[19:52] <sarnold> aaa801: you could add some swap files ... dd to create them, mkswap to format them, then swapon to add them.
[19:53] <aaa801> http://i.imgur.com/MabnN78.png
[19:53] <aaa801> how is it managing to take up 31.6g
[19:53] <aaa801> when its limited to 26g
[19:53] <aaa801> -.-
[19:53] <aaa801> sarnold, any ideas?
[19:54] <sarnold> aaa801: well, right now it is only taking up ten gigs...
[19:54] <sarnold> aaa801: oooh
[19:54] <aaa801> oooh?
[19:55] <sarnold> aaa801: hrm, maybe 'oooh' in a bit.
[19:55] <aaa801> ._.
[19:55] <sarnold> aaa801: perhaps the 31 vs 26 is just 1000 vs 1024 nonsense?
[19:55] <aaa801> still shouldnt be that high when its on 26G
[19:55] <sarnold> no, 28g at the most if that were it...
[19:55] <sarnold> aaa801: okay, back to 'oooh'
[19:56] <sarnold> aaa801: if you don't want to add some swap space, you could tweak /proc/sys/vm/overcommit_memory or /proc/sys/vm/overcommit_ratio to force memory allocations by java to fail when the machine really has run out of memory
[19:56] <aaa801> swap space and ssds dont tend to mix too well
[19:57] <sarnold> aaa801: yeah, I know what you mean. but it might not be used too frequently..
[19:57] <sarnold> (you' have to chech with e.g. vmstat 1 once it is running again to find out)
[19:58] <sarnold> aaa801: you can find details on the proc files in the proc(5) manpage
[19:58] <aaa801> kk
[19:58] <sarnold> (sorry I left that out earlier. sigh :)
[20:03] <subman_> I have setup Munin according to the instructions found in the Ubuntu Server Guide and it works for the localhost only.  I don't seem to be able to see the data from the second server (munin-node).  Any ideas why this would be?
[20:25] <zul> smoser: https://review.openstack.org/#/c/22065/
[20:25] <yeats> subman_: check your syslog on the remote host to see if there are any messages from munin
[20:26] <yeats> I would also see if there's a way to run munin's daemon in a debug mode
[20:27] <smoser> zul could you put the trace in the bug ?
[20:27] <smoser> the one that is there now.
[20:27] <smoser> just for reference.
[20:27] <zul> smoser:  sure
[20:29] <smoser> https://review.openstack.org/#/c/22065/1/nova/virt/libvirt/blockinfo.py
[20:29] <smoser> it might be better to return None in line 119 there.
[20:30] <smoser> or maybe 'LXC'. the "" i'm afraid will just confuse things at some point.
[20:31] <subman_> yeats, thanks, it was a hostname issue.
[20:36] <smoser> zul, ^
[20:37] <zul> smoser:  good idea
[20:37] <zul> smoser: lets see what other people say as well I might be tied to the stake as well
[20:38] <smoser> i should put my comment in a review
[21:22] <ivoks> jamespage: yes
[21:57] <iqualfragile1> is there some way i (well not i but someone who does not now too much about computers) can manage users wich reside inside ldap and kerberos?
[22:18] <RyanLMul> Anyone run across an instance where 12.04 server stops communicating with DNS on another 12.04 intermittently?
[22:28] <RyanLMul> Hi there.  Anyone on here?
[22:29] <sarnold> RyanLMul: a few hundred .. I guess no one reading has seen what you've seen.
[22:37] <aaa801> Remember children 99.99999% of people in the irc channel are idle
