Demon_Jesterit has multiple gpilu im plugged into the front. back is probably default00:02
TJ-That would explain it!00:02
Demon_Jesterstill nothing on back plug. as long as i can ssh im find.00:05
TJ-yes. check "/var/log/dmesg" for clues as to which GPU/head has been selected as the primary00:06
TJ-All my servers are on remote network KVM so I always ensure the heads are connected correctly00:06
Demon_Jestergreat now to see why ssh isnt working.00:06
Demon_Jesterone more question since i made a new account i dont have a home directory would that cause any problems when installing packages?00:13
tmontneyAnyone able to assist me with a postfix/dovecot issue?00:14
TJ-Demon_Jester: A home directory is usually created automatically, if you use "adduser"00:15

neonixcoderWhat is the best way to upgrade a production headless server remotely?05:23
neonixcoderI am planing to upgrade from 10.04 to 14.04, which will be in two steps 10.04 to 12.04 then from 12.04 to 14.0405:23
neonixcoderany suggestions?  As I tried to upgrade my machine with "do-release-upgrade -f DistUpgradeViewNonInteractive" but no positive result..05:24
tonyyarussoneonixcoder: I've never used the -f option before.  Ideally you have some sort of management console access, but I've done it just via SSH before.05:46
neonixcoderThanks for the reply tonyyarusso05:46
neonixcoderThe problem is I will not have console access as these machines are located remotely and can be accessed via 3G only..05:47
tonyyarusso3G only huh?  That's a bit special.05:48
tonyyarussoHow far is the drive if they don't come back up?05:49
neonixcoderyes..05:49
neonixcoderIt depends.. we even have some stuff in middle of Aus desserts which are like 3000km from Sydney :(05:50
tonyyarussonice05:50
neonixcoderWhich are connected with 3G or just Satlink to connect and remote manage..05:51
tonyyarussoFurthest I've had to drive for physical access was about 2 hours - kind of a fun day actually.05:51
neonixcoderyes..05:51
tonyyarussoOh, one thing I will say - run the upgrade process inside of screen, so if your SSH connection drops you can reconnect.05:53
neonixcodertonyyarusso: Is there any tool before upgrade can we just emulate changes and see if something may go wrong after upgrade?05:53
tonyyarussoNot that I know of - for that depth of check you have to try upgrading an identical test system.05:53
neonixcodertonyyarusso: I tried screen, but somehow once the system reboots, it struck up at kernel panic..05:54
neonixcoderright now trying in a lab machine before moving to prod..05:55
neonixcoderbut non getting success..05:55

StuxnetHi all. Newbie here. Simple question. If you use wget to download a tar.gz file because it's not available as a package from the repositories it installs with "python setup.py install" how are you supposed to uninstall it? Not able to find any kidn of uninstall script.15:43
StuxnetThe program in question is DenyHosts-2.5 (old one I know that is why I wish to remove and install the latest which I think will be installed under different names/directories)15:43
lordievaderStuxnet: If it's available in pip, pip has am uninstall command.15:44

roracleokay guys, i'm already running Concrete5 on my apache server, BUT UBUNTU APACHE is SO different, I have ZERO clue how to set up another virtual site19:11
roraclei'm editing sites-enabled/default-ssl.conf is that right?19:12
tewardroracle: no, you edit sites-available/default-ssl.conf if you're adding a new site to that config.  BUt the correct thing to do is make a separate site configuration in sites-available19:12
tewardmake that VirtualHost block, etc.19:12
tewardthen a2ensite TheNewconfig.conf19:13
roracleokay there's either default or 00019:13
teward(I think(19:13
tewardroracle: so create a new one?19:13
roraclewell 000 has port 80 for my default port while "default" has some god awful port number19:13
tewardroracle: you're wanting to create a whole new site that your server can serve?19:15
tewardi.e. NOT what's already present19:15
roracleteward: yes19:16
tewardthen don't use the existing configuration files19:16
tewardat all19:16
tewardcreate a brand new one19:16
tewardput the configuration in that19:17
tewarda2ensite that new configuration file19:17
roraclei don't get it... why when Apache is heavily documented that Ubuntu decided to change it all up?19:17
roraclei don't understand what a2ensite means19:17
TJ-roracle: See https://help.ubuntu.com/14.04/serverguide/httpd.html19:17
* teward rolls eyes19:17
roracleyes, i suck at this, sorry i am more inclined to game development, yes it's my fault lol19:18
tewarda2ensite is a utility script/command19:18
teward`man a2ensite`19:18
tewardhttp://manpages.ubuntu.com/manpages/trusty/en/man8/a2ensite.8.html19:18
geniiProbably also: man a2enmod19:18
tewardthat as well19:18
tewardfor enabling/disabling Apache modules (such as SSL)19:19
roracleomg this is nuts19:19
tewardno it's really not19:19
tewardit's a different dynamic of thinking than that of a software developer19:20
roraclei might end up not using ubuntu in the end because i got used to all the documentatino i read on apache, then found out all of it was wrong, and now i'm totally confused on what to do and have to keep reminding myself that i have to look it up since it's not what i learned intiially19:20
tewardwhat documentation did you even look a19:20
tewardt19:20
tewardyou haven't stated which documentation you're using19:20
roracleapache's doc19:20
tewardWHICH doc from Apache19:20
tewardthey have about two billion docs19:20
tewardplus different versions of apache's documentation19:20
roracleyes, the ones for apache2 httpd, i didn't realize it was that big of a difference19:21
sarnoldall the apache docs I'm familiar with discuss directives and options, not configuration layouts19:21
roracleapparently they have this "httpd.conf" file that should be edited.  then i find out in ubuntu, it's allllll split up19:21
roracleso what did make sense doesn't now19:21
patdk-wkheh?19:21
patdk-wkno one has a single httpd.conf unless your using apache from source19:22
teward^ that19:22
tewardquite literally that19:22
TJ-roracle: The rationale is from Debian; the idea is that if you confine your own site's directives to your own files in the /etc/apache2/*-available/ directories, and use a2{en,dis}{site,mod,conf} tools to create/remove symbolic links in /etc/apache2/*-enabled/ directories, then any changes to the Debian/Ubuntu distributed packages will not over-write change any of your own site's custom settings.19:22
sarnoldthere's a huge difference between the apache 2.2 that shipped in 12.04 LTS and the 2.4 that shipped in 14.04 LTS, thuogh, is that the source of your confusion?19:22
tewardsarnold: he's confused about file layouts19:22
tewardsarnold: i.e. "wtf do i do to add a new site host block"19:22
patdk-wkhe is upset that *insert tutorial here* does not work directly19:22
teward^ that too19:22
patdk-wkcause it's specific to apache, and not debian/ubuntu19:22
roraclemaybe19:22
tewardroracle: the ONLY DIFFERENCE between Apache's source documentation for adding a new server block19:23
tewardand Ubuntu/Debian's handling of it19:23
tewardis that you put your individual site VirtualHost blocks into a different file19:23
patdk-wkif you want, ubunt still supports one large httpd.conf if you use it19:23
roracleokay well what do i TYPE exactly then?19:23
tewardand use the utility script to symlink it to sites-enabled/somefilenamehere19:23
patdk-wkit is normally an empty file, but you can fill it up19:23
tewardroracle: YourTextEditorHere /etc/apache2/sites-available/MySite.conf19:23
tewardreplace YourTextEditorHere with your given text editor19:24
tewardand MySite.conf with something more descriptive (but keep .conf at the end)19:24
roraclei'm not here to learn perse, but i learn by DOING and it's like I learned 1+1=2 and now it's like everyone is saying 1+1=3 and it's really a mind messer19:24
roracleokay19:24
TJ-roracle: If you were to directly edit the configuration files that the apache2 Debian/Ubuntu packages ship then any updates (think security) would require administrator intervention to merge any changes in those config files if they conflict with the site-specific changes19:24
tewardif you aren't going to listen to me trying to help you right now i'll go back to squishing server bugs19:24
JanCroracle: Debian/Ubuntu-specific Apache setup is documented in /usr/share/doc/apache2/README.Debian.gz19:24
teward(which is actually less painful than end-user support.)19:24
roracleno teward it's that everyone is saying stuff to me19:24
tewardroracle: then learn to ignore people.  focus on one thing at a time19:25
tewardroracle: the problem with IRC chat is it's easy to get overwhelmed, so what you need to do is focus19:25
roracleokay so each site will have a different conf file, and i need a new one made, NOT add a block to existing ones?19:25
tewardroracle: correct.19:25
TJ-roracle: Correct :)19:25
tewardroracle: so you can very easily disable one site without having to manually find and remove the configuration directives19:26
tewardroracle: once you've followed that command, you've got an empty file.  Put your configuration directives for the VirtualHost blocks there.19:26
JanCroracle: and you really should always read README.Debian for packages that have it  :)19:26
roracleokay see the Apache docs had me adding to the file which confused me19:26
tewardroracle: that's the FromSource method19:26
tewardroracle: the only difference is we have a different definition of where the site configurations go.  It's actually to help improve the friendliness of administration19:26
roracleyeah, i just never realized each distro was going to be so very different.  you don't expect a calculator to rearrange the numbers, ya know?19:26
roracleyeah i see that now19:27
TJ-roracle: FYI something else that might trip you up later is that in Debian/Ubuntu the executable (running process) name is "apache2" not "httpd"19:27
roraclewell i'm in Ubuntu and it's running as apache219:27
sarnoldroracle: heh, have you compared a phone versus a calculator lately? :)19:27
tewardroracle: to continue what i was saying: after you've added the configuration to the MySite.conf or w/e you named it, save the file.  Then run `sudo a2ensite MySite.conf`19:27
roracleokay cool19:27
roraclebrb19:27
patdk-wksarnold, my phones no longer even have numbers19:27
tewardthen run `sudo service apache2 reload`.  Your site *should* then come up19:27
tewardprovided you have the modules you need enabled19:27
sarnoldpatdk-wk: hehe :)19:28
tewardsarnold: even with calculators - the internal coding is widely different in terms of code style, etc.19:28
tewardincluding fluff19:28
patdk-wkare we talking rpn?19:28
* teward shrugs19:28
sarnoldteward: please don't get me down a calculator nostalgia rathole, I've already been down the orbital mechanics rathole today..19:28
tewardIn Other News: landscape-client should not run on anything with less than 256MB RAM19:28
roracleokay i made the file, do i need to change perms on it or anything?19:29
roraclebecause it doesn't see the file there at all19:29
roraclebut it is19:29
tewardroracle: ls -al /etc/apache2/sites-available19:29
patdk-wkdid you link it? a2ensite19:29
patdk-wkI think that is the command :)19:29
JanCand you need to reload apache19:29
tewardroracle: did you also run `sudo a2ensite FooBarBaz.conf`, then do `sudo service apache2 reload`, like I said19:29
roracleokay i just made the file, haven't run a2ensite because when i did it says it's not there, though it is19:29
tewardand yes i just throw random stuff in for filenames that i don't know what they really are :)19:30
tewardroracle: is it in /etc/apache2/sites-available19:30
tewardor in sites-enabled19:30
sarnoldroracle: make sure the .conf is there -- the scripts look for that.19:30
roracleyes sites-enabled19:30
roracleand it's a conf file19:30
tewardroracle: don't put it there19:30
roraclei called it "blog.conf"19:30
roracleoh?19:30
tewardroracle: sudo mv /etc/apache2/sites-enabled/blog.conf /etc/apache2/sites-available/blog.conf19:31
tewardit goes in sites-available, not sites-enabled19:31
tewardthen run the `sudo a2ensite blog.conf` and `sudo service apache2 reload` commands19:31
tewardroracle: the a2ensite and a2dissite scripts are designed such that your config never really leaves sites-available, and is linked into sites-enabled19:31
tewardspecifically that when you reload the configurations with `sudo service apache2 reload` you don't have to remove the config file from disk and move it to somewhere else on disk19:32
roracleokay19:32
roraclei just ran it all, now what?19:32
roraclerestared and everything19:32
roracleand it's not working19:32
tewardroracle: go to the domain you set in the virtualhost block19:32
roraclei told it blog.ghostlightgames.com19:32
roracleand i go there and nothing19:32
tewardroracle: does that domain point to your site/server's IP address?19:33
roracleyes19:33
roracleor it should19:33
roraclei can get to the main page19:33
roraclewww.ghostlightgames.com19:33
roracleit's the main page19:33
teward% dnsget -t ANY blog.ghostlightgames.com19:33
tewarddnsget: unable to lookup ANY record for blog.ghostlightgames.com: domain name does not exist19:33
roraclebut i'm trying to add blog.ghostlightgames.com19:33
tewardroracle: www.ghostlightgames.com probably resolves.  You need to add a DNS record for blog.ghostlightgames.com, wherever your dns is done19:33
roraclelike with godaddy?19:34
tewardor whoever does your DNs19:34
roracleyeah that's them19:34
tewardthen to there, add another DNS record, this time for blog.  not www or @, but blog.19:34
patdk-wkwithout the . :)19:34
tewardthen either a CNAME to ghostlightgames.com like your www. site has.  Or an A record.19:34
tewardCorrect.19:34
roracleokay19:35
tewardpatdk-wk: that was sentences though, because some of us actually care enough to type in full sentences :)19:35
patdk-wkyes, but expecially dns, it can cause breakage19:35
tewardpatdk-wk: that was sentences though, because some of us actually care enough to type in full sentences :)19:35
patdk-wkbut hopefully, that dns editing gui, wouldn't allow a dot in that location19:35
tewardoops19:35
tewardbut yes19:35
tewardpatdk-wk: indeed.  it gets tricky when you run your own DNS servers xD19:36
tewardthen you have to edit the zonefiles direct :P19:36
roracleso what do i do exactly now i'm logged into godaddy?19:36
roraclezonefiles?19:36

qhartmanAnyone have any recommendations for an inexpensive temperature monitoring device that integrates well with nagios? Ideally I'd like something that has support for a few remote sensors20:06
qhartmanEverything I've found so far is either major overkill, or isn't really quite enough. Having a hard time finding "jsut right".20:07
patdk-wkipmi works well20:08
qhartmantrue, and I have some quick and dirty scripts that watch that for the internal server temps, but I'd like to know ambient in a couple places in the room, as well as the supply temp from the air handler20:10
qhartmanSo I can catch things earlier20:10
qhartmanIn typical IRC fashion, as soon as I asked my question I hit upon something that looks liek a good solution: http://www.itwatchdogs.com/climate-monitor-watchdog-100-p67.html20:15
tewardqhartman: hate to say an arduino, but...20:17
tewardprobably nothing 'inexpensive' if you want it to report back20:17
teward(we have three arduinos at different spots in a server room to monitor temps...)20:18
qhartmanyeah, I'd be happy to roll my own if I weren't spread so thin already, but as it is, paying a bit for something that works OOB is worth it.20:18
qhartmanteward, I'd be glad to learn more about your setups though if you have references you could point me to.20:19
tewardqhartman: i didn't set them up, sorry20:19
tewardi know they're in the room, I don't know who built em up or configured em20:19
qhartmanwomp womp. Thanks though20:20
TJ-They're quite a few USB temperature sensors that present on a ttyUSB* interface20:21
TJ-s/They're/There are/20:21
TJ-Instead of the optional temp/humidity sensors for my Server Technology CDUs I used this:  http://www.dlpdesign.com/usb/th1.shtml20:23
qhartmanNeat. Though, at $90 each, it's nearly the cost of the stand-alone unit I linked above with the number of locations I want to monitor.20:24
qhartman$430 vs $36020:25
TJ-Yeah... there are multi-channel alternatives, but I only need to monitor 2 cabinets20:25
qhartmanright20:26
qhartmanthanks for the suggestion though20:26
qhartmangood device to know about20:26
sarnoldI've long wanted a reason to try out ibutton / 1-wire devices20:26
qhartmanthat would be fun20:27
TJ-qhartman: This is another I found after I'd bought, and integrates woth nagios: http://www.finnie.org/2010/03/07/external-temperature-monitoring-with-linux/20:28
