[00:43] hi guys [00:44] Im just about to reinstall ubuntu on my server [00:44] im wanting this time to have terminal serivces functionality [00:44] (like remote desktop) [00:44] (/freenx etc/vnc) [00:45] will installing via tha LTSP option be of any use to me? [00:45] i won't be connecting via LAN [00:45] i just want a dev desktop available via the net [00:46] sounds like you're wanting ubuntu desktop rather than ubuntu server then [00:46] oh [00:46] i don't just want to enable 1 instance of remote desktop tho [00:47] and i dont want to have X/gnome actually running on the server all the time [00:47] i just need it to auto start an x session on my remote login [00:47] sounds like you want vncserver i guess then [00:47] i see [00:48] do you know a decent tutorial for setting vnc up in this way? [00:48] iv always had trouble previously [00:50] anyone know where i download the code for the advanced tree to compile for xml-rpc? i'm tired of my large torrents displaying incorrectly. [00:50] does ubuntu impliment tightVNC ? [00:52] to both of you, i'm afraid i dont know, but google might [00:52] so if i'm copying a lot of data on my server from my ntfs drive to my new ext3 drive, what's the best method? just cp? [00:53] wo0f, it does vnc protocol which tightvnc is capable of connecting to... [00:53] but that doesn't really apply to ubuntu-server. [00:53] i use rsync for large transfer batches [00:53] i see [00:53] is there anything special to use rsync locally? [00:53] nope [00:54] just specify a local source and destination path [00:54] i personally use... [00:54] its just i dont want X to be running on the head of my server [00:54] rsync -aPv /local/source /local/dest [00:54] like rsync -va --progress /media/500GB/* /media/500_1 [00:54] i just want it to be invoked and used via network only [00:54] is the capital P --progress? [00:54] same thing, -P and --progress [00:54] d'oh [00:55] resumable, and you see progress reports, cp's too... quiet [00:55] yea [00:55] i've just had rsync fail for no reason before. [00:55] likewise, and with cp too [00:57] well now i have a massive amount of space [00:57] kinda weird having it all over in so many different partitions. [00:58] hmm, i guess problem is, i dont want to use vnc to connect too an existing screen, rather invoke a fresh x session on login [00:58] eh i don't want to try and coordinate that [00:58] wo0f, your server is running X? [00:58] vncserver will let you do that wo0f [00:58] cool [00:58] google it, test it locally / in a vm if needbe [00:58] it's fairly straightforward [00:59] x11vnc will allow you to view their current session _and_ uses better compression (imho) [00:59] Deeps: n1 [00:59] arrrghhh: he wants to connect and start an x session, not connect to a running session [00:59] what about NX, is this worth looking into as an alternative? [00:59] ie, he logs off, x goes with him [00:59] nx is sweet [00:59] but i had issues setting it up [00:59] haven't used it personally, no idea [01:00] i got it to work eventually, and it was like being there [01:00] i remain of the opinion that servers shouldn't need more than a command line ;) [01:00] well if i wont [01:00] i still want it headless [01:00] just serve up remote X [01:00] servers = no X [01:01] hmm [01:01] and you can forward X apps over ssh... [01:01] no need for vnc, nx, etc [01:01] yeah? [01:01] how do you do that? [01:01] ssh -X [01:01] well ssh -X user@server [01:01] assuming you use the default port etc [01:02] yea then from a command line run like "firefox &" - firefox will popup on your screen! [01:02] technology has been in unix since like 1984 lol. m$ still isn't capable of it (to my knowledge) [01:02] urr, you just run a win32 X server [01:02] well [01:02] XMing or some such [01:03] that's not from microshite [01:03] well i assume you have to be running a nix os for that to actually work [01:03] i use xmming at work since all our workstations are winblows [01:03] no, so? most packages in ubuntu repos aren't written by canonical [01:03] i said unix has had the technology since _x_ [01:03] and m$ still hasn't implemented it [01:03] ms has rdp [01:03] xmming + putty is not from microshaft [01:03] (i mean, im chatting to via putty:P) [01:04] but that's not an individual application [01:04] wo0f: http://www.math.umn.edu/systems_guide/putty_xwin32.html [01:04] Deeps: oo [01:04] Deeps: (Y) [01:04] change the relevant variables for your servers, rather than the umn.edu servers [01:04] you can't forward an individual application over the internet thru a secure tunnel. [01:05] no, but you can still forward an entire desktop that'll be more responsive and require less bw with RDP than you get from forwarding a single X application [01:05] (in my experience) [01:06] i honestly haven't compared b/w usage between the two. [01:06] X forwarding on a high latency low speed link is a very very painful process. not half as bad over RDP [01:06] yea the compression isn't there w/ssh./ [01:07] i read something about NX making things faster in both camps, but i've yet to play with it as thankfully I dont have to deal with remote guis anymore [01:07] this is whats tempting me towards nx [01:07] nx is seriously like being at the machine [01:07] it's ridiculous [01:07] well you can run rdp, x and vnc all through nx, which is nice [01:08] i think nx runs as one user [01:08] yea [01:08] i don't know if nx runs as one user or not... [01:08] so you have a separate accounts list just for nx [01:08] it probably does. [01:08] rather than running as the user your logged in as, like vnc [01:09] wo0f, there's a lot of options, it's linux haha [01:09] haha [01:09] sometimes too many for my liking/understanding [01:09] given that you can run x, vnc, or rdp through nx, chances are it's a case of how you configure it [01:09] mm [01:10] so whats LTSP [01:10] freedom of choice, it's great [01:10] ? [01:10] thin client manager i believe [01:10] so it doesnt use vnc at all? [01:10] run LTSP on a powerful server [01:11] run a bunch of underpowered dumb screens that simply connect to the server and accept local inputs, and display X forwarded from the server [01:11] slightly overkill for what you're looking to do i think [01:12] it just seems appealing as theres a install option on the disk in 8.10 now [01:12] it's been an option for installing for a while, i think it was restricted to edubuntu before though [01:22] is bitshift obsolete? [01:24] i don't know what bitshift is [01:24] is bitshift obsolete? [01:24] oops sry [01:25] for hard drives [01:25] as opposed to LBA [01:25] (logical block addressing) [01:27] yea still don't know what bitshift is [01:41] having a server harddrive setup like this : /boot and / on /dev/sda and /home on /dev/sdb, would i see a performance boost by using /home/ftp as a directory for files to be transfered from over /ftp on /dv/sda like it is now? [01:43] has anyone else tried installing 8.10 on a fakeraid raid 0 yet? it seems that it is only using 1 of my HDDs [01:46] fake raid and linux just don't mix [01:46] well, 8.10 is supposed to support it, so i figured i'd give it a shot [01:47] dmsetup status [01:47] nvidia_ecfbjcdh: 0 976773166 mirror 2 8:0 8:16 7453/7453 1 AA 1 core [01:47] are you wanting software raid, or fakeraid? [01:47] if fakeraid, have you checked your chipset is supported? [01:47] and iostat shows dm-0 and dm-1 being used when doing file transfers, but i see that sda is working, but sdb is sitting still [01:48] i am pretty sure it is supported, it installed fine... but where can i double check? [01:49] im not sure how youd check [01:49] i know suse supports raid out of the box [01:49] but i really shouldnt say that here :P [01:49] it's an nforce chipset, should be supported [01:50] im pritty sure the nvidia chipsets work [01:50] unlike the amd ones :/ [01:51] AMD has their own chipsets now? or do you mean the ATI ones? [01:51] i guess maybe AMD rebranded the ATI chipsets with their own name [02:01] hardware raid or nothing! [02:07] well, this is a somewhat budget file server for my own house [02:07] and the 1 pci-e slot has my eSATA card in it [02:08] yea i just built a budget file server [02:08] no raid... [02:08] yeh amd bought out ati [02:09] that they did [02:09] which will hopefully open the accelerated graphics drivers for the processors. [02:10] the graphics processors that is [02:55] anyone have experience setting up a pxe server? i'd love to be able to just plug machines in and boot the newest ubuntu w/o needing optical drives. i've already got nfs setup, and i have been struggling with tftp and dhcp. [02:56] i've wanted to play with it myself, but never had the reason to actually impliment it [02:56] i've been repairing a lot of computers lately so i'd love to have a pxe server [02:56] show the masses ubuntu [03:36] When using the inadyn DNS dynamic IP updater, should I use the root, or user crontab -e? [03:36] Using wget [03:38] If it doesn't need root permissions don't run it as root. That's pretty much the theory. [03:38] A dynamic DNS updated shouldn't. [03:38] k [03:39] Thanks dewd. :) [03:42] hads: Are you familiar with afraid.org's method of updating via wget? Would, 1-59 * * * * /usr/bin/wget http://freedns.afraid.org/dynamic/index.php?action=script&data_id=xxxxxx -o - >/dev/null 2>&1' >> /tmp/crontab work? [03:42] this doesn't really have much to do with my server, but i can't get my monitors at the right resolution & in separate X screens. twinview works tho... [03:42] J-_: No I'm not familiar [03:42] Okay cool, thanks anyway! [03:50] !info drupal hardy [03:50] Package drupal does not exist in hardy [03:50] * J-_ facepalms [03:50] !info drupal [03:50] Package drupal does not exist in intrepid [04:12] How can I enable mod_rewrite in apache2 in Hardy? [04:15] try a2enmod [04:18] mod_rewrite isn't in the most. [04:19] ? [04:22] a2enmod rewrite did it for me [04:22] Yah [04:27] hmm, not exactly sure what I ment to say. lol, I'm tired. [04:27] But I'll try that again [04:27] Is cl-url-rewrite the package I want to install/ enable? [04:27] No [04:28] hmm, it's already enabled. But, drupal is saying otherwise. [04:28] I think it's shipped with apache [04:28] Nevermind! It worked now. [04:29] I could have sworn it did before. [04:29] didn't* [04:29] Thanks again. [04:41] New bug: #294528 in postfix (main) "installing getlive crashed on wizard gui when pressing cancel" [Undecided,New] https://launchpad.net/bugs/294528 === Sindacious_ is now known as Sindacious [05:57] where is the apache root directory? [05:59] /var/www [06:00] thats what i thought. so, i have saved 2 files there how do i access them from the internet? [06:01] there is a redirection setup by default, you probably need to remove that... look in /etc/apache2/sites-available/default [06:02] I thought there was just an "It Works" page [06:05] it says that i dont have permission [06:14] deleted through terminal [06:27] i am trying to add a file to a folder with terminal. i used "sudo mkdir" to make the folder. how do i add to it? [06:50] josh_, man mv [06:50] josh_ touch filename [06:51] oh meant that way === kinnaz_ is now known as KiNnaZ [06:58] josh_: or cp if you just want to 'add' a file to that directory and not remove it from the old location [06:59] it would be easier to say, cp to copy file [06:59] mv to move file [06:59] rather to try to explain difference of cp and mv [07:33] $EDITOR my.file [08:11] moin [08:11] morning [08:54] I noticed tha tthe init script for policy kit doesn't actually do *anything* except upon 'start'. Anyone care to teach me a lesson? :) [08:58] Is it in the kernel? :o [09:00] How is this server related? [09:02] Well, it's running ubuntu server. I don't know how you have exactly defined "server specific" since the term is pretty loose. [09:03] Or am I only allowed to ask questions regarding topics in your serverguide (which is pretty much empty) ? [09:04] There's stuff in the server guide. [09:04] No, but policykit is a tool used on the desktop to achieve elevated privileges for discrete tasks. [09:05] It's not server related at all. [09:05] soren: Alright - I did not know that. I was forced to install it because console-kit-daemon kept giving me SEVERE logs about it. [09:05] "console-kit-daemon[6283]: CRITICAL: cannot initialize libpolkit [09:05] " [09:05] That's why I installed it and related packages. [09:06] I wonder why it gives a critical error about it if it isn't supposed to depend on it. [09:07] soren: So it's only server related if it's a base package in server? Or..? Please tell me where I would be more on-topic in that case. [09:07] ie, it's not server-related if I run server with additional packages then [09:07] :o [09:08] depends what the 'aditional packages' are [09:08] Gnome :) [09:08] its on topic if its server related - eg, services running on a server. not if its 'my desktop wont work on a server install' [09:09] I thought bloody policykit was a service. [09:09] this is 8.10 server edition. I only got policykit due to http://pulia.nu/tmp/console-kit-daemon these issues [09:10] Now again, console-kit-daemon did this out of the box - what is the *right* way to do then, if policykit is the wrong way? [09:12] ...I see. [09:12] Look... It's not that we don't want to help. It just way easier to ask desktop people if you're having trouble with desktop stuff. [09:13] YOU are telling me this is a desktop issue [09:13] I have *no* idea why you're telling me thart [09:13] that, sorry. [09:13] I am not running X, I don't have gnome installed, I don't even have a screen [09:14] This is ubuntu SERVER on a SERVER SERVING peoples homepages and shells. I just want to solve the problem at hand, being console-kit-daemon giving me critical errors in my log. I have no idea why it's even installed but I presumed it was "woven" into ubuntu for some reason [09:14] I'm terribly sorry, but policykit is simply not our domain. [09:14] What is that you don't understand? [09:14] 09:12:46 < soren> Look... It's not that we don't want to help. It just way easier to ask desktop people if you're having trouble with desktop stuff. [09:15] I don't understand why it's a desktop issue. [09:15] You have as of yet not explained that. [09:15] Look at policykit's description. [09:15] Ooo circles [09:15] It's not that hard. [09:15] soren: Yes, but let's *ignore* policykit for a minute. [09:15] gammy, you can `aptitude why $package` to find out what you installed that drew in policy kit as a dependancy (assuming you didnt manually install it ) [09:15] soren: And let's look at console-kit-daemon [09:15] ...which yells about policykit. [09:16] Yes. [09:16] Right? That's your problem, isn't it? [09:16] So the server component is whining about a desktop component [09:16] and you're telling me this is *not* a server issue? [09:16] Can't you just accept that the desktop guys are the guys who deal with consolekit and policykit? [09:16] you just told me desktop was "dealt with" by the desktop guys. you had not previously said so. [09:17] So now I know. [09:17] Thanks. [09:17] I .. guess. [09:17] Do you honestly think it's more useful if I just say "I don't know" instead of leading you to the right place to ask your questions? [09:17] Bloody hell! [09:17] 09:16:59 < gammy> you just told me desktop was "dealt with" by the desktop guys. you had not previously said so. [09:17] ??? Big surprises there. [09:17] Desktop guys deal with desktops. Who would have guessed? [09:18] Never would have guessed that. [09:18] No, how could you? [09:18] GUYS, guys... I'm trying to code, all this blinking is distracting me [09:18] * soren glances at his 381 irc windows and sends no sympathy to lukehasnoname [09:18] =) [09:19] let's hilight lukehasnoname a bit too! [09:19] lukehasnoname, hehe [09:19] so that lukehasnoname's coding would be more productive! [09:19] domas, but lukehasnoname might be struggling! [09:19] damnit [09:19] yeah, but if we don't hilight, lukehasnoname would stop coding! [09:20] domas, ah in that case i guess lukehasnoname better stay in converstaion :D [09:20] :-) [09:20] why can't 1/0 be defined [09:20] then I wouldn't have to handle that [09:21] lukehasnoname: It is defined. [09:21] lukehasnoname: It's \infty [09:22] new idea for a language function [09:23] Eh? [09:23] double IntegerOffset(int n) [09:23] returns a number VERY MINUTELY tweaked below or above n [09:24] double IntegerOffset(int n, bool upDown = 1) //0 is down, 1 is up [09:25] At any rate, 1/0 is defined. It's positive infinity. [09:25] infinity: Not you. [09:25] However, using that as an offset might not be defined. It depends. [09:25] so IntegerOffset(0, 1) would return 0.000000000000000000000000000000000000000000000000000000000000000001 or similar. I suppose I could define that as 0+Math.pow(1, pow(10,20)) [09:26] I'm writing a genetic algorithm whose fitness score is 1/radius of a circle [09:26] if that radius is calc'ed to 0, then I have to handle it [09:28] A circle can't have a radius of 0. [09:29] A circle is the set of points at a given distance from a given point. The set of points at 0 distance from a point is just the point itself. [09:29] rather, I'm calculating the max radius a circle can have, given a center and some parameters to meet [09:29] there are times that the parameters are not met and the max radius val is 0 [09:33] I have 8 hours to debug my algorithm, run tests on it, and write a one page paper about it for a test grade [09:34] if $rad=0; ; fi ? [09:37] if radius==0: [09:39] The zeros thing isn't trouble anymore, I don't think... it's something else now. [09:46] soren: you're not that good at math, are you? [09:46] soren: 1/0 is not infinity [09:47] the internet disagrees [09:47] http://lexlibertas.com/wordpress/wp-content/uploads/2008/04/i-divided-by-zero.jpg [09:47] Deeps: <3 [09:47] soren: http://en.wikipedia.org/wiki/Division_by_zero :) [09:55] domas: I just don't limit myself to real maths. [09:55] domas: I studied maths at university. I usually know what I'm talking about. [09:56] oh, wait, me too! :) [09:56] I wonder how you get the 'positive infinity' number [09:56] mathgeekfight [09:57] teeheeee [09:59] What else would it yield? [10:00] negative infinity, if you approach it with a limit :) [10:00] of course, if you define a concept of unsigned infinity, you can use it as much as you want [10:00] I don't like math [10:00] :( [10:02] Me neither. [10:02] Ironically :) [10:02] hehe [10:02] Abstract algebra is wicked cool. [10:03] Pretty much anything else, I really don't like very much. [10:03] math is applied philosophy :) [10:03] physics are applied math \o/ [10:03] some more nested applied sciences [10:03] and we end up building information systems :) [10:04] and sit in #ubuntu-server [10:04] haha [10:50] I'm trying to get a custom shell script to run when I insert a USB hard drive, so far I've installed autofs and "/etc/init.d/autofs status" returns this as the configured mountpoint: "/usr/sbin/automount --timeout=300 /media program /tmp/test.sh". But it doesn't work, any ideas? [12:43] nijaba http://www.securityfocus.com/bid/29106 :) [12:44] ah right, <52.. good we updated too hardy :) [13:15] what do I type to install LAMP on Ubuntu [13:16] tasksel [13:16] and select it from the list [13:17] do I do that at the term [13:18] yep [13:18] sudo tasksel [13:18] even [13:20] <_ruben> or sudo apt-get install lamp-server^ [13:23] thanks for your help [13:36] Does anyone have any experience with ivman? [13:39] I'm trying to get a script to run when an external USB hard drive is plugged in. So far I've tried usbmount, udev rules and now ivman. I've been watching /var/log/messages, USB drive is initiated as /dev/sdb but none of the daemons have worked and run my test script. Can someone help me? [13:40] jamey-uk: I'd use dbus and subscribe to DeviceAdded events from Hal. [13:40] I didn't know about ivman. It seems like it does kind of the same thing? [13:40] soren: yeah I think it must do. So I have to apt-get install dbus then? I don't understand, how/what is "subscribing" to the DeviceAdded event? [13:41] It's a dbus term. [13:41] DBUs has a notion of signals to which you can subscribe. [13:41] Hal emits DeviceAdded and DeviceRemoved signals when... Well, I imagine you can guess when :) [13:42] thanks, so how does Dbus relate to Hal, it's basically the bus that hal reports onto? [13:42] Pretty much. [13:42] How does ivman fail you? [13:42] I'm looking at its config now, and it seems to do what you want? [13:43] Better yet: What are you trying to do exactly? [13:43] yeah it does, none of the tools i've tried have worked which leads me to believe I've set something up wrong or haven't got a needed package [13:43] soren: thanks for asking :) [13:44] we've got a truecrypt encrypted drive, we want it to automount this external usb drive when you plug it in, but we don't want regular mount* stuff, we've got a command/shell script that will mount the drive for us. so far, when you plug it in dmesg says it's assigned to /dev/sdb. And we can succesfully mount it manually into somewhere like /media/usb-backup. [13:44] so now I just need *anything* to make a script run when a usb (hard drive) is plugged in. sounds simple, so far proved to be very tricky! [13:44] any help would be much appreciated :) [13:45] At the bottom of /etc/ivman/IvmConfigActions.xml... [13:45] there's a match-all snippet. [13:45] Do you see it? [13:45] It's uncommented right now. [13:47] erm, looking in that file, no 'match-all'...? [13:47] It doesn't say "match-all" [13:47] oh heh [13:47] 97 [13:47] ah gotcha "...Match name="*"' [13:47] yeah [13:47] The line just before that one says: \!-- [13:47] Er.. [13:47] comment delimiters, gotcha :P [13:48] and the line just below , which reads "-->" [13:48] Right. [13:48] /etc/init.d/ivman force-reload [13:48] Restart ivman (sudo /etc/init.d/ivman restart) [13:48] "Restarting ivman: manager.c:1387 (do_startup_configure) Directory /etc/ivman/ will be used for configuration files." [13:48] Yes, that should do it too.. [13:48] tail -f /tmp/devices [13:48] and try plugging something in [13:49] okay, here goes :P [13:50] *awesome*, it works :D [13:50] "usb_device_1058_702_5758485A3037303239313933 attached at Thu Nov 6 13:50:25 GMT 2008" [13:50] Ok. So ivman works :) [13:50] so..., how do I get it to run a script now? :) [13:50] fantastic, *nothing* has so far! [13:50] Look at the config file. [13:50] so an exec line [13:50] The part you just enabled runs a command line. [13:50] Right. [13:51] Just change that to point to your script. [13:51] what is "execun" vs exec [13:51] Probably unplug vs plug [13:51] I don't know, to be honest. [13:51] oh, der [13:51] :p [13:51] I've never used ivman. [13:51] yeah it is lol [13:52] okay so i'm going to tell it to run /tmp/test.sh, which is a simple bash script that echo's "Running script" then touch's /tmp/it-is-running (which I just rm'd) [13:52] Ok. [13:52] Here's a trick: === oly- is now known as oly [13:52] When the drive is plugged in, use lshal to find the name of the attribute you want to look for. === oly is now known as oly- [13:52] In your case, you want the one that tells you the name of the block devices. [13:53] Sorry, block device. Not plural. [13:53] okay let me just check this script works (because it hasn't yet) and then we can get onto lshal :) [13:54] Right. When you're comfortable that it works, run lshal, find your harddrive and pastebin that part that pertains to that. [13:57]
