[00:00] can someone please find me a guide on how to set up automount to a specified directory [00:00] i only need read only ability [00:01] no. you find a guide [00:01] oh well, i tried [00:01] time to load up google [00:01] how can i prevent ubuntu server 8.10 to turn of monitor after inactivity ? [00:02] press a key every few minutes [00:03] is that the only way ? [00:03] techsupport: Comment out DPMS line in xorg.conf [00:03] techsupport: of course it wasnt the only way... i just felt like being an idiot [00:04] Xperiment62, how often do you feel that way ? [00:05] genii, that'll require xorg installed no? [00:05] techsupport: quite often... its a bad habbit that ive picked up from linux support channels [00:05] Kamping_Kaiser: Heh, yes. Sorry, forgot was in -server for a minute :) [00:06] genii, so should i comment it out or no ? [00:07] genii, :) [00:07] techsupport: Do you have some gui installed? (Gnome/KDE/XFCE etc) ? [00:07] genii, nope [00:07] techsupport: Then no [00:08] so i cant turn that off ? [00:08] techsupport: There's probably still some way [00:10] I'd look whereever the ttys are configured. [00:11] it used to be inittab, but 8.10 doesnt have that. perhaps some upstart file? [00:11] techsupport: Perhaps -x /etc/acpi/screenblank.sh [00:11] (chmod) [00:12] that file looks like it relates to xorg, but give it a go [00:13] i dont get it , what do i do ? [00:13] -x ? [00:14] non executable [00:14] techsupport: No. Try this: sudo chmod -x /etc/acpi/screenblank.sh [00:15] genii, i dont have /etc/acpi/... [00:15] techsupport: Hm, OK. No other immediate ideas come to mind then [00:15] techsupport, tried running `apropos blank screen` ? i have a result called "setvesablank (8) - Turn VESA screen blanking on or off" that may or may not be useful to you [00:16] Kamping_Kaiser: Nice find [00:16] why does it say "The following packages have been left out" and lists linux-server/image? [00:17] genii, makes sense to see whats already available :) [00:17] hmmm [00:18] yays, it installed properly [00:20] Xperiment62: :) [00:22] nijaba: okay, i've merged screen-profiles [00:22] nijaba: i made a few adjustments [00:23] nijaba: i commented out the welcome screen from the default windows file, for the moment [00:23] nijaba: i hit a few problems with it that i'd like to get resolved first [00:23] nijaba: mainly, it doesn't look/work right on some window geometries [00:23] nijaba: also, i want to work on the keybindings a bit more [00:24] nijaba: i confirmed some of jdstrand's concerns [00:24] nijaba: i think we need to have a policy that a given keybinding must work in both a) gnome-terminal, and b) the console before we put it in keybindings/common [00:24] cxo: because those packages require additional new packages to be installed to perform the upgrade. after you've upgraded the rest of your packages, do a dist-upgrade and it'll show you what new packages it's installing to perform the upgrade [00:25] nijaba: i think we can add others to something like keybindings/xterm, keybindings/gnome-terminal, keybindings/konsole, keybindings/console and so forth [00:25] nijaba: if they only work in one place or another [00:25] nijaba: but i think if something lands in keybindings/common, it should be pretty portable [00:54] how do i set up automounting easily? [00:55] vorian: I'm sort of here now. Should be around in an hour or two. [00:56] ScottK: no problem, i pm'd you a link to look over [00:59] Xperiment62: fstab/autofs/pam_mount [01:27] how do you remove old kernels that are still on the system? [01:27] dpkg -r [01:28] aptitude remove [01:28] apt-get remove [01:31] how do i list the pkg names of all the kernels installed? [01:34] cxo: dpkg -l | grep linux-image [01:34] thanks a lot guys [01:35] i'm new to this apt/deb business [01:44] I have just installed a sata card in our server and need to hotswap drives with it... I found and installed the package scsiadd, but all of the scsi ID's say 0. [01:44] Is there a way to generate scsi ID [01:59] i get a message at boot from the 8139cp module saying that the hardware needs the 8139too driver instead, which after login is already loaded and ready to go, can i just blacklist 8139cp? why does it keep trying to load [02:00] Just blacklist it [02:02] i put it in /etc/modprobe.d/blacklist but it still loads it at bootup [02:03] Thanks mathiaz [02:05] jdstrand: nijaba: okay, updated screen-profiles uploaded to my ppa, and back onto the queue for universe [02:06] nijaba: we need to talk about the keybindings a bit more tomorrow [02:15] how do you get it to save the iptable rules? [02:23] maybe can anyone recommend me a VPS service provider in U.S. East ? [02:24] linode [02:24] hads: do they offer Ubuntu Server? [02:24] Yeah [02:25] linode rocks [02:27] hads: thanks [03:02] does anyone know of VPS provider around virginia or in virginia ? [03:52] Can I add disks to a RAID5 array? [03:52] As in, go from a 4disk raid5 to a 5 disk? [03:57] Yeah should be able to [04:00] http://linux-raid.osdl.org/index.php/Growing [04:07] wow [04:07] ZFS can't do that [04:09] ok i'm logged in into my new linode ubuntu 8.10 32 bit server, but nothing seems to work i guess all the packages are not installed? is it possible for me to update it with one command for it to be equivalent to an installation i would get from a regular ISO install ? [04:43] what's the way to restrict user UIDs being exposed to others? 'top' and 'ps' can be restricted on BSD systems by passing '0' to 'security.bsd.see_other_uids' in src/etc/sysctl.conf. what can be done for linux? [04:47] compengi: "exposed" ? [04:47] Oh, you don't want user to be able to see another user's uid? [04:47] Why's that? [04:47] to prevent harvesting? [04:48] to prevent them picking on each other :D [04:48] each user likes his privacy [04:49] i like root's too ;) [04:49] Give them each a virtual machine ;-) [04:49] nah.. [04:49] if this can be done simple as on bsd [04:57] compengi: Linux != BSD [04:57] reading forums about changing computer name, they say its in /etc/hostname but i dont have this file [04:58] techsupport, Then create it: it ought to exist. [04:58] techsupport: what happens if you type "hostname pancake" ? [04:59] ball, i know that for sure, that's why i'm asking around if there is a similar way on linux [04:59] compengi: fair enough. It's an unusual requirement though afaik. [05:00] techsupport, using ubuntu? [05:00] what is your hostname currently? [05:02] techsupport, yes ubuntu [05:02] blahnana, ubuntu [05:02] and what do you get if you type "hostname" [05:02] by itself [05:02] it should output the current hostname [05:03] unless you typed 'hostname pancake' already [05:04] I like pancakes :-9 [05:04] ...even American ones [05:08] mmmmm pancakes [05:08] see?! [05:10] ;) [05:10] when i type screen i get error Cannot open your terminal '/dev/pts/0' - please check. [05:10] techsupport: then don't type "screen" [05:11] why not? i need it [05:11] Oh. [05:15] sounds like you might be using su [05:15] or at least, that's one common cause [05:16] blahnana, thanx, let me try to logout [05:16] if you use su, make sure you use something like su - [05:17] perfect [05:17] worked [05:17] or sudo [05:17] Or launch screen, and use su inside the screen session. Running screen as root can be dangerous. [05:19] another thing [05:19] paul@linode:/$ sudo chown orudie /home/orudie [05:19] sudo: unable to resolve host linode [05:20] i recently changed hostname by 'sudo hostname linode' [05:20] that just changes an environment variable I think [05:20] you haven't changed your hostname [05:20] not sure if hostname actually does anything else [05:21] looks like it does, but clearly the change hasn't stuck [05:21] blahnana, but how can i change the hostname? [05:21] you need to put your hostname in /etc/hostname [05:21] echo 'linode' > /etc/hostname [05:21] reboot and check it comes up with the correct hostname [05:21] persia, I'm not sure if either is better than the other actually [05:21] /etc/hostname does not exist [05:22] techsupport, The command above will replace it. [05:22] (or create it if it doesn't exist) [05:22] if screen is vulnerable, you could get control of root's screen [05:22] and have a root login [05:23] but if screen is vulnerable, you could get control of a user's screen, and still have a root login [05:23] just did echo 'linode' > /etc/hostname , and /etc/hostname still doesnt exist should i create it ? [05:23] I think the issues with screen tie back to old issues with it [05:23] blahnana, At a deep level, it matters, because one might not be using "files" to determine the hostname, and there are various ways to tweak things. /etc/hostname is used at boot to run hostname. After running hostname, one often needs to reinitialise sessions and services to use the new hostname, as they may only run gethostbyname() at startup. [05:23] techsupport, did you run it as root? [05:23] blahnana, yes [05:23] techsupport, echo linode | sudo tee /etc/hostname [05:23] techsupport: "sudo echo 'linode'>/etc/hostname" [05:23] ? [05:24] ah, what persia said [05:24] ball, Won't work, because the redirect doesn't inherit sudo. [05:24] persia: thanks, good point. I'm not used to sudo [05:24] if I use it, it tends to be "sudo su" [05:24] oops [05:24] ball, It's *much* safer: definitely worth playing about with. [05:24] "sudo /bin/sh" [05:24] persia, I meant "I'm not sure if one is better than other... running screen as root or running screen and then opening a root shell" [05:25] ball: 'sudo -i' is the nicest way to do that [05:25] persia: I usually live somewhere sudo doesn't exist [05:25] jtaji: thanks [05:25] still dont exist [05:25] sudo -i seems better to me than sudo su [05:26] I meant "sudo sh", "su" was a typo [05:26] but, that's still handy to know why there are limitation with changing the hostname on the fly [05:26] so if i create it , what do i put in /etc/hostname ? [05:26] blahnana, running screen and then running programs as root is safer than running screen as root, because there's no possibility to attach directly to the root process from arbitrary input: it is mitigated by screen (which doesn't have a lot of security, but that's a separate thing). [05:27] root@linode:/# echo linode | sudo tee /etc/hostname [05:27] sudo: unable to resolve host linode [05:27] linode [05:27] root@linode:/# [05:27] techsupport: you need to edit /etc/hosts also [05:27] or you break sudo [05:27] persia, not sure what you mean [05:28] blahnana, Right. screen can spawn stuff, so if you're running screen, I can attach to your screen (yes, screen allows sharing), and spawn another shell, and do stuff, and detach, without you seeing it. [05:29] If you're not running screen as root, I can't get root by doing this: only access to your user stuff. I'd have to switch to control of your root shell, which I hope you only have open when you're actively doing stuff. [05:29] jtaji, sorry i never edited /etc/hosts what should i change there ? [05:29] Also, since screen supports multiple sessions, if one doesn't run screen as root, one can run a mix of root and non-root processes from screen. [05:29] we were weighing up the merits of one vs the other though [05:29] what modes does /etc/hostname need? [05:29] 644? [05:30] I suppose there's no need to hide it [05:30] jtaji, http://pastebin.com/m67e848de this is my /etc/hosts [05:30] so you'll know that there's a root shell [05:30] techsupport: second line should be something like 'xxx.xxx.xxx.xxx foo.domain.tld foo' [05:30] where xxx.xxx.... is your external IP [05:30] there's a great chance that you'll have access to my user screen anyway [05:30] it's more likely I might have used the password in an insecure way [05:30] whereas my root password will be more protected [05:31] most likely [05:31] so change 127.0.0.1 localhost to 207.192.72.15 linode ? [05:32] no leave that line [05:32] alone [05:32] Right, and if you're careful, you'll run a user shell, spawn root when you need it, and go back to user before you leave the shell unattended and detach. [05:32] haha [05:32] i'm a noob [05:32] well, I feel that we weren't talking about that [05:33] techsupport: http://www.linode.com/wiki/index.php/Configure_Static_IP [05:33] I agree with your point, but I think we're getting into operating procedure, which I perhaps assumed was beyond the scope of the initial comments [05:34] whereby I assumed that if you a) must have a root shell and b) must run screen you have already considered the things you're pointing out [05:34] OK. Then sticking strictly to screen, aside from operating procedures, there's also that it's easier to run a mix of root and non-root programs from a screen session if screen itself isn't running as root. [05:35] maybe, maybe not... if I'm running root screens I'd rather keep them together protected [05:35] And it's easier to establish operating procedures with redundant logs for mandatory unattended long-running root shells. [05:35] and not have a user having access to them necessarily [05:35] Personal preference, I suppose. Wouldn't be my recommendation. [05:35] lessens the chance that I do something stupid with my terminal [05:36] and I'd use my gui to split up the sets of terminals [05:36] yeah, personal preference [05:36] ok fixed [05:36] I think that if you're running root shells, and you've got them in a screen, I see it as better that you're running the screen as root in the first place [05:37] also, when i do logout it returns [05:37] paul@linode:/$ logout [05:37] bash: logout: not login shell: use `exit' [05:38] but in terms of which is more vulnerable... I wondered if there was a code reason for what you suggested, rather than just best practices type thing [05:38] techsupport: that's correct, use exit or ctrl+D [05:39] blahnana, Not code, just principle of least-privilege. [05:39] realistically, I'd think that your normal user account is more likely to be broken through running naughty things, or needed things that have bugs [05:40] I think that principle doesn't hold true when you're protecting a mechanism for full privileges behind a lower-privelege thing [05:46] blahnana, i archived a directory with tar -cvzf , but how can i extract it now ? [05:47] use x instead of c [05:47] use t instead of x or c if you want to see a list of files in the archive [05:48] tar -xvzf q2server.tar.gz [05:48] returns no such file or derictory error exit delay from previouse errors [05:49] blahnana, ping [05:49] is there a file called that? [05:49] in the current directory? [05:49] orudie@linode:~$ ls [05:49] q2server.tar.gz [05:49] orudie@linode:~$ tar -xvzf q2server.tar.gz [05:50] yes [05:50] try gzip -d q2server.tar.gz [05:50] does that work? [05:52] needed permissions [05:52] :) [05:52] ls [05:58] hello Techie, owh [05:58] sup dude [06:00] not much [06:00] yourself?

[10:32] Well, not "apparantly", but "probably". [10:33] soren, ok [10:34] although i did not understand [10:35] Well, it might be something different.

Guide i am looking at show to use mt-st... is this correct? === Shoopuf1 is now known as Shoopuf === Brimstar1 is now known as Brimstar [12:55] I installed a HighPoint 4 port sata card in our server last night, is there a way to make the drives hot swappable? [12:57] i doubt hpt is capable of hot swap [12:57] that's a 10$ raid controller, right? [12:59] It was like $200 [13:00] I found the scsiadd program and it works to remove sda, but that's it [13:00] 200$ for hpt? [13:00] last time i buyed hpt, it was very cheap :) [13:01] doing scsiadd -p to see the list; the list states all scsi drives are ID: 00 [13:01] there are like 10 diff models [13:01] hot swap should be supported by controler [13:01] i don't think you could do anything with controller that doesn't support that [13:02] hot swap = OS isn't aware of missing disks [13:02] so it doesn't know when it is out and back in again [13:02] but i could be wrong :) [13:03] ivoks, scsiadd -s rescans for scsi devices and adds them [13:03] scsiadd -r 0 will remove the 1st device [13:04] scsiadd -r 1 should remove the second, but all the ID's are 0, so I do not know how to, or if I can, assign ID's to the scsi drives [13:05] well, if you are using raid controller, you should see only one drive, right? [13:05] scsiadd is for adding/removing scsi devices [13:05] logical raid disk should be one device [13:06] so, if you have non-raid scsi controller that supports hot swap, you would use this tool [13:06] i'm not sure this should (or is designed to) work with raid controllers [13:06] The card has 4 ports with drives in each. The goal is to run 2 mirrored with mdadm, and 2 as singles for removable backup [13:07] ah... mdadm raid, not hardware raid [13:07] yes, I like the idea of being able to move the raid drives to another machine in case of problems [13:07] no controller required... The only reason for the card is to use the sata ports [13:08] well, still, controller should support hot swap [13:09] (i never used scsiadd) [13:09] i'm just reading this: [13:09] This is *NOT* a substitute for powering down to connect or disconnect hardware unless it's specifically designed to be hot swappable. [13:10] hi, i have a problem in choosing a virtualization technology. I'd like to go with kvm as i think it is the choice for the future, but in the few time i had for testing I noticed a consistent performance difference with xen. Probably it is only because of my configs, but i have too choose and have no more time for investigating. Can i have your points? [13:10] i always use kvm, when i'm not using vmware [13:10] recently, i droped vmware for kvm [13:11] ivoks, from HighPoint description: Hot swap and hot spare [13:11] ivoks: what about vm process cpu usage? [13:11] eolo999: vm uses cpu depending on what you are doing in vm :) [13:12] heath|work: then, hot swap should work :) [13:12] ivoks: when idle still my kvm machine was using ~= 20 % of Host CPU! [13:14] eolo999: mine uses 0-1 when idle [13:14] ****! [13:14] so it seems it's MY problem.
