[00:35] <keithzg> Hrmm. I'm a bit surprised there's no easy way to tell what files are missing chunks due to bad sectors from a ddrescue .img and .log. Guess I was hoping to be lazy!
[00:36] <sarnold> keithzg: heh, that seem slike the whole point of having a .log file :)
[00:36] <sarnold> keithzg: check for strings of 512 or more zero bytes perhaps?
[00:40] <keithzg> sarnold: I didn't actually run ddrescue with any fill setting, so as far as I understand it just skips bad sectors, then.
[00:41] <keithzg> The suggested way seems to be to md5sum every file and then run again with filling in missing data and then md5sum *that*, which seems . . . inelegant.
[00:43] <keithzg> I just naively assumed these details would be in the log file, which was indeed naive of me since ddrescue itself uses the log file as a reference (for repeated passes on failed sectors).
[00:55] <keithzg> The main problem is the literally millions of files in question here, so . . . this is going to take a while. Alas!
[00:57] <sarnold> and if you have md5sum executions waiting on dead blocks in files that might take even longer
[01:30] <keithzg> Well, I'm running it on the image file created via ddrescue, so that *shouldn't* be a problem, unless I'm being braindead and missing something.
[01:30] <keithzg> Actually yeah, when I think about it more I don't know why I'm so certain of that, heh.
[01:31] <keithzg> But so far it's going through files quite quickly, there's just a huge ton of files.
[01:38] <genewitch> How good is ubuntu server? Running on old Xeons, in a VM, with only 600MB of memory, it took me 2 years to finally need more memory. Started hitting swap last week, upped to 2000MB now.
[01:40] <genewitch> it's my 'primary' linux machine, too.
[01:40] <sarnold> hehe, I bet it reboots in a few seconds, too, thanks to caching in the host :)
[07:20] <KervyN> gosh peta.. http://motherboard.vice.com/read/peta-sues-for-copyright-on-behalf-of-selfie-taking-monkey :-/
[08:45] <KervyN> hi, some1 got an idea how to configure squid3 to cache by filename? I want to build a deb/rpm proxy and ignore the hostname
[12:03] <T3DDY> Can HDD failure cause Ubuntu server to crash at startup?
[12:07] <lordievader> Yes.
[12:13] <RoyK> T3DDY: a disk failure can do most annoying this, so yes. better boot on something live and run smartctl -a /dev/whateveritsname
[12:14] <T3DDY> Cool, thank you
[12:26] <lordievader> +1
[12:28] <Eldunar> hello. I intstalled ubuntu-server on vbox. It is working on windows host (Connection by putty). But on linux host it is not working. I can not connect to server via ssh. It says that Network is unreachable. I set the network adapters with same options. Can u help me?
[12:42] <kgirthofer> i'm installing libreoffice on a cli server, it's failing out on the install of gnome-integration. I can skip that yes, I shouldn't need anything from gnome
[12:42] <jrwren> KervyN: I think apt-cacher-ng does that. it keeps a list of mirrors and considers paths to them to be the same.
[12:47] <Eldunar> hello. I intstalled ubuntu-server on vbox. It is working on windows host (Connection by putty). But on linux host it is not working. I can not connect to server via ssh. It says that Network is unreachable. I set the network adapters with same options. Can u help me?
[12:48] <Eldunar> i have eth0 and eth1 visible. eth1 ipv4 is 192.168.56.101
[12:49] <Eldunar> and i can not log in there. i allowed ssh in ufw and i am out of ideas
[12:49] <bananapie> If I mount to a folder that has files in it, can I access the files or are they unreachable until I umount the folder?
[12:51] <bananapie> nevermind, I found the answer
[12:53] <quantic> kgirthofer: libreoffice doesn't care if its going on a headless box, it's a GUI application and has the associated dependencies.
[12:53] <kgirthofer> the install script removes a few of the gui dependencies, I think I can remove them
[12:54] <kgirthofer> I can't use the install script
[13:33] <ParsectiX> Guys I'm using LDAP to have my user Database. How can I sync the system users also ?
[13:33] <ParsectiX> My concern it's for the root/administrator user to have a fail-save mechanism to login on the server.
[13:35] <jrwren> ParsectiX: my experience in this area is very dated, but afaik, there are no good solutions for this.
[13:38] <ParsectiX> jrwren: thanks for the answer
[13:40] <ParsectiX> I just want somehow to have my administrator password locally on each server and also I can change/sync it centrally so every machine can get the change.
[13:52] <patdk-wk> no good solution to this?
[13:53] <patdk-wk> I wouldn't recommend doing that at all
[13:53] <patdk-wk> just sync your ssh keyfile
[14:15] <jamespage> coreycb, ok to work through rc1?
[14:16] <coreycb> jamespage, yep I can start today
[14:52] <Guest92591> how can i now what requires systes restart when i get msg on login "1 package can be updated.
[14:52] <Guest92591> 0 updates are security updates.
[14:52] <Guest92591> *** System restart required ***
[14:52] <Guest92591> sorry, should only put that system restart required
[14:53] <Guest92591> what requires my system to be restarted ? where can i find out it ?
[14:53] <Guest92591> 0 updates are security updates.
[14:53] <Guest92591> *** System restart required ***
[14:53] <Guest92591> damn
[14:53] <Guest92591> sry, accident paste
[14:54] <lordievader> Usually kernel updates.
[14:54] <Guest92591> damn laptops, should disable the touchpad
[14:54] <Guest92591> lordievader: but if it isnt kernel ?
[14:54] <Guest92591> im gonna check ubuntu security msgs
[14:54] <lordievader> There are a couple of other things that require reboots. Libc for example.
[14:55] <Guest92591> but is it "required" if just normal use and nothing special than ssh running on server ?
[14:56] <ogra_> udev too ... upstart/systemd  would ask for a reboot as well i think
[14:56] <lordievader> Meh, required is a big word. Required to reboot if you want to run the new versions of the software, but if you don't want to reboot nothing is going to stop you.
[14:56] <Guest92591> i understand that if kernel update and for example remote root exploit in kernel but just a little update that doestn do anything special should not be a cause to boot a server
[14:56] <Tazmania> I am running a PPTPd server on a Ubuntu 12.04.5 LTS blade server to serve more than 1000 pptp clients.  As the number of clients grow, the ubuntu machine keeps crashing.  Any idea?
[14:57] <patdk-wk> why remote exploit in kernel?
[14:57] <patdk-wk> local exploit is horrible
[14:57] <patdk-wk> if you run any kind of remote services, such as a webserver
[14:57] <Guest92591> i run apache and ssh
[14:57] <Tazmania> I have also set up a watchdog timer but it doesn't seem to help.  When the server crashes, only a hard reboot will do.
[14:57] <Guest92591> apache2 with php5 and ssh
[14:57] <ogra_> lordievader, well, indeed, but i think all of them switch that notification on
[14:58] <ogra_> weather you listen to it is indeed up to you :)
[14:58] <patdk-wk> Guest92591, so any exploit in the kernel, local, remote, or otherwise, your vaunerable to
[14:58] <patdk-wk> unless you can guarrentee there is no exploit paths in your apache/php programs at all
[14:58] <patdk-wk> and I have never known that to ever be the case
[14:59] <Guest92591> patdk-wk: there is nothing that would be for me in ubuntu security notices for ubuntu-server 14.04 LTS and my software-config
[15:00] <patdk-wk> you only run php files from ubuntu? without modifications?
[15:00] <patdk-wk> you have never installed a php file outside of apt-get
[15:00] <patdk-wk> you have never been vaunerable to a 0day vaunerability
[15:14] <Tazmania> Is there a limit on the number of pptp clients that I can accept?
[15:14] <Tazmania> on a ubuntu server
[15:14] <cwillu_at_work> Tazmania, assuming nothing shows up in the logs before it crashes, I'd set up a netconsole to another machine, as the final gasps probably aren't being saved
[15:14] <cwillu_at_work> (if things _do_ show up in the logs, you should pastebin your logs :p)
[15:15] <teward> Tazmania: I think the max clients is limited by either a config option or your system's memory being consumed
[15:15] <teward> a 'crash' is also not very useful, because it could mean it segfaulted, or your server rna out of memory, etc.
[15:15] <neurotus> patdk-wk: but there's nothing in ubuntu security that would cause me a problem after last kernel reboot and apt-get upgrade
[15:15] <cwillu_at_work> (neither of which should cause a hard lockup)
[15:15] <teward> cwillu_at_work: except if all the swap is also consumed and something's not clearing it out
[15:15] <neurotus> patdk-wk: update and kernel change and reboot
[15:16] <cwillu_at_work> teward, in which case the oom killer gets involved, and the oom killer definitely will scream into the logs
[15:16] <teward> mhm
[15:16] <cwillu_at_work> (and if you've disabled it, well, stop hitting yourself :p)
[15:16] <neurotus> patdk-wk: no security notices for apache or php
[15:16] <teward> cwillu_at_work: oom-killer once hard-froze a Hardy system when it started killing things, so ehh
[15:16] <cwillu_at_work> [citation needed]; lots of things get confused for "hard froze"
[15:17] <Tazmania> what is oom-killer?
[15:17] <cwillu_at_work> Tazmania, probably not relevant, unless you have a log file that says otherwise :p
[15:17] <lordievader> Out of memory killer.
[15:17] <Tazmania> ok
[15:17] <Tazmania> thanks
[15:17] <cwillu_at_work> (have you looked at /var/log/kern.log after a crash?)
[15:18] <lordievader> To prevent OOM you usually have a bit of swap.
[15:18] <cwillu_at_work> erm
[15:18] <patdk-wk> neurotus, you seem to be confused
[15:18] <cwillu_at_work> you usually have a bit of swap so that you don't have to keep idle memory in physical ram
[15:18] <patdk-wk> what does a security notice have to do with apache or php?
[15:19] <Tazmania> MemTotal is 16GB and SwapTotal is also 16GB
[15:19] <patdk-wk> they can both be security free, and working as intented, and still allow people to run whatever they wish
[15:19] <cwillu_at_work> Tazmania, as I said, probably not relevant unless you've seen something in a log that suggests this is the problem
[15:19] <patdk-wk> I mean, you told it to run a php file
[15:19] <patdk-wk> if that php file allows you to, well, exploit the kernel
[15:19] <patdk-wk> well, your rooted
[15:19] <Tazmania> I am just checking the server detail and will look into the log
[15:19] <patdk-wk> and if not, your just now part of a botnet
[15:20] <neurotus> patdk-wk: but no kernel change after that or anything else im running
[15:20] <neurotus> patdk-wk: so im confused why reboot required
[15:20] <neurotus> patdk-wk: what log should i read ?
[15:21] <neurotus> patdk-wk: or install some security logging app
[15:25] <Tazmania> I get a lot of input/output errors from PTY failed
[15:25] <neurotus> patdk-wk: i read /var/log/apt/history.log and theres nothing security related after last reboot
[15:26] <neurotus> patdk-wk: i have only installed rtorrent after last boot
[15:26] <neurotus> so it should not require reboot
[15:33] <AvatarA> if you do an uptime -s and then pastebin that history.log I think you may find out that is not true
[15:35] <neurotus> AvatarA: ive done apt-get autoremove which removed old kernel from bootlist, should that be the cause ?
[15:35] <neurotus> AvatarA: a cloud-server im running
[15:36] <neurotus> AvatarA: kvm virtualization
[17:05] <hallyn> smb: arges: thanks guys.
[17:05] <smb> hallyn, yw
[18:03] <arcsky> hi guys im trying to connect to my wireless at home. i have some issues. it works with windows. what can i do?
[18:37] <krsna> arcsky: need more details..

[18:59] <arcsky> krsna: yes
[21:01] <orfeo> Hello folks!
[21:03] <orfeo> Could someone help me figure how to unblock a virtual server runing ubuntu-server please?
[21:03] <Serus> hi
[21:04] <orfeo> hi
[21:04] <Serus> my friend has recently upgraded his server to ubuntu trusty
[21:04] <patdk-wk> well, what is a virtual server
[21:04] <Serus> but now he's getting errors when trying to upgrade
[21:04] <patdk-wk> and how exactly did you block it
[21:05] <tonyyarusso> orfeo: What do you mean by "unblock"?
[21:05] <Serus> http://pastebin.com/Mk8jq8g3 these are the errors I'm getting
[21:06] <Serus> how can I resolve this? I'm pretty sure insserv is conflicting with upstart
[21:07] <orfeo> well, I did install a bunch of applications on it and now when I try to stop it running to reinstall it it won't allow me. I figure that it is because there is a process running which is somehow blocking the machine.
[21:08] <tonyyarusso> "when I try to stop it" means what, and "it won't allow me" means what?
[21:09] <orfeo> For example, when I try to shutdown the server via control panel I receive a message saying "An Error Occured! A process has already been instantiated for this virtual server. Please wait for the process to finish."
[21:09] <tonyyarusso> What control panel?
[21:09] <orfeo> the VPS control panel
[21:10] <orfeo> it is a virtual server. Not local.
[21:10] <tonyyarusso> What happens why you try to shut it down from within the machine itself?
[21:10] <orfeo> do you mean via ssh?
[21:11] <orfeo> what command should I use for that?
[21:11] <Serus> Could anybody help me try to resolve my errors with insserv?
[21:11] <tonyyarusso> SSH or virtual console - either way.
[21:11] <tonyyarusso> shutdown....
[21:11] <orfeo> Hold on, let me try it.
[21:13] <orfeo> tonyyarusso: shutdown: time expected
[21:13] <tonyyarusso> Yup
[21:13] <tonyyarusso> Look at the man page for the syntax.
[21:15] <Serus> http://pastebin.com/Mk8jq8g3 can anybody please help me with this?
[21:19] <orfeo> the worst happened. I did shutdown now, lot access and the VPS control panel still blocked saying the server is runnig.
[21:19] <orfeo> how weird is that?
[21:20] <tonyyarusso> What arguments did you use?
[21:20] <orfeo> shutdown now
[21:21] <tonyyarusso> So you didn't halt it.
[21:21] <orfeo> is it a problem?
[21:23] <tonyyarusso> Well, that's why your server is still running.
[21:23] <orfeo> Should I use a shutdown -q now ?
[21:26] <tonyyarusso> -h is what you wanted
[21:26] <tonyyarusso> I don't think there is a -q...
[21:27]  * tarpman generally invokes poweroff(8) rather than try to remember the correct shutdown(8) incantation...
[21:28] <orfeo> I thought I saw it. Well, never mind, now its too late. But thank you anyway.
[21:29] <genii> I use shutdown -h now to halt, shutdown -r now to reboot
[21:30] <orfeo> genii: cool, good to know. For the next time maybe.
[21:31] <sarnold> Serus: do you need ppp stuff? I think first thing I'd try is apt-get purge ppp pppconfig pptpd ; if you need mdadm for raid on the system to work, leave that alone for now...
[22:06] <Serus> sarnold: some guys in #ubuntu helped me, thanks anyway!
[22:06] <sarnold> Serus: oh cool, what'd they do?
[22:09] <TJ-> sarnold: not a lot! Turns out Serus' server release upgrade crashes part way through and it was hard-rebooted
[22:10] <sarnold> TJ-: ah, thanks :D
[22:11] <patdk-lap> tarpman, I do that too
[22:11] <patdk-lap> but I learned on some systems, the poweroff command means just that
[22:11] <TJ-> But I dug into the issue with insserv; it *seems* there's a bug in the LSB headers for the /etc/init.d/mdadm script declaring it requires mdadm-raid, but no such service file exists
[22:12] <patdk-lap> direct poweroff, WITHOUT safely unmounting or syncing the filesystems
[22:12] <tarpman> patdk-lap: poweroff without shutting down first, you mean?  which systems do that?
[22:12] <patdk-lap> solaris
[22:12] <tarpman> ah k
[22:12]  * tarpman mental note
[22:13] <patdk-lap> gone oldschool on those, init 0
[22:13] <sarnold> tarpman: beware of the 'reboot' command there too
[22:13] <patdk-lap> na, reboot is sane
[22:13] <sarnold> oh? was it sunos that just insta-rebooted then?
[22:13] <patdk-lap> ya, same deal, but htat is safe
[22:13] <sarnold> .. if you wanted sync and umount, you would typed those too :)
[22:13] <patdk-lap> no, that is different
[22:14] <patdk-lap> reboot would do a normal safe reboot
[22:14] <patdk-lap> but it would not do a bios reboot by default, but just a kernel reload, if all the drivers supported it
[22:14] <patdk-lap> otherwise you needed to do a reboot -p, to force a full bios reboot
