[00:46] I'm running Server 16.04, so I figured to ask here. [00:47] I have kswapd0 running at 100% (almost) CPJ [00:47] Dunno what I could do to fix this :P [00:52] i-: is there anything interesting in dmesg output? [00:53] i-: what does smartctl status look like on your drives? [00:59] smartctl apparently gets an 'invalid argument' [01:01] dmesg looks like normal === JanC_ is now known as JanC [07:01] i-: kswapd at 100% likely means you are staying below some watermarks [07:01] i-: depending on numa setup you have one or more kswap kernel threads but that aside [07:02] i-: usually I'd expect you now want to find where your memory is: [07:02] this is actually an EC2 instance, btw [07:02] good to know [07:02] i-: a) spent with tools like smem or even just /proc/memofino and /proc/slabinfo [07:03] i-: b) track a bit how much is going on in terms of discarding pages and vm effort on it [07:03] for b there might be more modern things, but I still like systat for that [07:05] http://www-05.ibm.com/de/events/linux-on-system-z/downloads/Tools-MK2-V7-Web.pdf pages 72/73 and 149 would be where I'd start [07:05] i-: feel free to post the syststat and smem data somewhere to try to jointly interpreting them :-) [07:07] i-: an output of /proc/meminfo /proc/slabinfo /proc/zoneinfo and /proc/pagetypeinfo along the other data can also help to shed some light === Kenrins is now known as kenrin [09:25] rbasak: I realized that it might be reasonable to spend at least a bit of time when doing a merge to check for outstanding bugs [09:25] rbasak: most of the time this is just 30 minutes of cleanup, but sometimes one can find something important and add it right when merging anyway [09:25] rbasak: as well as trying to push remaining delta to debian [09:26] rbasak: I was wondering if we should add the two (pushing delta to debian + reviewing open bugs) to https://wiki.ubuntu.com/UbuntuDevelopment/Merging/GitWorkflow between step 6/7 or if you consider that "too much" [10:09] hi, say i have rails installed and i want to configure a different apparmor profile for each rails app, is there a way to do that? [10:16] cpaelzer: I think that's a good idea. [10:18] rbasak: thanks I'll add a very short statement as soon as the wiki lets me in === _degorenko|afk is now known as degorenko [11:16] rbasak: fyi picking the exim4 merge - ok ? [11:17] that is the next on my list, but you touched last so I wanted to hear an ack [11:18] cpaelzer: sure, thanks. I'm reviewing your ntp merge right now. [11:18] mdeslaur: you also uploaded exim4 recently - is it ok for you too that I take the work on the merge? [11:19] cpaelzer: please take it, thanks [11:43] Hello. I have a problem with preseeding Ubuntu 16.04 server amd64. Patched boot command line seems to ignore preseed/early_command string. Am I missing something? [11:44] Same procedure works perfectly for e.g. 15.10 and earlier versions. [11:45] ktt9: I'm not aware of anything that should have changed with that. I suggest you provide exact steps to reproduce in a bug report. [11:48] Okay, understood. === iberezovskiy|off is now known as iberezovskiy === utlmming is now known as utlemming [13:38] I opted for home folder encryption on ubuntu server 16.04 during installation. Now I want to be able to login as a different user and access my files. How do I do that ? [13:44] b3h3m0th: You dont. Because your home folder is encrypted per user. [13:44] b3h3m0th: you need to login two users then. [13:45] I did not get that [13:45] well, you could still mount it AFAIK [13:45] yeah, that's what I want to do [13:46] the home of user A is decrypted when user A logs in. So login user A to get that home decrypted, and switch users, and login user B. [13:46] I want to do that without logging in to user A [13:47] technically speaking, I want to figure out the decryption passhrase and the decryption command for /home/A/ (given I know the unix password for user A) from user B's shell [13:47] b3h3m0th: https://help.ubuntu.com/community/EncryptedPrivateDirectory [13:48] it's using ecryptfs [13:48] b3h3m0th: There is no way to guess the passphrase for the encryption from the known user password. [13:48] There is entirely no relationship between them, technically. You MIGHT set the same passphrases, but thats not a requirement at all. [13:49] b3h3m0th: Instead of trying to crack, just ask user A. [13:54] https://help.ubuntu.com/community/EncryptedPrivateDirectory#Recovering_Your_Mount_Passphrase [13:54] I need help with a nearly catastrophic problem with Ubuntu Server (14.04) on a Intel FakeRAID [13:55] We replaced a failing hard drive by another, and looks that the rebuild process instead of copying the data of the good disk to the new disk, has doing opossite! Now I have a raid volumen that is empty ! [13:55] Zardoz84: No it is time to restore your backup. [13:55] b3h3m0th: see there how you can get the mount passphrase [13:56] But lucky, we had a separate raid 1 to store the data [13:56] that have a BTRFS filesystem. I boot from the Ubuntu server cdrom on rescue mode, to check the data volumen, and I can't mount the partition [13:57] So you dont have a backup? [13:57] fdisk says that there is a single partition of GPT type, and when I try to list the partitions using -t gpt, I get an error [13:58] bekks: Yes, but I'm trying to restore the data hard disks [13:58] Zardoz84: Can you please anwer my questions? [13:58] Zardoz84: Do you have a backup? [13:58] bekks: Yes, I have backups of the data but I'm trying to restore the data hard disks [13:59] Zardoz84: they were overwritten. Restore your backup. [13:59] I know that I would need to reisntall the OS, but I need to know why this happen, so the next time that we replace a hard disk, we not get a server down for a entire day [13:59] don't use fake raid [14:00] bekks: As I said, I know that the SO volumen is lost and I need to reinstall it. What I'm worried, is about the data volume that looks that is Ok, but I can mount the partition [14:00] Zardoz84: USe a hardware raid controller. [14:00] and I wouldn't use btrfs either [14:00] JanC: Sadly, I can't choose the hardware [14:00] Zardoz84: Do you have a BACKUP on SEPARATE drives? [14:00] We have a backup on a network drive, so YES [14:01] you can ignore intel fake raid and use linux software raid [14:01] Zardoz84: So reinstall that thing, forget about whatever is on those disks, and restore. your. backup. [14:02] :( My kingdom for a real RAID.... === unreal_ is now known as unreal [14:47] bekks: I'd use mdraid over hwraid any day [14:47] s/use/choose/ [14:48] bekks: no need of asking user A [14:48] I am user A [14:48] :) [14:48] I did not set the passphrase [14:48] it was set up during installation [14:48] of ubuntu server [14:48] Then you are logged in as user A :P [14:49] but there is a catch [14:49] my ultimate intention is to set up (home folder encryption) and (key based ssh) [14:50] so, if home folder encryption is there, the ssh keys in home folder cannot be verified [14:50] so I am using https://stephen.rees-carter.net/thought/encrypted-home-directories-ssh-key-authentication [14:50] in that, I can login using my keys of user A [14:51] but then I have to unlock using my password [14:51] You could have asked that about an hour earlier. [14:51] but I want my decryption passhrase to be different from my unix password [14:51] for security reasons [14:51] Your initial question was totally different from your ssh issue. [14:51] yeah, I did not want to be off topic [14:52] brb. logging on. dinner [14:55] why would an ssh question be offtopic and an ecryptfs question not? [14:58] I think he means offtopic to the problem at hand, he was attempting to solve [15:00] well, even more reason to describe the exact same problem instead of something unrelated? [15:22] back [15:23] so the command mentioned in https://stephen.rees-carter.net/thought/encrypted-home-directories-ssh-key-authentication is not present in ubuntu server 16.04 [15:23] Which command...? === Guest51132 is now known as med_ [15:24] ecryptfs-mount-private [15:25] I'm wondering how it is mounted by ubuntu when I login normally [15:27] Check wether the package ecryptfs-utils is installed. [15:28] what was the command ? [15:28] something with --policy [15:28] nm [15:29] yes it is [15:32] oh [15:32] that command did work [15:32] path issues [15:33] and the passphrase is my unix password [15:33] how insecure of ubuntu server it did not even ask me for passphrase while setup :( [15:36] You could always change that. [15:37] hmm [16:17] The Server meeting seems sparsely attended today [16:18] happens [16:18] some of us were delayed due to other things (read: workplace requirements) [16:18] probably [16:18] (that was me) [16:20] Hello all, I am looking for the best solution to allow usernames / passwords from an active directory server to be used to log in with SSH to ubuntu server. This is the only feature I am looking for, no mountings/printers/user info, etc. Can anyone recommend a good guide? [16:21] Pinkamena_D: Simple LDAP might work, but you could also check out Centrify. It has a free version, if you don't require zoning. [16:21] Pinkamena_D: Install the agent, join the domain, done. One of my largest clients uses it extensively, it's very good. [16:22] This is a commercial organization so I am not sure if that would work [16:22] Pinkamena_D: So is Centrify. [16:23] Meaning, I don't need to worry about licensing. [16:23] Pinkamena_D: It's free version isn't a trial or anything like that. It's ONLY AD authentication. The paid version has a lot more features, if you require them. [16:23] hmm, well I will look into it [16:24] Pinkamena_D: The free version has a 200-system limit in terms of licensing. [16:25] In case this idea does not end up going over well, do you have any info on the pure LDAP solution you mentioned before? [16:26] Pinkamena_D: https://help.ubuntu.com/community/ActiveDirectoryHowto - Which, incidentally, mentions Centrify. [16:27] Pinkamena_D: Oh, I didn't know this. Centrify is in the Ubuntu partner repo. [16:27] Pinkamena_D: So you'd only have to enable the repo and install the package. [16:28] nice [16:32] Pinkamena_D: Or, well, it was for precise. === netsinn is now known as jiggalator [17:08] hi [17:09] in need of some guidance for cloud [17:09] hi in need of some guidance for cloud [17:11] harsh410: you're in need of asking a support question then. :) [17:12] ok and is this the forum [17:12] ?? [17:12] This is an IRC channel. [17:13] and it is for helping right [17:13] if u cant better say no [17:13] let others do that [17:13] If you dont want help, better say it. [17:13] Or ask your actual support question. [17:13] ofcourse i need it [17:13] Then ask your question. [17:16] harsh410: A specific question is easier to answer than a generalized one [17:16] u should have said so right away ......I want to set up a local cloud based system for 30 users of my office .i want a file sharing server and most importantly office softwares . i have been able to perform file sharing on virtual m/c i want to perform services as a service [17:16] for office softwares like libre write [17:18] 0726 191122 < bekks> harsh410: you're in need of asking a support question then. :) [17:18] I did. It was my first comment. You preferred to chitchat instead. [17:19] help me . if u can please..i may not know the protocols of discussion but my intentions are clear [17:19] You want to setup a fileserver. [17:19] As a VM, as you told us. [17:20] yes [17:20] yes [17:20] So whats the issue with that? [17:20] i was able to set up a file server and perform file sharing.next thing i want is to provide office applications as service [17:20] to users [17:20] Install an Ubuntu VM, install the file server services you need/want, and there you ho. [17:21] s/ho/go/ [17:21] If you want to provide office applications to users, you would have to provide a desktop for each user. [17:21] can the services be shared to them [17:21] if they dont install the softwares [17:21] if thin clients are given to them? [17:22] !ltsp [17:22] LTSP is the Linux Terminal Server Project, which adds thin-client support to Linux servers. See chapter 3 of the !edubuntuhandbook, http://www.ltsp.org and/or http://en.wikipedia.org/wiki/Linux_Terminal_Server_Project [17:22] Thats "giving a desktop to the users". [17:23] okay sounds useful and how are softwares like libre installed and managed?
