| uxfi | Hwo do I change the username of Ubuntu server? | 02:47 |
|---|---|---|
| uxfi | To change username (it is probably best to do this without being logged in): | 02:47 |
| uxfi | Hwo do I do that if I am logged in? | 02:47 |
| sarnold | changing usernames is hard | 02:48 |
| sarnold | far easier is to create a new user with the name, group memberships, etc., that you want | 02:48 |
| uxfi | I get this message | 02:58 |
| uxfi | usermod: user mitraj is currently used by process 1861 | 02:58 |
| uxfi | what do I do? | 03:00 |
| bigjazzsound | uxfi: the user will have to not have any processes running to change the name | 03:00 |
| uxfi | ah | 03:01 |
| uxfi | bigjazzsound how do I do that? | 03:01 |
| bigjazzsound | uxfi: you can do something like `ps aux | grep username`. Check the processes that are running under that user. The do `kill processid` to kill them off. | 03:03 |
| uxfi | ok | 03:03 |
| bigjazzsound | uxfi: some of the processes might be inadvisable to kill, which is why sarnold suggested to make a new user instead with the same permissions, groups, etc | 03:03 |
| uxfi | right | 03:03 |
| uxfi | like SSH | 03:03 |
| bigjazzsound | Exactly | 03:04 |
| uxfi | so I should make a new user i guess? | 03:04 |
| uxfi | bigjazzsound well actaully if I can change the name without needing to make a new user is htat possible? | 03:04 |
| sarnold | the thing is it's more than just changing /etc/shadow /etc/passwd and their home directory -- you may need to modify mail spool names, crontab names, maybe atd names, etc | 03:05 |
| bigjazzsound | uxfi: then you run into the issue with processes running under that user, no? | 03:05 |
| sarnold | if you've set up any per-user access controls on databases then those too | 03:06 |
| sarnold | etc | 03:06 |
| uxfi | bigjazzsound which isnt many | 03:06 |
| uxfi | jsut ZNC | 03:06 |
| uxfi | and systemd | 03:06 |
| uxfi | bigjazzsound ill make a new user | 03:08 |
| bigjazzsound | Sorry I could not be of much help here | 03:09 |
| uxfi | its ok bigjazzsound | 03:10 |
| uxfi | i dont want ot lsoe ZNC settings but I can rengegerate them | 03:11 |
| sarnold | you can of course move the data by hand.. | 03:11 |
| bigjazzsound | creating a new user and moving the stuff you need might not be a huge deal | 03:12 |
| bigjazzsound | ^^ | 03:12 |
| uxfi | ah | 03:13 |
| uxfi | I forget where it is stored hmm | 03:13 |
| keithzg | Well, I must admit to being very confused. Migrated a very old conf to a new server, and I have postfix-pcre installed, but I'm still getting "warning: pcre:/etc/postfix/header_checks is unavailable. unsupported dictionary type: pcre" | 03:21 |
| sarnold | keithzg: check output of dpkg -l '*pcre*' and make usre it makes sense | 03:22 |
| keithzg | sarnold: only installed packages look to be libpcre3 and postfix-pcre | 03:23 |
| uxfi | ok nwo i gave the temeproary account sudo access can I delete the origianl one? | 03:25 |
| sarnold | keithzg: then i'm out of ideas.. | 03:25 |
| uxfi | ok now i gave the temeproary account sudo access can I delete the origianl one??? | 03:25 |
| sarnold | uxfi: (a) test the new account first (b) make sure you copied over -everything- from the original that you want to keep. if youv'e done that then go ahead. | 03:25 |
| uxfi | I did sarnold I think | 03:26 |
| uxfi | I tested sudo su | 03:26 |
| uxfi | I tested sudo apt-get update | 03:26 |
| uxfi | seems to work | 03:26 |
| uxfi | I dont have anything in the user folder sarnold the only important thign I ahve is ZNC settings | 03:26 |
| uxfi | sarnold also myw ebsite stuff for some reason its not letting me access /var/www? is there a reason? | 03:26 |
| uxfi | and also will I lose mysql install? | 03:26 |
| sarnold | uxfi: what permissions did you set on /var/www? if you changed owner or set acls you may need to do that again | 03:29 |
| sarnold | uxfi: and probably not lose mysql but if your useraccount had privileges within the mysql database that other users didn't have you may need to redo that too | 03:29 |
| uxfi | I forget what permissions | 03:29 |
| uxfi | sarnold but I made a copy of my /var/www anwyays | 03:29 |
| uxfi | bash: cd: /var/www/: Permission denied | 03:30 |
| sarnold | check with something like find /var/www -ls | 03:30 |
| uxfi | hmmm | 03:30 |
| uxfi | bash: /var/www/: Is a directory | 03:31 |
| uxfi | sarnold | 03:31 |
| uxfi | got any ideas? | 03:31 |
| sarnold | uxfi: namei -l /var/www/htdocs | 03:31 |
| uxfi | ah | 03:32 |
| uxfi | mitraj owns that sarnold the root user | 03:32 |
| uxfi | the account im trying to delete | 03:32 |
| uxfi | sarnold https://i.imgur.com/QoHJ4ln.png | 03:33 |
| sarnold | uxfi: aha, then you'll want to chown /var/www and subdirs to the new user | 03:33 |
| uxfi | ah | 03:33 |
| uxfi | a1berto so log into the old account? | 03:34 |
| uxfi | oops | 03:34 |
| uxfi | sarnold chown what? chown 770 or? | 03:35 |
| sarnold | chown -R newmitraj /var/www | 03:35 |
| sarnold | time ot make dinner :) have fun uxfi | 03:36 |
| uxfi | ah | 03:36 |
| uxfi | what is newmitraj vaishali ? | 03:37 |
| uxfi | sarnold ? | 03:37 |
| keithzg | sarnold: honestly the header checks are the smallest part of my postfix conf so I've just disabled that for now, heh. Frankly a bit astonished that this config, which was set up on a *Trustix* server until today, is even working! :D | 03:39 |
| uxfi | am I doing this right? | 03:42 |
| uxfi | what od I do to take contro of my directory when I make a new account? | 03:42 |
| uxfi | ah nvm | 03:43 |
| uxfi | got it | 03:43 |
| uxfi | Question when I delete a account from Ubuntu (the original admin account) and make a new account will I still get the default ifnormation when I log in (Packages need to be updateD) ? | 03:44 |

| jamespage | mwhahaha: I've pushed 4.1.1 to updates, but I think that magnum problem might be related to the newer sqlalchemy | 07:46 |
| jamespage | this is a bit of a problem for projects which are not following the main release cadence for Openstack | 07:46 |
| blueking | dpkg: feil: dpkg-statusdatabase is locked by another process. / N: Fila «50unattended-upgrades.ucf-dist» in map «/etc/apt/apt.conf.d/» are ignored, because of not guilty file end. / E: Sub-process /usr/bin/dpkg returned an error code (2) | 07:46 |
| blueking | what I do ? | 07:46 |
| cpaelzer | blueking: it seems your message is shortened | 08:00 |
| blueking | it was in norwegian had to translate | 08:01 |
| cpaelzer | blueking: the message "not guilty file end" reads odd - but in general anything that is not .list in /etc/apt/apt.conf.d is ignored | 08:01 |
| cpaelzer | ah fine then blueking | 08:01 |
| cpaelzer | so the message tells you that this file is ignored - the ending "ucf-dist" suggests on which upgrade it was disabled | 08:02 |
| blueking | yes | 08:02 |
| cpaelzer | as upgrades usually invalidate old PPA/apt.conf setups they renae them | 08:02 |
| cpaelzer | The other message about dpdk DB being locked is usually another process installing/updating something at the same time | 08:03 |
| blueking | dpkg: fail/error: dpkg-statusdatabase is locked by another process | 08:03 |
| cpaelzer | so if you in a console wrestled with packages, but the auto-updater triggered that might occur (not sure if it has collision detection in unattaneded upgrades) | 08:03 |
| blueking | I did 14.04 -> 16.04 distro upgrade.. a few apt upgrades later, the last two I have had this dpkg error | 08:04 |
| cpaelzer | so your real issue is the locking then, just to close the ucd-dist here a reference if you want more on that https://askubuntu.com/questions/829370/n-ignoring-file-50unattended-upgrades-ucf-dist-in-directory-etc-apt-apt-con | 08:05 |
| cpaelzer | blueking: I think one can check and force to unlock - let me look if I find what I think I remember :-) | 08:05 |
| blueking | I'll look into that :) TY :) | 08:05 |
| cpaelzer | blueking: for the locked dpkg it could be an aborted upgrade (aborted harder than ususal to cause this) | 08:07 |
| cpaelzer | blueking: please follow this https://askubuntu.com/questions/219545/dpkg-error-dpkg-status-database-is-locked-by-another-process | 08:07 |
| cpaelzer | blueking: and let us know if it helps | 08:07 |
| blueking | hmm lock file empty ? | 08:09 |
| blueking | ok I deleted lock file and that part gone | 08:11 |
| blueking | about dpkg locked by another process | 08:11 |
| blueking | ok error gone deleted 50unattended-upgrades-ucf-dist | 08:13 |
| cpaelzer | blueking: did you check if there was a process still holding it? | 08:14 |
| blueking | yes was none process | 08:16 |
| blueking | checked with lsof | 08:16 |
| cpaelzer | ok good | 08:16 |
| blueking | lock file was empty | 08:16 |
| cpaelzer | blueking: now does a new update work now? | 08:16 |
| blueking | yes | 08:16 |
| cpaelzer | great | 08:16 |
| blueking | good to have zero errors :) | 08:16 |
| cpaelzer | "flott" | 08:16 |
| blueking | norwegian ? | 08:17 |
| cpaelzer | no trying to go intercultural with google translate, but I'd have got the meaning of "flott" in german as well :-) | 08:17 |
| blueking | ah I see :) | 08:20 |
| blueking | 'flott' not youth language :P | 08:20 |

| ahasenack | I have a systemd question, and it boils down to "how to disable a service from a package maintainer script (postinst)", considering that in debian/ubuntu by default if you install a service it will be started | 14:18 |
| ahasenack | and here is the current example: samba's samba.postinst: http://pastebin.ubuntu.com/24644329/ | 14:18 |
| ahasenack | the service in question is samba-ad-dc.service | 14:18 |
| ahasenack | it does a "ln -s /dev/null /etc/systemd/system/samba-ad-dc.service" | 14:19 |
| ahasenack | and via echo asks the user/admin to ignore an error that will show later on | 14:19 |
| ahasenack | is that the only way? | 14:19 |
| ahasenack | the error you get is just on screen, exit status is zero: http://pastebin.ubuntu.com/24644378/ | 14:21 |
| Ussat | So....anyone here have experiance setting up 802.1x port secrity on a wired network ? | 14:39 |
| teward | rbasak: you're welcome. I wanted to write it *somewhere* so I just stuck it two levels underneath the NGINX page. If we need to revise it, let me know, but if not we can use *that* as the release notes for Artful. | 14:41 |
| teward | for the nginx subsection. | 14:41 |
| teward | the full list of changes was *long* so I only grabbed a few of the pertinent points from the nginx blog post :P | 14:41 |
| jge | hey all, I have a network share mounted to an NFS mount point in Ubuntu but when I try to rsync files within that share I get permission denied | 15:17 |

| arunpyasi_ | Hi all | 15:20 |
| arunpyasi_ | Can an ethernet connection be disconnected due to file download ? | 15:20 |
| teward | arunpyasi_: if the router or a proxy sends a connection termination signal, possibly. | 15:45 |
| teward | why? | 15:45 |
| TafThorne | If the download uses all of the available capacity on any part of the end-to-end link a network device might have to drop it. | 15:46 |
| TafThorne | As in it has to get a quart into a pint pot and your Ethernet connection might be part of the spillage. | 15:47 |
| TafThorne | jge: You get a permssions result for some odd cases in network shares and exports. Do you have permission to write within the export at all on both ends of the link? | 15:49 |
| arunpyasi_ | Hmm OK thanks ! | 15:56 |

| paxatron4034 | Anyone here with corosync knowledge? I have questions on using postgresql with corosync/pacemaker. | 19:38 |
| paxatron4034 | \? | 19:40 |
| sarnold | paxatron4034: you may get better results with a 'concrete' question | 19:41 |
| mason | sarnold: Did you know that concrete was used as far back as ancient Rome? | 19:42 |
| mason | FWIW: https://en.wikipedia.org/wiki/Roman_concrete | 19:42 |
| sarnold | mason: crazy. I guess it makes sense that our accomplishments are built onthe knowledge and experience of previous generations but you just sort of assume that olden times were insanely primitive, right? | 19:43 |
| paxatron4034 | @sarnold well. I am running postgresql as a resource in corosync. and there is a monitor process that kicks off every few seconds to see if postgresql is alive (it runs a select now). My immediate conserning is that it is generating alot of logs in auth.log, and I am wondering of this is normal behavior https://pastebin.com/UnR3tBdi | 19:44 |
| sarnold | paxatron4034: eww, i'm surprised they don't re-use a single long-lived process | 19:45 |
| sarnold | paxatron4034: quite often 'large' deployments will shuttle logs to a centralized log server, reducing the impact of logging on disk IO on the individual servers | 19:45 |
| paxatron4034 | \r sarnold okay, but is this normal behavior for postgresql corosync resource? | 19:48 |
| sarnold | paxatron4034: probably | 19:49 |
| paxatron4034 | sarnold: thanks | 19:54 |
| sarnold | paxatron4034: itm ight be worth a report to the project to let them know the logspam is annoying :) maybe they'd be willing to re-do the test.. | 19:55 |
| sarnold | or maybe that's just the way their tests work out. | 19:55 |
| henk717 | Hello everyone, i updated the packages on my Ubunu Server 14.04 yesterday and now i am experiencing some of my cron.d jobs no longer running. Can someone help me diagnose this issue? | 20:10 |
| nacc | henk717: are you able to determine which packages were updated? | 20:34 |
| nacc | smoser: ping | 20:36 |
| mason | nacc, henk717: Does 14.04 have /var/log/apt/history.log ? | 20:36 |
| mason | That might help. | 20:36 |
| nacc | mason: yeah, i believe it should | 20:37 |
| mason | Ah, looks like it should be. | 20:37 |
| nacc | mason: if not the dpkg log would | 20:37 |
| henk717 | It was a huge list, the server was quite behind on updates | 20:37 |
| henk717 | Another server of mine runs on 16.04 with slightly newer packages and has no issues | 20:38 |
| henk717 | The cron jobs can run if i run them by hand | 20:38 |
| henk717 | They do not get automatically executed | 20:38 |
| nacc | henk717: do you have an example cron entry that fails? | 20:38 |
| nacc | henk717: also, do you get an e-mail about any errors | 20:39 |
| henk717 | Yes, i do it seems to be one entire file. No errors are present in the logs as far as i have seen. | 20:39 |
| nacc | henk717: well, it often won't be logged, but if there was an error, I believe root (or the configured user for cron mails) will receive one locally | 20:39 |
| nacc | henk717: but it soudns like, it's not failing, it's just not even running? | 20:39 |
| nacc | henk717: which file? | 20:40 |
| henk717 | It looks like it is not even running indeed, cron runs though and some other cron jobs did ran | 20:41 |
| henk717 | File is /etc/cron.d/overwatch which contents i am currently posting on pastebin for you to see | 20:41 |
| henk717 | https://pastebin.com/GUE1704S | 20:43 |
| nacc | um, i don't think you can have users in the crontab like that | 20:43 |
| henk717 | It always worked | 20:43 |
| henk717 | The same file runs perfectly on a 16.04 machine | 20:44 |
| nacc | only /etc/crontab (I believe) supports that format (per `man 5 crontab` | 20:44 |
| henk717 | It would be quite specific if the lower version handles this fine and the higher version handles it fine | 20:45 |
| smoser | nacc, here. | 20:45 |
| teward | nacc: the system /etc/crontab can have user definitions | 20:45 |
| teward | user level crontabs can't | 20:45 |
| teward | and user level crontabs are *usually* how you do things | 20:45 |
| nacc | smoser: hey, wanted to bounce something off you about the git tooling, if you have a minute for a HO? | 20:46 |
| nacc | teward: right, what i said -- but is /etc/cron.d/* a 'system' crontab? | 20:46 |
| henk717 | In my experience it has been | 20:46 |
| smoser | sure | 20:46 |
| teward | nacc: yes. | 20:46 |
| nacc | henk717: ah ok, it is considered the same, sorry | 20:47 |
| henk717 | nacc: No problem, i apprechiate you thinking along | 20:47 |
| henk717 | Fact remains its a proven cron setup prior to the update which runs on a newer cron version as well | 20:47 |
| teward | nacc: http://paste.ubuntu.com/24647476/ <- example, from mdadm's automatic crontab it installs | 20:47 |
| nacc | teward: yep, i'm seeing that now | 20:47 |
| henk717 | What makes the issue more difficult is that there is no error anywhere to be seen, and i can run any of the scripts manually without any failure | 20:50 |
| nacc | henk717: i'm not sure how to debug it. I would start with adding a new crontab at the same level, with a test cronjob and see if it triggers. Then start adding lines from the non-working to the test one and see when/if it breaks | 21:21 |
| henk717 | nacc: Currently planning to upgrade to 16.04 if there isn't to much risk involved | 21:25 |
| nacc | smoser: re: LP: #1569925, I think one of the two iscsi services is supposed to kill all sessions on shutdown | 21:26 |
| ubottu | Launchpad bug 1569925 in systemd (Ubuntu) "Shutdown hang on 16.04 with iscsi targets" [High,Confirmed] https://launchpad.net/bugs/1569925 | 21:26 |
| nacc | smoser: so if that's not happening, probably that's what needs debugging | 21:26 |
| keithzg | sarnold: Yeah, Trustix to Ubuntu 16.04; I'm even more impressed now with the Postfix folks than I already was! | 22:04 |
| sarnold | :D | 22:04 |
| henk717 | Got good news and i got bad news, the upgrade to 16.04 was succesfull. Bad news is cron is still doing the same thing. | 22:38 |
| nacc | henk717: seems highlgy likely , if there is an identically configured server somewhere else at the same rev, that something else is going on :) | 22:39 |
| henk717 | Got more good news | 22:40 |
| henk717 | 16.04's cron dumps errors | 22:40 |
| henk717 | The newer versions didn't like the fact the reboot line had no user specified | 22:40 |
| henk717 | Its all fixed now :D | 22:40 |
| nacc | henk717: probably that was required on 14.04 too | 22:40 |
| nacc | ? | 22:41 |
| henk717 | On the new cron, yes totally | 22:41 |
| henk717 | But it threw no error | 22:41 |
| henk717 | On the old cron the line likely just got ignored | 22:41 |
| nacc | right, i'm saying that there is probably an improvement to be made to the error handling, but that might be why they weren't running | 22:41 |
| nacc | the crontab failed to parse | 22:41 |
| henk717 | The improvement is already made apparently, its just not in the 14.04 version since its out of support | 22:49 |
| nacc | henk717: hrm? 14.04 is still supported | 22:53 |
| nacc | henk717: perhaps file a bug, or see if one already exist | 22:53 |
| keithzg | Hmm, trying to set up a UEFI-capable PXE boot largely via https://wiki.ubuntu.com/UEFI/PXE-netboot-install, but on the (very new and high end!) PC I'm trying it on I'm getting the Intel Boot Agent throwing a fit, complaining "PXE-E79: NBP is too big to fit in free base memory" before it can even load the Grub menu. | 23:45 |
| keithzg | Any easy way to chainload into Grub for that? | 23:46 |
