[00:02] Never mind i found it. [00:11] good nite === ponyride1 is now known as ponyrider [00:26] hello, ubunters, anyone able to interpret an error message from the boot loader? [00:27] i'm losing my mind with the USB install, have absolutely no problem producing an LIVEUSB on 18 or 19 Ubuntu but whenever I try to add persistence I get a mounting error [00:32] [7.896251] couldn't get size :0X8000000000000e === akemhp_ is now known as akemLenovo [00:43] https://pastebin.com/FbZCPEP1 There is some package missing on the repository? [00:45] My virtual box is currently broken because of that. :/ [00:47] Ha ok i think it was needing an update first. === BrianG61UK_ is now known as BrianG61UK [00:56] akemLenovo: all sorted? [00:58] sarnold, Yep, thanks. [00:58] cool cool [00:59] aken: I'm running Ubuntu on my brand new Lenovo P52. Works beautifully :) [00:59] akem* [01:05] WaV, nice :) mine is an old one, but it's very well supported, especially i got all the drivers for the hardware, no pblm. [01:31] I am trying to delete prtitions nd create one partition readable in Windows... Disks gives me the options of FAT16 <32M, FAT16 0x06, W95 FAT32, W95 FAT32 LBA 0c1c, W95 FAT16 LBA 0x1e. All I want is to create a file format that a bluetooth speak with a USB input can use. === jmcgnh_ is now known as jmcgnh === jmcgnh is now known as jmcgnh_ [01:33] Ascavasaion: I think I'd try W95 FAT16 LBA 0x1e first === jmcgnh_ is now known as jmcgnh [01:34] Ascavasaion: (I've got no real reason for preferring this variant over 0c1c -- I just vaguely think '1e' feels a lot more familiar a number) [01:35] sarnold, Okay hehe Thank you. [01:35] Ascavasaion: yikes wait [01:35] Ascavasaion: I just now noticed the 'fat16' in that name. that's terrible advice [01:35] sorry [01:36] Ascavasaion: FAT32 LBA seems most likely to give good results to me, and I misread that last option quite badly [01:37] sarnold, HAHA No problems... It tells em there is a partition still on the device. So I think I am either missing something obvious, or the USB stick is dodgy. [01:37] Ascavasaion: well.., there's "fdisk" partition tables and "gpt" partition tables and it's entirely possible that if you've wiped one the other may still be there.. [01:43] sarnold, I just took that 32GB USB stick out, replaced it with another 32Gb USB stick and it works. I think it is a broekn USB stick. Thansk for the help, and I am relieved because I thought I was losing my mind hehe === ben_r_ is now known as ben_r [01:50] Ascavasaion: hah, it wouldn't be the first time I've heard of a busted usb stick :/ [01:51] Ascavasaion: nice you had another one handy to test with :) otherwise that could drive you insane.. === zbenjamin_ is now known as zbenjamin [01:58] does anyone know how to get strace to output the uid of the process that it attaches to? [02:01] NickZ: I can't recall seeing a way to force strace to do that; you can grab it from /proc/pid/status (orlikely the other files, too) [02:46] sarnold: the problem is that the process dies way too quickly === TheFatherMind- is now known as TheFatherMind [02:57] Is the MOTD service enabled or disabled on Ubuntu Desktop by default? [03:33] does anyone have a good read on ubuntu networking? [03:33] I keep asking about setting up my vpn to route all traffic through it, and the only answer I get is cryptic at best with no actual commands. [03:33] How does networking actually work in Ubuntu. What are the relevant states and commands? [03:34] How do I actually learn how this works. I search for "ubuntu networking" and I get videos that don't actually explain how it works. They're just tutorials trying to solve a problem that isn't mine at all. [03:38] um1b0zu: depends what you're trying to learn about it [03:39] I want to learn about ifconfig and these weird words like tun0 and wlan and all this fun stuff about routing [03:40] well that's not ubuntu specific [03:41] i'd suggest learning the basics of networking first, then moving to the linux stuff [03:41] is there some form of tutorial or video that explains it with linux examples? [03:42] like what is tun0 and wlan? [03:42] tunnel 0 and wireless local area network [03:42] so how does routing work with them? [03:42] I fell like I manage those... I'm not even sure what those are. services? [03:43] see, i think you need to get the foundations of networking first [03:45] yes. what is this magic? [03:45] please say I don't have to read tannenbaum [03:46] it's a good one === xrandr_laptop_ is now known as xrandr_laptop [04:10] hello. I'm trying to setup a daemontools service to keep openvpn alive. systemd doesn't want to start it anymore. [04:10] I don't know how to set the environment variables in the bash script so it can find the files in /etc/openvpn [04:16] on3pk: come instructions https://wiki.archlinux.org/index.php/OpenVPN#systemd_service_configuration [04:18] ponyrider, I think an updated systemd binary is messing with my vps config. So I was actually just trying to launch it an alternate way [05:17] sometimes, any link I click on ubuntu, causes the currently running browser to crash [05:17] really frustrating because I keep losing work. [05:32] anyone running 19.10 atm? how's gnome 3.34 doing for you [05:32] are the performance improvements all they're cracked up to be? [05:33] I think you can ask that in #ubuntu+1. [05:34] thanks will do [06:00] Strange issue with Thunar on 18.04 - USB Flash devices mounted via udisks and gvfs show ownership or root:root in the GUI and therefore cannot be changed by the user they are mounted for *but* in shell the user has full control and ownership of the mountpoint, and the mount entry, both show the user as owner! [06:01] s/ownership or/ownership of/ [06:07] TJ-: try dbus-launch thunar === lotus|i5 is now known as lotuspsychje [06:30] ponyrider: thanks, I'll try that when I get back on that system. [06:35] I switch users and machines a lot and find the new info that login shows by default in 18.4 server to be annoying, not because of the info, but the delay that it imposes. Is there a QUICK and easy way that I can disable and re-enable this in a CLEAN manner. 16.4 was so much quicker [06:36] jpmh: you could maybe remove the internet aspects of it [06:37] jpmh: i think the stuff is here /etc/update-motd.d [06:37] EriC^^: yes, and that does work, but remember, I want a "quick and easy and clean: way. I guess I could have a script that makes and reverst the change. Was hoping for tomethinf cleaner [06:38] EriC^^: you are correct - in terms of where - and that does make the difference I want. It just stinks to do that [06:38] chmod -x /etc/update-motd.d/* ? [06:39] EriC^^: I like that idea, let me test that out - that woud be a BRILLIANT and quick and EASY and relatively CLEAN method [06:40] Hey, anyone knows if there is a way to know first/last block of a file on a hardrive, in order to scan for badblocks just theses sectors? [06:40] akemhp_: sudo parted /dev/sdX unit s print [06:41] what wine version do you have on ubuntu as latest? [06:41] akemhp_: you can get the blocks from sectors/block up in the drives description, 512 or 4096 [06:43] akemhp_: actually nevermind, i think you just need the sector number which is the block, i think [06:43] !info wine | kreyren [06:43] kreyren: Package wine does not exist in bionic [06:43] o.o [06:43] !info wine-staging [06:43] Package wine-staging does not exist in bionic [06:44] EriC^^, I think i can't know the blocks in relation to a specific file with parted. [06:44] akemhp_: what do you mean by specific file? file within the filesystem? [06:45] EriC^^, Yes. [06:45] yeah [06:45] EriC^^, I have one file that report an IO error in a software, so i wanted to scan only sectors used by this file. === freedom_ is now known as freedom [06:46] Cause scanning the entire disk is like more than 150 hours :/ [06:48] akemhp_: try sudo debugfs -R "stat /home/to/file" /dev/sdxY [06:51] akemhp_: or sudo hdparm --fibmap /path/to/file [06:53] EriC^^, Yeah i think i got it with begin_LBA and end_LBA in the second command. [06:53] Thanks EriC^^. [06:56] akemhp_: no problem [07:02] LUKS+LVM+BTRFS or LUKS+BTRFS? [07:05] BTRFS on top of LVM seems silly. BTRFS itself can handle multiple volumes and dynamic sizing, no? [07:07] That's why I ask, I did read a post where they do it with lvm... [07:23] The reason for using LVM inside uf LUKS seems to be swap. I also asked in ##security and this was there point on that question. [07:24] Tuor: recent Ubuntu's favour a swap file rather than dedicated partition [07:24] This is a problem inside of BTRFS [07:24] AFAIK [07:24] EriC^^: You idea was GREAT! Still a little slower than the old system because it tries a bunch of stuff - but MUCH better thanks so much. Now thinking of haveing two directories, one with all the files and the other without them and switching them in an out - sort of based on your idea [07:26] Or not... [07:27] Have to check again. [07:28] I'll ask in #btrfs === _dbugger is now known as dbugger [07:32] jpmh: you could just stop the update-motd task itself on login [07:33] TJ-: how would I do that? [07:34] jpmh: in /etc/pam.d/login (and /etc/pam.d/sshd) there is "session optional pam_motd.so motd=/run/motd.dynamic" [07:34] TJ-: heading to look at that now - ty [07:35] jpmh: great, good to hear! [07:36] TJ-: that section of the file says it is for the keyring [07:36] TJ-: oops - never mind - there are multiple sections - sorry [07:37] jpmh: if you add "noupdate" to those it'll stop the dynamic update, see "man pam_motd" [07:37] TJ-: TY so much - this is EXACTLY what I need [07:37] swap file inside of btrfs is only working since kernel 5.0 (before there is risk of data loss) [07:37] jpmh: that way the motd-news.service/timer will still work and update the file but it won't be updated on logins [07:39] !cookie | TJ- [07:39] TJ-: Wow! You're such a great helper, you deserve a cookie! [07:40] oooo breakfast time :) [07:40] TJ-: the "noupdate" on the second line was all that is reqred since the first already has it [07:41] jpmh: right; the 2nd is reading the default static /etc/motd whereas the first reads the dynamic copy [07:42] this is WHY I LOVE Ubuntu - the supprt here is SO GREAT! Thank you EriC^^ and TJ- [07:58] in apt list --installed what does [installed, automatic] and [installed, auto-removable] mean [07:58] and what man page do I open to read about that [08:02] installed means you installed that package, auto means it was pulled in by a dependency and could be removed if the dependent package is removed or no longer requires it. [08:04] what's auto-removable? [08:06] illuminated_: if you pastebin whats happening to your apt, volunteers can take a look whats happening to your system [08:07] https://paste.fedoraproject.org/paste/ODklHlUY6dL68TPwk0bRgw [08:07] auto-removable means that you did not explicitly install that package, it was pulled in as a dependency of another package or a build dependency and isn't needed anymore. [08:09] I installed wine64 via apt, then later did an apt update and apt list --upgradable. showed that wine, among other things was upgradable. So, I did an apt full-upgrade. Then it broke my wine. [08:09] so I'm trying to figure out what happened [08:09] illuminated_: that paste url lags on my end, perhaps try paste ubuntu, or pastebin? [08:11] https://paste.ubuntu.com/p/g6tRYWyhz2/ [08:12] !uptodate | illuminated_ what happens wehn you: [08:12] illuminated_ what happens wehn you:: To ensure you have all the latest known patches and security updates for your ubuntu installation, please update with the following command: `sudo apt update && sudo apt upgrade`. See also !upgrades and !security; you may also need to run `apt full-upgrade`. [08:13] I added the winehq repo first before I did apt-update and apt full-upgrade [08:13] how do I check what repo the package is from? [08:13] is that possible? [08:13] illuminated_: we dont support external ppa's and advice to use packages from the official ubuntu repos [08:14] well, I didn't "mean" to use it when I updated [08:14] nonetheless, is there a way to check what repo a package installed from? [08:15] illuminated_: apt policy packagename [08:16] illuminated_: we often see apt dependency & package conflicts by adding external ppa's here, reccomended to !ppapurge the external ppa's to revert to ubuntu vanilla sources [08:16] !ppapurge [08:16] To disable a PPA from your sources and revert your packages back to default Ubuntu packages, install ppa-purge and use the command: « sudo ppa-purge ppa:/ » – For more information, see http://www.webupd8.org/2009/12/remove-ppa-repositories-via-command.html [08:21] TJ-: one more question - with that noupdate in pace will my messages EVER get updated? [08:22] lotuspsychje: sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main' <-- that is the command I issued to add the repo. It wasn't a ppa. At least I don't see a ppa name for ppa-purge to do its thing. It's listed in /etc/sources.list. Could I just del the line from there? [08:30] i need a ascii's hex editor which will allow me to visualize the ascii code as i m editing the normal text... [08:33] I have some virtual/hosted servers that run beutifully however there is a horrible pause on booting when it tries to start urandom, I assume bacuse of no entropy, so I installed haveged thinking that it would help, it does not - any other ideas? === mouseleums is now known as mouses [08:43] illuminated_: perhaps in sources.list.d? === mouses is now known as mouseleums [08:49] I am doing this in system service but no logs.txt is being created. ExecStart=/usr/bin/node /home/ubuntu/api/dist/app.js |tee /home/ubuntu/api/logs.txt [08:51] There's no shell to parse that | [08:51] so most likely it's just passing '|tee' '...logs.txt' as two arguments to your app [08:57] jpmh: sorry, was away. Yes, as I said, the motd-news.service triggered by the motd-news.timer will do the updates [08:58] TJ-: TY so much - this is the PERFECT solution then - not clear to me why this is not the default [08:59] Intelo: you need to set the StandardOutput= in the unit, but the default should be to capture stdout to journal anyhow [08:59] TJ-, how exactly? [08:59] TJ-, won't this work? ExecStart=/bin/sh -c '/usr/bin/node /home/ubuntu/api/dist/app.js |tee /home/ubuntu/api/logs.txt' [08:59] Intelo: see "man systemd.exec" and the sections on StandardOutput= and StandardError= [09:10] I really wonder why Ubuntu has POSIX as default locale in docker containers, when it does not have that in normal installations.. [09:29] probably because any locale they pick will be wrong for someone [09:31] and it's wasted space to have unneeded locales installed [09:43] I All, i have an Ubuntu 16.04 32bit and i try to run UnrealTournament 99, i have installed all, and it's time to activate the script which run the server (and check if it fail to reboot it). I'm getting in the logs the following error: "Couldn't run ucc (ucc-bin). Is UT_DATA_PATH set?", i tried following the fix that is shown here "https://wiki.unrealadmin.org/Server_Install_linux", But still [09:43] without help, can anyone help me a bit ? [09:54] Hi, dudes! [10:04] join ##security [10:20] Nighthawk`: maybe in #unrealengine or ##linux you could get help with this, this software is not part of ubuntu and thus not supported here. [10:22] Ok, you are right :) [10:38] hello, anyone here with mdadm knowledge/experiences? [10:38] !ask | chris768443 [10:38] chris768443: Please don't ask to ask a question, simply ask the question (all on ONE line and in the channel, so that others can read and follow it easily). If anyone knows the answer they will most likely reply. :-) See also !patience [10:40] also: hello there. [10:40] I have a md0 raid6 in an "unclear" state. [10:40] dmesg says: "md/raid:md0: cannot start dirty degraded array." [10:40] mdadm --detail /dev/md0 [10:40] State : active, degraded, Not Started [10:41] pastebinit /proc/mdstat [10:42] https://paste.ubuntu.com/p/2Bxfmj7VW8/ [10:43] mdadm --detail /dev/md0 [10:43] https://paste.ubuntu.com/p/CMfBv4mpmv/ [10:44] which ubuntu version is this? have you identified the root / original event which caused the raid to become dirty / degraded, yet? [10:46] tl;dr: /dev/sdd failed last morning. After 15min. the rebuild to /dev/sdg "hangs" at ~130kbs about 8 hours. No reaction for "ls" or something else on the mountpoint. No unmounting, hanging write_job on the hanging mount-point (a btrgs snapshot). [10:47] After killing the snapshot process (and d-stated the process) and cant umount or anything else with the device, i restarted the hole server with uncommenting the automounts in fstab [10:48] now i am in this situation. im not really sure about the state. Is it active (like --detail says) or not (like /proc/mdstat says). [10:48] a --run says nothing, not even with --verbose [10:49] mount says: mount: wrong fs type, bad option, bad superblock on /dev/md0 [10:50] dmesg says: md/raid:md0: failed to run raid set. [10:50] (after the restart) [10:51] oh and, dmesg says before the "fail": md/raid:md0: cannot start dirty degraded array. [10:51] mdadm --assemble --scan -v: mdadm: Found some drive for an array that is already active: /dev/md0 [10:55] hmm right, i see how mdadm --detail says md0 is "active, degraded, not started" and mdstat says md5 is "inactive". this doesn't seem to add up [10:55] chris768443: i don't want to provide bad recommendation here, haven't been in this very situation, yet. [10:57] personally, if i could not get help in the manuals or on irc, i'd run review smart data on all drives, run a short self test on all drives and review smart data aagain, stop the array, then assemble it again, then start it. [10:59] chris768443: you didn't say which ubuntu version this is. also, which kernel version would be of interest. [11:00] this is a debian server, Debian 4.19.37. I know its not ubuntu, i am using ubuntu on my home servers. at this point i try to help a friend. [11:06] there's #debian here, just ask there then? [11:07] i have almost no experience with this kernel [11:09] tomreyn thanks for the advice, have a nice day :) [11:10] chris768443: have a nice days, too (and please only ask questions about ubuntu here int he future) [11:13] Hey folks [11:20] BluesKaj, hello === The_Milkman1 is now known as The_Milkman [11:50] I have a question about what package contains a certain lib... where can I ask?

[12:41] ramsub07: add -x if you want to limit it to the same file system [12:41] tomreyn: how do I make that more verbose? For example, it only gives me the total size of a directory. However, i would like to see the sizes of all the files and directories present(total inside the subdirectories) [12:42] (something like a hybrid between ls -lh and du -sh) [12:42] ramsub07: du -sh directory/* [12:42] ducasse: thanks! [12:44] ramsub07: du_recursive https://termbin.com/esma [12:44] ramsub07: also check out ncdu [12:45] the script i posted is a bit buggy though [12:49] tomreyn: thanks, serves my purpose! [12:53] does ufw block ephemeral ports? [12:54] bumblefuzz: not by default [12:54] which ports does it block by default? [12:54] bumblefuzz: that depends on how you have configured ufw [12:54] by default [12:55] by default, none [12:55] bumblefuzz: by default ufw isn't enabled in Ubuntu, you have to to turn things on [12:55] so, once it's enabled... [12:55] which ports does it block by default [12:56] bumblefuzz: In it's original configuration it is in a permissive state. It allows data that originated on the machine to leave, unrestricted and come back. Data comming from another computer on the network or internet is blocked [12:57] sudo status ufw verbose indicates: Default: deny (incoming), allow (outgoing), disabled (routed) [13:00] bumblefuzz: That is exactly what I just described [13:00] k ... think I got it [13:00] what does the "any" in "sudo ufw allow from 15.15.15.0/24 to any port 3306" mean? [13:01] why isn't it "sudo ufw allow from 15.15.15.0/24 to port 3306" ? [13:02] bumblefuzz: Because you can have multiple interfaces for network connectivity. Most desktops have an ethernet connection and what is called a loopback connection (accessible via 127.0.0.1). Laptops often have three connections, WiFi, Ethernet and loopback [13:02] the any means that any configured network connection will accept a connection to port 3306 [13:02] ah, it's the interface [13:04] thank you === Exterminador- is now known as Exterminador [13:09] so uhm… on contrast to linked questions… when i add modules to pulse default.pa (no matter if on /etc or ~) they wont get loaded (qpaeq: 'please make sure you have the pulseaudio dbus module loaded') activating them manually via pactl works fine though o.O https://askubuntu.com/questions/980876/how-do-i-start-pulseaudio-equalizer [13:09] https://askubuntu.com/questions/877485/how-do-i-find-out-what-pulseaudio-module-does-what#877499 === michele_ is now known as michele [13:39] hi. is there opensource free cloud file sharing app for linux like dropbox?

I don't want to have to change every cron job, or add MAILTO='' to every user's crontab on every server, is there another way, e.g. a config somewhere in the cron service? [14:03] oh i found their support channel here [14:03] sorry bothering you [14:04] B|ack0p: that just means [insert your URL here] [14:04] IP or hostname, of your machine [14:05] makr8100, hmm is it inet ip? [14:05] 192.168... ? [14:05] JediMaster: not sure... Is there a way to run sed on cron? I've never tried anything like that... [14:05] B|ack0p: yes [14:05] JediMaster: i haven't had a need to do this - if you like discuss what the background / greater need is there, and maybe we can find a better solution? [14:06] makr8100, these servers are chef managed, but changing the crontab in such a way isn't possible via Chef easily [14:06] ugh... I'm not familiar with Chef. No ssh? [14:06] JediMaster: if you'd instead just prefer to continue with your plans, i'd focus on reconfiguring the mail server / servers to write out a copy of these e-mails and drop them. [14:07] makr8100, Yes, SSH, Chef is used to manage the servers [14:08] tomreyn: these servers are often sending thousands of emails out per day, they end up going to root@somedomain.com based on the config of the webserver, this either annoys the person's domain or in some cases is getting blocked by mail relays like sendgrid (and taking up resources) [14:08] looks like you can run sed on crontab, that's what I would try [14:08] makr8100, Chef will then re-write the crontab back again [14:08] JediMaster: why do these servers send so much mail then? [14:09] oof... [14:09] tomreyn, because half of the cron jobs output some text when run, which then automatically gets emailed to root [14:09] and there's many jobs that run every minute, hence thousands of cron emails [14:10] JediMaster: and those users on these servers are not going to be massaged to change it? [14:10] There's a mixture of manually created and Chef managed cron jobs, yes, it's *possible* to > /dev/null every single one, but it's a huge job [14:10] JediMaster: this sounds like a VPS host environment or something? [14:11] yeah, they're webservers, the vast majority are automated cron jobs rather than user's own [14:11] JediMaster: i'd certainly dmanage it centrally, just on your internal / outbound mail servers. [14:11] I just want to stop cron from sending any out [14:11] Surely there's a central config or envrionmental variable that can be set in /etc/default/cron or something to stop it sending emails [14:13] JediMaster: your best solution is to bitbucket the output of the jobs as you already mentioned [14:13] apparently you can do this in /etc/sysconfig/crond on CentOS: CRONDARGS=-m off [14:13] JediMaster: there's /etc/default/cron which has since moved to the systemd service. [14:14] tomreyn, yeah I saw, but it's weird as the systemd file refers back to it: EnvironmentFile=-/etc/default/cron [14:15] JediMaster: which ubuntu version are you running there? [14:15] 18.04 [14:16] JediMaster, iirc should be MAILTO="" [14:16] ioria, can that be set globally, not just per user's crontab? [14:16] JediMaster, idk honestly [14:17] JediMaster: so /etc/default/cron is deprecated and will likely go away in the future. [14:19] tomreyn, That's what it looks like. Where should those arguments be set then? To me it looks like the variable here: ExecStart=/usr/sbin/cron -f $EXTRA_OPTS, however I can see where $EXTRA_OPTS is set [14:25] tomreyn, it seems if you set EXTRA_OPTS within /etc/default/cron it does indeed pass that on to the cron command, however -m off doesn't work lol [14:26] JediMaster: where do you see the -m option? [14:28] tomreyn, various references to cron on CentOS, however, I'm just trying MAILTO="" in /etc/default/cron to see if it reads the environmental variable [14:28] not there [14:28] JediMaster: this is #ubuntu, does centos even use vixie cron? [14:29] JediMaster, try in /etc/crontab [14:29] JediMaster: screw Chef, write a cron job to rewrite cron after Chef does it [14:29] ioria, it needs to be global to all cron jobs [14:29] for all users [14:29] JediMaster, that is global [14:30] tomreyn, hmm, yeah forgot there were different flavours [14:30] JediMaster, crantab -e (without sudo) is local [14:31] crantab? [14:31] crontab [14:31] k [14:31] yeah MAILTO="" in /etc/default/cron didn't work. I'll try /etc/crontab but don't think it'll apply to the user's cron jobs [14:31] JediMaster, restart cron maybe [14:31] ioria, Just did, but it's still sending emails out [14:32] JediMaster, ther redirect the output [14:33] ioria, I'm looking at many dozens of servers with anywhere from 5 to 30 cron jobs per user with 3-5 users per server [14:33] there are "cronic" and "cron-deja-vu" for fitering / limiting cron mail [14:34] tomreyn, yeah, but I'd rather stop them at source than filter them if possible [14:34] it's pretty close to source [14:35] you could also replace the cron implmenetation or have users make use of systemd-timers instead. [14:35] I suppose I could write a Chef recipe that checks through every crontab for every user to see that MAILTO="" is set, and if not adds it, but that's a pretty dirty hack [14:36] how do users edit their cron jobs? crontab -e? do they have administrative access? [14:36] Why doesn't cron on Ubuntu just let you disable sending emails? [14:36] tomreyn, yes, crontab -e, and a bunch are automated via Chef recipes [14:37] you restricted usrers run chef reciipes on your servers? [14:37] *your [14:39] tomreyn, The Chef recipes manage cron jobs for a selection of different users [14:40] Maybe I'm looking at this the wrong way, how about just disabling all local email to users, as none of them are actually in use, they just need to send email outbound === jmcgnh_ is now known as jmcgnh === jmcgnh is now known as jmcgnh_ === jmcgnh_ is now known as jmcgnh [14:41] JediMaster, i don't get it; If MAILTO is defined but empty no mail will be sent [14:41] ioria, the problem is setting that on every crontab for every user automatically across dozens of servers [14:41] i see [14:41] i guess the issue here is that there is no way to administratively enforce a usrs' MAILTO= setting [14:41] I can easily configure a central config file across all servers, but that is more difficult === jmcgnh is now known as jmcgnh_ [14:43] Chef actually gives you the ability to set the MAILTO on a per cronjob basis, but not for the entire user, so if the user edits their cronjobs beyond what is automatically set up, then those will send emails [14:43] I'm really considering just disabling local user's email now [14:43] as they don't need to receive emails, just send === jmcgnh_ is now known as jmcgnh [14:45] JediMaster: do you have per user storage accounting there? if so, i'd choose the opposite: force local delivery for all (restrictive) user generated crond mail [14:45] that'd make users want to fix their crontabs [14:46] (you'd still need to provide documentation and support, but that's already the case now since you allow them to use crontabs) [14:46] That's a good idea, but that would probably generate more work/support for me ;-) [14:49] not when you have good enough documentation (a one-time effort for the most part, cron doesn't change much over the years) you can always just point to ("help, my disk is full: because of mail") [15:42] hello [15:42] royalewithcheese, welcome [15:42] Thanks, lordcirth === ben_r_ is now known as ben_r [15:51] hello, LVM question: what should I do if 'lvs' lists some partitions as read-only, but in fact they aren't even in /dev/myVG/ ? [15:51] it looks like a bug [15:52] it lists that partition with `-ri-------` attr [15:54] pomeha: this is the output of running lsattr on something? [15:55] or lvs? [15:55] tomreyn: no, lvs [15:55] so it's just inactive [15:55] tomreyn: how to remove it? [15:56] remove what? [15:56] tomreyn: lv [15:56] you want to delete a logical volume? you'd use lvremove [15:57] by the way, "lvs" lists logical volumes, not partitions [15:58] tomreyn: tried that: https://paste.ee/p/Y6NdM [16:01] pomeha: which ubuntu version is this, which kernel version? [16:05] hello. if i want a minimal installation of ubuntu where i get my own window manager etc, which version do i get? [16:08] NickZ: ahh, I hadn't realized the process was short-lived. how did you manage to attach it before it dies? [16:09] sarnold: https://www.fossmint.com/which-ubuntu-flavor-should-you-choose/ [16:09] talin: on my most recent install I followed these instructions, which use debootstrap to get a *very* minimal install https://github.com/zfsonlinux/zfs/wiki/Ubuntu-18.04-Root-on-ZFS [16:09] I'd try to search by the wm you want, otherwise xubuntu is probably pretty good [16:09] talin: but be aware that it's *very* minimal, taking one of the other flavours may be easier :) [16:09] otherwise you could start with the server (cli only) edition and start adding to it [16:10] sarnold: cool, thank you [16:10] sarnold's way would probably be better if you're more advanced at things [16:10] I usually shoot for my preferred wm in the initial install [16:12] the desktop version has a lot of gnome stuf that i don't want [16:12] talin, https://www.omgubuntu.co.uk/2018/02/ubuntu-18-04-minimal-install-option [16:20] hmm, there seems to be a minimal CD as well === gtav is now known as rud0lf [17:09] has anyone had any luck integrating sssd-sudo with polkit? it's driving me nuts. user gets proper sudo rights delegation from AD via SSSD, but the Ubuntu UI just keeps asking for a local admin password [17:10] pretty much ALL google results talk about "add all such users to a hardcoded group" which is pointless and doesn't scale anywhere [17:11] doesn't even scale to more than 1 computer lol [17:12] you could probably use a makeshift stopgap like syncing that local group every 15 min [17:12] sync what group from where [17:12] and to where [17:12] to whatever active directory says (I guess you mean that with AD) [17:12] there's no group, to begin with. only sudoRoles. [17:13] bviktor, add it to /etc/polkit-1/localauthority.conf.d/51-ubuntu-admin.conf [17:13] and the problem is not group lookup anyway, group lookups do work. but it doesn't make sense making a separate group for each and every computer to specify the sudo users, THEN point ALL computers to the corresponding groups [17:14]
