[07:22] <lordievader> Good morning
[10:46] <flowinho> Hey there 👋
[10:46] <lotuspsychje> !security
[10:46] <lotuspsychje> start here flowinho
[10:46] <flowinho> thank you lotuspsychje
[10:48] <lotuspsychje> flowinho: maybe if you share your specific purpose and services, volunteers can try to help you more specificly
[10:50] <lotuspsychje> flowinho: personally i also reccomend nmap your own ip aswell, to see how the outside world sees your server ports
[12:15] <vlm> is there any use of copying /etc/passwd and /etc/group file from / into a chroot when chrooting?
[12:18] <vlm> thing is,when i make a file using ssh like so : echo file|ssh user@chroot-host "cat > myfile" that file gets the proper owner regardless of presence of passwd and group file
[15:45] <locknet> #reddit-sysadmin
[15:46] <Maik> stop spamming
[15:46] <locknet> Maik, sorry, not trying to spam
[15:47] <locknet> trying to join a channel but hex cut my command
[15:50] <Maik> oh, ok :)
[17:34] <lordcirth_> I just rebooted a prod 16.04 server after way too much uptime, and now lxc-* commands are all hanging, and no containers will start. Looking at htop, I see [lxc monitor] in "D" state. Help?
[17:37] <lordcirth_> kill -9 of the hanging process kills the hanging command, but then the next command just hangs again
[17:41] <rbasak> D usually means blocked on I/O
[17:42] <rbasak> Do you have filesystem corruption or some kind of disk fault?
[17:42] <lordcirth_> Not that I can see, but I will check again
[17:43] <rbasak> NFS hang?
[17:43] <lordcirth_> rbasak, there are no IO errors in dmesg; some of the containers depend on cephfs, but not all, and the cephfs mount seems fine
[17:44] <lordcirth_> (it's only used for homes, not /)
[17:44] <rbasak> I don't know then, sorry.
[17:45] <rbasak> It does seems like too much of a coincidence that you're using cephfs and you (superficially) appear to have something blocked on I/O though.
[17:45] <rbasak> I would exhaust that avenue first.
[17:47] <lordcirth_> In the past, any cephfs error has been accompanied by tons of dmesg errors
[17:47] <lordcirth_> I will tried to revert kernel but grub-reboot didn't work
[18:36] <lordcirth__> rbasak, I rebooted with the cephfs mounts commented out and it still hangs. Trying now without nfs as well, but I'm not hopeful
[19:45] <lordcirth> Ok, so lxc-net is hanging on an iptables --wait command; but I have no idea why the iptables command is hanging. Maybe something else is hanging on the lock?
[20:00] <znf> strace it?
[20:01] <lordcirth_> znf, was that to me? (sorry, I keep reconnecting)
[20:01] <znf> yes, strace the iptables? :)
[20:03] <lordcirth_> I tried, it's just a wait4( that doesn't seem helpful... I don't use lxcbr0 anyway, so I am trying USE_LXC_BRIDGE="false" and rebooting
[20:13] <lordcirth_> Most of the containers have started now...
