zolderHi, im currently setup an sftp server and ssh with a custom port etc.. its running from the inside and outside, only i dont know where i need to change the root directory where the sftp starts11:54
zolderwhen i login into it :)11:55
RoyKzolder: http://www.cyberciti.biz/tips/howto-linux-unix-rssh-chroot-jail-setup.html perhaps?12:11
RoyKzolder: if you don't use chroot, it should normally be secure enough anyway unless you do something exceedingly stupid12:11
RoyKzolder: using rssh is always a good idea for sftp if the users won't need full ssh access12:12
zolderi just use it for personal use12:20
zolderim confused by the man sftp-server12:20
zolderSubsystem sftp /usr/lib/openssh/sftp-server so that rule in my sshd.conf, do i need to put the -d command there ?12:21
RoyKzolder: sftp is enabled by default12:22
RoyKzolder: with all ssh servers12:22
zolderits running12:22
zolderbut when i login12:22
zolderi need to set a home directory where it begins12:22
RoyKzolder: default PWD after login is /home12:23
zolderso i was told to typ,  MAN sftp-server12:23
zolderso in the first line i read -D or -d12:23
zolderTo set my start directory12:23
zolderi want to set my staret directory to /var/www/downloads12:24
RoyKzolder: not sure, but I *guess*12:24
zolderand not to /home12:24
RoyKSubsystem sftp /usr/lib/openssh/sftp-server -d /var/www/downloads12:24
zolderyeah thats what i have to put in the rule then12:24
zolderi was not sure how to put it12:25
zoldersftp /usr/lib/openssh/sftp-server what does that part do then ?12:25
zoldercant i just delete that ?12:25
zolderso if i do Subsytem sftp-server -d /var/www/downloads12:26
RoyKzolder: you don't want two lines with 'Subsystem sftp'12:26
zolderno i understand12:26
zolderbut why do i need the first part of that subsystem12:26
RoyKI have this in my sshd_config12:26
RoyKSubsystem sftp /usr/lib/openssh/sftp-server12:26
zolder yeah me too atm12:27
RoyKjust add '-d /whatever' to that line12:27
RoyKmight even work ;)12:27
zolderI read on a tutorial that someone changed that line to sftp-internal or something12:27
zolderbut im not sure what it all is doin12:27
zolderto newb for that :P12:27
RoyKjust testet - works12:28
RoyKbut it doesn't chroot anything12:28
RoyKso if you need chroot, see the link above12:28
zolderis chroot something like chown ?12:29
zolderil click the link12:29
zolderchroot locks a user into  a directory12:30
zoldersounds legit12:30
zolderpretty complicated12:31
RoyKyeah, better lock users to /home or something and set permissions to only allow users to access their own dir12:32
RoyKchmod go-rwx /home/*12:32
RoyKor something12:32
RoyKthen you probably won't need chroot that much12:32
zolderchroot seems so much effort12:33
RoyKwe're not using it anymore for our servers, with 20k users ;)12:33
zolderit doesnt explain enough12:33
zolderwhy create the things and all the folders12:33
zolderits just like follow this and you will be ok12:33
RoyKzolder: because if something is chrooted, the actual process is also chrooted, and it needs access to some libs and devices etc12:34
zolderomg 20k users... so much fun to setup :P12:34
zolderbut i guess u use a script for that?12:34
RoyKfor what? the chroot thing?12:34
zolderso you create your personal root..12:34
RoyKyeah, something like that12:35
zolderlot of setting with that then12:35
RoyKand that makes it rather hard to break out of it12:35
RoyKzolder: better chroot users to just /home instead of $HOME - no need to have a chroot evironment in every homedir12:36
RoyKzolder: or just drop it - if file permissions are ok, there's no need to restrict things any further12:37
zolderso i type like chroot username:groupname and then ?12:37
RoyKchroot /somedir12:37
zolderand that applyĹ› to the user im logged into ?12:37
RoyKor yeah12:37
zolderhome is fine, only crap in there so12:38
zolderits just if someone gets onto my sftp i dunno how, but still12:38
zolderhe cant go to my systemfiles12:38
zolderjust to be a little bit more safe.12:38
zolderDo you suggest to put PAM on or off ?12:39
RoyKwell, they won't be able to read the important bits12:39
RoyKdisabling PAM is *not* recommended12:39
zolderand allowDNS off ?12:39
RoyKthe default config is fairly secure as it is12:40
zolderok good to know12:40
zolderi see people making a lot of changes on one say pam on or off, the other say something else12:40
zolderthe tutorials are not always clear12:40
zolderthanks man for helping12:40
RoyKif you're not a linux wiz, just don't touch anything you don't know ;)12:40
zolderthats what i want to do12:41
zolderelse i never learn it12:41
RoyKthen test in a VM12:41
zolderi try do to everything from the terminal12:41
zolderim 2 days in linux, and got a cups server, sambaserver, lamp server, sftp,12:41
RoyKthat's very wise12:41
zolderbut i all set it up by terminal12:41
RoyKvery good indeed :)12:42
zolder10 years ago i used a Distro called Trustix Secure linux, it was only terminal commands12:42
zolderi learned the command mdma that time12:42
zolderhad so much fun with that :), so thats why i picked it up again12:42
RoyKzolder: I've been using linux since late 1994 and even though I had a short period abusing webmin, I gave up on that rather quickly and went back to the commandline ;)12:44
zolderf you understand the cli12:45
zolderyou gonna understand linux12:45
RoyKyou will12:45
zolderthe dekstop is not doin much for me12:45
zolderbecause when people install stuff, and they used desktop and they find a problem, they cannot fix it, because they dont know how to use the console12:45
RoyKzolder: if you want to test things like chroot or with/without PAM with ssh, I'd suggest installing kvm/libvirt/virt-manager and creating a VM or two to test things there12:46
zolderi can install kvm on top of my mint ?12:47
zoldercan i make the VM bootable too so i start in fullscreen ?12:47
RoyKand install virt-manager - it's a GTK GUI thing for managing them12:48
RoyKzolder: no need, really, just install sshd on them and do the rest from there12:48
zolderi will look into that later i write it down12:48
RoyKapt-get install kvm libvirt virt-manager # ta-taa!12:48
zolderwhats the tataatata ?12:49
zolderjust a syntax after its installed?12:49
RoyK# is "comment symbol"12:50
zolderi know from the config files, but didnt know can use it this way hehe12:50
zolderhmm i cannot use chroot command12:54
zolderdo i need to be su ?12:54
zolderahh i need to use chown12:57

davidic654more rebbots I see14:49
RoyKmore rabbits14:49
davidic654when will Ubuntu stop the need to reboot twice a week14:49
davidic654my deb servers are like every 3 motnhs14:50
RoyKwhich version of ubuntu?14:50
davidic65412.04 and 14.0414:51
RoyKdavidic654: ubuntu usually requests restarts after kernel or libc is updated14:51
RoyKdavidic654: with 4.x kernels, automatic kernel upgrades will be dynamic (when that work's done), so you won't need a reboot14:51
davidic654any way around these frequent reboots, I manage upto 50 servers and its a pain14:51
RoyKbut for libc, you'll need to restart most processes (or all) meaning a reboot is easier14:52
davidic654less reboots is a great selling point I would have thought14:53
RoyKdavidic654: even if ubuntu requests a reboot, check /var/run/reboot-required.pkgs14:53
davidic654less reboots and a great EOL and its a winner :)14:53
RoyKseems my old 12.04 server has a bunch of new kernels :P14:54
pmatulismeekrat: https://help.ubuntu.com/14.04/serverguide/sssd-ad.html14:55
RoyKI'm also waiting for this http://www.zdnet.com/article/no-reboot-patching-comes-to-linux-4-0/14:55
RoyKpmatulis: it works without sssd too14:56
davidic654yeah its an obvious issue they are looking at14:56
davidic654ty for that RoyK14:56
davidic654less than ever ;)14:57
davidic654its like twice a week with Ubuntu at the mo14:57
davidic654One reason to love Linux on your servers or in your data-center is that you so seldom needed to reboot it :) Really14:58
davidic654I like Ubuntu because of its great EOL and compatibility with the CP I use for clients, but sod these frequent reboots, hope all improves soon14:59
davidic654apt-get update apt-get upgrade apt-get autoreove apt-get autoclean reboot, story of my life at the moment :)15:01
davidic654the 5 commandments :)15:02
davidic654see you sorted the grub timeout issue with headless servers, well done15:04
davidic654just in libxml2 vulnerabilities, needs reboot, geeeeez15:06
davidic6543 hours of my life gone tomorrow15:06
mdeslaurdavidic654: there's nothing special about ubuntu that would require more reboots than any other linux distro15:09
mdeslaurdavidic654: it's pretty much only kernel updates15:10
davidic654I use Debian and Ubuntu but Ubuntu reboots are over the top15:10
davidic654Ubuntu has a lot more kernel updates15:10
mdeslaurdavidic654: if you're fine with waiting three months between kernel updates, then just reboot every three months15:11
mdeslaurdavidic654: we publish kernel updates pretty much every three weeks15:11
davidic654actually can I ask a Q I have a few servers with hetzner and I never have a kernel update just the dev part is that normal?15:12
davidic654they running a special kernel or something15:12
mdeslaurdebian does a kernel update every 4-6- weeks15:12
davidic654I mean for security reasons, so and so found tthat etc15:13
mdeslaurdavidic654: sorry, don't know anything about hetzner15:13
davidic654all my kernel updates are because of security15:14
davidic654so and so found etc15:14
mdeslaurso ubuntu only has about 1.5 more kernel updates than debian15:15
davidic654I guess the expoits are very sophisticated but I like to keep servers secure15:15
davidic654maybe I worry too much15:15

jpdsdavidic654: Looking into the issue?15:31
davidic654the new kernel15:31
davidic654I think reboots are annoying a lot of people15:32
jpdsYou know that you don't HAVE to reboot when you get a new kernel?15:32
davidic654for security issues?15:32
jpdsYou can look at the changelog and see what exactly has changed15:32
RoyKdavidic654: use && between them15:33
davidic654why does Ubuntu say that you have to reboot for the changes to take effect15:33
jpdsIf all that's changed is that some kernel module that you never use, you don't need to reboot15:33
RoyKdavidic654: libc changes makes you have to restart all processes - kernel changes makes a reboot needed unless you use some hotpatching thing15:34
davidic654its always a security thing tho15:35
RoyKdavidic654: mostly "reboot required" only means "it would be nice for a reboot because some things may have changed"15:35
RoyKdavidic654: https://xkcd.com/1328/15:36
RoyKdavidic654: see the mouseover ;)15:37
davidic654USN-2803-1: Linux kernel vulnerability is specifically for KVM hypervisor for eg, so you only need to update the kernel if running that15:37
jpdsdavidic654: Exactly15:38
davidic654got it15:38
davidic654geez now I can go on holiday :)15:38
RoyKdavidic654: you'll get an email tomorrow that a new critical fix is on the way :D15:39
davidic654maybe Ubuntu should say if its a core file or something??15:39
jpdsdavidic654: Define core file15:42
davidic654minimal install?15:42
jpdsdavidic654: The whole kernel's part of the minimum install15:42
davidic654I just run webservers15:42
davidic654I think I may have been rebooting for things not on my servers maybe15:43
davidic654so maybe my fault15:43
jpdsdavidic654: Some obscure kernel module that it's used by a network card may be core for someone, but maybe not for me and you15:43

=== roo_ is now known as roo
sarnoldSCHAAP137: you can use an .override file for the upstart configuration to change the 'start on' line; you'd need to make sure that the service that sets up the ipv6 addresses emits a signal of some sort, or you 'manually' emit the signal yoursellf, see http://upstart.ubuntu.com/cookbook/#ordering and some of the following sections for a better sketch of this18:32
SCHAAP137cool, i will read that, thanks sarnold18:33
SCHAAP137i'm just using /etc/network/interfaces to set up the addresses18:33
sarnoldhmm, it feels like that should work better :/18:34
sarnoldteward: around? :) ^^^18:34
SCHAAP137i'm assigning one address statically, and use 'up /sbin/ifconfig eth0 inet6 add [addr]' twice within that same block, for adding a few extra ones18:36
SCHAAP137the nginx error is about one of those18:36

sarnoldindeed, no :)18:41
SCHAAP137restarting ssh service from there as well, because tun0 and tun1 aren't up yet when ssh starts18:41
sarnolda better workaround, if a proper fix is just too hard to get working, is to use the 'manual' method of starting it, and then keep your /etc/rc.local change to -start- nginx, rather than restarting it :) that at least saves a useless start and stop18:41
