hi, not sure if this should be here, in the installation/configuration area, or in one of the Linux areas, but I found the problem through ispconfig, and it affects ssh-user creation In ispconfig, so i'll post it here, feel free to move it if it's more relevant elsewhere. I found an issue with ssh-users whilst attempting a test migration from some ubuntu 16.04 servers to ubuntu 18.04 servers, I didn't know if it was an issue with migration, or something else, so in an attempt to isolate the problem more, I've installed a few different servers now, some standalone, some multi-server, all following the perfect server tutorial for ubuntu 18.04 (apache) https://www.howtoforge.com/tutorial...l-pureftpd-bind-postfix-doveot-and-ispconfig/ the jailkit service exits, immediately after starting, with logging showing 'no sockets specified in configfile /etc/jailkit/jk_socketd.ini on on commandline, nothing to do, exiting....' I've tried manually entering the config into the jksocketd.ini file Code: # example #[/home/testchroot/dev/log] #base = 1024 #peak = 10240 #interval = 2.0 [/var/www/clients/client766/web1824/dev/log] base=512 peak=2048 interval=10 and now jailkit will complain about no such file or directory /var/www/clients/client766/web1824/dev/log, then that no sockets are specified in /etc/jailkit/jk_socketd.ini and then exit if I manually create the folder /var/www/clients/client766/web1824/dev, and start jailkit, it'll start, and create the log socket. Code: ● jailkit.service - LSB: Start jk_socketd at boot time Loaded: loaded (/etc/init.d/jailkit; generated) Active: active (running) since Fri 2018-08-24 10:12:43 BST; 15s ago Docs: man:systemd-sysv-generator(8) Process: 28558 ExecStop=/etc/init.d/jailkit stop (code=exited, status=0/SUCCESS) Process: 28562 ExecStart=/etc/init.d/jailkit start (code=exited, status=0/SUCCESS) Tasks: 1 (limit: 2317) CGroup: /system.slice/jailkit.service └─28575 /usr/sbin/jk_socketd Aug 24 10:12:43 control systemd: Stopped LSB: Start jk_socketd at boot time.

Aug 24 10:12:43 control systemd: Started LSB: Start jk_socketd at boot time. and it seems that the /web1824/bin,etc,usr folders do get created eventually (seems to take a very long time) but the /web1824/home/<user> folder never gets created, and the create ssh-user job is stuck in ispconfig's job queue (currently been about 16 hours) it all works fine on ubuntu 16.04 and 17.10, I've tested it on multiple servers, and it's absolutely fine up to and including 17.10, but every 18.04 install I've done presents exactly the same problem. which is strange as the jailkit install instructions in the tutorials for 17.10 and 18.04 are identical. I don't know if anyone else has the same problem, and maybe just not noticed it yet, there's no evident problem until actually attempting to create an ssh-user on an 18.04 server.
