OMG. I suggest it’s python problem. Because /usr/sbin/univention-ssh it’s python script and you can reproduce your error if launched univention-ssh with options “pwd_file user@host command”

#5

@zakabluk should i reinstall python ?
The server is updated to the latest patchs

#6

Tell me pls your OS and python version.

hm, looks nice. I used iso image ucs same version, yesterday. And did join without problems. Maybe reason on master node ? Maybe you can found errors in master node logs(join.log)?

#9

@zakabluk i have more slaves and both are working ok.

This new slave is a VM running over xcp-ng (xenserver) but have resources… two things that i notice in the slave is the cpu high usage (mainly smbd process) and sometimes i get pkgsql errors in logs, that isn’t configured…

So i have a lot of issues with this server i can’t find the reason…
