su - news

say: # su - news This account is currently not available. but, thinking... /etc/shadow contain news:!:(...) Am I right saying than the "!" mean no login is allowed with a password? in fact, I ask because in Yast, in the system user news account, there are "****" in the password field. But may be these are only place holders... so may be I can remove the "nologin", but keep using no passwd. like this I could go to user news account and identity with su - from root, add a ssh rsa key and then log in the ~news account with the corresponding ssh key? thanks jdd -- http://dodin.org https://valeriedodin.com

But what definitely works is "sudo -u news -s /bin/bash". It will give you interactive shell.

ok, very good, it's really the simpler solution. thanks!! jdd -- http://dodin.org https://valeriedodin.com

There's a -c missing. (ls is not a script file so bash won't run it as one). Try

# LANG=US ; sudo -u news -s /bin/bash -c ls

ok, thanks still learning at 75' :-) jdd -- http://dodin.org https://valeriedodin.com

curious, the result is not exactly the same (not same prompt) #sudo -u news -s /bin/bash news@ns507557:/root> exit news@ns507557:/root> whoami news ns507557:~ # su -s /bin/sh news sh-4.4$ sh-4.4$ whoami news jdd -- http://dodin.org https://valeriedodin.com

Why do you expect bash and sh to have the same prompt?

Perhaps because /bin/sh is a symlink to bash? But he is using sudo once and su another time. I can not verify because on my machine user "news" can login. -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.2 x86_64 (Minas Tirith))

Uh, try "su -s /bin/sh --login news" It's the same as "su -s /bin/sh - news" -- Per Jessen, Zürich (9.9°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland.
