Check out /etc/security/limits.d/ too.
Very helpful hint, but there is just a file
20-nproc.conf. Its all commented out:
#* soft nproc 4096
#root soft nproc unlimited
Why are you sure, that it's something about the limits?
What do you see actually?
Very easy: Using
#* hard nofile 65536
in limits.conf I can login as root via ssh. With
* hard nofile 65536
ssh logins as root don't work. Sample session:
# ssh lxc1
Last login: Wed Nov 25 11:00:21 2015 from linux.example.com
Connection to lxc1 closed.
#
The system log shows
Nov 25 11:08:58 lxc1.example.com sshd[186]: pam_limits(sshd:session):
Could not set limit for 'nofile': Operation not permitted
Nov 25 11:08:58 lxc1.example.com sshd[186]: pam_unix(sshd:session):
session opened for user root by (uid=0)
Nov 25 11:08:58 lxc1.example.com sshd[186]: error: PAM:
pam_open_session(): Permission denied
The documentation for limits.conf states clearly that a wildcard
construct like
* hard nofile 65536
does *not* apply to root. IMHO it shouldn't fail.
Now I understand, what your problem is. I thought, you're still not able
to login.
Yes, it's a known issue. There are other similar limitations too:)
