[slurm-users] IPv6 for slurmd and slurmctld

[Jeffrey T Frey]

Use netstat to list listening ports on the box (netstat -ln) and see if it shows up as tcp6 or tcp.  On our (older) 17.11.8 server:


$ netstat -ln | grep :6817
tcp        0      0 0.0.0.0:6817            0.0.0.0:*               LISTEN  

$ nc -6 :: 6817
Ncat: Connection refused.

$ nc -4 localhost 6817
^C
