Ssh into nodes
SSH has a whitelist system for sshing; only people who are on it can ssh into the nodes if
AllowUsers jw279 pjt6
has been added to
/etc/ssh/sshd_config.
This is great and stops people ssh-ing into nodes, but also stops qrsh into nodes. This is because we use ssh to connect.
qconf -sconf
shows this in the lines
rsh_command /usr/bin/ssh rsh_daemon /usr/sbin/sshd -i
From [1] changing
rsh_command /usr/bin/ssh
to
rsh_command /usr/bin/ssh -i -f /etc/ssh/sshd_qrsh_config
should work if we add the AllowUsers line to sshd_config and have an identical copy of it without this line called sshd_qrsh_config.
It doesn't though and I can't work out why.
