RESOLUTION
Users logged in a VE via ssh are not showing up in w/who commands.
This is related to PAM authentication. Virtuozzo kernel does not support audit.
sshd in Redhat AS4-u3 (CentOS 4.3) is trying to connect to kauditd socket using NETLINK.
This operation fails and thus sshd is not adding the record to utmp.
It is a bug in Redhat's patch to sshd.
As a workaround you may set the following settings in /etc/ssh/sshd_config:
UsePAM no
UseLogin yes After that you need to restart sshd:
/etc/init.d/sshd restart Keywords: w who audit ssh PAM authentication
