Ok, so there is a openssh audit-patch that breaks if you compile a kernel with out certian features. VPS are notorious for this.... Downgrading ssh works.. but who wants to downgrade something like that?

The most recent update of openssh needs the following enabled in the kernel:

CONFIG_AUDIT
CONFIG_AUDITSYSCALL


The reason for this is.. they introduced a new patch that requires this...

This:

root@ns3 [~]# w
20:51:58 up 43 min, 0 user, load average: 2.24, 0.47, 0.14
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
root@ns3 [~]#

Turns into this:

root@ns3 [~]# w
21:03:57 up 1 min, 1 user, load average: 2.07, 0.59, 0.20
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
root pts/0 24-180-48-16.dhc 21:03 0.00s 0.02s 0.01s w
root@ns3 [~]#
