Thanks Paul.

I still have (partial?) root access. Logs show china9988 at 21cn.com trying
to relay through smtp port, which leads me to think that it's either a
diversion, or I rehashed aliases.db before that part of the compromise
was complete (highly unlikely, invisible shell access should be able to
overcome that). NMap shows ports open for WMS and RTSP, which I've yet
to figure out how to close.

You mentioned making it more difficult?

Any insight is appreciated.
