1 - if you aren't sure, then take it off the net untill you are sure.
2 - view the log files in /var/log
3 - look at the contents and the file dates... see anything "not rigt"
I haven't spent much time in /var/log before unless I was looking for
something specific so it all looks pretty foreign as I look over it
now. What type of things should I be looking for?
4 - from a "rescue disk" of some merit and run chkrootkit or simiar tool.
Here is the output of chkrootkit. It looks fine to me but there is
some stuff at and near the end that I don't understand.

5 - did/are you running any internet services? Look at their log files with a
magnifying glass for "any" discrepancy...
I am running bittorrent on the affected machine as of yesterday with
tcp and udp ports 6881:6999 forwarded to that machine from the
firewall/router via shorewall. Here is the shorewall config.
/etc/shorewall/zones:
fw firewall

/etc/shorewall/interfaces:
net eth0 detect tcpflags,routefilter,nosmurfs,logmartians

$FW net REJECT info

/etc/shorewall/masq:

Please let me know if you have any further advice. I'm completely
puzzled as to what happened to the contents of ~/vmware.
