I have a friend, here is what he sent me:

- The box is cracked. A whole raft of functions in /usr/bin and /usr/sbin
were replaced with newer/older versions. The reason I say it that way is
that the file stamps are newer but, the reported version numbers are
older.
- The NIC is in PROMISC mode. If you run ifconfig and look at the NIC
flags 'PROMISC' appears there. When I turn it off it is only a matter of
moments before it is back on. This is another clue that I'm cracked.
- When I run tcpdump the amount of traffic is staggering!! In fact, I
thought I might win if I closed things down a bit...and subsequently
closed the door on myself. I'm sure that noone is using the box at the
moment. :-)
- I went out and grabbed real versions of all of the RPMs for the tools
that were replaced. I forced those to install overtop of the cracked
ones. That worked...until some process re-copied the bogus ones on top
again.


Any suggestions (other than turn the machine of and repave the system)?

I'm trying to help him find the source of the problem.  In trying to limit
net access to the machine, he ended up locking himself out til he gets
home from work.

in order to figure out what processes are running, and which one might be
causing the mayhem, I basically suggested he try this:

more /proc/*/cmdline

which should list the processes running better than a cracked `ps`.

any help is much appreciated.

Dave
