Hi,
I've posted som messages two weeks ago about strange outgoing packets
(with local IPs 127.x.x.x but never 127.0.0.1 and seemly random
destination addresses).
I didn't had this during some few days but now it happens again every
evening (never at the same time).
Trying to find what occurs, I run tcpdump all the night and netstat and
ps every 5 minutes. I can't see anything but normal operations with
netstat and tcpdump. But ps gives me strange things :

318 16225 318 318 ? -1 S 99 0:00
/usr/local/apache/sbin/httpd
So, as you can see, I have a normal httpd daemon (apache) that runs as
user nobody and a lot of strange httpd entries that run as root and that
take far less memory than the normal daemon.
Normal httpd daemons are launched by process 318 but non normal httpd
are launched by... 353 which is... kswapd !!!
And I have two kswapd processes (launched by init). Is it normal with a
2.2.12 kernel ??? kswapd isn't supposed to launch processes isn't it ???
Could someone with a 2.2.12 kernel send me the result of a ps ?
Could it be a kind of trojan ?
Thanks for any help.
Fabrice.
