Hello guys, I've found that a Fedora Core 5 server Kernel 2.6.15-1.2054_FC5, is doing port scans, and we hace received complains about that, the extrange connection that I've found is this one:
Netstat Oupput:
tcp 0 65 192.168.200.8:45436 194.109.20.90:6669 ESTABLISHED 1925/bash
Everytime that I kill the procc, it gets connected again in 30 secs, so I've don this:
IPTABLES ACTION:
2. I've done this on the server as a countermeasure
iptables -A OUTPUT -d 194.109.20.0/24 -j DROP
Thanks a lot for your advices
