You could use
tcpdump or if you have a gui installed use
wireshark.
If you're brave you could write some
iptables rules and
tail -f on
/var/log/syslog
Code:
iptables -I INPUT -s remote.host.ip.1 -j LOG --log-ip-options
iptables -I OUTPUT -d remote.host.ip.1 -j LOG --log-ip-options
Also make sure that the services are listening on the outbound interface and not localhost. Use
netstat -tulpn to see where and which process are listening.
