I suppose you could make up some iptables rules that logged connections to the NTP ports. e.g. iptables --append INPUT --jump LOG --protocol udp --destination-port ntp --log-prefix "firewall{NTP}: " But, if you have other rules generated beforehand, you'd might have to insert rather than append. You'd find something with lines beginning with "firewall{NTP}:" in your /var/log/messages file for accesses to that port. -- [tim@bigblack ~]$ uname -ipr 2.6.22.4-65.fc7 i686 i386 Using FC 4, 5, 6 & 7, plus CentOS 5.
