Hi,

anyone cares to explain a bit on this /var/log/messages ?

13:45:46.207280 > callisto.9999 > crux.9999: udp 104
13:45:46.540309 < crux > callisto: icmp: crux udp port 9999 unreachable

Which port is now unavailable ? How can somone in linux check if a port is
available ? By doing a telnet on it ?

Thanks !
