A tool to passively "tap" UDP sessions and send the traffic to another host.
Options:
-i <interface> Interface to tap
-u <port> UDP port to tap
-d <host> Destination host
-p <port> Destination port
The following example will sniff syslog packets off eth0 and resend them to port 514 on somehost where a syslog server may be listening.
./udptap -i eth0 -u 514 -d somehost:514
