Monitoring Network Traffic With IPTraf Sep 22, 2008, 22 :32 UTC (0 Talkback[s]) (3145 reads) (Other stories by Juliet Kemp)
"One of the best points of iptraf is its flexible traffic-filtering options. In the Add Filters screen, the left-hand set of filters are for the source address; the right-hand for the destination. A value of 0.0.0.0 for IP address and netmask translates to "all hosts." The I/E at the bottom control whether matching data is included or excluded."
