You can even use non-127.0.0.x addresses (lines wrapped to fit in 80 columns): % gothmog:/root# ifconfig lo1 plumb % gothmog:/root# ifconfig lo1 10.6.0.1/24 up % gothmog:/root# tcpdump -s 100 -i lo1 -qvlnn & % [1] 23432 % tcpdump: listening on lo1, link-type NULL (BSD loopback), % capture size 100 bytes % gothmog:/root# ping -c 2 10.6.0.1 >/dev/null 2>&1 ; sleep 01 % 22:02:01.823069 IP (tos 0x0, ttl 64, id 5813, offset 0, flags [none], % length: 84) 10.6.0.1 > 10.6.0.1: icmp 64: echo request seq 0 % 22:02:01.827119 IP (tos 0x0, ttl 64, id 5814, offset 0, flags [none], % length: 84) 10.6.0.1 > 10.6.0.1: icmp 64: echo reply seq 0 % 22:02:02.833529 IP (tos 0x0, ttl 64, id 5827, offset 0, flags [none], % length: 84) 10.6.0.1 > 10.6.0.1: icmp 64: echo request seq 1 % 22:02:02.833568 IP (tos 0x0, ttl 64, id 5828, offset 0, flags [none], % length: 84) 10.6.0.1 > 10.6.0.1: icmp 64: echo reply seq 1 % gothmog:/root# ifconfig lo1 unplumb % gothmog:/root# _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
