It only occurred to me after I had posted that you might be interested in what IP you were presenting to the world, and not just what addy was assigned to the local interface. However, ifconfig, which Windows has "M"-ulated (immolated?) with "winipcfg" and the even more sinister "ipconfig," will tell you lots about all the system interfaces when used with the -a switch, ie: #ifconfig -a dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.2.103 netmask 0xffffff00 broadcast 192.168.0.255 inet6 fe80::2a0:ccff:fe25:9347%dc0 prefixlen 64 scopeid 0x1 ether 00:a0:cc:25:93:47 media: Ethernet autoselect (100baseTX <full-duplex>) status: active lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3 inet 127.0.0.1 netmask 0xff000000 ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500 sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552 faith0: flags=8002<BROADCAST,MULTICAST> mtu 1500 As you see from this example, this host is on a LAN at 192.168.2.103... I assume, if you're using dialup, that the IP addy would appear in the ppp0: section.... "arp -a" is going to give you information about more machines than just your own, quite possibly. I'd use this instead: #arp -n your.hostname.tld your.hostname.tld (11.22.33.44) -- no entry HTH, Kevin Kinsey To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
