Nope, that's the way to go. I'd deposite some very small cgi-bin on some
webserver, eg this one:
#!/usr/bin/perl
print Content-type: text/plain\n\n;
print $ENV{REMOTE_ADDR};

The ``ifconfig'' command will show the information for one or all NICs on the system including the private IP address assigned. Checking on an external site will only show you the public IP address of the box doing NAT.

finding the ip address
I'm messing with ubermon for superkaramba and I want to know how to get my hosts ip address from the command line (and only the ip address). I know I can grep and sed rc.conf or the output of ifconfig, but I'm hoping there's a command like whoami for the ip address. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

There isn't anything that simple, but munging the output of ifconfig is what
you want. This assumes that your box only has one IP address (other than
localhost):
# ifconfig -a | grep inet | grep -v 127.0.0.1 | awk ' { print $2 } '
192.168.0.4

But, for simplicity, if you are on a public host:
$host `hostname`
might do it...

Thanks for the info.
I modifies your solution slightly, so I could use it for more interfaces
easily.
ifconfig dc0 | grep inet|awk '{print $2}'

Doh! You'd still have to deal with some text output,
though. Sorry.

if your host use DHCP - you may add something to your dhclient.conf and
make some script to record it's IP.
