That's not a bad solution, but you might consider an alternative: give
your host a hostname at http://www.dyndns.com (a free service), and use an
update client to call in to dyndns.org whenever the IP address changes. I
use ipcheck, but there are lots of update clients-- dyndns.com has a list
of compliant ones.
I've heard of such things but the host is behind a firewall/router. I
found it easer to go to whatismyip.com. The perl script took me about an
hour.
Huh? When ip-up is called (for new connection, IP may change), you
get these:
# environment vars:
# DEVICE
# IFNAME
# IPLOCAL <<== new IP number ;)
# IPREMOTE
# PEERNAME
# SPEED
# ORIG_UID
# PPPLOGNAME
# CONNECT_TIME
# BYTES_SENT
# BYTES_RCVD
# LINKNAME
# DNS1
# DNS2
There's this concept: event triggered programming, much better than
polling ;)
