RE: [Sheflug] Printer sharing, NFS and ADSL IP addresses.

I've had a cable modem from NTL for about 6 weeks now, for this I get a
Dynamic DNS that relates to the original IP address supplied. The DHCP lease
if set to 4 hours, however I am still using the original IP address.
Everything seems to work well, My interface if Ethernet which is far
superior to the BT offering of PPP over ADSL, and there are no USB interface
problems.
