Interesting, I configured this to update every minute. The output is 5 minutes:
root@LinuxHippy:~# noip2 -S
1 noip2 process active.
Process 702, started as noip2
Using configuration from /usr/local/etc/no-ip2.conf
Last IP Address set 141.158.41.50
Account
kingskid@juno.com
configured for:
host linuxhippy.no-ip.com
Updating every 5 minutes via /dev/eth0 with NAT enabled.
It seems to be configured correctly. My router's firewall is not on now-hopefully it'll keep running smoothly when my IP address changes next-I'll let people know here.
Verizon DSL has said twice that it is ok for me to run an ftp server from my house using residential DSL. They offered no tech support as to how to do this. I was told last week that my IP address would probably change daily by the networking guy at work-mine is every 2 or 3 days. I think the rules must vary from state to state and IP to IP for dynamic IP addressing.
