I successfully ping'ed using and IP address rather than a name. The
first response of the ping returned no data, but that was obviously
due to the PPP connection not being completed.
ping 207.69.200.129
PING 207.69.200.129 (207.69.200.129): 56 data bytes
ping: wrote 207.69.200.129 64 chars, ret=-1
64 bytes from 207.69.200.129: icmp_seq=29 ttl=58 time=180.1 ms
64 bytes from 207.69.200.129: icmp_seq=30 ttl=58 time=170.0 ms
64 bytes from 207.69.200.129: icmp_seq=31 ttl=58 time=160.0 ms
I also edited the resolv.conf, which is now:
search mindspring.com
nameserver 207.69.188.185
nameserver 207.69.188.186
Unfortunately, adding "search mindspring.com" did not solve the problem.
That is, when I simply type, "ping pop.mindspring.com" I still get:
ping pop.mindspring.com
ping: unknown host pop.mindspring.com
When I then re-enter "ping pop.mindspring.com" I receive return data.
I don't seem to be negotiating DNS on the first connection attempt with
demand dialing.
Does demand dialing simply not work?
Any ideas for options or troubleshooting?
Thanks for the help,
Barry Mathieu
