Hello everyone,
I just started experiencing a problem I cannot diagnose on
my humble 3.1-RELEASE box. FYIW, it was working fine
since Nov.
The machine is on a Novell 4.x intranet. I have network
connectivity to the machines on the same subnet.
I occasionally dial out with user ppp. I get my IPs
dynamically from my ISP but I have actual addresses for
primary and secondary DNS.
Starting about the middle of last week, I'm not able to
"route" through the ppp connection. I cannot telnet,
ping, or ftp to any machine on the internet, even the
dial-up server I just connected to!
When I do a netstat -r, it takes forever to return.
However, a netstat -rn returns immediately.
Here's all the miscellaneous configuration files involved.
I've tried to figure it out all on my own, but have
reached the end of my abilities.
