Hi y'all,

Following is my situation:
- Running Suse 8.0 out of the box
- Recognizes my ISDN hardware
- I'm able to dial in with provider
(log shows connection OK)
- BUT:

- Even a simple PING does not work

Anyone know solutions or directions to FAQ?

BTW: XP Professional (indeed :-) works fine with this hardware...

--------------------------------------------------
Never mind the Bear, beware of Papa!

Try "ping 128.83.139.9".

o If ping just hangs "forever" then it's likely that the default
route is wrong. If there is an existing default route then pppd
won't replace or override it, even with the defaultroute option.

In most cases, an existing default route is unnecessary and the
right solution is to remove it. Otherwise you can add

/sbin/route add default $IFNAME

to /etc/ppp/ip-up. Pppd runs the script ip-up with a particular
set of environmental variables (see man pppd) and IFNAME contains
the name of PPP interface.

o If ping exits with a "Network is unreachable" message then it's
likely that isn't any default route to the Internet - perhaps the
pppd defaultroute option needs to be added.

o If ping works as expected then it's likely that there is a DNS
name server problem. Read on.

Try "ping cs.utexas.edu".

o If ping exits immediately with a "unknown host" message then it's
likely that no DNS name servers are configured in /etc/resolv.conf.

o If ping hangs for a short time before exiting with the same message
then it's likely that either the configured name server IP addresses
are wrong or the name servers are not functioning.
