We're running linux with the 2.0.38 kernel, using a D-Link NE2000
compatible ISA network card. We're connected to a Cisco 2500 series
router on a frame relay connection. We're not running a firewall.
We can't ping or traceroute anywhere, not even the localhost. It's like
all icmp traffic is being blocked. Everything other than icmp
to the internet and the localhost such as telnet, mail, etc, work just
fine. I've tried upgrading the kernel and that didn't fix it. We've
tried changing out the network card, and that didn't help either. I
haven't been able to get tcpdump to work, so I'm not sure how to
it from here. We tried bringing the system down to single user mode
nothing but networking started, to see if perhaps something else was
interfering with it but no luck there either.
This just started happening one day a while back for no apparent reason.
No changes had been made to the system that we're aware of when it
Please e-mail me any suggestions you might have.
Thanks so much,
