Subject: weird problem

Hi folks,

I'm having weird problems getting cipe to work for one of my remote users.
I am able to get cipe to work just fine over dialup, but when I switch
configs over so that cipe starts on eth0, the cipe interface just kind
of doesn't work. I know that it's trying to:

The ISP swears up and down that they do not do any traffic filtering, but it
seems like they modify icmp:

root@somehost /root]# ping www.redhat.com
Warning: no SO_TIMESTAMP support, falling back to SIOCGSTAMP

This is the first time that I've seen this. Does anyone have any idea
what is going on?

Thanks in advance!
