I'm trying to set up one of our lab machines as a PPP server. I've successfully gotten to the point where a serial connection is established and ip numbers are established. However, I am unable to ping the server host from my home machine. I suspect a routing problem, but the routing table on the client looks okay (there is a default route to ppp0). I don't know how to check what is happening to the ping packets, since they appear to be transmitted.
One possible bit of complexity is that the server machine has two ethernet interfaces and does ip-masquerading for a small subnet. Also, I can't seem to remove the arp table entry for the ppp interface: ----------------------------------------------------------- laplace:/etc/ppp# arp -d euler.statmech SIOCDARP(pub): No such file or directory euler.statmech (192.168.1.3) at * PERM PUP on eth0 euler.statmech (192.168.1.3) at * PERM PUP on eth1 Here are some of the specifics: ----------------------------------------------------------------- I have dpkg package ppp version 2.3.5-2, and have compiled ppp support into the kernel 2.2.10 (not as a module).
