Oops. Sorry. | | I should have been clearer: | | I believe that the proxyarp flag causes the pppd to go beserk and | consume lots of processor time for no apparent reason.

The fact that the proxyarp flag doesn't work, and is common in | both these situations makes me suspicious. | | The friend also despaired of pppd not hanging up cleanly, and hacked | together a script which ping'ed the remote end every so often and | killed the pppd if it didn't reply. A hack, but it work(ed). Apparently you're right that it's the proxyarp option. I disabled it, and the CPU load was gone. The pppd hangs up cleanly now as well. Only problem is that there's no arp entries made on logging on, which disables all outside-access for those hosts. We've created a ip-up script which looked like this: #!/bin/sh # # interface tty speed localip remoteip arp -s $5 0:0:1c:6:1e:d2 pub I guess you can imagine what this SHOULD do. As a matter a fact, it doesn't do anything. We've checked if it's excecuted, and it does excecute all right. There's no apparent cause why this shouldn't work, but it doesn't work all the same. Any clues ? :-) - Rob. /*--------------------------------------------------------------*\ /* Rob Simons | rob@simplex.nl *\ /* ------------ | ------------- | -------- | ------- *\ /* Novell Netware System Operator | UNIX system operator *\ /*--------------------------------------------------------------*\
