Do a `netstat -ran' to see everything in the table. The `-a' requirement was added because some people felt that this was too much transitory information to print at one time; in retrospect, this may turn out to have been the wrong choice (particularly when the `-n' flag is being used). > I tried pinging his endpoint address '199.84.157.21', > and got no response.

I believe this problem to have been fixed in the -current; you can work around it in the meantime by doing a forcible `route delete -host xx.yy.zz.aa', but if your machine is busily trying to send IP to the other end when you do this, then the route will get recreated almost immediately. If you look at -current in net/route.c:rtrequest(), there is some code (and a big comment) below the `makeroute' label which attempts to handle this case. It should patch cleanly into your system. -GAWollman -- Garrett A.
