I load-test ppp by running it over loopback connections via inetd (for example when I was testing the dynamic IP assignments). I was aware of a rather strange limit on 100 ppp processes ! I've now found that the problem is that the ppp code is assuming an interface name to be up to 5 characters *blush*. I've just fixed this (in -current), but I can't currently build the archive on http://www.FreeBSD.org/~brian 'cos of recent libalias problems :-( It'll be in the next (post 980108) version. Having said all that, I've never actually used these 100 connections all at the same time. I may try soon :-) > John -- Brian , , Don't _EVER_ lose your sense of humour....
