Check out http://www.FreeBSD.org/FAQ/userppp.html for some hints on how to generate some useful information. Also, be careful. It's likely that the ``Interrupted system call'' is an error resulting from a decreased ``redial'' timeout forcing ppp to attempt to re-open the port too quickly after failure and blocking for more than 1/10th of a second. It is very unlikely that this has anything to do with the actual problem... the log files should reveal this. -- Brian , , Don't _EVER_ lose your sense of humour....

I haven't included it since it contains passwords etc, but I've cc'd this to freebsd-gnats for tracking purposes. It seems that your ISDN link is synchronous - ie, the ``async'' layer that data passes through at the link level is not required. This is evident by comparing the data you're receiving at the async level (async logging) with the data that's being sent at the hdlc level (which is then escaped etc. at the async level). Ppp can support this in theory, but in practice it's horribly broken and I don't have the (hardware) resources to even attempt to fix it. However, all's not lost. Joerg has done some work on synchronous ppp, but you'll need to use the kernel ppp implementation. The sppp(4) man page describes how to go about getting things up and running. I'm afraid I know very little about kernel ppp, so if you run into difficulties, your best bet is to ask some questions on freebsd-questions@FreeBSD.org Sorry I'm not more help. Cheers. -- Brian , , Don't _EVER_ lose your sense of humour....
