Hi there! Last week I suddenly got caught by the infamous LCP loop bug. It appeared all of a sudden; I hadn't done any changes, nor had the ISP at work. After figuring out that I had the same problem as some others have had, I applied the patch that Marc van Woerkom <van.woerkom@netcologne.de> posted to the list (subject: "Infinite loop (sppp/lcp)"). After that, I can connect alright, but it takes about ten seconds instead of the normal 1-2 seconds. Since I am about to install i4b on some ten boxes for colleagues at work, I'd thought it would be nice to kill this bug. I want BSD (I use NetBSD) to look as good as possible, and this ten second connect delay is then hard to explain. I use NetBSD-current (i386) and i4b-0.90. The ISDN card I'm using is the AVM Fritz! PCI card. Now to the problem. Below are transcripts from /var/log/messages (produced by the isp0 device after setting the debug flag), from isdntrace (on the same connection attempt), and from tcpdump* (from another connection attempt). *I have modified the print-ppp.c in the sppp directory to work with the NetBSD tcpdump. I can send patches if anyone is interested.
