It's really not that hard to run under gdb and see what line failed -- Instructions are at http://snapshot.ntop.org

They all seem to segfault regularly. I read the FAQ and hopefully I have all of the information any of you might need to debug this problem. I ran at trace level 1 for this. I will up it to level 2 and report the next segfault too, but it uses up quite a lot of disk space to go any higher. I tried reading hash.c ... but its extremely difficult to know where this null pointer might be coming from. :-/ Command Line:/usr/sbin/ntop -d -L -u ntop -w 3000 -p /etc/ntop/protocol.list -P /var/lib/ntop -S 1 -a /var/lib/ntop/access.log -i eth0,eth1,ipsec0 -t 1 -O /var/log/ntop/ -E -K I downloaded the source and Dennis's diff to debianize it from a debian mirror. I compiled it on a Debian 3.0 box, gcc 2.95.4 20011002 (Debian prerelease). Thanks very much for all of your work Burton. I wish I could help you more with ntop.
