Hello all, I'm running ntop 4.10 (32 Bit version) or 5.0 (always 32 bit version) and they just crashes when the binary start with segfaults either daemon mode or not. I'm running on VM Slackware Current on physical server with CPU I7 and 24GB mem. Into dmesg file i found this :
dmesg | grep ntop [1232095.316759] ntop[12004]: segfault at 0 ip b7438f1f sp bfe810b0 error 4 in libc-2.15.so[b739a000+17a000] [1232452.483032] ntop[12184]: segfault at 0 ip b73e6f1f sp bfbf53b0 error 4 in libc-2.15.so[b7348000+17a000] [1232456.918648] ntop[12185]: segfault at 0 ip b7356f1f sp bfd194b0 error 4 in libc-2.15.so[b72b8000+17a000] [1232468.630957] ntop[12192]: segfault at 0 ip b73faf1f sp bffad590 error 4 in libc-2.15.so[b735c000+17a000] [1232480.051064] ntop[12196]: segfault at 0 ip b73a9f1f sp bff9b9c0 error 4 in libc-2.15.so[b730b000+17a000] FYI here is my kernel and glibc version: uname -a Linux monitoring 3.2.23 #2 Thu Jul 12 22:32:00 CDT 2012 i686 Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux ldd --version ldd (GNU libc) 2.15 Copyright (C) 2012 Free Software Foundation, Inc.

Until a few months ago the same VM with NTOP 4.10 worked without any problems, probably after some updates (kernel, Glibc) has stopped working but I can not find where is the problem. >From gdb debug i found : gdb /usr/bin/ntop GNU gdb (GDB) 7.4.1 Copyright (C) 2012 Free Software Foundation, Inc.
