Hi all,
I'm writing you to submit a ntop segmentation fault.
The system I used was a Slackware with kernel 2.2.21.
A gdb output follows: the ntop version I compiled is
the ntop-current of July the 2th.
The crash, on the same system, also occurred with
the stable version of ntop.
Here's the gdb otuput:
/usr/local/bin/ntop -q -c -i eth0 -W 0 -S 1 -u nobody -d
