Hello Ludovico and Damien, I experience this same problem. I am also
running ntop 3:4.1.0+dfsg1-1 and I confirm that /etc/default/ntop contains:
> GETOPT="-n 0"
- so DNS resolution is disabled
I started ntop inside gdb, as you describe. I paste below the output of
"thread apply all bt". Can I provide any more information?
administrator@debian:~$ sudo gdb --args /usr/sbin/ntop -u ntop -P
