Hello,
I am running Ntop RC2 built from current 6/29/2002 source on a Redhat 7.3
system (Pentium III 866 with 128M) and am getting a segmentation fault.
(I am monitoring three interfaces here but it faults even if I monitor one)
(I was getting the same error on RedHat 7.0 too)
Here is the configuration file and gdb trace.
let me know if more is needed. I am not on the list so please email me
seperately.
thanks
Earl
