libpcap - seg fault

Postby ksu » 2017-03-10 20:25

Hello,

Any suggestions on how to attempt to start debugging this problem?
It has been like this since ifirst tried any lbpcap dependent application(...) System installed in Mar 2015... I was hoping to have it solved on every kernel upgrade for Jessie:

Code: Select all
$ nmap -sS 10.0.0.0/24 -e eth3

Realtek disabled - imo Intel is the way to go, for number of reasons.


Thanks!
