Description onox 2010-11-25 18:29:00 UTC
I'm using 0.3-beta6 (-r3 in gentoo) and when I do netdiscover -i eth0 -r

so without the / (and without a number behind the /) it seems to segfault.

dmesg output:

device eth0 entered promiscuous mode
netdiscover[23628]: segfault at 0 ip 51acd04b sp 5029829c error 4 in[51a9e000+145000]
grsec: Segmentation fault occurred at (nil) in /usr/sbin/netdiscover[netdiscover:23628] uid/euid:0/0 gid/egid:0/0, parent /bin/zsh[zsh:23597] uid/euid:0/0 gid/egid:0/0
device eth0 left promiscuous mode

Reproducible: Always

Steps to Reproduce:
1. Start netdiscover with -r <ip> instead of -r <ip>/<number>

Actual Results:  

Expected Results:  
Error message saying format of -r is incorrect.
