I'm unable to reproduce it with 2.05: sudo ./arping -q -c 1 -T $a.$b.$c.$d $TARGET_MAC arping: Can't resolve ..., or ... is broadcast. If it is, use -B instead of -T
Obviously without the env stuff set this is the same as "arping -q -c 1 -T ...", and only "arping -T ..." is needed to segv 2.01. Since the parameter to -T is sent verbatim to libnet, the segv itself looks like it's in there. It looks like I didn't init libnet in 2.01 (mea culpa), however this is fixed in 2.05 (or possibly sooner. It's been a while), and I can't reproduce it with 2.05. Are you SURE it's still in 2.05? / Thomas Habets - the author of arping
