Complete!
[root@localhost]#

So I launch it
# urlsnarf
urlsnarf: listening on wlp2s0 [tcp port 80 or port 8080 or port 3128]

All is well until I go to Firefox 41 and enter any url, then urlsnarf panics and ends.

urlsnarf: symbol lookup error: /lib/libnids.so.1.24: undefined symbol: ip_fast_csum
[root@localhost]#
