HowTo: NAC / Network Authentication / 802.1x


Recommended Posts

If you have Network Authentication in place and the squirrel doesn't forward EAPOL Frames

In the tcpdump Payload:

1) Modify the transparent script and put the following line:

echo 8 >  /sys/class/net/br-lan/bridge/group_fwd_mask 
# Set networking to TRANSPARENT mode and wait five seconds

sleep 5

2) Set your squirrel to TRANSPARENT mode


Since Linux 3.2 the default linux bridge can forward EAPOL frames, but it does not on default because that's how a bridge is defined in the standard.
