With win XP's arrival.. The ability to spoof of the source address is
apparently very easy accomplished http://grc.com/dos/xplaughter.htm.
In fact I am wandering why MS did not include a GUI to make this
I am curious as to how people are verifying there sources and what ISP's
are doing to verify them as well..
if [ -e /proc/sys/net/ipv4/conf/all/rp_filter ]; then
for f in /proc/sys/net/ipv4/conf/*/rp_filter; do
echo 1 > $f
Do some of the most common DSL/Cable routers with built in fire walls
protect against this??
Also are there any free legit tools out there to test for this both on
the ISP's side and test personal firewalls???
