Argus SrcID And SrcID filtering

Hey CS Lee,
You need to escape the double quotes, so that they make it into the compiler:

   ra -S URI://127.0.0.1:561 -s srcid saddr sport dir daddr dport - srcid \"eth0\"

without the quotes, ra will think you are looking for the IP address of the host 'eth0',
which probably is not in your namespace.

So without making a bit of a change in the srcid DSR definition, you only get 4 bytes
for the srcid.  This can change in 3.0.8, but right now you're limited to only
4 chars (32-bits).
