So again... Some of you guys need to go back and read before you post....

awk 'NF<=10&&($6=="nvalid"||$7=="user")&&$9=="from"{print $10}'

Once you try a moronic name insertion it makes the columns more than 10 
rows invalidating it.

discussed and resolved. Is there anything else? Perhaps I should 
re-write TCP into the script
to ensure no one ever spoofs again.
