Hi,

I ran the nmap command for ~11 minutes and the output file is ...

[scanner_at_clouseau ~]$ ls -lt | head
total 2231076
-rw-rw-r-- 1 scanner scanner 2207219285 Dec 15 21:52 namp_test.out

Wow, that's big. Looks like a loop that never ends. Here is the
first minute ...

There is no firewall at the Fermilab border, so you can run the
command if you wish.

Thanks for your help.
Randy Reitz
