[NTLUG:Discuss] Scanning networks

[bryn konti]

I should point out that since grc and dslreports are
really geared towards windows users they will NOT
necessarily give you a good scan....it may say all of
your ports are closed when they are not. Until you
install nmap on your linux box ( trust me, there's no
good reason for not having nmap to perform security
auditing) use this site to perform online nmap scans
of your linux, mac and windows boxes:

Cheers,

Bryn
