Portscan?

[michaelsanford]

Is there a linux utility to port scan (terminal only)? I can't find one that's intuitively titled (liike portscan, pscan, etc).

I know Network Utility does it but I'd like a terminal one if at all possible.

Thanks!

try nmap, either through fink, or compile it yourself (works without a problem):

Cool thanks!

Try SNORT over at SourceForge.

Incorrect. SNORT is an Intrusion Detection System (IDS) and a good one at that; it can behave as a packet sniffer, packet logger, or full network IDS, but it is *not* a port scanner.

Nmap is indeed a port scanner. It does what michaelsanford is asking for. If you want additional functionality, maybe you can get Nessus, the full-blown vulnerability assessment utility to run on top of nmap.

Nmap is one of the best port scanners i've seen. It can go through firewalls. And it packed with tons of options.
