This program is a tcp port scanner. I wrote this because all the other port scanners I downloaded for the mac didn't work very well.
This program can also scan multiple hosts for a single port.
(For example: Scan for port 21 on hosts: 123.456.789.0 to 123.456.789.255)
It can scan a host for commonly used ports as well.
Double click a accepted connection to see it's protocol.
The short list of recognized protocols are:
7/echo
9/discard
11/systat
13/daytime
15/netstat
19/chargen
21/ftp
23/telnet
25/smtp (mail)
69/tftp
70/gopher
79/finger
80/web
88/kerberos
109/pop2
110/pop3
139/netbios-ssn
143/imap
194/irc
220/imap3
540/uucp
548/Apple-Share IP
1080/WinGate
6667/irc
5500/Hotline Server
5498/Hotline Tracker
8080/web
31337/Possibly Back Orifice

Cahnges in v3.3b
• Added 'multi-host single port scan' option (timer support with this option)
• Added 'scan common ports' option
• I chose not to add timer support for regular/common port scans, error checking for those
is not really necessary, if someone is stupid enough to try to scan a host that is down it
will just sit there. (sooner or later they will get the idea it errored out)

Updates from v3b:
• Save output menu added
• Minor fixes
One more note, this program makes a full socket connection to the host you are scanning, so if the host has good logging your ip/hostname will appear all over the logs.
