You can find out every service there is running and see if there is an exploit for it. This is not only good for hacking, it is very good for trying to make a server as secure as possible. Also, some port scanners let you search an entire class B or C network for a service, such as FTP. There are several port scanners available, some are even shareware. There are plenty of good free ones available so I suggest not buying or cracking any shareware ones. I have tried several, most are about the same in speed and options. Win 95/98/NT Portscanners Every program here I tried myself, that was how I got my descriptions. PortScan Plus (1.7mb) - Pretty good and simple. Lets you scan all ips you want and a set of ports in a range. Such as 1-80, which would be better if you got to select each port you wanted to scan though. Also you can set how many threads you want to use. For just a portscanner this one is great. [- Get it -] wGateScan 2.2 (34k) - Designed for finding wingates, this tool is very useful for all sorts of things. You can scan up to a class B network for any service. You can also test the service in some ways to see you can use it or scan for a version of a service by using the try to receive string option. I think this tool is a must for searching for servers running a particular service. [- Get it -] YAPS (Yet Another Port Scanner) 1.2 (1.2mb) - ShareWare. Very fucking good scanner. I like the feature of how it tests anonymous login on FTP servers. There is a Key Gen for this available cr-yap11.zip, but I will not provided it due to legal reasons. This would be very usefully for finding servers to store warez, mp3, etc. If you set the max threads and ports up higher it is fast as hell too. Scans up to 4096 ips at once. [- Get it -] 7th Sphere PortScan v1.1 (10k) - Pretty good if you just want to scan a single host. Also very small. Ogre v0.9b (1.4mb) - Lets you scan up to a class C for certain services. Bad thing is that it does not let you add services to the list. Port Scanner v1.1 (247k) - 30 day demo. This is a pretty good scanner. Lets you scan as many IPs as you want and any ports you want. UltraScan v1.2 (1.1mb) - About the same as PortScan Plus but it is Nagware. SiteScan by Rhino9/Intercore (16.1k) - You need HTML.OCX to run this program, I could not find a copy. TCP Port Scanner (57k) - You need dssock32.ocx to run this. I could not find a copy. All Around Internet (2.3mb) - Not a portscanner. This is more of a little utility that lets you connect to a server on any port and talk to it. Could be very useful in testing the security of a service. Other things Common Port Lists - List of most of the common services there is. (a /etc/services file with a few additions)
