I'm looking for a portscanner that scans a range of ip's and tells the status of a port.. so this means, also when there is nothing running on that port!

IP1 - Refused
IP2 - Timed-out
IP3 - Can't resolve hostname
IP4 - Listening! Banner: 220 Serv-U FTP..
IP5 - .......
...............................

ect..


is there such scanner like this?

yea that would be cool..something like

Scan -host IP-IP -p PORT-PORT

then it can reply if the ports ARE Open\Stealthed\ or Closed.....

One obvious solution is to create a port scanner. You can find simple tutorials online on how to make one in Visual Basic. However, I think the tool that might interest you would be Angry IP Scanner available at: www.angryziber.com/ipscan
I've used it before, and LOVE it. Small and reliable, and good.
Anyways, just my suggestion. Hope it helps, if that's not it, maybe you can get someone here to code one for you. You just want it to scan an IP Range and tell what services the port it running right?

greetz

u mite be able to make it urself in abatch..... use mkque.exe (do a search) and that will create a list of ips for you to scan against.

2nd step would be to get a proggie (maybe slscanner) am not sure aboutr this 2nd part wat other porggies to use to test each of those ip's againt a port u specify.

ill have a look into it, meantime if anybody knnows what scanner can scan a list of ips (scan.txt) for manually enetred ports (not scan500.exe), but it has to be command line.

worth thinking about.

3rd step would be to be like to scan for the banners on each of the ip's that had the specified port open and grab them

The program you seek already exists and is open source. It's called nmap. It is available at http://www.insecure.org/.

xscan can also good portscanning

i cannot get nmap working, ive tried over 7 different syntaxes but i always get this:

# nmap 3.50 scan initiated Wed Mar 31 18:55:28 2004 as: nmap -v -O -p 21 -oG 9.l sP 131.155.0.0 131.156.0.0
# Ports scanned: TCP(1;21) UDP(1;21) PROTOCOLS(1;21)
Host: 131.155.0.0 () Ports: 21/filtered/tcp//ftp///
Host: 131.156.0.0 () Status: Down
# Nmap run completed at Wed Mar 31 18:55:51 2004 -- 2 IP addresses (1 host up) scanned in 22.344 seconds

try sl scan by foundstone its a banner scan and other

Seems the commands you should be using for the nmap scan should be

nmap -v -O -p 21 -oG 9.l sP 131.155.0.0-131.156.254.254

to cover the full range.

The ScanLine tool from foundstone (www.foundstone.com) is also an excellent choice and supports banner display well.

Invalid caracter in host specification.
QUITTING!

If you have admin rights to the box that you are scanning from, I'd advise looking into and getting Retina's Iris or GFI's LANGuard Security Scanner. Retina is a trial and you can get LANGuard for free for non-commercial uses.

Outside of this, I'd recommend Nmap.

ip-tools dose exactly what your looking for and is one hell of a tool, i recomend looking at this.

chars then.

Your right Alexander01. That doesn't work. It should be

nmap -v -O -p 21 -oG 9.l 131.155-156.1-254.1-254

remember to use -sP not just sP. Also, you cannot use the -sP option with -O, as OS detection won't work with -sP.

Nmapwin is simpler to use
