using nmap to scan for a specific server on the network..

I've been trying to use nmap to scan for specific server on the network like MSSQL which by default runs on port 1433, now I've used nmap like this
"nmap -sP -p T:1433 192.168.10.*" now this would actually scan the network looking for a computer with the service running on port 1433, and report it back as open, the only problem with this scan is that it reports every node alive on the network only that reports it as port status closed...my question is; how could I run nmap that only reports the machine running service on port 1433 and not every machine up on the network?...this applies for any other service, like http, telnet, ftp, etc..

thanks in advance...

Add -P0 (P null) to not ping hosts and/or --open to only show open ports.

Man nmap for more info...

NB IIRC that -P0 got changed recently.. Look in the manpage..

Careful playing with that nmap. Back in my noobest of noob days I tried toying with it and inadvertently brought the whole company network down. Yep, nothing like DDOSing yourself.

Good times, those were, good times.

Is that one of the apps that some of the European countries have outlawed? Seemed like I had heard a year or two ago that was the case.

That would be Germany.. They've got some backward anti-hacking laws :drink:

Nmap is considered a hacking tool :rolleyes:
As such having a tool like that in your possession makes you a crimi^H^H^H^H^Hterrorist..

the UK is heading in the same direction....

SirDice, I tried your method and still didn't work, it will report every host on the net... I remember a while back using nmap in a way that it will only scan the net for a specific service....

Try "nmap -p 1433 192.168.10.0/24" for that specific port.

Should work.
