Look for ports on specific IP?


Recommended Posts

this computer is say on subnet a ...

Is there any way to scan for open ports on an IP on subnet b? (windows machine)

eg. currently having 192.22.33.11 ... (i can display the listening ports) ... is there any way to display the listening ports for 192.21.51.33?

So you want to know what a remote machine is listening on?

nmap is a simple tool you can use. So for example quick scan

nmap -T4 -F 192.168.1.7

Starting Nmap 6.01 ( http://nmap.org ) at 2012-07-20 23:29 Central Daylight Time
Nmap scan report for ubuntu.local.lan (192.168.1.7)
Host is up (0.0013s latency).

Not shown: 95 closed ports

PORT      STATE SERVICE
22/tcp    open  ssh
53/tcp    open  domain
80/tcp    open  http
443/tcp   open  https
10000/tcp open  snet-sensor-mgmt

MAC Address: 00:0C:29:97:69:07 (VMware)
Nmap done: 1 IP address (1 host up) scanned in 0.31 seconds
