Detecting interfaces on a router through remote login

[jackandjill]

Hi

I can connect to a router which is used for IP forwarding.
I want to know how to recognise the number of interfaces on the router.
What hosts or routers are connected to that router?

Is there anyway to do it?

Thanks in advance for your valuable time.

Try logging in to the device with the admin password...

That should show you

What type of router is it, CISCO etc?

[d0pp]

nmap -T2 -O -P0 -sV -v -v <router's IP>

This will generally identify any machine you scan, as well as give you service/daemon versions. When you scan the router... Lets say it's a Linksys WRT54G... check the Linksys website. You should get a bit of information on it.

NMAP is required for this. Unix/Linux/BSD helps due to the manner in which hardware access is handled, but Windows nmap can scan just fine for your purpose.

HI
thanks for the fast replies.

I am using nmap through ethernet,so OS and Version detection gives an error on my Windows 2000 Proff system.Although i have admin access it gives some socket errors.

Can you tell me some other program for OS and Version detection.
Thanks in advance.

Ping can be used to guess a footprint, look it up

Hi

I found some information after tweaking with nmap.

It is like this:
PORT STATE SERVICE VERSION
22/tcp open ssh (protocol 1.5)
23/tcp open telnet Netscreen ScreenOS telnetd
80/tcp open http?
443/tcp open https?

Service Info: Device: firewall

If you could suggest something?
