I need a tool i can run in cmd.exe that will show open ports by a router. A tool that would show the ports that the router has open.. Does anyone know of any.

log viewer,link logger, wall watcher,ect...

those are gui and logs viewers i need one that just show the ports open by the router

isaiah use nmap for dos

use a port scan
I use portscan.exe and it work
but i think u whant a tool for runing on the victime, exact ?
a tool same as will be more quickly but i dont no a tool like that
PS : sry i'm french

a port scanner is the most usefull to do this
nmap is very good to do this job

What's the problem with just scanning yourself with a simple port scanner
and see what ports are open?

If you want to see the ports that are allowed to be opened by the router,
It's all in the configurations, unless your on a DMZ stat,
which say's: "If something wants to connect... he connects!"

P.S.
Most router open port 23 for remote connection to them,
and port 80, for a comftarble Web Interface Configurations.

Port 80 is the HTTP protocol Port,
IIS (Internet Information Server) is a HTTP Server...
There are a lot more HTTP servers and all of them has nothing to do with the current subject we're discussing.

and also port 3389 (Which is the Remote Desktop Protocol (RDP)) is not related to this topic.
but...
You can try closing it... if it allows you, it's Ok... if it doesn't, it doesn't...
Simple as that.

i know there was a cmd for netcat you can give the remoteip and the start and end port! it shows you which ports are timedout opened and refused! the one that are refused you can use for your service but i dont find that f****** cmd

I heard ports 80 and 443 are always oben

Netcat is very useful for a CMD based port scan in my opinion.

depends if you want internal or external, guessing external... in which case port scanner will work just like it would as if it was a normal computer... internal, same way, but scanning your external IP will show you exactly what attackers see

as everybody said... scan yourself... or check netstat with -ao for extra info.

and dear CereBrums i must correct your saying:

"If something wants to connect... he connects!"

DMZ stands for Demilitarized Zone...
it does not mean it lets anybody connect to it when it asks...
it puts your connection in a special zone where you stand between the internal network and the external, the internet, this puts you almost open for every connection but it is still passes thorugh a firewall for basic level network filtering, which allows you to get a more loose connection , thus you get the feeling of anything can connect whenever they want...DMZ also creates a basic sepration between the two networks... if u r an http/ftp server that recives connection from external users DMZ will seperate the connection/data from the internal one thus providing another level of security...

when i wanted to check wether my port forwarding works, i telnetted the routers internet ip to the specified port and he couldnt connect, but from PCs outside the lan he could.i think its related to the routing of the router. i cant check my routing table cause cant access the router atm.

so:scanning yourself through the router may be misdirecting

so long
