For Newbie: what is a port on a computer? A computer port is sort of like a seaport. It's where things can go in and/or out of a computer.
Telnet is a remote logging command so it is use for log into a remote computer.
Every day people complaining they can't telnet. That is usually because they try to telnet into a computer, or a port on a computer that is set up to refuse telnet connections. Here's what it might look like when a computer refuses a telnet connection:
C:\hrde >telnet 10.0.0.3
Connecting To 10.0.0.3...Could not open connection to the host, on port 23. A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
Or you also see:
C:\hrde >telnet techbroker.com
Connecting To techbroker.com...Could not open connection to the host, on port 23.
No connection could be made because the target machine actively
refused it.
If you just give the telnet command without giving a port number, it
will automatically try to connect on port 23, which sometimes runs a
telnet server.
So firstly found the IP address of the Victim and use ‘Port Tracer’ tool for trace the open Port on victim System.Many tool are available on internet you got it by search on Google Uncle.
After that run according to shown below…
C:\hrde>telnet ip-address port-number
And press ENTER key.
If telnet failed to connect, possibly the computer you were trying to
telnet into was down or just plain no longer in existence. Maybe the
people who run that computer don't want you to telnet into it.
