telnet & socket prog..

[sridhar8310]

I tried to telnet my system i.e, 127.0.0.1 both in linux as well as windows but all I get is 'connection refused'. why is this so?
Also I created a srever program that binds itself over a port so as to respond to users connecting on that port in my linux box. But when I use $netcat 127.0.0.1 , I get 'connection refued' again here . Why do u think this is happ... .

is ur telnet port up and running?
i mean check ur ip with a port scanner to see if port 21, 23 open?

how do I do that, I don't have any port scanners. and if the port is closed, how do I open it.....

Are you sure there is no firewall running on your pc ......

LOL some weird replies in here.
First of all all the ports are open by default unless you purposefully close them by using some sort of a firewall on a windows machine.
EDIT:

i mean check ur ip with a port scanner to see if port 21, 23 open?

Duder port 21 is the default port for FTP[File Transfer Protocol].
From what I get from the post you are trying to connect to as in a client/server model?
Assign a IP address to the machine & specify a port say for a web server port 80 which is the default port.
Try accessing the same from a different machine by specifying the IP address & the port specified.
This should work if thats what you are looking for.
