how do i telnet. i get the answer as "connection refused' every time?

Question

i am using a proxy server to connect to internet on other computer in LAN. i try to telnet the other computer and sont get the connection. Can anyone also explain me th etelnet and port number in detail? or direct me to some arcticle??

Answer 1

The fact that you get "connection refused" means you're reaching the other computer, but most likely, there is no 'telnet daemon' listening for an incoming connection. It's become rather unfashionable to use 'telnet', as the userid and password are sent across the network in readable form, where any packet sniffer can read them. As a result, most Unix and LInux machines use a program called 'ssh' instead - youre far more likely to find an ssh listening on port 22 than to find a telnet listening on port 23 (the standard telnet port).

To find out if anything is listening on port 23, you want the 'netstat -a'n' command - if nothing is listening on port 23, you can't telnet in. How to start a telnet listener is operating system specific.

Answer 2

Proxy servers generally are for web pages or HTTP service (port 80).

A connection to a Telnet service is made to port 23, and it has nothing to do with a proxy server. If you are on a a subnet and you get response to a ping command from the server wich you want to connect to, it's pretty sure you can telnet to it. If the ping doesn't respond, it means you don't have connection to the target host.

Commands:
c:\>ping other_host_ip(and press enter)
This test if you have connectivity to the other host
If you get something like "Response from..."
then you can try a telnet connection:
c:\>telnet other_host_ip

By the way, when you connect to a host's telnet port, must of the time this host it's a unix/linux host. Telneting to a windows host, it's pretty weird...

Answer 3

Telnet works on the default port of 23. It is not a secured way of communicating between the client and the server, so most of the organizations use the SSH protocol instead of telnet.

Refer to this RFC to get more information about the telnet protocol. http://www.faqs.org/rfcs/rfc854.html
