ax0n Posted December 8, 2008 Share Posted December 8, 2008 Ostensibly, most open ports are services, so you should connect to the remote PC's open ports with the client that utilizes them. Port 21 is usually FTP. 22 is usually SSH. 80 is usually HTTP (web server) and so on and so forth. THIS may help you out. You can try to use a command line tool to see if the port responds. I usually choose netcat (nc.exe on windows, nc on Linux/BSD/OS X). In the case of both telnet and netcat, just use the following syntax: telnet (or nc) hostname port Here, I'll use nc to connect to the SSH port on my DMZ box: chimaera:~ axon$ nc bouncer.labs.h-i-r.net 22 SSH-2.0-OpenSSH_5.1 Protocol mismatch. Telnet is not only "noisier" (displaying a lot of extra stuff to you) but it doesn't always generate a clean TCP session that contains ONLY what you type. It tries to perform a telnet handshake, which can throw some results off. Regardless, this is the same thing done with telnet. chimaera:~ axon$ telnet bouncer.labs.h-i-r.net 22 Trying 192.168.0.10... Connected to bouncer.labs.h-i-r.net. Escape character is '^]'. SSH-2.0-OpenSSH_5.1 Protocol mismatch. Connection closed by foreign host. Hope this helps.

aeturnus Posted December 9, 2008 Share Posted December 9, 2008 I want to know can we connect remote pc's open port. What are the different ways . . and what is the command used in telnet to conect. Besides the tools listed above, using a simple Python script (or any language that supports sockets), you can just create a socket and have it connect to the port on the remote machine.

I think you're asking for how to transfer files using Telnet. It's my understanding that it depends on the version of Telnet you're using. If it's simply text, just cat the file. If there's a lot of files, it'd probably be easier to just install FTP on the remote system or something. Quote Link to comment Share on other sites More sharing options...
remezcle Posted December 15, 2008 Share Posted December 15, 2008 Um.. yes you can connect to a remote ip... you do it every time you go to google.com? Quote Link to comment Share on other sites More sharing options...
c0der3d Posted December 16, 2008 Share Posted December 16, 2008 Depending what port you connect to, you will have to specify the appropriate commands. For example, if you connect to port 80 of a web server you would type the following: cmd > telnet www.google.com 80 cmd > GET / press return, you will get the whole index page of Google. I recommend you use Netcat as it works better. The same is valid for other ports, just know what protocol you are using. Good Luck! Quote Link to comment Share on other sites More sharing options...

Sparda Posted December 26, 2008 Share Posted December 26, 2008 If a port is open a service is listening. Telnet will connect you to any open port and allow you to interact with that service. Quote Link to comment Share on other sites More sharing options...

That was supposed to in reply to the earlier post. I was thinking in a more narrow spectrum, as in remoting in to another computer. And in my opinion, SSH is a perfect utility for that.
