Hi,

I figured out that when I try to enter the password for telnet login manually, it is accepted.

However, it gives "Password Incorrect" message when I try to do the same through Java. I have a Linux machine for development environment.

Does this mean that the telnet expects the password to be entered only by waiting on keystrokes ? If yes, is there some way in which we can change these settings ?

Heiner Westphal,

My password is c1sc0fR33. I don't think any of these characters are outside the ASCII range. I have just appended the password field with a 'newline' character.

Pan Li,

The PortForwardingL.java might be for the same user (who has logged using SSH) to share the port and session across a telnet session ? What I want to do is to connect to a remote machine using SSH credentials. Now that I am connected, I would like to telnet to some other remote machine with the different credentials using the same JSch library calls.

Do let me know your views on the same.

Regards,

Prasad Shindikar

I guess your server uses a character encoding different from your client's. This invalidates your password, if you use characters outside
the range of ASCII.

Try "echo $LANG" on your server, if it is a u*ix box.
Current versions of linuces use UTF-8 while Windows sticks
to cp1250 (?) - at least my Win XP does.

You can try to start your client with
 java -Dfile.encoding=UTF-8
and see if it makes any difference.

I am not sure I understand you question correctly.
If you mean you want to run shell command on remote server, then you should find Shell.java to see how it works

If you mean you want to use a telnet client over an SSH connection, see PortForwardingL.java

[JSch-users] Can we telnet on top of SSH connectivity through JSch ?

------------------------------------------------------------------------



Hi JSch Users,

I would like to telnet to another machine, after SSHing using JSch to a gateway.

Is telnet supported on top of SSH functionality?

I am getting an error while trying to enter the password. Although the password is correct, I get back a response saying "Password Incorrect".

Any help in this regard is appreciated.

Regards,
