RE: SSH to IBMi

Using the -t switch allows the password to be sent when connecting to the Linux system. Is there a reason that does not work on the IBMi systems?

Failing that, I guess the keys must be used. I've not been able to connect that way yet.

Thanks,
Todd

The server can't find a public key that would let you go in without a password so it wants to prompt you for a password. It can't open the tty for prompting you, so fails. You probably want to use keys for running this.

I have a Websphere Jython script that has been tested and works fine.
I can call it from PuTTY with no problems. (I had to replace the qsh
bash with sh to work outside of QShell.) Now I am trying to call the
script via SSH and it fails with the “permission denied” error. It
appears the SSH connection is working fine but I’m puzzled why it
fails after that. The verbose log is below. I don’t know if there is
a problem with the SSH command itself or the SSH server setup. Any guidance is appreciated.
