Subject Re: sshexec Authentication Problem with SuSE 9.1
Date Wed, 08 Dec 2004 14:11:50 GMT
Hello Rob,

the error output is at the end of the message. The way I read it
JSCH is not supported by sshd.

The debug information from sshexec task is the same.

Atsuhiko suggested to enable  "PAMAuthenticationViaKbdInt" which is 
decaprecated
in OpenSSH.3.8. 

Regards,

Peter
