SSH connectivity with username & password returns empty response

[jsatishkumar]

Receiving empty response when I try to collect metrics using ssh with username and password. Any idea ?

maybe wrong params like ip username password or shell script run failed. you can debug to find why.

I have tested using terminal and it works. But when I use hertz, I get empty response. I have hard coded the command in ExecChannel instead of passing script, this is also returning an empty response.

I can't reproduce the issue. i am doing some work about ssh monitor , could you provide more detailed reproduction steps?

Hi Masami,
You need to have a old version of SSH library in order to generate this bug. I am using a device with very old version of ssh library

the very old version ssh library, have you considered that the ssh algorithm does not support. Maybe need debug with sshd.

Yes, May be the ssh algorithm is an issue. The outputstream is always empty in sshd in the channel.
