sshj and sudo with password authentication is not working

[watzsch]

Describe the bug
I want to migrate my Linux project from jsch-ssh to sshj-ssh. When I am activating sshj-ssh, no sudo commands with password authentication are working.

My Rundeck detail

• Rundeck version: 5.1.0
• install type: deb
• OS Name/version: Debian 11 (bullseye)
• DB Type/version: postgres
• sshj-plugin version: 0.1.10

To Reproduce
Steps to reproduce the behavior:

1. get a Debian Node up and running (in my case Debian 12)
2. add on the node in /etc/ssh/sshd_config the line PubkeyAcceptedAlgorithms +ssh-rsa to make jsch-ssh working...
3. configure the node only to allow sudo with password
4. test it with jsch-ssh, for example running a simple command, the result should look like:

7. add to the node definition parameters to use sshj-ssh:

9. run the same command in rundeck again... now the result shows an error:

Expected behavior
the sudo authentication and command execution works as with the jsch-ssh plugin.

Hi @watzsch

It seems related to this one.

Hi @MegaDrive68k

I have the same issue than @watzsch.
According to the link you shared, it seems that new default library sshj-ssh is not compatible with sudo commands yet so we still need to use old jsch-ssh.
