Failed: SSHProtocolFailure: failed to send channel request

[Samuel Neves]

Hello Guys I have a project with the "Pass RD_*" flag enabled, but one specific job does not need this env vars, and when I try to execute this on this remote node I am receiving the following error: 

```H_MSG_KEX_ECDH_INIT sent

expecting SSH_MSG_KEX_ECDH_REPLY

ssh_rsa_verify: signature true

Permanently added 'REMOTEHOST' (RSA) to the list of known hosts.

SSH_MSG_NEWKEYS sent

SSH_MSG_NEWKEYS received

SSH_MSG_SERVICE_REQUEST sent

SSH_MSG_SERVICE_ACCEPT received

Authentications that can continue: publickey,password,keyboard-interactive

Next authentication method: publickey

Authentication succeeded (publickey).

Disconnecting from REMOTEHOST port 22

SSH command execution error: SSHProtocolFailure: failed to send channel request

Failed: SSHProtocolFailure: failed to send channel request

Caught an exception, leaving main loop due to Socket closed

[workflow] finishExecuteNodeStep(REMOTEHOST): NodeDispatch: SSHProtocolFailure: failed to send channel request```

When I disable the "Pass RD_*" the job works properly. Anyone knows if there is a way to keep this flag enabled at the project level and run this job on a remote node without this error? And why this error is happening?

Hi Samuel, which Rundeck version are you using? Could you test with the latest one? It seems related to sftp (file copier).

Also, a good test could be using the SSHJ/OpenSSH node executors instead of the default SSH.

Regards.

I will take a look soon at your suggestion.
