According to SolarWinds, who support Serv-U, this is caused by the fact that the Jsch library does not strictly adhere to the SFTP RFC. See https://support.solarwinds.com/SuccessCenter/s/article/Unable-to-connect-through-SFTP-using-Java-based-clients-after-upgrading-to-Serv-U-version-15-3-2?language=en_US

They have provided a patch for Serv-U that can fix this issue, but they recommend that users of Jsch update it to a version that fixes this RFC compliance issue. The original Jsch project seems to have been abandoned, but this fork resolves the issue and is backwards-compatible: https://github.com/mwiede/jsch

Just wanted to file this in case it helps others.

What Operating System are you using (both controller, and any agents involved in the problem)?

Windows Server 2012 R2

Reproduction steps

  1. Try to publish SSH artifact to Serv-U server version 15.3.2.172 or newer, or configure such a server and click the 'Test Configuration' button.

Expected Results

Successful connection and publish of artifact.

Actual Results

Connection fails with stack trace shown above.

Anything else?
