The SSH Build Agents plugin make an sftp or scp (if one fail try the other) with the user configured in the Jenkins Agent to copy a file in the "Remote root directory" folder configured in the Agent config, nothing special, if the user configured in the Agent can make scp/sftp to copy a file in that folder it should not fail.
The point where the Agent fails to copy the file is interesting, it checks the value of the read bytes and fails if is <0 or >32768, I will bet the value is `-1` and it is related to read the remoting.jar from the Agent to check the md5, for some reason is returning an EOF https://github.com/jenkinsci/trilead-ssh2/blob/master/src/com/trilead/ssh2/SFTPv3Client.java#L1231 https://github.com/jenkinsci/ssh-slaves-plugin/blob/main/src/main/java/hudson/plugins/sshslaves/SSHLauncher.java#L706 El viernes, 18 de marzo de 2022 a las 16:10:56 UTC+1, eric....@gmail.com escribió: > Hmmm, I deleted the remoting.jar file and was able to restart Jenkins and > the node came up.
