Meaning of different timeouts in SSHJ

Question

I am trying to use SSHJ to connect to a SFTP from my Java application. There are a couple of different timeouts that are present but I can't find the difference between them. Even the official docs aren't very helpful. Can someone explain the difference between?

SSHClient.setTimeout()
SSHClient.setConnectTimeout()
SFTPEngine.setTimeoutMs()

Thanks in advance.

Answer 1

• SSHClient.setTimeout() – It is propagated to Socket.setSoTimeout – See What is the functionality of setSoTimeout and how it works?

• SSHClient.setConnectTimeout() – It is propagated to Socket.connect – See How to set timeout on client socket connection?
• SFTPEngine.setTimeoutMs() – How long to wait for a response from the SFTP server. Basically, it seems to be an equivalent of SSHClient.setTimeout(), just on a different OSI level.
