[JSch-users] Dropped Connections using JSCH

[M***@carolina.com]

We are using JSCH in an application compiled with Oracle JDK 1.6

We obtain, occasionally, a connection refused exception.

Are there any known issues with JSCH regarding dropped connections?

If so, is there a best-practice for the tool that will avoid this problem?

Thank you.

Dear Mark,

as far as my experience goes, JSch is pretty stable when it comes to connection stability. A "Connection refused" message occurrs more likely due to connection-configuration issues. In your case, I would aim at ruling out connection-configuration-based causes, like maxmimum number of sessions/connections/concurrent logins (have a look at your server configuration) or a simple timeout issue, first.

If you continue to get "Connection refused" messages, please provide more information to help us pin down the likely cause(s).

Greetings
Volker

I guess that exception has been thrown from
new java.net.Socket(host, 22);
That is a problem of the remote sshd server, not a problem in JSch, IMHO.
