Enabling Logging for SSH2 Library

If the SSH2 connection fails with no useful information in the PPM logs, you can route the logs of the JSch library to a dedicated file and set its logging level to a more verbose setting by adding the following text in your logging.conf file. You can change the red parts as you demand.

# SSH2/JSch logging. 
log4j.logger.com.kintana.core.net.ssh2.jsch=DEBUG, JSCH_LOG 

# JSCH_LOG has a dedicated log file to easily pinpoint any error during SSH2 connection.

log4j.appender.JSCH_LOG.Append=true
