Can you please provide more detail i.e. what is the context what you tried etc...
Both issue are different. I was trying to connect to a remote machine by JSch. But "session.connect()" was throwing exception.

I solved this issue by flushing iPTables(iptables -F). Works for me!!
Trying to figure out Why.

This exception occurs whenever jsch.Session.connect fails, most common reason is password is wrong and others could be the obviously connectivity issue.

IPfilters blocks the traffic to the machine based on the settings and flush will clear them all so :)
can you elaborate how do we do that ? flushing table
