We use a very simple SFTP script to transmit files to various external vendors.
With one specific vendor, the process hangs when trying to connect to the host:
Session session=jsch.getSession(user, host, port);
session.connect();
Channel channel=session.openChannel("sftp");
channel.connect(); --------------------------------------------debugging
has shown that the process hangs here
ChannelSftp c=(ChannelSftp)channel;
And throws this error:
com.jcraft.jsch.JSchException: java.io.IOException: channel is broken
at com.jcraft.jsch.ChannelSftp.start(ChannelSftp.java:242)
at com.jcraft.jsch.Channel.connect(Channel.java:200)

It fails using both 1.40 and 1.42 jars. Asking for the logs from the host
company has resulted in an TCP Reset-O error on their side. I can connect from
the command line using the seeded SFTP script, it is just the jcraft version
that is failing.
Please help if you have any suggestions.
