Hi,

|I am outside this network, but I have an IP address of one of those gateway
nodes. To
|access any of the non-gateway nodes, our program until now opened an JSch
Session
|(gateway) to the gateway node, and then used
|
| gateway.setPortForwardingL(localPort, ipNode, 22);
|
|with a random local port. Then it opened a new Session:
|
| jsch.getSession(username, "127.0.0.1", localPort);
|
|This worked fine (but seemed to neccesiate
setConfig("StrictHostKeyChecking", "no"),
| since all connections now did go to 127.0.0.1).
The following will be better in that scenario,
int localPort = gateway.setPortForwardingL(0, ipNode, 22);
Session session = jsch.getSession(username, "127.0.0.1", localPort);
session.setHostKeyAlias(ipNode);
...
And then, the following change my do the trick,
public void connect(SocketFactory ignore, String host,
int port, int timeout)
throws Exception {
activator.logInfo("setup tunnel through gateway to " +
host +":"+port + "...");
channel =
(ChannelDirectTCPIP)gateway.openChannel("direct-tcpip");
channel.setHost(host);
channel.setPort(port);
iStream = channel.getInputStream(); // !!
oStream = channel.getOutputStream(); // !!
channel.connect();
// iStream = channel.getInputStream();
// oStream = channel.getOutputStream();
activator.logInfo("tunnel to "+host +":"+port + "
established.");
}
Sincerely,
