santhsr opened a new issue, #460:
URL: https://github.com/apache/mina-sshd/issues/460
### Version
2.9.2
### Bug description
Im getting time out exception after 10 min . If the command executes before
ten minutes the program is working as expected.
### Actual behavior
public static void main(String[] args) throws IOException,
InterruptedException {
SshClient sshClient = SshClient.setUpDefaultClient();
sshClient.setForwardingFilter(new AcceptAllForwardingFilter());
sshClient.start();
//if (connectFuture.isConnected()) {
// SSH connection is established
ClientSession session = sshClient.connect("root", "XXXX",
22).verify().getSession();
session.addPasswordIdentity("yyyy");
session.auth().verify();
//Setting up env variables
ChannelExec channel = session.createExecChannel("sleep 20m");
//channel.setOut(new NoCloseOutputStream(System.out));
//channel.setErr(new NoCloseOutputStream(System.err));
channel.open().verify(30, TimeUnit.MINUTES);
System.out.println("*******************");
// Wait (forever) for the channel to close - signalling shell
exited
channel.waitFor(EnumSet.of(ClientChannelEvent.CLOSED), 0L);
while (!channel.isClosed()) {
Thread.sleep(1000);
}
int exitCode = channel.getExitStatus();
//}
}
### Expected behavior
The program should run with out exception
