[JSch-users] Exec channel session hanging on disconnect

[bode o. <bod...@ho...>]

I'm execing a command via ssh and reading an error response using 
getErrStream. However, it seems to hang .Any ideas please?

try{
	channel=session.openChannel("exec");
	((ChannelExec)channel).setCommand(command);						((ChannelExec)channel).setErrStream(System.err);
	err = ((ChannelExec)channel).getErrStream();
	InputStreamReader istreamreader = new InputStreamReader(err);
	BufferedReader breader = new BufferedReader(istreamreader);
	String error= "";
	channel.setInputStream(System.in);
	channel.connect();
	while(true)
	{
		if(channel.isClosed())
		{
			if ((error = breader.readLine()) != null)
			{
				throw new Exception(error);
			}
			break;
		}

	}
}
catch(Exception ex)
{}
finally{
		try
		{
			channel.disconnect();
			err.close();
			breader.close();
			istreamreader.close();
		}
		catch(Exception e){}

}
