[Eshwara]

Hi team,

line 1 : 1 device = new Device("VNF", deviceuser, deviceIP, port);
line 2 : device.setDefaultReadTimeout(10 * 60 * 1000); // 10 minutes
line 3 : device.connect(username);

application got hang when it reached line 3. please find the thread dump below. anything we can do to avoid hang issue( waiting issue). it waits indefinitely and not able to come out that.

Could be various reasons I guess, starting with connectivity, up to wrong credentials or some fw blocking?
Is your device reachable from the device where you try to run JNC code?
Can you check device/server logs on the target device?
See if the incoming connection is visible/logged at target SSH/NETCONF server and any problems reported?
edit: oops - seems to be addressed in #132
