how to disable keepalive function? #378

Open CapBarbossa opened 1 year ago

CapBarbossa commented 1 year ago

IMPORTANT NOTE I want to disable keepalive function to keep tunnel regardless of whether remote machine is down.

Describe the bug I set keepalive 0 0 in server configuration, but NOT specified the same in client configuration. After launching server and clients, clients first got private IP as expected, but in following 40~60 minutes, clients kept requesting IP addresses from server, ending with failure, and both server and clients couldn't work anymore. This keepalive 0 0 solution is from chatGPT, which I doubt if it is bullshiting. In official documents, I didn't find any double 0 settings mentioned.

To Reproduce In configuration on server side: keepalive 0 0

Expected behavior The tunnel established persist, can NOT be ended automatically.

Version information (please complete the following information):

Additional context Nothing else.

Relying on ChatGPT for proper information is weird to say the least. Just leaving out keepalive/ping options works just as well.

You also provided no evidence that disabling keepalive is not working. There are other timeouts etc. that will break a connection eventually. keepalive is just designed to detect a broken connection early.
