The common SSH daemon tool found on most Linux distributions makes this process easy to handle and additional shell settings even offer the ability to disconnect idle. The data source waits the given number of timeout milliseconds for a response from the network. Thus, the system will uses the detected MTU for transmissions. To make tcp check with defined timeout, you can use this UserParameter for *nix hosts:. I think that this 8 hours is not a sort of timeout but concretely the Re-Authentication period.
