Though a very basic, a very missing feature of Calitko. With current settings, a connection will be automatically closed if no packet has been received for the last minute. TCP may not signal that a connection is terminated even though the physical link is no longer available. An example is when you unplug your cable.

I tested the feature between two Calitko nodes connected only to each other and ‘unfortunately’ it worked! I say unfortunately, because this means neither of both generated any traffic meaning that neither a direct ping, nor a pong cache refresh ping was ever sent out. This needs further investigation!
