DEBUG: Outgoing: Writing ping (GLOBAL_REQUEST: 17:18:05 GMT+0200 (CEST)] DEBUG: Outgoing: Writing CHANNEL_WINDOW_ADJUST (3, 524365) DEBUG: Outgoing: Writing CHANNEL_WINDOW_ADJUST (3, 524355) DEBUG: Outgoing: Writing CHANNEL_WINDOW_ADJUST (3, 524310) DEBUG: Outgoing: Writing CHANNEL_DATA (3) The whole reason for this keepalive mechanism is to allow for configurable (shorter) connection timeouts, since the default TCP keepalive timeouts on all operating systems are set to very high values and node currently does not expose the necessary OS APIs to fine tune the TCP keepalive settings (IIRC this is mostly because not all platforms - or kernel versions in the case of *nix - expose such APIs). Setting high maximum (as explained in my first point) keepalive settings (both counts and intervals) can lead to excessively long wait times when there is a dead connection. It's not clear what you're asking for here. You should still receive a 'close' event though, since the socket is destroyed after the 'error' event is emitted. This is similar to other abnormal (TCP-level) connection issues such as connection timeouts, unexpected connection resets, etc. It emits 'error' because otherwise you'd have no way of knowing that the connection is being terminated abnormally. This is actually what the server implementation's keepalive mechanism already does. Right now the situation for the client implementation could be improved a bit by resetting keepalive on receipt of any packet (not just a response to "ping" requests). The number of unanswered "pings" gets reset to 0 whenever we see a response from the server. remote server abruptly stopped, local network connection disconnected, etc.). If you set this too high then you could end up waiting a long time if the connection really is dead (e.g. the server could just be temporarily overloaded). If you set this too low you could cause a valid connection to closed early (e.g. The SSH server implementation itself can be found on Github here: there needs to be some threshold to determine how many unanswered requests constitutes a dead connection.
