This module periodically sends XEP-0199 ping requests to remote servers to keep your connection alive.
Simply add the module to the
modules_enabled list like any other module. By default, all current s2s connections will be pinged periodically. To ping only a subset of servers, list these in
keepalive_servers. The ping interval can be set using
If no response to the ping has been received in about 10 minutes (or
keepalive_timeout seconds) the s2s connections are closed.
