Host Validation (Heartbeats)

Host heartbeats work in two stages:

First, a ping request will be sent to the remote host on the ICMPv4 protocol. This does not require a port to be open on the remote machine, however the firewall on the remote host can have a rule to block ICMPv4 requests.

If the ping test fails, Passwordstate attempts to do a new open port test on the remote session connection protocol, which by default is 3389 for RDP and 22 for SSH.

If both tests fail, the heartbeat is considered a failure.
