The server tries every <ConnectRetry> seconds to establish a link to not yet
(or no longer) connected servers. Default: 60.

+\fBIdleTimeout\fR (number)
+Number of seconds after which the whole daemon should shutdown when no
+connections are left active after handling at least one client (0: never). This

+with systemd(8), for example. Default: 0.
+.TP
\fBMaxConnections\fR (number)
Maximum number of simultaneous in- and outbound connections the server is
allowed to accept (0: unlimited). Default: 0.
