Enum Monitor 

pub enum Monitor {
    Disabled,
    Loop {
        port: u16,
    },
    Echo {
        port: u16,
        echo: u16,
    },
    Unix,
}

How the connection is monitored.

Variants

Disabled

-M 0: no monitoring; react only to ssh exiting and to signals.

Loop

-M port: a loop of forwardings. Write to port, read back on port + 1.

Fields

port: u16

Echo

-M port:echo: a remote echo service. port carries both directions.

Fields

port: u16

echo: u16

Unix

-M unix: the same loop, over UNIX-domain sockets. No ports to pick and none to collide, at either end.

Implementations

impl Monitor

pub fn forwards( &self, host: IpAddr, unix: Option<&UnixPaths>, remote_sock: &Path, ) -> Vec<OsString>

The ssh arguments that build the monitor path (§1.3 of the plan).

unix and remote_sock are consulted only for Monitor::Unix, where the remote path is different on every ssh start.

pub fn write_port(&self) -> Option<u16>

The port rash writes its probe to, if it uses one.

pub fn read_port(&self) -> Option<u16>

The port rash listens on for the probe to come back, if it uses one.
