The rsh state engine is used for remote shell (rsh) sessions. This state engine understands the control protocol used by these sessions, including the enabling of the TCP connection used for stderr messages. The rsh service is typically the only service that uses this state engine. The discriminator for the rsh state engine is the port number of the RSH server. This is normally 514.
The rsh state engine has one parameter:
Lifetime of idle session in seconds - Specifies the lifetime of an idle session (default = 86400 seconds or 24 hours)
