Multihost Mode

Using the MSS

There are a few important things to note about multihost connections:

¥The MSS will pingTCP and UDP hosts before sending packets to make sure the remote hosts are alive. If they are alive, the MSS makes the real connection and passes the data. If any of them arenÕt alive, the MSS doesnÕt connect or retry.

¥If one of the host connections is terminated prematurely, the MSS will attempt to reconnect at preset intervals. If a UDP connection attempt receives an ICMP Unavailable message, the MSS will wait ten seconds before retrying. The waiting period for Telnet and Rlogin is 120 seconds, and for LAT it is 30 seconds.

¥If a hostÕs ßow control blocks the MSS from sending, the MSS will not send any serial data to that host, but it will send the data to the other hosts in the host list. The MSS consults all hosts each time it has data to send; it doesnÕt keep track of which hosts wouldn't accept data in the past.

¥When the MSS serial port is logged out, all host sessions are disconnected and the port becomes idle. Depending upon the portÕs Autostart setting, it will either wait for serial data (Autostart disabled) or start the connection again immediately (Autostart enabled).
