afmserver - the multi-stream server of the afbackup package


afmserver [ <options> ] [ <configuration-file> ]


The multi-stream server able to serve several clients in parallel. This program works as a protocol multiplexing frontend for the normal server, that in turn is started as backend in slave mode. For the client side this server looks exactly like the normal single stream server, so for them there is nothing special contac- ting the multi stream server. The clients must pass a unique identifier to the multi stream server. Otherwise it cannot distinguish the clients, especially when dispatching the data on tape to the clients. By default this identifier is the official hostname of the client, that is determined from the connection. A client may pass a different identifier after having connected and authenticated successfully. The options are identical to those of the server program except for option -S, that is not applicable here, cause the multi-stream server doesn't know a slave mode. The other options are also passed to the server backend (see: afserver(8)), except for the following, that are understood only by mserver:

Daemonize. Go into the background and run forever. This is the way, the multi stream server can be started without using the inetd. -p should be supplied when using this option
-p <port>
The TCP port number or service name, the server should bind to. If started via inetd, the inetd binds to the port and starts the mserver connected to the port. When started as daemon, the mserver must be told the port to bind to. If not given, the service entry afmbackup is used or, if not found, the default port 2989
