USER-TELNET-SERVER                                      19-Jan-1998/a.l.

A sample, unsupported, "user-written" TELNET server.  This can be used
to fire off an autologin'd job in response to a TCP connect to a 
given port.

To build USER-TELNET-SERVER.C, @buildit.

To use, use MULTINET CONFIG/SERVER to specify this as being
invoked by connections to some TCP port:

    SERVER-CONFIG>show auto/full
    Service "AUTO":
        TCP socket (AF_INET,SOCK_STREAM), Port 9999
        Socket Options = SO_KEEPALIVE
        INIT() = TCP_Init
        LISTEN() = TCP_Listen
        CONNECTED() = TCP_Connected
        SERVICE() = Run_Program
        Program = "AA_SOURCE:[MNET.AUTOLOGIN]USER-TELNET-SERVER.EXE"

Selection of what username to autologin to is based on logical names:

$ DEFINE /SYS MULTINET_AUTOLOGIN_9999_USERNAME MELVIN

will make connects to port 9999 autologin to MELVIN.  (If the
servicename is defined in HOSTS.LOCAL, then 
$ DEFINE /SYS MULTINET_AUTOLOGIN_servicename_USERNAME MELVIN
will work.)  You could then make MELVIN be CAPTIVE, and have
MELVIN's LOGIN.COM execute a given application, to allow
for public access to a canned application.

If no specific username is defined for the port, the logical
MULTINET_AUTOLOGIN_USERNAME will be checked.  If no logical
is found to map to a username, connections to the port will
be greeted with a "Username:" prompt.

This has been built under VMS V6.1, VAXC V3.2, MultiNet V3.3D.
Your results may vary.
