RLOGIN is a "remote login" facility for sysops.
The secure password challenge/response mechanism, using
the "@" command, is inconvenient for frequent use, and
unnecessary in cases where the remote sysop can access
the router via a "secure" link such as a wire link between
two systems. RLOGIN provides a connection with a plain
text password system for these situations.
RLOGIN uses a Telnet connection to TCP port 513. This
port may be moved or disabled using the RLOGINPORT
directive in XROUTER.CFG if required.
Upon connection, the sysop is prompted to enter his
callsign, and is then asked for his password. If the
two match with an entry in PASSWORD.SYS, the sysop is
granted access with full sysop status.
