System Overview
RASExpress and Auxiliary Software
The CommPlete 4000 is equipped with factory installed RASExpress, an advanced remote access
software that enables network managers to configure and manage remote servers via web browsers,
through Telnet over an IP network, and via a GUI manager over both IP and IPX networks. Through a
special software package bundled with the CommPlete 4000, RASExpress can also be interfaced to
standard Radius authentication functionality (which resides on a separate PC).
RADIUS authentication software (Remote Authentication Dial-In User Service) handles authentication
and profile information about network users and secures against unauthorized server access. Built-in
R log protocol support permits remote log-in to all hosts on the network. RASExpress can facilitate
remote software upgrades via standard TFTP protocol.
The CommPlete 4000s workstation re-director programs (WINMCSI and MCSIWSN) control modem
port assignments on the network.
