USRobotics NETServer/8 - Manual (Page 16)

1-8 Overview
Security
The NETServer supports IP and IPX packet filtering in both the
inbound and the outbound directions of ports, users, and dial
out locations. Packet filter configuration is discussed in Chapter
8.
The NETServer also supports the use of a centralized RADIUS
security server, allowing you to create a single account for each
user rather than multiple user accounts on multiple NETServers.
RADIUS security is discussed in Appendix F.
Administrative Utilities
The NETServer’s command line includes an assortment of
utilities for troubleshooting connections including:
•
The ability to manually dial a location to test connectivity
•
The ability to use Telnet, Rlogin or PortMux to establish a
session with another host from the NETServer’s command
line.
•
UNIX-like troubleshooting commands including ifconfig,
ptrace, ping and traceroute for debugging IP connections.
These commands are contained in Chapter 9, along with
instructions for customizing the supervisor account.
