Using telnet
Telnet access is available to run shell scripts or use shell commands but only
advanced users should use telnet. An advanced user is someone who is proficient
in the internal workings of the Unix operating system.
The RaQ 4 Administrator can enable the telnet feature for a virtual site. If the
telnet feature has been enabled, the Site Administrator can then enable telnet
access for individual site users; see “User management” on page 97.
