Dialing Prefixes
This file contains the dial-code abbreviations used in the L.sys file (e.g., py, mh,
boston). The entry format is
abb dial-seq
where abb is the abbreviation and dial-seq is the dial sequence to call that
location.
The line
py 165
would be set up so that entry py7777 would send 1657777 to the dial unit.
Userfile
This file contains user accessibility information. It specifies four types of
constraints:
1. Files that can be accessed by a normal user of the local machine.
2. Files that can be accessed from a remote computer.
3. Login name used by a particular remote computer.
4. Whether a remote computer should be called back in order to confirm
its identify.
Each line in the file has the format
login,sys [c] pathname [pathname] .../
where
login
sys
c
pathname
The constraints are implemented as follows:
1. When the program is obeying a command stored on the local
machine, the pathnames allowed are those given on the first line in
the USERFILE that has the login name of the user who entered the
command. If no such line is found, the first line with a null login is
used.
2. When the program is responding to a command from a remote
machine, the pathnames allowed are those given on the first line in
the file that has the system name that matches the remote machine.
If no such line is found, the first one with a null system is used.
is the login name for a user or the remote computer.
is the system name for a remote computer.
is the optional call-back required flag.
is a pathname prefix that is acceptable for sys.
