Introduction; Uucp Unix To Unix File Copy - Sun Microsystems Sun Workstation 100U System Manager's Manual

1. Introduction
Vuep is a series of programs designed such that
UNIXt
systems can communicate with each
other using either dial-up or hardwired communication lines. Vuep transfers files between UNIX
systems, and can also run commands on remote machines. The first version of the system was
designed and implemented by M. E. Lesk. This paper describes the current (second) implemen-
tation of the system. This document gives a detailed description of the current implementation
of uuep. It is designed tor use by an administrator or installer of the system. It is not meant
as
a user's guide.
Vuep is a batch operation. Files are created in a spool directory for processing by the uuep dae-
mons. There are three types of files used for the execution of work: Doto file. contain data for
transfer to remote systems; Work file. contain directions for file transfers between systems;
Ezeeute file, are scripts for UNIX commands that involve the resources of one or more systems.
There are four primary programs involved in uuep's operation:
uuep builds work file, and gathers doto file, in the spool directory for data transmis-
sion.
uuz
uueleo
uuzqt
creates work file, and ezeeute file" and gathers doto file, for the remote execu-
tion of UNIX commands.
executes the work files
tor
data transmission.
executes the scripts for UNIX command execution.
There are two administrative programs:
uulog gathers temporary log files that may occur due to lockout of the uuep log file
and reports some information such as copy requests and completion status.
uuclean removes old files from the spool directory.
The remaining sections of this manual describes the operation of each program, security, instal-
lation details, files required for execution, and administration of the uuep system.
2. UUCP - UNIX to UNIX File Copy
The uuep command was is designed to look like ep(l) to the user. The syntax is:
uuep [option] ... source. . . destination
where the source and destination may contain the prefix 'lI,tem-nome!, which indicates the sys-
tem where the file or files reside or where they will be copied.
Vuep has several options:
-d
Make directories when necessary for copying the file.
Don't copy source files to the spool directory, but use the specified source when
the actual transfer takes place. Note that the files, and all directories leading to
them, must be accessible by everybody.
Send this job to system
'II'
to execute. Note that this only works when the sys-
tem '11' allows uuzqt to execute a uuep command. See the sections entitled
Vuzqt and Security.
