4.17 The uucp Utility
The DIGITAL UNIX system has the uucp utility for copying between UNIX
systems. The uucp utility allows you to transfer data from one system to
another, and to execute commands on a remote system. Connections using
the uucp utility can handle data communication over a wider geographic
area than a LAN and usually transmit the data through telephone
connections.
The uucp utility on DIGITAL UNIX systems is different in some ways from
the uucp on ULTRIX systems. On DIGITAL UNIX systems, the uucp
utility is the HoneyDanBer uucp. (The name HoneyDanBer is derived from
the names of the authors of this version of uucp, Peter Honeyman, David
A. Nowitz, and Brian E. Redman.) Also, uucp communications is supported
over the TCP/IP protocol.
On both systems, you use the uucpsetup command to set up the uucp
utility. The DIGITAL UNIX command is similar to the ULTRIX command,
except that it has been modified to be consistent with the DIGITAL UNIX
version of uucp. For information about using the uucpsetup utility, see
the Network Administration manual.
The files that store uucp information and the scripts that control uucp on
a DIGITAL UNIX system are in different locations and, in some cases,
have a different format from the files and scripts on an ULTRIX system.
The following list details the differences:
• System information file
Information about which systems uucp calls out to is stored in the
/usr/lib/uucp/Systems file on DIGITAL UNIX systems, rather than
the /usr/lib/uucp/L.sys file. The format of the DIGITAL UNIX
Systems file is different from the L.sys file on ULTRIX systems.
• Device information file
On DIGITAL UNIX systems, the file that stores device information is
the /usr/lib/uucp/Devices file. On ULTRIX systems, device
information is stored in the /usr/lib/uucp/L-devices file. The
format of the Devices file is somewhat different from the format of the
L-devices file.
• Security information file
On DIGITAL UNIX systems, the /usr/lib/uucp/Permissions file
stores information about which systems can access the local system and
about which commands can be executed locally. The Permissions file
allows you greater control (than you had on an ULTRIX system) over
how individual systems can access the local system.
