z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

Security
Localization
Files
For example, the following command will not do what you expect because “hello”
will be treated as a file unless enclosed in parentheses.
uux "Remote!echo hello >test.out"
The correct way to enter that command is:
uux "Remote!echo (hello) >test.out"
1. Suppose that a neighboring site, south, has a program called laser for printing
and formatting documents. You have execute permission for laser. To print the
file inventor.y in south’s public UUCP directory using south’s laser program:
uux south!laser ' ~/inventor.y'
The tilde needs protection from shell expansion.
To print the file report.001 in your public UUCP directory:
uux south!laser ! ~/report.001
2. Suppose you have execute permission for uucp on south. To request that south
use uucp to copy the file index from its public UUCP directory to west, a
neighbor of south:
uux south!uucp \(~/index\) \(west! ~/\)
The arguments ~/index and west! ~/ are not interpreted by uux because of
the parentheses. The backslashes are necessary to escape the parentheses on
the z/OS shell.
uux is potentially a security risk to your system. UUCP minimizes the risk by
allowing you to specify the commands that can be run by each remote site. (See
the section on Permissions files in z/OS UNIX System Services Planning for more
information.)
For electronic mail, each remote site must be able to execute a mail routing agent
on your site. Further permissions can be granted at your discretion.
uux uses the following localization environment variables:
v LANG
v LC_ALL
v LC_CTYPE
v LC_MESSAGES
See Appendix F for more information.
uux uses the following files:
/usr/lib/uucp/config
UUCP configuration file
/usr/spool/uucp/site
Subdirectory containing queued job requests, work files, data files, and
execution files for the UUCP host site.
/usr/spool/uucp/LOGFILE
Log file for uux and other UUCP utilities.
