NAME
uucheck - Checks for files and directories required by uucp SYNOPSIS
uucheck [-v] [-xdebug_level] FLAGS
Displays a detailed explanation of how the uucp program interprets the permissions file. Displays debugging information. The valid range for debug_level is 0 to 9. The higher the number, the more detailed the final report. DESCRIPTION
The uucheck command verifies the presence of the files and directories required by the uucp program. In addition to checking for the pres- ence of files required by uucp, the uucheck command also checks for some errors in the /usr/lib/uucp/Permissions file. The uucheck command does not check for correct file and directory modes or for errors in the /usr/lib/uucp/Permissions file, such as dupli- cate login or machine names. When the uucp program is installed, uucheck verifies that the directories, programs, and support files required to operate the networking facility are present. The command is executed automatically, as one of the first steps in the installation process, before the required uucp directories, programs, and files are actually installed. Issue the uucheck command from the command line after installing uucp, configuring uucp for your site, or making changes in part of the uucp program, such as the /usr/lib/uucp/Permissions file. Note that the uucheck command can only be issued from the command line if you have superuser authority. EXAMPLES
To find out how the uucp program interprets the /usr/lib/uucp/Permissions file, enter: uucheck -v The -v flag instructs the uucheck command to verify that the uucp files exist and displays a detailed explanation of how the uucp programs interpret the permissions file. To set the debug level to 8, enter: uucheck -x8 FILES
Specifies the command path Information about available devices Limits scheduled jobs Limits remote command executions Describes access per- missions for remote systems Describes accessible remote systems Spooling directory Public directory Prevents multiple use of device nn RELATED INFORMATION
Commands: uucico(8), uusched(8), uucp(1), uustat(1), uuto(1), and uux(1) delim off uucheck(8)
