Schedules work for the Basic Networking Utilities (BNU) file transport program.
uusched [ -uDebugLevel ] [ -xDebugLevel ]
The uusched daemon schedules work for the Basic Networking Utilities (BNU) file transport program. It schedules the transfer of files that are queued in the /var/spool/uucp/SystemName directory. The scheduling daemon first randomizes the work and then starts the uucico daemon, which transfers the files.
The uusched daemon is usually started by the uudemon.hour command, a shell procedure, which is run periodically by the cron daemon based on instructions from the /var/spool/cron/crontabs/uucp file.
The uusched daemon can also be started from the command line for debugging purposes.
Note: Either you must be in the /usr/sbin/uucp directory when you start the uusched daemon, or you must start the daemon with the full path name, /usr/sbin/uucp/uusched.
| -uDebugLevel | Passes as the -xDebugLevel flag to the uucico daemon. The DebugLevel variable is a number from 0 to 9, with a default of 5. Higher numbers give more detailed debugging information, which is displayed on the screen of the local system. |
| -xDebugLevel | Outputs debugging messages from the uusched daemon. The DebugLevel variable is a number from 0 to 9, with a default of 5. Higher numbers give more detailed debugging information, which is displayed on the screen of the local system. |
To start the uusched daemon from the command line, enter:
/usr/sbin/uucp/uusched &
This starts the uusched daemon as a background process. (Note that the path name is included in the command.)
