Contain data to be sent to remote systems.
Data (D.*) files contain the data to be sent to remote systems by the Basic Networking Utilities (BNU) uucico daemon. The full path name of a data file is a form of the following:
/var/spool/uucp/SystemName/D.SystemNamexxxx###
where the SystemName directory and the SystemName portion of the file name indicate the name of the remote system. The xxxx### notation is the hexadecimal sequence number of the command (C.*) file associated with that data file, for example: D.venus471afd8.
After a set period of time (specified by the uusched daemon), the uucico daemon transfers the data file to the designated system. It places the original data file in a subdirectory of the BNU spooling directory named /var/spool/uucp/SystemName, where the SystemName directory is named for the computer that is transmitting the file, and creates a temporary (TM.*) file to hold the original data file.
After receiving the entire file, the BNU program takes one of the three following actions:
Item | Description |
---|---|
/etc/uucp/Systems | Describes accessible remote systems. |
/var/spool/uucp/SystemName directory | Contains BNU command, data, and execute files. |
/var/spool/uucp/SystemName/C.* | Contains instructions for file transfers. |
/var/spool/uucp/SystemName/TM.* | Stores data files temporarily after they have been transferred to a remote system. |
/var/spool/uucppublic/* directory | Contains files that the BNU program has transferred. |
