FTP Update Process
When a FTP update is initiated on the Mantis, either by selecting
from the menu system or by a regular update interval
Update Now
or fixed time trigger, the Mantis attempts to establish
communications with the specified FTP site.
When communication is established, the Mantis searches the home
directory for update packet files intended specifically
/scripts
for that particular Mantis. The filename is the site ID for the
Mantis performing the update. For example, if the site ID of the
Mantis is location1, the Mantis looks for a file location1.tar. When
the Mantis finds the file, it copies it and then progresses to the
playlist parsing routine, see page 106.
However, if the Mantis does not find an update packet file, it then
searches for a generic package file with the filename firefly.tar.
When the Mantis finds this file, it copies the file and moves on to
the parsing routine, see next page.
FTP Updating Order
The Mantis system looks for an update file following a specific
order. It proceeds sequentially through the order until it finds a
matching file and then proceeds to the playlist parsing routine, see
below.
1. siteid.tar
2. firefly.tar
3. siteid.fpl
4. firefly.fpl
5. siteid.fsc
6. firefly.fsc
