of the
master ERA Server into the
Upper server
field - the IP address of the GHOST server, in our example.
7.2.3 Subsidiary: Installation of HTTP Mirror server
The Mirror server installation example of the previous model can also be used in this case. The only changes are in
the sections defining:
•
Source of update files
•
User name and Password
As seen in Figure 14, updates for the subsidiary are not downloaded from ESET’s update servers, but from the
server at the headquarters (GHOST). The update source is defined by the URL address:
http://ghost:2221
(or
http://
IP_address_of_ghost:2221
).
By default, there is no need to specify a user name or password, because the integrated HTTP server requires no
authentication.
