Software updates
The AT&T Global Network Client periodically checks for and downloads updates to the Hotspot Directory
and the executable program using anonymous FTP (TCP ports 20/21).
The program update for AT&T Global Network Client, starting in version 7.4.0, should automatically query
the user during the connection sequence to retrieve the applicable network settings. The Service
Manager will then send the information to the AT&T Global Network Client and enable or restrict
program updates based on VPN Client ID and other information provided by the user. This action
prevents the user from inadvertently downloading a program update if there is a custom program update
available applicable to their Client ID. It also enables the Network Administrator to control if users are
able to “Check for Updates” and therefore reduces the risk of different users being on different versions
of the AT&T Global Network Client.
Figure 98: Software Updates
For customers that use the AT&T Global Network Client for the Internet service without an Account or
User ID, program updates will always be available.
SLA data collection
The AT&T Global Network Client uploads data about all connection attempts using HTTP (TCP:80) to a
server after connecting. This data is used for measuring SLAs (Service Level Agreements). If the SLA data
is not collected, AT&T will not provide service-level guarantees.
AT&T requires companies to add policy rules to the company’s firewall to allow SLA data to be sent to
those servers.
Configuration Updates
The AT&T Global Network Client requests configuration settings (like start page, e-mail server, proxy
server, etc) from an AT&T Administration Server. The AT&T Global Network Client updates third-party e-
mail and browser programs with these settings. AT&T recommends adding policy rules to the firewall to
allow updates to be retrieved.
