Software Repository Installation Tips You Need to Know
Depending on how you are installing, use the following guidelines when prompted for
Repository configurations during an installation or upgrade:
Tip
If your network has multiple subnets, consider deploying a copy of the WDM
Software Repository (Repository) on each subnet to allow you to store large
device applications and image files locally. When upgrades are distributed to
devices on a subnet from a local repository, network traffic is reduced.
• When selecting the protocol to use for repository communication - use the
following guidelines (Note that the wizard attempts to connect to your FTP service to
ensure connectivity and read/write permissions; WDM only verifies an existing
connection; it does not configure your FTP service.):
·FTP - Select this option if you want WDM to download packages from the repository
using the FTP protocol. CAUTION: If you intend to use the firmware upgrade
feature for Wyse ThreadX devices, FTP must be configured.
If you are using an existing FTP service, the wizard prompts you for an IP Address,
username, and password.
If you are using an existing IIS FTP service, the wizard creates a local WDM user
and assigns the user read/write permissions to the IIS FTP service.
· HTTP - Select this option if you want WDM to download packages from the
repository using the HTTP protocol.
· FTP and HTTP - Select both options if you want WDM to download packages from
the repository using either the FTP or HTTP protocol. If both options are selected,
HTTP is attempted first; if HTTP fails, the FTP protocol is then attempted.
Tip
HTTPS can be enabled/configured later on an HTTP repository.

• When selecting the authentication option(s) to apply to software repositories -
use the following guidelines (note that you can select any or all of the options; if you
select all three options, Windows Authentication is applied.):
· Anonymous Access - This mode does not require a username or password to
access the repository.
· Windows Authentication - This is the most secure form of authentication in IIS.
When you log in, Windows NT validates your login and only your username is
transmitted over the network. Your password is not transmitted.
