Step 2: Direct The Thin Client To The Server; Using Dhcp - Dell Wyse Enhanced Ubuntu Linux T50 User Manual

Step 2: Direct the Thin Client to the Server

After you set up the folder structure and populate it with the correct files, you must
then direct the thin client to the location of the server by one of the following ways:
DHCP (see "Using DHCP")
•
Manual direction (see "Manually Configuring the Server Location")
•
IMPORTANT: Using DHCP is strongly recommended.

Using DHCP

When using DHCP to direct the thin client to the location of the server
(recommended), information about the server and root directory is obtained from the
following DHCP options:
161 - The server.
•
162 - Root path to the server (ftp/http/https).
•
If no root path is defined, /wyse is assumed.
·
If a root path is defined, the additional path will be appended to the URL supplied
·
by option 161.
184 - (Optional) Server username (to server specified in option 161).
•
185 - (Optional) Server password (to server specified in option 161).
•
TIP: Check-in for configuration changes is done early in the boot process. For that
reason, changes in DHCP information may not be propagated to a unit until a full boot
is completed. However, you can avoid this by forcing a renewing of the DHCP lease,
which makes sure that the unit has the latest file-server location before the next check.
Simply, right-click the Network Manager icon, click Enable Networking to disable it,
right-click the Wireless Manager icon, and then click Enable Networking to enable it
again (the DHCP lease is renewed).
TIP: For general instructions on adding DHCP Options #161 and #162, refer to
Knowledge Base Solution #16132 (go to the Knowledge Base at
