DHCP image update

If you want to use DHCP image update, the thin client requires no configuration or setup because the

DHCP options provide all the necessary configuration information and direct the thin client to begin the

update process. Linux thin clients that support this feature use the following options that you must config-

ure on the DHCP server:

Option 180: FTP_FORCE_IMAGE_ON - type string; value TRUE to enable

Option 181: FTP_SERVER - type IP; value ip address

Option 182: FTP_SERVER_PATH - type string; value base path

Option 183: FTP_USERNAME - type string

Option 184: FTP_PASSWORD - type string

You must create a shared folder on the FTP server. You can use two main paths on the FTP server to create

a shared directory path:

•

<FTP root>/linux/<imageid>/image/

for flashing images.

•

<FTP root>/linux/L

x

other/image

for flashing alternate images, where the

x

in

l

x

other

indi-

cates the size of the image and its associated thin client, as follows:

•

1 = 32-MB image (HP Compaq t5125)

•

3 = 128-MB image (HP Compaq t5515 - 128-MB model)

•

4 = 256-MB image (HP Compaq t5525)

Definitions of the fields in these paths are as follows:

•

<FTP root>

: Shared directory on the FTP server where you can find the new image files.

•

<Linux>

: System-defined directory that must be present below the FTP directory on the FTP server.

•

<imageid>

: Directory with the same name as the image version from which you wish to upgrade,

which you can find in the System utility in the XFce Settings Manager (for example, L1ST3149,

L4ST3149, etc).

•

<image>

:

System-defined directory that contains the image to which you want to upgrade.

•

<L

x

other>

:

Alternate system-defined location that may contain the image to which you want to

upgrade, where

x

indicates the size of the image as defined above.

For example, to upgrade a t5125 from image L1ST3149 using an FTP server with a directory titled

/hp/tc

, place the new image in

/hp/tc/linux/L1ST3149/image

on the FTP server.

NOTE

: To prevent FTP Image Upload from running an endless loop of reimaging the thin client, when

using the

Lxother

directory, you must create a file named

skip

in the

<FTP root>/linux/

<imageid>/image

directory.
