registered with a DNS server before other thin clients will be able to locate this LPD
server). The thin client does not dynamically register its name and the DNS registration
must be manual.
•Wyse Device ManagerTM (WDM) Guidelines - If you use WDM, the thin client uses
port 80 as the default to access a WDM server (formerly known as Rapport server). If a
port other than 80 is used to access a WDM server, use option 187 in the list of DHCP
options in Table 1 (option for a WDM server is option 186 in the list of DHCP options in
Table 1). WDM options are the only options used by the thin client that are not in text
•PNAgent/PNLite Server Guidelines - If you use a a PNAgent/PNLite server, the thin
client uses port 80 as the default to access a PNAgent/PNLite server. If a port other
than 80 is used to access a PNAgent/PNLite server, the port number must be specified
explicitly with the server location in the form IP:port or name:port (option for a
PNAgent/PNLite server is option 181 in the list of DHCP options in Table 1).
•Windows DHCP Server Guidelines - You can use the DHCP tools available on the
•Linux DHCP Server Guidelines - For Linux servers, enter DHCP options 161 and 162
(described in Table 1) in /etc/dhcpd.conf (refer to the manual page man
dhcpd.conf for more information on DHCP and the syntax of this file). For example, if
you want the computer to search ftp://22.214.171.124/pub/
serversoftware/wnos, add the following line to /etc/dhcpd.conf:
option option-161 126.96.36.199;option option-162 "pub/
As mentioned in Table 1, the /wnos suffix is automatically appended to the FTP path,
so you should not specify it explicitly. In this case, the actual directory searched will be
•DHCP Options Guidelines - Wyse ThinOS uses several DHCP option tags. These
option tags must be created, activated within the DHCP scope(s), and then added for
the thin clients to use them. Figure 3 shows the Windows DHCP Server Predefined
Options and Values dialog box that is displayed when right-clicking the DHCP server
and selecting Set Predefined Options. The most commonly used tags are 161 and
186. Depending on the Terminal Server environment, more options can be added
using the Predefined Options and Values dialog box.

Use the guidelines shown in Table 1 when creating and adding the DHCP option tags you
need for your thin clients.
