Table 4. DHCP options (continued)
Option Description Notes
against a domain not in the list, the
user has the option of not using any of
the domains specified in option 182 and
typing a different domain name at the
time of login.
184 File server Username
Optional string. Username to use when
authenticating to the server specified in
Option 161.
185 File server Password
Optional string. Password to use when
authenticating to the server specified in
Option 161.
186 WDM server list
Optional binary IP addresses of WDM.
This option can specify up to two WDM
servers. If two are specified, at boot
time the thin client attempts to check-in
to the first server. If it cannot contact
the first server, it tries to check-in to
the second server.
187 WDM server port Optional number. Byte, word, or two-
bytes array.
NOTE: The value of this option
tag, when not embedded in Vendor
Class Specific Information option, is
interpreted in reverse order when
it is sent as 2-bytes example, the
value of 0x0050 was interpreted as
0x5000. This option tag was used
by old ThinOS releases. New ThinOS
releases still accept this option tag
for backward compatibility.
188 Virtual Desktop Broker server Optional string.
190 WDM secure port
Optional number, word or two-bytes
array. Specifies to use HTTPS to
communicate with WDM instead of
HTTP.
192 WDM server port Optional number, word or two-bytes
array.
NOTE: The value of this option tag
represents the same information as
option tag 187. The difference is
that ThinOS interprets the value of
this option tag in correct order (for
example, the value of 0x0050 is
interpreted as0x0050). If the DHCP
server provides both option tag
192 and 187, option tag 192 takes
precedence.
194 WDM FQDN Optional Fully Qualified Domain Name for
the WDM.
