DHCP/BOOTP Problems

Terminal Server User Guide

DHCP/BOOTP Problems

Messages: 

host name too long

 or 

filename too long.

z

The Terminal Server can only accept host names of 14 characters or file names of 64 
characters, so verify that you are not attempting to pass a string that is longer than those 
maximums.

DHCP or BOOTP have been set up to configure my 

Terminal Server

, but does not seem to 

have done anything.

z

Check that the server DHCP/BOOTP service is set to on, if not set it to on and reboot.

z

Check that your BOOTP server is configured for your Terminal Server or that your DHCP 
server has an active lease pool (scope) with at least 1 free IP address.

You observe TFTP errors when the 

Terminal Server

 boots, for example:

TFTP: File not found : filename

TFTP: Timed out

This has a number of causes, including:

z

The file names you specified to DHCP/BOOTP do not exist or are in the wrong place.

z

The server for any of the downloadable files in your bootfile has no TFTP server running.

z

Verify that lease data in your DHCP server manager is correct.

z

Reset or restart the DHCP server.

Language Problems

In a customised language, the text strings appear in the wrong place in the Menu, CLI, or 
WebManager.

z

Check the original ASCII text file you used to translate to your customised language. The 
sequence of the line much match exactly (be aware that comments don’t affect line 
sequence, but can affect the actual line that the strings appear on). So, if you strip out all 
comments, if the original file says line 1000 should be string 

none

, then line 1000 (stripped of 

comments) should be the translated version of 

none

. 

Long Reboot Cycle

Rebooting the 

Terminal Server

 takes a long time.

If you are not using DHCP/BOOTP, disable this within the Server Services; otherwise, the 
Terminal Server waits to timeout for a request to DHCP/BOOTP.
