Troubleshooting 113

Unknown IP Address

When using the function keys on your keyboard, nothing happens or your sessions keep
swapping.

z

Change your

Hotkey Prefix

character. The function keys on the keyboards of some terminals

(like WYSE60) send character sequences which begin with

^a

; unfortunately,

^a

is also the

default

Hotkey Prefix

, which you use to switch between sessions. A valid alternative would be

^b

(hex=02). If you are the system administrator, you can change any user’s

Hotkey Prefix

character.

When using a downloaded terminal definition, you are having problems using arrow keys.

z

Use Ctrl-K, Ctrl-J, Ctrl-H and Ctrl-L for up, down, left and right respectively.

When switching from a session back to the text menus, both screen images are superimposed.

z

Press

^r

to redraw the screen.

INIT: Error in terminal file <filename>

z

This error indicates that you have exceeded the 80 character limit for one or more of the terminal
capabilities defined in the reported file.

INIT: Error on line n in terminal file <filename>

z

You have omitted the

=

sign from the reported line.

Unknown IP Address

You have a Device Server already configured and you do know your password, but have lost,
misconfigured, or don't know the IP address of the Device Server, and you cannot obtain a
login.

z

If the Device Server resides within the local network segment, you can use DeviceManager to
find the Device Server.

z

You can connect directly to the serial port of the Device Server, as explained in

Using a Direct

Connection on page 24

.

DHCP/BOOTP Problems

Messages:

host name too long

or

filename too long.

z

The Device 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 Device 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 Device 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 Device 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.
