Unknown IP Address

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

zChange 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.

zUse 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.

zPress ^r to redraw the screen.

INIT: Error in terminal file <filename>

zThis 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>

zYou 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.

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

zYou 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.

zThe 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.

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

zCheck 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:

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

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

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

zReset or restart the DHCP server.
