Dhcp Troubleshooting; Bootp Troubleshooting - Black Box 16-Port Rackmount 10/100 Installation Manual

11.2 DHCP Troubleshooting

Area to Check
DHCP is enabled on the Termi-
nal Server
Make sure the DHCP server is
operational.
The Terminal Server gets its IP
address from the DHCP server

11.3 BOOTP Troubleshooting

If the BOOTP request is failing and you have configured your host to respond to the
request, check these areas:
Area to Check
BOOTP is in your system's
/etc/services file
The Terminal Server is in the
loadhost's
/etc/hosts file
The download file is in the cor-
rect directory and is world-read-
able
The Terminal Server and host are
in the same IP network
Table 11-2: DHCP Troubleshooting
Explanation
Use the Set Server DHCP Enabled command.
If you manually enter an IP address, DHCP is automatically
disabled.
Check to see that the DHCP server is on and is functioning
correctly.
Refer to the DHCP Manager on your DHCP server for
information about addresses in use. If the DHCP server
doesn't list your Terminal Server IP address, there may be a
problem.
Table 11-3: BOOTP Troubleshooting
Explanation
BOOTP must be an uncommented line in /etc/services.
The Terminal Server must be in this file for the host to
answer a BOOTP or TFTP request.
The download file must be in the correct directory and
world-readable. Specify the complete pathname for the
download file in the BOOTP configuration file, or add a
default pathname to the download filename.
Some hosts will not allow BOOTP replies across IP net-
works. Either use a host running a different operating sys-
tem or put the Terminal Server in the same IP network as
the host.
