Bootp Server Configuration

Bootp Server Setup on an HP or Sun System

The probe automatically broadcasts Bootp requestswhen its IP address is

0.0.0.0 (the default). The probe broadcasts Bootp requests to signal its need to be configured.

7.For HP-UX systems: Log in as root, then use SAM to follow the instructions presented on the screen.

For HP-UX 9.x, choose:

Networking/Communications -> Service:Enable/Disable

For HP-UX 10.x and 11.x, choose:

Networking and Communications -> Network Services

If the last screen presented in Step 7 displays bootp server enabled, (for either HP-UX 9.x, HP-UX 10.x, or HP-UX 11.x) then your machine is already set up as a bootp server.

8.Edit the /etc/bootptab file to configure the probe and add descriptive comments to the file for reference. Refer to “Configuring the Bootptab File” on page 65, the bootpd(1M) man page or the HP ARPA Services manual for more information on configuring the /etc/bootptab file.

9.Use tail -fto check the system log file to ensure that the Bootp server responded correctly to the Bootp request. The log file is /var/adm/ messages (Solaris), /usr/adm/syslog (HP-UX 9.x), or /usr/ adm/syslog/syslog.log (HP-UX 10.x and 11.x).

10.If you are using HP OpenView, you can verify that LanProbe has been assigned the correct IP address and shows up on the management station map as a network analyzer. The discovery process that places LanProbe in the management station map can take several minutes to complete.

You may be able to decrease the required time for discovery of LanProbe by pinging it continuously from your Agilent NetMetrix management station. You can also ping LanProbe to verify that it responds to the new IP address.
