Getting Started 2–5
Updating the Debug Monitor Firmware
4. Modify the /etc/bootptab file to specify the Ethernet hardware address of
the motherboard and the IP address assigned to that node. Contact your network
administrator to obtain an IP address. Refer to the literature supplied with your
Ethernet card to obtain information about the hardware address. If the hardware
address is accessible through software, you can use the einit command to display
it. For example, the following lines modify this file for the EB64:
remote_system_name0 :ht=ethernet:ha=BA9876543210:ip=16.123.45.67:\
:hd=
/directory1 :bf= filename :vm=auto:
BOOTP checks this file to see if it has changed each time it receives a request. If
it has changed, the new file is read. The directory and filename are the defaults
for the netload and netboot commands. If no argument is specified with either
command, the file loaded is /directory1/filename.
Verify the BOOTP Server
To verify that the BOOTP server has been set up properly, you can look at the
daemon.log file. This file shows directories accessed for the netload or netboot
commands.
# tail -f /var/adm/sylog.dated/ dated_dir /daemon.log
The following example displays a boot request from an example daemon log file:
May 5 10:40:28 eval bootpd[328]:request from hardware address BA9876543210
May 5 10:40:28 eval bootpd[328]:found: eb64 (BA9876543210) at (16.123.45.67)
May 5 10:40:28 eval bootpd[328]:file /users/eval/boot/size.eb64 not found
May 5 10:40:28 eval bootpd[328]:vendor magic field is 0.0.0.0
May 5 10:40:28 eval bootpd[328]:sending RFC1048-style reply
You can refer to the DIGITAL UNIX man pages for more information about bootp,
bootpd, tftp, tftpd, inet, inetd, and init.
2.3.4.3 Setting Up the Host System As a Ladebug Client
The Debug Monitor supports remote debugging for DIGITAL UNIX host systems
with Ladebug. The Ladebug software does not accept numeric internet addresses.
You can give your motherboard an internet name in the /etc/hosts file. In the
/etc/hosts file, the format is the internet protocol (IP) address followed by the
host system name. For example:
12.345.67.89 remote_system_name0
2.4 Updating the Debug Monitor Firmware
Depending on the type of motherboard, the firmware is stored in either a flash ROM
or a UVPROM.
