HP-UX IP Address and Client Management Administrator's Guide HP-UX 11i v2, HP-UX 11i v3
The gateway address (gw=15.19.8.1) is passed back to the client in the bootreply and allows
the client to send a TFTP request to the BOOTP server to get its boot file.
To verify the new /etc/bootptab entry, do the following:
1. Add the ba (broadcast address) tag to the xterm02 entry as follows on the BOOTP server
that contains the client’s boot entry (Server B):
xterm02: ht=ether: ha=08000902CA00:\
ip=15.19.8.39: sm=255.255.248.0:\ gw=15.19.8.1: ds=15.19.8.119: bf=/xterminal ba
The bootreply is not sent directly to xterm02 but broadcasted to ba. This allows the
bootpquery diagnostic tool to intercept any bootreply packets for xterm02.
2. If you can boot the client in standalone mode, run the bootpquery tool on the client to
check how bootpd on the server responds to a request from xterm02. For the example
configuration, you can run the following query (as superuser):
# /usr/sbin/bootpquery 08000902CA00
You can also run bootpquery from another machine running on the same subnet as the
client.
The following output is displayed:
Received BOOTREPLY from hpserver.hp.com (15.4.3.136)
Hardware Address: 08:00:09:02:CA:00
Hardware Type: ethernet
IP Address: 15.19.8.39
Boot file: /xterminal
RFC 1048 Vendor Information: Subnet Mask: 255.255.248.0
Gateway: 15.19.8.1
Domain Name Server: 15.19.8.119
Host Name: xterm02.hp.com
This shows that the BOOTP server responded with information that corresponds to the
client entry in the /etc/bootptab file. You can also conclude that the bootrequest was
correctly relayed to the BOOTP server that contains the client’s boot information.
3. Remove the ba tag entry from the /etc/bootptab file.
Configuring the TFTP Server
Configuring the TFTP server, tftpd, on your system allows remote clients that support TFTP
to access files on your system in a particular location. You can configure tftpd either manually
or by using HP SMH. To manually configure tftpd, you must uncomment the tftp entry in
the /etc/inetd.conf file. If you do not specify the path options for the tftp entry in the
/etc/inetd.conf file, you must create a pseudouser tftp in the /etc/passwd file. For more
information, type man 1M tftpd at the HP-UX prompt.
If you use HP SMH to configure your system as a BOOTP server, your system is automatically
configured as a TFTP server. The following section explains how to manually configure and
verify tftpd.
NOTE: You must log in as a root user to configure the TFTP server.
Procedure for Configuring tftpd
To manually configure tftpd, you can follow either of the following methods:
Method 1
Add the user tftp to the /etc/passwd file.
For example:
tftp:*:510:10:TFTP:/home/tftpdir:/usr/bin/false
