6.4.4 Setting Up a tftpboot Server
To set up a tftpboot server, on a SunOS 4.1.x system, perform the following
steps:
NOTE: This procedure only has to be done the first
time that the switch is turned on and each
SCP is upgraded. The next time that the soft-
ware is upgraded, put the upgrade file in
/tftpboot.
1. In /etc/inetd.conf, uncomment the last line shown below so that the file
appears as follows:
#
# Tftp service is provided primarily for booting. Most sites
# run this only on machines acting as “boot servers.”
# Since these can be security holes, they are commented out by default.
#
tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd /tftpboot
2. Add the following line to /etc/services:
tftp 69/udp
3. Set up the tftpboot directory with the following command lines:
host: mkdir /tftpboot
host: cp <upgrade-file> /tftpboot
4. At the root level, determine the process number of inetd by entering the
following:
host: ps -aux | grep inetd
Something similar to the following will be displayed:
root 216 0.0 0.0 48 0 ? IW Jan 27 0:14 inetd
where 216 represents the process number of inetd.
5. Enter the following command to make inetd re-read its configuration file:
host: kill -HUP 216
