Setting Up a UNIX Boot Server

# This file contains the default specification for the boot
# image file to be used by all ANs.
# "general" contains information that is common to all ANs
# that need to boot via BOOTP. You can use any word in place
# of "general."
general:\
# "hd" specifies that /$HOME/.builder_dir/rel900/an is the
# directory on the workstation where the boot files are
# located. By default, the Image Builder writes its files to
# this directory. If you are using a router software version
# later than 8.00, add the associated three digits to the end
# of the "rel" directory name. If you moved the files to
# another directory, specify that directory.
:hd=/$HOME/.builder_dir/rel812/an:\
# "bf" specifies that the name of the boot image kernel file
# is krnl_an.exe.
:bf=krnl_an.exe:\
# "bs" indicates the size of the boot file. If you specify
# "auto" as the size, the BOOTP server calculates the size of
# the file for each BOOTP request.
:bs=auto:\
# "vm" indicates that the BOOTP server should always reply in
# a manner compliant with RFC 1048. You must enter rfc1048
# for this tag so that the AN can understand the BOOTP
# responses it receives.
:vm=rfc1048:
# This line marks the beginning of the active definition for
# the AN we are naming "AN.Boston."
AN.Boston:\
# "ip" indicates the IP address of the AN.
:ip=192.32.5.2:\
# "T130" indicates the size of the AN’s configuration file in
# 512-byte blocks. Always use 0x0004.
:T130=0x0004:\
# "T129" indicates the pathname of the configuration file
# for the AN.
:T129="/usr1/cfg/AN_Bost.cfg":\
# "tc" indicates that the "general" definition contains more
# information that applies to BOOTP transmissions to
# "AN.Boston."
:tc=general:
# This is the active definition for the AN we are naming
# "AN.Chicago."
AN.Chicago:\
:ip=10.0.0.4:\
:T130=0x0004:\
