Summary: MS DHCP Server returns SI server IP as hex
Initial Comment:
At boot time the client requests an IP address from
a MS Win2000 DHCP server. The DHCP server
complies and sends an IP address. The DHCP server
also sends the option-140 to pass the SI server IP
address to the client. The SI server IP address
passed to the client is sent as a hex not decimal.
Is there any to make a more intelligent client that
recognizes a hex IP address and converts it to
decimal so that the install can proceed?
The IP address of the SI server is 192.168.168.15
and the client receives the address c0:a8:a8:f
from the DHCP server. Attached is a poor screen
shot taken with a digital camera of what is
happening. I can probably do better if it is needed
to help debug the problem.

it seems that this isn't necessary - a windows server can be
configured to do the right thing.
Randy - can you elaborate on how to do this? i'll add it to
the faq.

Randy: here's some other changes i made, fyi.
i haven't actually added the code to do the conversions for
specific IPs yet, but you would just need to do something like:
IMAGESERVER=$(dehex_ip $IMAGESERVER)

well, the big problems w/ my script are that we don't have
tr, cut,
or bc in the ramdisk.
ok - i can live without cut, but dunno how to get along w/o
bc or tr.
adding full blown bc + tr affects the initrd.img size like so:
base = 532349
base + busybox tr = 533255
base + busybox tr + bc = 562891
base + busybox tr + bc (built w/ -Os) = 560311
we're looking at an additional 27KB.
here's an updated snippet, as a function (tested in busybox
shell)
dehex_ip() {
local hex dec myip="" decimal=""
if echo "$1" | grep -q ":"; then
for hex in $(echo $1 | sed 's/:/ /g' | tr [a-z]
[A-Z]); do
dec=$(echo -e "obase=10\nibase=16\n${hex}" | bc)
myip="${myip}${decimal}${dec}"
decimal="."
done
else
myip=$1
fi
echo "$myip"
}

here's some shell that'll do this:
#!/bin/sh
IP="c0:a8:a8:f"
MYIP=""
if echo "$IP" | grep -q ":"; then
decimal=""
for i in $(seq 1 4); do
hex=$(echo $IP | cut -d ":" -f $i | tr [a-z] [A-Z])
dec=$(echo -e "obase=10\nibase=16\n${hex}" | bc)
MYIP="${MYIP}${decimal}${dec}"
decimal="."
done
else
MYIP=$IP
fi
echo MYIP is $MYIP
