iptohex (convert an ipaddress into hexadecimal)

Script: iptohex

No error checking, just a simple time saver. Converts an ipaddress into hexadecimal suitable for use by tftp tools and pxe booting. The builtin command gethostip does this also, I include the script incase someone finds it useful.

Example:

uphill@surrey[1]: 
iptohex 10.168.192.134
0AA8C086


#!/bin/bash

IPADDR=$1

if [ x${IPADDR}x = xx ]; then
echo "usage: $0 "
exit 1
fi

for octet in `echo $IPADDR |tr '.' ' '`
do
printf "%02X" "$octet"

done
echo
