Hallo, Pratik,

Du meintest am 22.09.11:

Just an example:

Part of "/etc/dnsmasq.conf":


Script "/root/bin/clientname":

#! /bin/bash
# meldet den Client-Name fuer dnsmasq
# wird in der "dnsmasq"-Konfiguration von "dhcp-script" aufgerufen


export LC_ALL=C

echo -e "${2}\t${3}\t${DNSMASQ_SUPPLIED_HOSTNAME}\t"$(date +%F\ %X) >> $Log

# -------------------------------------------------------------

That script has another purpose than you want, but you may see how to  
use the dnsmasq variables.

You can see more details via

        man dnsmasq

under "-6 --dhcp-script"

The meaning of "${1}" to "${4}" is explained under "arguments" in this  
p.e.: "${2}" contains the MAC address.

Viele Gruesse!
