yes, it works with gawk. what is the difference between these tools?

there is one problem actually left:

the mac address has 6 sections, seperated by colons. that is: the first two digits have to be discarded. could you change the code a little, so I can keep only the following 12 digits. thanks!

Code:
BEGIN {
  macLength="12"
}
{
   mac=( length($1) > macLength ) ? substr($1, length($1) - macLength +1) : $1
   gsub("..", "&:",mac)
   gsub(":$", "",mac)

   printf("host {\nhardware ethernet %s;\nfixed-address %s;\n}\n", mac, $3)
}
