After spending a couple of hours trying to get a new Aviion workstation
connected to the net, I have discovered a bug in the tcpipparams script.
In the script a shell-function called generate_minimum_netmask uses awk
to calculate the netmask: (from my memory)

  echo $1 | awk 'BEGIN {
	if ( $1 < 127 ).....

On my machine, awk terminates with a cryptic error message, and the
script continues with a wrong result.

Why is the BEGIN necessary? It's not used in any of the other functions.
If I delete the BEGIN, everything works fine.

Is it time for comp.os.dgux?
