Setting netmask

[Pertti Lehtinen]

We also findout that atleast systems running OS4.0.1 very likely set their
subnetmasks according broadcasts.

It seems that if someone sends different mask than host has, host changes
its mask, which causes nearly all network traffic to stop from/to that
host.

Very nasty this is with numerous workstations, because you aren't anymore
able to log in.  So all workstations have to be rebooted.

So, be careful, no strange broadcasts, please.
