etherconf or ifupdown problem with subnets
I have run across an odd problem when using etherconf in woody to
configure IP addresses statically on a 128 number subnet.
I have a subnet which goes from 184.108.40.206 to 220.127.116.11
When I use etherconf I tell give the mask as 255.255.255.128 but etherconf
does not ask for a broadcast address, nor does it put one in
when the interface is brought up by /sbin/ifup, the broadcast address is
incorrectly set to 18.104.22.168
This causes some huge problems on my network and I have had to remove
etherconf and just edit the /etc/network/interfaces by hand.
BTW, if the netmask is 255.255.255.0 all works perfectly!
I don't know if I should report this as a bug to etherconf or ifupdown, or
even ifconfig. In the first case, it would be good to have a "broadcast"
line in /etc/network/interfaces but that might just be masking a problem
in ifupdown's calculation of a broadcast address from the netmask. Or
perhaps it is a problem in ifconfig. The final possibility is that I am
making a stupid mistake.
