I'm trying to turn of the broadcast flag for a network card. But I
can't, why??

I have two network-cards in the machine and an application (rwhod) that
wants to send it's messages out on every interface that can broadcast. But
never want to broadcast anything on this interface so why not turn it
of? If I could that is..

This is what happens:

$ ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 00:50:BA:6E:76:63  
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:143190 errors:0 dropped:194 overruns:0 frame:0
          TX packets:143584 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          Interrupt:9 Base address:0xe400 

$ ifconfig eth1 -broadcast
$ ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 00:50:BA:6E:76:63  
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:143228 errors:0 dropped:194 overruns:0 frame:0
          TX packets:143622 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          Interrupt:9 Base address:0xe400 

As you can see. It still says BROADCAST.

This is on the 2.2.16 kernel and

$ ifconfig -V
net-tools 1.54
ifconfig 1.39 (1999-03-18)
