Hi all.  I just set up redhat 4.0 i386, and am having routing problems.
I am simply trying to add a route to the loopback device, and not even
that will work now.

# ifconfig lo 127.0.0.0.1
# ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Bcast:127.255.255.255  Mask:255.0.0.0
          UP BROADCAST LOOPBACK RUNNING  MTU:3584  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0
          TX packets:0 errors:0 dropped:0 overruns:0

# route add -net 127.0.0.0 netmask 255.255.255.0
route: netmask doesn't match route address
Usage: route [-nNvee] [-FC] [Address_families]  List kernel routing tables
       route {-V|--version}                Display command version and exit.
   . . .

This doesn't make sense to me, and I don't know what to do next.  If I
type:

# route add 127.0.0.1

Then I get:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref  Use  Iface
localhost       *               255.255.255.255 UH    0      0        0 lo

But that is not done correctly.  And adding an eth0 never worked...  My
3c509 module is installed, and this is basically otherwise a stock 4.0
i386 install using 2.0.18.

I have gone thru the netcfg and just can't figure this out.
Can anyone shed some light on what might be going on here?

Thanks,
Dave Wreski
