ifconfig network resolution (Re: pointers to material for using netbook's wireless as access point)

Show all headers | View raw

Experimenting from the command line, I find myself puzzled about the
arguments for ifconfig.

Reading the manual, it would appear that the arguments for ifconfig
should be something like this:

    ifconfig eth0 netmask 255.255.255.224 netmask 255.255.255.224
broadcast 10.19.23.223 10.19.23.94

But the command returns with

SIOCSIFNETMASK: Can't allocate this address.
SIOCSIFBRDADDR: Can't allocate this address.

If I repeat the command, it gives no errors, but the netmask and
broadcast address end up full class A (255.0.0.0 and 10.255.255.255).

Anyone have an idea what's happening?

One of these days I'll get someone to pay me
to design a language that combines the best of Forth and C.
Then I'll be able to leap wide instruction sets with a single #ifdef,
run faster than a speeding infinite loop with a #define,
and stop all integer size bugs with a bare cast.

More of my delusions:
