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:
