chmod 660 /dev/kmem
NEVER NEVER give world read to kmem!
Oh yeah. Right. That was silly of Robert to write, and me to
propagate. Anyway, it really ought to appear in the /proc/net filesystem.
Dummy devices do all ipalias can do btw 8). I may well add ipalias as a compile
option some point in the future though
Yes, they can, at the cost of more setup. You have to establish a
route to them, and you also have to set up proxy arp. IPAlias just
works. No muss, no fuss, no bother. And it likely takes more kernel
memory anyway.
