[arch-general] which package provides ifup & ifdown command ?

[Jeff Horelick]

As Sven-Hendrik said, you need to use ifconfig $interface up and ifconfig
$interface down. If you really need ifup and ifdown, put this in your
.bashrc:

alias 'ifup eth0'='ifconfig eth0 up'
alias 'ifdown eth0'='ifconfig eth0 down"

It's likely that you could replace hardcoding eth0 with using something like
$2, but it's 4AM and i'm too lazy to write up a example for that.
