Penned by Jan Stary on 20121017 10:46.55, we have:
| This is current/i386 on an IBM Thinkpad T40.
|
| It comes with an ipw(4) wifi interface, which works fine. Anyway,
| the ipw(4) seems to be one of the substantial battery eaters. So
| I would like to not use the interface when running on battery
| and not actually using a wifi connection.
|
| Running 'ifconfig ipw0 down' seems to do that: the antenna icon led
| switches off, and time left (as reported by apm) starts increasing.
| (What would be a more rigorous way to see that the battery is actually
| running off more slowly now, others being equal? The machine doesn't
| have any sensors, as reported by 'sysctl hw').
|
| I would like to let that happen automatically, if only because sometimes
| I forget to do that, and drain the battery considerably faster.
| What is the preffered way to do that? Is ifstated(8) the way?
|
| istated(8) is monitoring the 'interface link state'.
| Is 'no network' recognizable as an interface link state?
| What I would like to recognize with ipw0 is what
| 'no carrier' would be for an ethernet interface:
| is that a good analogy? 'no network' just means
| the interface is not associated to any network,
| not that there isn't a nework around, right?
|
| Now I tend to put
|
| ifconfig ipw0 | grep 'no network' > /dev/null && ifconfig ipw0 down
|
| into the root's crontab but that seems a bit crude.
|
| Jan
A slightly less crude way would be to put this there:
ifconfig egress | grep "^ipw0" > /dev/null && { apm | grep 'A/C adapter
state: connected' || ifconfig ipw0 down; }
because if 'egress' is not on ipw0 you're not using wireless,
and if the A/C adapter state is not connected, you're on battery.
Just sayin' ;-)
