177: Getting Pi on my Wifi

Published 9 years, 2 months ago

This week on BSDNow, we’ve got Wifi galore, a new iocage and some RPi3 news and guides to share. Stay tuned for your place to B...SD!

“OpenBSD as WiFi access points look set to be making a comeback in the near future”
“Stefan Sperling added 802.11n hostap mode, with full support initially for the Atheros chips supported by the athn(4) driver.”
“Hostap performance is not perfect yet but should be no worse than 11a/b/g modes in the same environment.”
“For Linux clients a fix for WME params is needed which I also posted to tech@”
“This diff does not modify the known-broken and disabled ar9003 code, apart from making sure it still builds.”
“I'm looking for both tests and OKs.”
There has also been a flurry of work in FreeBSD on the ath10k driver, which supports 802.11ac

We’ve hinted at the new things happening behind the scenes with iocage, and this last week the code has made its first public debut.
So what’s changed you may ask. The biggest is that iocage has undergone a complete overhaul, moving from its original shell-base to python.
The story behind that is that the author (Brandon) works at iXsystems, and the plan is to move away from the legacy warden-based jail management which was also shell-based.
This new python re-write will allow it to integrate into FreeNAS (and other projects) better by exposing an API for all jail management tasks. Thats right, no more ugly CLI output parsing just to wrangle jail options either at creation or runtime.
But what about users who just run iocage manually from the CLI? No worries, the new iocage is almost identical to the original CLI usage, making the switch over very simple.
Just to re-cap, lets look at the new features list:

“FEATURES:

Ease of use
Rapid jail creation within seconds
Automatic package installation
Virtual networking stacks (vnet)
Shared IP based jails (non vnet)
Transparent ZFS snapshot management
Export and import “
The new iocage is available now via ports and packages under sysutils/py-iocage, give it a spin and be sure to report issues back to the developer(s). ***

“DHT-11 is a very cheap temperature/humidity sensor which is commonly used in the IoT devices. It is not very accurate, so for the accurate measurement i would recommend to use DHT21 instead. Anyway, i had DHT-11 in my tool box, so decided to start with it. DHT-11 using very simple 1 wire protocol – host is turning on chip by
