How to set up Alpine as a wireless router
Pi Zero W Wireless Router
This is a page to describe building a Wireless Access Point with two wired ethernet ports for building a home router that connects to the internet with one wired port, and internal Lan with the second wired port and the on-board WiFi.
The intent is to provide this:
|<-->eth1 <-->| Internet <--> eth0 <-->FireWall<-->br0 Internal<--> ssh,bind,dhcp, with ssh reverse ssh connections. |<-->wlan0<-->|
I generally run Debian and when forced by Red Hot Irons, Red Hat. This is my first foray into Alpine. So far I am very impressed. I mirrored the 3.12 armhf repos so I had things local when I needed them. Word to the wise. That is 13G of apk files.
One *really* nice feature of Alpine is apk, the yum/apt replacement:
- It is simple, short, and to the point.
- The same tool provides *repo* level dependency reporting!
- Install of single packages without repo signing (I never did get the signing correct).
- Find a microsd (or HDD) you can wipe. We will assume it is /dev/sdc.
- make a 256M fat16/fat23 partition (sudo mkfs.vfat -n ALPBOOT /dev/sdc1)
- the rest of the device can be ext2 (ext3/4 on HDD) (sudo mke2fs -m1 -L alext3 /dev/sdc2).
- untar the alpine-rpi-3.12.3-armhf.tar.gz and copy all files to the fat16/32 partition 16 is good for up 2 2G.
- Create and index and check dependencies on a list of apk files: apk index -o APKINDEX.unsigned.tar.gz *.apk
- Install a package: apk add iw OR apk add /path/to/iw-5.4-r0.apk
- remove a package: apk del iw
- repositories are in: /etc/apk/repositories
