Turris - OpenWRT and guest access

In my previous blog post I described the way how to configure the Turris router for my home network. I decided to extend the configuration and create the Guest WiFi for other people who want's to access the "Internet". In my solution I'm using the nodogsplash captive portal solution which offers simple way to provide restricted access to an Internet connection. Here is the extended network diagram:

Turris - OpenWRT and thermometers

I would like to put here some notes about the thermometers in OpenWrt and Turris.

Turris internal thermometers

Turris has it's own thermometers which are monitoring the temperature of CPU and board. The how-to expects the previous lighttpd configuration described in my previous post. Here is the way how you can create graps wrom the data using RRDtool.

Turris - OpenWrt configuration

You can find out some details about Turris wifi router, lot of photos and some command outputs in my previous blog post. Now I would like to describe the way how I configured it according the network diagram:

I will also need my own web pages, transmission torrent client, microsd card, Dynamic DNS and extend the luci interface to add some more stats + graphs. Here are the steps how I did it. There is no guarantee it will work for another Turris router.

Turris - The Open Enterprise Wi-Fi Router

Few months ago I joined the Turris project (turris.cz) which is a not-for-profit research project of CZ.NIC. I don't want to describe the details of the project, because you can find it on it's web page. In short the company standing behind the project take care about the Internet security and their idea was to measure number of attacks / suspicious traffic by giving the wifi routers to the participants.
The wifi router was designed by the company and it's quite powerfull machine costs 600$. In the first "round" some project members got the wifi router for free so I would like to share here the details bout it, because it's open hardware/software platform.

TP-Link TL-WR1043ND and OpenWrt 12.09 with two SSIDs (MultiSSID) - private and guest

I decided to change my home network to match the following "network diagram":

The core part of the design is TP-Link TL-WR1043ND wifi router running OpenWrt with small 16GB USB stick [/dev/sda1] containing ext3 partition with OpenWrt configuration + swap.

There are also 16GB USB stick and 2 thermometers connected using USB <-> Serial connector (bought on eBay):

I'm going to use the last stable version of the OpenWrt firmware: openwrt-ar71xx-generic-tl-wr1043nd-v1-squashfs-sysupgrade.bin

Upgrade the firmware and remove the old configuration:

rm -r /tmp/opkg-lists/
sysctl -w vm.drop_caches=1
sysupgrade -v -n http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/openwrt-ar71xx-generic-tl-wr1043nd-v1-squashfs-sysupgrade.bin

Here are the notes how way how I configured it.

Another OpenWrt configuration

I would like to describe another OpenWrt configuration. It's going to be just few examples how to configure latest available OpenWrt firmware Backfire 10.03.1.

I'm going to use TP-Link TL-WR1043ND wifi router with small 64MB USB stick [/dev/sda1] containing ext2 partition. I plan to have some stats on the USB stick and simple html pages as well.

OpenWrt (Backfire 10.03) and TL-WR1043ND

I would like to describe another OpenWrt configuration. It's going to be just few examples how to configure latest available OpenWrt firmware Backfire 10.03.1.

I'm going to use TP-Link TL-WR1043ND wifi router with small 64MB USB stick [/dev/sda1] containing ext2 partition. I plan to have some stats on the USB stick and simple html pages as well.

OpenWrt with Transmission, Samba and vsftpd

My brother asked me to customize firmware in his WiFi router TP-Link TL-WR1043ND. He wants to use if for downloading torrents and sharing them using smb and ftp protocols.

I have good experiences with OpenWrt, which is really good in customization and suits well for this purpose. Nowadays you there are few torrent clients in OpenWrt distribution, but I choose transmission and for ftp daemon vsftpd.
