Netgear WGT634U-based Network Stumbler

The Jason McArthur Version

As early as the summer or early autumn of 2005, JasonMcArthur began working on a Netgear WGT634U-based stumbler device, based on OpenWgt and a 2.4.20 kernel.

  • [Need OpenWgt-based stumbler construction instructions here]

The Russell Senior Version

In early March of 2006, RussellSenior began sponging off of JasonMcArthur's work and assistance. Eventually, because he didn't have access to JasonMcArthur's build environment, and because he was seeing some problems that he didn't understand and needed to fiddle with, he began diverging from JasonMcArthur's image, and began playing with an OpenWrt-derived stumbler instead, principally because he understood how to build packages using its buildroot environment.

This is a description of how RussellSenior goes about building a stumbler device based on the NetgearWgt643u and OpenWrt. This is experimental software. Follow these instructions at your own risk.

Hardware

  • Netgear WGT634U
  • USB2 hub
  • USB storage device
  • USB GPS device (such as the GlobalSat BU-353)

  • 3.3V serial console cable for WGT634U
  • random, compact USB device (used as an enable-key)

Building OpenWrt Software

Currently, I am using the kamikaze svn tree. This description is based on the already obsolete r5952.

cd /src/openwrt
svn co https://svn.openwrt.org/openwrt/trunk
svn co https://svn.openwrt.org/openwrt/packages 
cd /src/openwrt/trunk
ln -s /src_archive/openwrt/dl .  # an existing archive of downloaded packages
cd /src/openwrt/trunk/package 
for i in $(find ../../packages -type d | grep -v .svn | awk -F/ 'NF==5') ; do echo $i ; ln -s $i $(echo $i | awk -F/ '{ print $5 }') ; done

# add package infrastructure for an older version of gpsd (v2.9)
mkdir /src/openwrt/trunk/package/gpsd-old
cd /src/openwrt/trunk/package/gpsd-old
wget http://www.personaltelco.net/~russell/gpsd-old-makefile
mv gpsd-old-makefile Makefile

cd /src/openwrt/trunk
make menuconfig
make

In the menuconfig, I set the Target System to (Broadcom BCM947xx/953xx [2.6]), and for kicks I also "Select all packages by default" and enable a few things (which I am currently forgetting) that don't automatically get configured in. Often, you will find packages that won't build for some reason or another. In those cases, open a ticket, deconfigure the package in menuconfig and try again. Run make alone to see abbreviated messages, or make V=99 to get lots of information. The configuration I used for r5952 can be found [http://www.personaltelco.net/~russell/kamikaze/config-r5952 here].

When the build is complete, the resulting files will be found thusly:

  • /src/openwrt/trunk/bin contains the flashable images

  • /src/openwrt/trunk/bin/packages contains the .ipk files

Additionally, as of my recent attempts, the Packages file that is needed for the ipkg utility to function properly later on is apparently not constructed (maybe I missed it), but I developed a script that does it for me:

TOPDIR="/src/openwrt/trunk"

CTRLDIR="${TOPDIR}/build_mipsel"
PKGSDIR="${TOPDIR}/bin/packages"
PKGSFIL="${PKGSDIR}/Packages"

rm -f ${PKGSFIL}

for i in $(find ${CTRLDIR} -name 'control' | grep CONTROL) ; 
  do echo $i ; 
  PACKAGE=$(grep ^Package: $i | cut -d' ' -f2) ; 
  VERSION=$(grep ^Version: $i | cut -d' ' -f2) ; 
  ARCH=$(grep ^Architecture: $i | cut -d' ' -f2) ; 
  FILENAME="${PACKAGE}_${VERSION}_${ARCH}.ipk" ;
  IPKG="${PKGSDIR}/${FILENAME}"
  if [ -f ${IPKG} ] ; then
      SIZE=$(wc -c ${IPKG} | cut -d' ' -f1) ; 
      MD5=$(md5sum ${IPKG} | cut -d' ' -f1) ; 
      cat $i >> ${PKGSFIL} ; 
      echo "Filename: ${FILENAME}" >> ${PKGSFIL} ; 
      echo "Size: ${SIZE}" >> ${PKGSFIL} ; 
      echo "MD5Sum: ${MD5}" >> ${PKGSFIL} ; 
      echo "" >> ${PKGSFIL} ; 
  else
      echo "${FILENAME} NOT FOUND!"
  fi
done

Now, you can copy the ipkg repository somewhere wget'able, e.g.:

rsync -v -a -H /src/openwrt/trunk/bin/packages/ donk.personaltelco.net:public_html/kamikaze/r5952/

Checking out the WGT634U

If this is a new device, it is probably a good idea to check it out on the stock firmware first to make sure it functions.

  • apply power
  • use another computer to associate over the wireless

The Flash Environment

There is more than one way to flash the newly-built image onto the WGT634U.

CFE TFTP Flash-From-Console Method

This is the method I tend to use. For this, you will need a TFTP server and a serial console cable. On my debian/unstable box, I use the tftpd-hpa package.

  • copy the image file to the TFTP server directory.
    cp /src/openwrt/trunk/bin/openwrt-wgt634u-2.6-jffs2.bin /var/lib/tftpboot/wgt634u/openwrt-wgt634u-2.6-jffs2-r5952.bin
  • open the WGT634U case by removing 4 screws from the bottom. These are either ordinary phillips (often seen on the refurbs) or T-8 torx screws.
  • connect the serial console to the WGT634U
  • connect a LAN network cable to the WAN port (nearest the USB port)
  • while holding Ctrl-C on the serial console, apply power:

  • Configure the network. This is easiest if there is a DHCP server on the network:
    CFE> ifconfig eth0 -auto
    Device eth0:  hwaddr 00-0F-B5-97-29-39, ipaddr 192.168.0.145, mask 255.255.255.0
            gateway 192.168.0.1, nameserver 192.168.0.1, domain personaltelco.net
    *** command status = 0
  • You can blank out the flash using specially prepared wipe images. Note that the file size that you can TFTP is limited so this must be done in two steps. This might in fact be unnecessary, but it works for me:
    CFE> flash -noheader 192.168.0.5:wgt634u/wipe-1.img flash0.os
    CFE> flash -noheader -offset=3932160 192.168.0.5:wgt634u/wipe-2.img flash0.os
  • Now, flash the image you want to use and reboot:
    CFE> flash -noheader 192.168.0.5:wgt634u/openwrt-wgt634u-2.6-jffs2-r5952.bin flash0.os
    CFE> reboot

Configuration

  • To get a console prompt, wait until the bootup has finished, and press enter to wake up a shell.
  • You can configure your ethernet network as follows (assuming you have a DHCP server available):
    udhcpc -i eth0
  • In order to take advantage of your kamikaze ipkg's, you first need to modify /etc/ipkg.conf:
    src snapshots http://www.personaltelco.net/~russell/kamikaze/r5952
    #src snapshots http://openwrt.org/downloads/snapshots/brcm-2.6/packages
    dest root /
    dest ram /tmp
  • To update your WGT634U using this package archive:
    ipkg update
  • Now, start adding packages:
    ipkg install kmod-usb2
    ipkg install kmod-usb-storage
    ipkg install kmod-usb-serial-pl2303
    ipkg install gpsd-old
    ipkg install kmod-fs-vfat
    ipkg install kmod-nls-cp437
    ipkg install kmod-nls-iso8859-1
  • Install the statically-linked MIPS binary of kismet from [http://www.kismetwireless.net/code/kismet-2006-04-R1-wrt54.tar.gz here] and copy it somewhere useful:

    cd /tmp
    wget http://www.kismetwireless.net/code/kismet-2006-04-R1-wrt54.tar.gz
    tar xzvf kismet-2006-04-R1-wrt54.tar.gz
    cp kismet-2006-04-R1-wrt54/kismet_server /usr/bin/
  • add an /etc/kismet.conf. Here's the one I am using, derived from one from JasonMcArthur:

    # Kismet config file

    # config was getting way too crowded and cryptic.  We want functionality,
    # not continually reading --help!

    # Sources are defined as:
    # source=cardtype,interface,name[,initialchannel]
    # Card types and required drivers are listed in the README.
    # The initial channel is optional, if hopping is not enabled it can be used
    # to set the channel the interface listens on.
    # YOU MUST CHANGE THIS TO BE THE SOURCE YOU WANT TO USE
    # source=wrt54g,eth1,wireless
    # For v1 hardware uncomment this:
    # source=wrt54g,eth2,wireless
    source=madwifi_g,wifi0,wgt634u
    
    # Comma-separated list of sources to enable.  This is only needed if you defined
    # multiple sources and only want to enable some of them.  By default, all defined
    # sources are enabled.
    # For example:
    # enablesources=prismsource,ciscosource
    
    # Do we channelhop?
    channelhop=true
    
    # How many channels per second do we hop?  (1-10)
    channelvelocity=5
    
    # By setting the dwell time for channel hopping we override the channelvelocity
    # setting above and dwell on each channel for the given number of seconds.
    #channeldwell=10
    
    # Do we split channels between cards on the same spectrum?  This means if 
    # multiple 802.11b capture sources are defined, they will be offset to cover
    # the most possible spectrum at a given time.  This also controls splitting
    # fine-tuned sourcechannels lines which cover multiple interfaces (see below)
    channelsplit=true
    
    # Basic channel hopping control:
    # These define the channels the cards hop through for various frequency ranges
    # supported by Kismet.   More finegrain control is available via the 
    # "sourcechannels" configuration option.
    # 
    # Don't change the IEEE80211<x> identifiers or channel hopping won't work.
    
    # Users outside the US might want to use this list:
    # defaultchannels=IEEE80211b:1,7,13,2,8,3,14,9,4,10,5,11,6,12
    defaultchannels=IEEE80211b:1,6,11,2,7,3,8,4,9,5,10
    
    # 802.11g uses the same channels as 802.11b...
    defaultchannels=IEEE80211g:1,6,11,2,7,3,8,4,9,5,10
    
    # 802.11a channels are non-overlapping so sequential is fine.  You may want to
    # adjust the list depending on the channels your card actually supports.
    # defaultchannels=IEEE80211a:36,40,44,48,52,56,60,64,100,104,108,112,116,120,124,128,132,136,140,149,153,157,161,184,188,192,196,200,204,208,212,216

    # Combo cards like Atheros use both 'a' and 'b/g' channels.  Of course, you
    # can also explicitly override a given source.  You can use the script

    defaultchannels=IEEE80211ab:1,6,11,2,7,3,8,4,9,5,10,36,40,44,48,52,56,60,64
    
    # Fine-tuning channel hopping control:
    # The sourcechannels option can be used to set the channel hopping for 
    # specific interfaces, and to control what interfaces share a list of 
    # channels for split hopping.  This can also be used to easily lock
    # one card on a single channel while hopping with other cards.
    # Any card without a sourcechannel definition will use the standard hopping
    # list.
    # sourcechannels=sourcename[,sourcename]:ch1,ch2,ch3,...chN
    
    # ie, for us channels on the source 'prism2source' (same as normal channel

Adding Sound

For this, you need a usb-audio device and some additional software:

  • I am using the Turtle Beach Audio Advantage Micro device (CompUSA, roughly $25)
  • Install sound packages:
    ipkg install kmod-alsa
    ipkg install kmod-soundcore
    ipkg install madplay
  • I used a combination of festival and toolame to create mp3's for madplay:
    echo "string" | text2wave - > string.wav
    toolame string.wav string.mp3
  • Create a wrapper for madplay (to enclose the options). The soundopts feature in the kismet.conf file is broken because of the way they are concatenated in the call to execve().
    cat > /usr/bin/play <<EOF
    #!/bin/sh
    
    /usr/bin/madplay -Q -a -10 --no-tty-control $@
    EOF
    chmod 755 /usr/bin/play
  • Insert the following into /etc/kismet.conf
    # Do we use sound?
