GuruPlug Debian¶

GuruPlug Server Plus Debian GNU/Linux Notes

Wireless¶

Installation¶

we need the uap8xxx.ko kernel module, and the uaputl setup utility (the latter shipped with the GuruPlug as /usr/bin/uaputl)
- uses /lib/firmware/mrvl/helper_sd.bin, /lib/firmware/mrvl/sd8688_ap.bin (shipped with the GuruPlug)
disable wireless client mode modules libertas_sdio.ko and libertas.ko
- uses sd8688.bin, sd8688_helper.bin (found in /root/firmware; also in Debian package libertas-firmware)
remove or disable call to /root/init_setup.sh from /etc/rc.local

Download¶

guruplug-wl-1691.sh – the script (do not forget to chmod +x ...) with instructions (in the script)

Issues¶

PlugForum:1648 – wireless access point module and user space setup utility (uaputl); modinfo uap8xxx.ko says «Marvell» and «GPL».. but where’s the source code for the uaputl?

Cleanup¶

/etc/ifplugd/ifplugd.action – cleaned by dist-upgrade to squeeze
removed usbmount, udhcpd, dbus and other stuff
created new ssh keys
/var/lib/dbus
/var/log (/samba)
removed all stuff from /etc/rc.local
there’s some really nasty stuff in /etc/sudoers
disable ipv6: blacklist ipv6 module in /etc/modprobe.d/backlist.conf

Debian¶

dist-upgrade to squeeze
usb hdd standby → mine does it automatically
localepurge
dpkg-reconfigure -plow locales

Firewall & Router¶

Or you can use my firewall/routing script. It assumes two different and fully trusted networks (and interfaces) for the ethernet LAN and the wireless LAN, and a separate interface for the internet connection. It configures the firewall, the routing and NAT for this setup. See the script (comments) for details.

flipfirewall-1582.sh
- installation:
  - copy to /etc/init.d/flipfirewall,
  - chmod a+rx /etc/init.d/flipfirewall,
  - edit the configuration in the script (IF_EXT, IF_LAN, IF_WIR)
  - test with /etc/init.d/flipfirewall start
  - and activate: update-rc.d flipfirewall defaults

Compiling Stuff (Options)¶

native Debian for ARM (e.g. on the Plug)
cross-compilation using a toolchain from
- the Embedded Linux Development Kit (ELDK), or from
- the toolchain from EmbDebian (apt-get install emdebian-tools, emsetup --arch armel, arm-linux-gnueabi-gcc ...), or from
- Dan Kegel's Crosstool
