Login as SuperUser on Murmur / Mumble-server on Debian

I’m trying out Murmur / Mumble-server at the moment for conference calls and meetings for FSFE campaigns. The service is great, and audio quality top-notch. Installation and configuration was generally very simple.

In order to have private conversations however (where uninvited users cannot participate), you must first log in as the pre-configured admin user, called ‘SuperUser’. Achieving that was rather confusing on Debian, so for future reference, here’s how to do it.

  1. Set the SuperUser password via the Murmur server CLI:

    sudo /usr/sbin/murmurd -ini /etc/mumble-server.ini -supw <password>

    You must run the command as root, and you must specify the .ini file. Do not use murmur-user-wrapper, which Debian provides.

  2. Connect to the Murmur server using the Mumble desktop client, specifying username SuperUser, and the password that you set above.

Good luck!

USB Wifi for the SheevaPlug freedombox

After a few hours searching for a USB wifi adapter to purchase for my Debian Squeeze based eSATA SheevaPlug last weekend, I settled on one from Amazon.

Despite the availability of numerous adapters claiming to be compatible with various versions of GNU/Linux (or ‘Ubuntu x.xx compatible’ at least), few of them work with non x86/64 versions of Debian because they require the use of non-Free firmware which is only available for those two architectures. For example, the LM Tech Wireless n adapter has the following warning on its corresponding Wiki page.

Unfortunately I couldn’t find any 802.11n devices that looked like they would work with ARM versions of Debian, and it was often impossible to tell what chipset the advertised product was using (note to retailers: if the chipset cannot be easily determined then a whole market just ruled our your product!).

Therefore I reluctantly bought an 802.11b/g adapter using the RTL8187B chipset, which as far as I can tell from the Debian Wiki should work with all Squeeze architectures supported by the distribution.

It’s galling to have to pay more for an inferior product (I’ve previously purchased 802.11n adapters for £6 that worked with fedora out-of-the-box), but if the adapter works with my SheevaPlug when it arrives then all will be forgiven.

Look out for an update in the near future.

In the mean time please share your recommended Debian Squeeze ARM USB wifi adapters in the comments.


The adaptor that I purchased works perfectly with with my freedombox. A quick addition of my network password to /etc/network/interfaces, followed by the execution of ifup wlan0 was all that was required. The adaptor in question is labelled “LogicPro”, and can be purchased from Amazon (don’t forget to use the FSFE donation add-on if you buy one!).
