So the non-optimised debian setup hasn’t been working for me, so I’m using the raspbian distro now.

So I’ll be using the udisks-glue package.

Just add a line with udisks-glue into /etc/rc.local just before the “exit 0” line.

Then edit /etc/udisks-glue.conf to look (something like) this:

--- Start File ---
filter disks {
    optical = false
    partition_table = false
    usage = filesystem
}
match disks {
    automount = true
    automount_options = { sync, noatime, "dmask=0", "fmask=0" }
}
filter optical {
   optical = true
   usage = filesystem
}
match optical {
   automount = true
   automount_options = { ro, "mode=0444", "dmode=0555"  }
}
--- End File ---

Yes, the next bit of kit to try is the Raspberry PI.

I’m trying the “Softfloat” version of the Raspberry PI-based Debian installation. Currently, I’ve installed usbmount (to mount the SD card when it appears on the usb bus) and usb-switcher to punt it into 3G mode.

So, it currently mounts, but that’s about it. I can’t seem to find the “cdc_ncm” but it according to /proc/config.gz as it’s compiled in statically … More voodoo than what currently know about at the moment. The last linux kernel I compiled was a 2.4.xx ages ago.

So why do we want to duplicate the functionality of the E355?

Well, it seems to be limited to five devices, as I mentioned in an earlier post that I have massive problems with that, I don’t want to have to juggle tech to some arbitrary limit. Also, I’d like to support more services at some point (media streaming perhaps)

Like all the 3G dongles I’ve seen recently, they initially show up as CD-Roms. Then the “drivers” switch them over to being the actual device. In this case a Micro SD Card reader and a USB CDC device, in this case a USB ethernet port.

A long time ago, I was asked by a consultant friend of mine to have a think about being able to drop portable wireless internet repeaters. The brief was that first responders could drop a bunch of wireless mesh routers over the area so that computers could be used and contact base.

At the time the emergency department decided that it would be a luxury and unnecessary so I didn’t get to build a prototype.

First up, the battery pack.

The A10HZ from Maplin, a 5Ah 12v battery pack. This has 2x6v batteries internally, and a 200 W inverter, two accessory sockets, and two 12v terminal posts. It has a usb power socket and a light too, but the usb socket is tied to the inverter being on and the light is incredibly weedy, so we’re ignoring them for now.
