Linux modem tethering with berry4all, Rogers 3G network, and Blackberry Bold 9000

Because I'll be out of town for the next couple days, part of my packing list included setting up tethering via my Blackberry.

First I tried barry but was unsuccessful in trying to make a successful connection.

Then I found berry4all.

I had two problems, but thanks to the extensive FAQ, I managed to solve them:

  1. Ensure your device (in my case, Blackberry Bold 9000) has its APN correctly set in Setup > Options > Advanced > TCP
  2. Ensure other network connections are disabled using route -n; ifconfig -a before attempting to connect via tethered 3G modem. See also If your PPPD does not support replacedefaultroute
  3. Ensure /etc/resolv.conf is being correctly updated with the appropriate DNS entries (I have to do this by hand at the moment, but tweaked the default /opt/bbtether/berry4all.sh script to add this line so that I can automatically update the file immediately before connecting:
    #!/bin/sh
    cp -f /etc/resolv.conf.bbtether /etc/resolv.conf
    python bbgui.py &
    where /etc/resolv.conf.bbtether contains:
    domain rogers.com
    search rogers.com
    nameserver 64.71.255.198
    #nameserver 64.71.255.253
  4. Load up a bandwidth speed test such as bandwidthplace.com and see what network speed you can get.

Admittedly, tethered speeds are nothing close to wifi speeds.

  • With Rogers 3G network and Blackberry Bold 9000 attached via USB, I managed to get about 500-2800kbps down and 100-200 kpbs up.
  • With Rogers "Exterme" cable internet access (wifi @ home) I get 9800kbps down, 960kbps up.

But at least I can surf on my laptop using the 3G network while I'm away from the office.

To disconnect wired & wifi, then tether automatically and stay connected until CTRL-C is pressed, try this script:

#!/bin/bash
if [[ $UID != 0 ]]; then
 echo "Must be run as root!"
else
 /etc/init.d/network stop
 cp /etc/resolv.conf.bbtether /etc/resolv.conf
 route -n; ifconfig

 cd /opt/bbtether; python bbtether.py rogers -P **YOUR_DEVICE_PASSWORD_HERE**

 /etc/init.d/network start
 route -n; ifconfig
fi

Blackberry Linux Mail, Calendar, Tasks & Contact Sync, Part 2

Things have improved since my last post, despite the fact that I managed to kill Thunderbird along the way and lost a good chunk of today figuring out to restore it. Luckily I can read French, or I may never have found the solution to the elusive -203 problem.

Aside:

To recover from a corrupt Thunderbird profile, create a new profile using thunderbird -ProfileManager, then transfer your data to the new profile. Easy-peasy.

Next, reinstall all your extensions. I use these 15 extensions.

I've also managed to get barry to work for backing up my Blackberry on Fedora. Turns out the problem is that it simply needs root privileges.

Here's how the data flows, drawn with JBoss Tools' jBPM Graphical Process Designer:

I don't yet have a solution for Zimbra contacts & calendar being accessible on the Blackberry, short of manually duplicating entries from one repo to the other. Still, 5 out of 7 data sources synched is pretty decent.
