Connecting to Juniper VPN with Ubuntu 10.04 64bit

Ran into my first snag. Apparently the Juniper Network Connect client for Linux doesn't like 2 things about the defaults installed on Ubuntu 10.04 64bit:
  1. Requires the Sun JRE/JDK, not the OpenJRE/OpenJDK installed by default.
  2. Requires the 32bit JRE, not the 64bit JRE
Obviously frustrating. I found the following resources to overcome this problem:

Switching from OpenJRE/JDK to Sun's version (without uninstalling, due to dependency issues).
Setup the 32bit JRE to run alongside the 64bit, and Download and modify the junipernc script by pointing it to the 32bit version. To do this, add this line after the # lines at the beginning:
export JDK_HOME=/usr/lib/jvm/ia32-java-6-sun

Test your setup here when you're done.

To reconnect after disconnecting, you might need to relogin to the vpn website and then run the connection script again. The session doesn't always exit nicely.

The big downside to all this is that you'll now have 3 different Java environments installed on your machine. Figuring out which one is running for what can be a bit tricky. It would be ideal for Ubuntu to allow either environ to begin with, but I understand why they can't do that.

Black Cursors on Win7/2008 R2 Using rdesktop for Ubuntu 10.04

I recently setup a Win 2008 R2 VM and proceeded to remote connect to it from Ubuntu 10.04. Everything worked perfectly except the mouse cursors were black (and some were corrupt). Solution? Use a newer version of rdesktop that doesn't ship with Ubuntu. There is a handy PPA that can be added using the following command: sudo apt-add-repository ppa:ricolai/ppa sudo apt-get update sudo apt-get install rdesktop [UPDATE] It appears ricolai may have removed the package from his PPA. To remedy the situation, I've uploaded the working binaries for x64. Sorry, I don't have the x86 any longer. More information on the bug can be found here: https://bugs.launchpad.net/ubuntu/+source/rdesktop/+bug/385974?comments=all

Long Time, No Write

It's been a loooong time since I last wrote. The past several years have seen a huge shift in my career and technical objectives. I've gone from working almost exclusively on code to selling software as a technical sales engineer to now managing a team of technical gurus doing sales worldwide. As a result, my time for tinkering has slowed considerably. I do want to update everyone by saying that I am now back to Linux after many years stuck in a Windows world for work. My current employer is focused on open source technology and as such encourages us to use Linux and other open source tools in any way we can. I am now the proud owner of a Dell Laptop that has dual-boot setup for Windows and Ubuntu 18.04. I'll try to write up a post here in the next bit about my experiences so far, but my quick and dirty summary is that you should definitely give it a shot. There are a few hiccups to overcome, but, for the most part, it's been really nice transitioning back. Until ...
