Ubuntu 9.04 Synaptic Package Manager with ISA proxy

After installing Jaunty on my work laptop, I was having trouble getting apt / Synaptic working, despite system-wide settings for proxy, and application specific settings.

After trawling teh intarweb, I came up with this...

http://cntlm.wiki.sourceforge.net/

Download and install the .deb, edit /etc/cntlm.conf then start cntlm with this command:

sudo /etc/init.d/cntlm start

Configure Synaptics proxy to localhost:3128 and all should be well :-)

(Newbie way to edit the conf file is to hit ALT+F2 and run the command sudo gedit)

To set the proxy for your apt, add the following line to "/etc/apt/apt.conf.d/00proxy" or "/etc/apt/apt.conf" :
Acquire::http { Proxy "http://IP.OF.YOUR.PROXY:PORT"; };

If you frequently set up posix boxes, install this to a system (physical or virtual) on your LAN (installs a daemon):
apt-get install apt-cacher.ng

This sets up a local repository that remains current.
Accessible via: http://IP.OF.THE.PROXY:3142

Easy as pie, and greatly reduces network load
