If you’ve got more than one computer running Debian that packages are downloaded through apt, then apt-cacher should help you a lot.
Apt-cacher is actually a cgi script that is run by apache. Using apt-cacher is very easy, and installing it is even easier.
Step 1: Install apt-cacher.
(Run this on the proxy computer)
apt-get install apt-cacher
Enter the webpage : http://localhost/apt-cacher
to see that the proxy is running.
Step 2: Backup and Convert Clients sources.list.
(Do this on the computers that you want to access the cache.)
cp /etc/apt/sources.list /etc/apt/sources.list.backup
Press ‘:’ while in vi.
%s/http:///http://[Your Proxy IP]/apt-cacher?//g”
This searches through your sources and adds http://[Your Proxy IP]/apt-cacher?/ before every repository.
An example from my sources.list looks like this:
deb http://192.168.3.2/apt-cacher?/www.backports.org/debian/ sarge-backports main
Step 3: Update Clients
Optional Step 4: Import Existing packages into the apt-cacher cache
Copy the desired packages to the proxy directory /var/cache/apt-cacher/import
Run the import script to make it so that apt-cacher can use them.
Step 5: Use apt-get
If the required previous steps completed successfully you should now be able to use apt with it’s connection proxied through your apt-cacher proxy.
