Hi Toby,

I've been successfuly using a squid cache to this extent. Set up one
machine to run a Squid. Point Apt on all machines including the Squid
host to the squid by placing the following in /etc/apt/apt.conf :

Acquire
{
http
{
Proxy "http://xxx.xxx.xxx.xxx:3128";
};
};

Ensure that /etc/apt/sources.list points to the same servers and uses
the same download method on all your machines

Now all updates should be cached in the Squid. Make sure you leave
enough room for all your updates and upgrades.

Alternatively you could use apt-proxy which is designed for this. Having
used this for a while I found it to be have defficiencies, particularly
with dropouts while downloading that made it pretty much inneffective
although there have been updates to the package since I last used it 12
or so months ago.

regards,
Adam
