Some people asked how this differs from existing methods. Here are my experiences: 1. apt-proxy: While I love the concept of apt-proxy, it works very unreliably. Frequently, the proxy fails to download the package or imposes very long delays (#272217, and others). If it does work, it's a performance hog. On my Opteron 3600+, my mouse starts to go jaggy when more than one machine accesses the cache at the same time. I have always missed the ability to surf the local repository. 2. apt-cacher: Also a very nice concept, I have found it rather unusable. Clients would time out as the streaming does not work reliably. Also, after using it for a day or two, I found 30 or more Perl zombies on the system from the CGI. Here too, it is not possible to browse the repository. 3. squid: Squid works reliably, but it has no concept of the APT repository and thus it is impossible to control what is cached and for how long. The release-codename symlinks can be worked around with a simple rewriter, but other than that, there are three parameters that seem relevant: maximum_object_size 131072 KB cache_dir aufs /var/spool/squid-apt 1024 16 256 store_avg_object_size 100 Kb These values are what I came up with after two days of testing. The problematic one is the last one. It's at 13 Kb per default, and this causes squid not to reliably cache objects larger than 35 Mb. Increasing it to 100 Kb causes even openoffice.org to be cached for some time, but the high average also causes smaller files to be removed earlier than they should be. If you have a better squid configuration for Debian, please share it! Squid works, but by Murphy's law it has always pruned exactly those packages that I later need, which are larger than what my cable line can handle in a couple of seconds, and if I am under time pressure. Squid, too, does not allow to browse the archive. Thus, my proposal for an apache-integrated approach, which solves most of the issues above and appears to me to be very simple and transparent. -- Please do not CC me when replying to lists; I read them! .''`. martin f. krafft <[EMAIL PROTECTED]> : :' : proud Debian developer, admin, and user `. `'` `- Debian - when you have better things to do than fixing a system Invalid/expired PGP subkeys?
