Debian-multimirror is a tool that enables multithreaded mirroring for Debian, allowing for faster downloads and more efficient distribution.
One of the key features of Debian-multimirror is that it generates mirroring information from sources.list files. Also, it can exclude, include, or include the union of one or several lists of packages. For example, it can output dpkg --get-selections from several machines, leading to better mirror performance.
Debian-multimirror uses parallel programming, which makes it possible to exploit redundancy between mirrors and download from several mirrors simultaneously. This helps improve performance and reduces mirror load. However, it only uses one thread per mirror to avoid saturating an individual mirror.
The software tool also uses XML format for configuration files, which ensures that it is easy to use and edit. It handles missing files on a mirror and tries to retrieve them from other sources. Moreover, it checks the SHA1 and MD5 package information for data integrity.
Debian-multimirror has a custom algorithm that selects a consistent set of packages and currently chooses the most replicated package set. The package information data is big, so memory consumption is around 80 Mb in the common case and 30 Mb minimum for one distribution and one host.
In the most recent release, version 1.4.4, there is now support for signing Release files with gpg. Overall, Debian-multimirror is an excellent software tool for anyone looking to mirror a custom subset of Debian OS. Its numerous features and benefits make it stand out from other similar software tools available.
