So when I download +ISOs, I go directly to another mirror, use multiple connexions, to +download the ISO relatively fast, which is fine. + +For updates and incremental downloads it is much easier to use Rpmdrake. +However, often, after having selected a package, I get an error message +saying the package could not be downloaded because of a problem with the +mirror site. +(I suspect that usually the site is just not in sync.) + +MirrorBrain seems to be the perfect solution for this problem, as well +as dealing with partial mirrors. + +Interestingly, if for some reason a mirror site cannot carry a +particular package because of restrictions imposed by the country where +it is located, MirrorBrain will be able to cope. So that simplifies the +problem of dealing with legislative/copyright/patent restrictions as well. + +So at least 3 reasons to get MirrorBrain :) +><i> Cheers, +</I>><i> +</I>><i> Romain +</I>><i> +</I> +my 2 cents + +- André (andre999) + +</PRE> + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="001336.html">[Mageia-dev] Mirror tree structure +</A></li> + <LI>Next message: <A HREF="001332.html">[Mageia-dev] Mirror tree structure +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#1331">[ date ]</a> + <a href="thread.html#1331">[ thread ]</a> + <a href="subject.html#1331">[ subject ]</a> + <a href="author.html#1331">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-dev">More information about the Mageia-dev +mailing list</a><br> +</body></html> |
