These hosts are downloading packages, including some "basic" ones like perl, curl, python setuptools. I'll relax the fail2ban rules a bit and see how things evolve over time. Maybe everyone needs to rebuild everything once now, which obviously causes a bit of traffic. -- Dr. Carsten Otto http://verify.rwth-aachen.de/otto/

Does this also apply to this file? /fedora-epel/7/x86_64/repodata/f25bccaa54b08e731162aec431dd82887a5ed1abce8eb6f892ad41454f07e1f3-primary.sqlite.bz2 I have five hosts which each downloaded 4 GByte of this file in the span of 24 hours. The delay between two downloads varies, from a few seconds to a few minutes. -- Dr. Carsten Otto http://verify.rwth-aachen.de/otto/

Abusive repodata downloads
by Carsten Otto 02 Apr '24

02 Apr '24

Hi, I'm one of the admins of ftp.halifax.rwth-aachen.de, which offers fedora and fedora-epel among other distributions and projects. I've recently noticed that many Fedora users (including EPEL, CentOS, and BlackArch) frequently re-download "repodata" files that haven't been updated since the previous request. As some of those files are rather large ("filelists") and others are hit extremely often, I added fail2ban rules to deny users access to our service for some time. Please adjust your software so that file mirrors like ours are not (ab)used like this. Files that haven't been changed usually shouldn't be downloaded. Thanks Carsten -- Dr. Carsten Otto http://verify.rwth-aachen.de/otto/
