Centos Stream mirror recreation
by Hostico 26 Apr '24

26 Apr '24

Hello, we had some hardware issues with out mirror server (https://mirrors.hostico.ro) which caused it to be offline for about 24hours and then took some time to resync everything. In the meantime our epel (https://mirrors.hostico.ro/fedora/epel/) and centos-stream (http://mirrors.hostico.ro/centos-stream/) mirrors were taken offline due to crawl errors. I updated the host from the mirror managed admin panel a couple of days ago but since the links didn't reappear online and the server was not crawled i tried deleting and readding the categories. To my surprise i was only able to readd the "Fedora EPEL" category . Is there a way to readd the Centos-stream one or should i just stop syncing it ? Thank you. -- ------ Regards, Sebastian Bobriuc https://hostico.ro

Even better, that sounds like useful traffic and I have around 15 GBit/sec to spare for that :) -- Dr. Carsten Otto http://verify.rwth-aachen.de/otto/

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/
