fail2ban ban not working

I have fail2ban on my mail server monitoring Dovecot and Exim. I have noticed that it has stopped banning IP's.

C8.1 Grub problem
by Alessandro Baggi 08 Apr '20

08 Apr '20

Hi list, I reinstalled on my workstation CentOS 8.1. I explain: I'm a KDE user but packages shipped from EPEL currently are buggy so I prefer a stable and functioning system to work with. So I tried to remove KDE workgroup and installed group "Workstation" but the system bricked so I reinstalled with GNOME. I've an nvidia gtx 1050ti GPU so I installed kmod-driver from rpmfusion. After the installation of Nvidia driver, I rebooted, gdm start and after I perform the login the system freeze. So this problem happened to me with C7.5 and nvidia driver. In my case I need to blacklist i915 module and system works. Also in this case I tried to boot centos changing grub kernel parameters pressing 'e' in the grub menu and adding "i915.modeset=0 rd.driver.blacklist=i915", booted and system works. So I tried to make this permanent updating grub configuration adding the previous directives (and removed rhgb and quiet) to /etc/default/grub and run grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg. Reboot the system and checked again kernel parameters on grub menu and seen that nothing changed. Booted and freezed. I checked /boot/efi/EFI/centos/grub.cfg and kernelops has the new directives. Seems that grub configuration does not take effect. I made another test inside a VM installed with minimal selection and remove rhgb and quiet parameters and worked fine. The vm is BIOS and my workstation UEFI. How I can solve this problem? Currently to boot my system I need always to add this params. Thank you in advance

Welcome Thomas and Patrick to CentOS Project Governing Board (Karanbir Singh) ---------------------------------------------------------------------- Message: 1 Date: Tue, 7 Apr 2020 17:55:53 +0100 From: Karanbir Singh <kbsingh(a)centos.org> To: CentOS Announcements List <centos-announce(a)centos.org>, "The CentOS developers mailing list." <centos-devel(a)centos.org> Subject: [CentOS-announce] Welcome Thomas and Patrick to CentOS Project Governing Board Message-ID: <4bac266d-6ab6-0f81-47fe-dcd77d65ae57(a)centos.org> Content-Type: text/plain; charset="utf-8" Hi, The CentOS Governing Board of Directors is pleased to appoint two new Directors to be added to the Governing Board, effective 8th April 2020: Thomas Oulevey [1] and Patrick Riehecky [2]. The community will instantly recognise both from their long standing and well established support for the CentOS Project over the years, initially as consumers and community participants, and in more recent times as active across various initiatives in and around the project space. Over the last sixteen years the CentOS project has established itself as a critical component in the open source ecosystem online. In order to maintain this leading role and help drive success for the wider open source ecosystem, we are moving to a more contributor-centric model. A key part of enabling this goal is to evolve our transparent governance. Pat and Thomas have shown keen interest in participating in this specific endeavour, and we are excited to welcome them to the team, helping us get there. Thomas (alphacc) works in the Controls group within the CERN Beams department [3]. He has contributed to the CentOS Project since 2012, as a member of the infrastructure team. He helped to bootstrap a few Special Interest Groups, helped the QA team with reports, and now mainly designs and improves the Community Build Service [4]. Thomas?s sponsor on the Board is Mike McLean, who will help oversee his transition to project leadership. Patrick (jcpunk) works at Fermi National Accelerator Laboratory [5]. He is part of the Scientific Linux team [6] and works on systems that perform Data Acquisition for various experiments at Fermilab. Although a long time member of the community, formally Pat began working with the CentOS Community when Fermilab decided to use CentOS 8 [7] as its EL8-base platform. Pat?s sponsor is Johnny Hughes, who will help oversee his transition to project leadership. Please join me in welcoming them to the team, Regards Karanbir Singh Project Lead, The CentOS Project [1] https://wiki.centos.org/ThomasOulevey [2] https://wiki.centos.org/PatrickRiehecky [3] https://beams.cern [4] https://cbs.centos.org [5] https://beams.cern [6] https://www.scientificlinux.org/about/who-makes-scientific-linux/ [7] https://listserv.fnal.gov/scripts/wa.exe?A2=SCIENTIFIC-LINUX-ANNOUNCE;11d60…

RHEL 7.8 is out
by Phelps, Matthew 07 Apr '20

07 Apr '20

This is not your usual "so when is CO 7.8.xxxx coming out?" posts. I'm just curious if the CentOS team is affected by our current world conditions, or is work-from-home modus operandi for the team?

Fresh C 7 install, fully updated... but whenever I go to log off, whether with ctl-alt-delete, or from the menu, instead of logging me off, it restart X, with me still logged on. The second time I try, it logs me off. Anyone seen this behavior? mark

CentOS 8.1 cron does not send mail
by Tobias Kirchhofer 06 Apr '20

06 Apr '20

Hi, we experience difficulties with crond behaviour sending mail since CentOS 8.1. The cron job is the same like we used in CentOS 7. crontab -l /usr/bin/python3 -c 'import random; import time; time.sleep(random.random() * 3600)' && /usr/local/bin/backup.sh backup.sh writes the backup to the remote backup server. There are around 30 machines with the same cron job. The python part spreads the jobs over an hour so that the backup server is not struck at once from about 30 machines. The change in behaviour is that crond sends no mail anymore. It is because of the logical and (&&). Without this crond sends mails. What has changed in CentOS 8 and does anyone has an idea how we could fix it? Thank you! Tobias -- collect(a)shift.agency
