For example network activity for the Nginx webserver process. #systemctl status netatop ● netatop.service - Netatop kernel module Loaded: loaded (/usr/lib/systemd/system/netatop.service; enabled; vendor preset: disabled) Active: active (exited) since Thu 2021-06-03 06:58:36 IST; 10min ago Docs: man:netatop(4) Main PID: 29083 (code=exited, status=0/SUCCESS) CGroup: /system.slice/netatop.service └─29086 /usr/sbin/netatopd Jun 03 06:58:36 marketplacedisruptionsuitevapt systemd[1]: Starting Netatop kernel module...

Hello All, At the moment im using http://mirror.centos.org/centos/8/ repo on my CentOS 8 host and I noticed, that im missing quite many new packages/updates what 8.4.2105 repo contains. Is there a possibility that they will also be transferred to on /8/ repo or should I start using /8.4.2105/ on my host ? Regards, Kimmo For Internal Use Only

kmod removal
by Emmett Culley 29 May '21

29 May '21

Sometime ago I thought I needed kmod-wl to support a new wireless card. Turns out I didn't need to do that. Now I'd like to remove kmod entirely. But when I try I get this: [root@ws1 etc]# dnf remove kmod Error: Problem: The operation would result in removing the following protected packages: systemd-udev (try to add '--skip-broken' to skip uninstallable packages) I am sure I don't want to remove systemd-udev, so I am a loss. I did disable akmods: systemctl disable akmods But I still see that kmod-wl is built each time the kernal is updated. Any suggestions where I can find out how to remove kmod. Note that searching the internet only brings me info on removing kmod-nvidia, and mostly on ubuntu, and they are no help because mostly what they discuss is how get back to neuveau. Even docs I've found that discuss how to install kmod on CentOS say nothing about removal. Emmett

non-functioning printer
by Michael Hennebry 20 May '21

20 May '21

In an attempt to diagnose a friend's HP Deskjet D1420, I'm running a Centos 6.10 LiveDVD. The readily visible symptom is that it will accept a job and claim to be printing it, but nothing ever gets printed, not even a test page. The same happens on her Ubuntu system. I recently learned that a blinking power light means that the printer is complaining about something. What? http://h10032.www1.hp.com/ctg/Manual/c00905267#d0e5511enww "If an error message appears Read the error message that explains the problem and its solution." Huh? Where on a Deskjet D1420 could an error message possibly appear? Does it mean this message in /var/cups/error_log? E [13/May/2021:15:18:53 -0400] [CGI] Unable to create avahi client: Resource temporarily unavailable E [13/May/2021:15:18:53 -0400] [cups-deviced] PID 2094 (dnssd) stopped with status 1! Would the presence or absence of whatever avahi is cause the printer to complain? The printer used to print. The hardware connection has not changed in years.

CentOS IRC channels moving to irc.libera.chat
by Rich Bowen 19 May '21

19 May '21

TL;DR: #centos and #centos-* are moving to libera.chat Over the past few days, there has been some upheaval on the Frenode IRC network, resulting in a number of the staff members quitting and starting a new IRC network. I wont attempt to explain all the details here, but you can read more at https://kline.sh which also links to other sources. The various ops have discussed the situation, and we intend to migrate all of the various #centos-* channels from Freenode over to irc.libera.chat over the coming days. This will take time, since libera is still spinning up, and some servers are moving from one network to the other. As libera is still in the early stages of setup, you may have significantly more timeouts/disconnects, netsplits and other issues for now. Until the new network is fully stable, we'll all continue to be present in the Freenode chanels. Please bring further questions to the IRC channels (on either network).
