dnf and failing epel
by lejeczek 04 Nov '16

04 Nov '16

hi everyone, I use dnf but one epel fails in a peculiar way: $ dnf repolist Failed to open: /var/cache/dnf/x86_64/7/x86_64/7/epel/repodata/8415cbb16f52517f34e3edac12a97c9893117f7b9de6cb22fc086048febd1c60-updateinfo.xml.bz2. that file is there, so I tampered with perms & fcontext but to no avail. dnf clean does remove it but on the first contact to epel repo it fails again. Do you see it with your centoses? ps. I wonder if my email get though to the group, I receive mailing list emails but I don't get my own emails? b.w. L

I'd love to hear how's CentOS 7 support for E7470 hardware. Hi Milos, The Thinkpad T series and Latitude are *very* similar computers. They are both business "ultrabooks" with a 1600x1080 display option, nice keyboards (not "chicklet" style), a trackpoint and trackpad and RJ-45 builtin. I bought a Dell Latitude E7470 over the Lenovo for several reasons. One is this comment which is worth mentioning again: On Fri, Sep 30, 2016 at 11:58 PM, Gordon Messmer <gordon.messmer(a)gmail.com> wrote: > It's worth mentioning again that Dell is one of the companies doing the > development for the bits that don't work, and that those drivers are often > the ones that get Lenovo equipment going, too. Lenovo does not, to the best > of my knowledge, do any Linux development. Another reason is that I have heard about people having problems with Lenovo. Not just with software but with hardware malfunctions. I spoke to someone on the phone that had hardware problems with their new Thinkpad (although I suspect some of the problems could have been misdiagnosis by the user). After describing how nice the E7470 they're thinking about dumping their 1yo X250 and getting a Dell. As for the Carbon, that is a very different computer. The Carbon is an ultralight / thin Macbook-like machine with Windows so I have no advice for you there. I have not tried CentOS on the E7470 but I'm quite certain it would not work because I have tried the latest Fedora Live which is about 100 kernel revisions newer and even that doesn't completely work. Specifically, if I plug in an external display it freezes. My feeling is I need a newer display driver (and thus newer kernel). The only other issue I noticed was that wireless didn't work but it seems more like a glue issue and not necessarily a driver. Otherwise, suspend and everything else worked near as I can tell which is actually pretty impressive for a brand new machine. So, I am doing other things while this new E7470 ages like a fine wine. Or maybe I'll loose patience and just install Fedora and try a "vanilla" kernel package. Then maybe after a year or two CentOS 8 or whatever will run on it and then I can just run steady for 4+ years without getting pummeled by stupid updates and feature creep that you get with Fedora and Ubuntu or whatever the latest hot distro is. The E7470 is obviously a laptop of choice for business people. And that is the type of machine developers use. So chances of good compatibility are very high. You just have to give it time. I was watching Daredevil season 1 and they use Latitudes that look exactly like mine. And that was probably filmed in 2014. So the form factor at least has been around for a while which is good. Unfortunately I can't say the same thing about the show. Mike

CentOS repo issue
by m.roth＠5-cent.us 03 Nov '16

03 Nov '16

I just built these servers, and the other admin added some more packages, then we moved them into the datacenter. I see errors from a cron job, Could not get metalink https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=x86_64 error was 14: curl#6 - "Could not resolve host: mirrors.fedoraproject.org; Unknown error" So I logged on, and ran yum list apcupsd, to see if it was having issues getting epel, and got: Cannot find a valid baseurl for repo: base/7/x86_64 Clues for the poor? mark

fprintd needed?
by Jon LaBadie 03 Nov '16

03 Nov '16

On a 7.2 desktop system I see irregular attempts to start the fingerprint authentication daemon "fprintd". One of the messages is "D-Bus service launched with name: net.reactivated.Fprint" This fails as there is no fingerprint device. fprintd.service is disabled. Without a fingerprint device, is this software needed. Yum removal (aborted) shows no packages dependent on fprintd. Jon -- Jon H. LaBadie jon(a)jgcomp.com 11226 South Shore Rd.

Centos 7 Minimal and Quotas
by Matt 03 Nov '16

03 Nov '16

I have installed Centos 7 Minimal in a 1TB KVM. Used XFS file system. I did not use LVM. I need to install Directadmin which requires quotas. I have this in fstab: UUID=b482396d-d2fc-49ed-b9df-c49e9387405b / xfs defaults 0 0 UUID=e24a16e0-57ab-42b2-af0b-9edf789376e5 /boot xfs defaults 0 0 UUID=b08b8243-6b46-444c-a7bd-02934246d884 swap swap defaults 0 0 I get this: # repquota / repquota: Mountpoint (or device) / not found or has no quota enabled. repquota: Not all specified mountpoints are using quota. I tried changing / from defaults to defaults,usrquota,grpquota in fstab and rebooting but I still get the same result. What do I need to do here?

Disable calendar notification in GNOME / CentOS 7 ?
by Nicolas Kovacs 03 Nov '16

03 Nov '16

Hi, Here's one of the problems adressed in a previous thread, but it got somehow swept away in the heat of the discussion. Since I'm using Thunderbird and not Evolution, I'd like to get rid of the calendar notifications in GNOME's system menu. Ideally, things should work like this: https://extensions.gnome.org/static/extension-data/screenshots/screenshot_1… There's an extension called "Nothing To Do" which is supposed to do exactly that, e. g. get rid of the calendar notifications: https://extensions.gnome.org/extension/153/nothingtodo/ Unfortunately there seems to be no way to use it with the GNOME version shipping with CentOS. I spent a couple hours jumping through various burning loops, without success. Any idea how this could be done?

Thunderbird vs. Evolution vs. OwnCloud
by Nicolas Kovacs 03 Nov '16

03 Nov '16

Hi, I'm currently using Thunderbird synced to OwnCloud on my main workstation running Slackware64 14.1. I just installed CentOS 7 on my Asus S300 laptop. It's running nicely, and I'm spending some time getting acquainted with it. I wonder if I should stick with Thunderbird or go with the default Evolution application, since this seems to be better integrated into the desktop, namely the calendar function. On the other hand, it seems like you have to jump through burning loops to connect Evolution to OwnCloud. What are your experiences with these two clients and OwnCloud? Any suggestions?

Power Cut
by Hadi Motamedi 02 Nov '16

02 Nov '16

Dear All I am using a centos server for cdr billing and mediation device on a remote network. I am experiencing problem that I am suspicious it comes from main supply power cut at the remote site. The power supply to the remote site comes from battery charger that will be automatically switched in circuit under main supply power cut but cannot provide adequate power for more than 2 hours . I am suspicious that the remote system is suffering from many frequent main supply power cut . Can you please do me favor and let me know if there is any log on my centos server that I can check to see if there would be many frequent power cut there ? Thank you for your time

NetworkManager icon not showing
by Nicolas Kovacs 02 Nov '16

02 Nov '16

Hi, I just installed CentOS 7 on my Asus S300 laptop. Wireless was working OK at first, but now for mysterious reasons the NetworkManager icon seems to have disappeared from the notification area. When I click on that area, there's only information showing about sound, brightness, battery status and the connected user. Which leaves me clueless. Any suggestions?

CVE-2016-5195 DirtyCOW: Critical Linux Kernel Flaw
by Valeri Galtsev 02 Nov '16

02 Nov '16

Dear All, I guess, we all have to urgently apply workaround, following, say, this: https://gryzli.info/2016/10/21/protect-cve-2016-5195-dirtycow-centos-7rhel7… At least those of us who still have important multi user machines running Linux. (Yes, me too, I do have a couple, thank goodness, the rest are already not ;-) Have a productive weekend, everybody.

How to block routing/forwarding with firewalld
by Jeff White 02 Nov '16

02 Nov '16

On CentOS 7 with firewalld I have a box with numerous interfaces acting as a NAT gateway. This works but I noticed that it routes/forwards traffic not just from my internal zone to external zone but also between interfaces within the internal zone. How can I prevent that traffic? I've tried adding direct and rich rules to deny the traffic but it doesn't work. Direct: firewall-cmd --direct --add-rule ipv4 filter INPUT 0 -s 10.110.4.0/22 -d 10.110.0.0/22 -j REJECT That command works, and I see it in `iptables -L` but traffic is still allowed. Rich: # firewall-cmd --zone=trusted --add-rich-rule='rule family=ipv4 source address=10.110.4.0/22 destination address=10.110.0.0/22 reject' Error: INVALID_RULE: destination action I can't find any explanation of what that error means. So, how do you tell firewalld to stop forwarding traffic between interfaces? # firewall-cmd --get-active-zones public interfaces: ens161 ens193 trusted interfaces: ens192 ens224 ens256 lo # firewall-cmd --list-all public (default, active) interfaces: ens161 ens193 sources: services: dhcpv6-client ssh ports: masquerade: yes forward-ports: icmp-blocks: rich rules: -- Jeff White HPC Systems Engineer Information Technology Services - WSU
