MATE 1.20 test build for CentOS 7 available
by Greg Bailey 14 Oct '21

14 Oct '21

Hi everyone, There's been discussions in the past about updating MATE RPMs in EPEL-7: https://bugzilla.redhat.com/show_bug.cgi?id=1436260 https://lists.centos.org/pipermail/centos/2019-August/173154.html (and lots of others...) As a proof-of-concept, I've written some scripts that clone specific commits from the Fedora master branches, and then runs a tool to re-apply RPM scriptlets that are required by EL7 but removed from the Fedora .spec files. The scripts are available at: https://github.com/gebailey/mate-rpms/tree/master/1.20/el7 There's also instructions there if you want to try upgrading to MATE 1.20 w/o rebuilding them yourself. If these packages work for others, perhaps we can revisit the idea of updating the epel7 branches of the Fedora git repos and submitting an official update. There's nothing here (yet) about building MATE 1.22 (which might require a newer gcc for EL7), or building anything on CentOS 8, but thought the CentOS 7 users might find this helpful. -Greg

Brother HL-L2360DW printing quality
by H 23 Jul '20

23 Jul '20

I have the above printer but have not been able to resolve issues with the printing quality in CentOS 7. The test page prints fine but when I print PDF-documents, most recently using Chinese fonts, it is lacking and the pages very hard to read. The settings in the Mate Cups configuration panel are fine and set to 600 dpi, the settings in the printer menu are all OK yet it prints more like maybe 150 or even 75 dpi. Any suggestion what might be wrong?

CentOS 7 kickstart repo directive
by isdtor 08 Feb '20

08 Feb '20

Is the kickstart repo directive broken under CentOS 7? Every attempt with a repo directive in the kickstart file fails during the software selection step. Removing the repo directives and the packages from those repos under %packages makes it work. On console 2, I have verified that the (NFS) repos specified in the kickstart file are mounted and that the repo metadata has been copied over to /tmp/yum.cache. One of the packages from one of the repos that is explicitly listed under the %packages section appears in packaging.log for dependency checking. The custom repos work fine with yum on a running machine, so there is no problem with the metadata. Logging is poor and does not log what is actually wrong.

Re: [CentOS] upg. CentOS 7.5 to 7.6: unable to mount smb shares - samba NT domain member using ldap

If you're using a real NT4 domain, then you shouldn't need a passdb backend at all. If you're not in an NT4 domain, then you should set "security = USER". The man page for smb.conf notes "This mode will only work correctly if net(8) has been used to add this machine into a Windows NT Domain." Did you add this host to a Windows NT domain, using "net join ..."?

CentOS 7.6 1810 vs. VirtualBox : bug with keyboard layout selection
by Nicolas Kovacs 20 Jan '20

20 Jan '20

Hi, I'm currently working on my next Linux book, which will be an elementary course about CentOS administration. I'm using VirtualBox for all the installer screenshots. Since CentOS has recently been upgraded to version 7.6, I thought I might as well base all book references on this version. So I downloaded the 7.6 1810 minimal ISO and started a fresh installation in VirtualBox. I'm using a Swiss French keyboard layout (ch-fr or fr_CH-latin1), so one of the first things I do in the installer is replace the default French AZERTY keyboard (since I use the french language) by a swiss french QWERTZ layout. Now when I reach this dialog in the installer and try do define my new layout, the slider in the selection window doesn't appear, and clicking on any of the first layouts doesn't do anything, so I'm basically stuck there. I'm running OpenSUSE Leap 15.0 KDE on my workstation, so I tried the same thing with the previous CentOS 7.5 1804 minimal ISO, and the keyboard selection dialog works perfectly. So my intuition would tell me that there's a nasty bug in the CentOS 7.6 installer. Maybe it went unnoticed, since most folks stick to the default keyboard layout selected in their language. Any suggestions ?

Problem with disconnecting SSH-sessions
by H 12 Jan '20

12 Jan '20

I am running CentOS 7 on a workstation and CentOS 6 and 7 on a couple of servers I am remotely connecting to using the same username and thus ssh configuration. However, one of the servers running CentOS 6 I keep getting disconnected from whereas I have no such problems with another CentOS 6 server and CentOS 7 server. The latter two are on two different hosted server setups far, far away whereas the problematic one is my own physical hardware in the same building. I have tried to make sure the sshd configuration on all servers are identical but still have this problem. I can rule out a general problem with the router in my office since all connections are via that router, the only difference is that the problematic server is in the same building and the connection loops back via the same router but through an external IP address. /var/log/secure on the workstation offers no clues with no messages regarding any disconnection. If anyone has suggestions what I should check, it would be greatly appreciated!

gcc 8/9 on CentOS 7
by sthustfo 09 Jan '20

09 Jan '20

I am looking to make use of gcc 8/9 on CentOS 7, which is currently with gcc 4.8.5. How do I go about doing this? SCL repository provides the same as part of devtoolset8, but devtoolset8 libstdc++-devel i686 package is missing, without which I can not build 32 bit applications. Are there any repository sources from where I can get this? Otherwise, I am open to building the packages from sources. Please let me know how can one go about this. Any suggestions and pointers appreciated.

Hi all, sadly there is no epel tomcat package so far. As per https://bugzilla.redhat.com/show_bug.cgi?id=1745960 there is no progress for three months. Is there any other third party repository which builds tomcat for centos/rhel 8? Thx Rainer

Nasty Fail2Ban update for Centos 7
by Allan 02 Jan '20

02 Jan '20

Hi all... Recently a new Fail2Ban was available among some other updates for my Centos 7 system, and I just updated all. It seems that was a very BAD idea. Just noticed that Fail2Ban have generated a 6MB error log because of the update, and FirewallD a 1MB log of errors ! (not sure if any of those were really working after this) ok, I'll just run yum downgrade fail2ban I thought. Naa, no way back - Epel doesn't have a fallback option ! Then gotta dig into Koji, to find the old version, download it, and downgrade to that - and pew, everything is back to normal. The old one seems to be version 0.9.7 and the new one is 0.10.4 I haven't had time to look into Fail2Bans info about these 2 version, but since there is a major version change - is it really possible to just upgrade these ? Sure, I would love to have a working 0.10.4 for my Centos 7 - but it shouldn't destroy my existing system - or it should at least warn me about that - or what to fix. Allan.

CentOS 7 as a Fibre Channel SAN Target
by Steffan A. Cline 02 Jan '20

02 Jan '20

For quite some time I’ve been using FreeNAS to provide services as a NAS over ethernet and SAN over Fibre Channel to CentOS 7 servers each using their own export, not sharing the same one. It’s time for me to replace my hardware and I have a new R720XD that I’d like to use in the same capacity but configure CentOS 7 as a Fibre Channel target rather than use FreeNAS any further. I’m doing virtualization and this will allow me to have failover from one node to the other since they’ll all be sharing the same export rather than me simply backing up to the FreeNAS server the way I am now. Does anyone know of any really good current articles that explain how to set up CentOS 7 as the target in such a configuration and also setting up CLVMd so they can all share an export over Fibre Channel from CentOS 7?
