Hello, in shim-x64-15-15.el8_2.x86_64.rpm of CentOS 8.3 I see the two files: ./boot/efi/EFI/centos/shimx64-centos.efi ./boot/efi/EFI/centos/shimx64.efi # ll boot/efi/EFI/centos/shim* -rwx------. 1 root root 1238416 Aug 1 2020 boot/efi/EFI/centos/shimx64-centos.efi -rwx------. 1 root root 1244496 Aug 1 2020 boot/efi/EFI/centos/shimx64.efi What is the difference?

by lejeczek 16 Feb '21

16 Feb '21

Hi devel I've noticed a while ago that Redhat's Bugzilla has had, in "Red Hat Enterprise Linux 8" as one of the options "CentOS Stream" - which is where I've been recently reporting to. But I wonder about bugs relating to CentOS infra/repos - where to submit those, would you know? many thanks, L.

Delta Chat on CentOS 7
by H 14 Feb '21

14 Feb '21

Has anyone compiled Delta Chat to run on CentOS 7? I know it is available as a Flatpak and as an AppImage (https://delta.chat/en/download) but I wonder if there might be benefits to compile and run natively on CentOS.

Changing command line version of php for apache
by H 14 Feb '21

14 Feb '21

I have updated php on a Centos 7 system to use php 7.2 from sclo. Apache running on the system is also using php 7.2 as shown by phpinfo(), however, apache continues to use the default version of php, ie 5.4.16, when that user launches a process from the command line. All other users default to php 7.2 when running from the command line which is correct. For some reason I have missed configuring apache php-cli correctly. I have googled and found many examples on how to change the configuration settings so that apache uses php 7.2 when serving web pages but in this case it is php-cli that needs to be corrected to use a later version. What should I check? What have I missed? By the way, I am not planning to remove php 5.4 from the system since it might be needed for something at a later time. Thanks.

CentOS 7, selinux and pop_port_t
by H 12 Feb '21

12 Feb '21

I am muddling my way through learning selinux when installing a webapp with httpd as the webserver running CentOS 7. The app allows the user to send/receive mail etc but it seems that I have yet to allow access to imap port 993. So far it seems this is configured through pop_port_t but setsebool httpd_can_network_connect 1 does not include pop_port_t. In the audit log I have: type=AVC msg=audit(1613093671.415:155086): avc: denied { name_connect } for pid=22431 comm="httpd" dest=993 scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:object_r:pop_port_t:s0 tclass=tcp_socket permissive=0 Yet, running the below sesearch -A -s httpd_t -c tcp_socket -p name_connect -d -C tells me ET allow httpd_t pop_port_t : tcp_socket name_connect ; [ httpd_can_sendmail ] I am obviously missing something. Does anyone know how to enable access to pop_port_t?

Update - Resizing a QEMU guest display
by Bill Gee 11 Feb '21

Strahil Nikolov and I took this conversation off-line for a few days. The thread of our discussion is below. Net result: No solution is yet found. Strahil had some very good ideas, but they did not pan out in this case.

I am not familiar with any remote access application called "spice". I have tried two methods of accessing the host. First is to open it from the Virtual Machine Manager on the host. Second is to use TigerVNC to access it across the local network. > > > > > > > > > > > > > > > > I see a package installed on the guest which looks like the guest agent. Is there more that needs to be added? This is the only qemu package installed on both the Fedora machine that does not resize and the CentOS7 machine that will resize.

One of them is called "qemu-device-display-qxl" which is very suggestive.

Re: [CentOS] udev rules & USB devices - ignored at boot
