SELinux denies login
by Gordon Messmer 13 Apr '20

13 Apr '20

We have a CentOS 7 workstation whose user has started reporting periodic login failures. This seems to be the result of the krb5 cache aging out, and sssd's krb5_child attempting and failing to remove the old cache file. The AVC follows: type=AVC msg=audit(1586670874.327:73041): avc: denied { unlink } for pid=28735 comm="krb5_child" name="krb5cc_1985100122_oxJnH7" dev="dm-0" ino=67978294 scontext=system_u:system_r:sssd_t:s0 tcontext=system_u:object_r:tmp_t:s0 tclass=file permissive=0 The policy allows sssd_t to unlink user_tmp_type: sesearch -s sssd_t --allow: allow sssd_t user_tmp_type : file { ioctl read write create getattr setattr lock relabelfrom relabelto append unlink link rename open } ; Is the problem that the credential cache files in /tmp are being created with the wrong label, or is there some other problem I'm not seeing?

Display system logs in chroot ?
by kikinovak 12 Apr '20

12 Apr '20

Hi, This morning my day began quite badly, since my main production server wasn't responsive anymore. For public hosting I'm using a "Dedibox Pro" server at the french provider Online that's recently been acquired by Scaleway. I'm currently managing half a dozen public servers at that provider, all running CentOS 7. For debugging purposes, Online's web console enables you to boot the machine into a live rescue system, in that case Ubuntu 18.04. Once I managed to connect via SSH to the live system, here's what I did. Mount the root partition : # mount /dev/sda2 /mnt Mount the /boot partition : # mount /dev/sda1 /mnt/boot Then : # mount --rbind /proc /mnt/proc # mount --rbind /dev /mnt/dev # mount --rbind /sys /mnt/sys And then I chroot into the system : # chroot /mnt /bin/bash I had networking in the chroot environment. I tried to disable a handful of services like fail2ban and firewalld to begin with, but systemctl won't run in a chroot. So what I did was simply remove everything related to fail2ban and firewalld. Next thing was to look at the system logs to know what went wrong on startup, but I don't know how to do that from within a chroot. Any suggestions? Cheers, Niki PS : sorry for bad formatting. Since the unresponsive server is also running all my mails, I had to setup a Protonmail account to post on this list. Sent with [ProtonMail](https://protonmail.com) Secure Email.

Zoom?
by mark 11 Apr '20

11 Apr '20

Hi, folks, After I did a complete reinstall of current 7, with KDE instead of minimal, I'm mostly ok... except for Zoom. Has anyone gotten sound working with firefox? I get video, but it keeps claiming that my browser (the default firefox) can't access the system sound. Given that even as I type this, I'm streaming WUMB through its player.... I have noScript, but I enabled everything (except google-analytics), and no joy. I'd *really* rather use my browser than trust their app.... mark

CentOS 7 : broken dependencies
by Nicolas Kovacs 09 Apr '20

09 Apr '20

Hi, I got an alert from Yum-Cron this morning: Failed to check for updates with the following error message: Failed to build transaction: sclo-php72-php-pecl-imagick-3.4.4-1.el7.x86_64 requires libMagickCore.so.5()(64bit) sclo-php72-php-pecl-imagick-3.4.4-1.el7.x86_64 requires libMagickWand.so.5()(64bit) The CR repository is activated on this server, so I guess that's why. Which leads me to the more general question of: enable CR on a production server, yes or no? Pros : get security updates sooner Cons : expect breakage like the one above Any suggestions?
