SELinux is preventing 11-dhclient from add_name access on the directory chrony.servers.wlp8s0.
by Ger van Dijck 02 Dec '19

SELinux is preventing 11-dhclient from add_name access on the directory chrony.servers.wlp8s0. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that 11-dhclient should be allowed add_name access on the chrony.servers.wlp8s0 directory by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c '11-dhclient' --raw | audit2allow -M my-11dhclient # semodule -X 300 -i my-11dhclient.pp Additional Information: Source Context system_u:system_r:NetworkManager_t:s0 Target Context system_u:object_r:dhcpc_state_t:s0 Target Objects chrony.servers.wlp8s0 [ dir ] Source 11-dhclient Source Path 11-dhclient Port <Unknown> Host castor Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.4-40.fc31.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name castor Platform Linux castor 5.3.12-300.fc31.x86_64 #1 SMP Thu Nov 21 22:52:07 UTC 2019 x86_64 x86_64 Alert Count 2 First Seen 2019-11-30 18:03:35 CET Last Seen 2019-12-01 11:16:46 CET Local ID 0370e7fd-a826-4c80-8239-747a7528c5af Raw Audit Messages type=AVC msg=audit(1575195406.740:277): avc: denied { add_name } for pid=1466 comm="11-dhclient" name="chrony.servers.wlp8s0" scontext=system_u:system_r:NetworkManager_t:s0 tcontext=system_u:object_r:dhcpc_state_t:s0 tclass=dir permissive=0 Hash: 11-dhclient,NetworkManager_t,dhcpc_state_t,dir,add_name -- Using Opera's mail client: http://www.opera.com/mail/

several VMs have suddenly quit working, in VBox.
by Fred Smith 02 Dec '19

02 Dec '19

Hi all! I have several VMs, all in virtualbox 6.0.14 and all the VBOX add-ons are up to date. I don't use them daily, last used any of them probably 4-6 weeks ago, pretty sure it was already running 6.0.14 by that time. they were all fine when last used. Two of them are C7, one is a clone of the other, and the other is C8. each seems to have different symptoms. the C7 clone claims there is no initramfs, no matter which kernel I try to boot.

CLAMD and EXIM - anyone got it working`
by Gary Stainburn 01 Dec '19

01 Dec '19

Has anyone actually got CLAMD and EXIM working? I've just had a go on a new VPS server without success. The only thing that happened was that my server slowed because clamd was hogging CPU. I have done a lot of googling and all I found was a couple of howto's that said the same thing, and my questions from 2015 which is the last time I tried this. I can get clamd / freshclam etc installed, although from the two howto's I worked from I had to edit / create service files and edit config files. However, I still do not manage to get a clamd.exim socket created on my system.

External HD partitioning & formatting considerations
by Nicolas Kovacs 01 Dec '19

01 Dec '19

Hi, One of my clients has a mixed Linux/Mac OS/Windows environment in his office. He just purchased a 4 TB external hard disk, which he intends to use on his various workstations. Up until recently, I've been using plain old MBR/FAT for hard disks in mixed environments. Fire up fdisk, make one big 0b type partition, and then format it using mkdosfs. Unfortunately, there's a 2 TB limit to that. Of course, I could still use a GPT partition, but then I'd still have to format it using a "common denominator" filesystem, e. g. FAT... which is also limited to 2 TB as far as I know. So what now? Use Windows 10 to format the disk using NTFS? This, Windows and Linux could use it, and I'd have to check if Mac OS can manage NTFS file systems. A few years ago, it didn't. Any suggestions?

systemd: Failed unmounting /var on reboot, should I worry about fs corruption?
by Ján Lalinský 30 Nov '19

30 Nov '19

Hi all, I have Centos 8 installed on a physical machine (www6) with separate LVM volumes for /, /var, /var/lib/mysql etc. System boot proceeds without a hiccup, in terminal systemctl status says everything is OK and running, journalctl says so as well - systemd mounts everything stated in fstab. However, on reboot systemd echoes problems with filesystem on /var : ...// unmounting all volumes Nov 26 23:51:30 www6 systemd[1]: Unmounting /var... Nov 26 23:51:30 www6 umount[2118]: umount: /var: target is busy. Nov 26 23:51:30 www6 systemd[1]: Stopped target Swap. Nov 26 23:51:30 www6 systemd[1]: Deactivating swap /dev/disk/by-label/lv_swap... Nov 26 23:51:30 www6 systemd[1]: var.mount: Mount process exited, code=exited status=32 Nov 26 23:51:30 www6 systemd[1]: Failed unmounting /var. Then proceeds and reboots the machine. This occurs on every reboot. Did anybody here encounter similar problems on reboot? I found this bug https://github.com/systemd/systemd/issues/867 which was closed without a definitive solution, the developer says the issue is hard to solve and just cosmetic since /var gets unmounted in the end anyway, which is strange because there is a log line about unmounting just about every other mountpoint and in the end of the journal, there are about 7 log lines about unmounting swap volume, but zilch about /var. If the system is getting down without proper unmount, data corruption can happen. I would feel much better if there were no such errors...

Help with dracut install CentOS 8
by Jerry Geis 29 Nov '19

29 Nov '19

I am trying to specify a static IP on the new dracut format. I was using this: http://man7.org/linux/man-pages/man7/dracut.cmdline.7.html So my grub entry consists menuentry "Install CentOS 8" { linux /boot/vmlinuz noverifyssl ks=https://something ip=192.168.1.3::192.168.1.1:255.255.255.0::eth0:on:192.168.1.1 biosdevname=0 net.ifnames=0 ksdevice=eth0 inst.sshd sshd=1 initrd /boot/initrd.img } This seems OK to me. But rebooting to start the install for CentOS 8 it just stops and says "system halted". the lines above that have no errors. .3 is the IP I want to use .1 is the GW and the Nameserver in this case. Thanks, Jerry

printer frustrations
by mark 26 Nov '19

26 Nov '19

I've got an old HP LaserJet 1018. It's a winprinter. After I bought a new router (to go inside the Verison one), I plugged it directly into my box (ok, via a hub). I run CentOS 6. Before we went on the trip, I could print, I upgraded my system, and this is the first time I'm trying to print... and no joy. I've tried sending the firmware to it via lp -o raw ... -h :9100, and maybe? it worked, but no printing. I've upgraded to the latest foo2jzs driver and .ppd, and nothing. Any ideas? CUPS since to think it can talk to it.... Yes, the system can see the printer.... mark
