GNOME lockscreen freeze on notification
by Nicolas Kovacs 18 Aug '18

18 Aug '18

Hi, I just installed CentOS 7 with GNOME on my new Dell Latitude E6230 laptop. So far, everything runs nicely. I just have one problem with the GNOME lockscreen. I launched the OwnCloud client and started to synchronize about 20 GB of data from my OwnCloud server. During the sync, I left the laptop unattended. After about 15 minutes, the desktop was replaced by the lockscreen, as it should. As soon as the OwnCloud sync was finished, there was a corresponding notification that displayed on the lockscreen. Usually I hit [Enter] to exit the lockscreen by providing my user password. Only this time nothing happened. The lockscreen seemed to have frozen with the notification in the center. To exit it, I had to hard reset my laptop. Anyone knows what could be the problem here?

Old kernel bug back in CentOS 6.10?
by Matthias Bethke 16 Aug '18

16 Aug '18

I updated a few hypervisors and their VMs to CentOS 6.10 on Monday; today I awoke to an alert saying all VMs are down. It looks like a very old bug crept back in. The machine is a ProLiant DL380 G7 with Xeon X5675 and 96 GB, running half a dozen smallish VMs. Hypervisor and all VMs have kernel 2.6.32-754.2.1.el6.x86_64. Around the time the VMs must have gone down, there are quite a few error messages like the following in the system log: Aug 16 03:10:13 hyper-7 kernel: [265397.382552] vmwrite error: reg 6000 value fffffffffffffff7 (err -9) Aug 16 03:10:13 hyper-7 kernel: [265397.421372] Pid: 9375, comm: qemu-kvm Not tainted 2.6.32-754.2.1.el6.x86_64 #1 Aug 16 03:10:13 hyper-7 kernel: [265397.464985] Call Trace: Aug 16 03:10:13 hyper-7 kernel: [265397.481530] [<ffffffffa0532a9c>] ? vmwrite_error+0x2c/0x30 [kvm_intel] Aug 16 03:10:13 hyper-7 kernel: [265397.520737] [<ffffffffa0532ac0>] ? vmcs_writel+0x20/0x30 [kvm_intel] Aug 16 03:10:13 hyper-7 kernel: [265397.560028] [<ffffffffa0535e63>] ? vmx_fpu_activate+0x93/0xc0 [kvm_intel] Aug 16 03:10:14 hyper-7 kernel: [265397.600072] [<ffffffffa04cd1e7>] ? kvm_arch_vcpu_create+0x37/0x50 [kvm] Aug 16 03:10:14 hyper-7 kernel: [265397.638183] [<ffffffffa04c72a1>] ? kvm_vm_ioctl+0x601/0x1050 [kvm] Aug 16 03:10:14 hyper-7 kernel: [265397.674367] [<ffffffff8113f461>] ? free_one_page+0x191/0x440 Aug 16 03:10:14 hyper-7 kernel: [265397.708101] [<ffffffff811b4159>] ? vfs_ioctl+0x29/0xc0 Aug 16 03:10:14 hyper-7 kernel: [265397.739124] [<ffffffff81142d86>] ? __free_pages+0x46/0xa0 Aug 16 03:10:14 hyper-7 kernel: [265397.773193] [<ffffffff811b463a>] ? do_vfs_ioctl+0x3aa/0x590 Aug 16 03:10:14 hyper-7 kernel: [265397.805774] [<ffffffff81142e29>] ? free_pages+0x49/0x50 Aug 16 03:10:14 hyper-7 kernel: [265397.839147] [<ffffffff811b48a1>] ? sys_ioctl+0x81/0xa0 Aug 16 03:10:14 hyper-7 kernel: [265397.870109] [<ffffffff810f1d0e>] ? __audit_syscall_exit+0x25e/0x290 Aug 16 03:10:14 hyper-7 kernel: [265397.909358] [<ffffffff81560351>] ? system_call_fastpath+0x2f/0x34 Curiously, the messages don't seem to indicate anything fatal in and of themselves; there are a two like this a minute after bootup and like a dozen more after about a day, none of which seems to have crashed anything. However, it's the only obvious anomaly I could find around the time and as it's VT-x related, I reckon there's a connection. The stack trace closely resembles this bug that turned up in 2015 and was fixed long ago: https://lkml.org/lkml/2015/7/3/288 Has anyone seen this recently and could confirm or refute any of my guesswork? Cheers, Matthias

Docker + firewalld
by Todor Petkov 15 Aug '18

15 Aug '18

Hello, I am using Centos7 + Docker CE (docker-ce-18.03.1.ce-1.el7.centos.x86_64), in the following setup 1) On interface br-ee1ac3f6bbaf I have network 172.16.26/24 2) Network from (1) is routed via the IP address of eth0 of the CentOS machine 3) Access to machines in network (1) is direct, without port forwarding I want to be able to reach other machines in other subnet from the IP address of the Docker containers. I ran the following command: firewall-cmd --direct --permanent --add-rule ipv4 nat POSTROUTING 0 -i br+ -o eth0 -s 172.16.26.0/24 -j ACCEPT However, the firewall rules for NAT are: -A POSTROUTING -s 172.16.26.0/24 ! -o br-ee1ac3f6bbaf -j MASQUERADE -A POSTROUTING -j POSTROUTING_direct -A POSTROUTING_direct -s 172.16.26.0/24 -i br+ -o eth0 -j ACCEPT With this, it always goes via MASQUERADE first, without hitting the POSTROUTING_direct chain. Is there a way to add this rule on top of POSTROUTING? Regards,

USB disk IO

Hello - frequently I turn on my external USB 3.0 disk and back. While my machine is copying and backing up my desktop becomes very sluggish. Is there a way to change that ? I am using CentOS 7.5 x86 with a very nice processor extra cores available and plenty of memory. There is no reason the "other" cores cannot keep the desktop going. Thanks, Jerry

Sending mail from CentOS7 VM to FX ApeosPort-IV C4475 problem
by マスターズ　イアン 15 Aug '18

15 Aug '18

Hi Folks I'm a long term Linux user but have never used CUPS until this week. I'm trying to print from a CentOS7 VM to a Fuji Xerox ApeosPort-IV C4475 printer which requires a user name to be specified but no password. CUPS reports jobs are complete but nothing appears at the printer. This is what I've tried: 1. I downloaded the linux printer driver from the Fuji Xerox website and installed it and its accompanying printer utility. 2. I've followed various guides for setting up the printer in CUPS as an LPR connection as that is what my Windows machine uses. 3. I used the print utility (fxlputil) to specify my user name as I have to with Windows. However I have a sneaky feeling that nothing is arriving at the printer (whose admin info I don't have access to). I know the connection is OK: /usr/lib/cups/backend/snmp 172.16.58.222 gives: network socket://172.16.58.222 "Unknown" "FUJI XEROX ApeosPort-IV C4475 v 34. 52. 0 Multifunction System" "MANUFACTURER:FUJI XEROX;MODEL:ApeosPort-IV C4475" "" But lpinfo -l -v gives alot of "make-and-model = Unknown" messages. What can I can try to get more information or to get this working? Sorry if my information is vague. As I said, I'm only just starting to dip my feet in the pond of CUPS and it hasn't been very successful so far. Thanks in advance for any assistance. Ian
