Re: [CentOS] cli Checking disk i/o

OK. That is interesting. I am assuming tps is transfers per sec? I would have to get a stop watch, but it seems to go a bit of time, and then a write. Is there something that would accumulate this and give me a summary over some period of time? Of course it better NOT be doing its own IOs...

Hi folks I'm having some hard time troubleshooting a Wifi issue Centos7, fully up to date, with an Intel Dual Band 3160 Wireless adapter After the machine boots, the Wifi connects and runs ok for a few hours After this, the Wifi just stops [root@orbex ~]# lspci -v | grep Wireless 04:00.0 Network controller: Intel Corporation Wireless 3160 (rev 83) Subsystem: Intel Corporation Dual Band Wireless AC 3160 [root@orbex ~]# grep iwlwifi messages Nov 10 03:44:02 orbex kernel: iwlwifi 0000:04:00.0: Error sending SCAN_OFFLOAD_REQUEST_CMD: enqueue_hcmd failed: -5 Nov 10 03:44:02 orbex kernel: iwlwifi 0000:04:00.0: Scan failed! ret -5 Nov 10 03:44:02 orbex kernel: iwlwifi 0000:04:00.0: Failed to wake NIC for hcmd 100s of similar lines Nov 10 14:55:01 orbex kernel: iwlwifi 0000:04:00.0: Failed to wake NIC for hcmd Nov 10 14:55:01 orbex kernel: iwlwifi 0000:04:00.0: Error sending SCAN_OFFLOAD_REQUEST_CMD: enqueue_hcmd failed: -5 Nov 10 14:55:01 orbex kernel: iwlwifi 0000:04:00.0: Scan failed! ret -5 Nov 10 14:56:37 orbex kernel: iwlwifi 0000:04:00.0: loaded firmware version 17.3216344376.0 op_mode iwlmvm Nov 10 14:56:37 orbex kernel: iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 3160, REV=0x164 Nov 10 14:56:37 orbex kernel: iwlwifi 0000:04:00.0: base HW address: 34:de:1a:f0:c2:fb Nov 10 14:56:38 orbex NetworkManager[1154]: <info> [1573394198.8523] rfkill1: found Wi-Fi radio killswitch (at /sys/devices/pci0000:00/0000:00:1c.3/0000:04:00.0/ieee80211/phy0/rfkill1) (driver iwlwifi) [root@orbex log]# Any advice?

Need help modding src.rpms to generate complete SAMBA AD DC binary RPMs for CentOS 8
by Robert G (Doc) Savage 09 Nov '19

09 Nov '19

When RHEL8 and CentOS8 were released, I was looking forward to setting up SAMBA as a AD DC server for CentOS8. But when I lifed the hood on the samba.spec file I found the option to build the samba-dc binary rpm has been disabled for rhel family builds. Apparently Red Hat does not want to support a unified SAMBA AD DC environment. I believe we have all of the componentns needed to set up a fully up-to-date samba-dc binary. But it's been decades since I last rolled up my sleeves with my hardbound copy of "Maximum RPM" and built custom binary rpms. Has anyone already done this as a COPR or similar project? Failing that, I'm willing to work with anyone with more up-to-date rpmbuild tools to create and document the process. --Doc Savage Fairview Heights, IL

Hello, can someone explain these errors Oct 27 15:34:05 vhost01 named[1316]: zone #ZONE#/IN/auth: refresh: retry limit for master IPV6-MASTER#53 exceeded (source IPV6-THIS#0) Oct 27 15:34:05 vhost01 named[1316]: zone #ZONE#/IN/auth: Transfer started.

yum install fails - itertoolsmodule.so
by Gary Stainburn 08 Nov '19

08 Nov '19

I've just tried a yum update on one of my C7 boxes and got the following output. I'm guessing to fix this I need to re-install the RPM, but I can't remove it because of dependancies, so how can I fix the problem? I've managed to download a later version of the RPM, but haven't managed to find the same version as the one installed. Gary [root@zeppo ~]# yum install There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: /usr/lib64/python2.7/lib-dynload/itertoolsmodule.so: cannot read file data: Input/output error Please install a package which provides this module, or verify that the module is installed correctly.

Possible Font problem with CentOS 7
by Tony Molloy 07 Nov '19

07 Nov '19

Hi, I've got a possible font problem with a fully updated CentOS 7 system. An example with the man command. #man kill Should return the following KILL(1) User Commands KILL(1) NAME kill - terminate a process SYNOPSIS kill [-s signal|-p] [-q sigval] [-a] [--] pid... kill -l [signal] but what I actually get is the following KILL(1) User Commands KILL(1) kill - terminate a process [ signal| ] [ sigval] [ ] [ ] pid... [signal] Notice the missing text. If I select the text and paste it into an editor I see the missing text. So it's there just not displaying on the screen. I also notice the effect with links embedded in e-mails. I use evolution. Embedded links do not appear in the e-mail but if I hover over a link location then it appears in the text box at the bottom of the page and I can select it. I suspect I'm missing some common font(s). Any ideas. Regards, Tony -- Tony Molloy <tony.molloy(a)ul.ie> Home
