firefox-60.5.0-2.el7.centos.x86_64 and Netflix

Hi all,

Since the last upgrade to firefox-60.5.0-2.el7.centos.x86_64 on my
CentOS 7, it is no longer possible to watch Netflix with my Firefox, it
always says that "Firefox is installing components needed to play the
audio or video on this page. Please try again later."
But nothing happens and Netflix is no longer readable with Firefox...
I tried downgrading to firefox-60.4.0-1.el7.centos.x86_64 and al is now
correct with Netflix...
Anyone had experienced the same behavior ?

CentOS 7, rsyslog and redis

Is there a sensible way to get rsyslog to talk to redis on CentOS 7.
The official way is to use the omhiredis plugin, but that doesn't seem
to exist in the CentOS 7 repositories? (It's how I do it on my Fedora
box.)

The long version:

I'm trying to rationalise logging and am using an ELK stack.

Latest kernel crashes X and gnome

Hi,

Anyone else having problems with kernel 3.10.0-957.5.1.el7.x86_64?

C7, enable an abrt for a daemon

I've mentioned here before that gssproxy is crashing all over the place
with a SEGV. However, there's no /var/spool/abrt/... when it does. How do
I enable the daemon to give me an abrt with information? I'm just not sure
of what the right word is for systemd, so online searching isn't always
useful.

Thanks in advance.

CentOS 6 and 389 Directory Server

I'm not sure it this is the correct location to ask these questions, but ...

In the past when I worked for a living the place where I worked had
thousands of RHEL Linux servers on various hardware, but the access was
controlled by Windows Active Directory and a third party piece of
software that was the middle-man between the 2.

Now that I no longer work I'm trying to build a CentOS Linux environment
where the access is controlled by 389-Directory Server.

systemd

Hi All - I have a systemd service file to start my application.

Part of my service file is:
[Service]
Type=forking
ExecStart=/path to start
ExecStop=/path to stop
RemainAfterExit=yes

This works fine "normally".

However - when I do a "yum update; and reboot" my script detects a kernel
change and now does a number of "recompiling" steps for drivers and such
before starting my application.

persistent generic device for tape changer

Hello,

mtx and therefor amanda use generic device /dev/sg<x> for tape changer.

These devices change on reboot.

How to make them persistent?

/dev/sch0 and /dev/sch1 seem to be persistent.

/dev/tape/by-id/ shows links from WWID to generic device

An UDEV rule could help? I have not found any example.

CentOS 7.6 update with gettimeofday()

In my app compiled on another linux I am getting
Assertion 'clock_gettime(clock_id, &ts) == 0' failed at
src/shared/time-util.c:34, function now(). Aborting.
when calling gettimeofday() on an update CentOS (did not fail in 7.5).
Is it possible that the update has changed the size of the types in the
timeval struct and causing the crash? Or has there be some for of bug
fix etc?

How do I get the system to actual download all current packages and

Back to c7 and firewalld

If I've missed someone's response, apologies.

As I said, my converted rules seem fine, and I can run the script that
issues a bunch of direct rules for the built-in FORWARD rule...

C7 and firewalld, ongoing

I've got my direct rules, converted from a C6 iptables-save. I load them -
they're to add to the built-in FORWARD chain. They all seem to load... but
then, when I try to --reload, I get
Error: BUILTIN_CHAIN: chain 'FORWARD' is built-in chain

and firewall-cmd --direct --get-all-rules returns nothing.

Bug in libreoffice or cups?

C7 My manager's manager sent out a ppt. Nothing fancy, no animation.

1. Page down doesn't get me to the next page.
2. Slide show decides that on my left monitor, it should fill the entire
monitor- no options, with the slide, and the next slide, and that my
right-hand monitor shuold be *COMPLETELY* filled with the slide.
3. Hitting <esc> gets rid of the one on the right... and anything then
crashes all instances of libreoffice.
4. I just tried to print it out...

CentOS 7 - AltArch i386 - DVD iso?

Just curious. In the two most recent releases of CentOS 7 AltArch i386
there has not been made available a DVD iso (or the live ones) alongside
NetInstall/Minimal/Everything. Any plans to make available the DVD
variation for the current or future releases?

For older 32-bit hardware, it can be nice to be able to burn a single layer
DVD.

Thanks for your time,

OVAL content

Hi all,
Much like Ubuntu and Debian teams have OVAL content published for detecting
vulnerabilities, are there plans of publishing such content? e.g.
<a href="https://people.canonical.com/~ubuntu-security/oval/" title="https://people.canonical.com/~ubuntu-security/oval/">https://people.canonical.com/~ubuntu-security/oval/</a>

On a related note, has anybody looked into using RHEL oval content on
CentOS?

C7, firewalld and rich rules

Hi, again, folks,

I'm trying to convert a number of iptables rules to firewalld rich
rules. I need to do this, because this is, in fact, a firewall, to
protect access to servers with sensitive data. It will limit access to
the servers behind it to a specific network, and nobody else, and allow
only certain services through.

What I've been trying to find is a script/program that converts the
output of iptables-save to something I can feed to firewall-cmd.
Anyone have a link to such?

I admit this is annoying.

Applying changes to route-eth0

I have a series of static routes in route-eth0

Recently I had to made changes and could not find an effective way to
get the old routes out and the new routes in.

ifdown-route seems to apply the content of route-eth0 to take down the
routes listed and ifup-route brings up routes based on route-

So what ends up is that the old routes never go away, just new routes added.

ifdown eth0; ifup eth0

works, but is a bit heavy-handed for only changing routes.

So how do I clear out the routing table and have it rebuilt based on
ifcfg-eth0 and route-eth0 without bouncing the interface completely

SELinux policy vs. static web content

Hi,

Some time ago I wrote an introductory article about SELinux on my blog.
I'm currently updating it for my new blog, and I found a curious change
in SELinux policy. Here goes.

For demonstration purposes, I'm using some static webpages, more exactly
the default pages found in /usr/share/httpd/noindex, which I simply
copied over to /var/www/html.

As a first practical example, I'm copying this stuff over to /tmp/backup
and then move it back again.

pip on C7

I am trying to install the python-onvif package on C7.

I did:
pip install onvif
Requirement already satisfied (use --upgrade to upgrade): onvif in
/usr/lib/python2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): suds>=0.4 in
/usr/lib/python2.7/site-packages (from onvif)
Requirement already satisfied (use --upgrade to upgrade):
suds-passworddigest in /usr/lib/python2.7/site-packages (from onvif)
You are using pip version 8.1.2, however version 19.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

How do I get it to go ahead

kernel boot issues

Hello,

I run CentOS release 6.10 (Final) on a Dell Inspiron M6700.

2.6.32-754.el6.x86_64 boots, and is whaat I am running now

none of these, updated ones, won't boot:

2.6.32-754.3.5.el6.x86_64

2.6.32-754.6.3.el6.x86_64

2.6.32-754.9.1.el6.x86_64

2.6.32-754.10.1.el6.x86_64

They all show the same 'symptom',  grub says it is booting that kernel,
screen blanks, solid corned in the left-top corner...  and that's whee
it stays.

I know this is vague, but any ideas?

Signature Pad (Evolis Signotec Sig100)

Everyone,

Please forgive me for being off topic and really off list !!!

I am trying to get a Sig100 signature pad to work with Centos 7.6 machine and am not
getting much support from the manufacturer. The product is sold as linux compatible, but
so far it is not. I have been able to download their software on a microsoft system and
see that the unit does work on microsoft.

My question to everyone on the list is have any of you had any brand of signature pad work
with Centos 7.6? If so I would surely appreciate knowing the brand and how you did it.

C7, mdadm issues

I've no idea what happened, but the box I was working on last week has a
*second* bad drive. Actually, I'm starting to wonder about that
particulare hot-swap bay.

Anyway, mdadm --detail shows /dev/sdb1 remove. I've added /dev/sdi1... but
see both /dev/sdh1 and /dev/sdi1 as spare, and have yet to find a reliable
way to make either one active.

Actually, I would have expected the linux RAID to replace a failed one
with a spare....

Clues for the poor?

How to get unrelease kernel, e.g. 3.10.0-341.el7

PXEBoot/Diskless client NFS issue

Hey CentOS list!

I've got an oddity with a diskless client setup that I suspect is the
result of the initrd.img I'm using, or some parameter I'm unaware -- or I
need to build my own initrd image (and could use some assistance on what
has to be done in that department)

Testbed is defined as:

VM A:
ip: 192.168.250.10 with dhcp server, tftp server, nfs server
VM B:
pxeboot VM, with no local disk, bios set to pxe, same internal network
as VM A
Early on in the boot cycle, it grabs a DHCP address of 192.168.250.100,
with correct mask, gw etc from VM A

C 7 and gssproxy

Ok, folks,

I brought this up some time ago, and got no replies. We have a good
number of systems - > 100 - and we use sssd. On the C 7 boxen, which is
most of them, gssproxy *frequently* (like once a day or so) dies with a
SEGV. It restarts fine. Dies again eventually.

ARE other people seeing this? If so, I guess we get to file a bug
report with upstream. Speaking as an old C programmer, dying with a
SEGV? Really? In production?

Bacula 9.4.1 Dbdriver issue

Hi list,
I created my rpm for Bacula 9.4.1 reading centos srpm spec files. I made
a single package and not split in several packages because this is my
first rpm so I created my spec file taking a cue from bacula-5.3 spec file.

All works as intended, an rpm was created and installed without any not
fixable issue.

After installing my bacula rpm I run a test to see if all works as
expected.

C7, pulseaudio, multi-user setup

Hello there,

I'm on a CentOS7 laptop, in a Mate session w/ my default user, and in
that desktop, I run apps from other users using sudo, su. It appears
that apps started using sudo or in terminals+su, can't play sound:

[pulseaudio] main.c: User-configured server at {f7ac68929370425d82f882c116a21597}unix:/run/user/1000/pulse/native, refusing to start/autospawn.

User 1000 is my default user. I've searched and read a lot about this
topic, and found many suggestions but none works so far.

What's the correct way to allow all users to play sound in my default

C7, and my RAID

Ok, I think my only choice at this point is to delete and recreate the
RAID, then restore from backup (oy, 7TB).

I see that I can do an mdadm --remove /dev/md0, then, the page I see that
on, suggests zeroing the superblocks. What would happen if I *don't* zero
the superblocks before doing an mdadm --create? Would I just wind up back
where I am?

C7 radeon driver

Hi, folks,

We've been recently (the last few months) having issues on workstations
with the radeon driver.

Re: [CentOS] C7 and mdadm - apparently SOLVED

Looking around on the Web, what I just tried was to stop the RAID, then do
an --assemble --scan, and *that* found everything, put the raid together,
and appears to be rebuilding using the new drive.

*phew*

I do find it interesting that scan works, but explicitly assembling
apparently remembers the drive that died, and wouldn't even look at it.

Inconsistent NIS Client Behavior w/ Centos 7.6

Hi All.

I am working on bringing back a number of Centos 7 rigs in our student computer lab back online. No change was made to the existing server machine [running Scientific Linux 6]

Right now there is one remaining thing to resolve: an inconsistency with the rigs' NIS Clients.

I have configured rcpbind and ypbind following guidance from Server World ( <a href="https://www.server-world.info/en/note?os=CentOS_7&amp;p=nis&amp;f=2" title="https://www.server-world.info/en/note?os=CentOS_7&amp;p=nis&amp;f=2">https://www.server-world.info/en/note?os=CentOS_7&amp;p=nis&amp;f=2</a> ) identically on all of the client machines. I have done this before with previous installs before this. The last time was this summer.

Hi

I use the Geolite legacy databases together with iptables 1.47 to filter traffic for a variety of ports and only allow .AU traffic to have access.

If I download a later version of xtables it will complain that it requires iptable>1.6 which I do not think I can get going on CentOS 6.X.

For quite some time I’ve been using FreeNAS to provide services as a NAS over ethernet and SAN over Fibre Channel to CentOS 7 servers each using their own export, not sharing the same one.

It’s time for me to replace my hardware and I have a new R720XD that I’d like to use in the same capacity but configure CentOS 7 as a Fibre Channel target rather than use FreeNAS any further.

I’m doing virtualization and this will allow me to have failover from one node to the other since they’ll all be sharing the same export rather than me simply backing up to the FreeNAS server the way I am now.

IPv6 DUID

Does anyone have a utility or method to show the IPv6 DUID for a client
system without relying on looking through a DHCP server's logs or
waiting until after a request is made?

I'd like to determine a client's DUID before I set it up for IPv6, that
way I can have it configured in the dhcpd6.conf file for a static
assignment before it gets set up.

I really don't care if it's an LL, LLT or UUID style as long as I can
get it.
