Difference between "CentOS Linux 8" and "RHEL8"

I've read about all recent changes about workflow: Fedora>CentOS Stream.
I understood that in the end CentOS Linux (8) keeps on being "built from
publicly available open source source code provided by Red Hat, Inc for Red
Hat Enterprise Linux"[1]

Is that correct? I mean the only that changed are CentOS upstream (Fedora
and Centos Stream) didn't it?

Thanks in advance

keyboard is partially honored in kickstart


I'm trying to remasterize a Fedora Spin, but keyboard options is not

I've configured as follows:

keyboard --vckeymap=latam --xlayouts='latam'

The option " --vckeymap=latam" works fine. But --xlayouts='latam' is

If I boot from LiveCD, in Xorg I get:

setxkbmap -query
rules: evdev
model: pc105
layout: us

Any ideas?

Poor perfmance of bridged interfaces


I've created a bridge using 2 interfaces and have a lot of messages as

nov 12 15:30:22 localhost kernel: br0: received packet on enp0s3 with own
address as source address
nov 12 15:30:22 localhost kernel: br0: received packet on enp0s3 with own
address as source address

And the operating systems is extremely slow

Interfaces files :

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-*


NetworkManager and network service

Hi, folks,

I 've created interfaces files with the NM_CONTROLLED=no statement and I've
found that even after restarting network services changes are not commited.

Only it worked after running

nmcli connection reload

restart of the network service worked.

I wonder if it's either a feature or a bug...

Could you help me?

Thanks in advance!

Bug 3831: basic_ncsa_auth Blowfish and SHA support, really fixed?


I'm using squid-3.3.8-12.el7_0.x86_64 on CentOS 7

I've configured squid for basic authentication, md5 password *works*, but
if fails when I try to use either blowfish or sha password.

Below is the cache.log when it fails:

rndc permission denied

Hi, h when I have the following problem with rndc:

[root@centos7 ~]# rndc recursing and
rndc: 'recursing' failed: permission denied

SELinux is disables:

named.conf config file is:

// named.conf
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
// See /usr/share/doc/bind*/sample/ for example named configuration files.

options {
// listen-on port 53 {; };
listen-on port 53 {; };
// listen-on-v6 port 53 { ::1; };
directory "/var/named";

Extraneous option in sshd_config?


I've found the option in CentOS 7 in sshd_config file

#Host *.local
# CheckHostIP no

I think that option is for ssh_config, not for sshd_config. Please correct
me if I'm wrong.

Thanks in advance!

Samba as AD DC


Is (Samba) Fedora 20 still not capable of being Active Directory Domain

I mean is that page current:
<a href="" title=""></a> ?

Thanks in advance!


Hi folks,

Is able SAMBA on CentOS 7 to work as Active Directory Domain Controller? If
it's not, what is the recommended way of doing? Compiling from sources?
Install packages from SerNet?

Thanks in advance!

Half-OT: Secure boot and thirdy party kernel modules

Hi Fedora folks,

I've found that Oracle VirtualBox kernel module are not signed so I have to
disable secure boot. Oracle says that is not a VirtualBox bug. And Fedora
cannot sign it because of license, can it?

So, the question is: Is it worth signing "my own" kernel? Of course I can
circunvent this problem simply by disabling secureboot...

kdenlive and ffmpeg

Hi folks,

I am using 0.9.6 on Fedora 20 with ffmpeg-2.1.4-1.

Gui crashes when using ffmpeg

The settings of ffmpeg (Normal MPEG) are:

Code: Select all <> f=mpeg
acodec=mp2 ab=128k ar=48000 vcodec=mpeg2video minrate=0 vb=4000k

If I do the following steps

1. Go to Record Monitor tab in Clip Monitor
2. Select FFmpeg in combo box
3. Select either Video or Audio
4. Click on Record button

NetworkManager "forget" user network configurations: bug or feature?

Hi Fedora folks,

Since NetworkManager I suffer the same issue, release after release, ok,
it's not a Fedora issue

If I preserve the home partition and perform a newly installation, eg
f19->f20 NetworkManager configurations per user are lost. I think that
NM should respect the user settings and not "happily" send them to trash.

But what do you think? What is the rationale of saving user
configurations in the /etc directory?

What do you think?

hardlink command

I've found the interesting tool hardlink, supposedly it scans
directories looking for duplicates files and eventually can
consolidate them using hardlinks
Well it doesn't work for me, eg:

[sergio@madryn tmp]$ ls /tmp/test1 /tmp/test2

[sergio@madryn tmp]$ hardlink -n -v -v /tmp/

Directories 11
Objects 25
Comparisons 0
Would link 0
Would save 0

Only it works if I use the -c option:

[sergio@madryn tmp]$ hardlink -c -v -v /tmp/
Linked /tmp//alpha to /tmp//examples/alpha, saved 12
Linked /tmp//test1/alpha to /tmp//test2/alpha, saved 558

Scratch Builds

Hi folks,

Just in case, let's say we have the package foo-1.0 if I make a scratch
build of package foo-1.1, that doesn't count at all, isn't it?

I mean can I send an update foo-.1.1 completely different of the foo-1.1
sent as a scratch build, can't I?

Thanks in advance

About volatile udev directory

Hi folks,

I've found the following in Fedora 18
[root@mpinode02 sergio]# LANG=C ls /run/udev/rules.d
ls: cannot access /run/udev/rules.d: No such file or directory

I haven't found anything in the changelog about a change about it, is there
no more that directory ?

Thanks in advance!

Somewhat OT: About modules coresize


I know that is somehat OT, but I was looking for trying to discover what
does mean the size column of lsmod. Some people says is memory used by the
module, but if I run strace lsmod I found that it takes a look to coresize
files at /sys and read
/usr/share/doc/kernel-doc-3.9.2/Documentation/ABI/testing/sysfs-module and
it says "Module size in bytes" but if I see the filesize using ls don't

So what does really mean coresize?
