Hello. I desire to get bridge network working using virt-manager.



The easiest way to set up bridged networking on CentOS 7 is:

     virsh iface-bridge eth0 br0 --no-stp

This command will create a new bridge interface, br0.  The existing 
interface, eth0, will be added to the bridge, and its current IP 
configuration will be migrated to the new interface.


This is likely the coolest thing I've learned all week.  Thanks!

That file is created AFTER you've made edits, and reflects only the state 
of the file in the latest package. So it's not clear what changed from the 
original package that needs to be migrated into one's current settings.


As a rule I try to copy the original files to xxx.original so I can compare 
that to both the .rpmnew file and my working file. But I or another admin 
might forget to save the original. So I end up going the cpio route to 
extract the original files to a temp tree to do the 3-way comparison 
between the original, my modifications, and the latest package's 
modifications.

I have myself a Logitech, Inc. HD Pro Webcam C920 that I used on CentOS
6, 7 and now 8/Stream, for ~7years, and it still works great.
Detected as normal video device, so available everywhere , also used it
in google hangout/meet, bluejeans, zoom,  jitsi, etc

My only issue is that sound isn't that great, and I have video meetings
multiple times a week, so I have also a usb microphone, on a desk stand,
that I use for sound input : better sound quality during meetings

No, there is not ...
I tried initially but lack of time on my side because anaconda wasn't
able to generate an image that then would be installable on disk (never
tried since though)
Then we asked who would be volunteer and nobody showed up , so it stayed
in that state.

But , hey, welcome to OSS, if you're interested, you can make it happen
, submit patches, etc ;-)

And just to cover the lower-end of the spectrum, my Logitech C270
works fine with everything I've tried it with (cheese, skype, zoom, etc.)
On both C7 and Ubuntu 18.04.

That's quite handy! But not what I'm looking for. I'm trying to figure 
out what edits I made to my config files.


My most recent case was trying to figure out what I'd done to my BIND 
files (/etc/named.*, /etc/logrotate.d/named, /var/named/*). I ended up 
just tarring them up and erasing and re-installing the bind package, 
then untarring my old config into a tmp directory and diffing the files 
individually, reapplying appropriate changes.


Some packages make this a bit easier, such as systemd unit files (where 
my customization never touches a package file) and fail2ban (where 
customizations go in a .local file that overrides settings in a .conf 
file. I much prefer this pattern, but it doesn't work with older 
packages like BIND. Some packages have a hybrid structure with a 
directory for customizations, like apache.

You can also do a git clone of any rpm and work with the branch on your
machine:

so:

git clone https://git.centos.org/rpms/389-ds-base.git

cd 389-ds-base

git checkout c7

git log

(shows)
commit e52775ada05eb168f4b1df79fc0350b5f38d494c
Author: CentOS Sources 
Date:   Tue May 12 08:34:50 2020 -0400

import 389-ds-base-1.3.10.1-9.el7_8

commit 4c04d8bc35c01089a6ec0a234558b3637603d9e1
Author: CentOS Sources 
Date:   Tue Mar 31 05:37:27 2020 -0400

import 389-ds-base-1.3.10.1-5.el7

(and a bunch more)

If you then did:

git diff 4c04d8bc35c01089a6ec0a234558b3637603d9e1
e52775ada05eb168f4b1df79fc0350b5f38d494c > diff

then the file diff would look just like the web info you got in the link
you did in my last post.

Oh .. I misunderstood what you are after.

If you are dealing with CentOS RPMs .. you can just look at git.centos.org:

For example .. here is one CentOS Linux 7 rpm.  I'll pick 389-ds-base.


https://git.centos.org/

Click into search and type 389-ds-base .. pick rpms/389-ds-base

Click on Branches on the left tabs .. In this example, I'll pick c7

Now if you click on the left commits tab. you will see each c7 rpm import.

if you click on the six digit number, for example, e52775 for the
current latest "import 389-ds-base-1.3.10.1-9.el7_8".  The result is
every diff of every change for the rpm.

So even if you do something like 

   mail chuck

at the command line (with whatever user has a local account) it still
gets sent to the ISP?

relay_host is the host that mail is sent to if it can't be delivered
elsewhere.

relay_domains is a list of domains the host will relay mail to.

In /etc/postfix/main.cf what is 'local_recipient_maps' set to? Also,
what about 'mydestination'

If you look in /var/log/maillog what does a message log for a local
user look like when sent using the mail command?

You COULD diff the directories containing exploded source code .. but I
don't think it will help you.

These are two totally separate programs and projects.  It would be like
trying to diff GNOME and KDE because they serve the same function.  You
could technically do it, but the result would have very little meaning
as all the file names inside the code are different.  The diff would be
a copy of each file from both projects.

On an EL8 system, yum is a symlink to dnf.  So there is NO difference
between yum and dnf on EL8 (they are the exact same file .. /usr/bin/dnf).

The files for yum and dnf in /usr/bin/ are python scripts .. but they
also import many python libraries .. so they are not totally contained
in a single file.

[CentOS] Google authenticator on C8

[Patrick DERWAEL]

Hi folks

I have installed Google authenticator on a few C8 boxes
This is working fine on all of them except one...

- google-authenticator is installed and the box is added to my Android app
- /etc/pam.d/sshd contains
auth   sufficient   pam_google_authenticator.so
- /etc/ssh/sshd_config  contains ChallengeResponseAuthentication yes
- sshd restarted

When logging in, I'm prompted with the password (i.e. no request OTP
request)

I have already uninstalled/reinstalled/rebooted and compared the config
files across boxes... but I can't see what I have done wrong

Any clue about what I could have missed?

Thanks!
