Re: [CentOS] C8 Questions

[Steffan Cline]

I have all my issues posted on the forum - 
https://centos.org/forums/viewtopic.php?f=54=71934

I'm using Xen and it seems to be an issue with pvgrub and grub2. No matter what 
I do, it always boots into the grubdom> prompt.

I made the changes suggested in the thread but can't get past that. HVM is fine 
but slow. PV just won't work.

 
Thank you,

I can't speak for anyone earlier in this thread, but I've had 
VMWare-hosted VMs for both RHEL 8 (originally 8.0, now 8.1) and CentOS 
8 running without difficulty.


I simply made the installation ISO visible to the VM at start time; no 
special instructions were necessary to install and re-launch the VM.


I did disable the ksmtuned service, since it does nothing but chew CPU 
on a VMWare hypervisor.

I'm really curious how you were able to virtualize CentOS 8.

What platform are you using? Xen, KVM or VMWare? PV or HVM?

I started a thread here and was referred to a project page for development. 
There was a thread on the forums for this which I replied to but it's been dead 
too so when I saw your opening sentence I'm really interested in, how'd you do 
it?

[CentOS] Cron - log when job ends?

[John Horne]

Hello,

In trying to resolve a problem with a cron job, we can see when the job starts
by looking in the /var/log/cron log file. However, I was asked if when the job
ends could also be logged. (It seems to be something that crops up every so
often over the years.)

I found on the 'net this article
https://serverfault.com/questions/248915/crontab-is-there-any-log-with-begin-and-end-time

which mentions a loglevel (-L) option, and by setting this to 2 it will log
when a cron job ends. It sounds great, and just what we could use. The downside
is that there seems to be no such option anymore. The article is several years
old but the users says they are using anacron. Checking on both a CentOS 7 and
Fedora 31 system, which both use cronie-anacron, I could find no mention of any
loglevel.

Does anyone know what happened to this option (why it was removed)? It would
seem to be useful, but removed at some time.



Thanks,

John.

You are probably looking for packages in PowerTools. Please enable
this as this will also fix your audacious problem.

Because RHEL shipped with it that way.

PowerTools is a set of packages which Red Hat ships as
CodeReadyBuilder channel fo RHEL-8. It contains packages which are not
part of the main distribution and would not have 'technical support'.
[AKA if lynx were shipped in RHEL appstream it would have certain
support levels for security and application fixes... it has few of
those in Code Ready Builder.] For CentOS it is meant to communicate
that CentOS is a rebuild of RHEL and certain problems may not get
upstream fixes.

Re: [CentOS] how to know when a system is compromised

[Leroy Tennison]

Actually, a defense here is to umount the path then remount it as a part of 
running the Aide script.  There may be an end-run to this as well- security is 
a never-ending battle.

That's not as secure as you think.  Linux bind mounts can mount a file
over another file (plus there's overlay filesystems), so it's possible
to replace a binary even on a read-only device.

Many things are available in the epel-testing repo. Even though it's marked
testing, many packages (such as openbox and rxvt-unicode are quite stable.
I would guess XFCE is available there but as I don't use it, I haven't
looked.

Again, right now, it seems that many packages are still in epel-testing.
My guess (no knowledge, just a guess) is that as CentOS-8 is relatively
new, a lot of packages still have to be made and testing.

See above.

This is part of rpmfusion, I think.  I know that when enabling rpmfusion,
CentOS users are told to also enable powertools. In the past, Nux provided
a repo for multimedia stuff, but has run out of time and can not maintain
it for CentOS-8. Therefore, one can use rpmfusion (and powertools) for
multimedia needs.

My snarky opinion is that this is what happens when single user laptop
users develop  a server O/S. You can disable it, or use nmcli (which is
like NM though, I usually disable it, though the way RH works, I imagine
that sooner or later it will be impossible to disable it and still have a
network.

I only gave my answers to some questions, I don't know the answers to the
others.

[CentOS] C8 Questions

[Alessandro Baggi]

Hi all,
I've several questions about C8. I'm using 8 on my personal NAS and 
works very well. I'm running several VMs with centos 8 and noticed 
something:


1) Why corosync, pacemaker and pcs are missing on C8? They are only 
available on rhel with payments( rhel ha addons)?
2) Why there is only Gnome as available DE? I use centos on my 
workstation and I'm a kde-plasma user. XFCE is ok but not gnome. I tried 
fedora, it has all software that I need and it is a very good distro but 
I don't like too much update and its EOL (upgrade/reinstall every 13 
months on a workstation is not so good for me). I don't want to be 
forced to install another stable distro like debian (This not means that 
debian is bad but I prefer centos).
3) I have a VM with C8 installed. I got several updates but I don't 
receive any update for 8 on centos-announce like for previous versions 
(6 & 7). Something has changed?
4) EPEL. I know that EPEL is a Fedora SIG but I use several packages 
from EPEL. There is a place to see what packages will be included in 
EPEL? For example, I tried to install audacious from epel but got errors 
for missing deps. Seems that EPEL8 is released but not ready. There is a 
ETA for this?

5) It's my impression or there are less packages in this release?
6) Why cockpit installed by default?
7) Why repo PowerTools was created? What is the main purpose?
8) Why NetworkManager is the default method to configure interfaces? I 
know that I can install network-scripts but I don't understand this change.




Best regards, Alessandro.
