sendmail on Centos 7.7

Hi All,

I am 'trying' to set SMART_HOST in sendmail to point to smtp-relay.gmail.com
but when looking at the /var/log/maillog its going to mx203.inbound-mx.net.
[192.110.255.243],

why???

my line from sendmail.mc
define(`SMART_HOST', `smtp-relay.gmail.com')
I did make in /etc/mail and service sendmail restart

This is the only SMART_HOST in the config file. I started with the default
CentOS 7.7 sendmail.mc and have not added anything else.

Mirroring two screens for all users?

We would like to have one workstation (CentOS7 with Gnome3) set up that

The workstation is using an Nvidia (proprietary) driver for the graphics

C8 and NetworkManager problem

Hi list,

I've installed C8 on my workstation. I configured my network devices
(two bridges, two nics) using nmcli. Now that NM is the default I tried
it. On C7 I always disabled it.

I noticed some problem:

1) During the boot, also if NetworkManager-wait-online.service status is
OK, I noticed that opening a terminal and ping some address it needs
some time to perform ping and any operation on a network connection. So
seems that in the first 30sec/1min there isn't an available network
connection.

qemu-kvm

I am running this command
/usr/libexec/qemu-kvm -no-acpi -smp 4 -m 2048 -drive
file=myimg.img,format=raw -vga std -device rtl8139

and expecting a window to open up for the console. It does not. This is on
CentOS 8.
Do I have something missing/not installed - or something wrong on the
command line.

Virtualizing on CentOS 8

I am trying to get going with CentOS 8.

In the past I would run qemu-system-x86_64 -hda myfile.img
get a console and off we go.

I dont with to use virt-manager and the gui and all - I just wish to have a
similar
command line to boot up and run my img.
Is there something like that I'm not finding ?

I have found virsh - but I dont see how to make it run with an image file
from the command line. Perhaps I'm missing something.

Thanks,

can't login as subsequent FreeIPA users

When I set up a machine with CentOS 8, I used the "Enterprise Login" in
the initial setup wizard to authenticate against my FreeIPA server.
This worked fine, and I have no issues logging in with that initial user.

However, I am unable to use GDM or the console to login as any *other*
valid user from FreeIPA. From GDM I get something like "Sorry, that
didn't work" and "Permission denied" on the console. I've verified that
the credentials are correct, and that I am able to manually get a ticket
via kinit for one of those other users from this machine.

Re: [CentOS] Firefox 68 jnlp files

icedtea-web package included with the distros is the plugin that handles javaws for firefox for both RHEL/CentOS 6 and 7 and openjdk. I have yet to find an app that cannot use openjdk instead of oracle java. It may be a little less streamlined, but it's functional. Ignore/cancel any pop ups that talk about updating java.

If I missed this answer, I apologize as I receive the digests.

Post-installation setup script for CentOS 7 servers

Cron - log when job ends?

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
<a href="https://serverfault.com/questions/248915/crontab-is-there-any-log-with-begin-and-end-time" title="https://serverfault.com/questions/248915/crontab-is-there-any-log-with-begin-and-end-time">https://serverfault.com/questions/248915/crontab-is-there-any-log-with-b...</a>

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.

C8 Questions

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.

how to know when a system is compromised

How do you know when a Linux system has been compromised? 

Every day I watch our systems with all the typical tools, ps, top, who,
I watch firewall / IPS logs, I have logwatch setup and mailing daily
summaries to me and I dive deeper into logs if something looks suspicious.

What am I missing or not looking at that you security gurus are looking at?

I subscribe to the centos and SANS newsletters, and I try to keep
current on all technology with credible sources of articles online and
with the Lynda library.

What other sources of information do you use to stay current about the

About license at redistribution

Hello.

I'd like to ask about license issue.
Now I'm planning to make and sell some measurement system controlled by PC.
There is no technical issue but I don't have enough information about
license.

I will do the following,

1) Install CentOS and my applications on the PC.
2) Sell the PC as a measurement device.
3) Distribute DVD made from CentOS iso image file to the user if he/she
needs.

Question 1.
Is there no problem from the view point of CentOS license ?

Question 2.
Should I donate to CentOS community ?

Best Regards.

Centos 8 server rebooting...

Can someone provide some guidance with my server, I have a fairly new
centos 8 server, pretty much just a KVM host but I have noticed that its
dumping and rebooting at various times. Journalctl does not go back past
the reboot so I am unable to catch what may be causing it, it appears to be
KVM from /var/log/messages and it appears I should have a kernel dump file
but I am unable to find it.

How can I monitor if there is actually disk i/o to warrant this constant

So noatime for all partitions work with XFS?  I did some browsing and
the claim is XFS uses realtime which is better?

Need help modding src.rpms to generate complete SAMBA AD DC binary RPMs for CentOS 8

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.

printer only prints one page, if anything

I've got a Brother HL-L2360D series printer connected to Centos 7.
CUPS lists it as Generic PCL6/PCL Printer - CUPS+Gutenprint v5.2.9 .
When I tell it to print a pdf file, it prints at most the first page.

After powering the thing off and turning it on again,
it printed page 3 of pages 3-6 .
On trying it again, the thing claimed it was receiving data
and printed page 3 of pages 3-6 again.

I've tried to delete the printer so I could add it again,
but CUPS won't let me.
CUPS quit asking for a password, it just says Forbidden.

How do I print the pdf file?

workstations which use the exported file systems for /home. I have an
external drive connected via USB (/dev/sde) and mounted on /rsnapshot. I
use rsnapshot to back up the RAID5 to the external drive periodically. I
also export /rsnapshot (read only) to the workstations so users can grab a
backup copy of /home data if needed.

udev on CEntOS7 - can't get a match, looking for tips...

The mtx binary requires my tape library to be assigned a sg# driver, but
the kernel periodically renumbers the sg devices. Normally, we would
write a udev rule to manually assign a persistent name, but it looks
like things have changed as I can't seem to get a match on CEntOS7. I'd
appreciate any feedback or pointers to help me get my rule working.

HA tools from clusterlabs.org

hi everybody,

would you know if 8 version is going to have HA solutions from
clusterlabs.org available, just like Centos7 has? (from Centos' own
repos/streams)

many thanks, L.
