xfs quota question

Can I go to an existing xfs file system, and apply a soft quota to each
user on it? If I do, can I then run a report, and see who's using how
much, or does it only apply to files created after the quotas are applied?

bad udp cksum

Hi,

Recently I'm noticing an interesting issue.
My CentOS servers are trying to send logs to a logging server via 514/udp,
however I'm not receiving anything.

I did the following on CentOS
*tcpdump -vvv -nn udp -i esn160 port 514*

In another session on the same server:
*nc syslog-server -u 514*

tcpdump started to show me messages like:
*[bad udp cksum 0x3ce9 -> 0xb0f5!] SYSLOG, length: 172*

After some research I disabled TCO (ethtool -K ens160 tx off rx off), now
tcpdump shows:
*[udp sum ok] [|syslog]*
And I'm also receiving the logs.

Can't boot into GUI: Centos 7 "Server with GUI" option

I'm setting up a new server on Centos 7, running x86_64. Motherboard is a MITAC PD11BICC, running
Indian Bay Trail, with a i915 chipset.

I installed "Server with GUI", but when it boots I get the "blank screen with a cursor" issue.

Decided to see about disabling the i915 driver, by blacklisting it. but I don't think I have the
right commands, as when I did that, it appeared on the reboot the i915 driver was still active.

vi /etc/modprobe.d/blacklist_i915.conf
added the following line to that file
blacklist i915
Saved the file.

Okular

Does anyone know what Magical configuration file determines whether okular

Centos 7.5..and My GDM Greeter/GDM Don't Work Anymore

So, we've updated to 7.5, and for two machines--A Dell Precision M4800,
and a Dell Precision 7510..both running Radeon cards--we no longer get
the GDM Greeter login box NOR can we switch to virtual text login
terminals. It's been driving me nuts. The systems do allow for SSH
logins, so that's how we get to them, but I've checked the Xorg.0.log
and nothing stands out.

systemd equivalent of xinetd 'only_from' and 'banner_fail' attributes

I'm attempting to port an existing xinetd service from CentOS 6 to
something equivalent with systemd for CentOS 7

The existing xinetd config uses the attributes 'only_from' to limit
connections from a limited set of remote hosts and 'banner_fail' to
print a suitable error message when access is denied

However, I can't find suitable 'equivalents' with systemd socket/service
files on CentOS 7

It appears later versions of systemd supports the option IPAddressAllow=
(which is what I think I need ?)

Does anyone know how to limit the remote hosts that can connect to a
port with CentOS 7's

Back to Xfce

Now that the basic server is up and running.  With Gnome via VNC (yuck),
it is time to go back and figure out howto install Xfce without an Xfce
group script.  So I am asking those with X64 Centos for some pointers. 
Like where are the group scripts so maybe I can modify them for armhfp.

I was reading:
<a href="https://www.rootusers.com/how-to-install-xfce-gui-in-centos-7-linux/" title="https://www.rootusers.com/how-to-install-xfce-gui-in-centos-7-linux/">https://www.rootusers.com/how-to-install-xfce-gui-in-centos-7-linux/</a>

Where the author talks about doing a minimal install then running:

yum groupinstall "Server with GUI"

But notes that this installs Gnome (which I don't want) and that instead to

yum groupinstall “X Window System”

How do I actaully get the current sources from centos-git?

Hi,

I am trying to retrieve the srpm for the latest centos-release pacakge
from centos-git by following the instructions @ <a href="https://wiki.centos.org/Sources" title="https://wiki.centos.org/Sources">https://wiki.centos.org/Sources</a>.

If I run the following commands:
git clone <a href="https://git.centos.org/git/rpms/centos-release.git" title="https://git.centos.org/git/rpms/centos-release.git">https://git.centos.org/git/rpms/centos-release.git</a>
cd centos-release/
git checkout c7

Everything completes without error. The problem is that the sources that get
downloaded are not for 1804.

SSSD and cache persistence

I have a large number of CentOS machines (both 6 & 7) getting account

Installing GCC 5.3.0 in CentOS 6 in Docker.

I need to compile some C++ 11 with GCC 5.3.0 on CentOS 6. All of this
is happening inside docker in CI using the centos:6 base image. (NB.
It can't be GCC 6 or 7, because I have to send binaries to clients who
won't install newer vs of libstdc++.so.)

Until recently, I was installing devtoolset-4-gcc-c++ via yum, and then using

RUN scl enable devtoolset-4 gcc

to build the code.

Lenovo Ideapad 320 touchpad not recognized

I'm setting up a new Lenovo Ideapad 320 and everything shows up and works fine except for the touchpad.

I did have to get into the bios and set Legacy for boot device and boot mode to get Centos 7 to finish installing. The default bios settings would load the Centos 7 Gnome Live image from a usb flash drive and work (except for the touchpad) but when I tried to install to the hard drive it would get to the end of the process and kernel panic when it was writing the bootloader.

rsync versioning problem

I seem to have an rsync versioning problem.

The sender is an old ClearOS6 server with rsynv 3.0.6
The receiver is a brand new Centos7-armv7 server with rsync 3.1.2

I am running rsync over ssh

Got the error:

rsync error: error in rsync protocol data stream (code 12) at io.c(600)
[sender=3.0.6]

And researching this it comes down to a versioning issue.  But all I
have found was to upgrade the 3.0.6 system!  That will happen when I
migrate to ClearOS7!

Is there some option to specify to get this to work?

rsync -ah --stats --delete -e "ssh" /var/flexshare/shares

How to set macaddr with nmcli

I see my problem.  I mis-read what

nmcli con mod eth0 mac "02:67:15:00:81:0B"

does.  It sets HWADDR; which interface to link to, not MACADDR, what MAC
address you want for your interface.

So I have read the nmcli pages and googled a bit.  I cannot find a way
to set MACADDR.  I suppose I can set HWADDR then use sed to change it to
MACADDR, but this seems a real hack.

ARM boards do not have assigned MAC addresses.  Uboot uses various
information to generate a local MAC address.  I want finer control of my
MAC address for my servers.  In the past, I just edited ifcfg-eth0.  I

Why the new centos-release update?

Just curious about this after seeing the following output of a typical
"yum upgrade":

Resolving Dependencies
--> Running transaction check
---> Package centos-release.x86_64 0:7-5.1804.el7.centos.2 will be updated
---> Package centos-release.x86_64 0:7-5.1804.1.el7.centos will be an update
...etc...

After downloading the 2 centos-release RPMs, the content appears
identical.  I was assuming there'd at least be differences with yum
definitions, GPG keys, or something like that.

Was it just to fix some naming inconsistency or something?

ifcfg-link?

This is happening with the Centos7-armv7 image 1804, but I was wondering
if it is a broader C7 issue.

My image has only 2 ifcfg files:  ifcfg-l0 and -link.  'ip a' is listing
the ethernet as eth0.  ifcfg-link has contains:

DEVICE=link
BOOTPROTO=dhcp
ONBOOT=on

I then used nmcli to create my ifcfg-eth0

nmcli con delete eth0
nmcli con add type ethernet con-name eth0 ifname eth0 ip4
192.168.129.11/25 gw4 192.168.129.1

NFS/RDMA connection closed

Hi, we are having a problem with NFS using RDMA protocol over our FDR10
Infiniband network. I previously wrote to NFS mailing list about this,
so you may find our discussion there. I have taken some load off the
server which was using NFS for backups, and converted it to use SSH, but
we are still having critical problems with NFS clients losing connection
to the server, causing the clients to hang and needing a reboot. I
wanted to check in here before filing a bug with CentOS.

Our setup is a cluster with one head node (NFS server) and 9 compute
nodes (NFS clients).

Screensavers on Centos-7

Hi all!

I keep having problems with screensaver(s) on Centos-7.

I have in the past liked Xscreensaver, so I've installed it and tried
to suppress whatever other screensaver is on the system. Xscreensaver
works fine for a day or 20 then quits working. After a lengthy battle
I gave up and removed it.

I'm now trying mate-screensaver, which does the same thing!

when I say "quits working" I mean just that. one night it goes to a
black screen (as configured) then a minute or two later the power manager
shuts off the screen.

Finding user's files

This is among the things we need to do when a user leaves, and it's a
larger question than it sounds. Our Office has many servers, with a good
number of fileservers for projects, with large filesystems (i.e. 10's of
TB).

Strange vncserver behavior

I got vncserver working per:

Then I went to set up a second instance, and have that for logging on to
root:

==========

cp /lib/systemd/system/vncserver@.service
/etc/systemd/system/vncserver@:2.service

vi /etc/systemd/system/vncserver@\:2.service

replace <USER> with root

systemctl daemon-reload
systemctl start vncserver@:2

==========

I got the message:

Job for vncserver@:2.service failed because a configured resource limit
was exceeded.

C7 Xfce group

I am working with Centos-arm which right now only has the gnome and kde
desktops.

I am spoiled with using Xfce on all my Fedora systems (MUCH longer
battery life on my notebook, for example).  I like its simplicity.

I see from messages here that mainline C7 does have the Xfce desktop.

Can someone give me a list of rpms that make up the group, so I can try
starting with the minimal image and see if I can build an Xfce desktop?

Meanwhile I am going to put in a request for Xfce on the centos-arm list.

thanks

ecryptfs (from centosplus) and libvirt lxc quest on it - quest upon start shoots host in the head

hi guys

I have a lxc guest on Dell's R815(AMD Opterons) which I just moved to an
ecryptfs mounted folder(using centosplus' kernel)

Copying data to that folder seems to work just fine, but I as soon as I
start the quest the host gets shot in the head, hard reboot, no dump.

I also have another, virtually identical guest but on Intel platform and
that one does not do anything but runs okey.

Any of you guys has experience such gross abnormality?

many thanks, L.

Xfce vs. VirtualBox : font size problem

Hi,

I'm running CentOS 7 with Xfce on my main workstation. I just installed
VirtualBox, and the application is running nicely. The only problem is
that VirtualBox fonts are too tiny. How can I make the application
behave and use the system-wide font settings ?

Increase Disk Space with LVM

Dear CentOS-Community,

we have a server with four hard drives that are configured as raid10
(/dev/sda).

Now, /home and /root are almost full. Therefore, we decided to buy four

additional hard drives that should configured also as raid 10 (/dev/sdb).

I want to use LVM to extend disk space for root and home.

My (successful) test procedure in a virtual environment looks like this:

1. devide /dev/sdb into /dev/sdb1 for root and /dev/sdb2 for home using
parted
2. Convert disk to physical volume: pvcreate /dev/sdb1

Issues booting centos7 [dracut is failing to enable centos/root, centos/swap LVs]

Hello,

I'm having a strange problem booting a new centos7 installation. Below some
background on this. [I have attached the tech details at the bottom of this
message]

I started a new CentOS7 installation on a VM, so far all good, o/s boots
fine. Then I decided to increase VM disk size (initially was 10G) to 13G.
Powered off the VM, increased the vhd via the hypervisor, booted from
CentOS livecd, selected "recover my centos installation". Then I used the
following sequence of commands to make the new vhd size "visible" to the
o/s ...

- ran fdisk /dev/sda and deleted partition 2.

Finding memory usage

I have a CentOS 7 server that is running out of memory and I can't
figure out why.

Running "free -h" gives me this:
              total        used        free      shared  buff/cache  
available
Mem:           3.4G        2.4G        123M        5.9M       
928M        626M
Swap:          1.9G        294M        1.6G

The problem is that I can't find 2.4G of usage.  If I look at resident
memory usage using "top", the top 5 processes are using a total of
390M.  The next highest process is using 8M.  For simplicity, if I
assume the other 168 processes are all using 8M (which is WAY too high),

SCLO: Clang 5 package

Hi, a new version of llvm toolset was released on RHEL including clang 5
several months ago:

<a href="https://developers.redhat.com/blog/2018/05/03/announcing-ga-for-latest-software-collections-developer-toolset-compilers/" title="https://developers.redhat.com/blog/2018/05/03/announcing-ga-for-latest-software-collections-developer-toolset-compilers/">https://developers.redhat.com/blog/2018/05/03/announcing-ga-for-latest-s...</a>

devtoolset 7.1 (gcc 7.3) was announced around the same time and has been in
CentOS sclo repo for some time now, but still no sign of clang 5.

Is this on anyone's to do list? llvm toolset contains a really convenient
version of clang / clang-format, which I believe many developers are using
daily for various tools.

FF60 does not allow download to ssh/davs

Hello All,

this concerns fully updated Centos7 / Mate machines;
I have people connect to ssh en davs locations. In /home/user/.gtk-bookmarks I put entries like
ssh://192.168.1.8/data data-remote

People can then click on the bookmark in the file manager and connect to it.

Since FF60 people can no longer save files for instance from their mailbox to these "mounted" locations. Before, when choosing "save as", the mounted ssh location would
appear in the download window.

I guess this is not a bug but something one can disable/enable in about:config.

Is there any way I can deploy cPanel web hosting control panel with Microsoft Exchange 2016 groupware behind one static public IP?

Good evening from Singapore,

Is there any way I can deploy cPanel web hosting control panel with Microsoft Exchange 2016 groupware behind one static public IP? Or do I need 2 static public IP addresses at the minimum? With Exchange 2016 groupware taking up HTTP, HTTPS, IMAP, IMAPS, POP3, POP3S, SMTP, and SMTP/S ports, I personally don't think I can deploy cPanel behind the same public IP as Exchange.

Please advise. Perhaps you have a brilliant idea.

Logwatch inconsistency

Hi all,
In my logwatch config I clearly state only too report on Yesterday.
The funny thing is that in the MailScanner section the number of mails
scanned is different thant th number reported in the postfix section to
be put on hold.
Ik I grep the Requeue statements in the MailScanner logfile this is
exactly the same number as the scan result of Hold in the postfix
logfile and is equal to the number reported by logwatch in the
MailScanner section.
How come postfix reports a lot more being put on hold than the real
number?
There is at least some inconsistency in there.

Which is better? Microsoft Exchange 2016 or Linux-based SMTP Servers?

Good evening from Singapore,

I am torn between deploying Microsoft Exchange 2016 and Linux-based
SMTP servers like sendmail, postfix, qmail and exim.

Relative ease of installation and configuration is an important
consideration factor.

Microsoft Exchange 2016, Domain Controller, and Active Directory are
relatively easy to install and configure. Linux-based SMTP servers are
extremely difficult to install and configure and of course, extremely
time-consuming.

One of the features of Microsoft Exchange 2016 is that you can create
additional folders on your Inbox in the server (server-side).

Panic with EL7 KVM guest on EL6 host on AMD server with latest kernel

Hi,

I have AMD servers running CentOS 6.10 as KVM host and on it guests
running CentOS 7.5.

Since the latest kernel update on CentOS 6.10,
kernel-2.6.32-754.2.1.el6.x86_64, I can't boot the CentOS 7.5 guests with
kernel-3.10.0-862.6.3.el7.x86_64 anymore.

Reverting CentOS 6.10 host to kernel-2.6.32-754.el6.x86_64 fixes the problem.

Screendump of the panic is attached, not very helpful I guess.

The CPU models where I could test it are:

cpu family : 15
model : 65
model name : Dual-Core AMD Opteron(tm) Processor 2218
stepping : 3

cpu family : 16
model : 6
model name : A

FF 60.1 can't print pages to files...

Yet another issue with this new browser.

If I look at a web page and try to print it to a file, FF crashes.
CentOS 6.10

Going back to FF 52.8. This new version is just unworkable for me.

Font related problems with recent FF 60.1

When I start FF from command line, I'm getting a lot of errors similar to
these --

Firefox 60 crashes when trying to save an image

On any web page with an image, if i right-click on the image and select "Save Image As...", firefox crashes.

Final messages from stderr:
(firefox:3401): GLib-GIO-ERROR **: No GSettings schemas are installed on the system
[Child 3502, Chrome_ChildThread] WARNING: pipe error (3): Connection reset by peer: file /builddir/build/BUILD/firefox-60.1.0/ipc/chromium/src/chrome/common/ipc_channel_posix.cc, line 353

I've reported this on RHEL bugzilla (1601254), but on the off chance that this is a problem with the CentOS build I'm posting here as well.

Centos 7 Not coming back from Sleep

Hi All

im running centos 7 on my HP Probook 450. the problem im having is that
when i put the Laptop to sleep (close the lid or press power button

lights up the keybord LED's to indicate PC is awake, but the screen will
be blank. i have  to force reboot ( long press of power button) for the 
laptop to come back up.

kvm & permission denied

Everyone,

I am trying to install KVM on a desktop unit as a lab project with the
hope of being able to use kvm on one of our office servers after I
learn how. So far I am very low on the learning curve.

I have used the guide to make the installation :

<a href="https://www.linuxtechi.com/install-kvm-hypervisor-on-centos-7-and-rhel-" title="https://www.linuxtechi.com/install-kvm-hypervisor-on-centos-7-and-rhel-">https://www.linuxtechi.com/install-kvm-hypervisor-on-centos-7-and-rhel-</a>
7/

The installation seemed to go well, but when I tried to add Fedora 27
with virt-manager I have continued to get file permission errors.

Clamd issues on Centos 6.10

Hello all,

Been having an issue today that I can't seem to solve, so reaching out to others much more
knowledgeable for help/advice/assistance.

I ran the software update this morning and installed 134 packages, clamd was one of the packages.
Upon completion of the update, I needed to reboot the box.

ssm vs. lvm: moving physical drives and volume group to another system

I did the following test:

###############################################
1.

Computer with Centos 7.5 installed on hard drive /dev/sda.

Added two hard drives to the computer: /dev/sdb and /dev/sdc.

Created a new logical volume in RAID-1 using RedHat System Storage Manager:

ssm create --fstype xfs -r 1 /dev/sdb /dev/sdc /mnt/data

Everything works.
/dev/lvm_pool/lvol001 is mounted to /mnt/data.
Files and folders can be copied/moved, read/written on /mnt/data.

###############################################

2.

I erased CentOS 7.5 from /dev/sda.
Wrote zeros to /dev/sda using dd.
Reinstall
