Re: [CentOS] Configure WiFi at install on CentOS Stream 9

Any suggestions.



I just installed CentOS Stream 9 on a workstation and hit a similar 
issue. For my situation, I did a minimal install, and in those cases, 
you may end up with a system that does not have the 
"NetworkManager-wifi" RPM (and required dependencies) installed, which 
prevents the WiFi connection from starting after the reboot. After I 
installed NetworkManager-wifi, wpa_supplicant, and a couple of other 
RPMs (manually, via RPMs on a USB device), the WiFi connection came up 
after rebooting.


Not sure if this is your scenario or not, though. I'm kind of surprised 
that this is still an issue; I believe I hit this a few years ago but 
don't have a bugzilla number for it.

I know on older CentOS systems, you could Ctrl-C and yum would move onto 
a different (hopefully faster) mirror, but now Ctrl-C just stops dnf 
altogether, and if I reissue the "dnf upgrade" command, it again slows 
down to a crawl.


Is there some setting for a minimum bandwidth threshold or some other 
way to diagnose some really slow mirror?

Can you recommend any particular command line password manager ?

Any recommendations / caveats for this kind of setup ?



I've been using "yapet" for quite awhile:  https://yapet.guengel.ch/

It's already packaged in EPEL.

The password store is in a single file so it's easy to copy between

You should be able to boot off of installation media into rescue mode,

Thoughts on what could be causing this and how could I fix it?



I'm running CentOS 8.2 on an Intel NUC, and also hit this this morning.  
The way I was able to workaround this was to copy grub2-* and shim-*

versions of those packages on the 8.2 installation media was the same as 
what I had installed immediately before this morning's upgrade.

SECOND: I LOVE CentOS. Otherwise it would not matter to

[snip]

I truly believe, Red Hat has the means to make live for the
CentOS team easier. Either by simply increasing the team,
the infrastructure to build packages faster, whatever. Or by
making the clone process easier.


IMHO this is the crux of the problem.  I feel for the CentOS team every 
time they get beat up by users asking why things take so long, and 
they're forced to explain over and over again how they have to 
re-engineer processes that the RHEL team has already engineered.


In theory, both RHEL and CentOS start from the same sources -- 
git.centos.org -- which is a great thing.  But, RHEL obviously has 
package build infrastructure, release composition, release management, 
and QA (among other) systems that are requisite steps to building and 
releasing, say, RHEL 8.2.  It makes me sad that the CentOS devs (most of 
whom are Red Hat employees, as I understand it) are forced to 
re-implement what the RHEL team has already implemented, without any 
advice, guidance, or tooling from the RHEL engineering team.  (i.e. the 
CentOS team has to discover that "these packages have to be built in 
this order, or with this modified build environment", etc. on their own)


It's not clear why 2 different groups at the same company doing the same 
thing can't combine resources.  Why can't one group at Red Hat produce 
binary RPMs from git.centos.org that find their way into both a RHEL 
compose and a CentOS compose?  And would the composes then be so 
different if the only thing that varied was the package set and branding?


Perhaps the duplication of engineering effort stems from the history of 
CentOS being a separate organization that's still undergoing integration 
with other Red Hat teams.  And I'd love to be enlightened if any or all 
of my assumptions above are wrong; my perspective is just that of a 
long-time Red Hat Linux, RHEL, Fedora, and CentOS user (since 1998 or so).

Re: [CentOS] Weird bug in 389 Directory Server : no spaces in admin console (CentOS 7)

[Greg Bailey]

Hi Niki,

Not familiar with 389-ds, but I'm curious if the admin console where the 
spaces are missing is a Java application.  If so, I encountered similar 
problems to an unrelated application I use (an older version of 
Moneydance) when there was an upgrade to OpenJDK.


If I use:
java-1.8.0-openjdk-1.8.0.222.b10-1.el7_7.x86_64.rpm (and devel, 
headless, etc.), the fonts render correctly.


Anything after that has words run together, so I'm doing "yum 
--exclude=java* upgrade" (I still haven't added an exclude for it).  
There were promising looking bugzilla entries for it, but it still looks 
broken if I upgrade.

If these packages work for others, perhaps we can revisit the idea of

There's nothing here (yet) about building MATE 1.22 (which might require

No, definitely not. I use MATE on C7, because Gnome is, how do I

Gnome-2.x wasn't broken, didn't need to be thrown away and

Not broken, but full of bugs that will never get fixed.

I did a while back rebuild the EPEL rpms for 1.20. There are spec files I could 
make available but I can't find the build environemnt setup now. It involves 
mock, a custom local repo to receive the fresh builds as you don't want to pull 
in the rpms from EPEL, and a build script that defines the order, among other 
things. If I have time next week I can try and locate everything.

I have done the hard lifting and rebuilt mate 1.22 on CentOS 7. It's not 
without quirks, and I haven't actually installed and tested, but I'm willing to 
make the srpms available - without any commitments. This might make a good 
addition to Nux :)




The person responsible for packaging the mate RPMs for EPEL offered to 
hand that off to someone, which I considered (since I'm a Fedora/EPEL 
packager), but was reluctant to offer without understanding how much 
heavy lifting was involved.  Also, I wasn't sure how much the mate on

What kind of "quirks" did you run into?

Is there however something fishy with the

dont have to try to use that horrid Gnome thing they've inflicted on us! :)



I also run MATE on CentOS 7, for the same reasons.

Only additional thing I did was to install the "nux" repo, along with 
the infinality font rpms, which drastically improved font rendering.  
For some reason, the default C7 desktop never looked as good as the 
default C6 desktop until I installed:


fontconfig-infinality-1-20120615_1.noarch
freetype-infinality-2.4.12-2.20130514_01.el7.nux.1.x86_64

In my case, I removed "cpuspeed" (rpm -e cpuspeed) before running "yum

That numbering concept (for 7.0 at least) makes sense:

"CentOS 7.0-1406 introduces a new numbering scheme that we want to 
further develop into the life of CentOS-7. The 0 component maps to the 
upstream realease, whose code this release is built from. The 1406 
component indicates the monthstamp of the code included in the release ( 
in this case, June 2014 ). By using a monthstamp we are able to respin 
and reissue updated media for things like container and cloud images, 
that are regularly refreshed, while still retaining a connection to the

Those who care about the upstream version knew that this was derived 
from RHEL 7.0.  Those who don't care about upstream versions but want to 
track monthly rebuilds of cloud images, etc., could distinguish between 
"1406" and (for example) "1407".  But somewhere along the line for 7.1, 
the "component that maps to the upstream release" was dropped, and we 
got just 7 (1503).  I don't recall seeing where or how that decision was 
made; is there a link someone can provide to the relevant discussion in 
centos-devel?

Hi Ranbir,

I've installed it on a KVM guest on a CentOS 7 host.

I haven't switched to VirtIO drivers yet except for the graphics 
(spice/QXL), so that I could resize the screen, etc.


I've always had more success using the drivers obtained from running the 
spice guest tools vs. the virtio-win stuff.  I use:


http://www.spice-space.org/download/windows/spice-guest-tools/spice-guest-tools-0.100.exe

I did have problems with blue screens at boot (to even get the

[CentOS] Unexplained size difference with CentOS 7 (1503) -01 install media

[Greg Bailey]

In the process of updating my copy of the CentOS 7 (1503) -01 install 
media, I notice that it's ~70MB larger than the image that it's replacing:


$ rsync mirrors.kernel.org::centos/7.1.1503/isos/x86_64/*DVD*.iso

-rw-r--r--  4310695936 2015/03/31 17:05:50 CentOS-7-x86_64-DVD-1503-01.iso
-rw-r--r--  4236247040 2015/03/28 12:15:26 CentOS-7-x86_64-DVD-1503.iso

But when I compare sizes using du on the mounted ISO files, I can't 
see any discernible difference:


Original CentOS 7 (1503) DVD:

$ du -ks /centos7/*
1/centos7/CentOS_BuildTag
6148/centos7/EFI

That was going to be my question as well.  According to

the convention (for the 7.0 release at least) says:

I would have assumed that this release would be 7.1.1503, and the URL 
on at least one mirror has:


http://mirror.fdcservers.net/centos/7.1.1503/

Guess if that's the new convention, I'll need to keep my ISO files 
sorted out somehow, as this progression isn't intuitive:


CentOS-7.0-1406-x86_64-DVD.iso
CentOS-7-x86_64-DVD-1503.iso

Hi Boris,

The command you want is vboxmanage

Usually I'll start a VM in the usual way (using the GUI), configure 
networking, and then shut it down.


Then, to start it headless (assuming the VM is named mytestvm1):

vboxmanage startvm mytestvm1 --type headless

Other commands that I find useful:

vboxmanage list vms
(show all the VMs defined)

vboxmanage list runningvms
(show the VMs that are running)

There's lots of other subcommands for changing configuration, etc. 
Typing just vboxmanage will show quite a bit of usage information. You 
can use vboxmanage controlvm ... to enable/disable RDP, for example.

There's not really a standard SSL certificate.  Perhaps you're

What I typically do is get a real, but free, SSL certificate from some 
place like StartSSL (www.startssl.com), and then copy the key and 
certificate to the location that's specified for use by dovecot.  That 
way, both httpd and dovecot are using the same certificate (although 
it's stored in 2 different locations).


The other thing to consider with dovecot (if you go with a third-party 
certificate) is that you may need to append the intermediate certificate 
to your server-specific certificate to properly establish the chain of 
trust for clients attempting to verify it.

So, something needs to be changed somewhere (kernel recompilation? 
missing module? wpa_supplicant / NM upgrade? stage 2 install.img?) 
which is where I'm stuck. Do I need to hack Wifi NIC related lines out 
of anaconda?


The reason that I'd like the final kernel version to be running during 
the install, is that it's needed to compile the low-level driver for a 
FIPS-140 crypto coprocessor. The target system will be an off-line 
certification authority system, and will certainly not need Wifi (in 
fact the hardening procedure foresees removal of most network hardware 
drivers).


I know I could do everything in three stages (initial install - 
software upgrade - crypto driver install); but being able to do 
everything in one go would simplify business continuity / bare metal 
recovery.


In the meantime, I'm very happy to have learned something about 
anaconda / kickstart and so on, which will be very useful in future.


If there's a quick fix to the above issues, I'd be happy to hear it.

Sounds like the Rolling media announced in:

http://lists.centos.org/pipermail/centos-announce/2014-December/020807.html

could be useful to you, although judging by the kernel version you

Unfortunately, it appears the rolling media is only available for CentOS 
7 at the moment.


Did you update modules.dep and modules.alias in the stage1 image?

Using the exact same dd command with the original CentOS ISO image produces a

I think you'd need to use the isohybrid command that's included in the 
syslinux package.  From /usr/share/doc/syslinux-4.04/isolinux.txt:


   HYBRID CD-ROM/HARD DISK MODE 

Starting in version 3.72, ISOLINUX supports a hybrid mode which can
be booted from either CD-ROM or from a device which BIOS considers a
hard disk or ZIP disk, e.g. a USB key or similar.

To enable this mode, the .iso image should be postprocessed with the
isohybrid script from the utils directory:

isohybrid filename.iso

This script creates the necessary additional information to be able to
boot in hybrid mode.  It also pads out the image to an even multiple
of 1 MB.

This image can then be copied using any raw disk writing tool (on Unix
systems, typically dd or cat) to a USB disk, or written to a
CD-ROM using standard CD burning tools.

The ISO 9660 filesystem is encapsulated in a partition (which starts
at offset zero, which may confuse some systems.)  This makes it
possible for the operating system, once booted, to use the remainder
of the device for persistent storage by creating a second partition.

 I'm trying to clarify the various ways in which I could set up

 As far as I can see there are 3 standard ways of setting this up:
1. Use amavisd
2. Use dovecot + pigeonhole/sieve
3. Use spamass-milter

 I'm not quite sure if (3) is a genuine alternative,
 or if it is why it is not the standard since it seems very simple?


I'm on CentOS 6 (well, actually Amazon AMI which is sort of somewhere in 
between CentOS 6 and CentOS 7) and I find (3) to be the easiest option:

1) From EPEL, install spamass-milter and spamass-milter-postfix RPMs

2) Modify /etc/sysconfig/spamass-milter to uncomment EXTRA_FLAGS and 
adjust spam threshold to your liking

3) Add following line to /etc/postfix/main.cf:

 smtpd_milters = unix:/var/run/spamass-milter/postfix/sock

4) Make sure spamass-milter, postfix, etc. are running and set to start 
at boot, using chkconfig, service, and/or systemctl as appropriate.

 I always just download it from virtualbox.org, also making sure to
 get the extensions package for the same veresion, also from
 virtualbox.org.

 they offer binaries for all the big linux versions, inncluding .RPM
 for RHEL/Oracle Linux, and you would use that one for Centos.

 What they don't have yet, is the guest additions for EL7. I assume
 that will become available when Oralce Linux 7 becomes available.


The guest additions should be available soon.  There's an RC of 4.3.14 
available, and so far the video driver support for an EL7 guest seems to 
work OK for me.

 Instead it prompts for password.

 I've walked through this type of scenario many times over the past few

 I think something in centos6 might be broken?

 Perhaps there is a documented step somewhere which has been added to

 The repomd.xml file has the correct names for the files, the files in this

 last one dies, we need test and build VMs around to service them.)

 I have the CentOS 3.9 *.iso files plus a local cache of RPMs against 3.9
 that is probably incomplete relative to the vault[*].

 It seems wasteful to install the last published version of the OS, then
 scp over my local update RPMs, freshen from those, *then* check with the
 vault for yet more updates.

 What I'm hoping for is some way to get a CentOS 3.10, being 3.9 with
 the vault updates directory contents merged in.

 Is there a straightforward way to do that, or is schlepping around
 folders full of RPMs actually the best way to go?


 [*] http://vault.centos.org/3.9/updates/i386/RPMS/
 If I needed to do this, I would mirror the 3.9/os/ and 3.9/updates/
 directory (and others if you need them)

 Then I would create my directory as well in the same tree or even put my
 files in 3.9/updates/ as we are no longer putting files there anyway.

 Then I would rerun createrepo on the updates/i386 and updates/x86_64
 directories and do network installs and run updates.

I used to do something similar to this, except that in this case I'd 
assume 3.9/os/ and 3.9/updates/ are static, so I'd probably combine 
the RPMS from these 2 trees together (in a subdirectory called RPMS 
for instance), and then run:

repomanage -o RPMS | xargs rm -f

so that the outdated/superseded packages would be removed from the 
collection before running createrepo.

If you have sufficient memory, I'd suggest installing VMware Player or

a guest operating system on top of that.  It's less likely that you'd 
accidentally corrupt your Windows 8 setup that way.  Some of the 
virtualization options might come in handy as well, by letting you do 
things like rolling back to a snapshot, etc., that might help you to 
repeatedly try different things without risk of having to keep 
reinstalling CentOS for each thing you want to try. I don't hear as much 
about dual boot setups these days, likely because most people just run 
both operating systems at the same time now...

Hi Johan,

 From info coreutils, section 10.1.2 (What information is listed):

  Following the file mode bits is a single character that specifies
  whether an alternate access method such as an access control list
  applies to the file.  When the character following the file mode
  bits is a space, there is no alternate access method.  When it is
  a printing character, then there is such a method.

  GNU `ls' uses a `.' character to indicate a file with an SELinux
  security context, but no other alternate access method.

  A file with any other combination of alternate access methods is
  marked with a `+' character.

My first guess would be that Machine A has SELinux disabled, but Machine 
B has (or had at some point) SELinux enabled.

The QA web site at http://qaweb.dev.centos.org/qa/blog was really 
helpful for those of us who were curious as to how CentOS 6.0 was coming 
along.  However, there doesn't seem to be much information as to how 
CentOS 6.1 is going from either the QA web site, the forums 
(Announcements), or Kananbir's twitter feed -- but it may be I'm just 
not looking in the right place.

Does the QA site only get updated once 6.1 is passed along to the QA 
members?  Wondering if 6.1 RPMs are mostly built and perhaps developers 
are wrestling with the same kinds of anaconda issues that they faced 
with 5.6...

thanks,
Greg

[CentOS] CentOS 5.6 updated packages - what about subversion?

[Greg Bailey]

I see the following in the CentOS 5.6 Release Notes:


  6.3. Packages that have been upgraded in 5.6 since the 5.5 release

* python-2.4.3-27.el5_5.3


Wouldn't subversion also be listed?

CentOS 5.5 has subversion-1.4.2-4.el5_3.1
CentOS 5.6 has subversion-1.6.11-7.el5

Is this list generated automatically or is it maintained by hand?

 Contemporary versions of git, subversion, and OpenSSH built-in. I'm
 particularly looking forward to the built-in chroot capabilities and
 GSSAPI support in OpenSSH, and the major release improvements to git

Minor point, but RHEL 5.6 finally bumped subversion to 1.6.X, so at

Check to see if you have the following file on your system:

If you do, then just loopback mount the DVD image under /media/cdrom or 
/media/cdrecorder, and then use the yum command as described in that 
repo file:

yum --disablerepo=\* --enablerepo=c4-media [command]

 Server vs. ESXi is that you can run things on the host natively if you

I would say another advantage of Server as opposed to ESXi is that you 
don't need a Windows box to administer it.  VMware Server version 1.X 
uses a server console that has Windows and Linux clients, whereas I 
believe VMware Server version 2 is web-based.  VMware ESXi *requires* 
that you have a Windows machine to install the vSphere Client.

Looks like the mirror sites still have the 5.3 updates at (for x86):

http://mirror.centos.org/centos/5.3/updates/i386/RPMS/

so I imagine you could manually edit the 
/etc/yum.repos.d/CentOS-Base.repo file and put 5.3 in there explicitly.

Usually, though, old versions like 5.3 are eventually removed from the 
regular mirror servers and moved to the vault site, where you'd be 
able to access it via:

http://vault.centos.org/5.3/

once it's moved there (not populated at present).

The CentOS (RHEL) vs. Fedora decision is easier when the RHEL version is

Friedrich Clausen wrote:
 Hello All,

 At my $WORK we have lots of in-house applications used to support the
 services we offer to customers and we deploy these to servers as RPMS.
 This works well for us except we have thousands of obsolete packages
 in our Yum repository that need to be cleaned up. What I would like to
 achieve is to keep the latest version + the last 3 revisions of a
 package and delete the older revisions.

 I was attempting to do this based on file timestamps but they are not
 reliable and in some cases packages were restored from backup in a way
 that did not preserve timestamps. So I am investigating writing a Perl
 script to do this but it is far from trivial due to the vast variety
 of version and release strings used. And there are certain situations
 in which the version strings are completely ambiguous (even to me)
 but, even if those have to be handled manually, then great time
 savings in cleaning up the rest automatically can still be achieved.

 So, before I start (re)inventing this particular wheel, I thought I
 would check with the folks on this list since I cannot be the only
 person with this problem. Are there any ready to use tools available
 to trim down an overwheight RPM repository by deleting obsolete
 packages?

 Many thanks!

 Fred.

Hi,

I've also faced this problem, and you're right:  relying on timestamps 
and/or sort order of the RPM filenames doesn't work.

The best tool I've found is repomanage.py from the yum-utils package 
available at:
http://yum.baseurl.org/download/yum-utils/

Even though yum-utils claims it needs a newer version of yum than I 
usually have, I've run the repomanage.py script that's included without 
any problems.

My typical use has been:

repomanage.py -o RPMS | xargs rm -f

where 'RPMS' is a directory with a whole mess of RPMs.  The 
repomanage.py script with '-o' as an argument spits out only obsoleted 
RPMs, so the above command removes all but the most recent version.

I see that there's a '--keep' option that *might* do what you're looking 
for (keeping the last 3 or 4 versions), but I have not used this option 
before.

Re: [CentOS] Can expect do this?

Hi all,
I'm trying to scp some files from machine1 to machine2.
But, I'm in an environment where PubKeyAuthentication is not allowed in ssh :(
So, I'm confused how to automate it as cronjob.
However, I read somewhere that we can write a little bash script that
will utilize 'expect' to answer for the ssh password prompt?
Can we do this?
Any examples are great help.
Thank you.
  


I would concur with everyone else who says you really should be using 
public keys for this sort of thing.  But, another option, if you're 
really forced to use it, is to set the SSH_ASKPASS environment variable 
to a program that spits out the password, and then ssh will use that for 
the password instead of prompting the user for it.  (See 'ssh' man page)...


Definitely not recommended, for all the reasons stated in replies to

Which completely circumvents the usual process for starting up apache,
and will be wiped away with a simple 'service httpd restart' or even
better (the weekly logrotate), and require you to reboot the machine
or call your script again.  That might not be the *best* solution.

Ian's previous post about setting variables in /etc/sysconfig/httpd is
correct. Define the vars in /etc/sysconfig/httpd, and make sure you
export them there.

This is the intended use and the 'redhat' method.
  


Also, depending on whether or not you're invoking CGI scripts, etc., you 
may need the following directive in your httpd.conf:


PassEnv LD_LIBRARY_PATH

with one or more of the environment variables you set in the 
/etc/sysconfig/httpd file mentioned above.

I used the VMware Server Console to create a Red Hat Linux VM. I also

I'm completely stuck. Can anyone help me with this?




What kernel are you running on your VMware server? (What does uname -a 
show?) You can't run the kernel-xen kernel and have VMware work; if 
that's the case, switch to the regular kernel and try that...

I can add compat-listdc++-33 when I have libstdc++-4.1.2-42.el5.i386.rpm?


Yes.  That's why the compat-* library RPMs are packaged the way they 
are; to provide applications like xten the shared libraries that are an 
older version than the default.  Most of the time, they're just .so 
files, but in the case of compat-gcc, compat-glibc, etc., Red Hat 
supplies enough compatibility glue so that applications targeted for 
version 4 can be supported on version 5, etc.

From the 5.1 release notes at:

http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.1

During the boot process you may see the message Memory for crash 
kernel (0x0 to 0x0) notwithin permissible range appear. This message 
comes from the new kdump infrastructure. It is a harmless message and 
can be safely ignored.


I wonder if this should also be included in the 5.2 release notes as a

[CentOS] How/when to file bugs on upstream bugzilla?

[Greg Bailey]

I've hit a bug since upgrading from 5.1 to 5.2 that involves the screen 
blanking when I shut the lid on a Dell Latitude D820 notebook.  It 
doesn't come back on correctly when I open the lid, and instead crashes 
X.  I've filed a bug on bugs.centos.org that describes the problem 
(#2910), and was requested to file a bug on bugzilla.redhat.com.


I've filed bugs on Red Hat's system before, but always after reproducing 
the problem using genuine RHEL.  In this case, I can't practically 
reload my notebook with RHEL 5.2, so I'm wondering how to report this 
bug to Red Hat.  I'm afraid of it getting rejected outright since it's 
not RHEL, but on the other hand I could see where the collected 
information could be useful to them if the bug report is written well...


Any advice on this?  I didn't see anything on the CentOS wiki or FAQ as 
to how or when to use upstream's bug system.


thanks!

If you have the rpmforge repository enabled, yum install id3lib.  It

Can you restore the backups, and then cp -u from the existing

the restored copy?
No.  Because all the files, changed or not since that date, are newer 
than what is on the backup.  So it would overwrite everything.





Maybe you could iterate through the file directories on your good backup 
and do a touch -r on the current set using the timestamps from the 
good backup:


foreach file in backup_dir:
  if file exists in current_dir:
 touch -r backup_dir/file current_dir/file
