Hi, folks,

   Our bastion host decided to update itself in the middle of the night,
which gave at least one user issues.

   So, the question is why?

   In both /etc/yum/yum-cron-hourly.conf and /etc/yum/yum-cron.conf,
apply_updates = no.

   Has anyone else seen this?

I can find no evidence that rpm does anything of the sort.  httpd 
restarts on upgrade because its maintainers included a command to do so 
in the %posttrans scriptlet.



Apache, for example, checks its config syntax before restarting: man
apachectl, see 'graceful' and 'restart'.


httpd checks its configuration syntax before *reloading* which is not 
what happens during an rpm upgrade.  An upgrade will run "systemctl 
try-restart", which stops and starts the service if it is running.

 Given how radically the OS changed, I would strongly advice against it.
 The move from sysvinit to systemd alone is enough to recommend against
 an upgrade.

I don't know what you should do, as I have never and would never attempt
this. Given that there are (so far failed) attempts to write an upgrade
program, I am not too confident at the chances of success.

Honestly, just stay on CentOS 6. It will be supported until 2020.

Let me offer you one option: *IF* you have enough space on your
filesystems, you could:
mkdir /boot/old /old
zsh
zmodload zsh/files
mv /boot/* /boot/old/
mv /usr  /old/
mv /lib* /old/
sync
sync
And go into the installer. If you have a problem, you can go back

Actually, I was copying part of our internal instruction checklist for
upgrading via rsync. For that, we have one machine that's been updated to
the new release. Then, on the one to be updated, we mkdir /new /boot/new,
then
rsync -HPavzx --exclude=/old --exclude=/var/log/wtmp $machine:/. /new/.
rsync -HPavzx $machine:/boot/. /boot/new/.

After doing the zsh stuff - that loads it all into memory, and it won't
gag when you do the moves, mv /boot/. /boot/old/, and /. /old, then mv
/boot/old/new/. /boot/, and /old/new/. /

Given that, you can always mv /. /old/new, and /boot/. /boot/new, rsync,
and you're back.

Is that clear as mud? The whole idea is the os and boot is moved into the
./old, and the new into the real locations.

It's good to that.  I've just tried that seven times (three different

I just started downloading
http://buildlogs.centos.org/centos/7/isos/x86_64/CentOS-7-livecd-GNOME-x86_64.iso,
one of the newer (July 2014) gnome livecd things.  Weird that the newer
ISOs seem to be broke.

Thanks to everyone to help figure out how all this works.


The newer isos work fine.  The fact that there was a key problem SOUNDS
like your Firmware has an issue with our secureboot key.  Sometimes a
firmware update fixes bad CA certs from the OEM.


I checked the BIOS firmware just a couple days ago, the latest version 
was already installed.  So the laptop out of the carton was fine.





We just released 7.1511 (based on RHEL 7.2 Sources) .. I extensively
tested the secureboot/uefi installs on 3 separate machines from 3
manufacturers (Dell, HP, Lenovo).

Download either of these ISOs (whichever one you want to use .. they all
work when doing dd to copy to a usb key and they all do secure boot):

http://isoredirect.centos.org/centos/7/isos/x86_64/

(Pick a mirror close to you)

You want one of the ISOs listed here:

http://mirror.centos.org/centos/7/isos/x86_64/sha256sum.txt

If you want to know what each ISO does, read this:

http://mirror.centos.org/centos/7/isos/x86_64/0_README.txt


It's good to have all this info  together in one  email.

On the other hand, people should know the Minimal really sucks:

up Windows.  At some point I'm going to have to recover my Windows 
install because of this install.  Every Linux install I've ever done-- 
out of hundreds of them and going back to 1992-- has gracefully and 
easily set up a dual-boot.  The README should at minimum mention that. 
Better yet, the install's name should be given "Non-dual-boot.iso".


* The resultant OS was text only.  I.e., it wouldn't run init 5... 
trying to do so would cause to hang.

Re: [CentOS] Postfix and LDAP

2015-12-15 Thread Alexander Dalloz

Am 14.12.2015 um 21:42 schrieb Ranbir:

Hi Everyone,

I thought I'd try asking here before joining the postfix mail list
since I'm running postfix on a CentOS 7 box.

I want to look up accounts via LDAP (an IPA server also on CentOS 7). I
created an "ldap_aliases" file and successfully tested it with the
postmap command: I can get the email address for an arbitrary user.
But, when I add the very same file to main.cf, I don't see anything in
the normal or debug logs for postfix that would indicate postfix is
even trying to do a ldap lookup.

Can you please provide the "postmap -q ran...@thesandhufamily.ca
ldap:/etc/postfix/ldap_aliases" call output? I guess
"ran...@thesandhufamily.ca" (from log below) is the alias and not the
result of the alias.

Here are the relevant configs:

# Virtual domains
virtual_mailbox_base = /var/spool/mail
virtual_mailbox_maps = hash:/etc/postfix/virtual_mailbox
virtual_mailbox_domains = thesandhufamily.ca
virtual_alias_maps = hash:/etc/postfix/virtual,
hash:/etc/mailman/virtual-mailman, ldap:/etc/postfix/ldap_aliases

Plain main.cf excerpts are not useful to debug a failure situation. At
least run yourself "postconf -n" to make sure that what you intend to
configure is really set for Postfix. In case this thread goes on, paste
it here.

What cannot be concluded from your config is how you achieve LMTP
delivery. virtual_transport being used?

NB: I believe I don't need to use ldap for virtual_mailbox_maps and
virtual_mailbox_domains, but I could be wrong.

Correct, you can mix different map types.

All I get is errors like this:

Dec 14 09:53:35 mailman01 postfix/lmtp[31011]: A968CC2516D:
to=, relay=10.200.5.24[10.200.5.24]:24, delay=1.1,
delays=0.78/0/0.01/0.27, dsn=5.1.1, status=bounced (host 10.200.5.24[10.200.5.24] said: 550
5.1.1 User doesn't exist: ran...@thesandhufamily.ca (in
reply to RCPT TO command))

Not your Postfix refuses the mail but the host on IP address 10.200.5.24
does that on the LMTP listener. That system, the mail storage server
does not know the mailbox "ran...@thesandhufamily.ca". So, should
"ran...@thesandhufamily.ca" exist there or should that address have been
translated by the virtual_alias_maps?

Am I supposed to enable something else in postfix to make ldap work? What I've
read about this seems to indicate I'm doing it correctly.

If the manual postmap lookup succeeds, then the map type is supported.
You can query the possible map types with "postconf -m". Postfix on
CentOS 7 is compiled agains LDAP, thus the ldap map type is supported.

Was just reading Alice's post, and it struck me a safe way would be for
the o/p to do a clean install on a different machine, then do the rsync's
I mention.

Several gotchas: don't forget to copy the old /etc/ssh/ssh_host* to the
new /etc/ssh/, check the ifcfg-, /etc/udev/rules.d/, and, if the new
system is different hardware, rebuild the initrd *before* you reboot. You
can also edit /boot/device/grub whatever the damn grub2 thing is, also
before reboot.

Or edit on the boot, get it up, and rerun grub2-install.

Thanks much for that.  I'll give that a try.  The question arises, if 
it's this easy to do by hand, why couldn't the code (if not from RH,

I can think of another example of a package restarting a service:

The glibc and glibc-common packages run a command called
/usr/sbin/glibc_post_upgrade.x86_64 or
/usr/sbin/glibc_post_upgrade.i686 (depending on whether its an x86_64
or i686 package) in their RPM postinstall scriptlet.

It runs service sshd condrestart if it detects that
/etc/rc.d/init.d/sshd exists (so, nothing on systemd-based systems).
It also runs 'telinit u' too.

I have to echo this. One of the reasons I stopped using Fedora is 
because clean installs really are the best way, even with Fedora where 
there was FedUp and related attempts, it always resulted for me in the 
new install being somewhat dirty and non-optimal.


With CentOS if you use the most recent version with your initial 
install, you have at least 5 years before you need to do it again.


And when you do need to do it again, you have time to learn the new 
system and then migrate intelligently.


If there is a version of software you need that is in CentOS 7 and not 
in CentOS 6, often you can rebuild the src.rpm and upgrade just that 
package (though sometimes it requires some spec file modifications)


I even do that with CentOS 7 where I build the latest GStreamer and 
replace the stock GStreamer1 packages.


But I wouldn't try a dist upgrade, that breaks things even on distros 
that allegedly support it. In my experience.

Nope. I want runlevel 5. As I said, I tried starting the graphical.target,
but I didn't see Xorg start.

Note that a reboot did restart it... but I should *not* have to do that.

[CentOS] Wifi Driver Broadcom BCM4322 not working with Centos 7.2

2015-12-15 Thread melkor.kp

Hi,

I've been using in the past the broadcom wifi card BCM4322 with Centos 7.1
one in the past, with kernel 3.10.0-229.7.2.el7 and driver 6_30_223_248 and
it worked well.

Now I updated Centos to 7.2 and the driver is not compiling any more under
kernel 3.10.0-327.3.1.el7. Neither driver 6_30_223_238 nor 6_30_223_271.

Does any body experienced the same issues?


Cheers,

[CentOS] Centos 6: qemu-kvm: Install guest win10 on host Centos 6

2015-12-15 Thread Dario Lesca

I have try to install from iso Windows 10 on a centos 6 + qemu/kvm, but
the guest not start and reboot after a while.

Form this page:
http://www.linux-kvm.org/page/Guest_Support_Status#Guest_Support_Status 

I understand that I must install at least qemu-kvm-2.3.0, but on the
server (up to date) is installed qemu-kvm-0.12.1.2-2.479.el6_7.2 and
there are no other updates.
I can upgrade the server to Centos 7, but on Centos7 the max newer
version of qemu-kvm is 1.5.3-105.el7_2.1

My question is: there is some way to install on Centos 6 up to date
Windows 10, or I must upgrade / install Fedora 23 server (qemu-kvm-
2.4.1-3.fc23.x86_64)

Many thanks for reply

[CentOS] Upgrade security relevant packages

2015-12-15 Thread Chris

Hello,

 

I'm looking for a solution to automatically yum update security relevant
packages on a couple hundred Centos6/7 servers. The deployment/trigger would
be Ansible.

I looked into the "yum-plugin-security" and tested it on a CentOS 6
installation but always found no security relevant updates (yum
list-security/yum --security update) where there should be at least a couple
ones. I read around it and found that this solution is not working for
CentOS (can you please confirm). What is the best practice to upgrade
security relevant packages on live systems without service interruption?

 

Thanks in advance!

 

Cheers,

Chris

I'm not sure why that wouldn't work.  I'm pretty sure you need to use a 
repository whose version matches the ISO, but that should be the case 
unless you got the netinstall ISO before 7.2 was released.


Maybe pick a specific mirror, such as 
http://mirror.sfo12.us.leaseweb.net/centos/7/os/x86_64/

(https://www.centos.org/download/mirrors/)

Any URL where you see a "repodata" directory (assuming the correct arch

In general, you don't start or restart targets; you "isolate" them,
which means 'anything that isn't in this target should stop and
anything that is should start'. You can do `systemctl isolate
multi-user.target` and then `systemctl isolate graphical.target`
(although beware that the former can and probably will kill your
session.) I guess this is reasonably analogous to doing "telinit 3" and
then "telinit 5".

In fact, "telinit 3" and then "telinit 5" should work basically as
expected under systemd -- they will isolate multi-user.target and
graphical.target, respectively.

Detecting an actual Windows install involves code that's not included in
