OT: Problems with NextCloud 13.0.1 under Centos7

Hi all,

I have a strange problem with a clean NextCloud 13.0.1 install under
CentOS 7 (fully patched): when I try to login with admin user immediately
after setup, returns to login page without returning any error.

An no errors in nginx or php log files ...

I am using the following components:

rh-php71
rh-mariadb102
nginx 1.12

Any idea?

Many thanks.

Unbound question: forward-zone and stub-zone

Hi all,

I have a strange case with unbound ... I have defined a stub-zone to query to a secondary DNS server:

stub-zone:
name: "mydomain.org"
stub-addr: 172.22.54.4

stub-zone:
name: "54.22.172.in-addr.arpa."
stub-addr: 172.22.54.4

... but it doesn't works: any hostname or IP address is resolved. But if I use "forward":

forward-zone:
name: "mydomain.org"
forward-addr: 172.22.54.4

forward-zone:
name: "54.22.172.in-addr.arpa."
forward-addr: 172.22.54.4

all works ok.

Problems with dnscrypt's package from EPEL

Hi all,

I have installed dnscrypt's rpm package from EPEL repo under a CentOS 7.4 and using unbound as a resolver. But, I see constant timeouts and responses are very slow ... Using same config in a Debian 9 virtual machine, all works ok.

I think the problem is with dnscrypt's rpm package provided by EPEL. Anyone have seen similar problems?

Thanks.

systemd-journald errors

Hi all,

I have 5 CentOS 7 virtual guests installed (all fully patched to latest release) and i have the following error in all of them:

systemd-journald[7779]: File /run/log/journal/b4a41f4214ca44f898638301891a6f2e/system.journal corrupted or uncleanly shut down, renaming and replacing.

?? .. And I don't understand why. I have configured "Storage=volatile" in journald.conf ...

How can I debug this error? Is it possible to disable systemd-journald thoroughly?

Thanks

Error "corrupted or uncleanly shut down, renaming and replacing" in CentOS 7 clean install

Hi all,

I have installed two new CentOS 7.1708 (fully patched, kernel release is 3.10.0-693.2.2.el7.x86_64) as virtual guests, one is using lvm and the other not and both use XFS as filesystem. In both, I see the following systemd's error after a few minutes:

systemd-journald[779]: File /run/log/journal/3abe0470ce564669b797cb4c416f1ac0/system.journal corrupted or uncleanly shut down, renaming and replacing.

Is it a bug? Or do I need to change some option in journald.conf's file? Actually, I have changed Storage's option to "volatile".

Thanks.

ovirt-engine package for oVirt 4.1.x in CentOS offical mirrors disappears?

Hi all,

I am trying to install oVirt 4.1.x from centos repos but it seems
ovirt-engine doesn't exists. But instead, ovirt-hosted-engine-setup

Thanks.

Using ssd disks for kvm guests

Hi all,

Recently I have acquired a supermicro e200-8d micro server to use it as my
homelab. It is equipped with two ssd disks.

My idea is to install several kvm guests on it, but I have some doubts
about what type of filesystem (ext4 or xfs?) or block to use (lvm).

Recommendations? Do I need to accomplish some type of running if I choose
to use ext4 or xfs??

Thanks.

OT: Firefox lockdown policies for CentOS7 desktops

Hi all,

I am doing some tests with my CentOS7 desktop. I have configured a policy to lockdown Chrome/Chromium browsers and it works perfectly. And I am trying to the same for Firefox browsers but Firefox's docs are really "hard" to understand.

I have the following stopper points:

a/ what is the "real" system wide's config file: firefox.js, sysprefs.js or local-settings.js/mozilla.cfg ?
b/ And what is the real directory: "/etc/firefox", "/usr/lib/firefox/defaults/pref" or which??
c/ Is it possible to download and install addons using system wide's policy?

OT: Controlling Chrome via policy

Hi all,

I have installed Google Chrome in two CentOS7 workstations. I would like to setup some extensions by default and install automatically. Reading Chrome/Chromium docs, it is possible to accomplish this using master_preferences or via policy. According to Chromium's docs, policy files needs to be installed under /etc/opt/chrome/policies/managed/ (for Chrome) or /etc/chromium/policies/managed/ (for Chromium). I have tried to create a JSON file (custom.json) with my options, but no go.

Updating/upgrading SCL components

Hi all,

I have installed a new CentOS 7 vm fully updated. For technical reasons, I need to use MySQL 5.6.x, PHP 5.6 and NGNIX 1.x web server. To accomplish this, I have decided to use SCL components from CentOS's <a href="http://mirror.centos.org/centos/7/sclo/" title="http://mirror.centos.org/centos/7/sclo/">http://mirror.centos.org/centos/7/sclo/</a>, but I have some doubts/questions:

a/ What are the differences between rh-php56-X. and sclo-php56-X packages, for example??
b/ When these tools will be updated? .. In concrete with NGINX version. Official's NGINX stable release is 1.10.x, but in SCL repos only appears 1.8.X release .. Why?

Many thanks for your attention.

Recommendation about an usb wireless adapter to use it as HostAP

Hi all,

I would like to install/test CentOS 7.X as a hostap for my home. I am thinking to use an Alfa (<a href="http://www.alfa.com.tw" title="http://www.alfa.com.tw">http://www.alfa.com.tw</a>) usb wireless adapter or TP-Link. BUt there is not much information in Alfa's or TP-Link's web sites about which of them can run as a HostAP. If I can find any adapter that supports ac with a throughput of 150 Mbps/300Mbps, it would be great.

Any recommendation? Maybe AWUS036ACH and TP-TLW722N can supports this functionality, but I am not sure ...

Thanks.

Redhat Certificate System 9 in CentOS

Hi all,

Is RedHat Certificate System 9 based on Dogtag 9 or is it a different PKI implementation? I need to install a PKI infrastructure in my home lab to do some tests with different solutions that needs/use certificates and I have found Dogtag and RCS.

Is RCS "backported" to CentOS?? Any software recommendation to manage (administer, maintain, etc.) PKI infrastructures under CentOS??

Thanks.

Systemd spends 6 min. to startup a host

Hi all,

I have a strange behavior with a CentOS7 host (fully patched). I have
configured nics as old style format: ifcfg- ... due to I need to use
openvswitch for my vms.

All works well, except when I reboot this server. Systemd spends 6
min. to startup this host!!! .. It stops with: "A start job is running
for LSB: Raise network ...".

Are not supposed that systemd startups hosts more faster??

ok, is it possible to fix this??

Thanks.

Runing multiple daemons with systemctl

Hi all,

I am doing some tests with a CentOS7 vm image before to enter in our
production environment. I need to migrate some sysvinit scripts to
systemctl.

In all of them I need to launch some daemons in the same init script.
For example:

a) start daemon1
b) if daemon1 returns no startup errors, launch daemon2
c) if daemon1 returns any startup error, doesn't start daemon2 and exit.

Is it possible to do this with systemctl??

Thanks.

Setup a devel environment for perl modules

Hi all,

This is an interesting thread:

<a href="http://lists.centos.org/pipermail/centos/2014-April/141871.html" title="http://lists.centos.org/pipermail/centos/2014-April/141871.html">http://lists.centos.org/pipermail/centos/2014-April/141871.html</a>

about the problems you can find building perl modules for CentOS
releases (new or old).

I agree with John R. Pierce: cpan is very very bad tool ( in fact, I
hate it) to build perl modules for CentOS systems, breaks all other
perl modules. I need to use several perl modules in several servers in
my dept.
