Bulk TTL change in Directadmin

You may want to change TTL values for all domains and their DNS records on your Directadmin server. This can be done very easily. Here is how.

  • Go to templates directory.
    cd /usr/local/directadmin/data/templates
  • Directadmin’s default TTL value is 14400, so let’s say we want to change it to 300. You will have to edit template file named.db.
    sed -ie 's/14400/300/g' named.db
  • Rewrite all configuration files for each user
    echo "action=rewrite&value=named" >> /usr/local/directadmin/data/task.queue

Wait a minute or two, then check if user configs were rewrited with new values. Go to /etc/namedb and than open .db file of some domain. It should contain new TTL value.

Magento – Fatal error: Class Mage not found

Of corse, this can be caused by many different things, but if you’re stuck, without any ideas what could be wrong, than try solution bellow. Compiler stores everything in one file and can cause problems with includes. Just clear compiler and disable it if you don’t need it of corse.

I was getting error like this:

Warning: include(Mage.php): failed to open stream: No such file or directory in /my/web/server/root/public_html/lib/Varien/Autoload.php on line 94 Warning: include(): Failed opening 'Mage.php' for inclusion (include_path='/my/web/server/root/public_html/app/code/local:/my/web/server/root/public_html/app/code/community:/my/web/server/root/public_html/app/code/core:/my/web/server/root/public_html/lib:.:/usr/local/share/pear') in /my/web/server/root/public_html/lib/Varien/Autoload.php on line 94 Fatal error: Class 'Mage' not found in /my/web/server/root/public_html/app/code/core/Mage/Core/functions.php on line 244

Just login into your shell and then execute commands bellow (without comments):

//clear compiler
php compiler.php clear
//disable compiler
php compiler.php disable

It is most likely that this will fix your problem. If not, keep digging 🙂

Hope it helps.

Alpine PhotoTile for Instagram not showing images

If you’re using this WordPress plugin to show Instagram images gallery on your site, and you noticed that images don’t show anymore, chances are, that this is due to deprecated PHP function ereg_replace. recently I upgraded my PHP version to 7.1 and this plugin stopped working. So, if you upgraded your PHP, this is almost certain the cause of problem. There is how to fix this.

Error log was showing this:

2017/02/11 11:31:40 [error] 18865#18865: *4616 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Error: Call to undefined function ereg_replace() in /path/to/site/public_html/wp-content/plugins/alpine-photo-tile-for-instagram/gears/alpinebot-display.php:58

So, open alpinebot-display.php with your favorite text editor and go to line where error is – in this case 58. Just replace ereg_replace with preg_replace and it should work again.

Hope it hepls.

WHMCS – can’t add new tld to domains

cPanel – create directory alias on domain

Creating aliases on cpanel server is easy – for domains. But when you want to create directory alias for files outside of document root, there is no quick/click option in control panel.

Directadmin – install Letsencrypt SSL certificate on server hostname

Letsencrypt is a revolutionary step forward on web security. Free, valid SSL certificates for everyone. I won’t write about how to install and config letsencrypt on Directadmin machine. I will show only how to generate and install letsencrypt certificate on your Directadmin hostname.

When you installed Letsencrypt on Directadmin and tried to install certificate for your server hostname, there is a possibility that you came to this problem: HTTP/1.1 400 Bad Request

Just do this:

cd /usr/local/directadmin/custombuild
./build update
./build letsencrypt

And than install certificate on your server hostname:

/usr/local/directadmin/scripts/ request 4096

Open your Directadmin configuration file and change

SSL=0 to SSL=1

Also add this:


Restart your Directadmin and you should be set.

PHP: SSL operation failed with code 1

If you installed PHP 5.6 or grater and your application returns something like this:

SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL...

Then there is a simple fix for that. You can override default OpenSSL’s CA bundle with the one bellow.

  1. Download this cert bundle.
  2. Add this line to your php.ini file
  3. Restart apache/nginx and you should be ok.

check_eximailqueue: query returned no output! [FIX]

If you are icinga/nagios user and dealing with exim, you probably know for wonderful plugin check_eximailqueue. This plugin warns you when there are specific amount of email in your exim mail queue. Usually this indicates spam.

I installed this plugin on CentOS 7 with Directadmin installed. When I was executing plugin locally, it worked fine. But when I tried to execute it remotely (from Icinga server), it failed.

This was error returned when executing from Icinga server:

> # /usr/local/libexec/nagios/check_nrpe -H -c check_exim_queue
Mailqueue WARNING - query returned no output!

I added “nagios  ALL=(ALL) NOPASSWD:/usr/sbin/exim” to my /etc/sudoers file but error still persisted. I manually set Exim and sudo path in script. Error was still there.

If you check your nrpe process, you’ll see that it runs by nrpe user and not nagios!

[root@da ~]# ps -aux | grep nrpe
 nrpe 26993 0.0 0.0 46356 1460 ? Ss 10:44 0:00 /usr/sbin/nrpe -c /etc/nagios/nrpe.cfg -d

Solution is very simple. Just change “nagios ALL=(ALL) NOPASSWD:/usr/sbin/exim”  to “nrpe ALL=(ALL) NOPASSWD:/usr/sbin/exim”  in your /etc/sudoers – replace user nagios with nrpe. It should work.

I hope it helps 🙂
