CMQ – A Swiss Army Knife for Your Mail Queue
By Sebastian Hernandez

If you use a linux based server running cPanel and you want to get the most out of it via WHM, one of the most powerful weapons in your arsenal is CMQ. CMQ is short for Configserver Mail Queues. It helps manage your mail queues.

CMQ is great if you’ve got mail that’s undelivered. It lets you retry delivery. It also helps get rid of mail that’s stuck/frozen in your mail queue that’s just wasting space. It’s also a big help if you’re running into a spam issue and want to get rid of messages sent by a specific e-mail address.

Installing CMQ is easy. Just use the following commands from a root shell:

cd /usr/local/src
wget http://configserver.net/free/cmq.tgz
tar -xzvf cmq.tgz
cd /usr/local/src/cmq
./install.sh

Once CMQ is installed you can access it via WHM. Just login to WHM and select:

1. Plugins
2. ConfigServer Mail Queues

Oh yeah, and the best part, it’s FREE!

heartbleed

Yesterday we discussed the Heartbleed OpenSSL vulnerability (aka CVE-2014-0160).  A brief how to was provided regarding patching your cPanel/WHM based server as well as your linux server indecent of cPanel/WHM.  Our technicians have been busy patching all customer servers (servers we provide as well as servers for which we provide system management services).

One thing we noticed that there was not a lot of good information for patching a debian/ubuntu based server.  In an effort to provide further information to the debian/ubuntu community, we’ve compiled a brief set of commands to help secure your debian/ubuntu based server.

All commands should be run from a root shell.

1.

user@debian-server:$ dpkg -l | grep libssl
ii libssl-dev 1.0.1-4ubuntu5.12 SSL development libraries, header files and documentation
ii libssl-doc 1.0.1-4ubuntu5.12 SSL development documentation documentation
ii libssl1.0.0 1.0.1-4ubuntu5.12 SSL shared libraries

2.

user@debian-server:$ sudo apt-get -y install openssl libssl1.0.0

3.

Restart all services that use libssl/openssl on your server. Another option is to reboot your server after the update.

Recently, a very serious vulnerability in the OpenSSL library has been found.  The bug, named Heartbleed allows the theft of information which would normally be protected by SSL/TLS encryption.  SSL/TLS is used to encrypt and secure vast amounts of data and privacy on the entire Internet.  It’s used in web, SSL certificates, e-mail, and some instant messaging clients, among other things.

The Heartbleed bug allows anyone to read the memory of systems protected by compromised versions of the OpenSSL library.  The result is compromised secret keys which can allow a malicious third party to decrypt traffic, names, passwords, and many other bits of user data traveling across links which use a compromised Open SSL library.  Basically, this issue allows attackers to view sensitive data and communications as well as to steal data directly from services.  It also allows attackers to impersonate legitimate services and users.

This vulnerability poses major problems for secure communications on the entire Internet.  To determine if your server, site, or any other sites that you may use are effected by this vulnerability, please visit this site and enter whatever URL you would like to test:

If you determine that your server is effected by this vulnerability, and you’re running cPanel/WHM there is a relatively quick way to fix your server.  cPanel has already released a patch, so be sure to take a moment to apply it.  Here’s how:

1.  Login to WHM on your server.

2.  Go to the cPanel submenu in WHM and click “Upgrade to Latest Version”

step-2

3.  Once you’re in the “Upgrade to Latest Version” section of WHM, be sure to click “Force a reinstall even if the system is up to date.”  Then click the “Click to Upgrade” button.

step-3

4.  After the upgrade process has completed, be sure to restart Apache via WHM. A more comprehensive approach would be to reboot your server completely.

step-4

*Any and all services that rely on OpenSSL should be restarted after updating.

If you’re not running cPanel/WHM on your server, the following commands issued from a root shell should do the trick:

yum update -y openssl
/etc/init.d/httpd stop
/etc/init.d/httpd start

If you still need help with this, please get in touch with our technical team.  We’ve got management solutions to help you through this issue.

Technical services provider, Total Server Solutions today announced that they have successfully transitioned away from utility power while switching to a fully renewable power source.

Gary Simat, CEO at Total Server Solutions, states “We have been paying utility companies for far too long to power our data centers. Our staff has got plenty of free time on their hands, so we’ve decided to utilize human power to keep our facilities powered up.”

Starting today, all Total Server Solutions facilities will be powered by technical staff spending their entire shift inside of a Tech Power Unit, aka human-sized hamster wheels connected to generators. In addition to powering facilities, technical staff will continue to perform their technical tasks while using specially engineered desks that levitate inside of each Tech Power Unit.

Carlos Carluccio, CIO, at Total Server Solutions says of the new power production system; “It’s a great step forward in providing power to our facilities while simultaneously giving our tech team a proper workout.”
