While the SpamTitan product has been great to us for the past four and a half years, it has become less effective at filtering out spam and the per email address pricing has always been a concern. Over the past several months, we have been hard at work preparing a better solution for you.
We are very proud to announce that we are now a SpamExperts partner. Not only has our testing shown them to be superior at spam filtering, we’re confident you’ll be pleased with the pricing as well. You no longer have to worry about how many email addresses are on your domain. In place of SpamTitan’s $1.00 per user we’re offering SpamExperts at $2.00 per domain. This has resulted in a significant cost reduction for many of our clients while also offering a better service.
We completed the migration of all SpamTitan users over to SpamExperts early last week and have since opened up the service offering for all clients. A free 30 day trial is available if you would like to give it a try, just submit a ticket to request it. Additional information can be found here.
We have quite a few other ongoing projects currently so stay tuned for more updates!
cPanel’s Web Disk feature allows you to easily manage your cPanel account files beyond what can be accomplished via FTP/SFTP or the file manager. In many cases, you can even have the account’s data show up as a local folder on your computer, making it very familiar to work with. With cPanel’s free Web Desk iOS app, you can also achieve this same connectivity from your iOS devices. Once you’ve downloaded the app, you can simply add the account that you wish to connect with.
Once you’ve saved your new server, you can simply select it to connect and you’ll immediately see the data that is on the account.
This interface allows you to perform all common tasks such as downloading, uploading, renaming, creating folders, etc. from the convenience of your phone. As iOS 11 is released with the new Files app, this should prove to be even more useful. Give it a try and let us know your thoughts!
A couple years ago, we published a post on the proper configuration of SPF records when sending emails through our servers. Although not a default configuration, this is very important when you’re enforcing validation of SPF using “-all”. Due to some internal changes, the required entry has changed a little. Previously, you needed to add an A record for spf.gzo.com (+a:spf.gzo.com) and now you’ll need to simply include spf.gzo.com (+include:spf.gzo.com). A screenshot of this entered correctly in cPanel is shown below.
For those with DNS hosted by us, your SPF record has already been updated with this change. If you’re not hosting your DNS with us, the existing A record will continue to function normally in the short term, but please be sure to make the necessary change. If you have any questions or concerns, please submit a ticket and we’ll be happy to assist.
It has been a little while since we posted an update on what we’re working on behind the scenes here at Dathorn, so I wanted to take a quick moment to share. While it is easy to notice new features or see us working on your helpdesk tickets, much of our work goes completely unnoticed. That is, after all, our goal. We try to perform all updates, maintenance, etc. without any impact to your service.
While software patches and security updates are an ongoing battle, there have been a few noteworthy items as of late. You may have already heard about “Stack Clash”, a local privilege escalation vulnerability present in most Linux and BSD systems. Fortunately, we were able to quickly protect our servers against this without any service interruption, thanks to KernelCare. Traditionally, such kernel updates would require a reboot of each server but that has long been a thing of the past for us.
A few security issues have also been addressed in OpenVPN, including a remote code execution vulnerability. While serious, all of our instances were patched immediately and the severity of this particular issue for us was much lower since we only use OpenVPN internally for accessing certain private resources, such as IPMI on our servers. This had a much greater impact on VPN providers. Continue reading
Office 365 has quickly become a popular option for clients requiring Exchange hosted email. As a result, we frequently see tickets seeking help with setting up the required DNS records. Even if you’re familiar with editing DNS zones, the required SRV records may throw you off.
Microsoft does provide a general guide for all of the necessary DNS records here but it doesn’t specifically address adding them via WHM or cPanel. If you have WHM access, using the “Edit DNS Zone” link under “DNS Functions” on the left menu will be the easiest option. From there you can add the necessary records at the bottom of the page. You will have to do this in batches since there aren’t enough fields to add all of the records in at once. Once you’re done, the added records should look like this:
You’ll notice we’re using “dathornexample.com” as the domain there. Your own records will instead use your own domain. The “msXXXXXXXX” value is provided by Microsoft to verify your domain, yours will have numbers instead of the placeholder X’s. When editing DNS records via WHM, you should always put quotes around TXT values, as can be seen in the SPF record above. You’ll notice the other “MS=” TXT record doesn’t have quotes shown, that’s because they were automatically removed since they were not needed in that case. With WHM, you’re best off putting quotes around the TXT values and letting WHM decide what to do. Continue reading
Back in January, cPanel released their official iOS app and have subsequently released a few updates since then. In its current form it is still rather basic but it can be useful nonetheless. Upon running the app for the first time you’re prompted to enter server and login information for cPanel, WHM or Webmail.
You’ll notice the ability to enable TouchID. This is particularly handy so that you don’t have to re-enter login information again, you can simply use TouchID to authenticate just as many other apps already take advantage of. Unfortunately, that’s pretty much the extent of this app. When you connect to WHM you’ll see the standard web interface which is not mobile friendly. Continue reading
A rather serious Linux kernel vulnerability (CVE-2017-6074) was publicized on Wednesday (2/22). This vulnerability has been present since 2006 so it affects a large number of systems and distributions, many of which are no longer maintained. Thanks to KernelCare, our servers were all patched within a few hours of this having been published without any service impact.
If you use or manage any other Linux systems, hosting related or otherwise, you should make sure that they have been patched as well. This vulnerability could ultimately result in a local user compromising the entire system. Likewise, if you’re using devices or operating systems that aren’t being maintained and thus won’t be patched at all, now would be a good time to upgrade.
While on the topic of security updates, I do also want to mention the critical WordPress 4.7.2 update that was released about a month ago. If you are running WordPress 4.7 and have some how managed to not upgrade to 4.7.2 by now, you should do so immediately.
As always, we will continue to stay on top of these security updates, keeping you safe and informed.
There’s been a lot happening here under the radar over the past month, so this gives us a great opportunity to post another of our “Behind the Scenes” updates. To start, we completed migration of all remaining CentOS 5 servers due to its end of life date, March 31st, quickly approaching. One of these servers was our primary DNS server (ns1) which was seamlessly migrated to a new CentOS 7 server without any service interruption.
CloudLinux’s LVE Stats 2 made its way out in a stable release, completely overhauling how system resource usage data is recorded on our servers. CPU and RAM usage is now recorded with much greater precision but perhaps most important is the new snapshot functionality. Now, when a CPU or RAM usage fault occurs, a snapshot of the account’s running processes is recorded. This allows you to go back and see what was running when a fault occurred, which is very helpful in identifying what caused it. Previously, no such information was available unless you actively witnessed the fault occurring.
PHP 7.1 was officially released and shortly thereafter available on all of our servers via CloudLinux’s PHP Selector. Our servers now offer PHP versions 5.4, 5.5, 5.6, 7.0 and 7.1. Version 5.6 is the default on new cPanel accounts and this can easily be changed via the “Select PHP Version” link in cPanel. Continue reading
Although the PHPMailer vulnerability was posted to our Script Security Forum a couple days ago, the widespread and critical nature of these warrants a post here as well. PHPMailer and SwiftMailer are both libraries used for sending emails. A very large number of scripts use one of these two libraries, including WordPress, Drupal, SugarCRM, Joomla and many others. Both libraries contain similar remote code execution vulnerabilities that can be exploited under certain circumstances.
It is very important that you make sure all instances of these libraries are updated. This will, unfortunately, be difficult to pinpoint in some cases since many plugins also include these libraries. Every core script, plugin and theme that you use should be investigated to determine whether or not these libraries are included and require updating.
All instances of PHPMailer must be updated to 5.2.21 or higher, which can be downloaded here.
All instances of SwiftMailer must be updated to 5.4.5 or higher, which can be downloaded here.
This would also be a good time to examine your plugins and themes to make sure they are all being actively maintained. As a general rule, if they haven’t received any updates within 6 months you should be concerned. If they haven’t received any updates within the past year, they probably shouldn’t be used at all.
The ongoing use of abandoned projects are one of the bigger risks that face websites like those powered by WordPress. While such a plugin may appear to be all good and up-to-date from within the WordPress admin panel, the developers may not have touched it in years and the project page may no longer even exist. As such, a regular audit of these is a very good idea and in general you should stick to more popular options when possible.
If you run into any issues with updating or have any questions please feel free to post a comment here, post on our forums or submit a ticket via our portal.
We’re excited to announce that two-factor (2FA) authentication is now available for all of our cPanel and WHM users! Two factor authentication adds an additional layer of security to your logins by requiring a security code in addition to your username and password to login. This security code is provided by an application on your mobile device once setup on your account.
WHM users can find the “Two-Factor Authentication” link on the left menu under the “Security Center” as seen below.
On this page you can go to the “Manage Users” tab to view and modify any cPanel users under your reseller account that have 2FA enabled. You can also go to the “Manage My Account” tab to setup 2FA on your own WHM account. Continue reading
