How to dispute patched CVE-2024-6387 on AlmaLinux9

If your server is being scanned by security software that software may very well tell you that you have a security vulnerability with regards to the SSHD version. Specifically it may say that your server is vulnerable to CVE-2024-6387. Here’s what we’ve done for our Brownrice SmartVPS hosting customers and how you would dispute this vulnerability if you are one of our customers.

First, none of our SmartVPS’s are vulnerable to CVE-2024-6387, we patched this on everything that was vulnerable across our systems less than a week after the vulnerability was announced and the patch was released.

Proxmox Mail Gateway

Proxmox Mail GatewayWe’re converting our first-layer of spam protection from straight spamassassin gateways to Proxmox Mail Gateways and I’ve gotta say, the conversion has been magically easy and results have fantastically pleasing. We use these gateways to pre-scan all incoming email for spam and viruses before passing those emails on to our email customers.

Proxmox Mail Gateway uses a wide variety of local and network tests to identify spam mail. Here is a short list of used filtering methods:

Upstream pipes, sorted!

Yesterday, September 14th, 2023, Lumen rerouted one of our internet pipes so that there are longer any overlapping areas where both of our outgoing fiber connections are physically near each other.

Additionally, the morning before, on September 13th, 2023, we successfully completed our final failover tests on our new, third outgoing pipe, which is wireless for the first 1/2 mile, then takes another fully diverse fiber path to the internet.

This completes the network changes that will ensure that the dual-fiber cut that happened on June 7th of this year can not happen again. Additionally, even if both primary fiber connections were to be taken down in some wildly bizarre way, we’ve now got a third connection that all of our traffic will route through, with no slowdown in performance.

We thank Lumen and Kit Carson Internet for working with us to make this all happen. It’s kind of a big deal for us.

Now running AlmaLinux 9

We’ve loved you for many long-times CentOS, but we’ve moved on… And, well, its you, not us.

And Hello AlmaLinux 9!

CentOS was very good to us for decades of solid and fast hosting. In fact we built our entire hosting business off of it. However, when CentOS switched to stream-based updates we decided we had to start looking at other Linux operating systems for our hosting base.

We won’t bore you with the details of this search but know that of mid-June all of our new SmartVPS servers ride on the back of AlmaLinux 9. The transition has been surprisingly smooth and the results have been fantastic! We’re seeing considerable speed increases and much improved memory management throughout our hosting stack.

So moving forward, we’re riding with AlmaLinux!

2023 Brownrice Internet News

It was a heckuva busy pandemic for us here at Brownrice and we thought you might be interested in some of the things that we’ve been doing behind the scenes to ensure that your web sites, webcams, email, and servers are serving up the things they serve quickly, securely, and reliably!

Data Center Upgrades

During the pandemic we grew at unprecedented speeds and as a result we upgraded nearly all of our infrastructure to keep up with our growth. We upgraded our generators, our battery systems, our solar array, our routers and switches, much of our electrical systems, our monitoring and alerting systems, our upstream internet pipes and our redundancy.

GeoSync VPS Hosting!

We’re extremely pleased to announce our new GeoSync Cluster hosting. A GeoSync Cluster is a fully automated, three-VPS cluster of servers spread across three data centers, in three different time zones.  If one data center goes offline your web site’s traffic will be automatically redirected to the remaining data centers, ensuring no downtime.  It is the ultimate hosting platform for those seeking redundancy, reliability, and ease-of-use.

Is this GeoSync Cluster hard to use?

No!  If you are a web site user (i.e. WordPress, Joomla, custom code, etc) or developer and your web site is hosted on our GeoSync Cluster service you might actually not notice the difference between it and regular hosting.  The service is fully automated (and amazing!) and comes with managed support if issues or questions arise. 

How does it work?

50kW of Solar Production

Our new 50kW solar parking structure has been live for a few weeks now, and WOW, we’re loving this. For a few hours each day its producing more power than our entire building is using: That includes our data center, our offices, and all lightening and cooling for Brownrice as well as THREE other businesses – one being our sister company TaosNet. Here’s a quick view our our electrical production (white arching curve) verse our usage (green squiggly line) yesterday. We anticipate that this array will produce about 66% of all of Brownrice’s electrical consumption over a year and or goal is to continue to add solar until all of our electrical usage is produced by the sun. Stay tuned, we’ll get there.
