  • Countless emails wrongly blocked as spam after Cisco's SpamCop failed to renew domain name at the weekend

    Cisco's anti-spam service SpamCop failed to renew spamcop.net over weekend, causing it to lapse, which resulted in countless messages being falsely labeled and rejected as spam around the world.

    From what we can tell, this is what happened. When the domain name expired, *.spamcop.net resolved to a domain parking service's IP address. The way that SpamCop's DNS-based blocking list works is that if you, for example, want to check that an email sent from a system with the IP address 1.2.3.4 is legit, you run a DNS query on 4.3.2.1.bl.spamcop.net. If SpamCop returns a valid DNS entry for that lookup, then it's an IP address known to have sent out spam in the past and should be treated with suspicion.

  • Linode cloud firewall: Do you need it to protect the Linux server? - nixCraft

    inode is an original cloud platform and founded before AWS. Back then, we used to call them VPS (Virtual Private Server). Recently they added a new firewall feature to control network access to my Linode server from the Cloud. Let us test drive Linode cloud firewall.

  • New Year, More Bits

    I hope that everyone had a good start into the new year. The last one probably has been tough for most of us in many different ways. It has been for the IPFire Project, too.

    But we have tried to make the best we can out of it, and for this year, we have come up with an important decision that I would like to announce today: The development team has decided that we have to "cut costs" and we have decided to end support for the 32 bit x86 architecture by December 31st 2021.

    [...]

    IPFire has its roots way in the past and therefore we used to carry some technical features that are not relevant any more.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
