After reinstalling Debian—whether version 10 (Buster) or 11 (Bullseye)—one of the most common headaches is losing your network configuration. If your setup uses bonded interfaces (LACP / 802.3ad) for redundancy, the reload wipes out all those settings. The system comes up, but there’s no proper connectivity until bonding is restored. This guide walks through the exact steps we follow at SupportPRO to bring the network back up after a reload, get the bonds working again, and make sure SSH is accessible. This process is crucial for server performance, high availability, …
If you run a cPanel server, you know the drill. It’s a constant battle—malware, spam, brute-force attacks, SYN flood attempts, DDoS threats, endless updates, and clients who expect things to “just work.” The last thing you need is waking up to a hacked website, seeing your IP dumped on a blacklist, or compromising your server security and network protection. That’s where cPGuard security suite comes in. It’s built specifically for web hosting security, shared hosting protection, and Linux server hardening, and honestly, it’s a lifesaver. So, what does cPGuard actually …
SYN floods have been around forever, and they’re still a major threat in Linux server security, especially for hosting providers and cPanel users. The trick is simple: attackers blast your server with a ton of TCP SYN packets, but never finish the TCP handshake. Your server ends up stuck, waiting on connections that never really start, eating up memory and connection slots until everything slows to a crawl—or just crashes. For web hosts, server administrators, and anyone running cPanel or other control panels, this means slow sites, broken services, and, …
If you’ve ever run a web hosting server, you know there’s one thing that can ruin your day faster than anything else — losing data. A failed update, a hacked account, or even a minor misconfiguration can wipe out hours of work. That’s why backups aren’t just an option; they’re your safety net. When it comes to the best software for cPanel backup solutions, two names keep popping up: JetBackup and Acronis Cyber Protect. Both are strong contenders, but they’re built for slightly different worlds. I’ve worked with both over …

RunCloud Security Explained: How Its Built-In Firewall Keeps Hackers Out 24/7
If you manage a website, even a small one, security is something you can’t brush aside anymore. Hackers don’t care how big your site is. They just care if it’s vulnerable.

If you’ve worked with servers for any amount of time, you’ve probably bumped into cPanel — it’s practically everywhere. For shared hosting, it’s fine.

You can manage several servers, handle deployments, monitor performance, and automate everything without logging into each box manually. If you’re still on the …
If you’ve ever had a website slow down the moment traffic picks up, you’ll know how helpless that feels. You open the dashboard, refresh the monitor, maybe even restart the service — and still, it lags. In most of those moments, the problem isn’t that your server is weak. It’s usually that PHP and your FPM pool just aren’t tuned quite right. I’ve spent a lot of long nights inside RunCloud dashboards, and over time I’ve built a habit of adjusting a few key settings whenever I launch or optimize …

A while back, I decided to try running my own email server instead of depending on Gmail or Outlook. It wasn’t just about curiosity but also about control. I wanted my data to stay on servers I manage, not in someone else’s giant datacenter. In this post, I’ll walk through how I got Postfix …
