You need a proper CLI client that works headless, a protocol that holds up under long uptime, a kill switch that actually blocks traffic when the tunnel drops, and ideally some way to build a private network between multiple servers without managing your own VPN infrastructure. The consumer-focused VPN comparison guides don't cover this.</p>https://www.linuxhosted.com/post/nordvpn-linux-vps-review/Mon, 11 May 2026 00:00:00 +0000https://www.linuxhosted.com/post/nordvpn-linux-vps-review/ <p><a href="https://nordvpn.com/">NordVPN</a> is one of the few mainstream VPN providers that has put real engineering effort into its Linux client. The CLI is full-featured, the NordLynx protocol (WireGuard-based) runs efficiently on server hardware, and the Meshnet private networking feature addresses a use case that most VPN providers don't touch. If you're running a VPS and want a VPN for secure outbound routing, private server-to-server networking, or protection on untrusted networks, NordVPN is worth evaluating seriously.</p>https://www.linuxhosted.com/post/how-to-install-nordvpn-ubuntu-vps/Sun, 10 May 2026 00:00:00 +0000https://www.linuxhosted.com/post/how-to-install-nordvpn-ubuntu-vps/ <p>Running a VPN on a VPS isn't just for privacy — it's useful for securing outbound traffic, routing through a different exit node for region-sensitive services, and building private networks between servers using NordVPN's Meshnet feature. This guide covers installing NordVPN on an Ubuntu 22.04 server, configuring it for headless operation, enabling the kill switch safely, and optionally setting up Meshnet for private server-to-server networking.</p> <div class="notices info"> <div class="label">What This Guide Covers</div> Ubuntu 22.04 LTS, headless CLI install via the official apt repository, NordLynx (WireGuard) as the default protocol, kill switch with SSH allowlist to avoid locking yourself out, and Meshnet configuration. Estimated time: 10–15 minutes. </div> <hr> <h2 id="prerequisites">Prerequisites</h2> <ul> <li>An Ubuntu 22.04 LTS VPS with sudo access (connected via SSH)</li> <li>A NordVPN account — <a href="https://www.dpbolvw.net/click-852178-12814518">get one here</a> if you don't have one yet</li> <li>Basic familiarity with the Linux command line</li> </ul> <p>This guide is written for Ubuntu 22.04. The same steps work on Ubuntu 20.04 and 24.04, and with minor adjustments (replacing <code>apt</code> with <code>yum</code> or <code>dnf</code>) on Debian, Fedora, RHEL, and CentOS.</p>
