Is your VPS suffering from 'stolen' CPU cycles? We dissect the architecture of OpenVZ containers, analyze the risks of shared kernels, and explain why strict resource isolation matters for mission-critical Norwegian infrastructure.
Client-side tracking lies. Discover how to configure AWStats on your Linux VPS to uncover bandwidth thieves, fix 404 errors, and audit traffic with forensic precision.
RAID provides redundancy, not backup. If you delete a file, RAID deletes it everywhere. Learn how to implement bulletproof, automated offsite backups using rsync and MySQL best practices tailored for Norwegian compliance.
Raw access logs tell the truth, but they are impossible to read. Learn how to deploy AWStats for granular traffic insights without killing your server's I/O performance. Optimized for CentOS 5 and Debian Lenny.
Is Apache eating all your RAM? Learn how to deploy Nginx 0.7 as a high-performance reverse proxy to handle massive concurrency without crashing your server.
Stop letting noisy neighbors kill your database performance. We explore why Kernel-based Virtual Machine (KVM) is superior to containerization for production workloads in 2009.
Is Apache's memory footprint killing your VDS performance? We benchmark the industry standard against the event-driven challenger, Lighttpd, to see which server handles the C10k problem best on dedicated Norwegian silicon.
In 2009, using plain FTP is professional negligence. We analyze the packet-level risks, configuration nuances on CentOS 5, and why SFTP is the only compliant choice for Norwegian data standards.
Stop waking up to 3 AM panic calls. We dive deep into configuring Nagios 3 and Munin on CentOS 5 to distinguish between a real downtime event and a harmless load spike, all while keeping Datatilsynet happy.
Tired of 'burst RAM' limits and oversold OpenVZ containers? We dive deep into the Kernel-based Virtual Machine (KVM) architecture, benchmarking I/O performance on Linux 2.6, and why strict resource isolation is the only way to survive a Slashdotting in 2009.
Is OpenVZ reliable enough for production, or is it just a cheap sandbox? We analyze /proc/user_beancounters, kernel resource locking, and why the Norwegian Data Inspectorate might care about your shared kernel.
Stop letting Apache eat your RAM. Learn how to implement the PHP-FPM patch with Nginx on CentOS 5 to handle thousands of concurrent connections without swapping, specifically tailored for high-traffic Norwegian environments.
Stop script kiddies cold. A battle-hardened guide to securing your CentOS and Debian servers using iptables, SSH keys, and common sense. Written for the paranoid admin.
Stop gambling with oversold OpenVZ containers. We dissect why KVM's isolated kernel architecture is the only viable choice for stability in 2009, specifically for high-load MySQL and Magento deployments.
Is your VPS actually giving you the RAM you paid for? We dissect OpenVZ architecture, memory barriers, and why /proc/user_beancounters is the most important file you aren't reading.
Stop fighting blacklists. A battle-hardened guide to configuring Postfix for high deliverability, security, and performance in the Norwegian hosting landscape.
As we approach 2010, 'Cloud' is the new buzzword, but disk latency remains the silent killer of web performance. We analyze RAID 10 SAS vs. emerging SSD tech, Xen virtualization, and why data sovereignty in Norway beats US-based hosting.
Raw access logs are useless without visualization. Learn how to deploy AWStats 6.9 for granular traffic intelligence while navigating Norwegian Datatilsynet privacy requirements and optimizing Perl execution time on high-performance virtual servers.
Stop relying on shared hosting for email. Learn to configure a hardened Postfix server on Linux, handle rDNS correctly, and keep your IP clean in the Norwegian hosting market.
Is your Apache server ready for the Digg front page? Learn how to deploy HAProxy 1.3 to split traffic, reduce load, and why dedicated kernel resources on Xen are non-negotiable for stability.
A battle-hardened guide to setting up Postfix on CentOS 5/Debian Lenny. Learn to secure port 25, master main.cf restrictions, and keep your IP off Spamhaus blacklists.
Stop relying on user complaints to know when your server is down. We dive deep into configuring Nagios 3 for alerting and Munin for trending, ensuring your infrastructure stays online while you sleep.
OpenVZ overselling is destroying your database performance. We explore why Kernel-based Virtual Machine (KVM) with virtio drivers is the only architecture serious sysadmins should trust in late 2009.
Tired of 'noisy neighbors' crashing your database? We dissect why Xen PV beats OpenVZ for mission-critical hosting and how to tune CentOS 5 domU instances for raw performance on Norwegian infrastructure.
RAID 10 won't save you from rm -rf. Learn the battle-tested scripts, remote sync strategies, and Norwegian compliance rules (Personopplysningsloven) to keep your data safe.
