VPS and Linux server guides
VPS guides covering Canadian VPS choices, Linux administration, SSH, firewalls, managed vs unmanaged hosting, security, dedicated servers, migrations, troubleshooting, and capacity decisions.
VPS & Linux
Understand the system, not just the setting.
A VPS gives you more control than shared hosting, which also means more operational responsibility. These guides explain what that responsibility includes and how to make the move when the workload actually benefits from a server of its own.

Cheap VPS Canada: how to compare a low-cost VPS
Compare a cheap VPS in Canada by CPU model, vCPU allocation, RAM, storage, network, IPv4, backups, virtualization, management, billing, and upgrade path.
VPSLinux VPS hosting: what are you responsible for?
Linux VPS hosting gives operating-system control. Learn the responsibilities around SSH, updates, firewall, web services, databases, TLS, backups, monitoring, logs, and incident response.
VPSManaged VPS Canada: what should management include?
Managed VPS services differ widely. Define whether management covers OS updates, web stack, monitoring, backups, security, incidents, migrations, applications, and response boundaries.
LinuxSSH connection refused: separate service, port and firewall failures
SSH connection refused usually means the host actively rejected the TCP connection. Check destination, port, sshd listening state, bind address, firewall, and recent changes.
LinuxSSH key setup: how public-key login works
SSH key setup uses a private key on the client and an authorized public key on the server. Learn generation, installation, permissions, passphrases, rotation, and recovery.
VPS & LinuxVPS CPU steal: how to check it and investigate a slow server
Check VPS CPU steal with vmstat, distinguish host CPU waits from your own workload, and collect useful evidence before changing plans.
VPS & LinuxVPS memory pressure: how to spot RAM exhaustion before an OOM kill
Read Linux memory, swap, reclaim and OOM signals together so you can tell normal cache use from a VPS that is genuinely running out of RAM.
VPS & LinuxVPS disk latency: how to find slow storage without guessing
Use latency, queue depth, I/O wait and workload evidence to determine whether a slow VPS is limited by storage, the application, or another resource.
VPS & LinuxVPS network latency: where delay comes from and how to trace it
Trace VPS network latency across DNS, routing, transport, proxies and the application so a high ping or slow page is not blamed on the wrong layer.
VPS & LinuxVPS packet loss: how to test it and locate the failing path
Test packet loss from more than one vantage point, compare hops and application symptoms, and avoid treating every ICMP anomaly as an outage.
VPS & LinuxLinux swap sizing: how much swap a VPS actually needs
Choose Linux swap based on workload, RAM pressure, hibernation needs and failure behaviour, then monitor whether swap is helping or hiding a memory problem.
VPS & LinuxLinux OOM troubleshooting: find what exhausted memory
Read OOM-killer logs, process memory, cgroup limits and workload timing to identify why Linux killed a process and what should change next.
VPS & LinuxLinux inode exhaustion: why free disk space can still mean no space left
Diagnose inode exhaustion by filesystem, find directories creating huge file counts, and clean up safely without confusing inode use with byte capacity.
VPS & LinuxLinux disk cleanup: free space without deleting the wrong data
Find what is consuming disk space, check logs, packages, caches and application data, then reclaim capacity with a rollback-aware cleanup plan.
SecurityLinux SSH hardening: reduce remote-login risk without locking yourself out
Harden SSH with keys, account controls, network policy and tested fallback access while keeping a recovery path before disabling working login methods.
SecurityLinux firewall basics: build rules around the services you actually run
Map listening services first, then apply a Linux firewall policy that permits required traffic, limits exposure and keeps administrative access recoverable.
VPS & LinuxLinux automatic updates: patch safely without surprise reboots
Plan unattended security updates, reboot handling, maintenance windows and verification so patch automation reduces risk without creating avoidable outages.
TroubleshootingLinux journal troubleshooting: use systemd logs to trace a failure
Use journalctl by unit, boot and time range, correlate service errors with system events, and preserve the evidence needed to diagnose recurring failures.
TroubleshootingLinux DNS troubleshooting: test resolver, network and authoritative answers
Separate local resolver failures from upstream DNS, routing and authoritative-zone problems using direct queries and the system resolver configuration.
TroubleshootingLinux NTP troubleshooting: fix clock drift and failed time sync
Check time sources, synchronization state, reachability and clock offset so TLS, logs, authentication and scheduled jobs are not broken by bad system time.
VPS & LinuxLinux process limits: understand ulimit, systemd and cgroup ceilings
Trace process, file-descriptor and task limits across the shell, systemd and cgroups before raising a ceiling that may be protecting the server.
VPS & LinuxLinux file permissions: ownership, modes, groups and ACLs explained
Understand Unix ownership and rwx modes, then use groups and ACLs where needed so services can access files without opening them to every user.
VPS & LinuxLinux service recovery: restart the right component and prove it is healthy
Use systemd state, logs, dependencies, sockets and application checks to recover a failed Linux service without turning a symptom into a larger outage.
VPS & LinuxVPS resize planning: know whether you need more CPU, RAM or storage
Measure the resource that is actually constrained, account for filesystem and application limits, and verify the workload after a VPS resize.
MigrationVPS migration checklist: move a server without losing the rollback path
Plan a VPS move across data sync, IP and DNS changes, certificates, services, validation and rollback so cutover does not depend on memory or luck.
BackupsVPS backup strategy: protect the data you cannot rebuild
Design VPS backups around application state, databases, configuration, retention, offsite copies and tested restores instead of relying on one server image.
BackupsVPS snapshot limitations: what snapshots protect and what they do not
Understand crash consistency, storage coupling, retention and application state before treating a VPS snapshot as a complete backup or recovery plan.
VPS & LinuxVPS benchmark methodology: test CPU, memory, disk and network fairly
Build repeatable VPS benchmarks with controlled workload, warm-up, multiple runs and clear environment notes so one synthetic score is not mistaken for reality.
VPS & LinuxVPS IPv6 setup: address, route, firewall and DNS checks
Configure IPv6 on a VPS by validating the assigned prefix, gateway or route, firewall rules, DNS records and real inbound and outbound connectivity.
VPS & LinuxVPS reverse DNS: how PTR records, forward DNS and mail identity fit together
Set and verify reverse DNS for a VPS, understand provider-controlled PTR records, and keep forward DNS and service identity consistent where it matters.
VPS & LinuxVPS vs dedicated server: when virtualization is no longer the right boundary
Compare isolation, hardware control, resource scale, failure domains, cost and administration before moving a workload from VPS capacity to a dedicated server.
