Blog

VPS dives into Virtual Private Servers. Imagine a physical server sliced into multiple virtual sections, each acting like its own dedicated server. VPS hosting offers increased control, security, and performance compared to shared hosting, but with more flexibility and affordability than a dedicated server. This tag equips you with the knowledge to decide if a VPS is the right fit for your website’s needs.

A Stale PostgreSQL Replication Slot Can Fill Your Disk

A Stale PostgreSQL Replication Slot Can Fill Your Disk

Do not delete files from pg_wal to solve a growing PostgreSQL disk. A persistent physical or logical replication slot tells PostgreSQL that a consumer may still need old write-ahead log records. If that consumer stops advancing, the primary can retain WAL from the slot's restart_lsn while ordinary ...

Fix Linux VPS Clock Drift Without Breaking Running Services

Clock drift rarely introduces itself as “clock drift.” It arrives as a certificate that is “not yet valid,” an expired login token that was just issued, a cron job recorded in the wrong minute, database rows that appear out of order, or logs whose timeline cannot explain ...

Cloud-Init Says Done, but Your VPS Is Not Ready

A new VPS can carry three different clocks. The provider may label it running when the virtual machine starts, cloud-init may report done after its configured stages finish, and the workload may still fail its first real request. Treating those clocks as one status turns a small ...

Why systemd Stops Restarting a Failed Service
Linux Guides

Why systemd Stops Restarting a Failed Service

start-limit-hit is not the reason your application failed. It means systemd observed too many start attempts inside the unit's configured interval and refused another activation. The real cause happened earlier: a bad path, missing credential, permission error, occupied port, failed dependency, process crash, timeout, or another condition ...

Anycast or GeoDNS? Match Failover to the Failure Mode

Anycast or GeoDNS? Match Failover to the Failure Mode

Anycast and GeoDNS are often presented as rival ways to send users toward a nearby server. That comparison hides the decision that matters. Anycast lets network routing choose one of several sites serving the same IP address. GeoDNS lets authoritative DNS choose which address to return for ...

Harbor on a VPS: Operate a Recoverable Private Registry

Harbor on a VPS: Operate a Recoverable Private Registry

A private registry becomes part of the deployment path the moment CI pushes an image that production must later pull. Installing Harbor is therefore the easy decision. The harder one is accepting ownership of its certificates, database, artifact storage, scanner data, robot credentials, cleanup jobs and restore ...

Windows Server Patching with a Tested RDP Return Path

A Windows Server update can install successfully and still turn a routine maintenance window into an access incident. The server may reboot, answer ping and even show as powered on while Remote Desktop, a critical Windows service or the hosted application remains unavailable. The safest patch process ...

Redis to Valkey: A Single-Writer Migration Plan

The dangerous moment in a Redis-to-Valkey migration is not installing the new binary. It is the interval when two servers could accept different writes, while a green PING makes the change look finished. A safe VPS migration proves the source is compatible, rehearses the target with real ...

LiteLLM AI gateway separating application virtual keys from protected provider credentials on a VPS.
Artificial Intelligence

Keep LiteLLM Provider Keys Out of Every Client App

LiteLLM Proxy can give several applications one OpenAI-compatible endpoint without distributing the underlying provider credentials. The safe pattern is to keep the gateway on a controlled VPS, bind its raw port to loopback, terminate HTTPS at a reverse proxy, reserve the master key for administration, and issue ...

Vaultwarden recovery workspace separating the database, attachments and signing keys from a clean restore environment.
Security And Vulnerability

Back Up Vaultwarden Without Losing Attachments

A recoverable Vaultwarden backup needs more than db.sqlite3. Capture a consistent database, file attachments, any Sends you intend to preserve, the RSA signing keys and the configuration that cannot be recreated safely from memory. Move an encrypted copy away from the VPS, then restore it into an ...
