Windows client
Windows on the desktop from an admin’s perspective: Remote Desktop, printing, Group Policy, and the registry tweaks that make the difference in day-to-day support.
NewPort Forwarding with netsh portproxy: Access Internal Services Through a Jump Host
Windows includes built-in TCP port forwarding with netsh interface portproxy. Combined with a VPN such as Tailscale, it lets you access an internal service, such as a NAS interface, from outside without exposing it publicly. Learn how to set up, secure, and remove forwarding, and where its limitations lie: no UDP, no additional encryption, and certificate and redirect pitfalls.
Prerequisites for Remote PowerShell to Work
PowerShell remoting rarely fails because of the command itself, but rather because of prerequisites: the WinRM service, listener, firewall, authentication, and the specifics of local accounts. What needs to be configured on the target and client sides, how to check it with Test-WSMan, and why Access denied usually has nothing to do with the password.
Passwordless Linux Server Access: Set Up SSH Key Login with PuTTY, Pageant, and More
Admins who access Linux servers daily have to enter a username and password every time when using password login. An SSH key pair reduces this to a double-click: generate a key with PuTTYgen, store the public key on the server, and load Pageant. The same key works in WinSCP, MobaXterm, and OpenSSH, and if desired, takes you straight to a service account shell.
