GPU Passthrough with QEMU on Arch Linux

GPU passthrough allows native graphics performance in the virtual machine which opens up new possibilities. One major use case is virtualized gaming as well as hardware acceleration for certain applications like Adobe Creative Suite. Steam In-Home Streaming opens up some odd but functional configurations by leveraging the VM to stream to clients on a local network. A major advantage of running Steam in a VM is that it does not prevent the use of the host system while streaming. In practice this could mean that two different users could simultaneously make use of the same system.

Passwordless SSH logins on Linux

You Shall Not Password - Password-less SSH login

Passwordless SSH logins offer vast security improvements over standard password login. Additionally once setup passwordless logins offer a convenience of not having to enter a password when logging in from the same system.

screenFetch is a Bash Screenshot Information Tool that prints ASCII art along with basic system information when executed. Many distributions are supported with unique ASCII art included. It is useful to run it on login automatically to immediately see system information.

ownCloud on Shared Web Hosting

ownCloud is an open-source, self-hosted cloud service that can be installed on a local or remote server. For better performance and reliability it’s best to host it on a commercial hosting service. Both dedicated and shared web hosting packages will work assuming the service is reasonably feature rich. If reliability is not an issue it can be hosted on a local home server without issues as well.

OpenSSH Server on Arch Linux

OpenSSH allows powerful and convenient way to remotely access remote systems. However it creates a possible security weakness which is one reason it is not installed by default. With proper configuration it can be secured and allows the administration of headless servers servers or other devices.

Custom Dynamic DNS Service on Arch Linux

Setup Custom Dynamic DNS Service on Arch Linux

DDNS or Dynamic Domain Name System service makes reliable remote access without a static IP. The setup consists of the client script that runs on the Linux machine and the back-end service that is hosted on a remote server. The client periodically sends it’s own external IP to the remote server. The remote server will then be able to redirect to the dynamic IP of the local client. If you do not have a remote server with a static IP to host your custom service you can instead setup No-IP DDNS on Arch Linux. The advantage of a custom Dynamic DNS server is that it remains under your control and there are no limitations as with free services.

Configure Apache User Passwords on Arch Linux

Configure Apache User Passwords on Arch Linux

Apache server by default does not have any authentication when accessing web directories. This may be desirable for only locally accessible addresses but would present a security and privacy issue when available externally. If you plant to setup No-IP DDNS on Arch Linux, custom DDNS on Arch Linux or just setup port forwarding on it’s own, it is important to secure all applications that will be accessible externally. Before configuring authentication make sure to install Apache web server.

Setup No-IP Dynamic DNS Service on Arch Linux

noip-arch

No-IP is a free DDNS or Dynamic Domain Name System service. The setup consists of the No-IP client that runs on the Linux machine and the No-IP back-end service that is hosted by No-IP. The client is very easy to install and once configured will periodically connect to No-IP back-end service and save the IP of the client. No-IP back-end will then be able to redirect to the dynamic IP of the client machine. As an alternative a custom Dynamic DNS service can be configured on a remote server.
