Aria2 is a lightweight download software with Multi-Connection support. Besides HTTP(s) and FTP, it also supports BitTorrent and Metalink.

Since IKEv2 VPN supports MOBIKE and is natively supported by iOS 9, OS X 10.11 and newer, it’s a good choice for iOS and macOS. In my setup, I use Debian Stretch, unbound for DNS cache and dnscrypt-proxy for dnscrypt protocol.

I have a remote server with Intel E5 1620v2 CPU which supports VT-x, VT-d and EPT. The server runs with Debian Stretch and I need to set up a headless Window 10 virtual machine on it. After comparing different virtualizer products, I chose VirtualBox, which is free, and use Windows Remote Desktop as client.

I have two servers now, one in Canada and one in France. Due to the disk storage, I put this site on the France server and build a reverse proxy on the Canada server for a better time delay. Because I don’t want users to access the France server, I enable proxy_ssl_verify and and ssl_client_verify in NGINX. This article records a brief process of the set up. All servers are with Debian Jessie and NGINX 1.11.5.

Recently I setup nginx server with default modules and find that streaming the MP4 container format with the H.264 video codec and the AAC audio codec is supported by Chrome. But streaming the MKV container format with the same video and audio codec is not supported. Chrome starts to download the file after I click the link. Actually, there is no MKV type in nginx mime.types file. So I add video/webm mkv; to the file and it works.
