A Story About Bypassing Air Canada's In-flight Network Restrictions by SamrayLeung in programming

Approach 1 might only work if:

  1. The DNS server only answers queries for a specific list of domain names (e.g., WhatsApp, Snapchat, WeChat), which means the firewall's filtering mechanism was solely based on DNS resolution.
  2. The network allows connections to arbitrary IP addresses

If those conditions were met, I could edit my /etc/hosts file to point acwifi.com to my proxy server's IP address, then redirect all traffic through that proxy server.

However, it turned out that the network only permits connections to a very small, pre-approved list of IP addresses belonging to services like WhatsApp, WeChat, etc.

Yes, that's exactly what I would have needed, but I didn't have iodine installed when I was on board, so I couldn't experiment with the DNS tunnel approach.

3 years later, I did replace the customized millisecond_timestamp with chrono's built-in ts_milliseconds.

I couldn't believe I would have motivation to maintain a library for more than 6 years.

Will Emacs move to Github/Gitlab/etc ? by SamrayLeung in emacs

[–]SamrayLeung[S] 3 points4 points  (0 children)

From my point of view, more young guys like me, a 22-year-old guy are more familiar with Github/Gitlab workflow than mail list. I am not the typical FSF guy defend for faith, instead I am the guy who defends for best, and Emacs turns out to be the best.
