I want to use IRC/SSH at school but both seems to be blocked. I assume they blocked all ports outside of 80 and 8080. Is there anyway to get around this? Maybe a proxy? How would I set this up?
+1 on this. Easiest way to get around school filters - used to have this setup when I was in high school (well, OpenVPN, but same thing just different VPN tech).
A long time ago I used something like sockd to run a local proxy and then send that data to my personal remote proxy server over port 80, something like https://win2socks.com/ I think
Maybe there’s something better than socks these days.
Back then it worked pretty well, but I don’t think they were doing DPI. They (admin guys) did seem to notice large file transfers and seemed to be killing them manually.
I would assume most places these days will collect net flow data at least, so while https will protect the contents, they will be able to see the potentially unusual amount of data moving back and forth to your proxies IP.
I would suggest at least using a VPS to hide your schools IP address from the irc servers. And you may be in serious trouble if you get caught. If you’re in the UK you’re going to be risking jail time, and speaking from personal experience, they take this shit seriously.
There's a few WebSocket solutions out there. Basically looks like a normal HTTPS connection to something that uses a WebSocket, so unless they're decoding TLS and the HTTP session and somehow recognizes that this is a VPN and block it, it'll likely go through.
Just use a VPN. Proton VPN is a privacy-respecting and trustworthy provider with a pretty neat free plan, I used it for IRC many times, works very well. They have clients for pretty much every platform including Linux of course.
You can try Riseup VPN, the VPN client has a unique feature where it uses Tor to bypass the block on the VPN server and then connects to the VPN. You can also just try using Tor through Orbot and with a bridge like Snowflake or request a custom bridge from the Tor Project.
