These are all very interesting, I am currently facing an issue getting BitTorrent file transfer to pierce an "unfriendly" firewall that I can't change permissions on. I've tried a VPN out with no luck. I wish I knew if one of these would allow me to get out.
- kibwen 7y agoFirefox Send is a web page, so if you can access the web you can use it. Also, a firewall that you can access the web from will have ports 80 (http) and 443 (https) open, so configure your tools to use one of those (preferably 443). If both machines are standard internet-facing Unix-likes that you have accounts on, you'll already have scp preinstalled for easy file transfer.
- sudosysgen 7y agoMany modern firewalls do Deep Packet Inspection, so obfuscation might be needed too.
- kibwen 7y agoAs long as your traffic is encrypted (which ssh/scp is) and as long as your machine isn't compromised then a firewall can tell so little about your traffic that it would have to be pretty paranoid to attempt to block any of it. It'll work at a Starbucks, but perhaps not in China.
- sudosysgen 7y agoDeep packet inspection will almost invariably be able to recognize ssh/scp from the packet sizes, the patterns, the ports and so on. You really do need some kind of obfuscation. Starbucks won't catch it, but I know for a fact my former high school does, for example.
- big_chungus 7y agoShadowsocks can get past most. Many have yet to update to catch wireguard, too.
- heyflyguy 7y agothis would work for me if I either had alot of patience or a different dataset. I can either send 1 70GB file or 70 1GB files.
