I am a bit of a newbee with SSH+security, so I'm not sure if the assumptions in the following question are entirely correct...
I am in a hotel which uses
zscaler.com to monitor its guests' internet connections. My computer uses Windows 7, but I am running a VMWare guest with Fedora 23.
In the VMWare/Fedora guest I have set up Firefox to use a socks proxy:
ssh -ND 9876 firstname.lastname@example.org
Within Firefox, I have set
network.proxy.socks_remote_dns --> true network.proxy.socks_port --> 9876 network.proxy.socks --> localhost network.proxy.type --> 1
I had thought that using a socks proxy like this would prevent MITM monitoring of Firefox's web surfing, but it doesn't: for some web pages (e.g.
totalvpn.com), I get the hotel's warning page saying that the site I'm linking to is on their "forbidden" list.
When I started the socks proxy, as above, I got no warning that the link was not secure. Is there a way to force SSH to use a secure link or fail if it can't?
