How do I connect to a server behind an socks5 proxy through SSH on mac/linux?

you'll need a connect module for ssh which is able to connect through SOCKS.

We use it in our Lab all the time, here's our documentation on how to get it: https://wiki.enterpriselab.ch/el/public:tools:ssh#using_socks_proxy

In Ubuntu (and I believe so in Debian too) it's available as package, just install with

apt-get install connect-proxy

it will get installed as /usr/bin/connect-proxy

-D creates a SOCKS proxy. If you want to connect via a SOCKS proxy instead then you'll have to use connect as a proxy command.
