…orrrrr how to spoof your IP address:
# turn it on:
networksetup -setsocksfirewallproxy Ethernet <domain/ip of proxy> <proxy port>
# turn it off:
networksetup -setsocksfirewallproxystate Ethernet off
This, combined w/ opening an ssh tunnel on the destination proxy:
ssh -N -D 0.0.0.0:<proxy port> localhost
will make it look like all your online behaviors are emitting from the proxy. You probably want to setup a firewall on the proxy (e.g. iptables) so that you’re the only person that can use it as a relay, otherwise anyone can (and likely will, as the roving hand of malicious Romanian hackers looms on the not-so-distant horizon). Open chrome, and voila, go to town!
