Here’s a minimal setup for proxytunnel:

Apache2:

[...]
        ProxyRequests On
        AllowConnect 22
        <Proxy *>
                Order deny,allow
                Deny from all
        </Proxy>
        <Proxy 127.0.0.1>
                Order deny,allow
                Allow from all
        </Proxy>
[...]

Local SSH configuration:

Host vps_proxy
  ProxyCommand proxytunnel -q -E -p VPS_IP:443 -d 127.0.0.1:22 -z
  DynamicForward 1080
  ServerAliveInterval 60
  Port 443

Set up local SOCKS5 proxy:

ssh -D 1337 -q -N -f -C vps_proxy

tsocks (to run any command through an SSH tunnel) configuration:

/etc/tsocks.conf

[...]
server = localhost
server_type = 5
server_port = 1337

Try connecting to any ssh host:

tsocks ssh ...
