Hello
Having the same question here, I figured it quite quick.
( The question is only 1 month old and well refered in Google, that's why I am posting this here )
The HYDRA_PROXY ( and sisters ) variables are environnement variables
you must add them in your console like this :
Code:
you@yourbox:~$ HYDRA_PROXY=http://127.0.0.1:8080
or ...
Code:
you@yourbox:~$ HYDRA_PROXY=socks4://127.0.0.1:8118
etc.
then type
Code:
you@yourbox:~$ export HYDRA_PROXY
check that your variable is now set in your environment :
Code:
you@yourbox:~$ printenv | grep HYDRA
When you'll launch you hydra command now, you will notice this line :
Code:
Hydra (http://www.thc.org/thc-hydra) starting at 2013-XX
[INFO] Using Connect Proxy: socks4://127.0.0.1:8118
