The proxy file \e[33m~/socksproxy\e[0m is created.
Now to make it into use for the git:// protocol:

1) Edit or add to \e[33m~/.ssh/config\e[0m file with following entry.
   You may need to grant write permission to the file first.
\e[36m
Host *
    User git
    ProxyCommand ~/socksproxy '%h %p'
\e[0m
2) Give \e[33m~/.ssh/config\e[0m a strict permission for SSH
\e[36m
chmod 400 ~/.ssh/config
\e[0m
