Ubuntu - change dns server for proxychains

This is really a not for myself, so that I don't forget it. So if you are using proxychains to access some servers through a proxy, you might want to use that system's dns server. In that case, presuming that you are running ubuntu, please modify the file:

/usr/lib/proxychains3/proxyresolv

When you open the file, it will be obvious what needs to be changed.
