I recently install Linux Mint Debian on my computer. It is working fine and I also have internet. But just firefox is able to get through the proxy.
After some research I found out that the ISA server in my network is automatically refusing all authentifications that are not encrypted. So setting a system wide proxy with using
export HTTP_PROXY="http://user:passwd@proxy:port/" Will not work.
So how do I get my system to send encrypted requests to the ISA server?
