There are 2 HTTP proxies running, tinyproxy (8080) and zipproxy (8081). zipproxy compresses any images that go through it. Connections only allowed from localhost, to connect you will probably want some SSH config such as:
Host marmot.wormnet.eu #DynamicForward localhost:1080 LocalForward 127.0.0.1:8080 127.0.0.1:8080 LocalForward 127.0.0.1:8081 127.0.0.1:8081
