Troubleshooting
The service does not start automatically when Ubuntu
There is a problem with the default configuration Privoxy 3.0.13 as provided by Ubuntu. Privoxy is configured to listen for connections from the localhost: 8118. The problem is that when the service starts Privoxy, the hostname localhost is not yet associated with any known IP address.To solve the problem, you must modify the configuration file so that Privoxy listens for connections from the address 127.0.0.1:8118. In this way, Privoxy does not need to make a connection between a host name (localhost) and IP address (127.0.0.1) as directly recognizes a local IP address valid. It can start automatically when Ubuntu.
To change the default configuration Privoxy:
1-This can be qu'effectué by an administrator account. Sign in to an account with administrative rights, or ask an administrator to correct the problem for you;
2-In a terminal, open the configuration file of Privoxy / etc / privoxy / config:
