1. The connection info is stored at /etc/ppp/peers/
• The filename in this directory is the name of the connection 
2. The pptp options file, which should be listed in the connection file is typically stored at /etc/ppp/options.pptp
3. The secrets file, that contains your username and password, is stored at /etc/ppp/chap-secrets
4. To start the connection, type 

pppd call [connection name]
