How to instruct Squid to log user’s activity

There is two different setup/install instructions on OpenVPN's site, standard howto and static key howto. Static key is only usable for a 2 machine setup.

You will want to follow the standard howto: http://openvpn.net/index.php/open-source/documentation/howto.html

Basically you will need 2 configuration files, 1 for the server, 1 for the clients. You will need to create certificates and keypairs for the server, and for all the clients, each client will need it's own certificate and a copy of the servers certificate. Also watch out for the pitfall of having the same "Subnet" for client LAN's and your servers LAN. The client will not be able to easily access the servers LAN if it is the same subnet like 192.168.1.x.

Feel free to leave comments on spots where you get stuck, been through this setup many times.

I can confirm that the current lens doesn't support the cache_access_log parameter, and the best thing to do about this indeed is to open a ticket on the Augeas trac.

Some configuration files are trivial to map, and you can just specify a pattern (such as "key = value"). Others are more tricky, where some entries have a specific syntax, and others have a different one. For example, in the case of the squid lens, http_access or acl entries have a different syntax than the rest of the file. For this reason, it is necessary to list all know keys in the file to map them to the proper parser.

For such lenses, the best thing to do when a key is missing in the lens is to report it (or even better, to send a patch to the list, it's quite trivial in this case).

Looking forward to your ticket/patch!
