The * protocol string is simply there to support an environment where you run * multiple openvpn daemons to listen on different ports or protocols, it is * a plain text field, suggested values are 'UDP', 'TCP', 'UDP/1234' etc. * * Returned entries are indexed based on client host:port since that is * guaranteed to be unique, common name wouldn't be unique since you can * connect multiple times with the same cert. * * The parser will return a multi dimentional array given the status log above * that looks like this: * * Array * ( * [updated] ⇒ Thu Mar 3 17:30:55 2005 * [users] ⇒ Array * ( * [0] ⇒ Array * ( * [CommonName] ⇒ common.name * [RealAddress] ⇒ 1.2.3.4:21370 * [BytesReceived] ⇒ 86.39 KB * [BytesSent] ⇒ 87.18 KB * [Since] ⇒ Thu Mar 3 13:39:10 2005 * [Proto] ⇒ UDP * [VirtualAddress] ⇒ 192.168.57.10 * [LastRef] ⇒ Thu Mar 3 13:39:11 2005 * ) * [1] ⇒ Array * ( * [CommonName] ⇒ another.common.name * [RealAddress] ⇒ 7.8.9.1:54836 * [BytesReceived] ⇒ 158.04 KB * [BytesSent] ⇒ 166.02 KB * [Since] ⇒ Thu Mar 3 13:39:10 2005 * [Proto] ⇒ UDP * [VirtualAddress] ⇒ 192.168.57.14 * [LastRef] ⇒ Thu Mar 3 17:27:14 2005 * ) * ) * ) * * I use a Smarty template to print out the data like this: * * <table> * {section name=u loop=$tcpusers} * <tr bgcolor=“{cycle values=”#eeeeee,#dddddd“}”> * <td>{$tcpusers[u].CommonName}</td> * <td>{$tcpusers[u].RealAddress}</td> * <td>{$tcpusers[u].VirtualAddress}</td> * <td>{$tcpusers[u].Since}</td> * <td>{$tcpusers[u].BytesSent}</td> * <td>{$tcpusers[u].BytesReceived}</td> * <td>{$tcpusers[u].LastRef}</td> * <td>{$tcpusers[u].Proto}</td> * </tr> * {/section} * </table> * * * R.I.Pienaar rip@devco.net * 03/03/2005 * http://www.devco.net/ * */
