| * Help class to process configurations of access points saved in an XML file. |
| * The configurations of an access point is included in tag |
| * <accesspoint></accesspoint>. The supported configuration includes: ssid, |
| * security, eap, phase2, identity, password, anonymousidentity, cacert, usercert, |
| * in which each is included in the corresponding tags. Static IP setting is also supported. |
| * Tags that can be used include: ip, gateway, networkprefixlength, dns1, dns2. All access points |
| * have to be enclosed in tags of <resources></resources>. |
| * |
| * The following is a sample configuration file for an access point using EAP-PEAP with MSCHAP2. |
| * <resources> |
| * <accesspoint> |
| * <ssid>testnet</ssid> |
| * <security>EAP</security> |
| * <eap>PEAP</eap> |
| * <phase2>MSCHAP2</phase2> |
| * <identity>donut</identity</identity> |
| * <password>abcdefgh</password> |
| * </accesspoint> |
| * </resources> |
| * |
| * Note:ssid and security have to be the first two tags |
| * for static ip setting, tag "ip" should be listed before other fields: dns, gateway, |
| * networkprefixlength. |
