Class AuthenticateIP  

java.lang.Object
  edu.mit.wi.omnigene.service.mitog.webservice.server.AuthenticateIP

---

public class AuthenticateIP

extends java.lang.Object

Authenticates an IP address to a specified system or datastore. AuthenticateIP checks the incoming IP address to see if it's allowed to access the specified system or datastore. The access control list is a properties file that has a format of ip-address=system-name1,system-name2. The value is a comma delimited value of system names that the IP address is allowed to access. If a value of "all" is found then the IP address can access all systems and datastores. A value of "none" rejects the incoming request to any systems.
