Methods Summary
public static native int	addHostRoute(java.lang.String interfaceName, int hostaddr) Add a route to the specified host via the named interface.
public static boolean	configureInterface(java.lang.String interfaceName, DhcpInfo ipInfo) When static IP configuration has been specified, configure the network interface according to the values supplied. param interfaceName the name of the interface to configure param ipInfo the IP address, default gateway, and DNS server addresses with which to configure the interface. return {@code true} for success, {@code false} for failure return configureNative(interfaceName, ipInfo.ipAddress, ipInfo.netmask, ipInfo.gateway, ipInfo.dns1, ipInfo.dns2);
private static native boolean	configureNative(java.lang.String interfaceName, int ipAddress, int netmask, int gateway, int dns1, int dns2)
public static native int	disableInterface(java.lang.String interfaceName) Bring the named network interface down.
public static native int	getDefaultRoute(java.lang.String interfaceName) Return the gateway address for the default route for the named interface.
public static native java.lang.String	getDhcpError() Return the last DHCP-related error message that was recorded. NOTE: This string is not localized, but currently it is only used in logging. return the most recent error message, if any
public static int	lookupHost(java.lang.String hostname) Look up a host name and return the result as an int. Works if the argument is an IP address in dot notation. Obviously, this can only be used for IPv4 addresses. param hostname the name of the host (or the IP address) return the IP address as an {@code int} in network byte order InetAddress inetAddress; try { inetAddress = InetAddress.getByName(hostname); } catch (UnknownHostException e) { return -1; } byte[] addrBytes; int addr; addrBytes = inetAddress.getAddress(); addr = ((addrBytes[3] & 0xff) << 24) | ((addrBytes[2] & 0xff) << 16) | ((addrBytes[1] & 0xff) << 8) | (addrBytes[0] & 0xff); return addr;
public static native boolean	releaseDhcpLease(java.lang.String interfaceName) Release the current DHCP lease. param interfaceName the name of the interface for which the lease should be released return {@code true} for success, {@code false} for failure
public static native int	removeDefaultRoute(java.lang.String interfaceName) Remove the default route for the named interface.
public static native int	removeHostRoutes(java.lang.String interfaceName) Remove host routes that uses the named interface.
public static native int	resetConnections(java.lang.String interfaceName) Reset any sockets that are connected via the named interface.
public static native boolean	runDhcp(java.lang.String interfaceName, DhcpInfo ipInfo) Start the DHCP client daemon, in order to have it request addresses for the named interface, and then configure the interface with those addresses. This call blocks until it obtains a result (either success or failure) from the daemon. param interfaceName the name of the interface to configure param ipInfo if the request succeeds, this object is filled in with the IP address information. return {@code true} for success, {@code false} for failure
public static native int	setDefaultRoute(java.lang.String interfaceName, int gwayAddr) Add a default route for the named interface.
public static native boolean	stopDhcp(java.lang.String interfaceName) Shut down the DHCP client daemon. param interfaceName the name of the interface for which the daemon should be stopped return {@code true} for success, {@code false} for failure
