 ScriptRunner scriptRunner)

Method Details

init

public void init()

getFirstIPv4Address

public Ip4Address getFirstIPv4Address()

Returns the primary IPv4 IP address

notifyIPAddressChanged

public void notifyIPAddressChanged(Ip4Address newIP)

This method actually updates the current IPv4 address from the network interface; Call this method, if e.g. the device got a new IPv4 address via DHCP in automatic mode.

notifyIp6AddressChanged

public void notifyIp6AddressChanged()

Once a NetworkInterface object has been created its IP addresses do not change. Therefore, an external process must detect IPv6 address updates and call this method to reload the NetworkInterface.

getIp6LinkLocalAddress

public Ip6Address getIp6LinkLocalAddress()

getAddresses

public List<IpAddress> getAddresses()

hasGlobalIp6Address

public boolean hasGlobalIp6Address()

getNetworkPrefixLength

public int getNetworkPrefixLength(IpAddress ipAddress)

Returns the network prefix length (in bits) of the given IP address

Parameters:

ipAddress - IP address

Returns:

-1 if there was no networkInterface

getHardwareAddress

public byte[] getHardwareAddress()

getHardwareAddressHex

public String getHardwareAddressHex()

getInterfaceName

public String getInterfaceName()

findGatewayAndWriteToRedis

public void findGatewayAndWriteToRedis()

Look for a gateway, and if found write it to Redis (script)

isUp

public boolean isUp()

getVpnIpv4Address

public Ip4Address getVpnIpv4Address()

getMtu

public int getMtu()

addIpAddressChangeListener

public void addIpAddressChangeListener(NetworkInterfaceWrapper.IpAddressChangeListener listener)
