In order to access the Installation Console, you need to manually set the IP address of your computer to 169.254.0.2. You will need to open System Preferences, once there open Network It would be a good idea to to edit the Locations so that you can easily change from DHCP to manual IP simply. On Windows 10, setting a static IP address to your computer is an essential configuration that may be required in a number of scenarios: For example, if you’re planning to share files or a printer on a local network, or when trying to configure port forwarding.
Find Ip On Mac
To connect to a virtual private network (VPN), you need to enter configuration settings in Network preferences. These settings include the VPN server address, account name, and any authentication settings, such as a password or a certificate you received from the network administrator.
How To Set Static Ip In Linux Machine
If you received a VPN settings file from your network administrator, you can import it to set up your connection. If you didn’t, you can enter the settings manually.
Import a VPN settings file
On your Mac, do one of the following:
- Double-click the file to open Network preferences and automatically import the settings.
- Choose Apple menu > System Preferences, click Network, click the Action pop-up menu , then choose Import Configurations. Select the file, then click Import.
Enter VPN settings manually
- On your Mac, choose Apple menu > System Preferences, then click Network.
- Click the Add button in the list at the left, click the Interface pop-up menu, then choose VPN.
- Click the VPN Type pop-up menu, then choose what kind of VPN connection you want to set up, depending on the network you are connecting to. Give the VPN service a name, then click Create.
- L2TP is an extension of the Point-to-Point Tunneling Protocol used by Internet service providers to enable a VPN over the Internet.
- IPSec (Internet Protocol Security) is a set of security protocols.
- IKEv2 is a protocol that sets up a security association in IPSec.
- Enter the server address and the account name for the VPN connection.
- Click Authentication Settings, then enter the information you received from the network administrator.
- If specified by your network administrator, click Advanced to enter additional information such as session options, TCP/IP settings, DNS servers, and proxies.The additional information you can enter depends on the type of VPN connection you’re setting up.
- Click Apply, then click OK.
Select “Show VPN status in menu bar” to use the VPN status icon to connect to the network and switch between VPN services.
To remove the VPN configuration, select the VPN network connection service in the list and click the Remove button .

< Changing Your MAC Address
Under GNU/Linux, the MAC address of a network interface card (NIC) can be changed by following the procedures below.
NOTE: MAC addresses used within this article are provided for example only. Substitute according to your requirements.
NOTE: Commands below MUST be executed with root privileges (e.g. prepended with 'sudo '), in order for things to work!
NOTE: Commands below MUST be executed with root privileges (e.g. prepended with 'sudo '), in order for things to work!
/etc/init.d/networking stop
ifconfig eth0 hw ether 02:01:02:03:04:08
/etc/init.d/networking start
Execute '
ifconfig eth0
' to confirm.The above should work on Debian, Ubuntu, and similar distributions. Alternatively, under RHEL/Fedora and possibly other GNU/Linux distributions (incl. CentOS and Scientific Linux), to disable and restart networking, one must stop and start
/etc/init.d/network
, instead of /etc/init.d/networking
.If you have iproute2 utilities installed, you may prefer to use the '
ip
' command, as follows:/etc/init.d/network stop
ip link set eth0 address 02:01:02:03:04:08
/etc/init.d/network start
To confirm your setting, you may prefer to execute '
ip link ls eth0
' or 'ip addr ls eth0
' instead of 'ifconfig eth0
'.NOTE: You may not be able do this if using a DSL modem (depending on modem vendor or ISP).
Making Changes Permanent - Surviving a Reboot[edit]
In openSUSE and other SUSE-based systems (SUSE enterprise desktopserver, etc.) you can make changes 'permanent' across reboots by adding an appropriate entry to the /etc/sysconfig/network/ifcfg-ethN file (ifcfg-eth0 for the first Ethernet interface config file, ifcfg-eth1 - for the second, etc.):
LLADDR=12:34:56:78:90:ab
In Red Hat Enterprise Linux (RHEL) and other similar systems (Fedora, CentOS, etc.) an easy way to make changes 'permanent' across reboots is to add an appropriate entry to the /etc/sysconfig/network-scripts/ifcfg-ethN file (ifcfg-eth0 for the first Ethernet interface config file, ifcfg-eth1 - for the second, etc.):
MACADDR=12:34:56:78:90:ab
Note: in the file is a value HWADDR - This is not the same thing. Use MACADDR for permanent changes.
from http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-networkscripts-interfaces.html
The HWADDR 'directive is useful for machines with multiple NICs to ensure that the interfaces are assigned the correct device names regardless of the configured load order for each NIC's module. This directive should not be used in conjunction with MACADDR.'...The MACADDR 'directive is used to assign a MAC address to an interface, overriding the one assigned to the physical NIC. This directive should not be used in conjunction with HWADDR.'
Upper and lower case letters are accepted when specifying the MAC address, because the network function converts all letters to upper case.
You can test changes without restarting the system by executing:
service network restart
(WARNING: doing this will break all existing network connections!)
On Debian, Ubuntu, and similar systems, place the following in the appropriate section of /etc/network/interfaces (within an iface stanza, e.g., right after the gateway line) so that the MAC address is set when the network device is started:
hwaddress ether 02:01:02:03:04:08
On Gentoo you may achieve the same result by adding an entry to the global configuration file /etc/conf.d/net for each Ethernet card. Example for the eth0 device:
mac_eth0='12:34:56:78:90:ab'
You can also use the tool 'GNU MACChanger' to change the MAC address under GNU/Linux.
To change MAC address during boot time with MACChanger, add the following line to your /etc/network/interfaces (example for the eth0 interface):
pre-up macchanger -m 12:34:56:78:90:AB eth0
