修改centos7/osx的MAC地址
change MAC Address in CentOS 7:
nano /etc/sysconfig/network-scripts/ifcfg-ens160
systemctl restart network.service
或者: /etc/init.d/network restart
You are done. Now, verify by issuing ifconfig command.
If you have a windows machine in the same network. Issue arp -d to delete current ARP table. Then ping CentOS 7 IP Address from Windows PC. Next issue arp -a. You will find the changed MAC next to your CentOS 7 IP Address.
注意: ifcfg-ens160本身的HWADDR不要改动:
Note: in the file is a value HWADDR - This is not the same thing. Use MACADDR for permanent changes.
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."
osx上修改mac地址,先删除文件:
rm /Users/xxxx/Library/Preferences/com.teamviewer.TeamViewer.plist
rm /Users/xxxx/Library/Preferences/com.teamviewer.teamviewer.preferences.plist
sudo rm /Library/Preferences/com.teamviewer.teamviewer.preferences.plist
