When using the "vulfocus" target machine to install the vulnerable image, I found that the image management backend could not be accessed through the IP address (vulfocus could not be accessed through "127.0.0.1"). I thought it might be caused by changing the WI-FI.
Restarting the system took time, so I decided to restart the network card.
systemctl restart network
It's uncomfortable~~~~~~
After Baidu, it hurts even more~~~~~~
Restart command of ordinary system: systemctl restart network
Kali system restart command: systemctl restart networking / service networking restart
systemctl restart networking
