Install xrdp and vncserver on centos7, and then use the rdp or vnc protocol to connect remotely many times,after that the centos server login becomes difficult. It used to take 2s to log in successfully through the ssh protocol, but now it may take 60s. The rdp and vnc protocols can no longer be used, and often need to restart the virtual machine to resolve
When I say that I have logged in to the centos7 system through the rdp and vnc protocols many times, it means no more than 50 times, maybe only 20 times, and each time does not exceed half an hour. Of course, I connected via guacamole I want to ask if you have such a problem. Is it a problem with my operating system?
