My machine A is running CentOS 7 core without GUI. I have installed the latest version of TigerVNC Server. How can I modify the configuration so that it can connect to my machine B's internal IP address, such as 192.168.0.200 on port 5500, in reverse at startup?
Probably. How depends on how you've set up things.
I would suggest starting a discussion in the tigervnc-users group. The issue tracker is better suited for specific bugs or features, rather than usage questions.
