I have install guacamole on nethservers and everything works fine.
I’m very happy with the result and now I can connect with SSH/RDP/VNC.
I have a strong password to login but I like to have a little more security so I have left username and password blank so it going to ask for that everytime I trying to login to one of my servers.
But the VNC have problem if I don’t have any password in the config file.
It doesn’t feel so secure so I wonder if you really have to have the password in the config file for VNC to work?
