I am running a VPS with FreeBSD 8.3-RELEASE-p3
I locked myself out of su by taking my user out of wheel group.
I have disabled the ability to login with 'root' from SSH in order to increase the security level of my server.
I know that someVPS providers provide remote console control service that allows you to see what's going on the screen while booting and everything, but mine doesn't allow that.
Will installing VNC for command-line use only, keep me unworried of making mistakes like taking myself out of 'wheel' and not being able to 'su'?
