Note: Because of variations in install, multiple toolsets, (never knowing whether a previous install might have affected the next one); some/all(?) of the following information might be wrong; and there are probably better methods for doing the following. Keep this in mind and feel free to think a bit before blindly following the instructions. The following installation guides leave the systems with no open scannable ports for maximum security. It is assumed that users will enable the servers they require at a later date. (If you do install Xwindows at a later date, use of port 6000 by X can be disabled by adding the flag '-nolisten tcp' to the X server command line.)
