figure 1.14: setting server security options
telnet and ftp security
Though they’re shown as options in the Fedora security configuration screens, both telnet and
FTP are widely recognized as insecure protocols. SSH is a much more secure option than telnet
for accessing remote machines, as SFTP is a more secure option than FTP for transferring files.
If an FTP capability is required, it’s recommended that it be set up on a different server that’s
isolated as much as possible from the rest of the network.
setting the time Zone
Fedora offers two options for setting the time zone for your server. You can roll the mouse over
the metropolitan area that’s closest to you, or you can select from an exhaustive list of cities. In
either case, the chosen city will be highlighted on the map, as shown in Figure 1.15.
