There are multiple commands which allow a user or administrator to either view or change the system configuration, though most such changes must be made by the root user (uid0) or equivalent.
To view the networking configuration for instance, you may issue the command:
# ifconfig -a
To view the routing table, you could issue the command:
# netstat -r
To view the current network connections you could issue the command:
# netstat -a (though you'll likely want to pipe the output into the less command)
To view the current process table you could issue the command:
# ps -afe
All of the above commands have many, many switches not mentioned in this response and this response is necessarily incomplete. For more information on the above commands, consult your system's man pages...
$ man netstat
or
$ man ifconfig
etc...
or consider acquiring one or more of the books published by Tim O'Reilly. I have dozens of them. [JMH]

The system information utility
It depends on the operating system you are using. Most windows systems use the 'ipconfig' command to look at the network adaptor configuration, whereas Unix/Linux use the 'ifconfig' command.
/etc/login.defs and /etc/passwd
Typically the 'exit' command gets you out of the current shell environment you are in; if this is the login shell then you will be logged out of the system.
Ifconfig stands for interface configuration. It is a system administration utility in Unix-like operating systems to configure, control and query TCP/IP network interface parameters from a command line interface or in system configuration scripts.
