- Introduction
-
- 11.. PPuurrppoossee
-
- The network operation mode is selected either at boot time using
- askrunlevel (called automaticly) or anytime, using the "netconf
- --runlevel" command.
-
- Basically, _L_i_n_u_x can operate in three different ways, network wise.
-
- ╖ Stand-alone (local) mode.
-
- This mode is selected when no network adaptor is installed. It
- might be selected to save some rams.
-
- This mode configure the loopback interface allowing you to do
- minimal "local" networking (which is a good way to practice without
- bugging system administrators).
-
- ╖ Client mode.
-
- In this mode, only the minimal daemons necessary to access the
- network are started. While minimal, the iinneettdd daemon is activated,
- allowing your computer to provide some services such as telnet.
-
- ╖ Server mode.
-
- All daemons configured will be started.

-
- Your are allowed to switch the network operation mode on the fly using
- the following commands:
-
- ╖ netconf --runlevel local
-
- ╖ netconf --runlevel client
-
- ╖ netconf --runlevel server
-
- In each case, it will make sure the proper daemons are running.
-
- The command
-
- netconf --update
-
- may be also useful to make sure a system is current (in sync with its
- configuration). The command
-
- netconf --status
-
- gives a report of what have to be done, while --update does it.
-
- The file /var/run/netconf.level stores the current operation mode and
- is used by the --update and --status netconf's option. This file is
- updated by "netconf --runlevel" and by //ssbbiinn//aasskkrruunnlleevveell at boot time.
