Network connection management for Ubuntu

A long time ago, setting up a wireless network did not work, now make up for the holiday.

I'm using Ubuntu 7.10.

The X driver must be installed correctly.


The relationship between X programs:
Ifconfig, Iwconfig, IP, route, wpa_supplicant these are the underlying programs.

Network manager, Network-admin, Ifup, Ifdown is a higher-level call, they may call the underlying program, or implement the functionality of the underlying program, and may have extensions.

If you want to make network settings, in root mode.

X can view these through man:
interfaces, Wpa_supplicant, wpa_supplicant.conf, Ifconfig, Ifup, Ifdown, Iwconfig

The x/etc/network/interfaces settings are valid for Ifup, Ifdown, and Network-admin are set to set up the network connection. System Services (service networking) is actually the implementation of this file settings. Network Manager has a Nm-applet general in the tray has an icon, its manual configuration option is actually called Network-admin

Network Manager does not use the settings file/etc/network/interfaces, and network manager does not work if the file is set.

If the/etc/network/interfaces is set up and you want to manage the connection with network manager, you can remove the interface settings except lo in the interfaces file

* Last setup was unsuccessful because network manager needs my ndiswrapper driver to load ahead of time and add one line to the/etc/modules file: NDISwrapper. If you use Network-admin, the previous settings in the modules file must be deleted because NDISwrapper is in the/etc/modprobe.d/ NDISwrapper has been set up for more detailed ndiswrapper information view here (en, no translation)

* In fact, there are a lot of tools to set up the connection, such as WICD

* Generally speaking network Manager is sufficient for connection settings, and if you want to manually set up, it is best to uninstall network manager to avoid conflicts:
sudo aptitude purge Network-manager network-manager-gnome

Set words, see Manual is almost, copy someone else's code, wrong don't know why

* Other: Find the answer to find the fastest or to the product responsible for the site, check its documentation. Like Ubuntu wiki, Debian User manual, reference.

A long time ago, using a different site to record different information, found that this is inconvenient, and sometimes to connect the relevant information to know the key, or to integrate.
