9.13. Laptop Extension Cards: PCMCIA
PCMCIA card drivers are built into the kernel as modules since kernel version 2.6.13. On a system running Debian
Squeeze, you simply have to install the user space support contained in the
pcmciautils package.
Every time you connect or remove a card, the daemon configures or deconfigures it, by executing a script in the
/etc/pcmcia/
directory, which gets its settings from the
/etc/pcmcia/*.opts
files. These files have been slightly adapted to work with a Debian system; the configuration of the network is delegated to
ifup
if the
/etc/pcmcia/network.opts
file does not take care of it. The same is true for configuration of a wireless network, which can be specified in
/etc/network/interfaces
instead of
/etc/pcmcia/wireless.opts
. The
/usr/share/doc/wireless-tools/README.Debian
file also describes the syntax to use.
After this overview of basic services common to many Unix systems, we will focus on the environment of the administered machines: the network. Many services are required for the network to work properly. They will be discussed in the next chapter.
