Linux network configuration
The built-in Ethernet card is not supported in the 2.2.15 kernel,
however support is present in the 2.2.17 and onwards kernels. A driver is available. Refer to Fred Maciel's page
for more details.
The Mandrake 8.0 installation kernel 2.4.3 has support for the
3c59x network card by default.
Supporting multiple IP addresses
The whole point of a laptop is to be portable. But most computers have
only one network address assigned to them, so how can they move around
and plug into different networks? While it is true that at any one
time a computer can only have one IP address, that address can change
at any point!
My home network configuration is configured using a DHCP server from
my Linksys firewall. I use two simple shell scripts to jump between the
home configuration and my work configuration. The first script sets
the configuration for in work:
#!/bin/csh
# Switch to a config for docked at HP
#
/etc/init.d/postfix stop
/etc/init.d/network stop
cp /etc/X11/XF86Config.docked /etc/X11/XF86Config
cp /etc/sysconfig/network.hp /etc/sysconfig/network
cp /etc/sysconfig/network-scripts/hp /etc/sysconfig/network-scripts/ifcfg-eth0
cp /etc/resolv.conf.hp /etc/resolv.conf
cp /etc/postfix/main.cf.hp /etc/postfix/main.cf
/etc/init.d/network start
/etc/init.d/postfix start
and this script sets the configuration for home:
#!/bin/csh
# Switch to a config for Home
#
/etc/init.d/postfix stop
/etc/init.d/network stop
cp /etc/X11/XF86Config.laptop /etc/X11/XF86Config
cp /etc/sysconfig/network.athome /etc/sysconfig/network
cp /etc/sysconfig/network-scripts/athome /etc/sysconfig/network-scripts/ifcfg-eth0
cp /etc/resolv.conf.athome /etc/resolv.conf
cp /etc/postfix/main.cf.athome /etc/postfix/main.cf
/etc/init.d/network start
/etc/init.d/postfix start
