Networking in PPCRCD
WARNING as a first thing
By default sshd server is started, to have easy access if
console isn't working. You should disable it, with option nosshd
if you are in unsecure network. Or change root password, after
booting it is ' ppcrcd '.
Bringing up network on boot
Recently udev has complicated things a little, as
it detects network cards dinamically, but order of interfaces may
change between one and annother boot. That's why I support two ways to
Old way, disabling udev automation
This way still works, but shouldn't be used anymore.
Use new way as I think most problems are solved already.
New way, dynamic interfaces asignment by udev
If you specify eth= option in kernel cmdline or
nvram udev when finds some interface, checks its driver ethtool -i
$IF and uses your configuration for it. Using this way you can
configure only very simple connections.
For more complicated interface configuration one used to
save /etc/sysconfig/interfaces/ifcfg-eth0 in configuration
file. But it depends on interface, and we normally can't be sure if it
will be detected same way next time. The only situation you can be sure
about it is when you have only one network card. But remember, FireWire
is detected as network too.
To solve this problem save your configuration to
/etc/sysconfig/interfaces/ <module> .ifcfg ,
without specyfying DEVICE in file. It will be moved by udev script to
correct ifcfg- $IF file, and appropiate DEVICE= $IF
option will be added.
