auto-dhcp in grml/debian-based?

Can't seem to figure out how grml is stopping the auto-dhcp during boot
by default in grml network is disabled
I tried init.d, inittab, or whatever
I cannot seem to find anything??

I need eth0 to come up automatically at boot
grml, for some reason won't remember my net setup and must re-setup at every boot??!

How can I make it do that?
thanks

Hey Linus,how ya doing?
If grml is the same as Debian you need to look at /etc/network/interfaces
Here's a sample from mine,running ethernet with dhcp:

ade@Pc1:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

How does this compare to yours?.
Some people say to change allow-hotplug for auto,but i found this slowed my connection at boot up.So i now leave it as it is.
Have a look,let us know how you get on.

Completely off topic,check this internet radio site:

Well
here's /etc/network/interfaces

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

I added allow-hotplug eth0
as you said
this stil didn't work and I have to still start the network manually via grml-network

BUT, I found this in /etc/network it's called "interfaces.example"

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# Also check out /usr/share/doc/ifupdown/examples/network-interfaces.gz

# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback

So, which of those should I uncomment for auto-eth0?
this one

or this one

# iface dhcp inet dhcp

or this one?

I just want simple dhcp auto connect at boot
thanks for your help!@

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

You've got double entry's for eth0!.

Try it like mine:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

If that doesn't work,try changing allow-hotplug for auto

Unfortunetly, there seems to be a script that runs at startup which somehow rewrites the "interfaces" file
even running persistent, if I change the file as root, it still reverts back to only loopback, and nno auto-eth0

I will now unsquashfs the grml.squashfs and edit stuff and mksquashfs that B#@$%!
LOL

LOL
this ones gonna be fun

OK, so I attempted to unsquashfs the grml-medium.squashfs
@$%^%...dink

"no SQUASHFS superblock on grml-medium.squashfs"

what?
google is your friend

http://www.splitbrain.org/blog/2009-...b_without_a_cd

anyway, it says you need "unsquashfs-lzma", which I found out is
included in slax-6.1.2 /tools folder

so, I was in pmagic, so I downloaded unsquashfs-lzma and unsquashed it

Now, I changed the /etc/network/interfaces to what Trooper told me above
I then booted off USB(persistent) and edited bootline "nopersistent"
to get a fresh boot

OK, that worked great!

PROBLEM
I then rebooted "persistent" with my saved /etc/stuff and guess what?
No DHCP!

LOL
I'll edit that and see what's up
