Wired network

Question

I just installed Arch from Opensuse 11 following this guide  http://wiki.archlinux.org/index.php/Ins … ting_Linux .
I installed Gnome 2.24 desktop through OpenSuse also. However, when I log into Arch, the internet (wired) is not working.
I have installed networkmanager. In order to get it working, i messed around with /etc/rc.conf a lot. And now the internet is even more messed up.
As a first time user of Arch, I have no idea what wrong I have done. Now I cannot even install packages onto Arch through opensuse chroot  /bin/bash -ing into the Arch system. The internet on opensuse is working fine, but not on Arch.
I have read the myriad of guides on the Arch site regarding networking and network manager. I would like to shift to wicd now.
However, if the problem can be solved through networkmanager itself, then I won't shift.
So here is my question:
Say I have a wired eth0 connection whose IP address 10.10.1x.xx and primary DNS is 10.10.0.x and the subnet mask is 255.255.xxx.xxx.
What should be my entry in rc.conf and hosts files? (I do not know how to find my broadcast address).
at present my rc.conf reads:
HOSTNAME="myhost"
# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available interfaces.
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES
# - prefix an entry in INTERFACES with a ! to disable it
# - no hyphens in your interface names - Bash doesn't like it
# DHCP: Set your interface to "dhcp" (eth0="dhcp")
# Wireless: See network profiles below
eth0="eth0 10.10.xx.x netmask 255.255.xxx.xxx broadcast 10.10.xx.xx"
INTERFACES=(lo !eth0 !wlan0 wmaster0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 10.10.xx.xx"
ROUTES=(gateway)
DAEMONS=(syslog-ng !network netfs @crond avahi-daemon avahi-dnsconfd hal dbus dhcdbd networkmanager gdm @fam dhclient)
and my /etc/hosts/ file reads
# /etc/hosts: static lookup table for host names
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 localhost.localdomain localhost
# End of file
I also am very confused about what to enable and disable in rc.conf, for the networkmanager to work.
Could someone please please help me out with this setup? I have read a lot on the site and gotten more confused. I would really appreciate if you could just walk me through this step.
Thanks a ton in advance.

OK. Let's make things simpler.
Here is a sample of a working /etc/rc.d file.
/etc/rc.conf - Main Configuration for Arch Linux
# LOCALIZATION
# LOCALE: available languages can be listed with the 'locale -a' command
# HARDWARECLOCK: set to "UTC" or "localtime"
# TIMEZONE: timezones are found in /usr/share/zoneinfo
# KEYMAP: keymaps are found in /usr/share/kbd/keymaps
# CONSOLEFONT: found in /usr/share/kbd/consolefonts (only needed for non-US)
# CONSOLEMAP: found in /usr/share/kbd/consoletrans
# USECOLOR: use ANSI color sequences in startup messages
LOCALE="en_CA.utf8"
HARDWARECLOCK="UTC"
TIMEZONE="Canada/Eastern"
KEYMAP="us"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"
# HARDWARE
# Scan hardware and load required modules at bootup
MOD_AUTOLOAD="yes"
# Module Blacklist - modules in this list will never be loaded by udev
MOD_BLACKLIST=(snd-pcsp)
# Modules to load at boot-up (in this order)
# - prefix a module with a ! to blacklist it
MODULES=(skge vboxdrv)
# Scan for LVM volume groups at startup, required if you use LVM
USELVM="no"
# NETWORKING
HOSTNAME="dragonfly"
# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available
# interfaces.
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES
# - prefix an entry in INTERFACES with a ! to disable it
# - no hyphens in your interface names - Bash doesn't like it
# Note: to use DHCP, set your interface to be "dhcp" (eth0="dhcp")
lo="lo 127.0.0.1"
eth0="eth0 192.168.1.21 netmask 255.255.255.0 broadcast 192.168.1.255"
INTERFACES=(lo eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 192.168.1.1"
ROUTES=(gateway)
# Enable these network profiles at boot-up. These are only useful
# if you happen to need multiple network configurations (ie, laptop users)
# - set to 'menu' to present a menu during boot-up (dialog package required)
# - prefix an entry with a ! to disable it
# Network profiles are found in /etc/network-profiles
#NET_PROFILES=(main)
# DAEMONS
# Daemons to start at boot-up (in this order)
# - prefix a daemon with a ! to disable it
# - prefix a daemon with a @ to start it up in the background
DAEMONS=(syslog-ng network @cups ntpd @crond @alsa @hal gdm)
# End of file
A few things to notice:
1. the line MODULES=(skge vboxdrv) will be different in your machine, so for starters; unless you know you need some specific modules live it blank eg: MODULES=()
2. HOSTNAME='THE_NAME_OF_YOUR_MACHINE' is the name you give the machine to identify it in the network. I called mine dragonfly.
3. Notice that I', using the 192.168. range (as opposed to 10.10.x.x) so in your case just use the IP address values you chose for your network and notice also that the gateway **has** a value.
4. In the DAEMONS line you will see some applications preceded by '@' like @cups. This loads the appps in the background which will speed up your boot time but you  **do not have ** to use it that way and you can safely remove the '@' symbol without causing any problems.
Use this file as an example (or even copy and paste it into your system) to modify your /etc/rc.conf so that your system will work.
