Also, look at the /etc/rc.d/rc.local file. That's a script that is automatically run by the init script, as "root," before your system starts the X-server. It's designed for stuff like you want to do, Here, for example is my rc.local script for this laptop:
Code:
$ sudo cat /etc/rc.d/rc.local
[sudo] password for Peter:
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
local_dir="/etc/rc.d/"
touch /var/lock/subsys/local
#-----------------------------
# Turn off all output
#exec &>/dev/null
# Load the local function definitions
__local=T
. ${local_dir}/rc.local_functions
echo
echo -----------------------------------------------------
echo Starting $0
# Connect to the TSS3 network if it's available
connect_to TSS3
# Activate and mount any available, unmounted, volume groups with mount points in /etc/fstab
vg_activate
# Mount any "noauto" devices listed in /etc/fstab that exist and are not already mounted
mount_noauto
# Mount any "noauto" cifs devices
mount_cifs
# Mount up to max_loop ISO files located in /ISO under /mnt/ISO/
mount_iso
echo -----------------------------------------------------
echo
<edit>
Oh, note that that script uses my rc.local_functions. Since you're doing network connection stuff, here's the part of that script that connects my laptop to my local network. (Note the sucmd function that let's me run the privileged stuff in the other functions if, for some reason, I need to rerun one of them during without rebooting.)

$ cat /etc/rc.d/rc.local_functions
