By creating network profiles, you can easily select different network configurations at boot or at run time from the console.
 
== Setting up the profiles ==
 
As root: Duplicate the sample profile at /etc/network-profiles/, and save it as a describing name:
 
cd /etc/network-profiles
 
cp ./template home
 
Now edit this new profile (e.g. home) in your favorite editor (i.e. emacs) to fit your needs. Below is a very simple profile example to connect to a wireless network.
 
Using the profile below is equal to using:
 
iwconfig eth1 essid home_wlan key F4DE214AA8
 
dhcpcd -s 192.168.1.105 eth1
 
And here the profile script:
 
DESCRIPTION="Wireless profile at home"
 
 
# Network Settings
 
INTERFACE=eth1
 
HOSTNAME=myhost
 
 
# Interface Settings (use IFOPTS="dhcp" for DHCP)
 
IFOPTS="dhcp"
 
 
# Wireless Settings (optional)
 
ESSID=home_wlan
 
KEY=F4DE214AA8
 
IWOPTS="essid $ESSID key $KEY"
 
DHCPCD_ARGS="-s 192.168.1.105"
 
Create as many different profiles as you need.
 
 
 
Last, be sure to comment out any entry in your rc.conf related to network interfaces other than "lo": the lines with eth0="", gateway="" and ROUTES=() should be commented, while:
 
INTERFACES=(lo)
 
 
 
== Select profile at boot time using GRUB ==
 
Selecting a certain profile at boot time is handy, and is easily accomplished using [[GRUB]].
 
Edit the /boot/grub/menu.lst, duplicate your standard boot section and add NET=<profile name> to the kernel line e.g:
 
# (0) Arch Linux
 
title  Arch Linux (Standard) [/boot/vmlinuz26]
 
root  (hd0,0)
 
kernel /vmlinuz26 root=/dev/sda3 ro vga=794
 
initrd /kernel26.img
 
 
# (1) Arch Linux
 
title  Arch Linux (Wireless at home) [/boot/vmlinuz26]
 
root  (hd0,0)
 
kernel /vmlinuz26 root=/dev/sda3 ro vga=794 NET=home
 
initrd /kernel26.img
 
 
 
== Select profile at boot time using dialog ==
 
You can select network profile using the dialog package. Simply edit /etc/rc.conf file and comment out the line:
 
NET_PROFILES=(menu)
 
Remind that there is a 5 secs timeout for the dialog menu, after which the first profile in alphabetical order is enabled.
 
 
 
== Change profile at run time ==
 
If you want to change the profile after boot, simply type
 
netcfg home
