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
+
