Network-Scripts question

zmanods · 02-17-2007, 06:52 PM

I create a new file /etc/sysconfig/network-scripts/ifcfg-eth1 as follows:
ONBOOT=no
USERCTL=yes
PEERDNS=no
TYPE=Wireless
DEVICE=eth1
#HWADDR=xx:xx:xx:xx:xx:xx
BOOTPROTO=dhcp
#ESSID=xxxxxxx
#KEY='xxxxxxxxxxxxxxxxxxxxxxxxxx restricted'
MODE=Managed
RATE=Auto
PEERNTP=no

Question
I need to know how to find out the values for HWADDR, ESSID, KEY.

Explain like you would to a kid please

Thanks in advance.

The HWaddress is the MAC address of eth1. You can get that info from the first line of /sbin/ifconfig eth1.

The ESSID and KEY values are for the wireless network. Connect to your routers setup via a wired connection or another host and get it from the wireless status. For example, for a linksys router, http://192.168.1.1 ( it may use the https:// protocol instead and you may have changed the IP address from 192.168.1.1 ).

Consider using wpa_psk.

When i try to vi that file i see complete garbled text.

HWaddress is not really needed. I leave mine else because I have multiple cards that can use that interface.

If not using WEP then the KEY is not needed. The value here is the same you entered in your router if using WEP.

ESSID is the name of the network on the router. If no other wireless networks around you then this is not needed.

Run the command "sudo /sbin/ifconfig eth1". The hardware address is on the first line of output.

Code:

sudo /sbin/ifconfig wlan0
root's password:
wlan0     Link encap:Ethernet  HWaddr 00:90:4B:92:71:A1

$sudo /sbin/ifconfig wlan0
wlan0: error fetching interface information: Device not found

crap.

Use eth1 instead of wlan0. I demonstrated the command on my system as an example.
