Update firmware for older Dell servers

Download the CentOS LiveDVD from here: http://linux.dell.com/files/openmanage-contributions/om-firmware-live/

next, copy it to a usb drive with dd:

sudo dd if=<path to CentOS iso> of=/dev/<my usb drive> bs=4096

This image should have all the latest firmware built into it. I used this to update BMC firmware for the Dell R900.

There is a blog by Dell about this procedure as well, shown here:

OpenWRT on DIR 601 Rev B1

Have to use the NA file, because the other file won't get recognized as firmware.

Once that is done, telnet into 192.168.1.1 to set up OpenWRT

uci del wireless.@wifi-device[0].disabled

uci del wireless.@wifi-iface[0].network

uci set wireless.@wifi-iface[0].mode=sta

uci commit wireless

wifi

iw wlan0 scan

then follow the steps here

http://wiki.openwrt.org/doc/recipes/routedclient#using.masquerade

Make sure to change the LAN settings to a subnet not shared by the "mothership" router! And also encryption type is PSK2 for WPA/WPA2 mixed mode - iw wlan0 scan did not show the same output as the steps on the page.

To change the default LAN IP of the D-Link network, simply edit /etc/config/network
