Cisco & Radius Authentication

Yay... If you have multiple devices from multiple vendors, Radius is a nice way to get them to talk together. This is how I got Radius working with my Cisco router.


1. Install IAS from add/remove programs
2. Launch IAS, create a new "Radius Client".
Friendly name can be whatever you want, I chose the name of my router.
IP is the device you want to connect to IP address.
Set the shared secret (something good, no less than 6 characters, 16 would be best, no spaces, dashes are ok)
3. Create a "Remote Access Policy".

I use the wizard one, seemed simple enough. For the policy name i just chose what i was connecting to. Ethernet; Group, added a new group in AD called "Network Admins". Chose MD5 (will change later); Finish.
4. Edit your new policy (properties), remove NAS-Port-Type and put in "NAS-IP-Address"; then put in the ip of your device.
5. Edit Profile; Authentication Tab, select PAP. Under EAP methods, remove MD5.
6. Advanced Tab; add Cisco-AV-Pair; Add "shell:priv-lvl=15" under Attribute value.


Now for the Cisco Part; what got me interested was tightening security on my router, so parts are from (Here)

aaa authentication login default group radius local-case
aaa authentication enable default group radius enable
aaa authorization commands 15 default group radius local

radius-server key password <-- change this to the shared secret you set up on the Radius Server

Ubuntu 8.04 LTS and Dell 700M

So "netbook's" seem all the rage these days, so i thought i would dust off my old Dell 700m, it's not quite as small as a current netbook, but it is nice and tiny.


My plans include putting in a nice little 32GB SSD drive, and upgrading the processor to a 2.10Ghz when they are ~20 (no rush, not a big difference in speed over the current 1.8Ghz Pentium M)


Anyway.. i installed Ubuntu on it, and it's been nice for surfing and basic tasks... but ran into a problem of it not shuting down properly. More like X was crashing...


There are a number of tricks out there to try and fix it, this one seems to make it happen less than any others.


First i shut off the splash screen's (edit /boot/grub/menu.lst)


then, in /etc/X11/xorg.conf, change:
Section "Device"
Identifier "Configured Video Device"
Driver "intel"
EndSection

to
Section "Device"
Identifier "Configured Video Device"
Driver "intel"
Option "ForceEnablePipeA" "true"
EndSection

it seems to make it better... we'll see!


EDIT: I'm including this link, as it has other options that might help on other hardware.
