PS: I tried stopping and then restarting ACS from within ACS itself.

Then, I did netstat -na again to see if that fixed the problem.

Unfortunately, the Tacacs+ port was still being listened to at addrsss
0.0.0.0, not 10.0.0.100.

BTW, I don't think this should make a difference but this box has 2 nic's,
one which is used for RDP access from anywhere and another

Which is used in the practice lab.

Thanks, Tim

just because the aaa box is up dosent mean radius/tacacs is running on it
which is what its telling you with the debug message:
"AAA authentication server not accessible"
id make sure aaa is running and you have the ports correct on the server and
the router (old 1812 vs new 1645). netstat -na on your aaa box then nmap the
ports radius/tacacs is running on to make sure you can access it.

Hey guys,
 
This is driving me batty.
 
I setup aaa authen but it's failing.
 
Here's the debug output:
 
%PIX-6-113014: AAA authentication server not accessible : server =

PIX(config)# ping 10.0.0.100

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.0.0.100, timeout is 2 seconds:

!!!!!
 
Why would the debug say "AAA authen server not accessible when it is?
 
I thought maybe the shared key wasn't correct or maybe the ip addresses
weren't correct but I checked them and they're all correct.
 
Thanks, Tim
