aDSL routers

[exocet () EUROPA COM (Brad Zimmerman)]

This is also true on USWest's Cisco 675.  Password is (hit the enter
key)...  However, as far as I know, all ISP's using Cisco 675's are set
into bridging mode, which doesn't allow any remote access to the Cisco
675, save the serial cable.

Older USWest equipment, the Netspeed 202 and 204, used a default user name
(root) and a default password is (hit the Enter key)...

For both routers, the Netspeed and Cisco, the default password/login is listed right in the manual, for anyone to see.

In the future, I believe USWest intends to have customers set their Cisco
675's into routing mode.  Or, at the very least, ISP's will begin supporting PPP over Ethernet, which means the Cisco 
routers are set into routing mode, which will make many thousand customers vulnerable due to unauthorized remote 
access.  I believe (but not sure) that Verio has the ability to let customers set their modems into routing mode (using 
PPP over Ethernet)...

USWest *has* detailed changes to the Cisco 675, noting it's ability to do
do PPP over Ethernet along with what is required at the ISP end to perform
PPP over Ethernet.
