README

        
Method 1 ------------------------------------------------------

The following config will allow the Linux machine (10.1.1.2) to read

the IP address from the DHCP interface on the Cisco router (eth0) as

user ddclient.  Since ddclient is configured with a priv level of 1 it

cannot do anything except look at the routers stats, ip addresses,

etc.  This should be pretty harmless even if ddclient's password were

to be discovered.

This has been tested with Cisco IOS 12.1(5)T5 running on a Cisco 2621

router.

Cisco Router Config (Assuming eth0 is DHCP interface)

-----------------------------------------------------

user ddclient password password

user ddclient priv 1

ip http auth local

ip http access-class 99

ip http port 1021

ip http server

access-list 99 permit host 10.1.1.2

DDClient Config

---------------------------------------------------

use=cisco, fw=10.1.1.1, if=eth0, fw-login=ddclient, fw-password=password

Method 2 ------------------------------------------------------

use=fw

fw=192.168.1.1/exec/show/interfaces/CR

fw-skip=FastEthernet0/0

fw-login=ddclient

fw-password=xxxxxxxx
