do atelnet boot log and see what the ip is for the tftp cfg server and try to download thaT FROM THE ISP SERVER.
It looks like the real config file name is obscured. Meanwhile, when I try to tftp from the server for 'd;kfoA,.iye' I am getting a file not found...

MAX CPE per CM is being set to 32 Ok, I got the config file opened using vultureware. See attached. I assume I need to modify as needed. The next question is what do I use for a passphrase when saving?

The passphrase is called the shared secret by the ISP's and I don't know of anyway to get it... unless you know the private snmp string, then maybe you could download the config from the CMTS and take a look around and find the shared secret. But that is another thing all together.
So the issue then is that I can't get this shared passphrase. How is it that I was able to open the file without a passphrase?
Does this leave me pretty much stuck? -- I don't think I am going to try getting into the CMTS. It's Docsis 1.0.... fyi Thanks,

so - I found the community string. The shared secret is a different thing correct?
In any case - this is still docsis 1.0. Isn't there a chance of uncapping this effing thing. (sb5101i) (28-08-2012, 03:43 PM)sinusoid Wrote: so - I found the community string. The shared secret is a different thing correct? Alright, it is pretty clear to me the shared secret is dynamic. ABMJR said this before, but I wasn't far enough in my learning to understand. So 1. Forcing config is out 2. tftp is out. Is option 3 going after the cmts? |
