Cisco DPC3208 / EPC3208(G) - howto get a shell?

[MaCXyLo]

Hi,
i am tired with the Router Obligation of my provider.
I have a Cisco EPC3208(G).
This device would be selled by my provider as a "modem" but it's a router with a configurable firewall.
I found out, that this device have 2. local Ip Adresses:
192.168.0.1
192.168.100.1

Howto get a shell on this device?
I start a portscanner, found out that on 192.168.100.1 is a snmp port open. I also get a list when i start snmpwalk - but i don't see any option to activate the shell.

Are people on this board that have the same device and some experience ?

I have a second device (same model series) - some unsoldered ports are available.

Quote on manual:
"SNMPv3, SNMPv2, and SNMPv1, Telnet /SSH with configurable user ID and password, internal log, and external Syslog support"

hi dude,

wow, this thread is so amazing.....
a one liner after the next........
searching since months to get more informations about my modem and struggle me
have original documentations and firmware images from Arris cable modems, got the next time official documents from cisco
my plan was to release that hot shit on your board.
and the only thing that i heard from you is contempt.
Why is there so many imagination from your site?
time of universal genius is past - the inet works together...
We can't control every single system, that will de facto never fuckin' happens, so stop this negative emotions.
My strength are pracitcal works like soldering, repairing things like washing machines, cars and other stuff.
i worked for 2 ISP's as an service technician and have skills with phone lines, koax (main focus) and fibre technologies.
I can told you many stuff about the guidelines, constructions, used gauges and physical errors of a koax network on the street and the houses - that was my job.
The point is, that i have expert skills, but in other areas - so stop kidding me.
experts of different areas must work together to find solutions.


my motivation:
in germany are legal purposes that allows my provider to control completly my LAN.
So i start my researches about that topic.
Is there anyone with willingness to support my researches?
if not, simply close the thread if the questions are under your high sensitive intellect level. thanks.
