Cisco ubr924, how to disable IOS updates from Adelphia

Hi,

I do have one of those ubr924, and it has been connected with Adelphia
for almost 3 years, and it was working *uninterrupted* for more than
7-8 months.

Suddently, one day my service failed...and I could not connected
anymore to internet..after a went throught the engineers at customer
support (some of them are clueless), and they couldnt find the problem,
I spend couple long days getting into the problem/solution.

The problem was Adelphia had sent me an *updated* bios, that really was
not an update, it was an *outdated* bios. The version I had installed
was working with not problems for the last 3 years, and they decided to
send this outdated version.... Immediatelly I called them and scaled
the problem. They appreciated my troubleshooting efforts, and
immediatelly say that I had all the reason, and they believe that what
I had indicated was the problem, that they will talk with the
enginnering group. Later they contact me and told me the engineer group
had desided that the version they were sending was the best for most of
their customer mmm ..I asked myself: who come a very old version could
perform better that a new one, knowing that Cisco have published that
such version have bugs?

Well, I has been trying to see how I can disable my router from
Adelphia IOS updates, because Adelphia is sending me every day an
update (some days even twice) and after that my internet connection
start with problems during the first few minutes, and after that is
totally screw up, and I loss connection for good, until I again update
the IOS version with my version.

BTW, the IOS version that I am using and works properly is
ubr920-k8o3v6y5-mz.122-16.bin, and Adelphia is sending me the version
ubr920-k9v6y5-mz.122-5.bin

I already tried some commands, but they are not enabled on this IOS. I
tried changing the name of the IOS (my version) with the name of the
Adelphia version, and It did not work either.

In advance, many thanks for any suggestions or tips you can give me.

Regards,

Turcol

It's their network. They get to pick.

If you want to pick, you have to isolate your ubr924 from their network by
putting it on the other side of a router.

Not familiar with the UBR924, but - if you can determine the IP port
Adelphia is using to send the update, then could you block that port in
IOS?

The update is done when Adelphia send a signal to the reboot the UBR924
and add the following line to the config file, under the interface
cable-modem0:
cable-modem boot file ubr920-k9v6y5-mz.122-5.bin 68.168.0.19
where 68.168.0.19 is the ip address of Adelphia tftp.

I coudl try to block the port 69 (tftp) however I doubt that works,
because the router (UBR924) execute the config file before to go to the
filter level, where I can tru to stop any tftp traffic

This is all done through DOCSIS and it's unlikely that you will
be able to prevent it from happening. It's been a while since I used
mine, gave up on it really after moving. It was working fine with Time
Warner on the east coast but never worked right with Comcast in mid-west.
I had to upgrade to a certain IOS before TWC worked because they were
trying to set a bunch of crap via SNMP that the previous IOS knew
nothing about. I suspect that it didn't work when I switched to Comcast
due to similar issues but didn't have time to mess with it. One of the
techs thought it was possibly due to them going from QAM 64 line coding
to QAM 256 (more bandwidth) recently, but I checked and the UBR924 does
in fact support QAM 256 so that wasn't it.

These are great, they work well, have a couple of H.323 phone
ports if you want to mess with getting those working, do real routing
and tricks that are not possible with "consumer friendly" routers. The
drawback is that they're usually never "officially supported" by any
cable providers these days and even if you get it working your luck will
probably eventually run out. Even though DOCSIS is a standard, there
seem to be enough variables in the management side, that your
modem/router may not work right depending on how much they try to
"mangage" (or, is that mangle?) it.

My advice, if you want to stick with Cisco for the power (and
quirks) of IOS, is to go find a nice cheap dual ethernet Cisco 8xx,
16xx, or maybe even an old 2514 (if you like to hear fan noise) and
stick that behind a Motorola SB5100 or similar.
