Have any of you prepped or read up on the cable haunt vulnerability? It has to be executed from behind the cable modem but there is a pretty good article here
I am hoping someone here has a solution. We have a rogue modem we have no idea where it is. It was a customers 6 years ago and is somewhere on our network. Problem is it never connects to get the disabled config it just harasses our cmts.
It pollutes the log files so it makes syslogging worthless when we want to identify any other issues.
Is there some way to ignore this modem completely?
I have an odd scenario in which ONLY 16+24 ch Arris modems will not get past init(o) when a 16 channel bonding group is added to the running config of a Cisco 10K (20x20, PRE4).
All non-arris modems (Motorola, SMC, Netgear) connect/bonds to the 16 channels with no issues whatsoever. If changed to a lower group of channels in the interface, wideband, and fiber nodes, the modems will connect 8x4 no problem.
The models in questions are SBG10, DG2460A. I am going to upgrade the firmware (SCI3) tonight to see if that helps.
Any thoughts? Thanks in advance!
I was running Wireshark to work on something related to our internal network, when I noticed a bunch of ARP requests coming from one of 6 CMTSes. None of the other CMTSes are doing it. In wireshark they show up as a "Who has XXX.XXX.XXX.XXX? Tell XXX.XXX.XXX.XXX"
Any thoughts as to how to stop it from doing that?
Someone here can tell me that I use to be able to provide telephony through mta cable modem, I currently use isc dhcpd and everything is fine with my c3, now I want to implement the telephony but I don't know what I need or rather what software could use or some way you do it.
I will be grateful.
We are having issues with load balancing in Docsis 2 modems. The wired only cable modems change channels and then the customer router loses connection and requires a reboot of their device. Previously I could find some modems where it happened at 5 minutes on the dot.
1. Is there ANY way to log this activity so we can see it happening?
2. What are all the different load balancing methods and their affect?
we are using DOCSIS Configuration File creator, version 0.9.6 and I have an issue with OIDs.
I try to implement the MTA config for Ubee EVW32C and have the working template from a colleague.
When I want to compile it with docsis -p config.cfg it returns the error.
/* Error: Can't find oid sipEndPntConfigUserId.9 at line 4 */
encode_vbind: Unknown Object Identifier (Sub-id not found: (top) -> 1)
