Are there any hints that the cable-modem could coexist in a modern network? i.e. if a cable-network engineer wanted to play ball, could they carve out some frequences for NABU without taking down DOCSIS?
Cable Modem Hacking Kit 64 Bitl
All cable modem at startup will look for the image of a "file" in which to do all the load limit setting and download speed is the speed limit is set. This "stored image file" on the ISP`s TFTP server. Modem can be configured with pre-ISP`s IP address of the TFTP server and the name of the image file to be downloaded. If the modem is booting the server and the TFTP request to download an image file from the TFTP server is in accordance with this speed limit we had set.
You can view the back of the modem to obtain this MAC address or you can log in to the cable modem with Web Browser hxxp: // 192.168.100.1 /. This is the internal HTML pages are stored DOCSIS cable modem (SB5100, SB4100 and SB3100) which gives you more information about important settings. Unless it is disabled by your ISP. This feature could be completely turned off by your ISP.
a) There is a program called "Weird query.exe BOOTP request packet solution program that will tell you everything you need to know, without all these additional steps. It will display the image file, the TFTP server address, the only you need to get started.To use this BOOTP query tool, you need the MAC address of the cable modem
Among these, what we need is:Configuring the TFTP server = 194. . .. 90 (replace this with yours in every doc)= The Isrr.bin configuration file name (replace with what you want while in the doc)YFragments IP created = 0Address.10.xxx.xxx.xxx IP = 10.xxx.xxx.xxxAddress.192.168 .100.1 IP = 192.168.100.1 (cable modem's IP address, (replace this with your own in every doc)IP-a-Sync.10.xxx.xxx.xxx = 2
TPC configuration the followingIP TCP values : 194. . . 90 (replace with the TFTP server from the ISP)Mask: 255.255.255.0Gateway: 192.168.100.1 (replace with a cable modem IP address)
In order to be compatible with the Cox network, the 3rd party modem you choose needs to be a DOCSIS 3.1 cable modem with integrated Wi-Fi capabilities, also known as a gateway, that is capable of broadcasting dual-band 802.11-AC Wi-Fi or higher.
We immediately identified what looked like two UART pin-out. When auto-identifying baud rate, we noticed that the first pin-out is live while the other is not. Usually, cable modems have two separate systems: a Media Server (MS) running Linux and a Cable Modem (CM) real-time operating system running either eCOS or VxWorks. It turns out that this specific model does not have a Media Server component.
VOO cable modems web administration interface is not directly exposed to the public Internet and can only be reached from customers local area network. However, attackers could target cable modems by getting customers to open a malicious web page. The malicious web page would execute JavaScript code exploiting the buffer overflow to gain remote code execution. To do so, the malicious code would need to bypass two security mechanisms: Same-origin Policy, and enforced authentication and authorization.
We discovered that affected devices are vulnerable to DNS rebinding attacks, which can be used to bypass the Same-origin policy. We also identified ways to obtain valid credentials due to an information leak affecting the Universal Plug and Play service exposed by the cable modem.
This distribution is for all devices scanned since the introduction of VOO cable modems. If we graph this distribution over time we observe a trend with Technicolor devices being introduced in 2016, with the distribution slowly reaching 50% by 2020. We do not know whether VOO customers are asked to replace their Netgear routers with Technicolor ones, but we will use this trend to calculate conservative estimates.
In this report, we successfully demonstrated that an attacker in wireless reception range of a VOO cable modem could successfully derive the default WPA2 pre-shared key and obtain unauthorized access to a customer wireless LAN. We also demonstrated that the web administration panel is vulnerable to buffer overflows. By chaining these two vulnerabilities, attackers could fully compromise any VOO cable modem by just being in reception range.
Default Credentials We recommend VOO to change these default credentials by using DOCSIS configuration files deployed to affected modems when they register on the network. Please note that these credentials can still be captured by someone with physical access to a cable modem serial console.
Side Note on Technicolor We did not look at the Technicolor TC7210.V cable modem provided by VOO for lack of having access to one. We therefore cannot say with enough confidence whether it is affected by similar issues or not.
I also make this modem using a CH340 clone of ESP8266.You must use a different flasher program from : -troubleshooting-guide/and then everytjing else is the same. The speed updated to 9600 and the power comes from the user port. I also add the reset 1-3 pin button and made the board vertical, saving space and for future option of connecting an LCD screen in top of the board. I was too impatient to wait for a ready board and I used a perforated board and I made the connections using cables. I didnt use the DCD connection to GPIO2 and everything works ok.
Stay connected with gateway and cable modems by choosing the right model to fit your needs. Some DSL gateway modems come with programmed security features, like firewalls for protection against hacking or data theft. Most models provide compatibility with popular computer operating systems, allowing for versatile use. Cable modems boast multiple downloads and upload channels, making them a good pick if you're streaming high-definition media or enjoying high-performance gaming. USB modems are a popular choice with students, digital nomads and frequent travelers because they're easier to pack, thanks to their compact, lightweight builds. When shopping for a cable modem, be sure to confirm its compatibility with your internet provider and other devices.
Enjoy optimized cable internet reception without the burden of monthly rental fees with modern cable modems. Their innovative features enable high download and upload speeds for maximized productivity. These modems come with ultra-fast Gigabit Ethernet ports for attachment of wireless routers that provide lag-free Wi-Fi connectivity. Some feature ports for the connection of antennas to improve the performance of your broadband. Others feature built-in Wi-Fi gigabit routers for shared high-speed internet to various smart or media devices. Cable modems come with multiple channels. Pick a model with more channels to get the fastest data rates. Cable modems often feature multiple network safeguards. Most models come with well-placed visible LED indicator lights that display whether there are connectivity issues. Many cable modems feature an intuitive management interface for easy Wi-Fi setup and management.
If your home area lacks reliable cable access, consider purchasing a DSL gateway modem for improved internet connectivity. These network transceivers allow ultra-fast internet access through phone lines, while optimizing the amount of data you can get from phone jacks without interruptions during calls. Most come as a DSL modem and router combo designed to save you space and reduce wire clutter. Many such models feature user-friendly setup wizards for speedy and convenient installation and use. DSL gateway modems also feature USB ports so you can plug in storage devices for Network Attached Storage (NAS) functionalities and enhanced media streaming.
These cables run from your modem or modem-router combo (known as a gateway) to the Ethernet ports on your online-enabled devices, like computers, laptops, or smart TVs. If your device doesn't have an Ethernet port built-in, you may be able to use a USB-to-Ethernet adapter.
The bigger and more complex your wired LAN, on the other hand, the higher your costs. If you're simply running an Ethernet cable to your Xbox One, you're looking at the price of only a single cable. But if you're a small business designing a safe, stable, and private network, you'll need modems, firewalls, servers, switches, and possibly even professional installation. As costs rise with each workstation that accesses your network, you could be looking at a sizable initial investment. 2ff7e9595c
