But we could trade putting content on V6 for them if they make their network do multicast for us. Deal? brandon

RFC for Mask/Gateway
by Scott Altman 05 Aug '05

05 Aug '05

Apologies upfront for my not being able to successfully google this on my own... Is there an RFC or other standard that specifies that IPv4 connected devices must support the concepts of Subnet Mask and Default Gateway? I have a kludgy (<- technical term) vendor that has developed a custom AP that only has an IP address. Whilst cleaning up our network and turning off proxy-arp, lo and behold, it isn't really all that functional anymore. Thanks in advance, replies off-list welcome. - Scott

FCC puts DSL on same footing as cable service
by Fergie (Paul Ferguson) 05 Aug '05

05 Aug '05

Marguerite Reardon writes in the C|Net News Broadband Blog: [snip] The Federal Communications Commission on Friday did away with old rules that require phone companies to share their infrastructure with Internet service providers. The new framework puts DSL service in line with cable modem services. Recently, the U.S. Supreme Court upheld the FCC's interpretation of cable modem service as an "information" service, which means it isn't required to share its infrastructure with competitors. The new rules could hurt ISPs such as EarthLink, which will be forced to negotiate wholesale deals with existing DSL providers. But DSL providers won't get off scott free. DSL providers will still be required to comply with wire tapping rules and disability requirements. And DSL providers will still contribute to the Universal Service Fund, at least for the next 270 days until the FCC can figure out another way to keep USF funded.

Your router/switch may be less secure than you think

Michael Lynn is not the only person out there reverse engineering routers, switches, printers and other embedded systems. Lynn's presentation gave far less info than other people have published. One person has published detailed instructions on how to exploit IOS including code to do the exploit and an example scenario of how to use it. Contrary to what some may be worrying about, it it not the GSRs that are most at risk. It is those old 2500's that are connected to your customers. Imagine that one of those customer routers is exploited, the hacker installs a tunnel, and then proceeds to anonymously probe the customer's network. This is the real risk and it may very well be happening right now to one of your customers. The following is one of the slides from a black hat presentation which is basically a primer on reverse engineering and exploiting embedded systems. --------8X---------------------- How to protect Cisco specific ! Have no overflows in IOS ! Keep your IOS up to date ! Do not run unneeded services (TFTP) ! Tell your IDS about it. Signature: \xFD\x01\x10\xDF\xAB\x12\x34\xCD ! debug sanity might stop less experienced attackers ! The hard way: config-register 0x00 ! Perform logging on a separate segment ! Protect your syslog host ---------8X----------------------- Other slides in the presentation talk about exploits in networked HP printers and various other brands of switches and routers. I think this should serve as a wakeup call to the entire industry that current engineering practices are not good enough any more. We should all be looking to the security auditing work done by the OpenBSD team for an example of how systems can be cleaned up, fixed, and locked down if there is a will to do so. --Michael Dillon

Just another lesson: Read the instructions before installing....
