Hrmmm, I guess I would be an "MS trained" person, yet I know what an RFC is.
Matter of fact, that is a core subject of MS training.
What RFCs has MS broken?

I know port 69, UDP, is used for TFTP.
I am just questioning the usage of that port by a provider who SHOULD know it could be used for nefarious purposes.
Any VoIP provider should use an unregistered port for their "updates" until they feel they are established enough to register their own port.
Unless of course they own the network and can block the port, yet update firmware all the same.
It all goes back to the fact that you get what you pay for.

| Hmmm...what the hell is an RFC?
It a computer acronym (gee, bet you didn't see that coming) that stands for Remote Function Call. It basically defines what the purpose is given to a port or range of ports. When you break an RFC you are plugging into a port that is not being used for its purpose.
and what RFCs has MS broken. Well, honestly....I have no clue how many because the Net+ Certified and the certification exam core test didn't have it.
But honestly, I would love to know how many just to get a good laugh.

1 edit | TFTP (port 69) is used to provision and provide firmware upgrades to the VoIP endpoint (analog phone adapter). TFTP is giving way to HTTP and HTTPS as the preferred method (by service providers) to manage VoIP end points. These protocols tend to work much better when a home or office network is supporting the VoIP endpoint connected to the LAN. CNET readers would have been better served if this information was included. | |

| Re: wtf mate Also some network devices (cablemodems perhaps?) TFTP their configuration files from a server. Usually that would be the device using a dst UDP port of 69 (and something else for the src, meaning the dst UDP port for the server->dev traffic), but still...UDP port 69??? jeesh. What a screwup, AT&T.

Twentynine Palms, CA | I just spoke with a Vonage tech and was told that Vonage has a workaround for this issue. I just had my firmware upgraded, even though I use Adelphia Powerlink (one of the ISPs blocking port 69).
