Hope some one can help me out, I have a digital signage unit that use simple file networking. This lets the unit fetch new content from an FTP server I believe, but the catch is it has to be setup with an anonymous login with out password... not very SAFE. So what I would like to find out, is it a possibility to set up an FTP server with an anonymous login along with a MAC address control, kinda like you can do with an open wireless NETWORK?

Look forward your help,

ChandlerThe problem would be that the mac address is non transferrable and the MAC address sensed would only be devices that connect locally to the router, and it is sensed on the switch side of the router and not the service port to the modem. If you were able to sense on the internet service port that the modem connects to, you will only be able to sense the mac address of that of the modem and no further.

If you had a computer CONNECTED to the digital signage unit that gets updated from another system, thats your best bet.

I set up a similar, dedicated computer setup to be able to edit a very old phone system that required a modem / serial connection to edit parameters. Some people USED Serial to Ethernet Adapters to remote access the old phone system according to the contractor who serviced the unit, which are not the most secure! I chose to put an old Pentium II 266Mhz computer at the site with a Null Cable between the phone system and Com1 of the computer running Windows XP Pro and would RDP into this system to edit the phone system that was old but cost too much to replace.

*The most secure method would be to have a dedicated computer to authenticate with across the web using RDP, GotomyPC, or another service, and then have the insecure connection to the digital signage unit to a 2nd network adapter with a cross over cable. So you would be able to remote to this computer, and send the file across to update the digital signage unit.Cheers for the quick reply! I have already done the trick with have a computer sitting with the unit, I just wanted to avoid have to take both the unit and a computer, as it is a rental unit, which does a lot of travelling. Oh well for now it seems like that is what I'll have to do! The annoying THING is, the unit is bt bright sign, and along with the simple file networking, they have their own remote network, which is password protected. So the unit is able to, but they have written the firmware to only make their paid for network safe
