Remoting the K2
Locked

Hi Stephen. Check out DynDNS. They provide a free service that
correlates an alphanumeric IP alias address with your currently assigned numeric IP address. A utility on your PC provides your address to their server. The service is called DDNS. Some routers have this built in. Instead of an address like nnn.nnn.nnn.nnn, the address of your PC becomes something like g4dsp.homeip.net. The server finds you based on its knowledge of your actual address. I believe this is discussed in one of the sections of my website (www.telepostinc.com) under the heading Remote Base Station Related Stuff... I posted an email about this to the list in response to your earlier inquiry, but I forgot to change the Subject (it was posted from a digest entry), so you may have missed it. There is lots of interesting info about the remote control system I use there. 73, Larry N8LP > Date: Wed, 30 Jan 2008 07:55:13 +0000 > From: Stephen Prior <[hidden email]> > Subject: [Elecraft] Remoting the K2 > To: elecraft <[hidden email]> > Message-ID: <C3C5DDE1.20E5%[hidden email]> > Content-Type: text/plain; charset="US-ASCII" > > Thanks to all with their help and advice which I must now mull over.

You might want to look at dd-wrt. It is an alternative software for several types of home routers. I've run dd-wrt on the Linksys wrt-54gl and the Linksys wrt-350n (hardware version 1) and I'm happy with it. Recent versions of dd-wrt include DynDNS support (including several other dns services) as well as providing a lot of flexibility on forwarding specific inbound services (ports) to specific pcs on your home network, in case you have several.
Best of luck, tom n3ckk |

The only problem is that the location with the dynamic IP is the station in
which he's connecting from. And if he was to lock down the connection at the firewall to an IP he'd have to change that whenever he got a new dynamic address. It's a bad idea to tie a secure connection to a resolveable name. Those are much easier to spoof than an IP. But I guess its at least still better than leaving it wide open. Although I don't think most firewalls will allow you to put in a resolveable address. That would mean it would have to technically re-resolve it whenever each packet came in. Or after each DNS cache flush. -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Larry Phipps Sent: Wednesday, January 30, 2008 5:39 AM To: [hidden email] Subject: [Elecraft] Remoting the K2 Hi Stephen.

Larry (thanks for the email) and Brett
Thanks for your continued thoughts on this. I'm not sure, however, that I have made the situation clear enough. The computer (Mac) connected to the K2 is at home and is the one with the dynamic IP address. Does it matter what type of address the work network has? I'm working outside of my experience here, as you can probably tell! 73 Stephen G4SJP On 30/1/08 19:28, "Brett Howard" <[hidden email]> wrote: > The only problem is that the location with the dynamic IP is the station in > which he's connecting from.

A router with DDNS support can do this automatically. Plus, the firewall
is only open to a piece of hardware that converts serial port data into TCP port data... not to a PC. Nobody is going to hack into a black box with dedicated firmware when there are millions of Windows machines out there to hack into. There is very little risk in that, unless I'm missing something (not unheard of, BTW ;-) Larry N8LP Brett Howard wrote: > The only problem is that the location with the dynamic IP is the station in > which he's connecting from.
