Don't let anyone at all connect to your local Xastir instance through the interwebz. Put it behind a firewall, and expose your server port only to your LAN. If you are running a bi-directional igate (and these should be the only kind) then monitor what is going out of your RF interface as third-party or message traffic from APRS-IS. Shut down your transmit if it's abused. Can't think of any other way. APRS pass codes are completely insecure, and the algorithms have been public for well over a decade. Anyone can write one, and there's nothing to be done about it. That cat is long out of the bag. -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Made ya look! - Southwest Cyberport<http://www.swcp.com/~russo/> www.swcp.com Hey, what's a nice person like you doin' in a crummy joint like this?
