I am working on the Difax issue. I am trying to get an indication on what I need to do to get our FTP server to act as an LDM server for feeding Difax data. It appears I am firewalled off on port 388 and I'm pursuing this with the networking people at Unisys. I have two methods. First the FTP server does get all the Difax charts in a compressed PCX format from our primary feed. Second, I'm downloading charts from the NWS FTP site. Right now, I'm providing this data is both PCX and PNG formats. I'm going to stay away from GIF for obvious legal reasons (even us at Unisys stay away from GIF). Either of these sources could be pqinserted into the IDD from our end if we resolve firewall issues. There could be a small issue with bandwidth. It appears Alden feeds Difax to a number of customers directly. It is unlikely we can feed more than a couple of sites given bandwidth concerns. We might forward the data to a single controlled LDM which can then go to the various Unidata sites. Of course, this might be a moot issue if the T3 gets installed here. Once I have this tested, I need to talk to Mike Porreca and Ron Guy on how we might work with Unidata on this issue. ________________________________________________________ Daniel Vietor Mail: devo@xxxxxxxxxxxxx Unisys Corp Title: Engineer/Meteorologist 221 Gale Lane Phone: 610-444-2407 Kennett Square PA 19348 Fax: 610-444-2420
