I don't know if this story is true or not, but I hope it is. A guy who is our sys admin said he read on a sys admin type mailing list that the crew of the International Space Station are having some computer problems just like a lot us down here on earth. It seems that the U.S. provided computers running AIX and Win NT. A Win NT computer is being used as an SMTP server. Apparently the crew are becoming experienced Win NT sys admins because they are having all kinds of problems with the SMTP server.
The Russians brought computers running Linux. They seem not to be having SMTP server problems. As I said, I heard this third hand and have no idea if its true or not. It was probably started by a bunch of Linux college geeks, I don't know. Someone from NASA will probably roast me alive...
