I've used snippets of this code for a speedy little internal file server for a while (albeit the reverse direction of the example). We just installed a fresh RedHat 8.0/perl5.8.0/dual athlon box, and for some reason, the client always corrupts the file. The file is always 50% larger than the original. It also seems the garbage appears in the same offsets in the file, but the garbage is different each time. Any idea why such simple code broke? joel@acdstar.com
