I wasn't aware of this problem. CVSup just calls gethostbyname() to do lookup, so it's no different from other applications in this regard. But I've seen these kinds of bogus "unknown host" errors on quite a few applications, even on a 56 K link. It may be gethostbyname() that's not trying hard enough. Anyway, I will try to fix it in CVSup, by making it retry a few times before giving up. Thanks for reporting this. -- John Polstra jdp@polstra.com John D. Polstra & Co., Inc.
