Slow ftp/telnet/xxx seems to be one of the most frequently asked questions on any Unix related group I've seen and it all boils down to three letters DNS. The far side agents try to authenticate the name by looking up from the IP they get. If there is no reverse mapping - it can take well over a minute to search all their namesevers for a possible match - then it will 1) let you login or 2) reject you completely - and a great many sites will reject you if you can be authenticated. You can control the DNS for your machines. Make sure everthing is correct AND that whereever you get service from is properly reversing your names. If not change providers - like I had to. -- Bill Vermillion - bv @ wjv . com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
