I'm having a problem that my provider is unable to explain. Let me demonstrate by an example: from 207.141.254.20: lynx www.sarc.msstate.edu The connection will be immediate, but it will be 2 minutes before any data is transferred back. telnet/ftp will send the prompt back immediately (we're only 7 hops apart afterall). from outside of 207.141.254.: lynx www.sarc.msstate.edu no slowness problem. from 207.141.254.20: ftp ftp.netbsd.org 10 seconds until the first prompt. from outside of 207.141.254.: ftp ftp.netbsd.org 3 seconds. See the pattern here? Note that this applies to all 207.141.254. machines. Can somebody tell me where to even start tracking down the problem? If it's a reverse DNS lookup problem, is there any utilities/commands that I can run to verify? My provider is handling my primary DNS, by the way. Thanks! Tim
