WSAECONNRESET An existing connection was forcibly closed by the remote host.Explains the meaning of the "WSAECONNRESET An existing connection was forcibly closed by the remote host." error and demonstrates a way to reproduce it by setting the "No Transfer Timeout" setting on a FileZilla FTP server to a very small value.
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <body> <% set ftp = Server.CreateObject("Chilkat.Ftp2") ' Any string unlocks the component for the 1st 30-days. success = ftp.UnlockComponent("Anything for 30-day trial") If (success <> 1) Then Response.Write "<pre>" & Server.HTMLEncode(ftp.LastErrorText) & "</pre>" End If ftp.Hostname = "192.168.1.108" ftp.Username = "myLogin" ftp.Password = "myPassword" ' Connect and login to the FTP server. success = ftp.Connect() If (success <> 1) Then Response.Write "<pre>" & Server.HTMLEncode(ftp.LastErrorText) & "</pre>" End If ftp.Passive = 1 ' In this example, we've set the FileZilla FTP Server's ' "No Transfer Timeout" to 5 seconds.
