The many FTP download/upload errors and connection issues are caused by brief network outages or incorrect routing of FTP traffic. These types of issues are difficult to reproduce, diagnose, and troubleshoot. However, due to the large increase in network security, some FTP errors may be resolved by changing your FTP settings. Depending on your FTP client, any firewalls or routers your machine is behind, and anti-virus software that you run on your machine, you may encounter errors when connecting to your FTP server or using FTP commands. You need to adjust the Firewall or contact your ISP in this case. While there are many custom errors that your FTP client may return, if you receive any of the errors below, or if your connection simply times out when you use the "ls", "put" or "get" get commands, you may need to adjust your Passive mode setting:
425 Can't build data connection: Connection timed out
425 Can't open data connection
426 Connection closed; transfer aborted
503 No port command Issued first
In most cases, these errors indicate that you need to set Passive mode to ON. However, depending on your network
connection, firewall, or router, you may actually need to disable Passive mode. Also,451 error messages do occur some times due to local settings. It usually occurs if you use ftp via browser. Usualy Broken pipe error. try some FTP client in that case.
For Windows command-line FTP, you will need to enter "quote PASV" at the "FTP> prompt" (once you are connected to the server) before you begin performing any directory listings or file transfer operations (ie: ftp> quote PASV). The "quote" argument is the same as the "literal" argument, and uses the same syntax.
Please note: depending on your own network settings, this option may not work.
