[dba-Tech] FTP

[Stuart McLachlan]

Ah, PureFTPd. A search on
 Pure-FTPd   "I won't open a connection to I won't open a connection to" FTP.exe
tgives a number of hits which all say roughly the same thing.

Here's one such:

The Windows FTP command-line client (ftp.exe) does not support the passive 
mode, on any version of Windows. It makes it pretty useless nowadays due to 
ubiquitous firewalls and NATs.
Using the quote pasv won't help. It switches only the server to the passive mode, 
but not the client.

Use any thirdparty Windows FTP command-line client instead. Most other support 
the passive mode.
For example WinSCP defaults to the passive mode and there's a guide available for 
converting Windows FTP script to WinSCP script. If you are starting from the 
scratch, see the guide to automating file transfers to FTP using WinSCP. Also, 
WinSCP GUI can generate a script template for you.
