FTP Times out

Question

Hi folks,

I'm new to this method of communication, so pardon in faltering!:)

To make a long story short, if I use DTftp and build a client, I can connect to a local server and retrieve a file just fine. However, when I try it on a remote server, I can logon (see the result in the VisualStudio window), chdir (same thing - last return it 'cwd was successful' but, when I try to GET, or even DIR, it times out with a long-winded message about the host not responding in time.

I'd think it was a firewall issue, but I can retrieve the file from the same location from a command window using ye olde FTP.

Any ideas?

Many thanks in advance,
Kind Regards,
Ron

Ye olde FTP is probably using active (PORT) mode transfers.

Try changing to active mode (the default is passive, PASV)

:lol:

Sorry so long getting back - I was away yesterday and didn't pick up your reply until about nine o'clock last night.

Many thanks! I'd thought about active vs passive but, based on what I read on the internet thought 1) No one uses 'active' and 2) if they did, command line ftp wouldn't be smart enough to switch to it without being told.

Looks like I owe Microsoft an apology!

My FTP class now works a treat - thanks again! :)
