FTP - Single Connection

Is it possible to make DOPus use a single connection while working with a given FTP? There's one that I need to upload files into, but it only allows one connection. It seems that when DOPus initiates the upload, it tries to establish a second connection, which fails, of course. Thanks.

There isn't a setting, but Opus should only create additional connections if it needs them.

For example, if you are uploading on the main connection and change directories in the lister then Opus will attempt to create another connection to get the directory listing, but if you wait until the download has finished then Opus should re-use the existing connection.

If that isn't happening, check the FTP log until Tools -> Output Window. There may be an indication there as to why the first connection is no longer being used and a new connection is being attempted.

Thanks for the reply. This is what it says...

The last thing tried was uploading a file. So, I assumed that is what caused the second connection attempt there...

I can't see anything obviously wrong there. You'll have to report it to GPSoftware if you want them to look into why the second connection is being established.

It's worth trying the same thing with another FTP client to rule out the possibility that the server is closing the connection.

Thanks. It works with CuteFTP as long as I don't have it trying to do anything in DOPus at the time.
