Socket.Receive() Failed

Question

Been running edtFTPnet/Pro in a test environment for about 2 weeks now. Everything is smooth.

We are connecting to a 3rd party's test environment which has a different IP, username, and password than the production environment.

I started testing the connection to their production environment and am unable to connect.

- Filezilla works.- edtFTPnet/Pro gives an error... see the code section for logging

The logging/testing was done with the FTP shell program though my .NET program gives the same IO error. Anything with *PROTECTED* is just me preventing company-specific information.

Any help on this would be greatly appreciated!

Thank you,

Answer 1

You're connecting to the SSH port, 22, instead of the FTP port, 21, using the FTPSExplicit protocol. That won't work.

You need to set the protocol to FTPSExplicit and connect to port 21 (if you want FTPS), or set it to SFTP and connect to port 22 (if you want SFTP).

Answer 2

That was it. Thanks for the help! I had to set transfer type to SSH.

The debugging I posted was actually for the edtFTP shell, not my .NET code which threw the same error. Is there any way to set the edtFTP shell to work with explicit SSH?

Again, thanks for the help.

Answer 3

Yes:

set protocol = sftp

Answer 4

Perfect! Once again, thanks for the help on this.
