Asp.Net Problem

Hello

I am trying to use the edtftpnet-1.2.2.dll with C#. When I run the Login() method in a Desktop application everything works properly, but the same code, with the same Server, Password, Port and User, in an Asp.Net Application, always says that the host didn't respond. Am I missing any configuration? It seems to me that some permission under IIS is blocking me.

Thanks in advance for your help.

OK, Here is the log after setting AutoPasiveIPSubstitution = true;

The IP addresses are the same which is a good start.

It is possible that there is a firewall problem preventing you connecting to the host on that port. If you have access to the server logs, it would be helpful to inspect them.

The strange thing about this server is that in non-secure mode, PASV returns the same IP as the resolved hostname. But in secure mode, it is different. If you are able to talk to the people running the server that might help - there could be a configuration problem.

And do you have any clue why I can't access the FTP through and Web Application?

As I told you, the message I receive is:

"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"

I couldn't use this log issue either, probably because it is not available in the version I am using (1.2.2)

Have a look at the help to see how to enable logging - or the sample code.

Hello

I learned how to enable loggin in edtftpnet 1.2.2, and here is my problem:

This first log is the one I got when I run my code in a Windows Application - the one which creates a .exe file.

It looks like you have no network connectivity to 200.152.8.58. The problem must be broader than just edtFTPnet since the failure occurs before any actual FTP protocol communication takes place. So if you were to try to simply open a plain socket connection to port 20 on 200.152.8.58, you should find that that also fails. I don't know why you have having network connectivity problems.

Sorry I couldn't be of more help.
