Can't connect with FileZilla about ftpserver

I have the same issue. For now I'm just using the plain FTP protocol this is not ideal for long term but for now it works.

FYI, the first part of your issue should be fixed now that pull request #51 has been merged

Related: dotnet/corefx#8811
EDIT: Possible workaround: https://www.nuget.org/packages/GnuSslStream/

Version 3.0-beta.1 is released which should fix your first issue (AUTH TLS with server without certificate).

Thanks, I'll give it a try. For the SslStream issue, is calling the ShutdownAsync() API not possible as a workaround?

For the second issue, here's a gist of a connection log from ftptest.net to my server. It seems that the "unroutable address in passive reply" issue is something ftptest.net chokes on, while FileZilla proceeds by reusing the known server address.

Reply: 227 Entering Passive Mode (10,0,0,4,195,127).

Is the local IP being returned here a bug, or some misconfiguration with my server? Or is it expected, and ftptest.net is just not falling back properly?

The FTP server doesn't know its public IP address when you're using NAT. I'll open a new issue for this feature.

[avonheimburg]

No need. I added a FTP server parameter "PasvAddress" my pull request #50, which you already merged. It is the exact setting you are looking for.

@ArrowCase : There is no such thing as ShutdownAsync in SslStream for net461/netstandard2.0. There isn't even an Close method for netstandard1.3.

[ArrowCase]

@fubar-coder That's an annoying omission from netstandard20. Apparently the changes were done in time for its release but weren't considered in-scope.

I can confirm that @avonheimburg's changes fix both the initial TLS connection problem and the passive address behind NAT/firewall issue. Do you want to keep using this issue for the SslStream stuff, or close it and I can make another one focused on that?

[fubar-coder]

I can reopen issue #49 and close this one.

Hello, how do I set that pasvAddress. I'm trying to mount an custom implementation of FTPServer using your nuget on a Docker server but I'm facing a lot of problems. One of them is that I want to set this passive address to public endpoint. How can I do this? Thanks

I'm trying to:
services.Configure(opt => new SimplePasvOptions()
{
PasvMinPort = 12000,
PasvMaxPort = 12020,
PublicAddress = System.Net.IPAddress.Parse("###publicaddress###")
});

Doesn't work...
