Incompatible with ncftp? about server

[lunny]

I haven't tested ncftp, I have tested Transmit & chrome browser on macOS, both are work. You can visit http://github.com/goftp/ftpd to find the example

Hmm ok. I also tried OSX's "native" command line ftp utility and could not make that work at all either. I'm trying to build a kind of an in-memory Driver which would later on perhaps later actually do something with the data, but for now I'm just trying to figure out how to make things work with (any) FTP client.

Any idea why the passive mode setup doesnt seem to work?

[matti777]

Also, could you please perhaps test it with NcFTP which has been the de facto FTP client cli for over a decade?

[matti777]

And when I try to do the same with the OSX's 'native' ftp cli, the following happens (im logging in and trying to do ls / dir):

[matti@babylon tmp] 09:37:27 % ftp localhost 8021
Trying ::1...
Connected to localhost.
220 Welcome msg

331 User name ok, password required

230 Password ok, continue

Using binary mode to transfer files.
ftp> ls
211 END
Passive mode address scan failure. Shouldn't happen!
ftp> dir
257 "/" is the current directory
parse error!
ftp> 

And the server output is:

It seems command EPSV is failed and LPSV is not supported.

[matti777]

To me it appears your implementation for PASV mode is broken; I could not get this to work with any of the 4 clients I tried.

I did get the PORT mode to work on one, though. This however is not suitable to my needs.
