HS/FS - √ - FTP connection

[Warichet]

Hi,

I'm unable to transfer a file via FTP.
So far, in Projekt/FTP, I've setup a FTP server.
This seems OK as I can connect to the server from a browser.

As an exercise, I'm trying to transfer the debug page, but I'm unsure about the options to select.
In the Visu, I've setup a button, with Befehle "Debug per FTP ablegen"

My mistake is probably in the path/filename, but don't know how to write it.

Thank you for your help

Please try "/debug.html"

Hi Matthias,

Please try "/debug.html"

I've already tryed several alternatives, included "/debug.html". No go
Most of the time, my problems stem from the fact that I don't understand the implications of the options, i.e.

Pfad
Pfad/Dateiname

Is it supposed to work to export the debug on a FTP server ?
Maybe there is another setting about FTP ?

Still no joy with the FTP.

By looking at the log file of the FTP server (NAS QNAP) I see several instances of "Login Failed"

I'm pretty sure that the username and password are correct ( a test with a browser works fine).
I unchecked the box "Passiv modus" and now the login works, but still no file transfer.

The "Pfad/Dateiname" is that the source or the destination ?

Thanks


PS: I thought "Passiv modus" was for file transfer, not for login ?!?

Yes, generally that's correct for FTP. The two modes "Port mode" and "Passive mode" only relate to the data connections. Each data transfer is handled by a separate data connection where in normal stream type connections the data transferred between TCP-open and TCP-close makes up the datafile. In passive mode the data connection is opened from the ftp client to the ftp server which answeres the destination port on the PASV command from the client. In port mode the ftp client announces the port to the ftp server which then opens the data connection back to the ftp client from source port 20.
So while for login only the control connection on server port 21 is relevant, even a listing of the filesystem needs a data connection. On the other hand I have seen problems on control connections where the banner is multiple lines which may be in conflict with ancient firewall software. Or EOL is not exactly handled like the standard implies. There may be other strange problems.

Thank you for this detailed explanation, much appreciated
I thought setting up a FTP connection was trivial

Now that I see in the server log, that the ftp login is accepted, there must be something wrong in my definitions on the HS.

Any idea ?

Someone has a NAS QNAP and a FTP connection to the HS ?

Hi Warichet,

Yes, I have also HS and QNAP.

If login is correct. The next step to check would be: the correct path (directories should exists) and access right of the ftp user to write to the QNAP.

If the path is wrong this leads to an error.

If the the ftp user has no write access leads also to an error.

Hi Tbi,

Yes, I have also HS and QNAP.

We are 2 to be alone

The next step to check would be: the correct path (directories should exists)

Yes, I suspect this to be wrong. I tried several combinations with and without leading "\" but I don't know where the root of FTP starts.
Do you have a working example, please ?

and access right of the ftp user to write to the QNAP.

I didn't create a specific FTP user, as I'm alone, I'm using admin all over. I hope this is OK ?
When using IE8, with the syntax ftp://<NAS IP> username password, it works fine.

Thank you for your help.

Hi,

it seems it needs an absolute path like /Homeserver/Debug/debug.html

This is the path on the QNAP.

At QNAP / is root and then a direktory "Homeserver" exists.

Hi Tobias,

... and 36 reboots later, I read your reply, with the same conclusion

it seems it needs an absolute path like /Homeserver/Debug/debug.html

On the QNAP, I had already a directory Ftp, and thought that was the root
I've created /Ftp/HS and then I could save my debug.html
I wonder why my first test "/debug.html" didn't work, probably it's not allowed to write in the root.

BTW, this thing is case sensitive

Thank you

[tbi]

Fine!

I remember a sentence from university:

... and the rest is very simple, you can only make mistakes.

But they happens

And, yes QNAP is Linux and this is case sensitive, sure.

btw, any idea about which distribution it is ?

I installed eibd on it and want to read more about the available commands.

Thanks again
