Downloading files form server

[MartinImrisek]

Hi everyone,

i have two simple questions about FileZilla server.

why if I
cd /path/to/my/file/
get fileName

is all working well, but if I want to download file directly with command
get /path/to/my/file/fileName .
I get this error "426 Connection closed; transfer aborted."

and second question:
if I want to use passive mode
cd /path/to/my/file/
passive
Passive mode on.
get fileName

i get this message "227 Entering Passive Mode (147,175,18,67,220,222)" and the connection time out.

Thank you for your answer.
Martin

What's the complete log from the server in all three cases?

[MartinImrisek]

The case: I cant download file from parent directory (the same case like from / directory)

What is the used client?

1st potential issue: The client uses Active mode (PORT). Active mode requires extensive client and client network/router configuration. Data ports are at the client side, for Active. Consider using Passive.

2nd issue: It's the client aborting the connection, it sends ABOR immediately.

[MartinImrisek]

1nd: Im using standard ftp service implemented in Ubuntu or java org.apache.commons.net.ftp.FTPClient. but with the same result.
There two aproaches work with many servers aroud Europe, so i dont think that I am doing something wrong, it has to be on server side, maintained by my coleague.

and thats it. no more log for user defor.

2nd: I dont get it, Client is aborting or server? I give no command for abort.

If the server receives an ABOR command despite the client not having sent that command, there can be only one explanation: A malicious firewall or NAT router is injecting fake commands.

[MartinImrisek]

A malicious firewall or NAT router is injecting fake commands.

If this is true, thats ridiculous.

And what is the matter with downloading? Why can't I download files from root directory?

Sad would be more appropriate. The kind of sadness that makes you realize all hope in humanity is lost.

And what is the matter with downloading? Why can't I download files from root directory?

Same broken firewall or NAT router.

[MartinImrisek]

thank you very much for your time, and I hope you are not joking with me

Same broken firewall or NAT router.
