Description Tamas Baka 2009-07-16 10:18:47 UTC

Version:            (using KDE 4.2.96)
Installed from:    Ubuntu Packages

I edit a lot of files in kate and copy files to ftp and sftp servers in dolphin.
The password dialog pops up a lot of times, sometimes I don't even see them. Very annoying by the way :-P

Sometimes (1 or 2 times a day) something goes wrong and the connection fails. After this I can't connect to the same server no matter what I try. Connection fails both in dolphin and kate. The password dialog doesn't pop up and at the bottom of the panel in dolphin I get a reddish background with a close button. I can connect to other servers without problem...

This didn't happen in KDE 4.2.4

Oh, I forgot:

I have to log out of KDE and log back in to make it work again...

I am seeing exactly the same thing on KDE 4.2.98 (Suse Factory build). I see two problems:

* KIO_SFTP uses the wrong username to login on the server
* Dolphin launches multiple login dialogs.

About problem 1:

I can see in the server logs that KIO_SFTP tries to login using only *part* of the username provided by the user. When I enter an SFTP URL in Dolphin containing the username "user", I see in the server logs that KIO_SFTP tries to login using any one username of "user", "use", "us" or "u". After working with Dolphin for a while, the SFTP server blacklists my KDE workstation due to the repeated failed login attempts. Looks like something is going wrong with the username memory buffer in either KIO or Dolphin...

About problem 2:

It seems like multiple components of Dolphin (main file list, treeview sidebar, ...) launch their own SFTP connection, each of which generating a login dialog.


I don't know which of the above problems is due to KIO_SFTP and which it due to Dolphin.

Comment 3 Pascal d'Hermilly 2009-08-17 12:05:40 UTC

I confirm both problems in KDE 4.3  in Kubuntu Karmic (testing)

Comment 4 Andreas Schneider 2009-09-08 17:28:11 UTC

Dik: Could you please test this again with latest openSUSE Factory or KDE 4.3 from the Build Service?

kio_sftp has been rewritten for KDE 4.4. It has been backported for openSUSE.
