Description Manuel Schmid 2010-02-24 18:16:56 UTC

Version:            (using KDE 4.4.0)
OS:                Linux
Installed from:    Ubuntu Packages

I am not really sure if this should be treated as a bug or a wishlist item. My problem is the following:

When I try to connect to my Webfaction webspace using sftp:// in Dolphin, I get asked for the password several times. Then, when I am lucky, I can browse the webspace normally. However, most of the times, I lose the connection soon and I am not able to connect anymore for quite some time, both with Dolphin and via the console. Webfaction pointed out that they only allow 30 simultaneous ssh connections, so I believe that the problem is related to this.

I don’t really know what is the solution to this problem, but I reported it anyway because it makes sftp:// in Dolphin useless for me and other users might be affected as well. Thanks for looking into this.

Same for me over ftp.
Disabling preview or use a non-icon view halps a little but still, when the cursor is over an element, a connection is open in order to fill the 'Information' panel, wich is annoying if connection limit for IP is 8 as with my provider. (as shown by "lsof -i | grep kio_ftp")

Maybe an option to choose when show previws could help.
Nautilus default, p.es, is to show previews for local filesystems only but also an option Always show is provided.

KUrlNavigator: Don't use KIO::stat() for all non-local URLs

Doing a text-resolving with KIO::stat() for all non-local
URLs leads to problems for protocols where a limit is given for
the number of parallel connections.
