Description gree 2010-03-11 21:48:10 UTC
Version:            (using KDE 4.3.5)
OS:                Linux
Installed from:    Ubuntu Packages

In KDE applications, FTP connections try to use HTTP proxy even if a FTP proxy is not set.

I use Settings -> Network settings -> Proxy -> Manual proxy configuration, where I have only filled HTTP and HTTPS fields (FTP field is empty). In our network there is only a HTTP proxy (no FTP proxy). If I use lftp I can connect outer FTPs fine, but if I try to use KDE FTP (presumably KIO FTP - tested Dolphin, Konqueror, Krusader) the connection hangs and ends after some timeout without any activity.

I've studied sent packets with wireshark and really even only with HTTP proxy on, the FTP connection tries to use our HTTP proxy server. If I turn off the HTTP proxy in the settings, the FTP connection works fine (surely web stops working as the HTTP proxy is turned off).

(Changing of PASV setting also have not helped.)

I can confirm this bug on my computer:

When we manually set http proxy and leave ftp proxy blank, we want proxy only for http. Ftp should go without proxy.

while kio ftp uses the proxy settings and it is impossible to access ftp with http proxy server.
