konqueror sftp:// URL handling broken with openssh >= 5.6 (open a bug?)

Tim, Robert, Serghei, All There is an error in konqueror sftp URL handling that causes sftp from konqueror to fail. I first reported this back in October 2010 on the various lists reporting that the konqueror url syntax 'sftp://user@host:port/path' no longer works after an update to one of the associated packages (probably openssh Back in October, sftp 'in konqueror' continued to work to boxes where ssh was on the standard port 22, but would fail if sftp had been moved to a high port. 'fish' continued to (and continues in Trinity to) work to both standard and non-standard ssh ports. Fast-forward to 'today' with Trinity svn. (1) sftp in konqueror fails to work at all: http://www.3111skyline.com/dl/dt/trinity/err/ssh/ss-err-enc-talk2ssh.jpg the sftp target host in the screenshot above (dcrgx2) has ssh on the standard port 22. Now konqueror will not talk to any host - on standard or high port. (2) fish continues to work just fine (both standard and high ports) http://www.3111skyline.com/dl/dt/trinity/err/ssh/ss-fish-OK.jpg (standard) http://www.3111skyline.com/dl/dt/trinity/err/ssh/ss-fish-OK-high-port.jpg (high) (3) sftp from the command line in Trinity (konsole) works fine to either high or standard ports: http://www.3111skyline.com/dl/dt/trinity/err/ssh/ss-sftp-cli-OK.jpg So the problem is definitely with konqueror's handling of the sftp URLs and how it passes that information to openssh. This is a distribution generic problem with KDE3 after the change to openssh (I'm pretty sure). In older releases of distros (like SuSE 11.0 - sftp in konqueror continues to work normally) The bottom line for Trinity going forward is that the normal konqueror sftp syntax of: sftp://user@host:port/dir1/dir2 is broken. This is confirmed as a konqueror problem because, in Trinity (and kde3 in general), the command line syntax: sftp -Pport user@host:/dir1/dir2 continues to work fine. So as does 'fish://'. I have researched this issue for a couple of months and the best I can tell is the problem is in kdebase/kioslave/sftp. There were references to an old Gentoo bug that fixed ksshprocess.cpp line 101 to regarding and openssh 3.6 problem with "ssh-userauth2 successful:", but I know that doesn't have anything to do with the current problem. It may be the same file that needs fixing now, but different problem. For Trinity, do we want to open up a bug report so this one can be tracked, or do we want to work it from the mailing list? Either way, the fix is probabl simple, but this is a biggie for sftp functionality. Thanks. -- David C. Rankin, J.D.,P.E.
