Since upgrading to new openssh-3.6_p1 I haven't been able to use KDE's sftp:// kioslave. Today I really needed that functionality back so I downgraded openssh to 3.5_p1-r1 and it all works all happily again. I think I traced it down to the way kde starts up the ssh process -- the parameters no longer work the same for newer openssh. It seems KDE starts ssh with parameters like -o ForwardX11 no And the openssh folks changed to to require an "=" character -- i.e. -o ForwardX11=no This is all very theoretical and uncertain -- just something I noticed based on the process list. I know ps lies sometimes so the failure can be due to a completely different reason. Reproducible: Always Steps to Reproduce: Actual Results: hangs with the "connecting to host" window Expected Results: a new konqueror window with the contents of the remote host

*** Bug 20620 has been marked as a duplicate of this bug. ***
This has been noted as a bug on the kde bugzilla. http://bugs.kde.org/show_bug.cgi?id=51359 We'll see where this goes..
The sftp ioslave code in KDE is not currently set up to be able to handle the change that have been made from openssh 3.5 to openssh 3.6. I plan to create a patch for KDE, but it will be binary incompatible and as such it won't be available in the 3.1 branch. I recommend staying with 3.5 for now. We are currently evaluating whether to require openssh 3.5 for kde 3.1, or to do some patching on the gentoo side.
Created attachment 11825 [details, diff] Fixes ssh breakage in 3.1.x
Scratch that, after some looking it looks like this may be an easier fix than I thought. I am attaching a patch against ksshprocess.cpp, which exists in the kdebase/kioslave/sftp/ directory. Can you try this patch out and see if it fixes your problem?
compiling now. will let you know in an hour or so. thanks!
there's a small error in the second hunk of the patch (missing + after tmp). fixed it here locally, but still compiling.
ok, just tried to use sftp with the new patch and now I get "Error encountered while talking to ssh." It doesn't hang, but it also doesn't ask for login/password anymore.
I don't have the kde source on this computer, so I can't run any more tests on the patch at the moment, but this is what you should see in the ps list after starting the sftp: /usr/bin/ssh -p 22 -o 'ForwardX11 no' -o 'ForwardAgent no' -e none -l caleb -v cvs.gentoo.org -s sftp Are you seeing something close to that?
Unfortunately I can't run ps fast enough before the command finishes, and I can't for the life of me figure out how to use kdebugdialog so that it actually does anything useful. Any hints would be greatly appreciated.
Okay, after further investigation I was above to make this work. Please revert my first patch. Instead, in ksshprocess.cpp line 101 "ssh-userauth2 successful:" change to: "Authentication succeeded" And try it. It now works for me using openssh 3.6. Upon your confirmation I'll make a patch for the gentoo ebuild.
Confirmed! Works all happily now with openssh 3.6.1_p1-r2. Thank you for your help.
caleb solved it, fix will be included in the next kde release (3.1.2)
