While kdessh has been part of the KDE Software Collection since many releases, in the port to the KDE 4 Platform it has been broken and stayed so until now (if connecting to systems with only the KDE 4 platform). But obviously nobody has used it, because noone has ever reported this. Or have you just been lazy? 🙂
As kdessh hasn’t had a dedicated maintainer for many years and just gets the random maintainance usual to code in KDE’s software repository, it is now close to being kicked out of the module kdeutils to tags/unmaintained/4, before the final SC 4.4 release. Perhaps it can be fixed in time but it needs someone interested in it to do so.
So if you have been using it and would be missing it: get in contact!
Update: For this just bypassing this blog and have no clue what kdessh is for, here a short description from kdessh’s original author when asked about it some time ago:
kdessh is the remote equivalent of kdesu. It allows you to run a KDE
application on a remote host, potentially under a different UID,
without hassle. It takes care of things like setting up X cookies, ICE
cookies, DCOP (is that still used?) and $DISPLAY.
I am not sure how much this is used. It has limited use for a single
desktop use case but could be useful in bigger organisations where
you’d like to run applications remotely.
So these days with ssh doing X11forwarding and with ssh-agents/-add the purpose of kdessh can be questioned. But a proper integration with the KDE platform (e.g. KWallet) is still to be done.
