Something like this command "gksu -u root 'sshfs user@74.54.61.250:. ./mnt/point -o allow_other'" normally asks in a GTK dialog ( screenshot: http://www.webslot.be/img/openSshPopup.png ) for the ssh password. On Gentoo however this dialog doesn't popup, instead the password request appears in the terminal. Reproducible: Always Actual Results: The password request appears in the terminal. Expected Results: A GTK dialog asking for the ssh password. I can't figure out if this is a matter of USE flags, configuration, a bug, or a combination of that.
it looks like you don't have a x11-sshaskpass program installed.
(In reply to comment #1) > it looks like you don't have a x11-sshaskpass program installed. > Yes that's what i though. But neither emerging net-misc/ssh-askpass-fullscreen nor net-misc/x11-ssh-askpass helps, and net-misc/gtk2-ssh-askpass somehow got removed from portage. There doesn't seem to be any good information available about how to get such askpass app to work, or about why net-misc/gtk2-ssh-askpass is not available in Portage.
You need to make sure a few variables, notably DISPLAY and SSH_AKSPASS (or whatever it is again), stay set in your gksu environment. Please note that other distros might also configure gksu to in fact call sudo which you can configure /etc/sudoers (via visudo).
