[arch-general] Thunar sftp connection not working - access denied
Hi Folks,
since some time I cannot get thunar connect my remote servers folders via sftp.
Error dialog: Failed to open "/my/remote/path on my.server" access denied
ssh access works as expected.
I feel like it stopped working after I got this arch announce: https://www.archlinux.org/news/d-bus-now-launches-user-buses/
System: recent arch x86_64 xfce4 4.12
I didn't find anything useful by net search, so my question here:
Did anyone else get hit by this? Is there likely a relation to changes in D-Bus.
Any hint to nail down this one appreciated.

So, does sftp work from the command line?

As a workaround, you can use sshfs. sshfs will mount a remote filesystem over ssh.
I use sshfs quite a bit with Thunar. Thunar lists the mount as an external drive.

I know about this but well, it used to work and has stopped doing so, now.
digging a bit deeper.. It apears to be a problem of ssh-key authentification.

Considering that CLI sftp and Filezilla work, this is probably a GVFS related issue.
The part of the log output that sticks out like a sore thumb are the lines that look like this:
Oct 13 19:36:08 my_machine gvfsd[758]: ### SFTP: handle_login #1, initial_connection = 1 - user: me, host: strict.remote.host, port: -1
"port: -1" just doesn't seem right. At best this means "use the default port". But you would think that if it uses the default port, then the log would say "port: 22".
At worst, this means literally "use port -1", which means that -1 could overflow in unsigned integer arithmetic so it is actually a really high port.
Have you tried running the ssh commands yourself?

New facts but no solution..
After dbus update I restarted dbus by hand: Restarting dbus as root yields: ========= [root@myhost ~]# systemctl restart dbus PolicyKit daemon disconnected from the bus. We are no longer a registered authentication agent. =========
After new Loggin in XFCE - tataaa sftp-connection is established without issues. Cannot shutdown machine out of xfce session and have other quirks but this one works.
After machine restart old behaviour is back.
This tells me something's wrong with PolicyKit settings?
Forgot to mention: ssh-agent running (started by keychain)

most likely this isn't a problem, as successful actions also have this values.

Dbus is tied into almost everything nowadays. Restarting it can do all sorts of interesting things.
After new Loggin in XFCE - tataaa sftp-connection is established without issues. Cannot shutdown machine out of xfce session and have other quirks but this one works.
After machine restart old behaviour is back.
This tells me something's wrong with PolicyKit settings?
So, if PolicyKit is not registered as an authentication agent, gvfs SFTP works. I'm guessing it is falling back to some other authentication agent.
Forgot to mention: ssh-agent running (started by keychain)
Maybe ssh-agent is the fallback.

I would have to look up those ssh options. They could very well create a tunnel.
In your log file:
Oct 30 00:22:22 my_machine gvfsd[1047]: ** (process:1315): WARNING **: Failed to setup SSH evironment: The name org.gnome.keyring was not provided by any .service files (g-dbus-error-quark, 2)
Is gnome-keyring installed? It looks like gvfs (being a GNOME application) is trying to start GNOME keyring.
I switched pretty much everything to gpg-agent. In .xinitrc I have this:
# Start the GnuPG agent and enable OpenSSH agent emulation gnupginf="${HOME}/.gpg-agent-info" if pgrep -x -u "${USER}" gpg-agent >/dev/null 2>&1; then eval `cat $gnupginf` eval `cut -d= -f1 $gnupginf | xargs echo export` export SSH_AUTH_SOCK="${HOME}/.gnupg/S.gpg-agent.ssh" else eval `gpg-agent -s --enable-ssh-support --daemon --write-env-file "$gnupginf"` fi
It uses some old options that I should probably clean up, but it still starts and works. But you will need to kill it with 'pkill gpg-agent' before logging out.
I only use gnome-keyring-daemon on my laptop for keeping track of Wifi passwords in NetworkManager.
Feel free to look at my configuration at
https://github.com/KlipperKyle/dotfiles/blob/master/xautorun
(.xautorun is sourced by .xinitrc. Then .xinitrc calls my window manager.)
If I get the chance, I might try to remove gnome-keyring-daemon and see what happens if I use gvfs.

It definitly is :o))
https://bugs.archlinux.org/task/46398

No, don't use it..
ssh-agent is running fine - gvfsd doesn't get the environment and thus can't see this.

So workaround is in place an one more vote set for the mentioned bug.
Thanks for Your help.
