My setup is weird and I can't change
it now. I have two machines:
local-machine:
it's my desktop running Ubuntu with Gnome
remote-machine:
it's one virtual machine, also running Ubuntu but without X
In both machines I have my private and public SSH keys.
I need to run SSH from remote-machine to local-machine and run gedit (in local-machine, under the default $DISPLAY) but openning a file in remote-machine throught SFTP. Something like this:
myuser@remote-machine:~$ ssh local-machine "DISPLAY=:0.0 gedit sftp://remote-machine/some/file"
The command above doesn't
work. gedit shows this message:
Could not open the file sftp://remote-machine/some/file.
gedit cannot handle sftp: locations.
Note that:
/some/file exists on remote-machine.
I can SSH normally from remote-machine to local-machine using my SSH key without any problems!
I can run the command DISPLAY=:0.0 gedit sftp://remote-machine/some/file in a terminal on local-machine and gedit opens the file on remote-machine without any problems - but the terminal in which I executed the command is running in DISPLAY :0 (really,
it's gnome-terminal).
I also tried -t option of SSH client (to force pseudo-tty allocation) but
it didn't
work.
If I try to run DISPLAY=:0.0 gedit sftp://remote-machine/some/file in local-machine but under a tty (for example in tty1, by pressing <Ctrl>+<Alt>+<F1>)
it doesn't not
work - I get the same error when running from remote-machine.
I found that if I pass the environment variable DBUS_SESSION_BUS_ADDRESS with a correct value,
it works! So, if I do something like that:
myuser@local-machine:~$ env | grep DBUS_SESSION_BUS_ADDRESS > env.txt
myuser@local-machine:~$ scp env.txt remote-machine:
and then:
myuser@remote-machine:~$ ssh local-machine "DISPLAY=:0.0 $(cat env.txt) gedit sftp://remote-machine/some/file"
it works! The problem is that I'm not on local-machine so I can't get the correct value for this env variable. Is there any other way to make this work?
