Dear All,
first of all: great software, we (a small educational organisation for trade union members) have been working with it
for years.
TL;DR: shared folders do not work, when I use the GUI to mount a share
directory ~/media/disk/SHARE-NAME remains empty.
Our Setup:
* x2goserver on a computer behind a rounter with portforwarding and dyndns
* x2goclient on a computer behind another router
* both debian stable
The connection from x2goclient to x2goserver works (I mean: I get my remote desktop and work there), but when I want to
use/mount a shared folder, nothing happens. I mean: If I want to access a folder on the x2goclient via the x2go function
“shared folders” from the x2goserver, the directory ~/media/disk/SHARE-NAME remains empty.
When I trigger the release in the GUI of x2goclient, the logs say:
on x2goclient

-----------
I then tried to reach the client from the x2goserver via SSH through the SSH
tunnel that was set up:
-----------
serveruser@x2goserver:~$ ssh [email protected] -p 53200 -i
/home/serveruser/.x2go/ssh/key.cicFLi
Warning: Identity file /home/serveruser/.x2go/ssh/key.WEIIYY not accessible: No
such file or directory.
[email protected]'s password:
-----------
This generates a message in the x2goclient log -- so the tunnel back to the client has been set up, but the temporary
SSH key is no longer available. A login with the password of clientuser is not possible.
x2go's sshd on x2goclient is running:
-----------
clientuser@x2goclient:~$ px aux | grep sshd
clientuser 237626 0.0 0.0 15680 9496 pts/6 S+ Nov05 0:00 sshd: /usr/sbin/sshd -f
/home/clientuser/.x2go/etc/sshd_config -h /home/clientuser/.x2go/etc/ssh_host_rsa_key -D -p 7022 [listener] 0 of 10-100
startups
-----------
The specific sshd_config looks like this:
-----------
StrictModes no
UsePrivilegeSeparation no
PidFile "/home/clientuser/.x2go/var/sshd.pid"
AuthorizedKeysFile "/home/clientuser/.x2go/.ssh/authorized_keys"
Subsystem sftp /usr/lib/openssh/sftp-server
-----------
Any idea what I could try next?
