earlier today (or yesterday -_-) I've rented a VPS (from aruba cloud) for a personal project. I've managed to establish SSH connection in putty so I can run shell commands alright. What I want to do now is get access to my VPS's graphical interface. I've been trying to use X2go (from a computer running windows 10) and it returns error message:

ttyname failed: Inappropriate ioctl for device.

After googling this for a while I've found out that this means that some device has been called in a way that it can't interpret, but I can't figure out what device (networking card?) exactly is the source of this issue, much less how to resolve it. Does anybody know how to do that using terminal commands only?

  • Is there an X2Go server running on the target? – ridgy Sep 02 '16 at 11:45
  • Yes, there is. And so is ubuntu-desktop. – Verrierr Sep 02 '16 at 15:06
  • As you are able to log in via ssh/putty, open one terminal session and issue tail -f /var/log/syslog; leave the terminal open and try to open the X2Go session. Maybe syslog will show more information on errors. – ridgy Sep 02 '16 at 19:42

In your /home/user/.profile add the following line :

tty -s && mesg n

... and remove any other "mesg" line which is the root cause of the problem

    WHY is this working? what's different in comparison to mesg n || true which I had before? None of these commands seems to make any real difference, at least if I run them in my ssh session. – velis Mar 29 '18 at 17:07
  • This worked! I didn't expect it to work at all. I commented out mesg n || true, and added beneath it tty -s && mesg n as instructured, but it would be good to know what it did! Can you clarify? Do you know @xybal and @velis? – Fiddy Bux Dec 23 '18 at 21:37

    I should add, that I was having this problem with root account SSH key-pair access using X2GO, whereas my standard user account works fine without this modification. I edited /root/.profile, rather than my standard user .profile. Would really like to know what the change does though. Link? – Fiddy Bux Dec 23 '18 at 21:48
  • Is all that it does silences tty (print nothing, return exit status) and disallow messages in mesg? I got this info by simply man tty and man mesg. Both options are near the top of the manual pages. – Fiddy Bux Dec 23 '18 at 21:52
