[SOLVED] SSH - x2go - Keep applications running after session close

I have managed to install and configure Open SSH on my NUC. Everything is working, i can start applications with GUI and everything. I start deluge and the application opens in on my desktop, but is running on my NUC. Sweet.
But, when i close either the terminal that iv'e used to connect to my nuc, all the application om the NUC (my remote computer) are being closed as well. That was not my intention. I want to fire up some applications, like deluge and ftp and some compiling jobs, then just close my session, but keep all the things running on the NUC so i just can shut down my main computer and have the NUC running all applications in my closet. Is there a way to configure that?

Use tmux for shell based stuff and vncserver if you need GUI stuff.

Well, i have just managed to learn the very basics of SSH. Don't actually know anything about it. So open ssh can't manage this?
And a little addition, i want to see the whole desktop, panel and all aswell. Now i'm just firing up applications via the shell. So as i stated in a previous post i'd like the Teamviewer functionality but headless. Unfortunately teamviewer doesn't support headless fully, otherwise i would have used that right away.

Sounds like you'd want vncserver *or* to use x2go/freenx

Ok, I'll try x2goserver/x2goclient again if i dare. But having a working SSH-connection, do i have to configure conf files for this application aswell or will it inherit/interfere with current Open SSH config?

Got an error setting up x2goserver. When creating db

x2godbadmin --createdb
DBI connect('dbname=/var/lib/x2go/x2go_sessions','',...) failed: unable to open database file at /usr/bin/x2godbadmin line 103.
backend=sqlite at /usr/bin/x2godbadmin line 103.

The Wiki doesn't state this error. Iv'e googled it and it ends up in bug reports.

Sorry. Wasn't sudo. Fixed.

There is also nohup, disown and screen.

I personally prefer disown as you can use it even when the process already started.

Re: [SOLVED] SSH - x2go - Keep applications running after session close

Thank you all.
I have sucessfully managet to set up x2go on both computers. Exactly as i wanted it.
But, can i safley "suspend" my remote session from my desktop and turn my computer off and my server/NUC keeps running the applications? Want to know this in particular, before detatching it from my monitor and "hide" it some where.

Edit: I get "Enter passphrase to enkrypt a key" error message. Trying to follow this:

ssh-keygen -t rsa
This will create following files inside your $HOME/.ssh/ directory:

~/.ssh/id_{rsa,dsa}
~/.ssh/id_{rsa,dsa}.pub
You'll need to transfer the public part of the key to the wanted server. You can do this using the ssh-copy-id command:

$ ssh-copy-id -i ~/.ssh/id_rsa.pub user@remote-system

Except the "ssh-copy-id" tried to add my custom port as well but no luck.

I cant use my local desktop. If i choose Xfce-session it works just fine everything.
Have checked on the net about a solution. Found a thread here at this forum that it might be a bug.
https://bbs.archlinux.org/viewtopic.php?id=189061

So. Is there another application that can manage to do this? Connect to my local desktop, as x2go is supposed to do?

Or is it impossible from arch > arch? There are a lot of people succeeding to other Linux distros and even Windows with this application, but if it's buggy i'd like to use another (bug free) one if there is one out there.

Re: [SOLVED] SSH - x2go - Keep applications running after session close

My remote server/NUC

Installed x2godesktopsharing from AUR via yaourt
Added my user to x2godesktopshare group.

sudo gpasswd user x2godesktopshare

Edited /bin/x2golistdesktops and changed:

ss -lxu

to

ss -lx

Rebooted

After reboot, checked that the services "sshd.service" and "x2goserver.service" was started (I enabled these before and they start @ boot or login)

Client

Runned x2goclient, choose "Local Desktop"

Voila. It worked. Case closed
