Please remember that spaces go after sentences. If you skip the spaces, it is crazy hard to read but more importantly the editor detects what you have written as a single sentence full of URLs. I manually edit every post that you make to make it readable. Just look at what you have written after you post or in the window to the right that shows what you are writing. If it looks like one long string or lots of bits get highlighted, that's because you are missing the spaces.

When i do the same in SSH(putty) to run the same command it shows it cannot be runned. It shows me the error like the screesnshot I have given!

Did you even read the error? It says very clearly that the service is already running, probably from when you ran it successfully the first time. What's the issue?

I try to take the system in remote by VNC viewer.I have taken 5 times the same machine in remote.When I take the system in remote by this VNC i shows me the error as "Cannot connect the host computer".So I try to restart manually the vino service in the concerned path I mentioned.I can run the command only in the terminal of the machine which I try to take remote.I need to restart the vino service by the SSH(putty).How to do that?

Please uses spaces after sentences.

This has nothing to do with SSH. I'm confused here. The service is running. If it doesn't work you need to troubleshoot why it is not working because it is running. You are asking why it is not running, but it is. So you are stuck on something that is not the problem.

Lakshmana

Ok.
I used to run the service in the putty for the purpose of enabling the vino service

scottalanmiller

Use this command to see if the service is listening properly...

netstat -tulpn

But it is already running. Why are you trying to run it again? We are going around in circles. There is no issue with SSH here.

scottalanmiller

Also, I imagine that you do not want this to run manually. You need to actually set up Vino to run as a dæmon, not as a process connected to the TTY. If you run from SSH like you are, Vino will only run until you end the session. And it is not going to start when the system boots. You are running it like a desktop application.

scottalanmiller

Also, even for just testing, you need a & at the end of the command.

Lakshmana

I need to run the service only in Putty.
I also need to see why the service does not run sometimes while using the VNC

Well then you can't have it running elsewhere already.

But you need to step back, this is the same issue you get all the time. You are "in too deep" and trying to get specific answers when you really have bigger questions.

Before we fix this... WHY are you doing this? WHY are you trying to run Vino from SSH?

scottalanmiller

In order to use Vino, you need to disable the existing VNC application.

sudo apt-get install dconf-tools

Then go into dconf and disable Remote Desktop Sharing. You can't run both at the same time.

But why is the existing VNC system not good enough? Why are you playing with Vino?

I am accessing one server from France(Eg) and I am from India.
I am taking the france server in India by the VNC viewer.
I have given only permission to take 3 session and I need to take the server in VNC by 3 sessions
I also need to access in Putty.
I have closed the 3 sessions from VNC viewer
After closing the sessions I cant able to take the server in VNC viewer.I have only VNC and putty.How to run the vino service at Putty now?

Same answer as above. You already have a VNC server running. Use the netstat command that I provided to see that. Vino cannot run if a VNC server is already running since port 5900 is already bound and unavailable.

I provided the link to the tool that you need to disable the existing VNC server so you can replace it. But I don't understand why you want Vino. You've not provided any logic for what you are doing. That you need VNC and SSH is fine, but that doesn't address why you don't want to use the included, running VNC server that you already have.

scottalanmiller

The question is around why are you replacing the built in VNC server, not why do you want VNC. I understand why you want VNC, you are using this as a remote desktop. Although VNC is rarely ideal for that. RDP and NX would be better. But nevertheless, why replace the fully managed, working VNC server?

scottalanmiller

Also, we should look at what Vino is... https://en.wikipedia.org/wiki/Vino_(VNC_server)

Vino is a VNC server for Gnome. But this is a thread about your replacing Gnome with XFCE. So using Vino makes even less sense here as this is a thread explicitly about you abandoning Gnome.

scottalanmiller

Vino comes from 2004 and is so active that its last stable release was two months ago and a preview release was just three days ago. Nice to see so many of these projects with so much activity on them.

Lakshmana

The customer need is to use VNC only as remote tools and putty as another option.
I have tested in my machine after four sessions the VNC is not able to connect.
I can use putty to run the above path to restart the VNC session

Understood, but how is this related to my question? My question is not why VNC or if it makes sense. I am purely asking why you are removing the VNC that is built into Ubuntu and replacing it with a different VNC. There is no need to justify wanting VNC. The question is not "Why VNC?", it is "Why Vino?"
