unable to connect to host: connection refused (11061)

[Sonali Tamhankar]

Thanks James, Stewart and Raj for your messages!

Switching the ssh -L command around helped. I had tried it before, but I
think I was doing another silly thing that was causing the problem: I
was typing localhost :0 instead of localhost:0. The space was creating
the problem, I guess.

I couldn't start "vncserver :0" on my work.machine because of a
/tmp/.X0-lock file belonging to root that I could not remove. Typing
just "vncserver" on work.machine automatically chooses :1. When I type
"vncserver :0", after the warning about .X0-lock file, it also says "A
VNC server is already running as :0". This is confusing, because ps does
not show any instance of Xvnc associated with it.

I don't think I'll need to run vncserver on my home computer, but if I
did, how would I resolve the conflict of both ssh and vncserver using
the same port? Could I type "vncserver :2" on my home machine?

By the way, when I only downloaded vncviewer, somehow it never gave me
the window to set up password, nor could I find an option where I could
set it up. That is why I downloaded the server, but made it a point to
not start the server on my home computer (I did this once on another
computer, and the vnc was simply making infinite copies of itself!)

Thanks for all your help!

Cheers,
- Sonali.

Your ssh command takes local port 5901 from your home computer, and
forwards 
it to port 5900 on the work computer.  However, your work computer is 
listening on port 5901.  Also, your VNC command wants to connect to port

5900 on your home computer, which isn't doing anything.  (This leads me
to 
guess that your home PC is not running a VNC server, correct?). 
Assuming 
that your ssh connection is successful, and that your work machine
permits 
you (that is, the me "at" work.machine user), then all you need to do is 
correctly match up your ports, which you can do by either, but not both,
of 
the methods below.

Either:

On the work machine type "vncserver :0" or just "vncserver" to start it;
it 
will then listen on port 5900.  When you connect, type "localhost:1". 
This 
option will means that your work machine will listen on the expected
port 
form VNC, and also that you can run a VNC server on your home machine
that 
also listens on port 5900 that will work correctly when the ssh
connection 
is established.

Or:

Change the ssh command to: "ssh -L 5900:localhost:5901 me "at" work.machine".

Note that this option will create a clash with a VNC server running on
your 
home machine on the default port, should you decide to set one up, since

both the VNC server and ssh will try to listen on that port.

Doing both of the above will cause the problem you had before to
re-appear, 
since you will have swapped ports at each end.

Also, like Jaroslaw said, make sure that your ssh server permits
tunnelling. 
If it is not permitted, you won't get any messages to that effect when
you 
start ssh: the terminal side will still function but the tunnelling part

will be silently dropped.

Hope this helps,
