I've tried this command:
And doesn't return any response and no error.Code:vncviewer -listen
Does not allow vncviewer command line parameters?
Then you can use x11vnc on the N900 and xtightvncviewer on a Linux Computer.

The VNC viewer provides a client that can connect to a VNC server running on a different system and display its desktop.
vncviewer --help
Therefore, I think that vncviewer has no server mode.
But I don't see a difference which computer starts the connection (client/server role). It's only important that the computers can connect.

If you want to see the N900's screen on a computer:
x11vnc on the N900, vncviewer on the computer
If you want to see the computer's screen on the N900:
vncviewer or rdesktop on the N900, x11vnc or RDP on the Computer
If you want to see the N900's screen on the computer and the computers screen on the N900..
x11vnc and vncviewer on the N900.. x11vnc and vncviewer on the computer....
Which scenario are you trying to do?
x11vnc on the N900, vncviewer on the computer

I want to see any PC's screen on the N900, but also when computer is behind a firewall and not my N900.
This is the main utility of the reverse VNC (server behind any firewall).
Replacing N900 by a notebook, I actually run this in my notebook (which has a public IP or open firewall):
And people who wants to receive remote support runs this in the PC:
The x11vnc and vncviewer ported to Maemo/ARM are modified from the standard packages, and don't seem to support command line parameters.

You can define a firewall rule for that on your PC.
Another option is to tunnel VNC port 5900 through ssh.
That means the PC connects to your N900 via ssh:
Code:
ssh -R 5900:localhost:5900 user@n900
On your N900 you connect vncviewer to 127.0.0.1 (port 5900).
If you want to read more, check:

By the way, it might not be a good idea, that your N900 does not have a firewall.

(with open firewall I meant open port in the firewall)
Ok, the VNC connection with the SSH tunnel works for me (I still miss command line way to call vncviewer with destination)

Oops!
I cannot give my user&password to other people to stablish SSH tunnel! This would be a big security hole!

1. Add a new user on your N900 as root.
Code:
sudo gainroot adduser friend
Code:
vi /etc/passwd friend:xxxxxxxxxxxxx:1000:1000:,,,:/home/friend:/bin/false
Code:
ssh -R 5900:localhost:5900 -N friend@n900
Code:
passwd friend
Code:
iptables -F INPUT iptables -A INPUT -i wlan0 -p tcp --source 192.168.1.1 --dport 22 -j ACCEPT iptables -A INPUT -i wlan0 -p tcp --syn -j DROP iptables -A INPUT -i wlan0 -p tcp --source 192.168.1.1 -j ACCEPT iptables -A INPUT -i wlan0 -p icmp -j ACCEPT iptables -A INPUT -i wlan0 -p udp --source 192.168.1.1 -j ACCEPT iptables -A INPUT -i usb0 -p all -j ACCEPT iptables -A INPUT -i lo -p all -j ACCEPT iptables -A INPUT -j DROP
Start the firewall automatically on the N900:
Code:
vi /etc/event.d/iptables # iptables at start start on startup exec /path/to/iptablesConfig
