Can VNC run under LAN?
 

I have test it ,It can log in 211.*.*.*from a LAN ,but can't log in a remote machine who's Ip is 192.*.*.*
What can I do ,if I wan to rlogin a machine which is under a LAN using VNC?

Thanks in advance!

yes vnc can run on a lan, as long as the server can talk to the client and vica versa
all you have to know is the ip (or hostname) and the vnc desktop number you want to connect with (and of course tha password for that display)

really ?? That would be fine !! Thank you ,
But how can I know it's desktop number ?
what desktop is ??
and does the format of the order is" ip:<desktop num>"? ?
is desktop num the num of port ?

if you can ping the two machines, then vnc should work. the format is:
vnc ip:num
if you want to find out what number the server is running on, try:
nmap localhost

I think I've known desktop, but ,the OS system I use are all windows , It did't show me desktop num . desktop num only appears in linux or unix , I don't know if I am right ,

192.168.x.x is going to be a reserved IP address, you might need to forward the VNC ports through the firewall to the real world IP address usually 5800-5900.

thanks for all your help,,It's quite useful!
But,where can I input the port which is between 5800-5900 ?
and the format ?
I've never seen a option which ask me to input the port !
any step by step turorial???
thank u very much !!!

the vncserver will tell you what desktop nuber ir is running on, or you can speciy as well
