Ubuntu/VirtualBox/OpenSuSE10.3/Full screen

Ubuntu 7.10/VirtualBox1.5.2_OSE/SuSE 10.3 x86_64

I have been playing with VirtualBox on OpenSuSE 10.3 and have been successful with Windows guest but, Ubuntu guest has been irritated me few days by resisting to be full screen mode. I have installed 'Guest Addition' and did everything I have seen from internet forum. But, all didn't work.

Finally, I found out the reason why it is. When I was installing 'Guest Addition', I just clicked the icon of installation script' file and I thought it's done. Today, I opened a terminal window and typed installation script name to run it and it turns out that I should be a root to install it. I've totally forgot about this.

So I used 'sudo' command to run it under root privilege and it works fine now.

CentOS5/Remote desktop

CentOS5/Remote desktop

Using remote desktop on CentOS5(RHEL5) looks simple until you face

'unable to connect to host: No route to host (113)'

error message.

This is caused by firewall setting of target machine, which is normally a machine you want to connect to.

Don't panic!

It's very simple. Login to the target machine and click the menu 'System/Administration/Security level and Firewall'

and click 'Other ports' then add 5900 port.

Once you have done so far, try again.
