Thanks every one for all your help, using VNC seems to be a good option for those who has no access to console and want to install Centos remotely, however just to test , I tried to upgrade Centos 4.5 to Centos 5, but it progressed almost to the end and then stoped with some error. nothing upgraded. I think I should first upgrade it locally and then start doing it remotely. fresh install will leave a lot of files from previous version, so it should not be considered at all. is there any log file that shows why upgrade failed ?
