Thanks Eilko ,
I am currently using VPS remotely, which is using Fedora Core 2. I tried to psftp to do the things but it didn't work. May I have further instruction for that please? Also I need to install a file, which it is the file i need to add its path to the environment variable, to the /usr/lib directory in my VPS, but the permission for the directory is 755 rather than 777, so I couldn't upload it. I also couldn't change the permission by chmod. Do you have any idea to solve this problem as well?
Many thanks,
Best regards,
Joe
