I dont understand how to chmod or set file permissions, can you please explain?
Answer:
chmod is a unix program enabling you to set or assign permissions to files. You can do this from telnet/ssh or via FTP program. Most FTP programs supports the setting of file permissions. In Unix/Linux all files has ownerships with specific permissions for files.
The easiest way to set permissions of files is to use your FTP client. Your FTP program will have some menu item or button to change the file attributes/permissions of files. You can also normally set the permissions of files by right clicking them from your FTP program.
