1) Probably you don't have access to those directories you want to put tha file in. I don't think you will find a writeable directory in safe mode, though.

2) There's a recent mysql bug that allows you to bypass safe mode, and read anything from the server, if the sql server and the file server is the same.

1) Coppermine can upload so that this directory is writeable
2) yes,i know but i dont have any mysql account in server because i cant view file Laughing ,only /etc/passwd via posix_getpwuid
i think when i get passwd,i only have a solution to brute force password
Any idea Laughing

Yeah.Paranoic admin.OK.
Try first phpinfo(); Look full path to the your site.Then use readfile('/home/blabla/file.php'); to read files.Try do upload perl shell into cgi-bin directory.
