BINGO
I found the solution
I did telnet. Eventually root/sifteam worked
in telnet write "passwd"
it asks new password, write : ipbox
it says too short but dont worry about it, write again "ipbox"
and bingo...
then ftp your ipbox with root/ipbox
go var/etc/httpd.conf edit it
Add your USER
ASSWORD Example: "/:root:ipbox
and you good to go
