Love the idea of a password on a P0wnyShell, just want to create my own login interface. This is a simple PHP shell with a login interface. The NotFoundShell with not found page is a good idea, but not useful in CTFs.
My default password atm is monkey, but you can change at the top of the monkeyshell.php file. I changed hash functions to sha256.
Features are the same as NotFoundShell/P0wnyShell (Big thanks to the creators of those shells) :
Command history (using arrow keys ↑ ↓)
Auto-completion of command and file names (using Tab key)
Navigate on the remote file-system (using cd command)
Upload a file to the server (using upload <destination_file_name> command)
Download a file from the server (using download <file_name> command)
Disconnect from PHP Shell (using logout command)
Have fun in CTFs !
