RE: [PHP] Interactive Commands

1. build a new php binary, have root and only root own it. 2. if you want, setup a new extension in apache to parse php documents using the new binary 3. write a few test scripts, make sure it works 4. to change your password: <?php system("echo '$new_passwd' | passwd $username --stdin"); ?> works here marco -----Original Message----- From: Mukul Sabharwal [mailto:mukulsabharwal@yahoo.com] Sent: Monday, October 23, 2000 7:26 PM To: szii@sziisoft.com; pour@mieterra.com; joe@conway-family.com; php-general@lists.php.net Subject: Re: [PHP] Interactive Commands Hi, Well... I telnet(ed) into my account.... as per replies.... i tried chpasswd... not a valid function.. passwd oldpass newpass verify also doesn't work, for the simple reason that \n needs to be there.... but i can't seem to get it right..... what's a TTY ? http://www.plesk.com ... Plesk does almost what I want to do .. changing passwords, etc. though you need to have control over the server in that case...but what if i am the root.... how do i change the password... which is just an example... how do i make it more interactive ? thanks. > You may need to use special tricks to change > passwords.
