Resultat from the web, "sudo /usr/sbin/webpasswd billy 12345678" and from the error_log, "couldn't read file "./usr/sbin/webpasswd.": no such file or directory". .Mike

Notice that "." is being appended before the path, which turns it into a relative path. It looks like safe mode might be on. Create a new PHP script with nothing but the command "phpinfo();" in it, and view it in a browser. To see if safe mode is on, look for the setting "safe_mode". The line below it is "safe_mode_exec_dir". If safe mode is on, you'll need to put your program ("webpasswd") into that directory to execute it. Regards, Adam Zey.
