well, the scenario is, i have CentOS 5.2 based server running openssh, which gives sftp service to the outside users(from internet), the users from some public ip-addresses uploads and download files from sftp-server directories. I want that whenever a user uploads a new file in certain directory of server, the server should send me an email alert, kindly suggest how this is possible, and if somebody has a shell script for that, it will be a great favor for me, Regards
