hey friends, We are running 2 Centos servers 4.0 and 4.4 in our office for various activies like Mailing, Web Services, Database, CVS, FTP,Samba, Squid etc. We have about 100+ users on those servers , many users don't have shell on these servers (/sbin/nologin set as default shell) and some has shell (/bin/bash). We want to monitor the user activities of those users who have shell means what they all do on the server. One of the servers contains important data in the database and we don't want authorized users as they have access to this data and can copy this data to somewhere else like to their local systems. We want to track/monitor the activities of the users. Is there any free open source software available which can show daily /weekly/ monthly repots of the users activities. Please let me know if you need any further inputs. Regards Ankush Grover
