FOSSTECH Notes

In Linux world, syslog has been doing a great job logging most of system and user activities. However finding information from log is not easy at all. With so much data in the log files, it can be a daunting task to just understand the log.  So with Tableau + syslog-ng, I decide to begin my journey of telling the story from log files. I called this project LogStory.  This first visualization is capturing when the user login, logout and the duration spent in the session. It will also show when the session is active and refreshed every 3 second.  You can view it live in http://tableau.fosstech.biz/ServerConn.html Username: logstory Password: A1r0plan3 What story should I tell next ? 

In order for Linux to perform ldapsearch over ssl, you need to import Active Directory CA certificate. On ActiveDirectory run the following command: > certutil -ca.cert adca.der Copy adca.der into the Linux server and convert the cert into Linux friendly cert #  openssl x509 -inform DER -in adca.der -out adca.crt Move the file into the default ca-trust directory # cp adca.crt /etc/pki/ca-trust/source/anchors/ # update-ca-trust You are ready to run ldapsearch over ssl to Active Directory Assuming you ad server is adsvr.fosstech.biz for fosstech.biz domain, you can run ldapsearch as follow # ldapsearch -x -W -H ldaps://adsvr.fosstech.biz  -D "administrator@fosstech.biz" -b "dc=fosstech,dc=biz" * Cheers!!! 📚 Want to Learn Docker?
