Nuxsl
nuxsl is a distributed, muti tier, client server communication tool which enables you to centralize your auditing of user shell accounts under a broad wide range of unix computing environments.
Every audited server gets a nuxsl client installation and communicates encrypted over a dedicated and registered tcp port with a central nuxsl master process, best placed on a server with restricted access.
A graphical frontend running under linux enables you to analyze the audit logs using very fast direct access to the database. Additionally there is a web based frontend under development.
The commercial or productive use has to be licenced for every audited server, home, education or evaluation is free!
The fully supported platforms include Intel Linux 2.4, Sparc Solaris 8, Intel Solaris 2.6, Intel freeBSD 4.5, Tru64 5.1, HP-UX 11.0, IBM Aix 4.3 and even MacOS-X.
Additionaly there is a version for IBM s390 Linux.
Under development are versions for SGI Irix.
