In this talk Kyle Rankin will provide an introduction to performing forensics analysis on Linux machines using the popular Sleuthkit tools with their easy-to-use Autopsy web-based front-end. The talk will cover initial installation and configuration of Sleuthkit and Autopsy, basic concepts and considerations for a forensics investigation, and at the end there will be a demo with a real, compromised Linux image.
Talk starts at 7pm; show up by 6:10pm if you want to get in on the pizza order.
GlusterFS is a cluster file system with some unique characteristics, it has enterprise class features and is free, it uses chaining to customize it’s features to your specific needs, and it has a fast and open development team that’s very responsive to user requests. Some of these features make it very useful in high availability and load balancing environments. It’s not without it’s problems, though, and deciding when GlusterFS is feasible and when it isn’t can be a hard choice. This discussion will cover the features of GlusterFS, along with when it is and isn’t the right choice for your clustering needs.
The focus f this meeting will be LTSP implementations, how they are used, what OS components are utilized, and what happens in an LTSP boot from start to finish. There will also be discussion of LTSP’s role in centralized computing and green computing initiatives. The general steps that need to be accomplished to setup an LTSP installation will also be covered.
Red Hat Directory Server / CentOS Directory Server provides an easily administered and robust solution for entities needing an enterprise class LDAP system. With support for 4 way multi-master replication, easy integration into the Red Hat suite of systems, and comprehensive documentation, it’s a good choice for both deploying a new LDAP structure and migrating from an existing one.
Covered topics will include:
Implementing redundancy through multi-master replication
Configuring clients to connect to LDAP for single sign on
Using pGina to provide LDAP auth for windows
Using Samba to provide single sign on for windows through native windows client
After attending this talk a system administrator of moderate experience with windows and Linux should be able to implement single sign on for a small heterogeneous network with little effort.
Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on thousands of clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes.
