2.30pm – 2.45pm

Customary Self Introduction. People shared their experience with Free Software

2.45pm – 4.30pm – Gluster

GlusterFS is a scale-out NAS file system. It is free software, with some parts licensed under the GNU GPL v3 while others are dual licensed under either GPL v2 or the LGPL v3. It aggregates various storage servers over Ethernet or Infiniband RDMA interconnect into one large parallel network file system. GlusterFS is based on a stackable user space design. It has found a variety of applications including cloud computing, streaming media services, and content delivery networks.

GlusterFS has a client and server component. Servers are typically deployed as storage bricks, with each server running a glusterfsd daemon to export a local file system as a volume. The glusterfs client process, which connects to servers with a custom protocol over TCP/IP, InfiniBand or SDP, creates composite virtual volumes from multiple remote servers using stackable translators. By default, files are stored whole, but striping of files across multiple remote volumes is also supported. The final volume may then be mounted by the client host using its own native protocol via the FUSE mechanism, using NFS v3 protocol using a built-in server translator, or accessed via gfapi client library. Native-protocol mounts may then be re-exported e.g. via the kernel NFSv4 server, SAMBA, or the object-based OpenStack Storage (Swift) protocol using the “UFO” (Unified File and Object) translator.

4.30pm – 4.45pm

1. Introduction to Free Software

We start of with our regular discussion on the concepts and philosophy of the Free Software Movement and related topics.

2. Agenda : Gluster (High availability)

The Gluster architecture aggregates compute, storage, and I/O resources into a global namespace. Each server plus attached commodity storage (configured as DAS, JBOD, or SAN) is considered to be a node. Capacity is scaled by adding additional nodes or adding additional storage to each node. Performance is increased by deploying storage among more nodes. High availability is achieved by replicating data n-way between nodes.

3. Technical Presentation : Miniature computing device installation

Miniature Computing device configuration and installation based on the latest popular product on which GNU/Linux can be successfully installed and used as a complete computing device.

4. Q&A Session

This would be used to answer doubts that users have concerning Free Software.

We look forward to your participation for this exciting meeting. Hope to meet you all on Sunday.

Thank You

OpenVZ is container-based virtualization for Linux. OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

OpenVZ software consists of an optional custom Linux kernel and command-line tools (mainly vzctl). Kernel developers work hard to merge containers functionality into the upstream Linux kernel, making OpenVZ team the biggest contributor to Linux Containers (LXC) kernel, with features such as PID and network namespaces, memory controller, checkpoint-restore (see CRIU.org) and much more. OpenVZ tools (vzctl) is a solid alternative to LXC tools, see vzctl for upstream kernel for more details. While OpenVZ can be used with recent upstream kernel, we recommend using OpenVZ kernel for security, stability and features.
OpenVZ is free open source software, available under GNU GPL.

dSniff – Dsniff is a set of password sniffing and network traffic analysis tools written by security researcher and startup founder Dug Song to parse different application protocols and extract relevant information. dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf, and webspy passively monitor a network for interesting data (passwords, e-mail, files, etc.). arpspoof, dnsspoof, and macof facilitate the interception of network traffic normally unavailable to an attacker. The applications sniff usernames and passwords, web pages being visited, contents of email, etc. Dsniff, as the name implies, is a network sniffer, but it can also be used to disrupt the normal behavior of switched networks and cause network traffic from other hosts on the same network segment to be visible, not just traffic involving the host dsniff is running on. The name “dsniff” refers both to the package as well as an included tool. “dsniff” the tool decodes passwords sent in cleartext across a switched or unswitched Ethernet network.

ARP spoofing – is a technique whereby an attacker sends fake (“spoofed”) Address resolution Protocol (ARP) messages onto a Local Area Network. Generally, the aim is to associate the attacker’s MAC address with the IP address of another host (such as the default gateway), causing any traffic meant for that IP address to be sent to the attacker instead. ARP spoofing may allow an attacker to intercept data frames on a LAN, modify the traffic, or stop the traffic altogether. Often the attack is used as an opening for other attacks, such as denial of service, man in the middle, or session hijacking attacks.The attack can only be used on networks that make use of the Address Resolution Protocol (ARP), and is limited to local network segments.
