Creating a multi-purpose file server for SOHO business environments with NetBSD, Samba, NFS, and Vsftpd
In the UNIX world, there are different ways to implement file and folder sharing. In particular, in this article we will address two architectures with respect to sharing in the local network: NFS service, historically used in UNIXlike OSes, but now also running on Windows platforms and the Samba service (currently known as CIFS) typical of Windows environments. In order to manage access to files remotely, the choice fell on the vsftpd
daemon configured properly in order to interact with SSL certificates and establish encrypted tunnels in which to flow the traffic data; for example, for connections of type “roadwarrior”.

DragonFlyBSD As Backup Servers in HIFX
DragonFlyBSD, the fork of FreeBSD by founder Matthew Dillon with the long-term goal of providing transparent single system image clustering, supports both the IA-32 & AMD64 platforms. Previously including pkgsrc from the NetBSD project as the package management system, it has recently switched to native Dports, DragonFly’s own third-party software build system, based on FreeBSD’s Ports Collection. This article will describe how HIFX (hifx.co.in) uses DragonFly for its backup servers, leveraging the features of its HAMMER1 file systems; namely remote mirroring, snapshots, pruning, and dedup in two particular use cases.

Network Analysis On a Storage Area Network Using Wireshark
Wireshark, originally known as Ethereal, is probably the most famous open source packet sniffer and network analysis tool available. This application supports about 1300 protocols through a vast number of filters. Functionalities such as traffic, protocol analysis, and packet dissector make it an extremely versatile tool for security experts, network engineers, and system administrators. This article provides a quick overview of using Wireshark in a SAN environment. Although, network analyzers are powerful software and can be used to troubleshoot complicated issues, at the same time, they
can be extremely dangerous when misused or activated through unauthorized access.
