  • DNSViz | A DNS visualization tool – DNSViz is a tool for visualizing the status of a DNS zone. It was designed as a resource for understanding and troubleshooting deployment of the DNS Security Extensions (DNSSEC). It provides a visual analysis of the DNSSEC authentication chain for a domain name and its resolution path in the DNS namespace, and it lists configuration errors detected by the tool.
  • intoDNS: checks DNS and mail servers health – IntoDNS checks the health and configuration and provides DNS report and mail servers report. And provides suggestions to fix and improve them, with references to protocols’ official documentation.
  • Master & Slave PowerDNS – LinuxManage.com – In this short tutorial we will show you how to configure powerdns running as master and slave. For this tutorial purpose, master powerdns host will have ip address 192.168.56.3 and hostname ns1.example.com, slave ip: 192.168.56.4 and hostname: ns2.example.com
  • Sendmail relay configuration on AIX | Leave No Bit Unturned – This document describes how to set up a Sendmail e-mail gateway or relay which will be able to process incoming mail and route it to different mail servers based on domain information. The routing table is based on the Sendmail mailertable feature instead of the usual MX record based routing. This will come handy when there is a need to route mail internally in a different way than externally.

  • carloslima/dhsnapshot · GitHub – This script was created out of the need to have snapshots-like backups using the DreamHost Backup service, which provides 50GB of space for personal backups but gives very limited access to it's servers. Basically, you have no SSH access, only RSync and SFTP. It can be used to backup any machine: your computer, a server or even a Dreamhost-hosted website. You just need to configure it with the path to backup, your dreamhost backup account and the private key used for authentication and it will create daily backups and keep the last 7 days, 4 weeks and 6 months.
  • palexander/dreamback · GitHub – Dreamback is the easiest way to automate your backups on dreamhost. Dreamhost does not guarantee their backups of your users (though they've saved me with backups before), so it's best to run backups yourself. This is beta quality software. Please report issues if you have them. Using Dreamback is easy: 1) Create a user on dreamhost to manage your backups 2) Log in with your new user 3) gem install dreamback 4) dreamback 5) Answer the questions to setup your automated backup
  • View all MySQL Variables for Pasting into my.cnf – This is really useful for me because I work with dozens of different database servers. The first thing I do is run this command and paste it into the servers /etc/my.cnf file. That way I will always know the original value and it just makes life much easier.
  • How Permissions Work – Permissions are a key component of the Windows Server 2003 security architecture that you can use to manage the process of authorizing users, groups, and computers to access objects on a network.

  • Netl33ts: Cisco VPN Troubleshooting Guide – It is important to understand how IPSEC works in order to understand how to troubleshoot a VPN connection. This is a quick overview of IPSEC and is by no means a complete detailed guide.
  • TunnelsUP: Home – Welcome to tunnelsup.com! This site aims to document how to set up, troubleshoot and understand everything to do with Cisco VPN concepts. Here you will find scripts for putting together a tunnel, troubleshooting tips and videos that will teach concepts and demonstrate various VPN technologies.

  • Wifix – Non-technical version

    WiFix is a program that allows users to locate, download, compile and install the appropriate driver for their wireless card.

    Geek version

    WiFix is a community-built program that aims to be a modular program that provides users with an intuitive interface for installing wireless drivers. Although created for Linux in general and Ubuntu in particular, the design is intended to allow for usage on all Linux distributions and other platforms, such as BSD or even Windows, potentially using the same database tables. For example, archives used for installing NDIS-based drivers can work in any of these operating systems.

    When users run WiFix, their device information is submitted to our database, the PCI ID is stored, so that may locate the appropriate driver. When the same device id is queried again, the driver is retrieved and installed. In a sense, WiFix is a program by users, for users; every time someone uses it, it gets a little bit better.

  • MQTT and Arduino Devices – IBM Redbooks – The number of different types of devices that can benefit from MQTT implementations is growing every day. This paper shows how to use MQTT directly from the Arduino platform.

    [PDF]

  • MQTT: MQ Telemetry Transport – MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers (more…)
  • SoftPerfect Network Scanner: fast and free network scanner – SoftPerfect Network Scanner is a free multi-threaded IP, NetBIOS and SNMP scanner with a modern interface and many advanced features. It is intended for both system administrators and general users interested in computer security. The program pings computers, scans for listening TCP/UDP ports and displays which types of resources are shared on the network (including system and hidden).
    In addition, it allows you to mount shared folders as network drives, browse them using Windows Explorer, filter the results list and more. SoftPerfect Network Scanner can also check for a user-defined port and report back if one is open. It can also resolve host names and auto-detect your local and external IP range. It supports remote shutdown and Wake-On-LAN.

  • davidtv – PAC Manager, Perl/Gtk approach to connections managing
  • PAC Manager | Free software downloads at SourceForge.net – PAC is a Perl/GTK replacement for SecureCRT/Putty/etc (linux ssh/telnet/… gui)… It provides a GUI to configure connections: users, passwords, EXPECT regular expressions, macros, etc. You like 'SecureCRT/SSHMenu'? Check this tool and let me know
  • Build a file server with the Raspberry Pi | Linux User – We’ll be using Arch Linux as the operating system for our file server, because it is small,and has only the minimum packages required for a working system. This means that we can set up the file server without wasting resources on a graphical user interface and other unnecessary packages. Arch Linux comes with hardly any RAM allocated to the GPU by default, which is exactly how we want it for use as a headless server.
  • Registry Settings that can be Modified to Improve Operating System Performance – This section provides a description of recommended values for several registry entries that impact operating system performance. These registry entries can be applied manually or can be applied via the operating system optimization PowerShell script included in Windows PowerShell Scripts.

  • Your Soekris OpenBSD as a OpenVPN appliance | Me in IT – I have an existing network at home, but would like to be able to connect to it using a VPN every now and then. This enables me to access the fileserver, printer and so on.

    My network contains an Apple Time Capsule as a nat router, an ethernet modem provided by my cable company Ziggo and devices such as laptops, that use the network.

    A Soekris box I had lying around meets all requirements perfectly for a VPN-server. Here is how to set it up.
