  • Ubuntu Linux Resources – It's a collection of tutorials designed to help new Ubuntu users, in particular those coming from a Windows-using background.
  • PsPasswd – Systems administrators that manage local administrative accounts on multiple computers regularly need to change the account password as part of standard security practices. PsPasswd is a tool that lets you change an account password on the local or remote systems, enabling administrators to create batch files that run PsPasswd against the computers they manage in order to perform a mass change of the administrator password.

    PsPasswd uses Windows password reset APIs, so does not send passwords over the network in the clear.

  • 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.

  • 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.

  • Baculaconf – Babel Services – What is Baculaconf?
    Baculaconf is a Web interface written in php and that use Web 2.0 technic. This interface is made to set up Bacula, the free backup software.This interface allow to configure one or many Bacula backup platform.
  • Perdition: Mail Retrieval Proxy – Perdition is a POP3, IMAP4 and managesieve proxy server. It is able to handle both plain-text and SSL/TLS encrypted connections, and redirect users to a real-server based on a database lookup. Perdition supports modular based database access. ODBC, MySQL, PostgreSQL, GDBM, POSIX Regular Expression and NIS modules ship with the distribution. The API for modules is open allowing arbitrary modules to be written to allow access to any data store.
    Perdition has many uses. Including, creating large mail systems where an end-user's mailbox may be stored on one of several hosts, integrating different mail systems together, migrating between different email infrastructures, and bridging plain-text and SSL/TLS services. It can also be used as part of a firewall. The use of perditon to scale mail services beyond a single box is discussed in high capacity email.
  • DeleGate Home Page (www.delegate.org) – DeleGate is a multi-purpose application level gateway, or a proxy server which runs on multiple platforms (Unix, Windows, MacOS X and OS/2). DeleGate mediates communication of various protocols (HTTP, FTP, NNTP, SMTP, POP, IMAP, LDAP, Telnet, SOCKS, DNS, etc.), applying cache and conversion for mediated data, controlling access from clients and routing toward servers. It translates protocols between clients and servers, applying SSL(TLS) to arbitrary protocols, converting between IPv4 and IPv6, merging several servers into a single server view with aliasing and filtering. Born as a tiny proxy for Gopher in March 1994, it has steadily grown into a general purpose proxy server. Besides being a proxy, DeleGate can be used as a simple origin server for some protocols (HTTP, FTP and NNTP).
