  • Baculaconf – Babel Services – What is Baculaconf?

  • 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).

  • NetHogs: What program is using that bandwidth? – NetHogs is a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to indentify programs that have gone wild and are suddenly taking up your bandwidth.

  • LiveUSB image with OpenBSD – carry your OS on a memory stick – It is trivial to a create a bootable USB stick with OpenBSD. I wanted to create one and realized that this will be of general use for anyone who likes a UNIX USB memory stick that they can carry with them on a keychain.

    If you wish to have LiveCD/LiveDVD instead, please refer to our other LiveCD-OpenBSD project on sourceforge!

    This USB image shall not touch your hard disk in any way. All the operations are done in the USB stick and main memory. Nothing will be written to your MBR or boot loaders!

  • Jon Hart’s Blog: OpenBSD on Soekris — A Cheater’s Guide – Below are the steps I recently used to get my NET4801 running OpenBSD 4.2 -current. The difference here is that I use qemu to make use of the considerably faster CPU on my desktop to breeze through the install and initial configuration.

  • Backup automatizzato dei database su SQL Express – SQL Server Express viene distribuito senza SQL Agent, quindi non è possibile schedulare internamente a SQL Server processi automatizzati, come ad esempio il backup. E’ però possibile aggirare questo ostacolo creando uno script ad-hoc, che si occupi dei vari job che vogliamo eseguire.
  • PacketFence: Open Source NAC (Network Access Control) – PacketFence is a fully supported, trusted, Free and Open Source network access control (NAC) solution. Boasting an impressive feature set including a captive-portal for registration and remediation, centralized wired and wireless management, powerful guest management options, 802.1X support, layer-2 isolation of problematic devices; PacketFence can be used to effectively secure networks small to very large heterogeneous networks.
  • teambox/teambox · GitHub – Open-source project collaboration software, available online for free. Inspired by Basecamp, Yammer, Twitter.

  • http://www.wormnet.nl/cprules – CPRules.html contains the description of the main program, how to create the html output from the Check Point files and how to influence the output.

    The program uses two supporting libraries and one supporting program. The first is specifically developed for this program to read and manipulate the Check Point databases in memory, called CheckPoint.pm. I hope to use this library for other projects involving Check Point FW-1 databases …

    The other library, Template.pm, is used for creating the html pages from a template, giving more freedom in designing the web pages. The author of this module is Sam Tregar (sam@tregar.com).

    The supporting program CPUsers.pl is to convert the exported userfiles to a CheckPoint database format to be used by CPRules. CPUsers.html describes how it works.

  • How To Calculate Bandwidth Utilization Using SNMP  [IP Application Services] – Cisco Systems – This document describes how to calculate bandwidth use with Simple Network Management Protocol (SNMP).
  • Long range WiFi antenna from Illy coffee can | John Graham-Cumming – I have a stack of half finished projects that I'm trying to complete. Happily, the first one was finished late last night: a long range WiFi antenna made using an empty coffee can. Working from the ideas here I made an antenna from the following:

    1. An empty 250g Illy Espresso ground coffee can

    2. A Type N bulkhead socket and a Type N plug

    3. A piece of WiFi antenna extension cable with a reverse SMA connector on the end.

    4. A short piece of coat hanger for the active element of the antenna
