BIND (Berkeley Internet Name Domain, previously: Berkeley Internet Name Daemon) is the most commonly used DNS server on the Internet, especially on Unix-like systems, where it is a de facto standard. Supported by Internet Systems Consortium, it was originally created by Paul Vixie in 1988 while working for DEC. A new version of BIND (BIND 9) was written from scratch in part to address the architectural difficulties with auditing the earlier BIND code bases, and also to support DNSSEC (DNS Security Extension ...

In the autumn of 2004, Bernstein began teaching one of the first formal university-level courses about computer software security, titled "UNIX Security Holes". The 16 members of the class discovered 91 new UNIX security holes. Bernstein, long a promoter of the idea that full disclosure is the best method to promote software security and founder of the securesoftware mailing list, publicly announced 44 of them with sample exploit code. This received some pre ...

To operate a DNSBL requires three things: a domain to host it under, a nameserver for that domain, and a list of addresses to publish. It is possible to serve a DNSBL using BIND, the popular DNS software. However, BIND is inefficient for zones containing large numbers of addresses, particularly DNSBLs which list entire Classless Inter-Domain Routing netblocks. DNSBL-specific software—such as Michael J. Tokarev's rbldnsd or Daniel J. Bernstein's rbldns—is faster, uses less memory, and is easier to configure than the general-purpose ...

The "open source" label came out of a strategy session held in Palo Alto in reaction to Netscape's January 1998 announcement of a source code release for Navigator (as Mozilla). A group of individuals at the session included Todd Anderson, Larry Augustin, John Hall, Sam Ockman, Christine Peterson and Eric S. Raymond. They used the opportunity before the release of Navigator's source code to clarify a potential confusion caused by the ambiguity of the word "free" in English. The 'open source' movement is generally thought to have begun with t ...

SPF normally only validates the domain of the envelope sender (listed as "Return-Path: " in e-mail headers). Domains that share mail senders (e.g. with virtual hosting) can forge each others' domain, and mail forwarding systems may also allow other domains to forge domains. SPF does not validate that a given e-mail actually comes from the claimed user, because it operates at the network level. SPF breaks inter-system SMTP forwarding (where an agent forwards e-mail to someone else without changing the "from" address). This is a problem ...

The proprietary term RBL is sometimes erroneously used in place of the generic DNSBL. RBL is a service mark of MAPS LLC. Some pieces of mail software have configuration parameters for the use of "RBLs" or "RBL domains", used to set the DNSBLs that the software should use. This may be trademark dilution. An RHSBL or Right-Hand-Side Blackhole List is a DNSBL which lists domain names rather than IP addresses. The term comes from the "right-hand side" of an email address -- the part after the @ sign - ...

Implementing SPF has two parts: Domains must identify the machines authorized to send e-mail on their behalf. Domains do this by adding an additional record to their existing DNS information. Receivers must request and use SPF information. Receivers request this information using ordinary DNS requests (which are typically cached to enhance performance). Receivers must then correctly interpret the SPF information. SPF does not specify how t ...

Normal SMTP allows any computer to send e-mail claiming to be from anyone. Thus, it's easy for spammers to send e-mail from forged addresses. This makes it much more difficult to trace back to where the spam truly comes from, and easy for spammers to appear to be senders the receiver would ordinarily trust. Many believe that the ability for anyone to forge "From" addresses is a security flaw in SMTP, and SPF is one of a variety of new ...

The SPF concept was presented at YAPC and OSCON (O'Reilly Open Source Convention) in 2003, in a short paper titled "Repudiating Mail-From" written by Paul Vixie in 2002. Vixie was the brains behind BIND, "Reverse MX" by Hadmut Danisch, and "Designated Mailer Protocol" by Gordon Fecyk. Originally SPF stood for Sender Permitted From and was sometimes also called SMTP+SPF, but it was changed to Sender Policy Framework in February ...

The definition of open source software was written to be almost identical to the free software definition. There are very few cases of software that is free software but is not open source software, and vice versa. The difference in the terms is where they place the emphasis. Free software is defined in terms of giving the user freedom. This reflects the goal of the free software movement. Open source highlights that the source code is viewable to all and proponents of the term usually emphasize the quality of th ...

The organization was formed in December 1997 to "provide IP registration services as an independent, nonprofit corporation." Until this time IP registration in the ARIN region was done by a department within the Network Solutions corporation, which provided the initial staff and computer infrastructure for ARIN. The first president of ARIN was Kim Hubbard, from 1997 until 2000. The current president of ARIN is Raymond Plzak. Until late 2002 it served Mexico, Central America, South America and all of the Caribbean. LACNIC now ha ...

The open source vs. closed source (alternatively called proprietary development) debate is sometimes heated. Making money through traditional methods, such as sale of the use of individual copies and patent royalty payment, is more difficult and sometimes impractical with open-source software. Some closed-source advocates see open source software as damaging to the market of commercial software. This complaint is countered by a large number of alternative funding streams such as: giving the software for free and in ...

The open source movement is a large movement of computer scientists, programmers, and other computer users that advocates unrestricted access to the source code of software. It grew out of licenses such as BSD, the ubiquitous access to Unix source code at universities. The line between the open source movement and the free software movement is somewhat blurry. Both are founded in the hacker culture. Mostly, the Free software movement is based upon political and philosophical ideals, while open source proponents tend to focus on more pragmati ...
