Consulting
We specialize in enterprise information technology (IT) infrastructure and networking for everyone from startups to large multi-national corporations, with a particular emphasis on network automation. We do everything from creating IT infrastructures from scratch, to analyzing and improving infrastructures that have been stretched to their limits by a company's growth, to combining existing infrastructures during international corporate mergers and acquisitions. Majordomo We are the home of Majordomo, one of the Internet's most popular free mailing list management packages, which was originally written by Great Circle's Brent Chapman. In addition to distributing the Majordomo software, we host the mailing lists devoted to supporting and developing Majordomo. List-Managers Mailing List We host the List-Managers mailing list, which is a platform-neutral forum for discussing issues related to managing Internet mailing lists, including (but not limited to) methods, mechanisms, techniques, policies, and software. |
Great Circle Waypoints Blog
We publish the Great Circle Waypoints blog for items of interest to Great Circle clients and friends, with a special focus on network automation. Presentations We're often invited to make presentations at professional events such as user group meetings, conferences, and workshops. Look here for copies of our presentation materials from those events. Building Internet Firewalls Book Great Circle's Brent Chapman is the coauthor of the critically acclaimed O'Reilly & Associates book Building Internet Firewalls, now in its second edition.

Firewalls Mailing List The Firewalls mailing list is the leading forum for discussions of Internet and intranet firewall security systems and related issues. We hosted the Firewalls mailing list from its creation in September 1992 until April 1998, and still host the list's archives from that period. The list itself is currently hosted by the Internet Systems Consortium. Other Mailing Lists In addition to List-Managers and the Majordomo-related lists, we have previously hosted other Internet discussion mailing lists. |
