• 12:22, 28 August 2023 Plinich talk contribs created page PostFix (Created page with "See [https://www.postfix.org/ the Postfix Home Page] for documentation and downloads (tho' CSG uses standard Debian packages so you really only need the web site for the documentation).")
• 12:14, 28 August 2023 Plinich talk contribs created page Lab computer (Created page with "Each CSE physical lab has multiple '''computer'''s, each of which is a New World host. To a very, very large extent the software suite installed on lab computers is identical to that on VLAB and login servers. The difference between the two is the size of the host and that physical lab computers only support one graphical login at a time.")

• 11:40, 28 August 2023 Plinich talk contribs created page PostgreSQL (Created page with "'''PostgreSQL''' is an open-source relational database product. It is used both for teaching and as part of the New UDB. It is available as a standard package in Debian.

Beyond providing Linux account information to hosts and workstations, it also implements a hierarchical class-membership structure which both allows users' roles in the school to be established, and also controls user access to certain resources. The New UDB loosely mimics this functionality to maintain compatibility across CSE's fleet of hosts. The Old UDB is deprecated because it is: # Old an...")

New World systems can, nominally, use <code>sudo</code> instead, which achieves the same result. However, many long-term users are more familiar with <code>priv</code> and there are a large number of priv scripts in existence which do still-useful things. In particular, some priv scripts are used insid...")

It transparently supports Linux-style file system semantics (user, group and other; read, write and execute), a significant benefit for undergraduate students who only need to learn that one set of semantics.")
