The following is a list of questions that are frequently asked about Solaris 2.x and later. Where the FAQ mentions "Solaris 2.x", it really refers to Solaris 2.x, Solaris 7 and later. You can help make it an even better-quality FAQ by writing a short contribution or update and sending it BY EMAIL ONLY to me. A contribution should consist of a question and an answer, and increasing number of people sends me contributions of the form "I don't know the answer to this, but it must be a FAQ, please answer it for me"; please don't send me those. Thanks! As you may have noted, I have switched employers and work for Sun as of April 1st 1995. Sun is in no way responsible for the contents of this FAQ. The latest Solaris 2 FAQ, including an HTML version, and some other goodies |can be obtained through ftp from <ftp://ftp.science.uva.nl/pub/solaris>. A new version of the FAQ is available with an index separate from |all questions, it's <http://www.science.uva.nl/pub/solaris/solaris2/>. So it's a lot quicker to download. Also, an experimental FAQ search service |at <http://www.science.uva.nl/cgi-bin/sfaq.cgi> is now available. Please note that these addresses have changed because of a reorg. Just |replace "fwi" or "wins" in the old addresses with "science". |The HTML <http://www.science.uva.nl/pub/solaris/solaris2.html> version of the FAQ contains references to most FTP sites and files mentioned in the FAQ. The references to ftp sites are always to either HTML files or directories, never to binary files. I've added an index of questions and marked changed(*) and added questions(+). The FAQ is being reorganized, time permitting. The index is generated automatically, so there may be errors there. Not all questions are in the section they belong in. Suggestions on how best to subdivide/order the FAQ are welcome. 1.
