    SGI diffs Frequently Asked Questions (FAQ)

This is one of the Silicon Graphics FAQ series, which consists of:

    SGI admin FAQ - IRIX system administration
    SGI apps FAQ - Applications and miscellaneous programming
    SGI audio FAQ - Audio applications and programming
    SGI diffs FAQ - Changes to the other FAQs since the last posting
    SGI graphics FAQ - Graphics and user environment customization
    SGI hardware FAQ - Hardware
    SGI impressario FAQ - IRIS Impressario
    SGI inventor FAQ - IRIS Inventor
    SGI misc FAQ - Introduction & miscellaneous information
    SGI movie FAQ - Movies
    SGI performer FAQ - IRIS Performer
    SGI pointer FAQ - Pointer to the other FAQs
    SGI security FAQ - IRIX security

Read the misc FAQ for information about the FAQs themselves. Each FAQ is
posted to comp.sys.sgi.misc and to the news.answers and comp.answers
newsgroups (whose purpose is to store FAQs) twice per month. If you
can't find one of the FAQs with your news program, you can get it from

    ftp://viz.tamu.edu/pub/sgi/faq/
    ftp://rtfm.mit.edu/pub/usenet/news.answers/sgi/faq/

(rtfm.mit.edu is home to many other FAQs and informational documents,
and is a good place to look if you can't find an answer here.) The FAQs
are on the World Wide Web at

    http://www-viz.tamu.edu/~sgi-faq/

If you can't use FTP or WWW, send mail to mail-server@rtfm.mit.edu with
the word 'help' on a line by itself in the text, and it will send you a
document describing how to get files from rtfm.mit.edu by mail. Send the
command 'send usenet/news.answers/sgi/faq/misc' to get the SGI misc FAQ,
and similarly for the other FAQs. Send the command 'send
usenet/news.answers/internet-services/access-via-email' to get the
"Accessing the Internet by E-Mail FAQ".

You may distribute the SGI FAQs freely and we encourage you to do so.
However, you must keep them intact, including headers and this notice,
and you must not charge for or profit from them. Contact us for other
arrangements. We can't be responsible for copies of the SGI FAQs at
sites which we do not control, and copies published on paper or CD-ROM
are certain to be out of date. The contents are accurate as far as we
know, but the usual disclaimers apply. Send additions and changes to
sgi-faq@viz.tamu.edu.

  ---
  >   often desired by WWW presence providers. An IP aliasing is a step
  >   beyond a DNS alias, which is an extra hostname for the same IP
  >   address. HTTP requests do not include the host name, so a server has
  >   no way of knowing the host name to which a particular request was

  <   - Under IRIX 5.3/6.1 or later, use lpsched(1M) (part of the lp
  <     software), which can reportedly double as an lpr server. (See
  <     'relnotes print 3'.) We have no further information on this.
  < 
  <   - Under older IRIXes, or if you're used to it, use the lpr software.
  <     Set up your local printer as an lpr printer (see above) and edit
  <     /etc/hosts.lpd to grant access to the clients. Again, SGI won't
  <     support this.
  ---
  >   - Under IRIX 5.3/6.1 or later, you don't need to, because the lp
  >     server is also an lpr server. This is officially documented only in
  >     'relnotes print 3'. There are some caveats:
  > 
  >     - Don't define printers to the lp and lpr software (i.e. in
  >       /var/spool/lp/interface and /etc/printcap) with the same name.
  >     - Clients must be in ~lp/.rhosts or /etc/hosts.equiv; lpsched
  >       won't look in /etc/hosts.lpd.
  >     - lpd must not be running when lpsched starts up. If you want to
  >       switch from lpd to lpsched, do '/etc/init.d/bsdlpr stop;
  >       /etc/init.d/lp stop; /etc/init.d/lp start'. /etc/init.d/bsdlpr
  >       can't be chkconfig'ed off, so if you want to leave the lpr
  >       software installed you'll have to move /etc/init.d/bsdlpr to
  >       another name so it won't run on bootup.
  >     - The client must send the control file before the data file. Most
  >       Unixes do; some PCs do not. It might be informative to run lpsched
  >       with the -debug flag, or just try it and see if it works. lpd
  >       accepts either file order; lpsched should, and will in IRIX 6.2.
  > 
  >   - Under older IRIXes, or if you can't get the previous solution to
  >     work, or if you're a BSD head, use the lpr software. Set up your
  >     local printer as an lpr printer (see above) and edit /etc/hosts.lpd
