Dear Faculty,

As part of our summer activities we are ready to move all faculty onto
your new server purchased by the CER grant over a year ago.  This new
machine is an HP 9000/730 which has a faster processor than the existing
piper.  HP-UX is a not the same as SunOS so some commands will be a 
little different. At the end of this message is a list of possible 
"gotchas." User programs that previously ran on piper will need 
to be recompiled.

We are planning to make the new machine (currently called newpiper)
the "real" piper on Aug 14th.  At this time the old piper (the SUN)
will be renamed "oldpiper."  We will officially decommission oldpiper
(the SUN) on August 31, 1995.  

You are encouraged to login to newpiper as soon as possible.  We'd
like to fix any migration problems before the actual switch-over.
Note that newpiper uses the new filesystem layout (as will all
CSops machines in the near future).  This means that many
things that you might expect to be in /usr/local/bin reside
in /Tools/bin and packages that used to live in /usr/local/PACKAGE
now live in /Tools/PACKAGE.  Mail was sent out about this change
several weeks ago.

If you have any questions let us know.

thanks & good luck.

--------------------------  FAQ ---------------------------------
The following is a list of potential problems/differences users
may encounter presented in a "question and answer" form.

Q) Why is the output of "df" different.  It's a lot less useful.
A) This is an svr3-based "df".  To get a BSD-style df, use
   the "bdf" program.

Q) When I login to newpiper I get an error from "stty".
A) The "stty" command on HP-UX does not support some of the
   flags the BSD "stty" supports.  You will be unable to
   use the following flags: dec new crt
   In most cases you can remove these flags and not notice any
   difference (when you remove the "dec" flag you may need
   to add 'erase "^?"' to the stty line to get the same
   erase character).  For more info, do "man 1 stty" for
   a list of valid options.

Q) When I try to run "vi" or "more" half the screen scrolls by.
A) This should only be a problem if you rlogin or telnet
   to newpiper from an xterm window.  You'll need to do
   "eval `resize`" to set the window size correctly (HP-UX
   does support SIGWINCH but the utilities only honor
   LINES and COLUMNS environmental variables).  You
   may want to add the following to your .login file
   (assuming your shell is csh):
	if ( $term == "xterm" ) then
	    if (`uname` == "HP-UX" ) then
		eval `resize`
	    else
		resize
	    endif
	endif
    This will set the screen size correctly for HP-UX as
    well as other versions of Unix.

Q) When I start up an xterm delete (or backspace) doesn't work
   and neither does ^C (control-C).
A) You started up an xterm that is not set to be a "login shell."
   The problem is that this means your .login file is not read
   and the default erase, interrupt, and kill characters in
   HP-UX are (probably) not what you want.  You need to
   either start all xterms with the "-ls" flag (means LoginShell)
   or add the following line to your .Xdefaults file
	XTerm*loginShell:             true
    which will make all xterms startup as login shells.  This
    is the easiest to do and is what we suggest.

Q) I can't get my programs to compile on the new piper.  What
   can I do?
A) HP-UX does provide a BSD compatibility library (-lBSD) but
   it does not include many things.  You should take a look
   at /tools/cs/doc/Porting_BSD_to_HPUX.txt which has lots
   of good info on porting programs to HP-UX from a BSD
   environment (like SunOS).

Q) I can't find many of the programs I used to use on piper.  Where
   did they go?
A) As was mentioned earlier, newpiper follows the new CSops filesystem
   layout.  This means that most commands (with the exception of
   those necessary for booting the machines and performing maintenance)
   have moved out of /usr/local.  Most of /usr/local/bin has moved
   to /Tools/bin and packages that used to be /usr/local/PACKAGENAME
   are now /Tools/PACKAGENAME.  Also, links from /usr/local/bin
   to binaries in other packages have been removed (they are impossible
   to keep current).  This means you may need to add packages to
   your path.  For instance, to get at emacs you need to have
   /Tools/emacs/bin in your path.  To get at rn, trn, or tin
   your need to add /Tools/news/bin to your path.  This was all
   spelled out in mail sent a few weeks ago (and posted to netnews
   as well).  There is more info in the file
   /csops/FAQ/new-tools-structure.howto.  If you are interested in
   more of the nitty-gritty details you may want to read
   /csops/FAQ/new-tools-structure and take a look at
   http://www.cs.colorado.edu/~mikef/rfc/host-localization.html.

Q) The "ps" command doesn't work like it used to.
A) The sysV-based "ps" HP-UX uses takes very different
   flags and produces different output.  Do "man 1 ps"
   for more info.  When you used to do "ps aux" you would
   now do "ps -ef" and when you used to do "ps auxww" you
   can do "ps -elf".
