Organization: A-lehdet Oy, Helsinki, Finland
Date: Mon, 7 Sep 1992 00:51:13 GMT

I am having problems using ipfilterd. The machine is connected to our
local ethernet and via slip to outside world, so it should act as a
firewall for the traffic coming from outside.

I have tried to define few allowed ports from outside, allow any
packets coming from our ethernet and mostly reject everything else.
There are some sample filters in the ipfilterd.conf file that comes
with the system. I have tried using them with no luck. "accept
ip.netCsrc 192.98.4.0" doesn't accept any packets (I have also tried
about the same with and without the macro and different parenthesis).
I have to list every host one by one to allow the traffic.

Is there anyone who has used ipfilterd and could mail me an example of
a working configuration file?

The machine is an Indigo XS24 running Irix 4.0.4.

Subject: DISPLAY environment variable
Date: 4 Sep 92 22:15:18 GMT


  Being new to X, I have a basic question:

  How do you propagate your DISPLAY variable so that you can display 
  on your local screen even through multiple levels of rlogin? 
  I've noticed that if you're sitting at host A and you rlogin 
  to B, the REMOTEHOST variable (sgi only, I know) is set correctly 
  and your DISPLAY is host A. But if you then rlogin to host C 
  from B, the REMOTEHOST variable is B not A and the DISPLAY is :0.

  So...

  Without REMOTEHOST, how do you carry your host's name through an
  rlogin connection? How is it done on non-sgi systems? 

  Thanks for any assistance,

Summary: children of cvusage don't inherit nondegrading priority
Organization: Computational Chemistry, ETH, Zuerich
Date: Fri, 11 Sep 1992 21:50:43 GMT

Normally, children processes inherit most important properties
from their parents.
If I have a shell started with a 'npri...' command, its
children inherit the non degrading priority as they should.
If one uses this shell and starts a job with cvusage like
  cvusage myjob
then myjob does not seem to inherit the non-degrading process
priority.
Amusingly, the cvusage process itself seems to keep the
non-degrading process priority.

This seems like silly behaviour.
Is it intentional ?
This is all happening under irix 4.0.5.

Not necessary (except for the mt command itself, of course, and that
is the default), unless you want to append multiple archives at the
'same' time without rewinding in between.  That is, a rewind is done
on close with the rewind device, never on open.

  Try : void _EditResCheckMessages();

The PaintJet is not yet supported by SGI, but it may be supported by
CAI's Freedom of the Press, which is a S/W PS RIP and includes support
for a ton of printers.

Remember that Showcase generates PostScript, and you'll need a PS RIP
to get that PS to a bitmap in order to print it.

Sorry if this has been asked before, but I would appreciate it if 
someone could answer the following questions about the demo program
"amesh":

  o  Is the source for "amesh" available on the net?  I have checked
     the usual sites, but was not able to locate it.

  o  The amesh binary appears to contain calls to the standard
     AudioLibrary routines as well as "open" and "ioctl" calls
     to /dev/hdsp/hdsp0{master,r*} (i.e. direct calls to the DSP
     subsystem).  I'm assuming that the calls to the DSP subsystem
     are issued from the modules within /usr/lib/libaudio.a and not
     from the amesh source.  Is this correct?  (That is, will I be
     able to write a program with similar functionality and performance
     using just AL calls?)

  o  Is the FFT being performed on the 56001 DSP chip or the
     R3000 CPU?  Is the FFT computed using integer (fixed
     point) or floating point arithmetic?

My application is in speech signal processing and recognition; I
would like to write a program which can, among other things, display
a near-realtime spectrogram (2D, not 3D).

Thanks very much in advance.

Unless you are running software programs that require the netls
(network software licensing program), you can turn this off.

To turn netls off, do the following:

	# /etc/chkconfig netls off
	# /etc/chkconfig llb off
	# /etc/chkconfig glb off

as far as netls affect your attempts to change your ip address, netls
does not have any control over that...

turn netls off and then try again (you did not say by what means you are 
changing your ip address ie by hand in /etc/hosts or via systemanager tool)...look for error messages in console and /usr/adm/SYSLOG...this 
will help

is sg25.aud.temple.edu (129.32.66.7): sgi/cap60/cap60pl126.tar.Z.

The aufs file server has an additional patch to allow volume stats on SGI
file volumes. Also several of the contrib subdirectories have patches made to 
allow compilation under IRIX 4.0. The entire source tree is built except for:

1. uab - since the configuration was built for IPTalk
2. AsyncATalk - which requires uab and BSD-style ioctl/terminal control stuff

For the default IPTalk configuration, all you need to do is untar the tar
file, and do a 'make install' in the cap60pl126/cap60 directory. Any
reconfiguration should not be a big deal.
 
We are on the east coast, and the distribution is about 5.5MB, so please try
to ftp it outside of the 9am-5pm EST time (6am-2pm PST).

I want to make it very clear: I am speaking for myself personally;
I know that many if not almost all of my organization feel otherwise!

I strongly dislike systems where I can not make the GUI's and menuing
systems "stay out of my hear"!  I feel them extremely hard to use because of
their inflexibility and obscurity.  Give me man pages and a command interface.

I own a AT&T 3B1.  One of the first things I did was disable the GUI, "ua".

I am quoting John H. Chauvin only to illustrate an opposing opinion to mine.
The material was picked for no other purpose.  I do not feel that his opinion
is "wrong" or should not have been stated.  I just disagree that GUIs improve
the usability of systems in general.

+ [The users]
+find it very comforting and it does ease the transition 
+to unix.

+My understanding is that most SGI users are "power unix users"
+who have no need for a GUI. Well if SGI want to expand its
+market share it must address the useability issue.
+(Other vendors are!) You can at least offer it. Users can decide
+for themselves if they want to use it.

I agree with what you said.  I disagree with your conclusion.  GUI's are useful
for people who want to do only a "few" standardized operations.  GUI's are
useful and work well in commerical environments where the firm wants to
minimize training time and wants its applications done in a standardized
manner.  Even I would strongly consider a GUI for this kind of usage.

When I am writing new applications or systems, I do not want to be bound
to whatever the author of a GUI thought the "five or six" kinds of operations
a computer is good for were.

Instead give systems good strong documentation (the famous RTFM) and a
flexible and powerful command interface.  Strong tools to make writing GUI's
easy may and should be added after that is done.

The system installation procedure should allow the installer the choice of
whether or not to install any GUI and the default should be not to install
one at all.  The system must remain usable and useful without a GUI.  It
is proper that a system may be more useful with a GUI than without one.
