It _is_ an opportunity to talk to USL people.  It should _not_ be looked
at as an occasion to yell and scream at them.

If 50 people a day come to their booth and say "The USL suit against BSDI
is making you look _really_ _bad_", that will get noticed.  If you staff
a booth at a trade show, its your _job_ to tell your employer when people
are saying stuff like that.

But resist the urge to say "You're all a bunch of assholes!!!"  The people
you talk to didn't cause this and don't deserve to take the heat for it.

Be nice and you might get your point across.  Be nasty and you just turn 
them against you.

I have a customer ( a big one ) that is in search of a method of tranfering
his cpio data on existing tape to a tar tape. I know, I know, I know. He  can
cache the data to disk, then tar  it to another tape . Is there  another way?
Does anyone have the source handy that can read the cpio file format from raw
file and replicate it in tar format on another tape. I know this method would
also have problems because of the way tar treats hard links and symlinks (Which
he would  have to deal with). How  about some fancy piping and redirection of
file descriptors?  Thankx for any replys in advance.

What you build depends on what you want to do, but I have a generic econo-buy
PC with a cheapie SVGA card and a couple of IDE drives (in other words, a normal

Is there anyone out there who has built a Unix box and could tell me
about their experience.  

I have been thinking of building because I believe it is cheaper and
more flexable than buying.  I'm planning to use the GNU Hurd, when it
eventually emerges, GNU applications/utilities and X with gwm.

It seems that the easiest way would be using components intended for
powerful DOS machines, since they are widely available.  I'm curious if
anyone, as an amateur, has constructed a box with a design different
from the PC standard.

My dream would be to use some Inmos Transputers but I think this would
conflict with my goal of minimal cost!

Any coments?  (Email preferred - I'll summarise and post.)

Organization: Colorado School of Mines

Hi,

I don't know if this is the right place to post this, but
I need some help about writing a simple client/server program.

Here is what I am trying to do;

I want to write a program that will accept connections from
other programs and will communicate with them without forking.
I don't want to fork because the info should be generated on one
program, send to server and the server has to respond to every
program connected with the same info( if I fork, how  can I transfer
that info to child?).

  main                     main
  client <--> server <--> client
                |
                |
         _______________________________
         |         |        |        |
         v         v        v        v
       client1  client2  client3     ......

(main clients generate the info)
I know this is not an easy thing to do, but actually, I am having
problems with accept(..);
can I do something like this;

while(1)
{
 check_new_connection(); /* how can I check if there is any new
connection
                           without waiting, as far as I know accept(..)
                           blocks you 'till you get some connection*/
 check_clients();       /* I can do these, no problem. read if there is
                           any new info */
 if(thereIsNewInfo)
   inform_clients();     /* if I can create a list of handles for clients
                           this is no big deal */

}
My problem is getting new connections without waiting.

I appreciate any help.

Subject: How to avoid calling time(2)
Date: 27 Jan 93 19:53:09 GMT
Organization: CPIO S.A.


Hi wizards!

I run many applications that need to call very often the time(2)
system call. I do not see how I could design my programs to do without
having to get the result of time(2) very ofen.

But I wonder if there is a way (on a 486 running Dell Unix 2.0 at
least) to get time information without having to do a system call each
time.

For instance, does someone know if I can get a pointer toward the
value of time that is stored somewhere in the system ? Of course this
should work with processes having no suid bit set nor running as root
and files like /unix or /dev/kmem must stay to be not readable by
anyone :-)

Or am I going the wrong way because the time(2) system call is so
light that I should try to find other means to reduce the impact of my
applications on the system ?

Any comment or hint welcome !

	Thank you !

Other than debugging a new mail system, the only time I ever

do you have a policy saying what they're doing is wrong ?
do you have a policy stating what the process is if you see such acts?

if the answer to both is not 'yes', you've got a problem.
if the answer to both *is* 'yes', you've answered it.

Given that USL does not own Usenix, and that you have the right to free
speech, I would dare say that doing so would expose USENIX to a rather
expensive legal adventure known as a lawsuit.

I've given SCO and other vendors a hard time at trade shows several times;

Lucky you.  I just learned the answer to this question last week.

If your sockets are...

Blocking... then just wait for a read to return zero bytes, indicating a
broken connection.  I don't use blocking sockets, so I have no
experience with this method.

NonBlocking... Watch for select() to claim that one of the sockets can
be read from by setting the appropriate descriptor bit.  Then, when you
go to read the socket via a non blocking read, you will get zero bytes
back when the socket connection is broken.  Keep in mind that normally,
a zero means, "No new data".  It only means "Broken connection" when
select() indicates that the socket should be read from.

This should do the trick.

Eric

I'm a bit confused about using mmap - it's not clear what "fd"
in the man page refers to:


     caddr_t mmap(addr, len, prot, flags, fd, off)
     caddr_t addr;
     size_t len;
     int prot, flags, fd;
     off_t off;

DESCRIPTION
     mmap() establishes a mapping between the  process's  address
     space  at  an  address pa for len bytes to the memory object
     represented by fd at off for len bytes.  

What is this memory object pointed to by fd, and how do I define
fd?   I want to map some pages created by valloc() to another
virtual address space.  Can I use mmap() for this purpose?

	When I turn on my PC I go to MS-Kermit mode to type the phone number

	If your problem is only about having a non-blocking "accept()", then
you mark the socket as non-blocking. If you then try accept() , you will see
that accept will accept the connection, if there is a pending connection request.
On the other hand if no pending connections are there, then accept 
will return immediately with an error (I think EWOULDBLOCK).
You can use fcntl (O_NDELAY or O_NONBLOCK) for the server socket to get this
feature.

With current technology, the only reasonable way to homebrew a UNIX box is by
leveraging the ISA/EISA 80[34]86 standard.  I wish it were otherwise, but the
68000 family lost its war nearly a decade ago now and no RISC chip yet commands
anything like the breadth of support the Intel family does.

Go pull my latest clone-hardware guide for UNIX buyers out of the news.answers
archive; keyword "pc-unix".  It will tell you most of what you need to know;
also, why the UNIX-workstation market as we have known it is living on
borrowed time...
