    I'm not sure what the comment about HD partioning has to do with anything.

I'm looking for a way to consolidate our dial-out modems.

Currently they are spread out over several machines, and it's becoming a
pain.

It would be nice to have a box on the net that someone could telnet to
(without logging in), have it automatically decide which modem is free, 
ask what # to dial, and make the final connection.

I've seen dedicated hardware for this, anything similar for Linux?

I happen to work on the Sun compiler, so I just can't resist posting this (I know
this is a Linux newsgroup, and I feel bad having to do this). In general, when
talking about compilers, please include the version number of the compiler (for the
Sun compiler, use "cc -V"), the optimization level (there are a *lot* of optimizations
enabled at higher opt levels which are not included at lower opt levels), the platform
you were compiling on (SS-2, SS-10, etc). Another sweeping comment is that there are a
lot of hidden things buried in your source code which may inhibit optimization, and
when looking at the .s file it may seem that the compiler is brain dead (in certain cases
it is, but for the most part, they seem to do a pretty good job). Compilers are getting
very tricky nowadays, and you have to look real hard before jumping to any conclusions.

To get good performance out of your RISC box, it is actually quite important to optimize
the code properly. All of the RISC vendors (HP, IBM, Sun, etc) have pumped a lot of
money into building good compilers. When new chips are announced, there is generally a
compiler that goes with that release that optimizes code for that chip. I therefore
disagree with your comment about "some features were being neglected".

Linux plug : I am an absolute fan of this operating system. The installation was a dream
(thanks to whoever put Slackware 1.1.2 together !), and the whole system is just incredibly
stable. I was even able to get networking up and running within minutes. I hope we see
a port to SPARC sometime.

Subject: Experience with PAS16 MediaVision kit
Date: Wed, 6 Jul 1994 19:10:44 GMT

I just bought a MediaVision kit that includes the PAS16 soundcard and
a SCSI (purports to be II) CD-ROM drive.  Attempting to boot with
Linux caused two problems.  Since I feel this is a very cheap and very
useful kit for Linux users, others will probably be tempted to buy it.
The good news is that it works with Linux, but not with the standard
distributed kernels.  The problems and the fixes are:

1) The newer PAS cards do not have a jumper to set IRQ.  It's
programmable.  The Linux SCSI driver does an autoprobe for the IRQ by
default.  Make sure to add a #define PAS16_OVERRIDE {{0x388, 10}} to
the file linux/drivers/scsi/pas16.c.  This will tell the device driver
to assign irq 10 to the PAS16 card at address 0x388.  You can also use
the Lilo command line, but I'd rather have it in the kernel.

2) The CD-ROM drive that comes with the kit is not terminated.  ARGGHH!
A total violation of the SCSI standard.  A different cable might help.
Anyway, the symptom with Linux is that the kernel goes into an infinite
loop while booting as it searches for devices on the SCSI bus beyond
the first one.  Since it ain't terminated, there's no notification that
there isn't anything else out there.

  My fix for this (and it's a kludge) was to not search beyond the
first lun for scsi devices (since the only scsi device I have is this
cdrom).  I changed the loop specification in file linux/drivers/scsi/scsi.c
in routine scan_scsis(), where it's searching for all possible luns (0-7)
on a scsi host.  Other, cleaner, solutions are possible (ie. only limit
the loop if this is a PAS16 card, determined from the INQUIRY result).

  The best fix would be to terminate the SCSI bus.  The cable does not
allow daisy-chaining, so I can't put a terminator at the end.  I don't
actually know a lot of details about SCSI hardware, so if anyone figures
out how to terminate the SCSI bus, please tell me.

Specifically, the directory for the F series on ftp.cdrom.com is

Furthermore, TSX-11.MIT.EDU is not properly mirroring ftp.cdrom.com.

Depends on what you mean be `everything'.  I can boot a fully
functional kernel containing almost all of the common Linux utilities.
That doesn't include X, emacs or groff, but does include ksh, perl,

Subject: why won't old socket connections disappear?
Date: 6 Jul 1994 01:13:36 -0700

I am trying to get a reliable, reusable socket connection between two
internet machines. and I'm having some trouble

one machine (to be called trapper from here on) is to simply create and
bind a socket and wait for accept() to accept a connection.  when that
connection is established it is to write 40Kbytes to the machine on the
other end over that socket and then simply shut down the socket file
descriptor returned by accept and then go back to the accept() location and
wait for another accept().  so its whole purpose is to wait for other
machines to attempt a connect and when they do give them a 40Kbyte file and
wait for more machines.

the other machine (to be called phakt from here on) is a machine that is
testing the reliablity of our socket connection.  in that it is trying to
connect as many times as it possibly can to trapper.

i.e. it creates (but does not bind) a socket and then tries to connect to
trapper, get the 40Kbyte file and then close and destroy it's own socket
and do this whole procedure again again.  (always creating a new socket).

here's the code for trapper (the listener)

listen()
{
  int sockfd,len;
  struct sockaddr_in addr;
  int portnum = 27650;
  sockfd = socket(AF_INET,SOCK_STREAM,0);
  addr.sin_family = AF_INET;
  addr.sin_addr.s_addr = INADDR_ANY;
  addr.sin_port = htons(portnum);
  bind(sockfd,(struct sockaddr *)&addr,sizeof(addr));
  listen(sockfd,1);
  while (1)
    {
      newsockfd = accept(sockfd,(struct sockaddr *)&addr,&len);
      Write40Kfile(newsockfd);  /* write 40Kb to the file descriptor */
      shutdown(newsockfd,2);
      close(newsockfd);
    }
}

and the code for phakt which attempts multiple connections is:

call()
{
  int sockfd;
  int portnum = 27650;
  struct sockaddr_in addr;
  struct hostent *hp;

  while (1)
   {
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    addr.sin_family = AF_INET;
    addr.snin_port = htons(port);
    addr.sin_addr.s_addr=inet_addr("128.125.4.25"); /* trapper's ip address */
    connect(sockfd, &addr, sizeof(addr));
    Read40KbFile(sockfd);
    shutdown(sockfd,2);
    close(sockfd);
   }
}

please forgive the liberty I took in removing error trapping statements
and generating some psuedo-code calls.  the socket creation and connection
is happy and is having no problems however my problem is that it seems
sockets aren't being closed properly.  for instance when I run listen() on
trapper and call() on phakt after a few minutes trapper simply locks up and
I have to reboot it.  I couldn't figure out why but I noticed that when I
do a 'netstat' when the procedures above are running I get this:

Active UNIX domain sockets

====== END netstat output ======

so as ou can see I have tons of connections hanging around waiting for
something to happen.  If I kill listen() and call() then these connection
hang around for about another minute or so and then they finally
dissappear.  I have tried setting SO_LINGER to {0,0} and SO_REUSEADDR to 1
but this didn't have any affect and quite frankly I don't know what they
do, I just tried them because they were in another socket using program I
got from somewhere else. (netrek)

I figure that by allowing call() to run unchecked I exceeded some sort of
limited resource and this is what hung trapper.

Am I missing something about how to close down internet socket connections
gracefully? or am I doing something else entirely wrong.

I also apologize for this posting being so long, I just wanted to make sure
you socket wizards out there had some idea of just what I was doing.
if you need the actual original source files for the call() and listen()
program I'ld be glad to send them to you.

Please help me if you can I would really appreciate it!!!

Date: 6 Jul 1994 10:58:04 +0300

I discuss two problems : 1. Linux vs. OS2  and 2. Linux download costs.

1. A small company where one 386sx33 4MB is working with 4 people hot 14
hours per day under DOS and WP51 editing mostly plain texts with average size
20 pages, yet have 10MB of textbase, texts are mostly law documents - need
little but concrete formatting.once per day graphic preview is needed.Company
is qoing to move to two differrent locations,
with the only possible link 9600 Kb line between.Now has serious lack of
computer time( keyboard time).Would need 3..4 workplaces if growing.

*Another DOS machine would go - but whats a pity to see $ being idle 95% and
networking like frontdoor is not the standard,like pcslip is not complete, 
little money little headage, little outcome.
*Take OS2 - I have seen and tryed it for 1 day - mail, multiuser, remote
mount over dialup line ? cost of soft? Training costs ? Headage cost? makes
too much together for 2 workplaces .
*Take Linux - take 2 vt220 ant 2 modems and have 4 workplaces. The only why
to refuse is good editor. moveing from capability of WP to emacs or whatever
user gets stuck anyway (with 20 pages of text inc O~ A" etc). my Headage costs ?
 user headage studing new costs ? 
*the DOS if they want to go easily or Linux if they want to have a wide way.
*the OS if they want to have wide costy way.

with the same lightness OS2 fans could put up company with OS2 as most
optimal OS (for example : a trustable ( nonlocking) multiprocess workplaces
with extensive use of graphics and specialized database programs not available
under Linux)


2.
I don't know the US-like poilitics about billing ftp. We have slow link from
estonia(1.5M pop,a 64Kb, daytime average ftp 1.5 KB/s) our local netmanagers have
solved the problem with Linux by setting up local ftp server for Linux and
Gnu and other high-volume free  stuff.
        That's why I am confused reading about Linux download costs. If some
Linux-fans reading it - why have'nt You done this in our times when prices
on HD dropping dramatically.Linux-virus spreads (here)mostly from mouth-mouth
connection, less people get the knowledge from journals and netnews.If You
are real fans, there is no problem makeing 1 Linux support site for area of
500 000 people and letting it know (in faqs or in some www server).
        BTW where is www or gopher server for Linux, for its >10^5 users group?
Does it have online database you can search trough old news and other papers
systematically to get answer for Your problem with minimum time?
if it exists, let me know please.If it does not, it is likely time to have
it. my newsreader is bored of questions like VC switching.

Arguing is useful for something to get done, oterwise it is better to stand
away from computer, run 10 times around the house and get nice sleep.hair is
growing faster and children will be more healty.

I just bought one.  The price was 438, including the VLD motherboard.
It is a new chip, dated 04/1994. Runs fine, but quite hot :)

I don't use SCSI, but so far I have had no problems under heavy load.

I wonder if otther AMD486DX2/66 users could give me what speed they get
under Norton Utilities System Info. Mine has 72 persistently, but
when I start up the CPU benchmark it jumps up to over a 100. Any idea
why that happens?
