There is no limit to the NUMBER of files.  There seems
to be a very real limit to the ability of the shell to
expand humonguous file name wild cards.  For example
under 3.2v2 and before, >1500 files in my Bnews
directories would break simple commands like: ls -al

Under 3.2v4, SCO added EAFS (Enhanced Acer Fast file System)
which includes support for 256 character file names.  I would
have expected that the file name expansion buffers be increased
to handle the potential increase.  Not this time.

It's the SIZE of the directory entries that breaks the shell
expansion, and not the number of files.  For example:
	cd /usr/spool/news/comp/unix/sysv386
	ls *
works correctly with 3100 files in the directory.  However:
	cd /
	ls /usr/spool/news/comp/unix/sysv386/*
bombs with:
	ksh: /bin/ls: arg list too long
because the wild card expansion overflows the shells buffer.
Note: all the filenames are 5 characters.

>Jean-Pierre Radley   Unix in NYC   jpr@jpr.com   jpradley!jpr   CIS: 72160,1341

I have several reasons (besides being lazy, disorganized, and sloppy).
1.  Bnews generates huge numbers of files.
2.  I have several "info-servers" running that pass documents
around on demand.  I could force the user to deal with subdirectories,
but for the level of expertise involved, a simple filename is
all I can expect them to get correct.  Therefore all my info-server
files are in one big directory.
3.  Fonts.  Most DTP programs are too brain dead to search for
fonts in various directories and expect them all to be in one
directory.  Put screen and printer fonts in one directory and
I can easily hit 1000 files.

As I blunder through Unixland, I keep running into other
limits.  There apparently is a 128 character limit to the size
of a uux command line.  This broke a local mailing list.  The find
command appears to break for wild card expansions > 2048 characters.
I'm sure there are others.  Does anyone have a list of buffer
sizes and command line limits?

I was kidding and not kidding.  Most of my clients do have modems, but
I don't make it mandatory  (only thing that's close to mandatory is CTAR)
and small Xenix systems seem to be the hardest sell for modems.

And, frankly, I do very little modem work.  I prefer to be on site 
(I like people *much* more than I like computers) and in the case of
a patch to /xenix (which is what this was) there is no way I am going to 
do it over the phone unless I've got somebody I can really trust at the 
other end :-)

But even for the simple stuff, I like to work at the site.  Having 
multiscreens, being able to hear and smell the equipment, getting to
see what users are *really* doing against what they say they did, it all
just makes me feel more comfortable. Fortunately, almost all my clients 
are within an hour's drive, and even the worst are only three hours, 
so this works for me.  Though it's obvious I could make more money
if I sat here in my office.  Wouldn't like it, though.

But I have friends who do exactly the opposite:  they *won't* go on-site,
and modems are mandatory for their clients.

Different strokes.

Summary: has anybody done this? Sources?

We plan to install an ODT system that will be connected to several remote 
buildings either to other ODT boxes, PCs or terminals. Could be either serial 
or ethernet.

This is in Florida lightening country and previous installations in the area 
have always resulted in painful lessons about surges, blowouts etc. 

Has anybody learned to over come this problem with fiberoptics cabling? 
Products?  Sources?  Can this be done by an inexperienced installer (as far as
fiber is concerned) We would really like to have some kind of a mux box that 
would be connected via one fiber cable but have several more common serial or 
ethernet lines at each end.

Any and all suggestions and recommendations would be appreciated.

Perhaps the dialer program is changing the settings on your modem
without you knowing it.  Command mode echo needs to be off.

Well, I posted a similar message a few months back, but regarding a Specialix

Try using XC to do cu's job. If you don't have xc, I can mail you the source

There is in fact such a limit; but it is not a limit on the number of
files in a directory.  It's a limit (of 1000) on the link count of an
inode.  I don't know what purpose it serves -- perhaps it prevents some
of the filesystem utilities (specifically fsck) from breaking.  It is
still present in 3.2v4.  Brian probably ran into this limit by trying to
create more than 1000 subdirectories in a directory.  Each subdirectory
has a ".." link to its parent, which counts in the parent's link count.

Brian, to avoid this limit *and* to improve performance, you should come
up with some sort of two-tiered directory approach.  If you currently
have directories named after a custom, instead name them
.../C/Customer1, using the customer's first initial to break them up
into smaller groups.  This is the approach used by terminfo and SCO's C2
TCB directories.

The reason for wanting to submit the C-News in a custom installable format
is for those individuals who don't have the luxury of a C Compiler. I get
about 5 requests a week for the C-News that is installable through custom.
I tried for three weeks to get the C-News from utzoo to compile under
SCO Unix 3.2.4.

Thanks, but I want a proper highlighted menu cursor, error checking,

Hi,

since running ODT2.0 on my system I have trouble with dial-in's.
The Modems connect successfull and login: is prompted.
login: username <CR> is ok and also Password: appears. After that
nothing is going on. A "ps -ef" show "/bin/login username" .

Does anybody know why /bin/login hangs, if it was started from
tty2A ? I have no idea :(  

Supplementary I should say that dial-out's running well without any
problems. So a hardware problem can be excluded.

thx

Are you specifying the port on the uugetty command line as
"/dev/ttyA12", or just "ttyA12"?  You *must* use the latter in order
for the bidirectional tty support to work, because uugetty looks for
the port name it was given on the command line in the Devices file to
find out how to initialize the modem for dialin.  So, if you are using
/dev/ttyA12 instead of ttyA12, uugetty will look for a "/dev/ttyA12"
entry in Devices (and, of course, not find it).

I dont' think it's silly for this reason.  

I want to have manual control over the way the rest of the disk is
handled.  I also have found that at times, if you tell it you want a
filesystem, it will give you minimum/maximum values to choose for your
initial filesystem which don't always coincide with my idea of how I
want it laid out.

If mkdev fs were to be run for the /u, I'd surely want the script to
continue to ask for block amount/sizes on a system by system basis
until I had used up all the available space.

If it were fixed to do the latter (as some other Unix systems I have
used), I'd go along with it.  But just to blindly make the rest /dev/u
if you request a second system would not be the way to do it, IMO.

Hi, people of netland.

I need some advice.
As the subject says, I have to program an rlogin-client with some special
kind of magic ( that's the reason to reimplement it ). But how does
rlogin work ?
My idea:

- do some terminal-control ( raw-mode )

- get a socket connection to rlogin server

- fork, to get a reader and a writer process
  reader: read from stdio and write to socket
  writer: read from socket and write to stdout

- but now: what shall I do now ? What kind of protocol/hanshake does the
  server expect ?

Any help appreciated. Ah, I forgot, It should work on SCO-Unix and SCO-Xenix.
The rlogin-server resides on a non-unix-system, which supports rlogin, but
expect a special terminal-type ( which I have to emulate ) in my client.

I am getting a "Hangup : <pid>" message on my screen.  I am sure that a
process which I wrote is causing it.  The process dups stdin to /dev/null,
and setpgrp()'s after forking off.

This process at some time then, calls system() to exec a command at the sh.

How do I verify the Hangups are coming from my process or the one that gets
exec'd??  Obviously the pid number is no good, because at that point the 
process is dead.

The default distribution of c-news compiles just fine for SCO without
any special modifications to the source.

Why have a "special" version for SCO? Its not needed.
