Subject: Re: text: table full
This is a common problem. We have all our systems modified with a larger
text table.
The problem is not just lots of processes -- the problem is lots of
*different* code (text) files. (Text is generally sharable between
processes.)
Sun's algorithm for determining the size of the kernel's text table is
inadequate for many uses of the machine. As has been mentioned here
before, increasing MAXUSERS is not the best solution as that affects
things which do not need to be changed.
Go into /sys/conf and modify param.c. The algorithm to change is "ntext".
(We double the default size of the text table and no longer have
problems.) Config and make -- all new kernels will have the increased text
table.
To modify an existing kernel, do the following:
# adb -w vmunix
ntext?W 0tDDD (Where DDD is the decimal size of the new table)
^D
# reboot
I recommend you do NOT make the above patch to a running kernel!
Thanks...

Just to give credit where credit is due, the dump that Sun is using is
based on the 4.3BSD dump which uses seperate disk readers and tape writers
to get the speed. This enhanced dump was a rewrite done by Don Speck of
Caltech who has tweeked and hacked on dump in every conceivable way to get
as much speed out as possible.

Subject: Re: DNI Protocol Error question
The same thing (protocol error) happens when you try to 'dnalogin' to an
ULTRIX (at least v2.2) machine and vice versa.
I think this is caused by some undocumented protocol behaviour (btw: is
there any official CTERM documentation available?). Since DEC's protocol
may be considered correct (it's *DEC*net we're talking about :-) ) and
everything works fine between ULTRIX and VMS machines, Sun should fix that
problem.

I'm just putting the finishing touches on a similar configuration. We
have a lab with a central machine serving /usr/spool/mail to several
clients (all systems run SunOS 3.5). The main hack to make this work is
that sendmail.cf on any client forwards ALL mail to the server, even
(especially!) mail that appears to be addressed to the local machine or to
another client machine. I did this with a very few changes to Sun's
subsidiary.cf template, so that any calls to the local mailer are
pre-empted and re-directed over the net to the server machine, as in:
# Instead of calling local mailer, call gateway mailer and pass to
# gateway machine:
#R$+ $#local $:$1 local names
R$+ $#$M $@$R $:$1 local names
I also commented out the lines that attempted to do an SMTP connect to
systems found in either /etc/hosts or the equivalent YP database.
The 'server' sendmail.cf was changed so that whenever it sees mail
addressed to a machine in its list of clients, it will instead deliver it
locally.
Some other touches included modifying the 'From:' address; the net result
(no pun intended) is that the server/clients combination looks to the
world like one machine named 'afws.csun.edu' (for Advanced Function
WorkStations). Users can read their mail from any of the client machines,
and mail they send from any client appears to be from a machine named
'afws.' I'm only a sendmail hacker by necessity, not by preference, so
what I've done is probably pretty sloppy, but it works. It's not entirely
done yet, but it's close enough to use in production and fine-tune as we
go along.
Making sendmail setgid 'mail' with /usr/spool/mail/* writable by group
'mail' may appear to be a simpler approach, but I think there are some
problems there, mostly to do with the fact that on BSD systems only root
can set owner on files.

readers that the "Sun User Group" is not the same as "Sun Microsystems".
Please do not interpret this as a commercial announcement posted by Sun,
because it isn't. --wnl ]]
Information and news. Points of view. It's time to come and "Feel the
Heat" at the biggest gathering of Sun users ever, and the best platform

year the conference will focus on both business and technical issues in
the information processing environment.
** Snapshot: Sun and SUG in December
Hear about Sun's role in operating systems standards: OSF, System V,
SunOS, POSIX. Learn how Sun users solve heterogeneous networking problems
with Suns, PCs, Macs and supercomputers. Explore the worlds of publishing
and animation on the desktop. Understand how workstations help in fighting
the cancer battle or managing a front office. Discuss current technical
issues: X.11/NeWS, PHIGS and PEX, networking how-to's, Folio font scaling,
and more. Participate in business issues: service, support, futures and
standards. Hear Sun executives including Scott McNealy, Bernard LaCroute,
and Bill Joy talk about the state of the information processing
environment. It's information exchange at its best! A total of 88
sessions, plus special panels, keynotes, and new pre-conference tutorials
will make for a full agenda.
** What is it?
It's the 1988 Conference and Exhibit sponsored by the Sun User Group
(SUG). SUG is an organization of business and technical professionals
interested in the products, services, and strategies of Sun Microsystems,
Inc. Members and non-member of SUG are invited. The conference will focus
on both technical and business issues in the workstation environment.
** When is it?
It takes place December 4, 5, 6, and 7. A full agenda will be available at

Subject: HELP...HP laserjet printing graphics on Unix
I have been trying to get my HP laserjet+ to print raster graphics for
over a week now and have not had much sucess. This printer was previously
connected to a 3Com network and was able to print raster graphics with no
problem. We have removed the 3Com network now, and I moved all the
printers over to our Sun server and our VAX 11/750. The two areas that
seem to be giving me problems are that the HP wants 8 data bits with one
stop and one start bit, and also needs to use hardware handshaking. Can
anyone shed any light on either of these subjects? I realize this may be
old stuff, or else trivial to many, but I just can't seem to make it work.
:-( Please help if you can. Also, send me mail unless posting is
appropriate.

Subject: Postscript to Impress filter?
In the last year, we have switched from relying on an Ultrix microVax II
to a Sun network. We are very happy with the Sun workstations, but the
change to postscript that resulted has given us a problem. What do we do
with our Imagen laser printer, which we also like; it has a number of
modes including IMPRESS, TEk4010, ... but doesn't understand postscript.
Hardware conversion is not practical. The local QMS (nee Imagen) district
manager told me that they are working on a software solution to our
problem, a postscript to impress filter, but he didn't expect it until
next year. He also implied that others were working on one.
Well, this sounds exactly like what we are looking for, but I'm having
trouble getting anything definitive from QMS; I gather their merger with
Imagen has them occupied. So my question for the net is - does anyone
know of such a filter for Suns , PD or commerical, and if so, where can I
acquire one?
Thank you for your support.
[[ I think this would be better placed in "laser-lovers". Are you aware
of the "UltraScript" language that is now available for Imagen printers?
It's supposed to be "just like PostScript", although it is rather
expensive. --wnl ]]
