You are using dosemu version that is 2 years old and
is unsupported for ages. Unless you upgrade, you are
on your own with your problems.
To make you more motivated, I can note that the newer
dosemus are trying much harder to release as many CPU
power as possible to the OS.

Re: Resources Eating?

[Guillermo Gomez]

Got the message, please point me out where's the bin package like the
one i use to work with (i'll chek the website anyway).

I downloaded the latest source code and compiled it. Great but my
problem now moves to the fact that any single client needs a separate
autoexec.bat as well as separate "login" profile.

What i'm doing is:

1.- Client telnet the linux box
2.- Client logs in with bash shell
3.- .bash_profile takes care of auto-launching the dosemu
4.- autoexec.bat takes cares of auto-launching the app
5.- As the app quits, the shell autoquits just after
	(no open shell for the user)

How u do suggest i could accomplish the same effect with a "system" wide
installation like the one resulted from compiling from source code?

Just as i reminder, i did tried the latest source code of DOSEMU and
FreeDOS (bin.ziped file) and the app program simply does not work (i
must use MS DOS).

If i can have a bin package like the old one i could just do the same
but with the newer version and then i might have a chance.

Thanks

Guillermo

what if they hit CRTL-C ? :)  you should be able to set their shell to 
dosemu.bin, and see if that works ok.  Can you make a seperate login for 
each different instance of dosemu, each with their own copy of dosemu, 
that way there is no need for a seperate autoexec.bat.  You must have a 
copy of real MSDOS don't you?

Re: Resources Eating?

[Guillermo Gomez]

Well i'll check out what happens if they hit Ctrl-C, as far as i
remember is just does nothing (don't gives back the shell).

The need for separate autoexec.bat is "customisation", all clients needs
a different paths and this is how the app works in order to account
users: must have separate autoexec.bat :(

Anyway the dosemu as shell login is a geat idea, i'll try it but there
is a little requirement for that:

Multiple login not allowed !!!

This is an app requirement from the app (again).

I'm taking care of this in .bash_profile (or .bashrc).

How could we avoid multiple login using dosemu as login shell?

I guess there must something in a lower level regarding the "login"
process.

There is a script there dist/mkbindist. I don't
know why it is still not executed automatically by
"make", which will make it more usefull, but you can
use it manually.

Re: Resources Eating?

[Guillermo Gomez]

Hi 

Sorry for the stupid question, the bins were there just for me to
download them...

I already made the same procedure as i did with the previous version i
used.

1.- mkdir mydos
2.- copy both zipped files into mydos (dosemu/freedos)
3.- unzipped them
4.- i substitute freedos content with MS DOS (from W98) bin files
5.- Got the readlink compiled to make the dosemu script work
6.- Got the message running with the new version as exactly before
	Each user with a copy of dosemu and dos.
	Each one with an autoexec.bat and so on
GOOD NEWS
	The application behaves better with this version
	Now with the application "doing nothing", the CPU is sleeping :)
	When the app actually does something, the CPU usage jumps
	Summary: the CPU is used when the app requires it

GREAT but..... there's always a but....

Remember my problem was the passthrough printig, well i can't make it
work now :/

With the previous version, the modified section at global.conf as:

if (strlen($_printer))
      foreach $xxx ($LIST_DELIM, $_printer)
        ## $xxx = "' %s '";
        ## printer { options "' %s '" command "cat - | ansiprint "  
        printer { options '%s' command 'vtprint -fq' }
      done
endif

made the trick to return the print to the stdout filtered through the
vtprint program.

Now i made the same changes to my global.conf but i does not follow my
directions, it alwasy tries to do lp and reports the local lpd daemon
not responding (there's no printer configured).

Any suggestion to make this work?

Hoe the timeout parameter in the print command could be related to my
issue with large documents?

Thanks

Guillermo

Re: Resources Eating?

[Guillermo Gomez]

Well i found the problem is that the global.conf is "builtin" is taken
precdence and my modified global.conf is not doing anything.

I'm trying to use the -F option with no luck..How can i dump the
"built-in" global.conf to tweak it using option -F.

My installation is working ok without the -F option.

Presently only by editing etc/global.conf in the source code and
recompiling. dosemu.bin in the bindist can be replaced by the one you
obtain that way.

> My installation is working ok without the -F option.

it's on my list to fix for 1.2.0. -F should work. The problem is here:

In file included from
dosemu/dosemu-cvs/dosemu-1.1.99.1/etc/global.conf:212
Error in : (line 212) parse error
Error in : (line 556) parse error
Error in : (line 556) expected 'emulated' or 'native'
3 error(s) detected while parsing the configuration-file

by the way, because your problem came up in different variations before
the CVS version (and 1.2.0-final when released) allow you to do what you
want in dosemu.conf or ~/.dosemurc:

# list of (/etc/printcap) printer names to appear as LPT1, LPT2, LPT3
# (not all are needed, empty for none). Default: "lp"

# $_printer = "lp"

# Print command to use. Default: "lpr", for "lpr -P printername".
# Sometimes (with CUPS) "lpr -l" is necessary.

# $_printer_command = "lpr"

Re: Resources Eating?

Thanks Bart

I was killing myself trying to make it work...i saw many times the
'emulated' or 'native' message :-D

I'll try further with source code and hope to figure this out asap.

Re: Resources Eating?

[Brett I. Holcomb]

Just to make sure I understand this:

1.  /etc/global.conf
A. Don't mess with /etc/global.conf because you can break things.
B.  I found my install left the /etc/global.conf.example and did not create a 
/etc/global.conf.  Would that have hurt me or is what's in the example file 
built into the dosemu.bin.

2.  /etc/dosemu.conf and /etc/dosemu.users is what we work with to change 
global settings - correct?

3.  ~/.dosemurc is used for users who want to set up their own special 
settings  - correct?

Thank you.

yes. its main job is to parse dosemu.conf. However every once in a while
we encounter situations that are impossible to configure with dosemu.conf.

yes. These files can also live in /etc/dosemu.

dosemu.users is optional. Only if certain users are allowed to use direct
hardware i/o ($_ports and so on) through a suid-root dosemu.bin or dosemu
-s with sudo, you'll need to edit it. As far as such access is
concerned, only console graphics works with a privileged dosemu by
default.

dosemu.conf lives in the same directory as dosemu.users.

yes. Just like /etc/profile vs. /etc/.profile. Some settings in .dosemurc
are ignored for security reasons.

Re: Resources Eating?

[Guillermo Gomez]

Hi

I compiled from source including global.conf modified as...

...

if (strlen($_printer))
    foreach $xxx ($LIST_DELIM, $_printer)
##   $xxx = "'-P", $xxx, "'";
##   printer { options $$xxx  command "lpr"  timeout $_printer_timeout }
     printer { options '%s' command 'vtprint -fq' }
   done
endif

...

But vtprint is reporting the following message

vtprint: Couldn't open %s for reading.-

What i'm doing wrong now?

remove the %s. The command should read from a pipe now, instead of
printing a temporary file, and that's why the %s is obsolete.

Re: Resources Eating?

[Guillermo Gomez]

Well in my case is not a problem of speed or logic.

More than 10 sessions works, the big issue is printing (passthrough), it
works with "small" documents (up to 4 pages).

So i really can't tell if it's just because the resourses eating or a
networking problem.

Today i tested again (passthrough) and the nice 0 level of the telnet
server did not make any difference.

I included today the flag NO_DELAY for further testing.

The interactivity with the application is ok. What i see is the
developer of the application (or the compiler BC) using a stupid loop
consuming all the CPU cycles just for refreshing the display. However
the logic of the program is not being affected, is the network
transmission, it just stops, could that be a consequence of the lack of
CPU cycles?

Resources Eating?

[Guillermo Gomez]

Hi all

I'm using dosemu to provide remote sessions (telnet) to certain dos
applicattion running in my Linux box.

Each Linux client has a binary dosemu installation in the server (what i
need is separate autoexec.bat for each client) plus a Windows98 DOS
(minnimu).

FreeDOS does not work witht this application written in QBasic (invalid
opcode messages). The application is also based in Novell betrieve
register mannager (sort of data base manager).

The point is that the "program" is eating all the CPU. When one session
is working everything looks fine and when more clients get's connected
the CPU is splitted more or less with equals shares:

Examples:

1 clients --> 90% CPU

2 clients --> +/- 45% each 

The problem is that the server machine start to behave badly (stop
sending data through the telnet server) for no apparent reason in
certain situations.

I already tried the hog thing, it's in 1 (default) so i guess i can't
lower it anymore :(

The last thing i tried was to nice the telnet server to 0 just to see if
that helps.

Running the program is no the big thing, the problem arises when we
print using the passhrough printng features of our telnet client (Anzio
Lite).

I sniffed the traffic and yes, the server jus stop sending data.
Somo simillar sympton happens when starting "btrieve". The screen
freezes but at this point if we press Esc, then the application keeps
going as nothing were happen.

Any help would be appreciate it.
