A program like Exceed is an X server, not an X client. It serves
display/keyboard/mouse resources to clients (like netscape) that need
such stuff.
X clients are told where the server they're supposed to connect to for
display via the "-display" option, or by setting an environment variable,
"DISPLAY". Eg. on the remote client, you might type:
netscape -display <hostname>:0
or you could type:
export DISPLAY=<hostname>:0 ; netscape
The X server must be authorized to allow connections from clients
running on <hostname>. This can be done by executing:
xhost +<hostname>
(I don't remember exactly how Exceed does this. They have some setup
tools for such. On a normal Xserver, you just open a window and type it
in.)
The daemons which service rsh and rexec are in.rshd and rexecd. But these
are started by inetd, so you won't see them running unless a connection is
already made. Enabling the connections is beyond the scope of a newsgroup
reply... read up the man pages and networking HOWTOs.
But, in general, it's probably easier (and definitely safer) to use
telnet to start up your clients on the remore machine, as rsh and rexec
are security risks if your network leaves the room the 2 machines are in.
If there's danger of sniffers, you can do this over ssh as well.
If you have a display manager (graphical login) running on the machine
you want to connect to for running the clients, you can do a query to it,
and it will pop a graphical login screen on your local Xserver. From a
unix machine to another unix machine, you could:
X -query <hostname>
and you'd get the graphical login. Then you don't have to worry about the
rest of the above. (I believe Exceed has a query mechanism as well.)

Reply-To: "E.M. Stegehuis \(Marcel\)" <[EMAIL PROTECTED]>
A while ago we 'upgraded' from RedHat6.2 to RedHat7.0. Since than we are not
able anymore to use rexec nor rsh to get an xterm on an other machine.
With ntsysv I ensured that rexecd and rshd are on. The
/etc/xinit.d/rexec/rsh files show the service to be available (disable=no).
According to the message on the RedHat site I commented the
auth required /lib/security/pam_nologin.so
line in /etc/pam.d/rexec.
Stil I get a connection closed.
My /var/log/secure file mentioned a xinetd[PID XXX]: START: exec pid=xxxx
from xxx.yyy.zzz.aaa
Does anyone recognize the problem and knows a solution.

[It makes it easier to follow the conversation if you put your new text
*after* the text you are quoting and snip unnecessary bits.]
ipchains typically resides in /sbin because you need to be root to use
it and it may well be required early in the system boot sequence.

Any distro should be fine. They're mostly the same when you strip away
the fancy goods.
Try Slackware, or another small one.

Just as a reply to many of the posts about
Linuxgruven. I have gone through the interview
process and had my doubts at the start as well. I
passed their initial interview and test. The
interviewer offered me a seat in training. I was
given an offer of employment after paying the
fees for the 80 hours of class.
The training was good quality and class taught me
alot about the Linux operating system and the
many things that can be done with it.
(Samba,NFS,Apache)
I am currently in the process of taking tha SAIR
exams and looking to be hired on. I did see
several new faces, people being hired on that
passed the exams.
As with anything their will be people who doubt
the validity of this thing. To go through the
process and finish the class gives me a whole
different perspective that many people will never
see about Linuxgruven. The company will be the
industry leader in Linux service and support. I
believe this because there is no other company
out there able to offer the volume and quality of
support that is needed.
I did not have the LCA certification when I
interviewed, but they must have seen something in
me to offer me a position with their company
after completing the exams. I took the training
to speed my learning process.
Not many companies offer the Linux training.
Do the reasearch for yourself. If you like Linux
or want a career in the Linux community this IS a
GREAT option!

My car stereo runs Linux - the designers of this
(http://www.empeg.com) use the Debian distribution and tools to
create the environment. It has 1MB of flash memory which I believe
holds the kernel, it does have a hard-drive to store all the
music, the other OS files and the music player app. - but I
suspect it uses significantly less than 64MB of disc space for the
OS as it's a very stripped out version of Linux. You (cross)
compile stuff on another Linux host and simply transfer the files
over.

Can't 'find' the ipchains command. Using Kernel 2.0.34C53_SK on Cobalt Linux
release 4.0. Could another command be used to specify tcp session timeout?
If so, I'd be more interested in where I would specify this
(etc/rc.d/rc.local ?).

Thanks. That's it. I actually used this parameter, but misspelled it as
hdb instead of hdc (where my cdrom resides). That's why id didn't work
for me the first time. :)

It has, so I didn't need to recompile. I was just wondering about all
the other modules mentioned in the HOWTO and since I didn't recognize my
typo at first time, I was a bit confused about all this modules.

No Problem. :) I now access it as an scsi drive, but since that is
transparent I don't care about it too much. :)

You could also install beav, which is a much hacked version of
microEmacs. It will edit binary files using whatever representation
suits the task (hex, short int, long int,...).
Unlike some binary editors I've used, beav doesn't commit the changes
until you save the file.

Subject: passing parameters to printer (ghostscript)
Date: 10 Jan 2001 11:18:50 GMT
I compiled ghostscript 6.50 under redhat 6.1 to access my
HP4500 ColorLaserjet printer (pxlcolor device).
I need to pass
"statusdict begin false setduplexmode 0 setpapertray end"
to ghostscript not knowing whether GS would translate that
to the correct PCL sequences anyway.
Any ideas how to access this printer optimally?
I found that printing direct postscript to the printer
doesn't give good results WRT colors. Printing from Windows 2000
gives the best results and Windows has some color correction
built in the native Windows GDI driver.
The other idea was to smbprint from unix to a Windows printer
but thinking of it I came to the conclusion that this wouldn't work either
because sending a Postscript file to a shared printer under Windows,
does that work? I suspect the driver would just print
the postscript text which is not what I want.

Ah. ipchains is a kernel 2.2 thing. As you're using kernel 2.0 you
need ipfwadm. See "man ipfwadm".

Yes, that would probably be a good place.

AFAIK both can be compiled as modules, so the kernel bloating is not
really an issue. With the kernel module loading the modules will only be
loaded as long as they are needed.
I'd go for USB.

On my system, I have the following lines in some makefiles (among others
that I will not bore you with):
MACHINE_TYPE = -mcpu=i686 -march=i686
OPT_LEVEL = -O2
CXX_FLAGS = ${DEBUG_FLAG} ${MACHINE_TYPE} ${OPT_LEVEL}
.C.o:
${CXX} -c ${CXX_FLAGS} ${CXX_INCLUDES} -I${IBM_DB2_HEADERS} $<
It certainly compiles that way. I never examined the .o files to see if
they are optimized to level 2 and never checked to see if it is
scheduling properly for my Pentium IIIs and using Pentium III
instructions that are not in a 386, though. I do not know the difference
(from a programming in assembler) between the chips. I did know the 8086
and 80286 because I had to do some assembler-level programming for them
in the bad old days, but I could not tell for which chip *86 code is
intended.
With one suite of applications, -O3 does not work (it compiles OK), or,
if it does, it makes the programs so slow that I run out of patience
waiting for them. But this is a big dbms problem and perhaps the
applications compiled with -O3 are incompatible in some way with the
vendor-supplied API libraries or something like that. I did not persue
it because it is a client-server arrangement, and 99% of the time is
spent in the dbms server, so there is really not much point in
optimizing the client applications much.

Stick it somewhere where you do have write-permission, and when you
compile the application, tell the loader to look there for it. E.g., cc
all_your_dotOs, fullpath_name_to_library all_your_-l_flags
That is assuming the library is a .a file.
