The nfs file system does not understand the concept of lsattr etc
so even though the underlying ext2 fs does, it cant cross the nfs
rpc system.
The spool dirs on my sys have the perms
drwxr-xr-x 17 root root 1024 Dec 20 16:50 /var/spool
drwxr-xr-x 3 lp root 1024 Dec 8 17:39 /var/spool/lp0
drwxr-xr-x 2 lp root 1024 Mar 15 11:33 /var/spool/lp0/unix
and the files in them have
-rw-rw---- 1 bin lp 104 Mar 8 16:34 cfA003rockhopper
-rw-rw---- 1 bin lp 84 Mar 15 11:33 cfA004rockhopper
-rw-rw---- 1 steve lp 25 Mar 8 16:34 dfA003rockhopper
-rw-rw---- 1 root lp 25 Mar 15 11:33 dfA004rockhopper
-rw-r----- 1 root root 4 Apr 21 09:25 lock
-rw-rw-r-- 1 root root 43 Apr 21 09:25 status
One key aspect is whether the various users (esp lp & bin) have the
same uids on all boxes and the same group memberships, but as
it is mounted from the server then I *guess* that all of that
is correct... presumably needs to be mounted with no_root_squash
to allow the lpd exe to write into dir.
The only other suggestion is to check with df that there is
space in the dir... the other one is to print using strace eg
strace -o/tmp/dbin -f -t lpr myfile
(or with whatever lpr options you use),
and check the open,write and close of the cf file.
I have a printing check that may be of use at

Hi,
I just started running linux about a week ago, and love it.
I am running Linux Mandrake 7.0 on a Pentium III - 450, 128mb RAM.
I've run into a problem with my login though. When a user logs in the Bash
shell which is default doesn't seem to beoperating properly. After the
user logging in enters their password, the following line is displayed:
/bin/bash: dircolors: command not found
When the user tried for example to execute /bin/ls or another command the
following is displayed:
/bin/bash: dircolors: command not found
/bin/bash: id: command not found
/bin/bash: tty: command not found
(Note running ls from an directory other than /bin will not do anything
(bad command returned) so I assume paths are not being set).
This only happens with accounts I've setup, and not the root account.
Onlogin with root I do get one error:
grep - command not found
I try executing grep after login completes, and it executed okay.
On another note, I was wondering where the login scripts are stored for
each user? Thanks for the help.

We have several linux machines (RH 6.1) which all NFS mount /var/spool/mail
from one machine. Regular users can read mail from any machine. But only
root on the server can read root's email. Root on other machines gets
the error:
Cannot flock folder "/var/spool/mail/root"! [No locks available]
Is there a way to either allow root on all machines to read a (common)

Dia is a program designed to be much like the Windows
program 'Visio'. It can be used to draw different kinds of diagrams. In
this first version there is support for UML static structure diagrams
(class diagrams) and Network diagrams. It can currently load and save
diagrams to a custom fileformat and export to postscript.
QCad is a professional CAD System. With QCad you can easily
construct and change drawings with ISO-texts and many other
features and save them as DXF-files. These DXF-files are the
interface to many CAD-systems such as AutoCAD(C) and many others.
Xcircuit is a general-purpose drawing program and also a specific-purpose
CAD program for circuit schematic drawing and schematic capture. Output
is PostScript.
Cycas is a complete 2D+3D CAD package for X11.
Some of its features: Easy to use GTK+ Interface, WYSIWYG display,
printing, plotting, import/export filters, photorealistic rendering,
special methods for architectural design, full HTML documentation,
tutorials, example drawings, fonts and symbols.
Sketch is an interactive X11 drawing program (similar to XFig or tgif).
It is written almost completely in Python, an object oriented
interpreted programming language.
Xfig is an X Window System tool for creating basic vector graphics,
including bezier curves, lines, rulers and more. The resulting
graphics can be saved, printed on PostScript printers or converted to
a variety of other formats (e.g., X11 bitmaps, Encapsulated
PostScript, LaTeX).

Linux is Hard to Use: Part 3
Linux new user (NU) installation usage profile.
Expert comments are marked EX.
NU: I have heard a lot about Linux recently. It just seems like the
hottest thing around. I am going to install it on my machine. Can
it coexist with Windows 98? I don't want to give that up until I am
sure that Linux is working for me. What distribution should I use,
and how should I prepare my machine?
EX: You could try RedHat. Also, it is recommended that you purchase
a new hard disk. It is very likely that you have one hard disk, and
Windows is stored on one large partition taking up the whole disk,
and you will have to repartition the disk. There is a utility called
FIPS which you can use for this purpose, but it is risky. Are you
willing to risk your Windows data for a couple hundred dollars?
NU: No way! I can afford a new hard drive if it means that my
Windows data will be safe.
EX: OK, then, good luck!
(several days later)
NU: I've got a problem. Linux has destroyed Windows. I tried to
install to the second hard disk and now the computer just generates
010101010101010101010101010101010101010101010101010101010...
forever when it tries to boot. Also, I cannot boot Windows.
EX: Oh yes, the old lilo
010101010101010101010101010101010101010101010101010101010... bug.
You did make a boot disk? Why did you want to go back to Windows
anyway?
NU: Yes, I do have a boot disk, but I need to use Windows and it
is gone. Also, the reason that I need to use Windows is that Linux
will not do everything I need it to.
EX: Oh yes it will! What do you need? Games, office productivity
tools, graphics software, etc., just surf the web, and you will
find hundreds of applications for Linux.
NU: I need the video chip number. Autoprobe failed, and the
XFree86 configurator failed. I need a windowing system for some
applications. Windows can find out what video chip I have, but
Linux cannot. Do you have a www site for that?
EX: No, I can't think of one off hand. If you cannot boot
Windows, you could try opening the case and reading the chip
number.
(several days later)
NU: I could not find the video card. I think that video is
integrated into the motherboard. Why can Windows find it and
Linux cannot?
EX: That is caused by an old bug in Xconfigurator. It still
has not been fixed, but it has been reported. One wild guess:
Look for a chip with many pins that says SiS on the back, and
record the 4 digits after the SiS. This should help.
There is something that I should warn you about at this moment.
You will be tempted to return to Windows soon. And, you will
probably try to do something in a hurry, perhaps rashly. The
typical new user at this point will try to reinstall either
Windows or Linux, losing all kinds of data and configuration
time. This is complained about a lot on the 'net. Do not
rush back to windows. Fix the problems in your lilo
configuration file, and Windows will probably boot again.
Then, calm down, and take things slowly. You are asking for
Windows back, and the quick answer is to do fdisk /mbr, but
that is not what you really want. You want a dual boot
Windows/Linux system with Windows on the first hard drive and
Linux on the second.
(several days later)
NU: You were right. I paniced, and messed everything up. I
tried fdisk /mbr, and it did not work. It probably is not
supported anymore. Since it did not work, I tried to
reinstall Linux in a more conservative way. I opted for a
"Workstation" installation...
EX: Oh no! You can't do that! If you do that, you will
never be able to go back to Windows. The old "Workstation"
installation mode is too dangerous and it is old. You must
have an old CD-ROM.
NU: But it says nothing about not being able to go back to
Windows. I only found that out later when the Workstation
mode wrote two ext2 partitions over my first hard disk. The
manual does not say anything about this.
EX: Well, it should, and you should know better. This is a
typical new user profile.
NU: It gets worse. I tried to re-install Windows. It did
not work. There is a strange error. fdisk will not remove
the first partition since there is a second one. And it will
not remove the second one because there is a logical
partition in it. And, it will not remove the logical
partition, because it says that there is none.
EX: This is a well known bug in Windows.
NU: That information does not help me now! Why didn't it
warn me before I tried installing?
EX: A warning would not have helped. You were screwed from
the very beginning, and the installation process toyed with
your emotions until you had no choice but to mess up in
exactly this way. The authors of the installation program
should have forseen this and tailored the installation
process to suggest a different path.
NU: Well, that doesn't help either! How can I get Windows
back?
EX: You will have to get rid of those two partitions.
Unfortunately, this is not easy. I checked linuxnewbie.org,
www.redhat.com archives, FAQ, etc., and there was no info on
it. Someone on the newsgroups said that this is an FAQ and
you can check http://sunsite.auc.dk/linux-newbie/FAQ.htm.
Unfortunately, that link is dead. But here is how to do it.
Go to the store and buy a copy of Partition Magic...
NU: I don't want to buy anything else! Will this be
guaranteed to work, or will it be like the second hard disk
that I bought that "guaranteed" that I would not lose any
Windows data.
EX: Calm down. You probably didn't lose anything important
anyway. There is a way to do it with Linux fdisk. Just run
fdisk from Linux and restore these partitions.
(several days later)
NU: I tried what you suggested, and it didn't work. fdisk
will not work on a root partition that is currently being
used by the running system. Also, I have to do this in those
hard-to-read text consoles.
EX: Oh yeah, that's right. I forgot. I never had to do this.
You will have to go through the install all over again, and set
the partition types of the first hard disk to DOS 16 FAT. Then,
you should be able to reinstall Windows. Of course, you'll lose
all your data, but you did back it up, didn't you?
NU: How about the video? I tried your suggestion, and there
was a chip that said SiS on it. The number did not quite match
the one in the selection box, so I chose the nearest one, and it
did not work. The screen came up, but at very low resolution.
The font was huge and unusable.
EX: Oh yes, the old low resolution bug! That is strange.
Nobody wants low resolution, but you still seem to get it if
something went wrong.
NU: What went wrong?
EX: I don't know. This is a well known problem. Lets check the
XFree86 Installation HOWTO. Oops, nothing in here. How about the
www.XFree86.org site. Oops, there's nothing in here either.
Hmmmmm, this is strange, I seem to recall that this is a very
common bug. How about www.redhat.com. Ahh yes, searching the
archives finds a whold bunch of hits. Hey, wait a second! Most
of these links are dead. Here we go, here is one that works.
Yes, someone is reporting the problem once again, and there is
someone named Manuel (presumably a support person) saying that you
should bypass autoprobing and select 800x600 directly.
NU: I already tried that. It didn't work.
EX: Well, I guess that I am kind of out of ideas. Maybe I should
post the query on comp.os.linux.misc. Somebody should have seen
this problem before.

I have restored a system from a tar archive as follows. I
first booted from a rescue system such as Tom's root boot disk.
I did what was necessary such as partitioning with fdisk.
Then I mounted the partition I wanted to contain the system
and I made a file system on it using mkfs or if not available
mke2fs. I then untar'd from the archive to the desired
partition. I then ran lilo from the mounted system using
lilo -r /a
where /a was the mount point. This should work, but there are
a few caveats. First, make sure you backup with a version of
tar similar to the version you will use to restore. For example.
the tar on tom's root boot disk does not have the z option.
(But if you work at it you can combine tar with gzip to do
the same thing.) Tom's root boot disk uses a 2.0.* kernel
so you could also have trouble using its fdisk with a partition
created with fdisk on a later kernel. If are not changing
partitions, you should be okay. Also, your system may be in
more than one partition, so you would have to restore each of
them separately.

I wanted to create a few simple .pdf's without having to learn a new
application, such as latex. So I tried to use WordPerfect (for Linux) and
capture the printed output in a file (which is postscript), and then use
ps2pdf to create the pdf file. Unfortunately, the ps2pdf utility did not
like the ps file created by WordPerfect. (???)
So I reverted to Netscape, using its html "composer". After creating the
html document, I printed it from Netscape, got the printfile and converted it
with ps2pdf. Not very elegant, but it got me by that "emergency".

Troll, all you've proved is sometimes it's hard to install
an OS on some particular hardware combinations. This is true
of *ANY* OS. I've had hardware on which Windows (*particularly* NT)
and various other very nice OS were very difficult to get up and
running on. Linux is NOT harder to use on average than any other.
They all have glitches in certain areas.
Your NU's mistake was probably to try and setup
some complicated multi-boot situation.
Why not just do the EASY solution?
Pull the original Windows drive, put it on a shelf.
Now put in your new test drive and install Linux.
If it turns out to be so frightening due to hardware issues
then they can just plug the original drive back in!
Is that so tough to figure out?
Apparently it is for you.

YES absolutely. LaTeX, using pdftex, will give you an appropriate file, and if you
use the hyperref package in LaTeX, your PDF file will be full of appropriate
references, hyperlinks, links to the index, a list of chapters and headings, etc.,
You can also convert a Postscript file to PDF using Ghostscript and its useful
companion script "ps2pdf". Can StarOffice do Postscript output? I should hope so.

sprintf() will normally do the trick, for (char*). If you must
use the 'string' class, substitute 'stringvar.data()' for the
char* ptr. Be warned that there must be sufficient space in
the char*/string...
sprintf() is standard C, and should definitely have a man page.

I'll leave the C++ book recommendations to others. Never been fond
of the string class.

It's not really a conversion, per se, in the usual sense. Changing
the base representation (say, 2's complement little endian, packed
in 32 bits) to a human-readable format (e.g. base 10, ASCII, bytes
in MSB->LSB order) is more drastic.

Hi ,
I have installed linux 5.2 on my machine and tried to run the
linuxconf command but it gave me an error saying "remadmin (GUI
frontend) exiting abnormaly".
when I tried to start linuxconf from the start menu nothing comes up and
also I am unable to open the control panel.
I am new to linux programming and have no idea where to look
for in case of such problems.Any suggestions in this regard will be
gratefully received
Thanks
Neelima

Right-click over the desktop, which should bring up Enlightenment's
'Settings' menu. The first entry there is 'Focus Settings',
which has everything you need.

You could also do a
tar -cPlz / -f ...
or a
tar -clzf /whatever/root.tar.gz -C / .
Either should avoid the creation of a record with a null file
name, corresponding to the root directory itself. (In the first
case, the name will be /, in the second it will be ./ . I think
the second is slightly preferable, as it makes it easier to unpack
in a separate subtree.)

Consider filing a bug report against tar (it could use "." rather than
"" as the file name) and/or star (it should be more robust).

The following appears to do *exactly* what you asked for:
pax -w -X -s :^/:: / | gzip > /whatever/root.tar.gz
pax is a great tool; it even lets you use regular expressions to
select and/or rename files on the fly. (And of course it's standard
POSIX and supports both tar and cpio formats.) I'm surprised
no one ever thinks of using it (well, hardly anyone).
Consider writing your archives in cpio (or afio) format rather than tar.
This is particularly important if you have pathnames that cannot be
split 155+100 at a slash separator (and I wouldn't be surprised to
learn that star doesn't support file names longer than 100 characters
at all).
If necessary, prepare another floppy disk with pax, GNU tar, cpio or afio
just so you can restore things more easily.
