Right.

73:5 You haven't done the math right?

Currently i get 80Min CDRs for 0.80 DM (roughly 0.40$) per piece. So i could
record 50MB more. But i have only 1.1 GB for 1.3(2x74Min)-1.4(2x80Min) so
i haven't changed the script. :-)

I know. And i pracitise that more or less often. But for THIS case that
isn't an option.

Thats the big question.

cdrom_speed, which issues an ioctl, doesn't work.
cdctl doesn't get anything right. (It can't even eject a CD)

I have the following "Problem". I have a single file as the output of a
pipe that i wan't to burn on a cdr.

Is there a way to circumvent writting that file into a directory and then
"mkisofs"ing that directory?

A way of directly piping that file into mkisofs like

mkisofs --one_file_from_stdin --filename=file --filesize=681574400 <...>

Write a script that (hard/sym)links all Files into an other. Then create
an image from "the other" dir.

Burning a single file, comming from a pipe, onto a CD-R

Many, many, many month ago i asked how i could burn a single file, comming

Someone suggested to use a FIFO. Today i tried that.

mkdir testdir
mkfifo testdir/testfile
dd if=/dev/zero of=testdir/testfile bs=1024 count=1024

mkisofs -r [-f] -o image1.raw testdir

You aren't any better.

Your MUA is "broken", "misconfigured" or (User is) "ignorand"

Your MUA doesn't set the "In-Reply-to" and/or "references"-Headers

Discussions with more than "a few" Mails (With a high percentage from you)
are absolutly HARD to read because no thread-tree can be build.

Sometimes there are Threads with >100 Mails in L.K.M.L., but nearly
everybody has correctly configured MUAs (Even "pine" does it correctly) so
you have a "perfect" thread-tree. (At least ALL regulars use "good" MUAs
(Linus, Alan, Andre, Andrea, David ...) Sometimes this works so good that
you can't see the thread "correctly" anymore, because the tree is so wide
that it grew over the right border.

You want people to write emails to the gtar Authors to convince them to
make gtar POSIX-compliant.

Conclusion:

YOU have to write a complain to the authors of that programm, so that they
will make it "compliant" to RECENT Email-Standards.

(Or patch it yourself, implementing this feature should be TRIVIAL)

Btw. You know that RFC-822 is "deprecated", RFC-2822 is now THE
Email-Standard. (I don't KNOW it, but i think those headers are defined in
RFC-2822)

Conclusion:

EMail-Programm violating RFC-2822 have to be FIXED.


Maybe i should fetch RFC-2822 and look if you HAVE TO fix you MUA.

cdrecord "weakness"

2001-06-16 Thread Matthias Schniedermeyer

#include 


cdrecord has a problem with SCSI-(RAID)-Controllers that don't allocate a
ne scsibus for each Channels.

Yesterday i got a 5 Channel FAST-SCSI RAID-Controller (ICP-Vortex)

I have 4 CD-Rs and every one has a dedicated channel on the new
Controller. First i had configured every CD-R to ID-0. But then cdrecord
could only see the first one. Now i configured every drive with diffrent
IDs (cdrecord -scanbus attached). But that's not "the(tm)" solution.

AFAIK other OSses use "Adapter,Channel,ID,Lun" Adresses too. Why does
cdrecord "only" use "scsibus,ID,Lun" (Hmmm. Do ANY cases exist where the
LUNs are needed? (i only know 1 case, SCSI2SCSI-Bridges which map the ID
from the "slave"-Channels to LUNs of the ID on the Main-Channel. But i
think those bridges are "unusual")

BIG FAT BUG in cdrecord

When you abort cdrecord while the 10 second "last chance" then cdrecord

That destoy me an image because my burn-script does "if burning ok then
delete image". (And i accedently called the false script, then i wanted to
abort and use the correct one. I should have aborted at the "wrong" point,
which gives an errorleven != 0)

It cost my CPU 1335m of "99,9%" running the "undelfs" from "Midnight
Commander" (The only undelete-program i'm aware of)

At least current "ETA" is at 1335m (8,42KB/s for a 660MB file (If i would
to the same copy with "intact" file, that it takes <30 seconds). I still
don't know if the file could be rescured. (98% done)

Nobody knows you software as good as you. :-)

Does the Teac CD-R58S support RAW writing?

> But you are right, cdrecord better should do exit(2) in this case.

:-))) I'm happy now. I don't know if it's the first time you say my
opinion was right, but at least you share my opinion this time, so my burn
script won't delete an image "in error" another time. :-)))

That 100% useless

Burning 4 CDs in parallel(+X +mpg123 + ...) gives me a "phaenomeal" load of 
0.07-0.14 (0.04-0.06 without the 4 cdrecords!)

Each cdrecord has between <1% and 4% in Top

Even mpg123 needs (much) more CPU-Power to play MP3!

And cdrecord can get burn "faster" by optimized compiling!

System:

With exactly this configuration this specific cdwriter (And the other 3)  
worked before the power outage.

Thats the reason why i prefer dedicated SCSI-Channels. e.g. I used 
a dedicated (5 Channel)-Fast-SCSI-RAID-Controller when i used
4 Teac-CDR-58S for burning CDRs. (In total Linux showed 10 SCSI-Channels)

Then even Solaris should't have any problems with disconnect/reconnect
incapable devices.

> Solaris currently only supports video cameras over FireWire.

You should urge the Solaris-Firewire-People to implement SBP-2.
Then the whole range of Mass-Storage devices is suddenly usable, as all devices
(i know) use SBP-2 (Serial BackPack Protocol 2 = SCSI over Firewire)

"NoName" 5,25" Enclosure, maybe from MaPower. The Pioneer DVR-A03 is
built into this one.

And for HDDs i have a 2,5" and a 3,5" Enclosure each with an "Oxford
911" Chipset (Because of the performance, AFAIK this Chipset is still
the fastest available IDE <-> Firewire "converter"-chipset. It can reach
up to 33MB/s.). The 3,5" is called "IceCube" and IIRC the 2,5" is called
"ClearView" (Both are from Mac-Shops in Mac-like designs" (Thats
positive!))

If i take a non-CSSed DVD (*1) What do i have to burn a DVD(-R)-Video

and then just burn this image to a DVD-R?

If thats what it needs to burn a DVD-Video. Then it sounds much to easy.

mkisofs should die with too big files

2002-05-13 Thread Matthias Schniedermeyer

#include 



Yesterday i lost a 2,3 GB big file because mkisofs "silently" skipped it.

mkisofs ... $dir && rm -rf $dir

I had the luck that i can reget that file. But next time it's possibel
that i'm not so lucky. So it would be best to "die" instead of a "silent"
warning that a file was skipped. (At least as a commandline-option.
Something like the "Make warnings to errors" from compilers (this can be
especially usefull for scripts where the warnings aren't seen (Today i saw
the warning because i was watching the process today)). Or a special
option "die when files are too big")

Like i said. In a script that IS silent.

start script, "(go/look) away", script done, source-dir deleted,
image too small -> file lost. (Warning scrolled away. Yes i prefere the

"Should" is the jumping dot. All files names SHOULD not contain this or
that characters. All file names should be 8.3 (or 20/32 Chars?).

My filenames are too long. My filenames aren't Windows compatible.
(Windows refuses to read the files. I had to use "isobuster" to copy a
file off one of my DVD-Rs once)

So why should i be so "compatible" to put an ISO onto the Disc? Some
days ago i even thought about using romsfs, cramfs, FAT or something
else. Linux can read everything. -> No problem for Linux means no
problem for me. I even burned tar-files directly to CD-r in the past.

All or nothing. UDF means that the ISO can have lesser files than the
UDF part -> no ISO at all. A missing file isn't acceptable.

You should make mkisofs more correct. It should refuse to make
incompatible disc by default. Currently it says nothing when filenames
aren't compatible and/or filenames are to long. (Or "-r" and/or "-J"
switches that behaviour off. That are the only options i use)

I grep for the "print" myself and put the "exit 1" behind it myself. But
i would prefer to not do that with every release in the future. I'm OK
with a commandline-option i can put into my image-creation script. (And
i think my other would prefer such on option, or mkisofs to die when i
skips files. I think most people didn't notice that behaviour because
not so many use DVD-R currently. Like the "You have 10 seconds left" in
cdrecord that did "exit 0" in the past, when you pressed "Control-C".
Nobody noticed that, but my script just wippes the image when cdrecord
does an "exit 0", so i lost an image (I had the luck that "Midnight
Commander" could restore that file. But that took 24 hours) Same with my
image-creation script. It BELIEVES mkisofs. When mkisofs says
"everything OK", then everything is OK and the source-files can be
wipped. This behaviour destroys that "trust" situation.)

Now everything is right for my script.

a "#include " at the top

and a "_exit(1);" after the "errormessage" and everything works
flawlessly now and the script doesn't wipe a directory from which a
BROKEN image was created from.

Then hardwire "exit 0" into mkisofs & cdrecord. No need to tell any
script (or other programs) that there has been an error. It's totaly
pointless to tell there there was an error. Everything in one go or
nothing at all, there is good chance that everything worked fine. I've
recorded around 200 DVD-Rs without problems. So the error percentage is
less then 1 percent. Why care for problems less then 1 percent.

No other program comes currently to my mind where i need output-parsing
to get the notice of a FATAL error. (You know that the "file too big"
means that at least half of the content (seen from the size point) is
missing from the image? And in my eyes thats a FATAL error. Maybe i
should do it the other way around and place a filesize checker into my
image-creation script, but why should i do that hassle when mkisofs
could just throw an error?)

Re: mkisofs should die with too big files

2002-05-13 Thread Matthias Schniedermeyer

Hi


You are "strict" or you are not strict. If you are not strict that it is
pointless to talk about being strict. Someone else would say that Joerg
is just "inconsequent".

"Silently" IGNORING a file can't be the behaviour of a program that is
used in an automatic process. (And placing checks before or after
image-creation can't be the job of my script. "mkisofs" is specialized
in doing the job, so it should do it correct or die with an
error(level))

First: IANAL, AFAIK & AFAIR!

The "biggest" difference is that in the US you can "give up" (e.g. sell)
your authorship-rights (to use Joergs nomenclature) while in germany
this is impossibel.

Regarding GPL/PD/BSD/... this means that you (if you are german)
"tolerate" violations of your rights.
(You have the rights, but you don't use/enforce them.)

e.g. It would be easy for a german to forbid another german to use his
GPD/PD/BSD/... software. In the US this not be possibel, because you
give up this/that right(s). In germany you can't give up that right, you
just don't use it.


AFAIR there has only been one case where a german has "missused" his
german right(s) forbid another german to use his software. Unfortunatly
i can't remember any details.

You can burn any filesystem that Linux can read onto a CD. Or no
filesystem at all.
e.g. you can burn a .tar(.gz) file directly onto a CD.

Want you want seems to be "packet-writing".

With packet-writing you use the CD-R(W) in a HDD like way(*).

AFAIK there is something like this for Linux, but can't say anything
more.

"When you don't know what you are talking about. Shut up". :-)

You can't make a single file bigger than 2 GB in an ISO-Filesystem,
corect. But that is a limitation in of the ISO-Filesystem itself.

With any other filesystem (or not filesystem at all), that is capable of
having bigger files, you don't have that problems.

When you have a problem creating the 4.5GB Image-File then your system
isn't up to date. Update the system or use the split-option of mkisofs.

I burn DVD-Rs for more than a year now and from day one on i had never
problems with file-sizes (*1) (*2)



*1: Except that i had to patch the ISO-driver in Linux (kernel 2.4.9) to
recognize files bigger than 1 GB. But that patch made into "normal"
Linux a few revisions later.

*2: I don't count the 2GB Limitation of ISO-fs as a problem. As it is
conceptual there is nothing you can do about it.

As i said below. That problem doesn't exist (anymore). :-)
The 2GB problem is the only size-problem i know. So i included the rant
about that limitation to make a (more or less) technically correct
statement.

You should rename the program. It doesn't "feel" correct anymore. OK
currently you can't skip the ISO-FS. But AFAIR you once said that you
will make it possibel to skip the ISO-FS from the image.

A few month ago i even read an articel in our "Linux Magazin" about the

For burning i only had to recompile mkisofs because the version from my
distribution wasn't compiled right, it couldn't create an image >2GB.
But besides that i didn't had to change anything else in my system.

So i've never splitted my images, since the 2GB Barrier was gone since
2.4pre and i used 2.4.4 or 2.4.9 the time i burned my first
DVD-R.

For reading files bigger 1GB the kernel had to be patched because
otherwise the file would be shown as 16MB or something like that.

No keys back then. The binary was the key, i got my "own" cdrecord. The
keys came later.


And another "thing" i never had problems with and where other people
have a variing milage is firewire.

Since day one i use the DVD-R connected via a IDE <-> Firewire
enclosure. It took about 10 "try"s until i finally had my first
DVD-R-coaster. :-)

Even if DVD+RW is "superior" to DVD-R. What does it REALLY buy you?

Is there any REAL practical use for writing to the 4GB position on a
virgin media?

And personally i would NEVER use a rewritable medium that isn't build
into a caddy. (Neither - or + fit this requirement. DVD-RAM would fit)

As i "joke" i bought 2 DVD-RW media and used them to transport some data
to a college of me, after 3 rounds the media weren't usable anymore,
because of to many scratches. So the R(e)W(rite) is more theoretical
then practical in my eyes. (OK there are "DVD+R" now)

If i need TRUE "random" access, DVD-RAM is much better for the job. OK
disadvantage is that nearly nobody has this (if you want to use such a
media to transport data.) and even if DVD-RAMs were readable by a normal
DVD drive the media wouldn't fit because i haven't see a DVD drive with
a caddy latly.

For transporting data to/from the place i work i use a 20GB 2,5" HDD
build into a firewire-enclosure. With around 15MB/s this outperforms
everything else on the portable market. (Excluding 3,5 HDD built into a
firewire enclosure)

Again. Even if DVD+RW is "superior". What does it REALLY buy you?

Excluding the 0.01% of the person that can actually use some or all of
the benefits.

There are 99.99% of the people that don't care and/or don't need such
benefits.

To take myself. I burn for about 6 years now. I have NEVER used CD-RW
(Actually the DVD-Burner is my first burner that supports CD-RW and i
would NEVER use my DVD burner to burn CD-R(W)) and i have NEVER used
multisession or things like that (This includes packetwriting which is
only other way to gain the (same/similar) effect that you can get with
multisession).
And i don't know any person in my surrounding that uses/needs such a
feature.

To say it simple: The price-tag and/or the availability will settle the
DVD(+/-)R(W) "war".
(Or all manufractory will make drives like the announced drive from sony,
that supports both formats. Then the price-tag of the media will settle
the "war")

e.g. Verbatim is good. I've use them for nearly 1.5 years now and i had

For 2x burning the firmware of the burner must know the write-strategy

Fallback to 1x. (*)

For 4x you have to wait until they get available. AFAIK currently you
can't buy 4x DVD-Rs.

Ups. I forgot that totaly. As i've always had a license i forgot that
you can't burn fast with the free license.

When i read 'Burn faster' my first thought was that you have "cheap"
medias that the firmware doesn't recognize. But you need both. Good
media and a "better" license.

I paid 100 EUR and AFAIK the price hasn't changed.
But i don't know if Joerg charges less for students.

You have to ask Joerg directly for more information. I've always used
one of the email-adresses in the readme of cdrecord to mail Joerg.

OK. I take this point.

But IMHO you should make the speed-limit-paragrah in the README at bit
more understandable. At least that the speed-limit only hits the
clone-feature isn't written 100% clearly in my eyes.

You confuse yourself.

cdrecord-proDVD has it. cdrecord doesn't.

cdrecord-proDVD != cdrecord
(Per dictionary definition of "equal", "identical" ...!!)

It depends. ;-)

When you have a "good(tm)" connection the the internet you only need a
very basic installation and the rest can be done over the internet.
So you only need the first disc.

Otherwise it depends on what software you want to install.

As a german you should know that english doesn't differentiate "free".
"Free as in beer" vs "Free as in speech" are both "free" in english.

So the translation is a valid point.
Guess why it is called "Open Source Software" and not "Free Software"!

The proDVD version is ONLY as "free" as free beer .

With the upcoming Linux-2.6 Kernel you will be able to burn with full
speed because the 2.6-Kernel can talk to the burner in DMA mode.
Current 2.4 Kernel isn't capable of doing this.

Personaly i have my burner plugged into a Firewire-Enclosure, a good one
talks with DMA to the burner.
I have a 4x DVD-Burner (equals roughly 28/29x CD-Speed) and had never
problems with burning. I never use burnfree.

Ups. I have to admit that i never burned via IDE directly.
I jumped directly from SCSI to Firewire because i hadn't had a free 5

No Prob. I make/use >4GB images for more than 2 years now.

As long as you have a current(tm) distribution and a >=2.4.0 kernel
there is no problem.
(And "current" here means that the distribtion compiled with a kernel
>=2.4.0, so that LFS is enabled)

2 years ago i had to compile my own mkisofs, because "back then" the
SuSE-mkisofs wasn't compiled correctly(tm).

They don't need the size?
They want downloaders to be able to download it with Windows 95/98?
(AFAIK 4GB is the maximum filesize for FAT32)

Definetly NOT.

e.g. "grep".

grep only uses libc-interface. As long as the program <-> libc interface
is stable it will have no problem with the libc <->  site.

It is excatly THE job of libc to abstract away the "right" side.
(Or the left when you assume hardware/kernel is leftmost)


Only "system dependend"(hardware, kernel interfaces, ..) software (e.g.
cdrecord, star, ps, lspci, iptables) have this type of problem.

And btw. There is also a "binary" and "compile" compatiblity factor in
this.

e.g. libc6 aka glibc2 broke compatiblity with libc5 so A FEW programms
needed patches to be COMPILABLE on new systems whereas (when the needed
shared libraries where installed or the programm was static compiled)
the libc5 binaries where still runable.


Or in other words for >95% of all programms your statement is false!

There is, always was and will ever be a small fraction of programs with
this type of problem. The majority of software doesn't have this type of
problem(s)!

Or in other other words:

It is wrong to assume that a random system dependend program compiled
for OS revision A will run correctly on OS revision B for system.

I have more other words:

If Linux (for 2.8/3.0 whatever) would get incompatibel to every other
Unix(type) OS AND to POSIX, BSD (and would need to drop glibc2). Then
you can say what you have said.

If you say it this way, then you even have to say:

You can't assume that a random programm compiled for OS Revision
A.0.0.0.0.0 will run correctly on OS revision A.0.0.0.0.1

They MAY be a subtle bug that prevents the 10thousands program to run
correctly.

Take this "as given".

Same as you can assume that the libc of Solaris 9 is compiled on Solaris
9 and is forward compatible to Solaris 8.

Exactly.

I would say:
It is save to assume that a system independend program has a chance of
99% to work in the next Revision.

I said FORWARD compatible.
Which means: A program compiled on Solaris 8 works on Solaris 9.

Which should be true for system independend programs in 99% of the cases.

No Prob. I make/use >4GB images for more than 2 years now.

As long as you have a current(tm) distribution and a >=2.4.0 kernel
there is no problem.
(And "current" here means that the distribtion compiled with a kernel
>=2.4.0, so that LFS is enabled)

2 years ago i had to compile my own mkisofs, because "back then" the
SuSE-mkisofs wasn't compiled correctly(tm).

They don't need the size?
They want downloaders to be able to download it with Windows 95/98?
(AFAIK 4GB is the maximum filesize for FAT32)

Definetly NOT.

e.g. "grep".

grep only uses libc-interface. As long as the program <-> libc interface
is stable it will have no problem with the libc <->  site.

It is excatly THE job of libc to abstract away the "right" side.
(Or the left when you assume hardware/kernel is leftmost)


Only "system dependend"(hardware, kernel interfaces, ..) software (e.g.
cdrecord, star, ps, lspci, iptables) have this type of problem.

And btw. There is also a "binary" and "compile" compatiblity factor in
this.

e.g. libc6 aka glibc2 broke compatiblity with libc5 so A FEW programms
needed patches to be COMPILABLE on new systems whereas (when the needed
shared libraries where installed or the programm was static compiled)
the libc5 binaries where still runable.


Or in other words for >95% of all programms your statement is false!

There is, always was and will ever be a small fraction of programs with
this type of problem. The majority of software doesn't have this type of
problem(s)!

Or in other other words:

It is wrong to assume that a random system dependend program compiled
for OS revision A will run correctly on OS revision B for system.

I have more other words:

If Linux (for 2.8/3.0 whatever) would get incompatibel to every other
Unix(type) OS AND to POSIX, BSD (and would need to drop glibc2). Then
you can say what you have said.

If you say it this way, then you even have to say:

You can't assume that a random programm compiled for OS Revision
A.0.0.0.0.0 will run correctly on OS revision A.0.0.0.0.1

They MAY be a subtle bug that prevents the 10thousands program to run
correctly.

Take this "as given".

Same as you can assume that the libc of Solaris 9 is compiled on Solaris
9 and is forward compatible to Solaris 8.

Exactly.

I would say:
It is save to assume that a system independend program has a chance of
99% to work in the next Revision.

I said FORWARD compatible.
Which means: A program compiled on Solaris 8 works on Solaris 9.

Which should be true for system independend programs in 99% of the cases.

No.
You can use RSA/DSA keys. And with keys you also have the possiblity to restrict the 
commands users can invoke at "login"-time, so you COULD e.x. restrict a login 
with key XY to only be able to call cdrecord.
Keyword: command(="/usr/bin/cdrecord") in authorized_keys
But i don't know how "good/secure" this is, never used it myself.
