I tried this using netcat and it works!

On the receiving machine (the one with the burner) run
Code:
nc -l -p 1234 | growisofs -Z /dev/sr0=/dev/stdin

On the sending machine (the one with the data) run
Code:
mkisofs [options] source_folder |  nc -w 1 aaa.bbb.cc.dd 1234

where aaa.bbb.cc.dd is the IP address of the receiving machine.

Very interesting approach as it sets the Bluray PC for receiving its data via sysin, while having the non-Bluray PC to "drive" the data. Netcat becomes the LAN subsystem active on both PCs which is the data carrier between each.

I think you use
Code:
growisfs -M ....
Very clever!!! Thanks @Rcrsn51

I don't think that it's possible using the netcat procedure. But here is an alternative.

1. Start a Samba server on the sending machine. The shared folder should contain the target data or a symlink to it.

2. Run a Samba client on the receiving machine and open the share.

3. Burn the data as usual.

I am looking at a new pBurn with isolevel 1/3/4.
I have decided to replace as little as possible. pBurn is well tested, and I don't want another 2 years with confused users.

Building the commands for the different isolevels, I came to one quest. pBurn today requires rockridge to be turned on to activate the -D switch. The next generation of pBurn has no specific option the set rockridge as it will be set for all isolevels. Are there any known issues by using the -D switch in combination with isolevel 1 ar 3?


Thank you
Sigmund

-D deep directory support.

No issue with ISO level greater than 1, will effect VERY old drivers trying to read ISO-level 1, but not newer than say 2004. If drivers can function with ISO level 2 then code is in place to support this, even if written as ISO 1

My view is the problems caused by lack of deep directory support, would exceed problems caused by using deep directory support in all versions of ISO levels.
Are you checking for directory inside of directories over 3 levels deep? If not we need -D flag. Wink

For what it might be worth, my audio book library is 3 directories deep: /mp3_books/author/book. Or is that technically 4 directories? As far as I know, books only contain mp3 files. I can't think of any that contain a directory.

-D

Ok, I have added -D switch to both isolevel 3/4. I think I leave isolevel 1 without - as an alternative.


Thank you Ted Dog
Sigmund

Sigmund, if I boot Fatdog 620 into RAM and then install your Pburn 4.1 .pet, should Pburn 4.1 be able to burn a 21 GB file onto a BD-RE disk? Pburn 4.1 in Precise 5.7.1 wouldn't burn the file. Sad

The cdrtools in 32 bit land is very dated, that is why it does not work. FD620 works fine, 621 works better ( cd drive reload issue solved in 621) if you want bootable and checksummed scripts good for 23.4Gs Blu ray reply back and Ill post them Friday.

Please do! Very Happy
I tried installing Pburn 4.1 in Fatdog64-620 but no joy. Pburn 4.1 tries to start, but stalls out after the first setup window, the one where you tell it where to put the buffer. After tha, it just shows the Pburn 4.1 window and goes no further. Same result when I enter "pburn" in a console. Sad

Did PBurn4.1 have dependency items required that might not be present in FATDOG620/LightHouse602?

Scripts.

./bluburn
Code:

------
#!/bin/sh
#growisofs -use-the-force-luke=notray  -Z /dev/sr0  -f -iso-level 4 -D -R  -V \"BluFatDog620\" -p root -publisher \"Ted_Dog\"  -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table ./
cd srs
growisofs -use-the-force-luke=notray  -Z /dev/sr0  -iso-level 4 -D -R -b isolinux.bin -c boot.catalog -no-emul-boot -boot-load-size 4 -boot-info-table ./
eject /dev/sr0
-----




MD5 construction script called zmd (place in same high level directory as boot files)

zmd
Code:


#!/bin/sh
cd srs
find . -type f -print0 | xargs -0 md5sum | grep -v "\./md5sum.txt" |grep -v "\./isolinux.bin"|grep -v "\./zmd"> md5sum.txt
rm zmd



CAUTION zmd is self deleting, no need to have it in resulting burnt disc. SAVE a copy.

The isolinux.bin file CHANGES for each different bluray, get a fresh copy from /usr/share/syslinux if you are going to copy from an existing iso file or burnt DVD. That is why its NOT added to md5sum list, its going to change!

to check burnt disc, open disc, open terminal from disc (I use ~ shortcut ) and type
Code:
 md5sum -c md5sum.txt


All OK's its good!

PostPosted: Fri 14 Mar 2014, 01:42    Post_subject: Fatdog64 630 fixed 8G boundaries issue  

Unexpectedly fixed the problem with multisession past the 8G mark was discovered in v 630... So full BluRay multisession disks are now doable without size limits to size of media... currently my last test disc is at 23.3G and should error out at 23.54G at true limits unless overburn is allowed like some DVDs... wonder how long it could over write.... Very Happy
