pktsetup problem...
 

hi

i try to do packet writing under linux (suse 10)

in fstab i have

/dev/dvdram /media/dvdram subfs
fs=cdfss,rw,procuid,nosuid,nodev,exec,users,gid=users,umask=0002,iocharset=utf8
0 0

modprobe pktcdvd
modprobe udf
cdrwtool -d /dev/dvdram/ -q

pktsetup /dev/pktcdvd0 /dev/dvdram

i get ioctl: Inappropriate ioctl for device

linux:/var/lib/rpm # ls -ls /dev/pktcdvd*
0 crw-rw---- 1 root root 10, 62 2005-10-26 23:59 /dev/pktcdvd
0 --wx---r-- 1 root root 0 2005-10-27 00:11 /dev/pktcdvd0


any idea?

thanks

I sent this recently to the SUSE packet writing mailing list - it may help you. Note carefully the syntax of pktsetup - you can call the block device (that I named cdpkt) anything you like.

I think I may have the answer to this. I struggled for days to get this
working and had the same 'Inappropriate ioctl' error despite doing exactly
what every instruction told me. I use kernel 2.6.12 on Vector Linux and
the latest udftools-1.0.03b. However, I finally found this site run by the current
maintainer :

http://web.telia.com/~u89404340/packet.html

on which he said to apply this patch to the latest udftools even for
kernel 2.6 :

http://web.telia.com/~u89404340/patc....0b3.patch.bz2

That did the trick for me and it all works perfectly.

What happened was that <modprobe pktcdvd> created the directory
/dev/pktcdvd and <pktsetup cdpkt /dev/hdc> created the file
/dev/pktcdvd/cdpkt. Problem was that this was an empty text file
instead of a block device - hence the 'inappropriate ioctl' error.
Patching the udftools made it create a block device instead that pointed
to my cdrom /dev/hdc.


I put this in /etc/fstab :


dev/pktcdvd/cdpkt /mnt/cdpkt udf noauto,user,rw 0 0


amd made a folder /mnt/cdpkt to contain the contents.


I then put pktsetup /cdpkt /dev/hdc in my /etc/rc.d/rc.local so it
registers automatically every time I bootup.


Hope this helps. My researches showed lots of people seem to have this
problem, and the need for the patch is not at all clear - all sources
implied that the latest udftools-1.0.03b together with kernel >= 2.6.10
should work. Seems not so.
