Linux: Burn multi session CDs on Linux

Posted on in Categories CentOS, Debian Linux, File system, Gentoo Linux, Hardware, Howto, Linux, Linux desktop, RedHat/Fedora Linux, Suse Linux, Ubuntu Linux last updated December 7, 2007

Under Linux you can use tool called cdrecored (use to record audio or data Compact Discs) with mkisofs (use to create an hybrid SO9660/JOLIET/HFS filesystem with optional Rock Ridge attributes ) for this purpose.

Step #1: Create first session as follows

1) Create an iso image first:

# mkisofs -R -o /tmp/cd.iso /backup/06-07-2004/


  • -R : Uses Rock Ridge naming convention/attributes
  • -o : Name of new iso file (cd.iso)
  • /backup/06-07-2004/ : Everything in /backup/06-07-2004/ will be put into cd.iso file

2) Burning the disk (or an ISO image) for first session:

# cdrecord -dev=0,0,0 -multi -data -v -eject -speed=4 /tmp/cd.iso


  • -dev=0,0,0 : device number (tip you can use cdrecord -scanbus command to get this number)
  • -multi : Start multi session disk
  • -data : This option required for HP and Sony CD Writer only.
  • -v : Verbose i.e show info while burning the disk
  • -eject : Ejects the CD when done
  • -speed=4 : Write speed (4x)
  • cd.iso : Name of image being burned

3) Mount cdrom and see the contains:

# mount /mnt/cdrom
# ls /mnt/cdrom
# rm -f /tmp/cd.iso

OR< pre># mount /dev/hda /mnt/cdrom; ls /mnt/cdrom; rm -f /tmp/cd.iso
4) You can also verify that how many sessions written so far:

# umount /mnt/cdrom
# cdrecord -dev=0,0,0 -toc


  • -dev=0,0,0 : Device number
  • -toc : Retrieve and print out the table of content

Step #2: Burning the disk (or ISO image) for next session

Next session is bit tricky. You need to specify last sessions starting and ending sector numbers this information can be obtained from the following command:

# cdrecord -dev=0,0,0 -msinfo



1) Create next session ISO file:

# mkisofs -o /tmp/ses2.iso -R -V session2 -C $(cdrecord -dev=0,0,0 =msinfo)
-M 0,0,0 /backup/07-07-2004


  • -C $(cdrecord -dev=0,0,0 –msinfo) : This option is needed when mkisofs is used to create the image of a second session or a higher level session for a multi session disk
  • -M 0,0,0 : Specifies path to existing iso9660 image to be merged.

2) Burning the disk (or an ISO image) for second session:

# cdrecord -dev=0,0,0 -multi -data -v -eject -speed=4 /tmp/ses2.iso

3) Mount cdrom and see the contains:

# mount /mnt/cdrom; ls /mnt/cdrom; rm -f /tmp/ses2.iso


# mount /dev/hda  /mnt/cdrom; ls /mnt/cdrom; rm -f /tmp/ses2.iso

Note: When you wish to close disk (multi session cd), omit the -multi option for last session.

How to mount remote windows partition (windows share) under Linux

Posted on in Categories CentOS, File system, Howto, Linux, RedHat/Fedora Linux, Suse Linux, Sys admin, Tip of the day, Ubuntu Linux, UNIX, Windows, Windows server last updated August 3, 2007

All files accessible in a Linux (and UNIX) system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree.

Use the mount command to mount remote windows partition or windows share under Linux as follows:

Procedure to mount remote windows partition (NAS share)

1) Make sure you have following information:
==> Windows username and password to access share name
==> Sharename (such as //server/share) or IP address
==> root level access on Linux

2) Login to Linux as a root user (or use su command)

3) Create the required mount point:
# mkdir -p /mnt/ntserver
4) Use the mount command as follows:
# mount -t cifs //ntserver/download -o username=vivek,password=myPassword /mnt/ntserver

Use following command if you are using Old version such as RHEL <=4 or Debian <= 3: # mount -t smbfs -o username=vivek,password=D1W4x9sw //ntserver/download /mnt/ntserver

5) Access Windows 2003/2000/NT share using cd and ls command:
# cd /mnt/ntserver; ls -l

  • -t smbfs : File system type to be mount (outdated, use cifs)
  • -t cifs : File system type to be mount
  • -o : are options passed to mount command, in this example I had passed two options. First argument is password (vivek) and second argument is password to connect remote windows box
  • //ntserver/download : Windows 2000/NT share name
  • /mnt/ntserver Linux mount point (to access share after mounting)
