Several machines on the cluster have CD-RW drives and may be used for burning CDs. The program cdrecord is configured to allow users to burn CDs. Cdrecord is a command-line tool, but there are also GUI frontends for it (such as?).
The nodes that are enabled for CD burning include: hx1, hx2, hx4, sasha, saturn. Senna has a DVD-RW. Note that these machines have the proper default options for cdrecord set; the user doesn't need to specify the CD device using the -dev option to cdrecord.
To burn an ISO image to CD, on one of the enabled nodes, do the following:
- login to the node (can be a remote connection, if no one else is logged in at the console)
- put disk in drive
- run cdrecord command
An example cdrecord command is:
cdrecord -dao file.iso
To blank a CD-RW disk, do:
you can also use -blank=fast and also the -force option.
cdrecord is setup with setuid. The file /etc/cdrecord.conf should be setup as follows:
root# chmod u+s /usr/bin/cdrecord
root# cat /etc/cdrecord.conf
# devicename device speed fifosize driveropts
cdrom= 4,0,0 -1 -1 burnfree
