The results I have for the RHN RHL 9 CDs are as follows (in units of
2048 byte blocks). I have verified the md5sum's for these files.
shrike-i386-disc1.iso 326656
shrike-i386-disc2.iso 330816
shrike-i386-disc3.iso 248336
shrike-i386-disc4.iso 311408
shrike-i386-disc5.iso 330416
shrike-i386-disc6.iso 217360
A good way to find the size of an ISO 9660 volume:
isosize -x shrike-i386-disc1.iso
or
isosize -x /dev/cdrom
The output for this example:
sector count: 326656, sector size: 2048
Alternatively, one may look for the lines labeled "logical block size"
and "volume size" in the output of:
isoinfo -d -i shrike-i386-disc1.iso (or, e.g., /dev/cdrom)
BTW, as I understand it, the RHL 9 ISOs that may be downloaded from
Red Hat Network are not identical to those shipped in the box sets.
The ISOs from RHN are more recent than the boxed set ISOs and already
contain several of the errata that have been released against RHL 9.
Therefore, when talking about MD5 sums of RHL 9 CDs one needs to
specify whether one refers to the downloadable ISO files or the boxed
set CDs.
