Description
This test is intended to verify that the posted ISO media matches the published sha256sum.
How to test
- Download the
.isomedia files you wish to test - Download the matching CHECKSUM file. For example,
Fedora-15-i386-CHECKSUM. - Validate that the published CHECKSUM matches the downloaded ISO files by running the command
sha256sum. For example, you might type:sha256sum -c Fedora-15-i386-CHECKSUM
- For all installation ISO images (does not include Live ISO images), validate the md5sum imprinted inside the ISO image. First, install the
isomd5sumyum install isomd5sum. Next, to check all ISO files using thecheckisomd5command, you might type:for ISO in Fedora-*.iso ; do echo "= $ISO =" ; checkisomd5 $ISO ; echo; done
Expected Results
- The command
sha256sumshould return OK results. For example:- $ sha256sum -c Fedora-15-i386-CHECKSUM
- Fedora-15-i386-DVD.iso: OK
- Fedora-15-i386-netinst.iso: OK
- The command
checkisomd5, when run against installation ISO images (not Live ISO images) should indicate that it is OK to use this media for each ISO image. For example:- The media check is complete, the result is: PASS.
- It is OK to use this media.
