Each ISOs directory contains a file called SHA1SUM that contains the SHA-1 hashes of the images. You can use a tool called sha1sum to calculate this hash from the image and compare it to the content of the SHA1SUM file. If the filename in the SHA1SUM file matches that of the image on your hard disk (and they are in the same directory), then run the following in that directory: $ sha1sum -c SHA1SUM Otherwise, you'll have to manually check the hash against the file contents: $ sha1sum image-name.iso (Note that these calculations will be very time-, disk- and processor-intensive. It takes just bit more than full minute of peak usage on my 2.4GHz Pentium 4 to calculate the hash of the FC6/i386 DVD image.) -- Peter Gordon (codergeek42) GnuPG Public Key ID: 0xFFC19479 / Fingerprint: DD68 A414 56BD 6368 D957 9666 4268 CB7A FFC1 9479 My Blog: http://thecodergeek.com/blog/
