In case you are not sure how to go about this, try the following. 1. Make sure that the iso file: livedvd-amd64-multilib-20121221.iso and its hash file: livedvd-amd64-multilib-20121221.iso.DIGESTS are both saved in the same directory. 'cd' into the same directory. Depending on how paranoid you want to be with regards to checking the integrity of the downloads, you can also get the gpg signature of the file with the hashes and check that it has not been tampered with. First fetch the gentoo gpg keys. Use the KeyID of the (non-expired) keys from here: http://www.gentoo.org/proj/en/releng/index.xml and run 'gpg --keyserver subkeys.pgp.net --recv-keys '. For example: gpg --keyserver subkeys.pgp.net --recv-keys 0xDB6B8C1F96D8BF6D Download the signed file of the hashes: livedvd-amd64-multilib-20121221.iso.DIGESTS.asc Then check the integrity of it: gpg --verify livedvd-amd64-multilib-20121221.iso.DIGESTS.asc You should get something like: [snip ...] gpg: Good signature from "Gentoo Linux Release Engineering (Gentoo Linux Release Signing Key) " gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner. Primary key fingerprint: D99E AC73 79A8 50BC E47D A5F2 9E64 38C8 1707 2058 gpg: textmode signature, digest algorithm SHA1 Ignore the warning: "WARNING: This key is not certified with a trusted signature!" which is correct, unless you have manually edited the trust of this gpg key in your keyring. The line above it tells you that the signature is good and therefore you can trust the hashes in there. Now, running: md5sum -c livedvd-amd64-multilib-20121221.iso.DIGESTS.asc should show: livedvd-amd64-multilib-20121221.iso: OK for the iso image. Any files listed in the DIGESTS file which you have not downloaded or saved in the same directory, will be shown as FAILED, e.g. md5sum: livedvd-amd64-multilib-20121221.iso.CREDITS: No such file or directory livedvd-amd64-multilib-20121221.iso.CREDITS: FAILED open or read This is all explained here: http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1&chap=2 Hope this helps. -- Regards, Mick
