Hi Mihai, Most probably, you need the file named BUILDINFO, see for example these: https://ftp.openbsd.org/pub/OpenBSD/snapshots/amd64/BUILDINFO https://ftp.eu.openbsd.org/pub/OpenBSD/snapshots/amd64/BUILDINFO For scripting of course, replace 'amd64' with "$(arch -s)" or `arch -s`. Comparing these files between the main and local mirrors, and your local set of downloaded files could be a start in the direction you are going. Presumably that's validation of the snapshot build time between mirrors. Here is the current list of mirrors: https://www.openbsd.org/ftp.html However, to make sure you got all files, and these files are consistent, you could use cksum(1) to validate the check sums of the files you have. https://man.openbsd.org/cksum The FAQ describes well the process of validation checksums & signatures: https://www.openbsd.org/faq/faq4.html#Download And also important, you can re-read INSTALL.$(arch -s) in the files dir: https://ftp.eu.openbsd.org/pub/OpenBSD/snapshots/amd64/INSTALL.amd64 Kind regards, Anton Lazarov > Here is the thing: I can see the timestamps on > master site, ftp.openbsd.org (let's skip the transfer protocol, like > ftp, http/https). > Are these timestamps the original from compilation time?
