freebsd-questions: I have a computer: dpchrist@freebsd:/usr/home/dpchrist $ freebsd-version 11.0-RELEASE-p7 dpchrist@freebsd:/usr/home/dpchrist $ uname -a FreeBSD freebsd 11.0-RELEASE-p1 FreeBSD 11.0-RELEASE-p1 #0 r306420: Thu Sep 29 03:40:55 UTC 2016 root@releng2.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC i386 I periodically create archive files on Debian 7, encrypt the archive, create checksum files, burn the archive and checksum files to optical disc, and then verify the contents of the disc. The checksums verify okay on Debian 7. But when I put the optical disc into the subject FreeBSD computer and browse to it using Xfce and Thunar, the first thing I notice is that the archive file is listed twice: dpchrist@freebsd:/media/HOLGERDANSKE_COM $ ll total 8388607 drwxr-xr-x 1 root wheel - 2048 Feb 9 11:05 ./ drwxr-xr-x 3 root wheel uarch 5 Feb 9 14:34 ../ -rw-r--r-- 1 root wheel - 4294965248 Feb 9 08:52 201701.tar.cpt -rw-r--r-- 1 root wheel - 4294965248 Feb 9 08:52 201701.tar.cpt -rw-r--r-- 1 root wheel - 49 Feb 9 08:52 201701.tar.cpt.md5 -rw-r--r-- 1 root wheel - 81 Feb 9 08:52 201701.tar.cpt.sha256 When I attempt to verify the checksums, they fail: dpchrist@freebsd:/media/HOLGERDANSKE_COM $ cat 201701.tar.cpt.md5 dd2dfc838c03a1819efceab530a6c7f8 *201701.tar.cpt dpchrist@freebsd:/media/HOLGERDANSKE_COM $ md5 -c dd2dfc838c03a1819efceab530a6c7f8 201701.tar.cpt MD5 (201701.tar.cpt) = ac49e95889f44adbdaa2f68f4d7bb96e [ Failed ] dpchrist@freebsd:/media/HOLGERDANSKE_COM $ cat 201701.tar.cpt.sha256 87b0ba7ed7e706f55f571ec73daad0a2ab9820de9db8e0c889ba8541b5b8f40e *201701.tar.cpt dpchrist@freebsd:/media/HOLGERDANSKE_COM $ sha256 -c 87b0ba7ed7e706f55f571ec73daad0a2ab9820de9db8e0c889ba8541b5b8f40e 201701.tar.cpt SHA256 (201701.tar.cpt) = 10ebce65e89144fe6161b96a43920cf3437a18b34f1e92c7941343fa9a950ad3 [ Failed ] I suspect that FreeBSD is having problems because the archive file is larger than 4 GB (?). Any comments or suggestions? TIA, David
