Don't know why the sums are inconsistent, but it may indicate that something has changed in the files. BTW, should you still be using md5sum for this? MD5 is no longer considered a secure hash algorithm, with examples of two or more different files generating the same MD5 hash available. [ http://en.wikipedia.org/wiki/MD5 ] You should migrate to SHA1/SHA256, etc. Regards, Kam Yung -- Soh Kam Yung my Google Reader Shared links: (http://www.google.com/reader/shared/16851815156817689753) my Google Reader Shared SFAS links: (http://www.google.com/reader/shared/user/16851815156817689753/label/sfas) _______________________________________________ LUGS Mailing list - [email protected] List FAQ: http://wiki.lugs.org.sg/LugsMailingListFaq Info page: http://www.lugs.org.sg/mailman/listinfo/slugnet To unsubscribe send an empty email to: [email protected]
