Perfect -- that's exactly the sort of detail it's great to have in man-pages!

I dug a little further comparing versions 2.0.6 [1], 2.0.7 [2] and trunk [3] of glibc and I come to a different conclusion. The keywords nospoof, spoofalert, spoof and RESOLV_SPOOF_CHECK were added to glibc 2.0.7 but never implemented and documented in the changelog.

Best to keep a note that they exist, but do nothing.

It appears that you (and the reporter) are correct. (Even back in glibc 2.1, things look the same). A patch would be appreciated! Cheers, Michael PS For reports like this, when you've checked things, it would speed things a little to note how you deduced your info (e.g., reference to source file and function). > > [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=773443 -- Michael Kerrisk Linux man-pages maintainer; http://www.kernel.org/doc/man-pages/ Linux/UNIX System Programming Training: http://man7.org/training/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
