HostnameLookups do not work with Apache 2.0





------- Additional Comments From trawick@apache.org  2003-06-23 02:37 -------
works for me on RedHat 9, and nobody else has mentioned this issue as far as I
recall

one difference between Apache 1.3's support for this and Apache 2.0's is that
Apache 2.0 uses getnameinfo() for looking up client hostname instead of
gethostbyaddr()

stuff to try:

a) in case you have IPv6 active on your box, switch Apache to IPv4 with
something like this:

Listen 0.0.0.0:80

instead of

Listen 80

this is to see if your getnameinfo() is fooled by v4-mapped address

b) add some tracing around the call to getnameinfo()?

it *sounds* like getnameinfo() on your system is not respecting the NI_NAMEREQD
that we pass in

c) disable use of getnameinfo()

need to do 3 things, I suspect:

0) make distclean
1) add --disable-ipv6 to configure invocation
2) after configure completes but before you run make, edit
srclib/apr/include/arch/unix/apr_private.h and comment out the line "#define
HAVE_GETNAMEINFO 1" to see if it works when gethostbyaddr() is used
