This list again worked with amazing speed. The first answer arrived
after 15 minutes and resolved my problem.

The solution: use the tcp wrapper adapted by Casper Dik at

        ftp://playground.sun.com/pub/casper/
        ftp://ftp.porcupine.org/pub/ipv6

Advantages over the other implementations:

        - uses modern RFCxxxx IPv6 interfaces
        - single binary for IPv6 and IPv4
        - same syntax for /etc/hosts.{allow,deny} as before
        - extended hosts.{allow,deny} syntax that allows Ipv6 addresses
          and networks.
        - binary compatible libwrap (not tested, but believed to be
          true)
        - Works on Solaris 8
        - May work on AIX (not tested)

Other suggestion:
        - try xinetd, at www.xinetd.org

Does anybody have any clue where I can find a tcp wrapper that will
work with IPv4 and IPv6 on Solaris 8?

I have tried to find IPv6 enabled tcp wrappers, but found nothing that
will work on Solaris 8.
The two IPv6 enabled tcp wrappers I found are:
KAME (a diff listing)
        This uses gethostbyname2. This call is not supported on Solaris 8.
        SUN replaced gethostbyname by the newer getaddrinfo. I tried making
        a gethostbyname2 stub, but got bogged down in the internals
        of the IPv6 enabled TCP wrapper.
tcp_wrapper_7.6+ipv6-1
        - also uses gethostbyname2
        - it seems to be LINUX-only.
        - it uses different format for the allow and deny files. This makes
          it a less attractive solution.
