Hi, >>>>> On Sun, 26 Feb 2006 22:56:32 +0200 >>>>> Rostislav Krasny <rosti.bsd@gmail.com> said: rosti> Could you please suggest a good rosti> comprehensive article on the Web about IPv4-mapped IPv6 addresses and rosti> their usage? You can find some documents by googling with `IPv4-mapped IPv6 address'. In addition, you should read RFC 4038: http://www.ietf.org/rfc/rfc4038.txt?number=4038 rosti> By the way, why you don't do the address type test in a rosti> daemon mode of ftpd? Because, ftpd(8) in daemon mode doesn't accept an IPv4 using an IPv4-mapped IPv6 address by issuing the IPV6_V6ONLY socket option. Please refer socksetup(). In inetd mode, enable/disable use of an IPv4-mapped IPv6 address is depending on how to configure inetd.conf. So, we need to pay attention to an IPv4-mapped IPv6 address in inetd mode.
