Hi All.

I built some jail() in my system, and connect each other / from base system.
So I added pair of IP address - hostname into /etc/hosts as below
Code:
...
fd00::ffff:10.0.0.3   ssh.example.com
10.0.0.3              ftp.example.com
...
Tried by ftp ftp.example.com and got result as below.
Code:
Trying 10.0.0.3:21 ...
Connected to ftp.example.com.
IPv6 connection only if IPv4 address invalid (10.9.9.9 instead) as below.
Code:
Trying 10.9.9.9:21 ...
ftp: Can't connect to `10.9.9.9:21': Permission denied
Trying fd00::ffff:a00:203:21 ...
Resolver always use IPv4 address, even line swap in /etc/hosts.
Can I modify to preferred IPv6 address?

Note :
  • Ports (MySQL client) same behavior.
  • ip6addrctl() had been configure /etc/rc.conf.d/ip6addrctl as below
    Code:
    ip6addrctl_enable="YES"
    ipv6_activate_all_interfaces="YES"              # The configuration let "ipv6_prefer"
Thanks all very much:)
