While running the SSH demon, only ssh for tcp is listening, tcp6 is not getting listened, even though sshd_config file contains both Ipv4 and Ipv6.

Due to this, ssh demon is not replying for ipv6 ssh.

netstat -l
tcp        0      0 *:ssh                   *:*                     LISTEN

netstat -nat
tcp        0      0 :::22                   :::*                    LISTEN

sshd_config file includes the follow,

ListenAddress ::

I have used the same sshd_config file in another linux desktop, there its listening for both ipv4 and ipv6.
