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