Cant connect IPv6 linux server via Putty. Server IP should be like this: 2001:14c0:2:2f6f::6

But when i replace working IPv4 in my putty by this address, it dont connect returning: Unable to open connection to MYIPv6 Host does not exist

Please which files to check, commands to do to make IPv6 ssh connection working?


In /etc/sysconfig/network-scripts ssh config, I have:

Port 22
AddressFamily any
ListenAddress 0.0.0.0
ListenAddress ::

ping6 ipv6.google.com works

ping myipv6::6 works too

ping myipv6::1 works too (received, no packet loss)

traceroute6 google.com works too

You have a routing problem at your end, according to ping6 and traceroute6. Post your complete IPv6 configuration, and the details of what the configuration is meant to be. –  Michael Hampton Oct 5 '13 at 18:21

You should input the IPv6 address between brackets, like this:

[2001:14c0:2:2f6f::6]

then it will work.
