  • PuTTy IPv6

    From Christian H. Kuhn@21:1/5 to All on Thu Jan 26 10:13:35 2017
    Hi,

    PuTTy v0.67, Windows 10 (all updates), T-Online DSL-Account (provides
    IPv4 and IPv6 connectivity).

    ping ssh.qno.de and ping6 ssh.qno.de both find the appropriate address
    to ping, so name resolving seems to work fine.

    PuTTy connects to ssh.qno.de by IPv4 correctly.

    PuTTy does not connect by IPv6. Unable to open connection to ssh.qno.de gethostbyname: unknown error.

    Seems that PuTTy has some problems with name resolving. How can i fix it?

    TIA

    I don't have a Windows box with IPv6 connectivity, but a friend has successfully used PuTTY 0.67 (on Windows 7 Pro) to resolve and connect
    to a v6-only SSH server (with native IPv6 connectivity, not Teredo or anything). So it's not totally broken.

    The gethostbyname() function is deprecated. It cannot be used to return both IPv4 and IPv6 addresses. If an IPv4 address is defined for the specified hostname, that is the only address that gethostbyname() will return.

    gethostbyname() can only return IPv6 addresses if only IPv6 addresses are defined.

    gethostbyname() has been replaced by getaddrinfo() when it is available.
