Hi Nilotpal,
I tried following things: 1) Made socket() system call with AF_INET6 family type. 2) Made connect() system call to get connected to destination address using the socket created above. 3) Then made call to Bio_new_socket() and passed the connected socket descriptor. 4) Thereafter made call to Bio_set_nbio() and Bio_do_connect() on the socket BIO, and this time I got error from the Bio_do_connect() call. Though I have added diags if Bio_new_socket() call gets failed. But those diags were not getting hit. So, I am assuming that step 1 to step 3 are working fine. Problem is coming at the time of Bio_do_connect(). Now the next questions which come in my mind are: 1) Bio_set_nbio() and Bio_do_connect() API's are IPv6 compatible? 2) If yes, then what am I missing here because of which I am getting error from Bio_do_connect() API? 3) If no, then how can I proceed further because I need to use API which are both (IPv6 as well as IPv4) compatible. Please suggest. Thanks Akanksha Shukla.

Hi, You can try this once. Use socket library connect() to get the connected socket. Then use BIO_new_socket() and pass the connected socket descriptor. Then, on the socket BIO you can try BIO_set_nbio() and BIO_do_connect().

But I am still left with few queries: 1) From your reply, what I understood is that Bio_new_connect() doesn't support IPv6. But what about other two API's BIO_set_nbio() and BIO_do_connect() ??. Do these API's support IPv6? 2) Are there any OpenSSL API which can be used to work on both IPv4 as well as IPv6 so rather than using the legacy one which supports only IPv4. 3) Moreover my application is acting like a client server which will send request. So, I need such API's which has support over IPv6.

BIO_new_connect() (and BIO_get_host_ip() which it calls) only deal in IPv4 addresses. As far as I know, though, you should be able to make an IPv6 socket connection yourself, pass it to BIO_new_socket(), and have it work. It's just the hostname/address lookup that is address-family specific. (Oddly, the server side of things (accept() etc.) seems to have been extended to support IPv6 already.) ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org -- With regards, Nilotpal
