I have a first quick and dirty patch, replacing AF_INET by AF_INET6, the sockaddr_in structs and so on. I think it is broken, the calculation of net1 and net2 in btl_tcp_proc.c isn't really ported and to be honest: I don't understand the details, i.e. do I have to port name lookups, are there high level structures relying on IPv4 structs and so on. At least it compiles ;) (let's ship it) I don't know if this patched tcp-component can handle IPv6 connections, I've never tested it. I think it even breaks IPv4 functionality; we should make clear how IPv4 and IPv6 may work in parallel (or may not, if one considers IPv4 deprecated ;) You can retrieve the patch here: http://cluster.inf-ra.uni-jena.de/~adi/ompi.ipv6.v1.patch I'd also appreciate any suggestions, hints or even success stories ;) -- mail: a...@thur.de http://adi.thur.de PGP: v2-key via keyserver Bill Gates's Motto: "If you can't make it good, make it look good!"
