Can you provide information on what OS and or distribution this happens? > is in the RFC a Part of IPv6 why not making IPv6 default and mapping > IPv4 requests in it ? getaddrinfo is supposed to do exactly this. But this will only work on hybrid IPv4/IPv6 stacks. On systems where the stacks are separate, the feature is disabled or not implemented at all you will get a a socket listening on one address family. This is only an issue with in6addr_any, e.g. no server_address was configured. The correct and portable solution for this seems to be listening on two sockets one for INADDR_ANY (IPv4) and one for in6addr_any (IPv6). I have to read up on the details on how this works. But I expect it to be a total pain in the ass. For completeness sake I'm probably going to implement it. One could always run the daemon from inetd and only use the patched check_nrpe binary. (There is the second issue of getaddrinfo being a superset of what the original nrpe does: One can now configure a name for server_address but one will only get one listening socket. I'm not going to address this issue because server_address is supposed to be an address if provided. I would consider raising an error if a name is configure if I can figure out how to do this). > > Regards, > > Mike > ------------------------------------------------------------------------------ Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
