I think this patch broke test-linc on multihomed hosts. I have tested only on Win32, but assume the same can happen on Unix. The scenario, as I see it, is as follows:
- get_netid() looks up the interfaces of the machine, and chooses the address if the first non-loopback one it finds. - link_server_setup() creates a socket and binds it to this address. - link_server_setup() calls link_protocol_get_sockinfo() which calls link_protocol_get_sockinfo_ipv4(), which calls gethostbyaddr() on the address get_netid() returned. This returns a name for the machine. - create_client() then tries to connect to the server using the name looked up by link_protocol_get_sockinfo_ipv4(). Eventually link_protocol_get_sockaddr_ipv4() is called and it looks up this name. This however returns *another* one of the machine's addresses. Thus the connection fails. I.e. the problem is that the IP address get_netid() returns is not necessarily the one that looking up the address corresponding to the machine's name will return. The use of hostnames and/or IP addresses in linc2 seems quite mixed up and confusing. Couldn't we just stop using hostnames completely in ORBit2, and use only IP (v4 or v6) addresses in IORs etc? --tml _______________________________________________ orbit-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/orbit-list
