After upgrading to 10.1, one of the cronjobs here started to generate (and e-mail) a warning: socket: Address family not supported by protocol family The warning comes from crypto/openssh/sshconnect.c and the attached patch shuts it off. It seems necessary to patch the imported source (of OpenSSH), but I can't think of another way to do it properly... Maybe, the resolver should not return the AAAA-records on non-INET6 systems, but that seems bogus: the records exist and the resolver ought to return them without trying to foresee, how the caller might (mis)use them. Please, review the attached patch. It changes the existing if into a switch making it easier to #ifdef individual options later (some day we might have a NO_INET4 option). -- You are receiving this mail because: You are the assignee for the bug.
