System: NetBSD setting-sun.duskware.de 1.5W NetBSD 1.5W (SETTINGSUN) #0: Mon Jul 16 23:54:59 MEST 2001 martin@setting-sun.duskware.de:/usr/src/sys/arch/sparc64/compile/SETTINGSUN sparc64

>Description:

My machine is IPv4 only (no option INET6 in the kernel config).
When I try to ssh or scp to ftp.netbsd.org, I get a spurious warning

socket: Protocol not supported

The connection works, nevertheless. I suppose it's trying all addresses it got
back from the nameserver, where the IPv6 one fail and cause this warning.

>How-To-Repeat:
s/a

>Fix:
Not sure:
Fix the resolver routines to remove IPv6 replies when running on IPv4 only machines?
Make ssh/scp not complain as long as at least one address works?
