 The server is correct, this is a bug in the ftp(1) client on NetBSD.
 It has been fixed on all active branches some time ago.
 
 To work around it you need to manually update base.tgz once, e.g. when
 you see your above output, construct an absolute url from it:
 
   ftp -a http://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-9/202209281530Z/amd64/binary/base.tgz
 
 (note base, not kern.tgz), then extract that manually, like
 
   # cd / && tar xpzf /tmp/base.tgz
 
 and after that your new ftp(1) binary will work with the relative redirects.
 
 This is a safe thing to do on release branches at least, for -current
 you might want to do the same trick for kernel first (but there has
 been no userland relevant change in months, so it is almost safe in
 -current to).
