put 'search the.dyndns.domain' into your resolv.conf


Thanks. Works, but it requires that the 'dynalias.org' part stays
fixed, and that I use it for all hosts I want to access via single
word hostnames. I'd still be curious about a more general solution to
do aliasing.

You can put several domains on the 'search ...' line. Obviously the
first match will win. See 'man resolv.conf' for details.

I know. The problem is that if there are several hosts with different
domains / subdomains, there will be needless lookups, wasting time and
bandwidth (perhaps not a lot of it, but still). Even worse, say I
control 'foo.dynalias.org' and 'bar.dyndns.org', but someone else
controls 'foo.dyndns.org' and 'bar.dynalias.org'. Then regardless of
which subdomain is first in 'resolv.conf', I'll get incorrect matches,
which is obviously totally unacceptable. At this point, I have various
workarounds for my needs (so far I only need ssh anyway, so I can just
use ssh aliasing, as in my earlier posts), but I'm still really curious
about a general, reasonably elegant solution.
