Hello,
I wanted to shorten writing some often used addresses like
penelopa.karlov.mff.cuni.cz
e.g. in a scp command. I want to only have to write penelopa.
So I added
sys = penelopa
dom=penelopa.karlov.mff.cuni.cz
to /lib/ndb/local
But that doesn't help. What's missing?
Thanks
Ruda

an ip address. also the spaces around the '='
mean that ndb will fail to see sys/penelopa
as a key/value pair.
since there is no ip address, dns is used.
and you have to use the long-form address.

Well. The ip address is not specified because it could possibly change.
However, removing the spaces around = helped.
Btw. I saw the spaces in 'The Organization of Networks in Plan9' by
Presotto & Winterbottom, part 4.1. on page 8, see 'sys = helix'. So
there it is probably wrong...
Thanks!

If you don't want to wire down ip addresses in ndb:
penelopa = penelopa.karlov.mff.cuni.cz
and use $penelopa in your commands.

It finally works without any IP mentioned. Only the surrounding spaces
were the problem, otherwise my entry works as it was written in the
beginning...

For the record, you may find CNAMEs workable too. Although CNAMES
are restrictive, they are propagated to other OS platforms which is
not the case, at least to the extent that I have tried them, for SYS
entries in NDB.
