Exactly - ditto for gethostbyname(). In the case of gethostbyname(),
I believe that domain names can't have a number as the first
character - I would have thought this idea should follow through with
services.
I know I'd be pretty annoyed if I tried to do something like ``ssh -p
1234 somewhere'' after configuring my interface in single-user modem
with nis in /etc/host.conf and found that ssh was looking up 1234 in
/etc/services. Even if this is right, it's not intuitive.
