My memory is that if you only list IP addresses in /etc/exports then it will do just want you want. But if you list any host names or net groups then it has to do a DNS lookup on everything to see if either of those matches. > > In Changelog: > > 2001-09-20 NeilBrown <neilb@xxxxxxxxxxxxxxx> > Anne Milicia <milicia@xxxxxxxxxxxxxxxxxxxxxxxx> > > * support/export/client.c (client_lookup) call gethostbyadd > to make sure that we have a canonical hostname, even for > dotted-quads I think this patch only related to netgroup lookups. > > Why does mountd need to repeat the gethostbyname() lookup on every host > even though exportfs already converted over to using hostname? exportfs doesn't convert over host hostnames. It essentially copies /etc/exports to /var/lib/nfs/etab with minor formatting changes. What do you actually put in /etc/exports, what do you find in /var/lib/nfs/etab, and what exactly is the problem?
