Description ganesh 1999-05-24 05:12:48 UTC 
mountd doesn't like IP addresses which it cant reverse
lookup ?
e.g. I have a private IP which is not in DNS and I want
it to mount a directory hosted on RH6.0 (on an ultra5).
this directory has been globally exported.
but I get permission denied on the client and
/var/log/messages contains
May 24 09:58:16 mira mountd[764]: mount request from unknown
host 192.168.101.20
paranoia is all very nice, but this is silly.
I've tried lines like
/export/home	192.168.0.0/16(ro)
but it just doesnt work. still the same problem.
then I added
192.168.101.20	janus.vxindia.veritas.com janus
to /etc/hosts
and now it says
May 24 10:37:03 mira mountd[1071]: refused mount request
from janus.vxindia.veritas.com: no export entry
*sigh* got me coming and going.
now I change /etc/exports to
/export/home	(ro)
and NOW it works.

and /etc/rc.d/init.d/nfs restart doesn't work.
HUP winds up killing half the daemons. stop and start
work sometimes. sometimes nfsd doesn't stop/start properly,
inspite of unloading/reloading all relevant modules.
May 24 09:50:28 mira rpc.nfsd: nfssvc: Address already in
use
(I'll try to get a reproducible case and report separately)

I just upgraded knfsd to 1.3.3 which includes this line:

Changes from knfsd 1.3.2:
1. Modified mountd to allow clients without IP address to hostname
map.

Please reopen this bug if knfsd-1.3.3-1 does not fix.
