I have an NFS server (CentOS 6.6 at IP 192.168.1.16) that shares a folder /nfs/share.
I want to mount this folder from a Mac laptop (at mount point /nfs/share).
When I tried the following:
sudo mount -t nfs -o rw,sync,resvport 192.168.1.16:/nfs/share /nfs/share/
(both with or without 'resvport' option) I got an error:
mount_nfs: can't mount /nfs/share from 192.168.1.16 onto /nfs/share: Connection refused
The NFS server should be properly configured as I have no problem mounting the share from a CentOS computer.
The content of /etc/exports looks like this:
/nfs/share 192.168.1.1/24(rw,sync)
UPDATE: finally found that on the NFS server /etc/exports, I need to add insecure as an option:
/nfs/share 192.168.1.1/24(rw,sync,insecure)
Apparently this is needed to allow Mac OS X client to connect and according to some it's "not otherwise insecure" but others have claimed that it should not be used.
