According to the FAQ, I think 192.168.1 represents the network 192.168.1.0.
http://www.openbsd.org/faq/faq6.html#NFS <http://www.openbsd.org/faq/faq6.html#NFS> The IP of Mac is 192.168.1.36. And the IP of server is 192.168.1.1. If I run showmount on Mac, I get these: $ showmount -e 192.168.1.1 Exports list on 192.168.1.1: /nfs 192.168.1.0 Here is what I found in manual of mount_nfs on Mac: nfsvers=<num> Set the NFS protocol version number - 2 for NFSv2, 3 for NFSv3 and 4 for NFSv4. The default is to try version 3 first, and fall back to ver- sion 2 if the mount fails.
