To use the Secure NFS system, all the computers that you are responsible for must have a domain name. Typically, a domain is an administrative entity of several computers that is part of a larger network. If you are running a name service, you should also establish the name service for the domain. See System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP).
Kerberos V5 authentication is supported by the NFS service. Chapter 21, Introduction to the Kerberos Service, in System Administration Guide: Security Services discusses the Kerberos service.
You can also configure the Secure NFS environment to use Diffie-Hellman authentication. Chapter 16, Using Authentication Services (Tasks), in System Administration Guide: Security Services discusses this authentication service.
See the System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP) if you are using NIS+ as your name service.
If you are running NIS+, type the following:
# nisping -u Last updates for directory eng.acme.com. : Master server is eng-master.acme.com. Last update occurred at Mon Jun 5 11:16:10 1995 Replica server is eng1-replica-replica-58.acme.com. Last Update seen was Mon Jun 5 11:16:10 1995
If you are running NIS, verify that the ypbind daemon is running.
Type the following command.
# ps -ef | grep keyserv root 100 1 16 Apr 11 ? 0:00 /usr/sbin/keyserv root 2215 2211 5 09:57:28 pts/0 0:00 grep keyserv
Usually, the login password is identical to the network password. In this situation, keylogin is not required. If the passwords are different, the users have to log in, and then run keylogin. You still need to use the keylogin -r command as root to store the decrypted secret key in /etc/.rootkey.
Note - You need to run keylogin -r if the root secret key changes or if /etc/.rootkey is lost.
share -F nfs -o sec=dh /export/home
See the dfstab(4) man page for a description of /etc/dfs/dfstab.
/home auto_home -nosuid,sec=dh
Note - Releases through Solaris 2.5 have a limitation. If a client does not securely mount a shared file system that is secure, users have access as nobody rather than as themselves. For subsequent releases that use version 2, the NFS server refuses access if the security modes do not match, unless -sec=none is included on the share command line. With version 3, the mode is inherited from the NFS server, so clients do not need to specify sec=dh. The users have access to the files as themselves.
When you reinstall, move, or upgrade a computer, remember to save /etc/.rootkey if you do not establish new keys or change the keys for root. If you do delete /etc/.rootkey, you can always type the following:
# keylogin -r
