The NFSv4.1 client can be enabled to be a direct participant in the exact location of file data and to avoid solitary interaction with one NFS server when moving data. In addition to pNFS, NFSv4.1 provides: Sessions; Directory Delegation and Notifications; Multi-server Namespace; access control lists and discretionary access control; Retention ...
Usually, Transport Layer Security (TLS) uses public key certificates or Kerberos for authentication. TLS-PSK uses symmetric keys, shared in advance among the communicating parties, to establish a TLS connection. There are several reasons to use PSKs: Using pre-shared keys can, depending on the ciphersuite, avoid the need for public key operations.
Richacls is a Linux implementation of the NFSv4 ACLs which has been extended by file masks to more easily fit the proprietary POSIX draft file permission model. [1] Nowadays, they offer the most complex permission model for ext4 file system in Linux. They are even more complex than POSIX draft ACLs, which means it is not possible to convert ...
In some computer security systems, a Ticket Granting Ticket or Ticket to Get Tickets (TGT) is a small, encrypted identification file with a limited validity period. After authentication, this file is granted to a user for data traffic protection by the key distribution center (KDC) subsystem of authentication services such as Kerberos.
In most (but not all) cases the KDC shares a key with each of all the other parties. The KDC produces a ticket based on a server key. The client receives the ticket and submits it to the appropriate server. The server can verify the submitted ticket and grant access to user submitting it.
a Kerberos realm name; an Active Directory domain name; the name of an operating-system vendor (for distribution-specific allocations) the name of a computer (for device-specific allocations) But in practice many existing implementations only allow setting the NFSv4 domain to a fixed value, thereby rendering it useless.
