Choose Y here to enable Secure RPC using the Kerberos version 5
|
|
GSS-API mechanism (RFC 1964).
|
|
|
|
Secure RPC calls with Kerberos require an auxiliary user-space
|
|
daemon which may be found in the Linux nfs-utils package
|
|
available from http://linux-nfs.org/. In addition, user-space
|
|
Kerberos support should be installed.
|
|
|
|
If unsure, say Y.

help
|
|
Choose Y here to disable the use of deprecated encryption types
|
|
with the Kerberos version 5 GSS-API mechanism (RFC 1964). The
|
|
deprecated encryption types include DES-CBC-MD5, DES-CBC-CRC,
|
|
and DES-CBC-MD4. These types were deprecated by RFC 6649 because
|
|
they were found to be insecure.
|
|
|
|
N is the default because many sites have deployed KDCs and
|
|
keytabs that contain only these deprecated encryption types.
|
|
Choosing Y prevents the use of known-insecure encryption types
|
|
but might result in compatibility problems.

|

This option enables a sysctl-based debugging interface
|
|
that is be used by the 'rpcdebug' utility to turn on or off
|
|
logging of different aspects of the kernel RPC activity.
|
|
|
|
Disabling this option will make your kernel slightly smaller,
|
|
but makes troubleshooting NFS issues significantly harder.

If unsure, say Y.

This option allows the NFS client and server to use RDMA
|
|
transports (InfiniBand, iWARP, or RoCE).
|
|
|
|
To compile this support as a module, choose M. The module
|

will be called rpcrdma.ko.
|
|
|
|
If unsure, or you know there is no RDMA capability on your
|
|
hardware platform, say N.
