Provides kernel support for querying rpcbind servers via versions 3
|
||||
and 4 of the rpcbind protocol. The kernel automatically falls back
|
||||
to version 2 if a remote rpcbind service does not support versions
|
||||
3 or 4.
|
||||
RPC requests over IPv6 networks require support for larger
|
||||
addresses when performing an RPC bind. Sun added support for
|
||||
IPv6 addressing by creating two new versions of the rpcbind
|
||||
protocol (RFC 1833).
|
||||
|
||||
This option enables support in the kernel RPC client for
|
||||
querying rpcbind servers via versions 3 and 4 of the rpcbind
|
||||
protocol. The kernel automatically falls back to version 2
|
||||
if a remote rpcbind service does not support versions 3 or 4.
|
||||
By themselves, these new versions do not provide support for
|
||||
RPC over IPv6, but the new protocol versions are necessary to
|
||||
support it.
|
||||
|
||||
If unsure, say N to get traditional behavior (version 2 rpcbind
|
||||
requests only).
