|
NetRestrict - Defines interfaces not to register with AFS servers
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
There are two F<NetRestrict> files, one for an AFS client and one for an
|
|
AFS File Server or database server. The AFS client F<NetRestrict> file
|
|
specifies the IP addresses that the client should not register with the
|
|
File Servers it connects to. The server F<NetRestrict> file specifies
|
|
what interfaces should not be registered with AFS Database Servers or used
|
|
to talk to other database servers.
|
|
|
|
=head2 FORMAT
|
|
|
|
The F<NetRestrict> file is in ASCII format. One IP address appears on each
|
|
line, in dotted decimal format. The order of the addresses is not
|
|
significant. There is currently no mechanism to specify a range of
|
|
addresses or a wildcard; each IP address must be listed individually.
|
|
|
|
=head2 Client NetRestrict
|
|
|
|
The F<NetRestrict> file, if present in a client machine's F</usr/vice/etc>
|
|
directory, defines the IP addresses of the interfaces that the local Cache
|
|
Manager does not register with a File Server when first establishing a
|
|
connection to it. For an explanation of how the File Server uses the
|
|
registered interfaces, see L<NetInfo(5)>.
|
|
|
|
As it initializes, the Cache Manager constructs a list of interfaces to
|
|
register, from the F</usr/vice/etc/NetInfo> file if it exists, or from the
|
|
list of interfaces configured with the operating system otherwise. The
|
|
Cache Manager then removes from the list any addresses that appear in the
|
|
F<NetRestrict> file, if it exists. The Cache Manager records the resulting
|
|
list in kernel memory.
|
|
|
|
The F<NetRestrict> file is in ASCII format. One IP address appears on each
|
|
line, in dotted decimal format. The order of the addresses is not
|
|
significant.
|
|
|
|
To display the addresses the Cache Manager is currently registering with
|
|
File Servers, use the B<fs getclientaddrs> command.
|
|
|
|
=head2 Server NetRestrict
|
|
|
|
The F<NetRestrict> file, if present in the F</usr/afs/local> directory,
|
|
defines the following:
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
On a file server machine, the local interfaces that the File Server
|
|
(B<fileserver> process) does not register in the Volume Location Database
|
|
(VLDB) at initialization time.
|
|
|
|
=item *
|
|
|
|
On a database server machine, the local interfaces that the Ubik
|
|
synchronization library does not use when communicating with the database
|
|
server processes running on other database server machines.
|
|
|
|
=back
|
|
|
|
As it initializes, the File Server constructs a list of interfaces to
|
|
register, from the F</usr/afs/local/NetInfo> file if it exists, or from
|
|
the list of interfaces configured with the operating system otherwise. The
|
|
File Server then removes from the list any addresses that appear in the
|
|
F<NetRestrict> file, if it exists. The File Server records the resulting
|
|
list in the F</usr/afs/local/sysid> file and registers the interfaces in
|
|
the VLDB. The database server processes use a similar procedure when
|
|
initializing, to determine which interfaces to use for communication with
|
|
the peer processes on other database machines in the cell.
|
|
|
|
To display the File Server interface addresses registered in the VLDB, use
|
|
the B<vos listaddrs> command.
