sfsrwsd_config - file server configuration
Set the Location part of the server’s self-certifying pathname.
The default is the current host’s fully-qualified hostname.
Tells sfsrwsd to look for its private key in file path. The
default is sfs_host_key. SFS looks for file names that do not
start with / in /etc/sfs, or whatever directory you specified if
you used the -with-etcdir option to configure ().
Export local-directory sfs-name [R|W]
Tells sfsrwsd to export local-directory, giving it the name sfs-
name with respect to the server’s self-certifying pathname.
Appending R to an export directive gives anonymous users read-only
access to the file system under the anonymous user group IDs
specified in sfs_config. (See the description of the anonuser
directive in the sfs_config man page for more information .)
Appending W gives anonymous users both read and write access. See
the Quick server setup section of the SFS info pages for an example
of the Export directive.
There is almost no reason to use the W flag. The R flag lets
anyone on the Internet issue NFS calls to your kernel as the
anonymous user. SFS filters these calls; it makes sure that they
operate on files covered by the export directive, and it blocks any
calls that would modify the file system. This approach is safe
given a perfect NFS3 implementation. If, however, there are bugs
in your NFS code, attackers may exploit them if you have the R
option--probably just crashing your server but possibly doing
Specifies the amount of time for which SFS clients can cache file
attributes. During this period, if a file is modified, the server
will call back to the client to let it know that the file’s
attributes have changed. Unfortunately, if a file is modified not
through SFS (e.g., through the local file system interface on the
server), the server may not realize the attributes have changed,
and clients may see stale data for the lease period. The default
lease term is 60 seconds.
