NAME

        sfsrwsd_config - file server configuration
 

DESCRIPTION

        Hostname name
            Set the Location part of the server’s self-certifying pathname.
            The default is the current host’s fully-qualified hostname.
 
        Keyfile path
            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 speci‐
            fied 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 any‐
            one 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 per‐
            fect 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 worse.
 
        LeaseTime seconds
            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.

        The full documentation for SFS is maintained as a Texinfo manual.  If
        the info and SFS programs are properly installed at your site, the com‐
        mand info SFS should give you access to the complete manual.
