sfsrwsd_config(5)
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 path
- name. 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 informa
- tion .) 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 ap
- proach 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 worse.
- LeaseTime seconds
- Specifies the amount of time for which SFS clients can
- cache file attributes. During this period, if a file is modi
- fied, 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 in
- terface on the server), the server may not realize the attributes
- have changed, and clients may see stale data for the lease peri
- od. The default lease term is 60 seconds.
