NAME

fs exportafs - Configures export of AFS to clients of other file systems

SYNOPSIS

fs exportafs -type <exporter name> [-start <start/stop translator (on | off)>] [-convert <convert from afs to unix mode (on | off)>] [-uidcheck <run on strict 'uid check' mode (on | off)>] [-submounts <allow nfs mounts to subdirs of /afs/.. (on | off)>] [-help]

fs exp -t <exporter name> [-st <start/stop translator (on | off)>] [-c <convert from afs to unix mode (on | off)>] [-u <run on strict 'uid check' mode (on | off)>] [-su <allow nfs mounts to subdirs of /afs/.. (on | off)>] [-h]

DESCRIPTION

The fs exportafs command sets (if the -start argument is provided) or reports (if it is omitted) whether the machine can reexport the AFS filespace to clients of a non-AFS file system. To control certain features of the translation protocol, use the following arguments:

OPTIONS

-type <exporter name>

Names the alternate file system to which to reexport the AFS filespace. The only acceptable value is nfs, in lowercase letters only.

-start on =item -start off

Enables the local machine to reexport the AFS filespace if the value is on, or disables it if the value is off. Omit this argument to report the current setting for all of the configurable parameters.

-convert on =item -convert off

Controls the setting of the UNIX group and other mode bits on AFS files and directories exported to the non-AFS file system. If the value is on, they are set to match the owner mode bits. If the value is off, the bits are not changed. If this argument is omitted, the default value is on.

-uidcheck on =item -uidcheck off

Controls whether tokens can be placed in a credential structure identified by a UID that differs from the local UID of the entity that is placing the tokens in the structure.

-submounts on =item -submounts off

Controls whether a user of the non-AFS filesystem can mount any directory in the AFS filespace other than the top-level /afs directory. If the value is on, such submounts are allowed. If the value is off, only mounts of the /afs directory are allowed. If this argument is omitted, the default value is off.

-help

Prints the online help for this command. All other valid options are ignored.

OUTPUT

If the machine is not even configured as a server of the non-AFS file system, the following message appears:

   Sorry, the <file_system>-exporter type is currently not supported on
   this AFS client

If the machine is configured as a server of the non-AFS file system but is not currently enabled to reexport AFS to it (because the -start argument to this command is not set to on), the message is as follows:

   '<file_system>' translator is disabled

If the machine is enabled to reexport AFS, the following message precedes messages that report the settings of the other parameters.

   '<file_system>' translator is enabled with the following options:

The following messages indicate that the -convert argument is set to on or off respectively:

   Running in convert owner mode bits to world/other mode
   Running in strict unix mode

The following messages indicate that the -uidcheck argument is set to on or off respectively:

   Running in strict 'passwd sync' mode
   Running in no 'passwd sync' mode

The following messages indicate that the -submounts argument is set to on or off respectively:

   Allow mounts of /afs/.. subdirs
   Only mounts to /afs allowed

EXAMPLES

The following example shows that the local machine can export AFS to NFS client machines.

   % fs exportafs nfs
   'nfs' translator is enabled with the following options:
        Running in convert owner mode bits to world/other mode
        Running in no 'passwd sync' mode
        Only mounts to /afs allowed

The following example enables the machine as an NFS server and converts the UNIX group and other mode bits on exported AFS directories and files to match the UNIX owner mode bits.

   % fs exportafs -type nfs -start on -convert on

The following example disables the machine from reexporting AFS to NFS client machines:

   % fs exportafs -type nfs -start off
