Autofs consults the master map configuration file /etc/auto.master to determine which mount points are defined. Logic pro x 10 2 1. It then starts an automount process with the appropriate parameters for each mount point. Each line in the master map defines a mount point and a separate map file that defines the file systems to be mounted under this mount point.
Direct maps in
autofs
provide a mechanism to automatically mount file systems at arbitrary points in the file system hierarchy. A direct map is denoted by a mount point of /-
in the master map. Entries in a direct map contain an absolute path name as a key (instead of the relative path names used in indirect maps). - See the comments in /etc/autofs/auto.smb. FTP and SSH (with FUSE) Remote FTP and SSH servers can be accessed seamlessly with AutoFS using FUSE, a virtual file system layer. First, install the curlftpfs package. Load the fuse module: # modprobe fuse Create a /etc/modules-load.d/fuse.conf file containg fuse to load it on each system boot.
- Since autofs doesn't work particularly well with SSH public key authentication (unless you want to create a passwordless key pair for the superuser), there are tools that allow you to use the user's SSH keys, ssh-agent and keychain.
- Auto Mounting SFTP / SSH in Ubuntu (SSHFS / FUSE / AUTOFS) Sorry for the geek post, but I wanted to share this because it took me a while to get this right. In my first foray into eLance, I had a programmer / scripter convert a tutorial on using SSHFS, Fuse and AutoFS to auto-mount SFTP/SSH connections in Ubuntu into a single, easy to use Bash.

Multi-mount map entries describe a hierarchy of mount points under a single key. A good example of this is the
-hosts
map, commonly used for automounting all exports from a host under '/net/host
' as a multi-mount map entry. When using the '-hosts
' map, an 'ls
' of '/net/host
' will mount autofs
trigger mounts for each export from host
and mount and expire them as they are accessed. This can greatly reduce the number of active mounts needed when accessing a server with a large number of exports. The Lightweight Directory Access Protocol (LDAP) support in
autofs
version 5 has been enhanced in several ways with respect to autofs version 4. The autofs
configuration file (/etc/sysconfig/autofs
) provides a mechanism to specify the autofs
schema that a site implements, thus precluding the need to determine this via trial and error in the application itself. In addition, authenticated binds to the LDAP server are now supported, using most mechanisms supported by the common LDAP server implementations. A new configuration file has been added for this support: /etc/autofs_ldap_auth.conf
. The default configuration file is self-documenting, and uses an XML format. Autofs Fstype Options
nsswitch
) configuration. The Name Service Switch configuration file exists to provide a means of determining from where specific configuration data comes. The reason for this configuration is to allow administrators the flexibility of using the back-end database of choice, while maintaining a uniform software interface to access the data. While the version 4 automounter is becoming increasingly better at handling the NSS configuration, it is still not complete. Autofs version 5, on the other hand, is a complete implementation.
Refer to

One thing that is frequently used but not yet mentioned is the handling of multiple master map entries for the direct mount point
