Autofs configuration
Autofs uses /etc/autofs/auto.master as its default primary configuration file. We can define two kind of maps in this file, direct and indirect. An example:
# mount point config file options
/- /etc/autofs/auto.direct --ghost
/media/cifs /etc/autofs/auto.cifs --timeout=60 --ghost
/media/sshfs /etc/autofs/auto.sshfs --timeout=60 --ghost
+auto.master
First map is a direct map, the other two are indirect. Entries in a direct map contain an absolute path, instead of the relative path names used in indirect maps. The --ghost option tells the automounter to create empty directories of all the mount points. The /media folder should be empty. Let's see the other configuration files, in this example we are going to mount a remote file system using cifs and ssh.
/etc/autofs/auto.direct
# directory mount options device to mount
/home/ian/music -fstype=cifs,ro,soft,user=guest ://192.168.1.10/music
/home/deb/music -fstype=cifs,ro,soft,user=guest ://192.168.1.10/music
Folders /home/ian/music and /home/deb/music should be empty or not exist. In both we can access to te remote folder /music in computer 192.168.1.10
/etc/autofs/auto.cifs
# directory mount options device to mount
ian -fstype=cifs,ro,soft,user=ian ://192.168.1.10/export/home/ian
deb -fstype=cifs,ro,soft,user=deb ://192.168.1.10/export/home/deb
Folders /media/cifs/ian and /media/cifs/deb will be created.
/etc/autofs/auto.sshfs
# directory mount options device to mount
ian_ssh -fstype=fuse,rw,allow_other,IdentityFile=/path/to/ssh_key :sshfs\#user@192.168.1.10\:/mnt/folder/
Folder /media/sshfs/ain_ssh will be created.
