      NFS &autofs             

# sample /etc/exports file (setup-2.5.37-1.3)

       /               master(rw) trusty(rw,no_root_squash)

       /projects       proj*.local.domain(rw)

       /usr               *.local.domain(ro) @trusted(rw)

       /home/joe     pc001(rw,all_squash,anonuid=150,anongid=100)

       /pub              (ro,insecure,all_squash)

       The first line exports the entire filesystem to  machines  master  and trusty.In addition to write access, all uid squashing is turned off for host trusty. The second and third entry show examples for wildcard  hostnames  and  netgroups  (this  is the entry trusted). The fourth line shows the entry for the PC/NFS client  discussed  above. Line 5 exports the public FTP directory to every host in the world, executing all requests under the nobody account. The  insecure  option in this entry  also  allows  clients with NFS implementations that do use a reserved port for NFS.
