NFS

Конфигурационни файлове

• /etc/exports - задаване на споделените папки
• /etc/default/nfs-common - настройка портове, ...
• /etc/default/nfs-kernel-server - настройки Kerberos, изключване nfs4, ...

Инсталация

В зависимост дали машината е NFS клиент или NFS сървър се инсталира съответния пакет:

NFSv4 client

# apt-get install nfs-common 

NFSv4 server

# apt-get install nfs-kernel-server 

For the error message: mount.nfs4: No such device

You will have to load the nfs module with the command

1. modprobe nfs

NFSv4 without Kerberos

NFSv4 Server Let's say we want to export our users' home directories in /home/users. First we create the export filesystem:

1. mkdir /export
2. mkdir /export/users

and mount the real users directory with:

1. mount --bind /home/users /export/users

To save us from retyping this after every reboot we add the following

line to /etc/fstab /home/users /export/users none bind 0 0

In /etc/default/nfs-kernel-server we set: NEED_SVCGSSD=no # no is default because we are not activating NFSv4 security this time.

In /etc/default/nfs-common we set: NEED_IDMAPD=yes NEED_GSSD=no # no is default To export our directories to a local network 192.168.1.0/24

we add the following two lines to /etc/exports /export 192.168.1.0/24(rw,fsid=0,no_subtree_check,sync) /export/users 192.168.1.0/24(rw,nohide,insecure,no_subtree_check,sync)

Debug

If your problem involves the inability mount or export shares please also include: a copy of your /etc/exports file

• the output of rpcinfo -p localhost run on the server
• the output of rpcinfo -p servername run on the client
