## Linux Server
|
|
|
|
`# apt install nfs-server`
|
|
|
|
Shares can be configured in `/etc/exports`
|
|
`<mountpoint> <allowed_ip>(<option1>,<option2>) <allowed_ip2>(<option1>,...)`
|
|
|
|
### Options
|
|
|
|
```
|
|
ro: specifies that the directory may only be mounted as read only
|
|
rw: grants both read and write permissions on the directory
|
|
no_root_squash: is an extremely dangerous option that allows remote “root” users the same privilege as the “root” user of the host machine
|
|
subtree_check: specifies that, in the case of a directory is exported instead of an entire filesystem, the host should verify the location of files and directories on the host filesystem
|
|
no_subtree_check: specifies that the host should not check the location of the files being accessed withing the host filesystem
|
|
sync: this just ensures that the host keeps any changes uploaded to the shared directory in sync
|
|
async: ignores synchronization checks in favor of increased speed
|
|
```
|
|
|
|
_Example single host:_
|
|
`/mnt/nfs 192.168.1.123(rw,sync,no_subtree_check)`
|
|
|
|
_Example whole subnet:_
|
|
`/mnt/nfs 192.168.1.0/24(rw,sync,no_subtree_check)`
|
|
|
|
Apply new config by restarting the service.
|
|
`# systemctl restart nfs-server`
|
|
|
|
Show configured shares
|
|
`$ cat /var/lib/nfs/etab`
|
|
|
|

Can also be mounted with fstab
