## 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`
### UID mapping

## Linux Client
`# pacman -S nfs-utils`
`# apt install nfs-common`
Mount through terminal
`# mount -t nfs4 (ip):(mountpoint) (local mountpoint)`
Can also be mounted with fstab
## Windows Client
Search for `Turn Windows features on or off`
Check everything under `Services for NFS` and click "OK"
Mount as mapped network drive
`mount -o anon \\(ip)\(mountpoint) (letter):`
