# Server
daemons:
- nfsd : handles reqs from nfs clients
- mountd : handles reqs from nfsd
- rpcbind : allows nfs clients to discover which port the NFS server is using
# Exports
`/etc/exports` contains table of FS' that are exported over NFS. Newline-seperated list of exports that are in turn whitespace seperated with clients allowed to mount there. A client can be followed by parenthesised comma-seperated list of export opts.
Default opts can be specified at the end behind a dash.
**Client specs**
- Single host (name or ip)
- Netgroups
- Wildcards (`?` or `*` and `[]` char classes)
- IP networks (`ipaddr/netmask` )
**Some useful options**
- rw
- ro
**Example**
```
/nfs 192.168.50.0/24(rw,sync,insecure,no_subtree_check)
```
