NFS Service Configuration Fixed port

#Linux NFS Service Fixed port and firewall configuration #

1. Install the NFS service normally on Linux

2. Modify the/etc/service to add the following (the port number must be below 1024 and is not occupied)
# Local Services
Mountd 1011/tcp #rpc. Mountd
Mountd 1011/udp #rpc. Mountd
Rquotad 1012/tcp #rpc. Rquotad
Rquotad 1012/udp #rpc. Rquotad

3. Restart NFS Service
Service NFS Restart
Chkconfig NFS On

4. Now that the RPC-related port is fixed, you can add a firewall rule
#portmap
/sbin/iptables-a input-s 192.168.1.0/24-p TCP--dport 111-j ACCEPT
/sbin/iptables-a input-s 192.168.1.0/24-p UDP--dport 111-j ACCEPT
#nfsd
/sbin/iptables-a input-s 192.168.1.0/24-p TCP--dport 2049-j ACCEPT
/sbin/iptables-a input-s 192.168.1.0/24-p UDP--dport 2049-j ACCEPT
