在NFS客户端执行该命令时报下列错误

[root@client ~]# showmount -e 192.168.0.1
clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)

解决方法

[root@server ~]# iptables -F
[root@server ~]# iptables -X

再执行该命令

[root@client ~]# showmount -e 192.168.0.1
Export list for 192.168.0.1:
/data/share *
