谁动了我的NFS服务器?

如何查找有多少Client连到NFS服务器上?

登录到nfs服务器上, 执行下列命令

netstat -an | grep nfs_server_ip:port 

例如, NFS服务器IP是192.168.1.200, 端口是2049

linuxgeek@host01:~# grep 2049 /etc/services 
nfs		2049/tcp			# Network File System
nfs		2049/udp			# Network File System
linuxgeek@host01:~# netstat -an | grep 192.168.1.200:2049
tcp        00192.168.1.200:2049192.168.1.201:757         ESTABLISHED
tcp        00192.168.1.200:2049192.168.1.203:892         ESTABLISHED

或者使用showmount命令, showmount -e ip/hostname, 也可以使用showmount -a显示挂载情况.
更多命令参数man showmount

linuxgeek@host01:~# showmount -e 192.168.1.200Export list for192.168.1.200:/share1/video 192.168.1.0/24/share1/docs 192.168.1.0/24/share2/user_home 192.168.1.0/24
