linux – 如何获取连接到本地网络中NFS服务器的客户端列表？

NFS服务器配置文件如下所示.

[root@server ~]# cat /etc/exports
/home/guests    *(rw,sync)
/india          *(rw,sync)

以下是共享文件夹列表

[root@server ~]# showmount -e
Export list for server.sanith.com:
/india       *
/home/guests *

出于测试目的,我现在已将一个客户端连接到服务器.以下输出来自“client2”机器.

[root@client2 ~]# showmount -e 192.168.1.10
Export list for 192.168.1.10:
/india       *
/home/guests *
[root@client2 ~]# mount -t nfs 192.168.1.10:/india /test
[root@client2 ~]# mount
/dev/sda2 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
/dev/sda3 on /home type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
gvfs-fuse-daemon on /root/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
192.168.1.10:/india on /test type nfs (rw,vers=4,addr=192.168.1.10,clientaddr=192.168.1.12)

我尝试使用showmount -a和showmount -d但不确定缺少的是哪些不是客户机连接的列表.

[root@server ~]# showmount -a
All mount points on server.sanith.com:
[root@server ~]# man showmount
[root@server ~]# showmount -d
Directories on server.sanith.com:
[root@server ~]# netstat -an | grep 192.168.1.10:2048
[root@server ~]# netstat -an | grep 192.168.1.10:2049
[root@server ~]# cat /var/lib/nfs/rmtab
[root@server ~]#

注意：在此测试期间,服务器上会暂时禁用防火墙.
请指教.
