求助：NFS挂载的问题（暂时解决）

高热

nfs server端为debian 5.0，安装nfs-user-server.
/etc/exports文件：

/home/armel 192.168.1.0/255.255.255.0(rw,no_root_squash,no_all_squash)

客户端为嵌入式系统，linux kernel + busybox。在客户端挂载时输入：

mount -t nfs 192.168.1.5:/home/armel /mnt

返回下面的错误:

svc: failed to register lockdv1 RPC service (errno 111).
lockd_up: makesock failed, error=-111
mount: mounting 192.168.1.5:/home/armel on /mnt failed: Connection refused

此时在服务器端却看到:

Aug 16 18:18:52 debian mountd[14767]: NFS mount of /home/armel attempted from 192.168.1.2
Aug 16 18:18:52 debian mountd[14767]: /home/armel has been mounted by 192.168.1.2

客户端内核是自己编译的，怀疑这个问题是由于有什么东西没编进内核导致的。
内核相关选项：

CONFIG_NETWORK_FILESYSTEMS=y
CONFIG_NFS_FS=y
# CONFIG_NFS_V3 is not set
# CONFIG_NFS_V4 is not set
CONFIG_ROOT_NFS=y
# CONFIG_NFSD is not set
CONFIG_LOCKD=y
CONFIG_NFS_COMMON=y
CONFIG_SUNRPC=y
# CONFIG_RPCSEC_GSS_KRB5 is not set
# CONFIG_RPCSEC_GSS_SPKM3 is not set

能否给些提示？

暂时用下面的方法解决，还不明白为什么

mount -t nfs -o nolock 192.168.1.5:/home/armel /mnt
