关于NFS的问题

terryyj

今天在做NFS的练习,设好了/etc/exports{/var/ftp/pub   10.0.0.3(ro)},然后启动portmap和NFS服务,本机IP地址10.0.0.3,我用mount 127.0.0.1:/var/ftp/pub /mnt/nfs
然后提示mount: 127.0.0.1:/var/ftp/pub/ failed, reason given by server: Permission denied
然后在/var/log/messages给我这样的提示Oct 15 11:24:35 localhost rpc.mountd: refused mount request from localhost.localdomain for /var/ftp/pub (/): no export entry
如果我用mount 10.0.0.3:/var/ftp/pub /mnt/nfs,那么可以正常mount到,为什么用127.0.0.1就不行呢?如果要使127.0.0.1可以的话,那么需要怎么做?
