关于sudoer中来源主机限制问题？

blueswxs

先来一段手册

        jack           CSNETS = ALL

       The user jack may run any command on the machines in the
       CSNETS alias (the networks 128.138.243.0, 128.138.204.0, and
       128.138.242.0).  Of those networks, only 128.138.204.0 has an
       explicit netmask (in CIDR notation) indicating it is a class
       C network.  For the other networks in CSNETS, the local
       machine’s netmask will be used during matching.


CSNETS 定义主机别名。

根据这个例子，我写了一个：

Host_Alias      HHH = 10.10.10.158/255.255.255.255
uuu     HHH=(root)      NOPASSWD:ALL


可是当我在10.10.10.158的服务往ppp.uplooking.com建立ssh连接以后，执行如下命令。确失效：

[uuu@ppp ~]$ sudo /sbin/fdisk -l
Password:
uuu is not allowed to run sudo on ppp.  This incident will be reported.
[uuu@ppp ~]$ hostname
ppp.uplooking.com
