iSCSI安全之IP访问控制
在上一节中的PC架构的基础上修改。做IP控制的话，iscsi客户端不需要做什么。只需要修改iscsi target上的配置文件就行了。
1、修改/etc/iet/ietd.conf
[root@Target iet]# vi ietd.conf
Target iqn.2013-09.com.xfzhou.Target:sdb
Lun 0 Path=/dev/sdb,Type=fileio,ScsiId=xyz,ScsiSN=xyz
Target iqn.2013-09.com.xfzhou.Target:sdc
Lun 0 Path=/dev/sdc,Type=fileio,ScsiId=xyz,ScsiSN=xyz
注意这里的Target和Lun是成对出现的！
2、修改/etc/iet/initiators.allow
[root@Target iet]# vi initiators.allow
#iqn.2001-04.com.example:storage.disk1.sys1.xyz 192.168.0.0/16, .*:mscs1-[1-4]\.example\.com
#iqn.2001-04.com.example:storage.disk1.sys2.xyz [3ffe:302:11:1:211:43ff:fe31:5ae2], [3ffe:505:2:1::]/64, 192.168.22.0/24
#iqn.2001-04.com.example:storage.disk1.sys3.xyz ALL
#iqn.2001-04.com.example:storage.disk1.sys4.xyz 192.168.22.3, iqn\.1998-01\.com\.vmware:.*\.example\.com
iqn.2013-09.com.xfzhou.Target:sdb 192.168.10.10
iqn.2013-09.com.xfzhou.Target:sdc 192.168.10.201
从上面的注释可以看出：
a、在控制的时候可以写ip地址，还可以写一个网络地址；
b、还可以是一个域名，但是域名中的点要使用\来转义；
c、如果有多个不同网段的IP需要访问同一块共享的磁盘的时候，可以用逗号“,”来分隔他们。
3、在Linux客户端测试：
如果使用ip访问控制的话，那么客户端就不需要什么配置，直接重启一下iscsi服务就可以看出来了：
[root@file /]# service iscsi restart

[root@file /]#
可以发现，那个共享的sdc没有登陆成功，而新共享的那个sdb却可以登陆，说明IP访问控制生效了！
再来看下本地的磁盘：

[root@file /]#
Windows上的话，直接去刷新一下就就行了，没有什么别的操作。
