今天主要测试了NM-CIDS模块（当初为什么没有买好一点的呢。。。）
主要就是一探针，里面sig设置还是满复杂的，顺便update了一下；
首先，了解了一下升级包的含义：
比如：
IPS-K9-maj-5.0-1-S149.rpm.pkg
maj代表主要升级
IPS-K9-min-5.1-1g.pkg
min代表次要升级
IPS-K9-sp-5.1-3.pkg
sp代表服务包（更加次要）
IPS-K9-r-1.1-a-5.1-1.pkg
r代表恢复升级（这里的恢复指IDS的系统恢复）
注意，大部分升级都是每年才一次的，自由IPS-SIG的才是每周，不过这次没有弄到
由于手头的IDS已经是5.0，因此做了min升级之后，接下来的sp升级log出来看看：
sensor(config)#:upgrade [url]ftp://10.1.1.100/IPS-K9-sp-5.1-3.pkg[/url]
User: aa

Warning: Executing this command will apply a service pack to the application partition. The system may be rebooted to complete the upgrade.
Continue with upgrade? []: yes
Broadcast Message from root@sensor

Applying update IPS-K9-sp-5.1-3.pkg. IPS applications will be stopped and syste
m will be rebooted after upgrade completes .
Broadcast Message from root@sensor
(somewhere) at 15:07 ...
Shutting down IPS applications. Applications will be restarted when update is
complete..
接下来就重启了：
Broadcast Message from root@sensor
(somewhere) at 15:09 ...
Update complete
Sending SIGKILL to all processes.
Please stand by while rebooting the system.
flushing ide devices: hda
Restarting system.
Initializing memory. Please wait. 512 MB SDRAM detected
……………………………………此处省略N内容
实际上就是linux的引导过程，redhat的。
这也是为什么IPS可以装在PC上的原因。
升级完成后我们看看：
