Vulnerability Analysis of an attack Tracing System (affecting customers' core network segments and sensitive monitoring information) The device is deployed on the Intranet. the device is directly connected to the host device monitored on the Intranet or the trunk route. The device needs to connect to the Internet and the cloud is connected.It's been a long time to let it go. You need to synchronize the rule

In the past, I wrote a monitoring script to check the IP addresses in an IP list every 10 seconds by using the ping command. If the IP addresses in an IP list cannot be accessed, send messages via the messenger message and use beep to send alarms. Run the script.Rem main. bat @ Echo off For/F "EOL =; tokens = 1, 2 * delims =" % I in (IP. txt) Do call: checkip % I % j 0 Echo -------------------------------------------------------------- Echo ---- the f

1. Gmetad layering;2. rrdcached Cache;3. Replace the SSD or other fast storage device to avoid HDD storage;Use a device with a large write cache, such as RAID, etc.If the cluster is small and the total amount of files generated is not very large, it is stored directly using RAM and regularly backed up.4. Use large chunks of logical volumes to avoid an update to an RRD file that results in multiple IO calls.5. File system-Level optimizations: noatime, etc.6. Web-side browsing, using a reverse pro

Iftop This is a very useful tool. The following command monitors the wireless card in my NotebookIftop-i Wlan0For example, I'm playing music video now. Information displayed by Iftop:Basic Description:1. The main part of the screen represents data transfer between two machines, with arrows indicating direction. The three values on the right are each of the past 2 seconds. Average traffic for 10 seconds and 40 seconds.2 TX in the lower-left corner represents the emitted data. RX Indicates the dat

Ntop is very powerful, so I will not explain it here. There are a lot of introductions on the Internet and I will not repeat them here. The installation steps are as follows: 1. Adding apt sources Vim/etc/APT/source. listdeb http://backports.debian.org/debian-backports wheezy-backports main 2. Update apt Source: Apt-Get update 3. Install ntop package Apt-Get install ntop-y 4. Enter some information: Enter the name of the ENI to be monitored, such as eth1 Enter the ntop logon Password Ent
