The idea of penetrating attacks is generally to scan for vulnerabilities and then exploit different vulnerabilities to attack penetration.Vulnerability Scanning Tool has nessus, the tool can be at the same time on the local or remote control, the vulnerability analysis of the system scan.

The system environment is centos5.3 + jdk6 + tomcat6.0.20 + struts2.1.6 + spring2.5.6. Struts2 uses two plug-ins: struts2-convention-plugin-2.1.6.jar and struts2-spring-plugin-2.1.6.jar.

, which priority is the priority? What happens when a process has 2 priority levels?In fact, the Linux kernel has long been a solution.For the first question, which priority is more priority?The answer is that the real-time priority is higher than the nice value, and in the kernel, the real-time priority range is 0~max_rt_prio-1 Max_rt_prio definition see include/linux/sched.h1611 #define Max_user_rt_prio 1001612 #define Max_rt_prio Max_user_rt_prioThe nice value in the kernel
the nice value.So what if a couple of processes have the same two priorities at the same time?Priority, while the normal process corresponds to the nice value. In this case, there is no theory that a process has two different priority levels at the same time. Is that the truth? Repeat the above sentence: the process in Linux is divided into real-time processes and ordinary processes. Real-time processes correspond to real-time priorities. The normal process corresponds to the nice value. In thi

To reduce the thread execution period, we designed eka2 to be multi-threaded, allowing low-priority kernel operations to be preemptible by high-priority kernel operations.
Eka2 has five threads:
1. null thread -- idles CPU, and de-fragments Ram. This thread is also called idle thread
2. Manager thread-kill killed threads and processes (killed
