It's written in front of it. On a whim, I'm going to open a blog, dig out the things from a long time ago and move here one by one, so that it doesn't seem so empty.

-- written in front--

I haven't paid attention to security for a long time. Today I accidentally took a look at the security cordon (http://www.hackeroo.com/) MS08-066 MS08-067 MS08-068. A lot of exploit tools have sprung up recently. It seems that Microsoft things should be used carefully.

Find a tool to scan it. I haven't used domestic scanning tools for too long, there is always something to worry about, especially the tools provided by hacker sites are far less secure than those provided by rootkit, although you need to download your own source code to compile.

What's depressing is that there are no previous rootkit sites in my favorites (it looks like it's time to reorganize my favorites). Unexpectedly think of what to look for in a busy meal, isn't it just scanning the lower port? is there anything so simple and easy to use than Nmap?

The Nmap on my machine was a few years ago, so I had to download a new one. Let's briefly explain the usage.

First, use nmap for the first time

There are so many parameters in Nmap that you can read it directly when you are not in a hurry.

Namp hostname (IP is also available)

such as

Nmap news.sina.com.cn (here is the typed command) the following italics is the display of the screen
