🦑Random Key terms:

>Feeder - Source of IP addresses for scanning. Angry IP Scanner provides various scanning sources: IP Range, IP List File or Random. You can select a source from the drop-down list next to the "Start" button

>Data collector - collects specific information about the host, for example, ping time, host name, open ports. Collectors are usually columns as a result of a scan. They can be selected in the menu "Tools-> Data Collectors".

>Active host - the host responding to ping. The results sheet is marked in blue.

>Inactive host - a host that does not respond to ping (red). However, it may have open ports (if the firewall blocks ping). In order to fully scan such hosts, check the "Scan inactive" checkbox in Tools-> Preferences.

>Pinging (host check):

>ICMP echo is the standard method used by the 'ping' program. On most platforms, requires administrator privileges. Some firewalls prohibit response packets to an ICMP request, making active hosts look inactive.

>UDP - sends UDP packets (datagrams) to one of the host ports and monitors the response (whether or not). Not standard, but does not require privileges.

>TCP - trying to connect to the 80 (http) port. UDP may work better for some networks, usually not.

>Scanning UDP and TCP most often does not detect routers or other network equipment properly

> Open port - TCP port that responded to the connection attempt. Greens on the list.

🦑 Outlaw botnet infects about 20,000 Linux servers, Tencent security reminds enterprises to remove in time
#news

>The parent file transmitted by this attack is dota3.tar.gz, which may be the third version of the Outlaw botnet. The parent file releases a shell script to start the corresponding binary program. kswapd0 is responsible for mining Monero, tsm32, tsm64 is responsible for continuing the SSH blast attack to spread the virus.

>The Outlaw botnet was previously distributed by exploiting the Shellshock vulnerability, so it was named "Shellbot". Shellbot uses common command injection vulnerabilities on Internet of Things (IoT) devices and Linux servers to infect. The Shellshock vulnerability (CVE-2014-7169) is a serious vulnerability discovered in the Bash command shell in 2014. Most Linux distributions usually use this feature, and attackers can remotely execute code on these affected Linux servers.

>Outlaw botnets use SSH to blast intrusive attacks, which can be detected

> Cloud Firewall can detect the mining behavior of Outlaw botnet, Shellshock exploit and brute force cracking of SSH login password and other attack activities.

At present, the impact of the Outlaw botnet is still spreading, causing serious harm to enterprise servers. Tencent security products have taken emergency response measures

🦑How do multiple WAN routers set the internal IP to correspond to the fixed WAN port? LAN IP address settings

How do multiple WAN routers set the intranet IP to correspond to a fixed WAN port? There are a lot of broadband, in order to ensure the network speed, I want to let some computers take the top route, so that the speed of the distribution network is very fast, we need to set the LAN IP address, let's take a look at the detailed tutorial, friends You can refer to

> When using multiple broadband, in order to ensure that some special computers have sufficient speed, we can let these computers take the designated route and separate from other computers. Next, let's operate how to set the specified LAN IP from the specified WAN port of the multi-WAN router.

1️⃣ First, set up an address group, and put the IPs to be specially processed into a group.

2️⃣ Open the " Routing Settings " in " Transmission Control "

3️⃣ into the " policy PBR list of rules ", click " Add"

4️⃣in the source address, select the IP address group to be set on the WAN2 port.

5️⃣ Select " WAN2" for the effective interface and let it go to the WAN2 port.

6️⃣Others can keep the default, click " OK" to save the settings

7️⃣Now you can go to test whether it has gone to the designated WAN port.

great! that's all

🦑 The difference between file descriptors and file pointers:
#fastTips

> File descriptor: Open the file in the linux system to get the file descriptor, which is a small positive integer. Each process stores a file descriptor table in the PCB (Process Control Block). The file descriptor is the index of this table, and each entry has a pointer to the opened file.

> File pointer: The file pointer is used as the handle of I/O in C language. The file pointer points to a data structure called the FILE structure in the process user area. The FILE structure includes a buffer and a file descriptor. The file descriptor is an index of the file descriptor table, so in a sense, the file pointer is the handle of the handle (on Windows systems, the file descriptor is called the file handle).

🦑 What is Socket :
#prohack

1️⃣ Socket socket:

Socket originated from Unix, and one of the basic philosophy of Unix/Linux is "everything is a file", which can be operated with the "open open -
> read/write -> close" mode. Socket is an implementation of this mode, socket is a special file, and some socket functions are operations on it (read/write IO, open, close).

> To put it plainly, Socket is the application layer to communicate with the TCP/IP protocol family The middleware abstraction layer is a set of interfaces. In the design mode, Socket is actually a facade mode. It hides the complex TCP/IP protocol family behind the Socket interface. For users, a simple set of interfaces is all. Let Socket organize the data to meet the specified protocol.

🕳Note: In fact, the socket has no concept of layers, it is just a facade design pattern application, making programming easier. It is a software abstraction layer. In network programming, we use a lot of sockets.

2️⃣The socket descriptor is
actually an integer. The handles we are most familiar with are 0, 1, and 2, 0 is standard input, 1 is standard output, and 2 is standard error output. 0, 1, 2 are represented by integers, the corresponding FILE * structure is stdin, stdout, stderr

> The socket API was originally developed as part of the UNIX operating system, so the socket API is integrated with other I/O devices in the system. In particular, when an application wants to create a socket for Internet communication, the operating system returns a small integer as a descriptor to identify the socket. Then, the application program uses the descriptor as a transfer parameter to complete a certain operation by calling a function (such as transmitting data through the network or receiving input data).

3️⃣In many operating systems, socket descriptors and other I/O descriptors are integrated, so applications can perform socket I/O or I/O read/write operations on files.

4️⃣When an application wants to create a socket, the operating system returns a small integer as a descriptor. The application uses this descriptor to refer to the socket. An application that requires an I/O request requests the operating system to open a file. The operating system creates a file descriptor for the application to access the file. From the perspective of the application, the file descriptor is an integer that the application can use to read and write files.

🦑Termux optimization :

> Terminal color
Mainly used zshto replace bashas the default shell. Use one-click installation script to install, one-step installation, by the way, external storage is started, and you can directly access the directory under the SD card.

1️⃣ Execute the following command to ensure that curl is installed

> sh -c "$(curl -fsSL https://github.com/Cabbagec/termux-ohmyzsh/raw/master/install.sh)"

2️⃣Android 6.0 and above will pop up a box to confirm whether it is authorized.

3️⃣After authorization, Termuxyou can easily access the SD card file. After the script allows, you have the following two options:

> Enter a number, leave blank to not to change: 14 Enter a number, leave blank to not to change: 6

> Select separately

> you want to continue to change the selection color, continue to run the script to filter again:

$ ~/termux-ohmyzsh/install.sh
exitRestart sessionssession effective configuration

4️⃣Access to external storage optimization :

> After executing the above zshone-click configuration script and granting file access permissions, a directory will be generated at home directory storageand several directories will be generated , and the soft links will all point to the corresponding directory of the external memory card
