π¦ What is a proxy server
twitter.com/UndercOdeTC
in the TCP / IP network, the traditional communication process is this:
1) the client requests data to the server, the server response Data should be transmitted to the client upon request.
2) After the introduction of the proxy server, the process becomes like this: the client initiates a request to the server, and the request is sent to the proxy server; the proxy server analyzes the request, and first checks whether there is request data in its cache, and directly Transfer to the client, if not, make a request to the server on behalf of the client.
3) After the server responds, the proxy server transmits the response data to the client, while keeping a copy of the data in its own cache. In this way, when another client requests the same data, the proxy server can directly transmit the data to the client without having to initiate a request to the server.

π¦ Features Of Proxy Server :
instagram.com/UndercOdeTestingCompany
π¦ ππΌππ πππΈβπ :
> Generally speaking, the proxy server has the following features:
1) increase access speed by caching
> With the rapid development of Internet, network bandwidth is becoming increasingly rare. Therefore, in order to improve the access speed, many ISPs provide proxy servers, which use the cache function of the proxy server to speed up the network access speed. Generally speaking, most proxy servers support HTTP caching, but some proxy servers also support FTP caching. When choosing a proxy server, for most organizations, only HTTP caching is sufficient.
Generally, caches are classified as active caches and passive caches. The so-called passive cache means that the proxy server caches the data returned by the server only when the client requests data. If the data expires and the client requests the same data, the proxy server must re-initiate a new data request. When the response data is transmitted to the client, a new cache is performed. The so-called active cache means that the proxy server continuously checks the data in the cache. Once the data expires, the proxy server actively initiates a new data request to update the data. In this way, when a client requests the data, the response time is greatly reduced. It should also be noted that most proxy servers do not cache the authentication information in the data.
2) Provide a method for accessing the Internet with a private IP.
IP addresses are valuable resources that are not renewable. If you have only limited IP addresses but need to provide Internet access for the entire organization, then you can achieve this by using a proxy server.
3) To improve network security
This is very clear, if all internal users to access the Internet through a proxy server, then the proxy server will become the only channel into the Internet; conversely, the proxy server is the only Internet access to internal network Channel, if you do not do reverse proxy, for the host on the Internet, only the proxy server of your entire intranet is visible, which greatly enhances the security of the network.

Transparent proxy means that clients do not need to know the existence of the proxy server.
Based on the above we do the following:
1) Configure the transparent proxy server software to run on port 8080 of the proxy server.
2) Configure the proxy server to redirect all connections to port 80 to port 8080.
3) Configure the client browser to connect directly to the Internet.
4) Configure DNS on the client.
5) Configure the client's default gateway to 192.168.1.1.
> When we open a web request in the client browser, such as " http://www.yourdomain.com ", at this time The following events will occur one after another:
1) The client requests "www.yourdomain.com" from DNS and obtains the corresponding IP address 202.99.11.120. Then, the client uses a certain port (such as 1066) to initiate a web connection request to port 80 of the IP address, requesting a web page.
2) When the request packet passes through the transparent proxy server, it is redirected to the bound port 8080 of the proxy server. Therefore, the transparent proxy server uses a certain port (such as 1088) to initiate a web connection request to port 80 of 202.99.11.120 to request a web page.
3) After receiving the response web page, the proxy server transmits the data to the client.
4) The client browser displays the page.
From the perspective of www.yourdomain.com, the connection is established between port 1088 at port 1.2.3.4 and port 80 at 202.99.11.120. From the client's perspective, the connection is established between port 1066 at 192.168.1.100 and port 80 at 202.99.11.120.

In the following chapters, we will learn about Squid's exciting features and related installation and configuration.
π¦ Now install Proxy Server Squid
A) acquisition software
you can get the software in the following ways:
1) From the official site of Squid http://www.squid-cache.org download the software;
2) From your linux release Obtain the software;
Generally, there are two types of Squid packages: one is the source code, which needs to be recompiled after downloading; the executable file can be used after decompression after downloading; the other is the rpm package used by RedHat. Below we talk about the installation methods of these two software packages.
B) Installing the software
we present the latest stable version of squid-2.3.STABLEX example.
3.2.1rpm package installation
1) Go to / mnt / cdrom / RedHat / RPMS
2) Run rpm -ivh squid-2.2.STABLE4-8.i386.rpm.
Of course, we can also install the software during the process of
π¦ installing the system.
C) Installation of Source Code Package
1) Download squid-2.3.STABLE2-src.tar.gz from http://www.squid-cache.org .
2) Copy the file to the / usr / local directory.
3) Unzip the file tar xvzf squid-2.3.STABLE2-src.tar.gz.
4) After unzipping, generate a new directory squid-2.3.STABLE2 in / usr / local. For convenience, use the mv command to rename the directory squid-2.3.STABLE2 squid;
5)Enter squid cd squid
6) ./configure can be performed ./confgure --prefix = / directory / you / want installation directory specified
default installation directory / usr / local / squid.
7) Execute make all
8) Execute make install
9) After installation, Squid's executable file is in the bin subdirectory of the installation directory, and the configuration file is in the etc subdirectory.

2) The quick_install.sh script automatically downloads the latest version of vlany from this repository, untars the archive, then executes the regular installation script from a new random directory in /tmp/. By default, the quick_install.sh script removes the new directory once execution has completely finished.
3) it's very simple to install vlany onto a sytem as it comes with an automated install script.
To install vlany you want to first download it from our GitHub ( Always up to date and trusted )
root@vlany:~# wget https://github.com/mempodippy/vlany/archive/master.tar.gz && tar xvpfz master.tar.gz
4) Once it's downloaded you just have to run install.sh inside vlany-master.
root@vlany:~# cd vlany-master && ./install.sh
By default this will prompt you with a tui installation but if cli is prefered you can use the --cli argument to invoke a similar cli installation.

π¦updated 2020 bash package manager - usefull script :
t.me/UNdercOdeTesting
π¦ πβπππΈπππππΈπππβ & βπβ:
1) placing bpkg and related scripts on /usr/local/bin.
Paste the following on your shell and you're good to go:
$ curl -Lo- "https://raw.githubusercontent.com/bpkg/bpkg/master/setup.sh" | bash
2) clib is a package manager for C projects. If you already have it, installing bpkg is a simple matter of:
$ clib install bpkg/bpkg
3) Source Code
To directly install bpkg from its source code you have to clone its repository and run the setup.sh script:
> git clone https://github.com/bpkg/bpkg.git
> cd bpkg
> ./setup.sh # Will install bpkg in $HOME/.local/bin
> sudo ./setup.sh # Will install bpkg in /usr/local/bin.
> PREFIX=/my/custom/directory ./setup.sh # Will install bpkg in a custom directory.
2) Packages can either be global (on /usr/local/bin if installed as root or
> HOME/.local/bin otherwize) or local (under ./deps).
For example, here's a global install for the current user of the term package:
3) bpkg install term -g
4) term
And the same package as a local install:
5) bpkg install term
6) ./deps/term/term.sh
7) After a local install the term.sh script is copied as term to the deps/bin directory, you can add this directory to the PATH with
> export PATH=$PATH:/path_to_bkpg/deps/bin
8) As a bonus, you can specify a specific version:
$ bpkg install jwerle/suggest.sh@0.0.1 -g
9) You can also install packages without a package.json. As long as there is a Makefile in the repository it will try to invoke make install as long as the -g or --global flags are set when invoking bpkg install.
For example you could install git-standup with an omitted package.json because of the Makefile and the install target found in it.
> $ bpkg install stephenmathieson/git-standup -g
info: Using latest (master)
warn: Package doesn't exist
warn: Missing build script
warn: Trying `make install'...
info: install: `make install'

π¦ πβπππΈπππππΈπππβ & βπβ:
1) git clone https://github.com/neurobin/shc
2) cd shc
3) ./configure
4) make
5) sudo make install
6) If make fails due to automake version, run ./autogen.sh before running the above commands.
π¦ Ubuntu-specific
1) sudo add-apt-repository ppa:neurobin/ppa
2) sudo apt-get update
3) sudo apt-get install shc
4) If the above installation method seems like too much work, then just download a compiled binary package from release page and copy the shc binary to /usr/bin and shc.1 file to /usr/share/man/man1.
π¦ Usage
1) shc [options]
2) shc -f script.sh -o binary
3) shc -U -f script.sh -o binary # Untraceable binary (prevent strace, ptrace etc..)
4) shc -H -f script.sh -o binary # Untraceable binary, does not require root (only bourne shell (sh) scripts with no parameter)
π¦ The hardening flag -H
> This flag is currently in an experimental state and may not work in all systems. This flag only works for default shell. For example, if you compile a bash script with -H flag then the resultant executable will only work in systems where the default shell is bash. You may change the default shell which generally is /bin/sh which further is just a link to another shell like bash or dash etc.
> Also -H does not work with positional parameters (yet)
π¦ Testing :
./configure
make
make check
./configure
make
make check
π¦ If you want to edit the manual, please edit the man.md file (available in the master branch) instead and then generate the manual file from it with the command (requires pandoc to be installed):
> pandoc -s man.md -t man -o shc.1
#also run this command to generate the html manual
> pandoc -s man.md -t html -o man.html
