MNNIT Proxy Settings

Basic Instructions

Proxy configuration

apt - default package manager on most debian based distros

Proxy configuration for apt is written in the following file

/etc/apt/apt.conf

To configure apt proxy:

Open terminal and open the above mentioned file in any text-editor with sudo . Eg.
```
 sudo gedit /etc/apt/apt.conf
```

Add the following exact lines in the file(Change the proxy IP accordingy) :

  Acquire::http::proxy "http://edcguest:edcguest@172.31.102.29:3128/";
  Acquire::https::proxy "http://edcguest:edcguest@172.31.102.29:3128/";
  Acquire::ftp::proxy "http://edcguest:edcguest@172.31.102.29:3128/";

Save the file (Ctrl+S for gedit) and close the editor.
Run the following command to test the configuration.
```
  sudo apt update
```
If the command executes without error the configurattion is successful.

pacman - default package manager on Arch based distros

pacman uses the terminal environment varialbles for proxy configurations.

To temporarily configure proxy for pacman, open the terminal and type the following commands:

  export http_proxy="http://edcguest:edcguest@172.31.102.29:3128/"
  export https_proxy="http://edcguest:edcguest@172.31.102.29:3128/"
  export ftp_proxy="http://edcguest:edcguest@172.31.102.29:3128/"

The above lines set proxy variables for the terminal, so all programs that use the terminal environment variables for proxy configuration like wget, curl etc. will also use the above proxy settings.

To make this setting permanent, add the above two lines in the .bashrc file:

First create a backup of the .bashrc file.
```
  cp ~/.bashrc ~/.bashrc.bkp
```

Add the following lines to the last of the .bashrc file. Open .bashrc in a text editor eg: gedit ~/.bashrc

  export http_proxy="http://edcguest:edcguest@172.31.102.29:3128/"
  export https_proxy="http://edcguest:edcguest@172.31.102.29:3128/"
  export ftp_proxy="http://edcguest:edcguest@172.31.102.29:3128/"

yum - default package manager for CentOS, RHEL etc.

Proxy configuration for yum can be done through /etc/yum.conf

Open the file with sudo permissions eg: sudo vi /etc/yum.conf or sudo gedit /etc/yum.conf

Under the [main] section define proxy settings:

  [main]
  proxy=http://172.31.102.29:3128
  proxy_username=edcguest
  proxy_password=edcguest

Save the file and close the editor.

Alternate way to set the proxy:

Add the following lines to the last of the /root/.bashrc file. Open /root/.bashrc in a text editor eg: sudo gedit ~/.bashrc

  export http_proxy="http://edcguest:edcguest@172.31.102.29:3128/"
  export https_proxy="http://edcguest:edcguest@172.31.102.29:3128/"
  export ftp_proxy="http://edcguest:edcguest@172.31.102.29:3128/"
