My institute provides an Internet connection with a proxy server. In other distros proxy can be set by two things,

  1. setting proxy in network manager.
    it only works in browsers or some application like vs code that ask for username and password.

  2. adding export http_proxy="http://username:password@server:port. in ~/.bashrc file.
    It works in terminal.

But in souls 4.0 only first one is working on my laptop. The second one is not working. I can't access the internet in a terminal.

    Justin Hey thanks for the reply.
    All application in terminal cant access the internet. i.e. eopkg upgrade, and yarn can't establish a connection.
    EDIT :- Here is an output of env | grep -i proxy

    HTTP_PROXY=http://2016247:PEkcKOl2@172.27.16.154:3128

        Janglee123 eopkg has a proxy configuration setting. Copy /usr/share/defaults/eopkg/eopkg.conf to /etc/eopkg/eopkg.conf and edit the proxy info under the [general] section.

            Janglee123 They may have their own proxy settings if they aren't abiding by the system set proxy config.

              That depends on the applications you are using. For some it is enough to set the following environment variable :
              set HTTP_PROXY=http://proxy_userid:proxy_password@proxy_ip:proxy_port
              And if necessary :
              set FTP_PROXY=%HTTP_PROXY%
              set HTTPS_PROXY=%HTTP_PROXY%
              For others, especially browsers, the following may do the job :
              reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1
              reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /t REG_SZ /d name:port
              reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyUser /t REG_SZ /d username
              reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyPass /t REG_SZ /d password
              netsh winhttp import proxy source=ie
