I'm using socks proxy over ssh tunnel

ssh -D 1080 -f -C -q -N <user>@<server>

when I set the proxy in System settings > Network > Network proxy, all applications like Chromium, Firefox, apt, ... are following the proxy.

enter image description here

now I want to write a shell script for automation, how can I set Network proxy by terminal?

all I found is "use some third-party software like Tsocks and ...". but as I said, the ubuntu it self can do this without any third-party software so don't want to use them.

all I want is set Network proxy using a command in terminal.

    Potentially a dupe of http://askubuntu.com/questions/664777/systemwide-proxy-settings-in-ubuntu - check the accepted answer's 3rd point about `/etc/environment`, but using localhost instead eg `http_proxy=http://localhost:1080` – taifwa Apr 11 '17 at 13:04

as @taifwa said, Systemwide proxy settings in ubuntu was the solution.

and here is my script:

    ssh -D ${LOCAL_PORT} -f -C -q -N ${REMOTE_USER}@${REMOTE_HOST} -p ${REMOTE_PORT}

    #set socks setting in System settings > Network > network proxy 
    gsettings set org.gnome.system.proxy mode 'manual'
    gsettings set org.gnome.system.proxy.socks port ${LOCAL_PORT}
    gsettings set org.gnome.system.proxy.socks host 'localhost'
    gsettings set org.gnome.system.proxy ignore-hosts "['localhost', '127.0.0.0/8', '${LOCAL_RANGE}', '::1']"

    sudo su <<-EOF  
    #environment settings
    echo "socks_proxy='socks://localhost:${LOCAL_PORT}/'" >> /etc/environment 
    #apt settings
    echo "Acquire::socks::proxy 'socks://localhost:$LOCAL_PORT/';" >> /etc/apt/apt.conf
    EOF

run as root is required for editing environment and apt.conf,

edit:

but it's important to know editing org.gnome.system.proxy as root has no effect on current user, so them should run as normal user. so don't run the script with sudo

    I know that this space isn't for saying thanks but you saved my whole day. I wish that I found this sooner. – Raza Mar 04 '19 at 09:24
  • Does this script only work for Gnome, not for Xfce? – sequence Oct 14 '21 at 12:32
  • I don't this test on Xface. – M.A. Heshmat Khah Oct 14 '21 at 15:52
  • Using gsettings to set socks results in generating environmental variables 'ALL_PROXY' and 'all_proxy' as 'socks://xxx:yyy', which neglects the VERSION of socks. Do you know how to make gsettings generate these environmental variables as 'socks5://xxx:yyy' instead? This is important to me because many apps can't detect the version of socks automatically, including pip. – cyfex May 09 '23 at 13:26
