Linux Mint Network Proxy Preferences doesn’t affect command line apps

linux-mintnetworkingPROXYUbuntu

I am running Linux Mint 11 (Katya) with GNOME 2 and am behind a corporate proxy. I've gone into the Network Proxy Preferences and put in my auto-configuration URL, and this seems to work for things like Pidgin and Chrome (though not Thunderbird…), but it does not affect programs that I run from the terminal, e.g. ssh, telnet, git, et al. I have hit "Apply System-Wide…" button in Network Proxy Preferences, which prompts me for my password twice, but it doesn't seem to help.

Any thoughts?

Simply edit your /etc/profile file with ie, nano:

sudo nano /etc/profile

and at the end of the file add

http_proxy="http://user:password@foo_server:port"
https_proxy="http://user:password@foo_server:port"
ftp_proxy="http://user:password@foo_server:port"
export http_proxy ftp_proxy https_proxy

where foo_server is your proxy server, and port is the port you need to connect to your proxy server.

To check if the new settings are in use simple use type source /etc/profile and you can then check that the server is in use with (install curl if you don't have it yet)

curl icanhazip.com

that should return your proxy server's address.

Software like git, ssh, telnet, will tend to ignore those settings and use their own, I know that there are several utilities for ssh that allow you to do that. There wont be a unique, works for all way of doing it.

Maybe separate questions, regarding each service you want to use is a better option than asking for a global way of making it work, the short answer here would be: there is no global way.

Ubuntu – Linux command line to turn off proxy

As the other answer says there are some programs that don't look at the system at all you may have to set them up individually. For instance wget has a number of proxy options, that can be used to ignore or adapt the environmental proxy config during execution. Here are a number of areas in which the systems proxys can be set up.

How my system looks, note that you will have to change the specifed system configuration for you networking Environment.

Some Linux systems use /etc/environment

$ cat /etc/environment 
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
http_proxy="http://192.168.1.250:8080/"
ftp_proxy="ftp://192.168.1.250:8080/"
https_proxy="https://192.168.1.250:8080/"

There is no uniform single set up other use env

$ env | grep -i proxy
NO_PROXY=localhost,127.0.0.0/8,127.0.1.1
http_proxy=http://192.168.1.250:8080/
FTP_PROXY=ftp://192.168.1.250:8080/
ftp_proxy=ftp://192.168.1.250:8080/
all_proxy=socks://192.168.1.250:8080/
ALL_PROXY=socks://192.168.1.250:8080/
HTTPS_PROXY=https://192.168.1.250:8080/
https_proxy=https://192.168.1.250:8080/
no_proxy=localhost,127.0.0.0/8,127.0.1.1
HTTP_PROXY=http://192.168.1.250:8080/

I would check out the ~/.bashrc to have setting applied automatically on system start up.

$ man env
$ man set
$ # The file section near the end of the bash manual.
$ man bash 

FILES
       /bin/bash
              The bash executable
       /etc/profile
              The systemwide initialization file, executed for login shells
       /etc/bash.bashrc
              The systemwide per-interactive-shell startup file
       /etc/bash.bash.logout
              The systemwide login shell cleanup file, executed when  a  login
              shell exits
       ~/.bash_profile
              The personal initialization file, executed for login shells
       ~/.bashrc
              The individual per-interactive-shell startup file
       ~/.bash_logout
              The  individual  login shell cleanup file, executed when a login
              shell exits
       ~/.inputrc
              Individual readline initialization file

Linux – Installing Ubuntu or Mint from behind a proxy

The logging using the suggested solution showed lots of errors in dealing with filesystem, etc.. Installation hangs for very long periods of time and never finishes. I think the problems occur because ubiquity is trying to run as user. I am installing Linux Mint 16 Cinnamon edition (64 bit). The system previously had a Cent OpenStack system with LVM installed on it.

I found another approach that worked flawlessly. It requires you to elevate into root before you run ubiquity. But you must also provide the required proxy environment variables....

Boot the Mint CD to the trial desktop...

Set manual proxy in the system settings, set whatever proxy settings you need for your networking environment.
Start terminal.
Enter the command:

sudo -E bash
Now you are in a root session with the environment inherited from the user session (-E option did this for you)
Now at the command prompt enter:

ubiquity gtk_ui

Ubuiquity runs as root and the install went perfectly with no problems at all. Only took a couple of minutes to complete. !!
