• Как выглядит моя система, обратите внимание, что вам придется изменить указанную конфигурацию системы для вашей сетевой среды.

Некоторые системы Linux используют /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/" 

Там нет единой единой настройки другого использования 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/ 

Я хотел бы проверить ~/.bashrc, чтобы настройки применялись автоматически при запуске системы.

$ 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

Can you show me the command line to turn off proxy when I am using the command line terminal in Ubuntu?

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 Proxy Server Settings – Set Proxy For Command Line

To use a proxy on the Linux command-line, you can set the environment variables http_proxy , https_proxy or ftp_proxy , depending on the traffic type.

These proxy server settings are used by the almost all Linux command-line utilities, e.g. ftp , wget , curl , ssh , apt-get , yum and others.

If you don’t know yet which proxy server to use, you can take one from the lists of the free public proxy servers at the end of this article.

Export Proxy Server Settings

Set these variables to configure Linux proxy server settings for the command-line tools:

$ export http_proxy $ export https_proxy $ export ftp_proxy

If a proxy server requires authentication, set the proxy variables as follows:

$ export http_proxy $ export https_proxy $ export ftp_proxy

Special Characters: If your password contains special characters, you must replace them with ASCII codes, for example the at sign @ must be replaced by the %40 code, e.g. p@ssword = p%40ssword .

Test The Proxy Server From The Linux Command-Line

First off all it is required to check that the proxy server settings are set in the corresponding proxy variables.

Than it is required to ensure that your public IP address has changed.

Also it would be interesting to measure and compare response time of the remote resources and the Internet speed with and without proxy.

Check the current proxy server settings:

Check your public IP address from the Linux command-line:

$ wget -q -O - checkip.dyndns.org \ | sed -e 's/.*Current IP Address: //' -e 's/
Compare the difference in the response time with the configured proxy and without it:
$ time wget -q -O - checkip.dyndns.org \ | sed -e 's/.*Current IP Address: //' -e 's/
Check the Internet download speed through the proxy:
$ wget --output-document=\ /dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip
 
Unset Linux Proxy Variables
 
Use the following commands to disable proxy:
 
$ unset http_proxy $ unset https_proxy $ unset ftp_proxy

Automate Proxy Server Settings In Linux
 
If you use the same proxy server settings for the https , http and ftp traffic, you can use the following commands to set and unset the proxy settings:
 
$ export _proxy="http://PROXY_SERVER:PORT" $ unset _proxy
 
If you use a proxy server often, you can create Bash functions as follows (add to your ~/.bashrc file):
 
# Set Proxy function setproxy() < export _proxy="http://PROXY_SERVER:PORT" > # Unset Proxy function unsetproxy() < unset _proxy >
 
Now use the setproxy and unsetproxy commands to set and unset Linux proxy server settings.

How to disable proxy in Google Chrome on Linux
 
 
If you can’t connect to the internet, it is possible that you are using a proxy server. This guide will show you how to disable proxy settings in Chrome on Linux.
 
A proxy server is an intermediary between your computer and the internet. It is often used to hide your real location and helps you access websites that would otherwise be blocked. However, proxies do not offer the same privacy protections as a VPN. If you are using ExpressVPN, there is no need to run a proxy on top of the VPN connection.
 
Preliminary check
 
If you suspect a system-wide proxy setting is preventing you from browsing the internet, try to disable proxy settings in Chrome.
 
Go to Terminal, then enter the following:
 
 
Launch Chrome to see if you can access the internet.
 
If you are able to access the internet again, follow these steps to disable proxy on Chrome permanently, or disable your global proxy settings.
