Setting http_proxy value to local bashrc file
When I connect my laptop to internet from my institute I had to connect it through proxy. But when I connect it from my room I have to connect it directly. So I have to change my proxy frequently. But I have observed that changing proxy through network manager does not actually change the value of "http_proxy" variable. Neither the export command actually work. So we have changed the value by changing the ~/.bashrc file and adding the proxy value. Use the following command to edit file. $gedit ~/.bashrc Then add the following line http_proxy="http://userid:pass_word@proxy:port/" https_porxy="https://userid:pass_word@proxy:port/" ftp_proxy="ftp://userid:pass_word@proxy:port/" You can also set the domain which should not use proxy by no_proxy environment variable. This will be coma separated string containing domain name. Like no_proxy="first.domain,secon.domain" you can also edit some other file like /etc/environment /etc/bash...
