Hello,

Today I wanted to make a summary of the different proxy connections possible on Linux ...

All Linux software using proxy variables include: 

  http_proxy, ftp_proxy, HTTP_PROXY, FTP_PROXY

So you must add them to / etc / .bashrc for your environment or / etc / profile for the entire system.

The lines to be added to connect to a proxy is simple: 

  export http_proxy = http://proxy.nom.de.domaine:port
 export ftp_proxy = http://proxy.nom.de.domaine:port
 export http_proxy = http://proxy.nom.de.domaine:port
 export FTP_PROXY = http://proxy.nom.de.domaine:port

The lines to be added for a secure connection to a proxy are: 

  export http_proxy = @ http://user:password proxy.nom.de.domaine: port
 export ftp_proxy = @ http://user:password proxy.nom.de.domaine: port
 export http_proxy = @ http://user:password proxy.nom.de.domaine: port
 export FTP_PROXY = @ http://user:password proxy.nom.de.domaine: port

After you log back, test your variables with: 

  echo $ http_proxy
 echo $ ftp_proxy
 echo $ HTTP_PROXY
 echo $ FTP_PROXY

If like me you work for a company that uses an ISA proxy with authentication in the field, you'll get an error such as "access denied" is returned by the proxy.

Here's how to do with Linux ...

The ISA proxy authenticates connections to the proxy via "the field", the " More>
