[SOLVED] Proxy without Desktop Environment

Hey,
I'm trying to set up my laptop running arch to work with network at work.

I got a working settings in /etc/network.d/ and I am able to do a netcfg mynetwork and connect.

Only thing bugging me is proxy. If I set it up inside Opera browser, it's all fine, but I can't access internet from terminal.

Proxy requires authentication.

I followed this article - https://wiki.archlinux.org/index.php/Pr … _variables

If I use this method (I changed the 'proxyserver' to my proxy address):

function proxy(){
     echo -n "username:"
     read -e username
     echo -n "password:"
     read -es password
     export http_proxy="http://$username:$password@proxyserver:8080/"
     export https_proxy="http://$username:$password@proxyserver:8080/"
     export ftp_proxy="http://$username:$password@proxyserver:8080/"
     export no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"
     echo -e "\nProxy environment variable set."
 }
 function proxyoff(){
     unset HTTP_PROXY
     unset http_proxy
     unset HTTPS_PROXY
     unset https_proxy
     unset FTP_PROXY
     unset ftp_proxy
     echo -e "\nProxy environment variable removed."
 }

(which btw I think it contains an error, flag for 'read password' should be just -s)

and I run a proxy (after sourcing it and typing in username and pw) I get a "Proxy environment variable set."
But when I try to ping something, it just hangs.

The second method (I changed username and serveraddress:port):

#!/bin/bash

 assignProxy(){
   PROXY_ENV="http_proxy ftp_proxy https_proxy all_proxy no_proxy HTTP_PROXY HTTPS_PROXY FTP_PROXY NO_PROXY ALL_PROXY"
   for envar in $PROXY_ENV
   do
     export $envar=$1
   done
 }

 clrProxy(){
   assignProxy "" # This is what 'unset' does.
 }

 myProxy(){
   user=YourUserName
   read -p "Password: " -s pass &&  echo -e " "
   proxy_value="http://$user:$pass@ProxyServerAddress:Port"
   assignProxy $proxy_value  
 }

gives the following error:

assignProxy:export:4: not valid in this context: http_proxy ftp_proxy https_proxy all_proxy no_proxy HTTP_PROXY HTTPS_PROXY FTP_PROXY NO_PROXY ALL_PROXY

So, what is my next step?
Thanks

Ping is not a way to test proxy connections (well, you can test if the proxy answers your ICMP requests, but nothing more). Use curl or wget or anything the does a HTTP request and is aware of proxies.

Re: [SOLVED] Proxy without Desktop Environment

Oh, ok. I tried wget after I did a proxy() (first script listed above), entered username, password, and got a "Proxy environment variable set." and then I get this:

Error parsing proxy URL http://:MYPASSWORD@10.0.4.25:8080/: Invalid user name.

It seems to me that there is something wrong with the script - even though it asks me for username, it doesn't make an environment variable with it.
My user name is in the form "domain/name.surname", but I tried a 'simpler' one - "test", and it still sets the environment variable without it.

I can't find error in script...

edit: I tried to do it manually too:

export http_proxy="http://name:password@ip:port/"

and then tried a wget - it complains

ERROR 407: Proxy Authentication Required.

Re: [SOLVED] Proxy without Desktop Environment

Ok, got it sorted out.
First I used printenv command to see what exactly is set...and then I figured out that the correct way to enter username is:

domain\\username:password

One has to escape the "\" after domain...
wget worked.

Marking as solved, thanks.

btw, script still doesn't work for me...will have to look into that

edit: since I use proxy only at work (for now), I tweaked the script not to ask for username and password - I made a function proxywork() with everything set up. When (if) I have to use some other proxy, I will add another function "proxy2()" or something...and I left one unique proxyoff() function to remove all variables.
