cURL 5 - Proxy not resolved

Question

I am trying to execute the following:

curl twitter.com

But I have got the proxy http://proxyurl:port set in ~/.curlrc

However, when executing curl twitter.com I am getting

curl: (5) Could not resolve proxy: proxyurl

I have tried almost everything such as defining http_proxy in ~/.bashrc

But still no luck.

So two questions, what does it mean by could not resolve proxy,

and secondly how do I resolve it.

Thanks in advance.

@AvalSarri thanks for your reply, the steps in that thread does not help me, but I do have a question, the proxy I made is meant to be a local proxy, meaning the dns wasnt assigned to an ip address, so will I need to add that ip in the hosts file and assign it an IP addy — joh adams

I am not able to understand this, for proxy can you use IP and check instead using a hostname? ping to proxy-ip works? — Aval Sarri

It means you didn't totally remove your proxy. In other words, to be able to resolve it after commenting your settings or deleting the config of your proxy in the ~/.bashrc file, you need to unset the proxy variables by using the following commands:

unset http_proxy
unset ftp_proxy
unset https_proxy

To double check if the proxy is totally removed just execute this command:

env | grep -i proxy
