How do I make curl ignore the proxy?

Question

How do I make curl ignore the proxy? Setting $NO_PROXY doesn\'t seem to work for me.

Answer 1

First, I listed the current proxy setting with

env | sort | less

(should be something like http_proxy=http://wpad.local.machine.location:port number)

Then I tried setting

export http_proxy=";" 

which gave this error message:

curl: (5) Couldn't resolve proxy ';'

Tried

export http_proxy="" && curl http://servername:portnumber/destinationpath/ -d 55

and it worked!

PS! Remember to set http-proxy back to its original settings with

export http_proxy=http://wpad.local.machine.location:port number

Answer 2

I assume curl is reading the proxy address from the environment variable http_proxy and that the variable should keep its value. Then in a shell like bash, export http_proxy=''; before a command (or in a shell script) would temporarily change its value.

(See curl's manual for all the variables it looks at, under the ENVIRONMENT heading.)

Answer 3

Long shot but try setting the proxy to "" (empty string) that should override any proxy settings according to the man page.

Answer 4

My curl was not ignoring the proxy on Ubuntu 12.04 until I set the "no_proxy" (lowercase) environment variable. The --noproxy option was not available.

Answer 5

I ran into the same problem because I set the http_proxy and https_proxy environment variables. But occasionally, I connect to a different network and need to bypass the proxy temporarily. The easiest way to do this (without changing the environment variables) is:

curl --noproxy '*' stackoverflow.com

From the manual: "The only wildcard is a single * character, which matches all hosts, and effectively disables the proxy."

The * character is quoted so that it is not erroneously expanded by the shell.

Answer 6

I have http_proxy and https_proxy are defined. I don't want to unset and set again those environments but --noproxy '*' works perfectly for me.

curl --noproxy '*' -XGET 172.17.0.2:9200
