Http 1_1 407 Proxy Authentication Required Curl
curl through authenticated proxy and authenticated http resource
I want to do a post (twitter in this case) with a oneliner.
If I don’t have proxy
curl -u user:pass -d status=”message”
works perfectly.
But when I am behind a authenticated proxy it doesn’t.
I had tryied:
curl -X proxy:port -U proxyUser:proxyPass -u user:pass -d status=”message”
That it jump me with an
proxy do not support basic auth
So do you know what I am doing wrong?
thanks in advance.

Cababunga’s answer is correct, but they’re missing another option: –proxy-ntlm. Some proxies won’t authorize correctly with –proxy-anyauth, so ideally you’ll want to specify the authentication method that your proxy uses. If you run curl -v -U user:pass -x proxy:port –url, you should get something along the lines of the following:
About to connect() to proxy [your proxy] port [your port] (#0)
Trying [IP]…
connected
Connected to [your proxy] ([IP]) port [your port] (#0)
Establish HTTP proxy tunnel to Proxy auth using Basic with user ‘[user]’
CONNECT HTTP/1. 1
Host: Proxy-Authorization: Basic [gibberish]
User-Agent: curl/[ver] ([OS]) libcurl/[ver] OpenSSL/[ver] zlib/[ver]
Proxy-Connection: Keep-Alive
HTTP/1. 1 407 Proxy Authentication Required
Proxy-Authenticate: NEGOTIATE
Proxy-Authenticate: NTLM
Add a flag for whatever you see in the Proxy-Authenticate parameter and you should be good to go. In this example, you would add the –proxy-ntlm flag.

You may be able to put the username/password in the URL for the authenticated resource to avoid having extra command line complications.
also, the –proxy shortcut is a lowercase x, as cababunga pointed out.
curl -x proxyaddr:port -U proxyUser:proxyPass -u user:pass -d status=”message”

Try to add –proxy-digest or –proxy-anyauth.
And I think to connect to proxy you should use lower case -x (not -X).

You may want to try using SOCKS v5 instead of v4:
$ curl –proxy socks5proxyUser:proxyPass@proxy:port…

I managed to perform this with the help of the Micah’s answer here:
this is the command I got at the end to access a BitBucket repo:
curl -u userBitbucket:PwdBitBucket -U userProxy:pwdProxy -x address_proxy:port:proxy –proxy-ntlm host:port/projects/project/repos/repo/browse/file

Using cURL with a Proxy Server – Stefan Bruhns
If you are located inside a network that uses a proxy and authentication for making HTTP requests
to external servers, you need to pass proxy parameters and authentication credentials when using
cURL with a proxy server. I used cURL on macOS Sierra for the examples here. An alternative to using
cURL’s proxy options is to use environment variables. You can read about that approach using the
link below.
In the following examples, I am using the parameters shown in table 1. The Yahoo Finance API
URL returns stock data in JSON format.
Active Directory Domain
ABC
URL
Table 1: Values used in this post’s examples
Example 1: HTTP GET Request via Proxy without Authentication
The simplest command, using cURl’s -x option to specify a proxy server that does not require authentication is:
curl -x
If the proxy server uses a port other than the standard HTTP port, you must append it to the hostname with a colon:
Example 2: HTTP GET Request via Proxy with Authentication
If the proxy requires authentication with a username and password,
use the -U option and separate the values with a colon.
Note that special characters such as the @ character need to be
escaped with a backslash character.
curl -U dave:P@ssW0rd -x
The backslash character needs to be escaped as well. So, for passing a network domain name in the
-U option, use \.
curl -U ABC\dave:P@ssW0rd -x
Additional special characters that need to be escaped with a backslash are listed in the following table.!

Example 3: Setting Proxy Authentication Scheme
In the previous example, the Basic authentication scheme was used by default. If your proxy requires
NTLM authentication, it can be specified using the –proxy-ntlm option.
You can also use the –proxy-anyauth to let cURL determine the proxy
authentication scheme by evaluating the 407 response of the proxy.
curl -U ABC\dave:P@ssW0rd -x –proxy-ntlm
Debugging cURL HTTP Requests with Verbose Option
Use the -v option so that cURL prints out verbose information while running.
This can be used for evaluating the HTTP request and response exchanges between cURL and the proxy.
bash-3. 2$ curl -U dave:P@ssW0rd -v -x * Trying 10. 89. 4. 75…
