Linux Curl with Proxy
- Setting proxies to work with cURL is actually easy. Before showing you how to set things up, I need to let you know that most Windows and macOS devices have cURL preinstalled. All you need to do is make use of it. To make use of proxies with cURL, all that is required is a variable in the cURL syntax.
- Using a proxy with Curl is straightforward and flexible. There are a few methods you can use. You can specify the proxy URL on the command line, or set the appropriate environment variable. This is the most straightforward way to use a proxy server with curl. Using the -x option guarantees that you are using the proxy you intend.
What is Curl? curl is a tool to transfer data from or to a server, using one of the supported protocols (DICT, FILE, FTP, FTPS, GOPHER, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3, POP3S, RTMP, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET and TFTP). The command is designed to work without user interaction.
Curl With Proxychains
Using a proxy to connect. Very handy if you are working on the DMZ server where you need to connect to the external world using a proxy. Curl -proxy yourproxy:port Test URL with injecting header. You can use curl by inserting a header with your data to test or troubleshoot the particular issue.
So in the cloud you may find yourself on a server that needs to communicate to an external system but it isn’t allowed to go there directly. In which case you will most likely have a proxy server to communicate through. In PeopleSoft you can define a web gateway proxy server, however, to test to make sure that the server is working correctly with the proxy you will want to do a curl test.
Linux Command Prompt –> curl http://whatsmyip.com
This should return the external IP address of the system you are coming out of. If this returns nothing you are likely blocked from going to that address. So to push the request through the proxy server, you need to set the proxy in an environment variable:
Linux Command Prompt –> export http_proxy=http://myproxy.atmyserver.com:80
Linux Command Prompt –> curl http://whatsmyip.com
Now as long as the proxy is allowed to communicate to that address you should see the IP address of the system you are communicating from.
