# Week 42 - ProxyChains

Running into issues getting your HTTP requests to play nicely with your [#AppSec](https://www.linkedin.com/feed/hashtag/?keywords=appsec\&highlightedUpdateUrns=urn%3Ali%3Aactivity%3A6993911566785986561) tools?\
 \
I’ve encountered connection/request/formatting problems with tools like SQLMap, EyeWitness, Hydra and especially custom python scripts. Most of the time, it's because I forget to add a matching quote or a necessary request header.\
 \
My favorite way to debug these issues is to proxy the tool through BurpSuite! Some tools (like SQLMap) have this feature available as a command (--proxy). But what happens when they don’t?\
 \
Use ProxyChains! It’s super simple to setup (see screenshot) and will save you a ton of time when trying to figure out why your HTTP Requests are not working as planned. Just change the last line of the ‘/etc/proxychains4.conf’ file to:\
 \
`http 127.0.0.1 8080`\
 \
This will tell proxychains to send our traffic through an HTTP proxy on localhost port 8080 (where Burp is listening). Then prefix your tool command with proxychains4 (EX: proxychains4 sqlmap -u target\[.]com) and you’re good to go!\
\
Burp will intercept all HTTP requests allowing you to send them to the repeater and see what you accidentally left out :)
