Forwarding requests not working

Merten | Last updated: Oct 15, 2019 09:34AM UTC

Hey folks, yesterday i noticed that i am not able to forward requests through the burp (it worked a month ago or so). I tried it in 2 Kali VMs and 1 ubuntu 1904. The proxy in firefox and burp are configured. The requests i send are intercepted but not forwarded - the Intercept tab stays empty but the browser is loading a long time until Burp return "Reply from SOCKS server has bad version". Screenshots i made: https://imgur.com/a/SdbaCqH Any tips how to fix this? Regards

Hi Breph, Thank you for your message. Do you have the SOCKS Proxy option enabled within User options -> Connections of the Burp instances that you are using? If so, can you disable this setting by unchecking the Use SOCKS proxy option and then seeing if the intercepting and forwarding of requests now works as expected.

Hi Breph, Not a problem. Glad you were able to get it sorted out in the end.

Hi Mark Could you provide us with a description of your issue, please? Could you also tell me which version of Burp Suite you are using, whether you are using the platform version or the standalone JAR file, and the OS that you are operating on?

I have found a solution that works for me, maybe might work you as well....I have realized burp suite on initial usage, uses the java 11 package which caused the issue for me, I have download the jre 9(latest and then, only it started working properly) 1. sudo wget https://download.oracle.com/otn/java/jdk/9.0.4+11/c2514751926b4512b076cc82f959763f/jre-9.0.4_linux-x64_bin.tar.gz 2. sudo tar -xvzf ~/Downloads/jre-9.*.*.tar.gz -C /tmp/ 3. sudo if [ ! -d "/usr/lib/jvm" ]; then mkdir /usr/lib/jvm; fi 4. sudo sudo chown -R root:root /tmp/jre-9.*.* echo " " 5. sudo chmod -R +x /tmp/jre-9.*.*/bin 6. sudo mv /tmp/jre-9.*.* /usr/lib/jvm/ 7. sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jre-9.*.*/bin/java 1065 8. sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jre-9.*.*/bin/javaws 1065 9. sudo update-alternatives --config java 10. sudo update-alternatives --config javac
