Michael, I tried following your blog post: https://jenkins.io/blog/2019/01/07/webhook-firewalls/
I did the following additional steps not in your blog post using a Jenkins 2.190.2 server: 1. I configured the smee endpoint, https://smee.io/myendpoint 2. I ran the smee client, which just sits there, and waits for notifications on https://smee.io/myendpoint , and then forwards these notifications to http://localhost:8080/github-webhook/ using this script: *#!/bin/sh URL=https://smee.io/myendpoint <https://smee.io/myendpoint> SMEE=/Users/craigrodrigues/smee/node_modules/smee-client/bin/smee.js TARGET=http://localhost:8080/github-webook/ <http://localhost:8080/github-webook/> $SMEE --url $URL --target $TARGET* 3. I configured a webhook on my GitHub repository to connect to https://smee.io/myendpoint 4. I do a git push to my github repo 5. GitHub does a POST on https://smee.io/myendpoint 6. Smee client forwards that post to http://localhost:8080/github-webhook/ On my Jenkins server, I had to configure this: [image: image.png] After doing a *git push*, if I look in the logs of the smee client, I see: * status: 403, text: '<html>\n' + '<head>\n' + '<meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>\n' + '<title>Error 403 No valid crumb was included in the request</title>\n' + '</head>\n' + '<body><h2>HTTP ERROR 403</h2>\n' + '<p>Problem accessing /github-webook/. Reason:\n' + '<pre> No valid crumb was included in the request</pre></p><hr><a href="http://eclipse.org/jetty <http://eclipse.org/jetty>">Powered by Jetty:// 9.4.z-SNAPSHOT</a><hr/>\n' + '\n' + '</body>\n' + '</html>\n', method: 'POST', path: '/github-webook/' },* So it looks like in order to access http://localhost:8080/github-webhook/ , I need to pass some sort of authentication in order to access that URL. How did you configure this in your setup? -- Craig -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
