These DNS queries are not harming anything, they are coming from background processes in Jenkins checking for things like documentation (for plugins, from the wiki) and core/plugin updates (from the Update Center). If you don't want them to hit your DNS server, you can put entries into an /etc/hosts files on the machine where Jenkins is running that map these specific DNS names into some blackhole IP address (even 127.0.0.1 would be fine).
----- Original Message ----- From: jenkinsci-users@googlegroups.com To: jenkinsci-users@googlegroups.com At: Jan 7 2014 21:26:25 I am currently trying to deploy Jenkins in an environment that will never have a connection to the internet. We have a DNS server on the network that handles all the internal traffic. After installing Jenkins I have noticed that this DNS server is bombarded with requests for resolving things like wiki.jenkins-ci.org and updates.jenkins-ci.org. Additionally I have to manually install plugins which each add another layer of requests seen. These request happen whenever an action is preformed in the web application or upon page refresh. And from what I can tell they are all being received by the DNS server on port 53. I don't think that configuring a HTTP Proxy is the solution in this case, as the internet will never be accessible. Is there some way to stop these requests from Jenkins internally? Or should I be looking at some other solution, like adding a rule to the firewall somewhere? All the machines on the network are running various versions of CentOS. I am using Jenkins version 1.545. I have to admit that I am a newbie to Jenkins and if this answer exists somewhere else I have not seen it. Any help would be greatly appreciated. If I need to provide more information please let me know. John-- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
