Your site appears to have messed up routing or dns. Manually add a well-known dns such as 8.8.8.8 to your machine to work around the issue. Also verify that your routing and netmask is correct and you can ping arbitrary sites on the internet – try Slashdot.org and news.google.com for instance. Until you get your networking problems corrected, you have little hope of getting any network-aware service like Jenkins functioning correctly.
From: jenkinsci-users@googlegroups.com [mailto:jenkinsci-users@googlegroups.com] On Behalf Of Mohamed Sathack Sent: February-24-15 02:21 To: jenkinsci-users@googlegroups.com Subject: Mirror Sites Hi, I have installed Jenkins in our Linux server which is running with Red Hat OS. I followed the below link for Installation steps https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+RedHat+distributions And now I am trying to install the plugins via Browser. But it is failed with Unknown Host exception. I added an entry into hosts file for that mirror site and downloading it. Again it throws the same exception. Every time it is connecting to different mirror sites. Note: I have another instance of Jenkins which is hosted in my local desktop (Windows 7). I am able to download the plugins in my local desktop instance. When I checked this with our NOC team, they clearly mentioned that NO for disabling firewall What are the other options I have to install those plugins?
