Description Olivier Thomann CLA 2016-07-14 14:12:00 EDT
I opened bug 497928. It looks like the issue is that we can no longer ssh to eclipse.org machines. This is a blocker for us to get new builds being deployed on orion.eclipse.org.
Comment 1 Olivier Thomann CLA 2016-07-14 14:52:05 EDT
I think it stopped working around 12:00 yesterday. The latest build is {"build":"2016-07-13_11-00-50"}
Comment 2 Mikaƫl Barbero CLA 2016-07-14 15:44:19 EDT
It may be related to https://dev.eclipse.org/mhonarc/lists/cross-project-issues-dev/msg13352.html
Comment 3 Olivier Thomann CLA 2016-07-15 09:12:46 EDT
Maybe, but none of the builds after the last one mentioned in comment 1 has been properly pushed to orion.eclipse.org. So maybe some services have not been restored after the outrage on the 14th.
Comment 4 Olivier Thomann CLA 2016-07-15 10:30:33 EDT
Any ETA for us on this? I really would like to see orion.eclipse.org being updated with a newer build than the one from July 13th.
Comment 5 Silenio Quarti CLA 2016-07-15 14:01:43 EDT
This issue has been resolved. We had to update the known_hosts file for the admin user in build.eclipse.org.
Comment 6 Olivier Thomann CLA 2016-07-18 18:01:32 EDT
Reopening. The build https://hudson.eclipse.org/orion/job/orion-node/600/ had the same failure again. It looks like the ssh connection is not reliable.

Silenio, is there something that can be done to improve this?

> ssh: Could not resolve hostname orion.eclipse.org: Name or service not known

This is a DNS issue that was caused by temp maintenance.  It's been fixed now. Apologies for the inconvenience.
Comment 8 Silenio Quarti CLA 2016-07-20 10:20:59 EDT
This is still happening. It is intermittent. Usually ssh fails the first time and works after that (see below).  The problem is that, in our build, we only attempt to ssh once, so the build is not deployed. Take a look at (https://hudson.eclipse.org/orion/job/orion-node/609/console) towards the end of the log.

Comment 9 Silenio Quarti CLA 2016-07-20 16:32:27 EDT
We changed our build scripts to use the IP address of orion.eclipse.org to work around this problem.  Hopefully this ip does not change often.
Comment 10 Eclipse Webmaster CLA 2016-07-26 16:08:05 EDT
The IP should be fairly 'static'.  Here the issue was one of the DNS slaves was failing to update so it was causing the resolution to fail every time it was asked.  That has been resolved.
