chaos-lab server is not reachable

Project Member Reported by shahy@google.com, Aug 11 2017

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.90 Safari/537.36

Steps to reproduce the problem:
1. ping the system - 172.22.39.251 fails
2. create an ssh tunnel - fails
ssh -L 5905:localhost:5900 root@172.22.39.251 -nNT

3. both the above failures are sporadic, sometimes the server network is up, sometimes it's down resulting in interference with test execution

What is the expected behavior?
The network should always be up allowing for remote management using vnc viewer.

What went wrong?
network failure

Did this work before? N/A

This bug probably belongs with chromium > Infra, but I am not getting an option to change the component or cc anyone to this bug.

This is nothing that infra labs supports, I assume probably the chromeos lab?

Seems like this is fixed now. The problem was that:

$ nslookup chromeos3-chaosvmmaster.cros.corp.google.com

Was returning address: 172.22.39.250 for some machines and 172.22.39.251 for others. It might be caused by a dns cache problem.

Yash,

Please take a look and see if this is fixed now for you too.

172.22.39.251 is still not reachable for me.

nslookup gives me the following:

$ nslookup chromeos3-chaosvmmaster.cros.corp.google.com
Server:		127.0.1.1
Address:	127.0.1.1#53

Non-authoritative answer:
Name:	chromeos3-chaosvmmaster.cros.corp.google.com
Address: 172.22.39.250

Status: Fixed (was: Unconfirmed)
The hostname is resolving to the correct ip now: 172.22.39.250
