592745 - change DNS servers for releng servers

Status: RESOLVED FIXED

(Release Engineering :: General, defect)

Description

[Justin Dow [:jabba]]

Since moving to the new proxy server, which also serves as a DNS cache, there are still some servers using the old server. Please ensure that no servers are using 

10.250.48.7 as their DNS server and change them all to use

10.250.48.16 instead.

Some servers that are still using the old server:

10.250.48.136
10.250.48.137
10.250.48.138
10.250.48.139
10.250.48.236
10.250.48.240
10.250.48.241
10.250.48.246
10.250.48.247
10.250.51.72
10.250.48.186
10.250.51.157
10.250.49.80
10.250.50.174

There might be some others. I think most of these are masters and ref machines or other slaves that haven't rebooted in a long time. My goal is to shutdown this DNS server on Thursday, so all clients should be pointing to the new proxy for DNS.

Theoretically, if any get missed, they'll just time out on their DNS lookups and use the other server in /etc/resolv.conf, but since these are masters, I think having you reconfigure them during the downtime is best.

were all set to use the new dns proxy except:

talos-r3-fed-ref.build.mozilla.org
talos-r3-fed-ref64.build.mozilla.org
talos-r3-fed64-043.build.mozilla.org <-- this one still thinks its a ref image
talos-r3-fed64-053.build.mozilla.org <-- looks like it needs a reboot

and I couldn't log into:

qm-laddon01.build.mozilla.org

and it looks like the reverse dns is busted on:
talos-master02.build.mozilla.com - needs s/.com/.org/

the two broken talos fed64 slaves will be fixed in bug 593033
