Couchbase Server

DNS lookups don't work on Windows

    Release Note

Description

If I try to join another node by specifying the hostname of the server instead of using dotted decimal I get an error message saying:

'Attention - Failed to resolve address for "windows". The hostname may be incorrect or not resolvable. '

I am able to run the following command from cmd.exe:
C:\Program Files\NorthScale\Developer Kit\bin>nslookup windows
Server: speedtouch.lan
Address: 10.0.0.1

Name: windows.lan
Address: 10.0.0.28

I remember MB-204, but it was a different issue. The resolution on 320 had to do with the way we were dropping in and installing erlang I believe.

In any event, I will try some hostname resolution after getting through BAT right now. I'm confident menelaus is doing the right thing, but there may be a case that erlang isn't handling.

This may be P3able, if it only resolves when using fqdn. Did you try that by chance?

Aliaksey, I think this should be probably fixed "for free" as part of delayed IP addr assignment enhancement.

Not sure. I've been using hostnames instead of addresses since cluster joining was working. And at least on linux erlang is resolving names via libc name service switch facility (i.e. usual gethostbyname, not some kind of home brewed async DNS resolver), so that mDNS names (like epsilon.local) work too.

So this should be something win-specific, I guess.

Assigning to our QA department for testing. Thuan, can you check this out specifically on Windows?

The issue is reproduced.
Node with names w2008x64qa.altoros.corp or w2008x64qa were not added though the node is accessible through web using this names.
UI error: Attention - Could not connect port mapper at "w2008x64qa" (tcp port 4369). With error Reason nxdomain. This could be due to firewall configured between the two nodes.

Log is attached.

erlang on windows clearly has issue with name resolution:

Erlang web shell 0.01 (dennis:killme2008@gmail.com)
1> inet:gethostbyname("google.com").
{error,nxdomain}
2> inet:gethostbyname("localhost").
{ok,{hostent,"localhost",[],inet,4,[{127,0,0,1}]}}
3> inet:gethostbyname("gwwin.altoros.corp").
{error,nxdomain}

pinging from cmd.exe to gwwin.altoros.corp and google.com works.

There's no time to fix name resolution on Windows - this problem is not specific to us and there's not an easy fix.

The Erlang link seems to indicate that this issue is fixed. Can we import that into our Erlang?
