Title: Name resolution not working for web.mail.mil
Post by: DanB35 on July 04, 2015, 10:26:35 PM

I'm thinking this looks like a bug, but wanted to see if there's anything obvious I'm missing before I report it.  My SME 9.0 server doesn't seem to be able to resolve web.mail.mil.  If I use Google's DNS, it resolves just fine:

Code: [Select]

[dan@e-smith ~]$ host web.mail.mil
;; connection timed out; trying next origin
Host web.mail.mil not found: 3(NXDOMAIN)
[dan@e-smith ~]$ host web.mail.mil 8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:

web.mail.mil has address 156.112.108.149
web.mail.mil.familybrown.org is an alias for familybrown.org.
familybrown.org mail is handled by 0 familybrown.org.I haven't configured any external DNS server on my system.  Where should I be looking, or should I just head over to bugzilla?

Doesn't resolve from here, Oz, from my Win8 system, no sme server involved just by provider iinet. So don't think its a bug in sme server.

familybrown.org does fine..

Had new Internet service installed this morning.  Went from (claimed) 3M down/768k up (which was closer to 150k up) to 50M/10M.  This host now resolves just fine.  I'll chalk this up to a crappy Internet connection.

Well, it resolved fine on Monday.  Today, not so much.  Using my ISP's DNS servers, or Google's, it resolves just fine, but using my SME server itself, nothing:

Code: [Select]

[dan@e-smith ~]$ host web-okcd01.mail.mil

Host web-okcd01.mail.mil not found: 3(NXDOMAIN)

Maybe something has changed?


config show dnscache


config show dnscache.forwarder

Code: [Select]

[root@e-smith ~]# config show dnscache
dnscache=service
    TCPPort=53
    UDPPort=53
    access=private
    status=enabled
[root@e-smith ~]# config show dnscache.forwarder
dnscache.forwarder=service
    status=enabled

I could probably resolve this by just entering my ISP's DNS server in the config console, but I don't think I should need to do that.  I went ahead and submitted a bug: http://bugs.contribs.org/show_bug.cgi?id=8976
