Description Michael Mol 2013-02-26 04:15:29 UTC 
While looking for a way to get a dump of a zone, I ran:

samba-tool dns query kaylee firefly.michael.mol.name '*' ALL


Here's the result:

$ samba-tool dns query kaylee firefly.michael.mol.name '*' ALL
Password for [administrator@FIREFLY.MICHAEL.MOL.NAME]:
ERROR(runtime): uncaught exception - (8, 'WERR_NOMEM')
  File "/usr/lib64/python2.7/site-packages/samba/netcmd/__init__.py", line 175, in _run
    return self.run(*args, **kwargs)
  File "/usr/lib64/python2.7/site-packages/samba/netcmd/dns.py", line 974, in run
    None, record_type, select_flags, None, None)


I have 10GB of RAM on that box, 7GB that's free or disk cache.

This is a problem with wild-card search.

If you want to search the entire zone, please use @ instead of '*'.

We should return WERR_DNS_ERROR_NAME_DOES_NOT_EXIST (as windows)
instead of WERR_NOMEM...

Upstream already has a patch to netcmd/dns.py to dump correct message in case user specifies * in the name.

I think we should also fix the server.

Ping!

That patch was effectively reversed with 29b3a2b0d1e5abc1ca9f112f680251e34fa6e3af as part of the fix for bug #12952 ("Samba DNS server does not honour wildcards").

The fix for bug #12952 entails the server fix mentioned in comment 4.

Now in a testenv I see:

$ bin/samba-tool dns query -U$USERNAME%$PASSWORD $SERVER addom.samba.example.com '*' ALL
use "@" to dump entire domain, looking up *
ERROR: Record or zone does not exist
