samba & static wins entries
yes. you need to think about this from time to time.
Static WINS Entries
Adding static entries to your Samba WINS server is actually fairly easy. All you have to do is add a
line to wins.dat, typically located in /usr/local/samba/var/locks or /var/run/samba.
Entries in wins.dat take the form of:
"NAME#TYPE" TTL ADDRESS+ FLAGS
where NAME is the NetBIOS name, TYPE is the NetBIOS type, TTL is the time-to-live as an absolute
time in seconds, ADDRESS+ is one or more addresses corresponding to the registration, and FLAGS
are the NetBIOS flags for the registration.
A change that has been made to the wins.dat will not take effect until nmbd has been restarted.
It should be noted that since the wins.dat file changes dynamically, nmbd should be stopped before editing
this file. Do not forget to restart nmbd when this file has been edited.
A typical dynamic entry looks like this:
"MADMAN#03" 1155298378 192.168.1.2 66R
To make a NetBIOS name static (permanent), simply set the TTL to 0, like this:
"MADMAN#03" 0 192.168.1.2 66R
The NetBIOS flags may be interpreted as additive hexadecimal values:
00 - Broadcast node registration
20 - Peer node registration
40 - Meta node registration
60 - Hybrid node registration
02 - Permanent name
04 - Active name
80 - Group name.
The 'R' indicates this is a registration record.
Thus 66R means: Hybrid node active and permanent NetBIOS name. These values may be found in the
nameserv.h header file from the Samba source code repository. These are the values for the NB flags.
nameserv.h
92 /* The wins flags. Looks like the nbflags ! */
93 #define WINS_UNIQUE 0x00 /* Unique record */
94 #define WINS_NGROUP 0x01 /* Normal Group eg: 1B */
95 #define WINS_SGROUP 0x02 /* Special Group eg: 1C */
96 #define WINS_MHOMED 0x03 /* MultiHomed */

finding orphaned vmware templates or vmtx hell
what happens when templates and parent directories haven't consistent names or reside in
directories that share the same name, and of course, are all over the place? you sigh.
then you "open the book". and when i say "open the book" i mean it the way
the portuguese mean it. think sailor talk, only worse.
vmware isn't very nice in that via vsphere you can't figure out where your "assets" reside.
that's *okay*. gui fail.
various powershell cli scripts are losers, too. what you need to do is actually query
the sql db that the vcenter uses.
so, off i go to vmware's support site; and i find this:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2004139
COOL. install more junk on my system. since this is running sql server 2008 express,
i get this:
http://www.microsoft.com/en-us/download/details.aspx?id=7593
flock. i go through the totally non-intuitive install for sql server 2008 studio express.
just install "a new instance". you're not really installing sql server 2008. i cancelled
when i saw that under installation. i read up. and the i went for it. no worries.
and then you run the tool.
of course you've kept the name of your db and passwords handy, right?
well, if you went with the vmware defaults, just to a network browse, connect to your
local sql server express db. it should look like: YOUR_VCENTER\VIM_SQLEXP
and do local auth. it is okay.
you run this query that vmware support gave you:
select VPX_ENTITY.NAME as "VM Name", VPX_VM.FILE_NAME as "File Name / Path"
From VPX_VM inner join VPX_Entity
where VPX_VM.FILE_NAME LIKE '%VMNAME%'
on vpx_vm.ID = vpx_entity.ID
order by VPX_entity.name;
it barfs. holy heck. re-write the query and get expected results:
use VIM_VCDB;
select VPX_ENTITY.NAME as "VM Name", VPX_VM.FILE_NAME as "File Name / Path"
From VPX_VM inner join VPX_Entity
on vpx_vm.ID = vpx_entity.ID
order by VPX_entity.name;
and there you go. of course the datastores are completely unfriendly,
but you can ssh into your client boxes and figure it out pretty quick.
of course you can.
go get some coffee. you're awesome.

old linux box old samba join old
Adding a Linux domain member machine
configure the smb.conf file with all happiness. Include workgroup, authentication via domain, etc.
check if config is nifty fine:
% testparm
to check if ldap auth via nsswitch is okay, execute:
%getent passwd
%getent group
join the domain:
% net rpc testjoin -S 'PDC' -U Administrator%yesyes
% net rpc join -U Administrator%oreilly
if errors abound, may need in smb.conf:
client schannel = no
or... just do it again.
afterwards, check if all is fine:
% smbclient -L localhostname
it should show something like:
Anonymous login successful
Domain=[ONTHEPHONE] OS=[Unix] Server=[Samba 3.0.22]
Sharename Type Comment
--------- ---- -------
ADMIN$ IPC IPC Service (bollocks server (Samba 3.0.22))

If the server is a BDC, do not forget to:
% smbpasswd -w

oh the humanity or updating intel nic drivers on esxi 5.5.0
yeah. fun stuff. so vmware, too lazy to update your isos? search through the archives for the correct async ones and unpack the archive and upload the thing called offline-bundle and then scp up to an esxi host - be sure to have ssh service running, is that what you're telling me to do? okay.
~ # esxcli software vib install -d /vmfs/volumes/yes-local/isos/igb-5.2.5-offline_bundle-1682588.zip Installation Result Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective. Reboot Required: true VIBs Installed: Intel_bootbank_net-igb_5.2.5-1OEM.550.0.0.1331820 VIBs Removed: VMware_bootbank_net-igb_5.0.5.1.1-1vmw.550.1.15.1623387

manually umount and mount an nfs volume on esx 5.5
vmware esxi 5.5 says the nfs volume is not accessible. really?
esxcli storage list
yep. not accessible.
esxcli storage nfs remove -v nfs-store
remove it. do whatever you do to fix the issue. then... re-add per below.
esxcli storage nfs add -H 192.168.6.66 -s /data/dev/nfs-store -v nfs-store
^ ^ ^
