# cc -V

cc:  1501-273 A mismatch exists between the OS level and the configuration file. The configuration file /etc/vac.cfg is intended for AIX 5.3. Use vac.cfg.61 to correct the problem.

What?

# ls -la /etc/ |grep vac

lrwxrwxrwx    1 root     system           10 Jan 18 08:51 vac.cfg -> vac.cfg.53
-rw-r--r--    1 bin      bin           32781 Jan 16 10:23 vac.cfg.50

-rw-r--r--    1 bin      bin           37045 Jan 16 10:23 vac.cfg.53

Not there. Okay...

# cp vac.cfg.53 vac.cfg.61
# vi vac.cfg.61

Remove the last lines:

oslevel   = 5.3
os_major  = 5
os_minor  = 3

Done.

# ln -s vac.cfg.61 vac.cfg
# chown bin.bin vac.cfg.61

I win.

good times with system inventories

i heart lists. i really do.

i have lots and lots of lists. sometimes people send me lists asking me to do things with things on lists. one of my favorite sorts of lists is an inventory list. i like to know what i have.

one day, say today, someone asked me to turn off a scad of systems that were on a list. it was a long list. but some things on the to-be-turned-off list were not on my list. how do i figure out what is mine or not?

sort and awk are my friends.

sort mysystems.txt maybemysytstems.txt | awk 'seen[$0]++ == 1' > systemsonbothlists.txt

and there you go.

samba wins flags

because it is fun making linux machines pretend they're nt4 boxes.
edit /var/lib/samba/wins.dat for fun and profit:

wins flags for NetBIOS

On the WINS server, there is a NetBIOS name for each service a NetBIOS computer offers. This uses the 16th hidden character of the NetBIOS names.  The same flags are used in lmhosts entries.

The characters and their meanings are:

 00 - Workstation service (Domain name) or (Workgroup name) or (Computer name)
 03 - Messenger service (Computer name) or (User name)
 06 - RAS server service (Computer name)
 1B - Primary domain controller (Domain name)
 1C - Domain controller or PDC or BDC (Domain name)
 1D - Master browser (Domain name)
 1E - servers only; indicates the computer would become a browser if requested.. (Domain name) or (Workgroup name)
 1F - NetDDE service (Computer name)
 20 - Server service (Computer name)
 21 - RAS client (Computer name)
 BE - Network Monitoring Agent service (Computer name)
 BF - Network monitor utility service (Computer name)

here's a nice snippet of wins.dat for a domain. the zilch means permanent record.

"AWESOME#1d" 0 192.128.80.22 e4R
"AWESOME#1e" 0 255.255.255.255 e4R
"AWESOME#1b" 0 192.128.80.22 e4R
"AWESOME#1c" 0 192.128.80.22 e4R
"AWESOME#00" 0 255.255.255.255 e4R

1d is very important if you want other systems that are using wins to not preempt the domain master browser if their os is "higher."
