How to enable or disable DNS updates in Windows 2000 and in Windows Server 2003 - http://support.microsoft.com/kb/246804  (Good KB on how DNS updates are performed)


How to configure DNS dynamic updates in Windows Server 2003 - http://support.microsoft.com/kb/816592/
When one of these events triggers a DNS update, the DHCP Client service, not the DNS Client service, sends updates. If a change to the IP address information occurs because of DHCP, corresponding updates in DNS are performed to synchronize name-to-address mappings for the computer. The DHCP Client service performs this function for all network connections on the system. This includes connections that are not configured to use DHCP.



If you use multiple Windows Server 2003-based DHCP servers on your network and if you configure your zones to enable secure dynamic updates only, use the Active Directory Users and Computers snap-in to add your DHCP server computers to the built-in DnsUpdateProxy group. When you do this, all your DHCP servers have the secure rights to perform proxy updates for any one of your DHCP clients. For more information, see the "Using DNS servers with DHCP" topic or the "Manage groups" topic in Windows Server 2003 Help.

Citrix Metaframe client hangs

If the Citrix Metaframe client hangs after it says "connection established", "negotiating capabilities", then upgrade to version 9 or higher.  I think there are some issues running version 8.00.24737 as a "regular" or restricted user and not an administrator or power user.

STP on TruCluster NICS

Any NICs in a Tru64 TruCluster environment, whether they be the cluster interconnect or the regular public lan NICs, should have spanning tree protocol (STP) turned off on the port they are connected to. See the TruCluster Server Cluster Administration guide (part number: AA-RHGYE-TE

On a Cisco switch, in enable mode:

config t
interface FastEthernet0/1
no spanning-tree portfast

Don't forget to save the running config to nvram.

Remove the drunk monkey logo

Has this ever happened to you?:  one day you reboot your Windows 2000 machine to find that the default blue background at the control-alt-del screen has been changed to a white background with 3 drunk monkeys at the bottom of the screen.  For some odd reason this also coincides with departure of a former employee.  Curious huh?

 

Anyway to get rid of the monkeys, look in

HKEY_USERS\.Default\Control Panel\Colors

 

copy the value of Background_old to Background

 

in

HKEY_USERS\.Default\Control Panel\Desktop

 

copy the value of Wallpaper_old to Wallpaper

 

You can also get rid of the C:\winnt\drunk_logo.bmp file.

Get AlphaServer SRM console version

To get the SRM console version (firmware) on an Alpha Server via a shell:

consvar -g version

Output will be something like this:

version = V7.0-3 Jun 16 2005 14:53:11

 

Get some more detailed info with the first two lines of output:

# consvar -v -l
Firmware Rev: 7.0-3
system fam:38  cpu:8  smm:1978

 

get the PALcode similarly:

consvar -g pal

 

Output will be something like this:

pal = OpenVMS PALcode V1.98-43, Tru64 UNIX PALcode V1.92-33

Remove formatting from man pages

To remove the formatting from man pages so that you can redirect them to text and view in vi or another editor you can create a shell alias and associated script:

 

alias mantext='~/bin/mantext.ksh'

 

mantext.ksh:

man $1 | sed -e 's/.//g'

 

Now use mantext instead of man when redirecting a man page to a file.

cron deficiencies

I was told to make a process run the first day of every month, but cron doesn't have the "smarts" to do it.  I found the following solution to be adequate:

From: http://www.darklab.net/resources/hpux-mailinglist/0715.html

DO SOMETHING ON THE LAST DAY OF A MONTH
 
Unfortunately, cron does not give us a simple way to say
'run this on the last day of month'. Fiddling with the
different length months, leap years, y2k bugs and so on is
messy. Here's a simple solution that gives all the dirty
work to some well tested utility. The idea is to check whether
*tomorrow* is the first day of a month.
 
Solution 1 (using date, change MET to your local time zone)
 
#!/bin/sh
if test `TZ=MET-24 date +%d` = 1; then
   # today is the last day of month
fi
 
You can call this script from cron, say with a crontab of
4 2 28-31 * * /path/to/your/script
