SNMP on OpenSolaris

admin — Thu, 27 Aug 2009 14:46:05 +0000

SNMP is not installed by default on Open Solaris but really easy to set up. You don’t need to compile it from source as some would suggest.

All you’ll need is to install the SUNWsmmgr package.
pkg install SUNWsmmgr
All of the config files, including snmpd.conf are in /etc/sma/snmp.

The service to enable snmp is called sma.
svcadm enable svc:/application/management/sma:default

To install utilities like snmpwalk and snmpget, you can install the SUNWsmcmd package.

Install Office 2003 without a CD key ..sort of

admin — Fri, 24 Apr 2009 20:21:43 +0000

Office 2003 wont install unless you supply a valid license key, unlike Office 2007 which lets you enter the key once you’re done installing. This is very inconvenient when you’re trying to create a base image of a system to deploy on multiple PCs. You can’t have the same Office license key for all the PCs.

In order to get somewhat similar functionality as Office 2007, i.e., install without key to be filled in later, use the following method. You will still need a valid serial key for the first install, but it will be cleared after its completed.

setup.exe /QB PIDKEY=YOURSERIALHERE regedit /S clear-key.reg

The first line installs office silently with the specified key, and second line clears the registration information. The clear-key.reg file contains the following registry key

Windows Registry Editor Version 5.00 [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\11.0\Registration]

Now when you run Office, it’ll ask you for a license key.

Configuring TCP/IP from the cmd line in Windows

admin — Mon, 16 Feb 2009 15:48:41 +0000

Netsh.exe can be very useful in viewing and editing TCP/IP settings from the command line.

To view your TCP/IP settings in a Command Prompt, type
netsh interface ip show config

To configure an IP address and other TCP/IP related settings:
netsh interface ip set address name="Local Area Connection" static 192.168.1.101 255.255.255.0 192.168.1.1 1

To obtain an IP address from a DHCP server:
netsh interface ip set address "Local Area Connection" dhcp

To configure DNS and WINS addresses:
netsh interface ip set dns "Local Area Connection" static 192.168.0.200

and this for WINS:
netsh interface ip set wins "Local Area Connection" static 192.168.0.200

Or, to dynamically obtain DNS settings:
netsh interface ip set dns "Local Area Connection" dhcp

As a bonus tip, you can export your IP settings to a text file using the following command:
netsh -c interface dump > c:IPSettings.txt

To import the settings, type
netsh -f c:IPSettings.txt OR netsh exec c:location2.txt

You can use this to quickly switch between different settings.
