Installing SNMP through the Command Line – Part 2

Anthony Reinke — Wed, 01 Feb 2012 22:01:19 +0000

I added a batch script I wrote to install SNMP on a bunch of machine back on Jan. 14, 2012 (http://www.anthonyreinke.com/2012/01/14/installing-snmp-through-the-command-line/). I have since modified the script. Changing the file from a .bat to a .cmd will allow you to right click and run as administrator on Windows 2008. Also I noticed in 2008, it defaults in to having the localhost as the only system that can communicate to the SNMP Service.

PsExec.exe @hosts.txt -s -c installsnmp.cmd

Below is the file to download. Rename the file to installsnmp.cmd
installsnmp.cmd.txt

As always, please contact me if you have questions.

Installing SNMP through the Command Line

Anthony Reinke — Sun, 15 Jan 2012 04:18:59 +0000

I needed a way to mass install SNMP to the servers in my environment. The problem I was having was Microsoft Windows Server 2003 needing files from the CD. We don’t copy the i386 directory from the CD for two reasons. We store the files on the network and drive space is limit on a lot of servers. The batch script will check if the server is 2003. If it is 2003, it will point the install cd to a network path or a local path. Next it builds the unattended install file. Once the file is written, the system will add the SNMP feature per the unattended file. After SNMP is installed, the registry keys are set for the SNMP community strings. Lastly the script removes the temporary files it created.

Use this script in combination to PSTools’ PSExec and you can mass install. Create a list of systems you want to install this on and call it hosts.txt. Each server needs to be on it’s own line and it is best to use the fully qualified name or IP Address. Copy the hosts.txt and installsnmp.bat file in to your PSTools directory and run the following command:

PsExec.exe @hosts.txt -s -c installsnmp.bat

Download the Install SNMP Batch File, just rename to a .bat file.

Monitoring the Filesystem with Splunk

Anthony Reinke — Mon, 31 Aug 2009 19:17:06 +0000

I have used OSSEC in the past to watch the file system for changes. When I found that I can have the Splunk agent handle the monitoring itself, I was pretty excited. Since I would send my OSSEC data to Splunk anyways, it just seemed logical to have Splunk do everything.

In Windows, you need to edit the “c:program filesSplunketcsystemlocalinputs.conf” file. Of course your path could be different if you installed it in a different place. There are a lot of options and switches you can use. I went for the simplest set.

[fschange:d:temp]
recurse=true
pollPeriod=3600

This will monitor the d:temp folder and all files and folders under it. It will check the system every 3600 seconds (1 hour).

This has helped me keep track of the changes in my servers. I can see when a file was add/deleted/changed (due to the hash) and then look at who was logged in during the period that the file was changed.

[fschange:d:temp]

Life as a G33k

Anthony Reinke — Sun, 21 Jun 2009 04:56:41 +0000

I am sitting here on my main desktop writing this. On one tab of FireFox I have my Facebook open. On the next tab I have this page open. I have my uTorrent runningin the background. My laptop sits next to me with a VPN connection in to work. I am running scripts and adding accounts in to group and verifying that the servers got the correct grouping. My IDS is humming along. My ESXi server is pumping out the heat as the server tries to keep the 8 processors cool. I have 4 IM windows up on the laptop and 3 chat windows in facebook. I have 7 command prompt windows pinging servers asking them if they are still up.

It is now 1:35am and I have been up since 5:30am the day before. No worries, I got my energy drink (Monster Khaos). Odds are I will be in to work between 9 and 10am. Why? Because I have 40 tickets to complete and more to be assigned.

Such is the life of a geek.
