SNMP with CygWin

I love CygWin. I helps me to combine the best of 2 worlds, the easy of use and convenience of Windows and the command line functionality of Linux. (This statement is blasphemy in some circles. I know). The challenge though is that sometimes it is difficult to have all the tools you need without first connecting to a Linux box, especially for times when this is not possible.

This is one example. I needed snmpwalk but it was not installed on the Linux boxes at my disposal. This is how I got it working in CygWin.

Installing Cygwin

The first requirement is to have Cygwin installed. Cygwin can be download from the following Web site:

You will find a a simple “Setup” program. Simply follow the instructions in the setup program to complete the install. If space is not a concern, I suggest you install the entire suite of tools. But there are certain packages which might be more relevant for this setup. These include:

  • make
  • gcc
  • openssl

Basically you want to look for and install packages necessary to compile/build binaries. If you run the “./configure” command (while installing a package from source) and it complains about missing libraries or packages you can rerun this process and add them. Then run “./configure” again.

Installing Net-SNMP

Net-SNMP is quite a safe install as well. Once you have Cygwin installed, you simply need to download the Net-SNMP source and execute a few commands from a bash shell and you will have finished.

Net-SNMP can be downloaded by following the link below:

You should download to a directory such as c:\cygwin\src\net-snmp-5.x.x. Once downloaded to that directory, open a bash shell and follow the steps below:

tar xvfz /src/net-snmp-5.x.x

cd /src/net-snmp-5.x.x
make install

If you haven’t done so already, you need to specify the following system environment variables:


Test your work:
     snmpwalk -v 2c -c public [ipAddr] system

Moving Ringtones To Internal Memory – HTC EVO 3D

I just started my dance with the “Android” a couple weeks ago on the HTC Evo 3D and it has been a learning experience from typing on the on-screen keyboard to rooting. As is the purpose of this blog I try to post my learning experiences for later reference.

Ever since I got the phone I noticed that whenever I mounted the mircoSD to a computer, the ringtones would go back to the default/stock tones. Basically what was happening is, when the memory is mounted to the computer it is not accessible to the phone therefore no tones and it reverts to the settings it came with. This can be a bit annoying so I set out to do something about it. In this quest I discovered that the internal memory (/system to be exact) is mounted as read only therefore writing to that partition (read: placing files there) is not possible. So I couldn’t simply copy files onto it even though the phone was rooted.

I want this post to be as clear as possible so the the next person needing to do this wont have to go hunting around the web for bits and pieces like I had to. In order to do that though, and remain on topic, I will have to do a second post about how to get the adb stuff working. It took me a couple weeks, on and off, to get it but the crazy part is that I had it working from day 1 and didn’t even know. So I will put that together in another post as I said before.

I have pre-edited mp3s that I use as ringtones stored in my music folder on the mircoSD and what we will need to do is copy those to the Continue reading

Putty – Save Passwords

Ever since I started working on multiple servers on a regular basis I have been looking for a solution in which PuTTY is able to store passwords for the target machine. Now I think I have what can be deemed the closest thing to that (without applying keystrings or 3rd party programs), login sessions which are seeded with the relevant passwords though batch scripts.
First create and save putty session with username@IPAddr  and whatever other details are required from with PuTTY.
Next, open Notepad++ (or your preferred text editor) and create a windows batch (*.bat) file with following lines:
     cd c:\Program Files\Putty\
     putty -load "saved session name" -pw "password"
and save it like “session name.bat”
*** On some systems,especially 64 bit OS’s, Putty may be installed in “Program Files (x86)” instead of “Program Files” so make the necessary adjustment to the lines above.

Now just by double clicking on this batch file, you will be automatically logged on to the server without prompt for password. Downside is unencrypted password on your computer. You could explore using a bat-to-exe compiler which would help to mitigate some of the risk, at least from a casual prowler. ^_^

Change or Reset Windows Password from a Ubuntu Live CD – How-To Geek

If you can’t log in even after trying your twelve passwords, or you’ve inherited a computer complete with password-protected profiles, worry not – you don’t have to do a fresh install of Windows. We’ll show you how to change or reset your Windows password from a Ubuntu Live CD.

This method works for all of the NT-based version of Windows – anything from Windows 2000 and later, basically. And yes, that includes Windows 7. Continue reading
