GIT Commands Using Java APIs

March 26th, 2013 9 comments

In previous posts, I’ve covered an Java API called JGIT for working with GIT. Besides the low level APIs, JGIT also supports high level command line like interfaces. If you know how to use the GIT command line, you can use the APIs. Note that it’s different from calling GIT commands or any other commands from Java code.

Here is a sample code I wrote to try out the APIs. Give it a try and you will like these high level APIs.

How to Use the Missing Virtual Network Editor in VMware Player

March 13th, 2013 16 comments

For most people who use the VMware Player, DHCP is good enough for the NAT network. That means the IP addresses of your virtual machines may change after each powering on.

What if you want to have static IP addresses? It’s pretty easy as long as it’s in the same subnet. For example, if the VMnet8 has IP address of, your virtual machines should be configured in the same network say 192.168.47.x, where X can be any value from 3 to 254 (2 reserved for gateway, 255 broadcast by default).

Configure Static IP Address on Linux VM in VMware Player

March 12th, 2013 19 comments

If you run VMware Player, you would have 3 networking options for virtual machines running there: Bridged, NAT, Host-Only. In the latest 5.0.1, I also found a new one: LAN Segment. This blog has a nice explanation on these three settings if you want to get more details.

In most of cases, I use NAT for networking because the virtual machine can have Internet access which allows me to install additional software as needed. By default, VMware Player uses DHCP to dynamically assign IP address while using NAT. So you cannot guarantee to get same IP address after each rebooting.

MiniNet: A Starting Point to Software Defined Network

While reading Michael White’s newsletter (a weekly digest regarding VMware technology that I find very useful and read regularly) a while back, I came to know a small emulator tool for SDN called MiniNet ( I got a little time to read and play with it over the weekend and though it’s worthwhile to share my experience here.

Generating Checksum on Windows

March 4th, 2013 2 comments

I got an interesting request from one of the enterprises which uses vijava in their product. Although there are downloads for binary and source packages on the sourceforge Web site, they still would like me to create the checksum as I am the trustable source for that. As I was told, the checksum is required by their build team. I don’t know how is exactly used, but I decided to help out anyway.

VMware Partner Exchange 2013: Observations and Thoughts

March 3rd, 2013 5 comments

I went to the VMware Partner Exchange in Las Vegas last week. It’s always nice to see old friends and colleagues in the conference that I’ve been attending consecutively since I first joined VMware in 2007.

I spent quite some of my time in the hands on labs (codenamed Project NEE), which turned out to be a great experience. I took 7 labs covering the Nexus 1000V with VXLAN, vCenter Orchestrator(vCO), DynamicOps (now has a fancier name called vCloud Automation Center), etc. With the bundling and deep integration of the vCO into vCenter Web Client, I think the prime time for vCO as the automation tool for vSphere has finally come.
