Collaboration with Elog

Elog is a great program used for collaboration in a LAN or WAN environment. Its very simple to use and easily customizable. This program is ideal for sharing notes or analyzing data and ensuring everyone else knows what is going on. There is an email function as well and the ability to export and import notes/data if desired. The program can be downloaded here: https://midas.psi.ch/elog/index.html. Below are some of the things I did for customization

Alter the look of the program, it’s a .css written in html — /usr/local/elog/themes/default/default.css

Removed the word ‘demo’ from the URL and from the page and changed it to something else — /usr/local/elog/elogd.cfg

Add/adjust the fields of the form — config option listed on the menu bar of the program

Log transcript — /usr/local/elog/logbooks

After you adjust any of these, you are going to restart the elogd service and reload apache.

Splitting up a Large VM for Easier Transmission

Here is the scenario: you have a VM that you want to transfer to another system over the Internet. The VM, in its entirety, is too big to transfer as is. So what do we do? Well, we could convert the .vmx into an .ova and then split it into a few manageable sizes for transport. Once on the distant end, we can easily put it all back together. Using the steps outlined here: https://communities.vmware.com/message/2244209, we can do this. Below are very generic steps to achieve this.

1. Convert the VM’s .vmx to ova in terminal

2. Use the ‘split’ commands to breakdown the ova into manageable sizes (I usually do mine in 550 MB (550000000 bytes)). In this case the command would be ‘split -b 550000000 your_vm.ova vm_brokedown

3. Transfer the smaller files to the destination

4. In terminal on the distant end, type cat vm_brokedown* > your_vm.ova

5. Import the ova into the Hypervisor of your choice.
