From the past couple of days i was getting my hands dirty with a technology called as IPSEC, which is not at all a new technology, but yeah it was new for me to configure it in the correct manner. I have seen people in the field of System Administration doing blind troubleshooting by simply changing some configuration, to get the problem fixed somehow.
Although such a kind of approach does work most of the times, but is not at all a good way to go forward. Because you are surely going to stuck again with some issue down the line, which requires proper understanding of the technology to resolve it. I can’t even blame system administrator’s for taking such an approach, because most of the times, the configuration tasks are assigned with a deadline attached to it, which makes the duration worked on it more important, rather than the configuration you did.
