At the time of my M.Tech (Post graduation) completion, I have a big confusion how to start my career professional life. However, we have nil education on software and hardware technologies in our curriculum at colleges. Even though, after getting many suggestions from my seniors and relatives who are experienced in the software industry, I am unable to conclude about what to choose.

I have been trying to get my head around ssh tunnels lately as I need to be able to access a development web server on our private network that doesn't have an IP accessible from the internet.
It's taken me a while to understand what is going on; it can be pretty confusing.
I'd recommend the following for a good explanation of what ports are used, e.g. when your browser requests a page:

And I thought this was probably the best single page explanation of tunneling:

The best comment though was the Russian Roulette method to delete something (the original had rm -rf / of course):
[ $[ $RANDOM % 6 ] == 0 ] && rm some-file-to-delete || echo "You live"
Peter Brownell posted a note on 3 November 2008 - 1:18pm.Here is a nice little bit of bash snagging for you. You need to grab lines from a file, process each in turn, and then at the very end report whether or not there was a problem for any of them. Simple ? Not quite.
The following scripts are mangled to show how this works, so don't expect them to operate as-is.
#!/bin/bash
PROBLEM=0
cat $CONF | grep backup | grep @ |
while IFS=$TAB read var1 var2 var3 var4
do
PROBLEM=1
echo PROBLEM:$PROBLEM
done
echo PROBLEM: $PROBLEM
