Base64 talk encrypted

Hi all, why most of computer engineers choose Linux as their preferred os. Friends we get lot of advantages here like we can talk encrypted

For encryption
$ echo -n hi | base64
output: aGk=
For decryption
echo -n aGk= | base64 -d
output: hi

Not only this you can also encrypt image with the following command
$ echo -n $(cat image.jpg) | base64 > inputfile
To decrypt use
$ echo -n $(cat inputfile) | base64 -d

Enjoyeee…

All news at one place, shivalink.com

All news at one place, Why did I do this. I known you guys also don’t have time to scroll through all the news papers like me, but we love to read them. We have got no other option except to skip or scroll fast. And when people talk about it we just do not know what happened at the end of the story. But Being a engineer I can not stay deprived of it. So its my call to make it easier to read and all at one place.

Currently I combined three news paper those are my favorite one. But you can tell me if you want your favorite news paper or channel.

Also I wanted to go a step furthur, I kept this news engine to send emails with 3 hours frequency. It is built with elastic search (search engine type database), python, postfix ( to send mail with queue), some php at front end. It can store billions of news. you can search and go to so deep history starting from yesterday.. 🙂 hehe as it is so new. I hope u guys will like this. Here is the link Enjoy.

Hi, the below command do really have magical effect to bring ur local port on internet,

Support you are on nat (nat like you have 192.168.1.2), and you dont have public ip, but you want to show your friend your webserver, or you want him to ssh your system remotely so you need to forward your port with router that may or may not have public ip.

But if you have a remote server with public, like i do have this server, you can use that to do this task from remote. And that is very easy you can find many tutorials on internet for reverse ssh tunnel.

here are those very  easy steps you need to perform-

  1. set “GatewayPorts yes” without quotes in sshd_config file of ssh, available at /etc/ssh/sshd_config in ubuntu os
  2. use this command “ssh -g -R 8080:localhost:80 [email protected] -p 22” without quotes and you will see server.com:8080 shows what your lcoal web server has got

Enjoy I had to do a lot of research to get this successful in my case and now found that this something like path to heaven for me. it takes all the traffic encrypted with ssh protocol hehehe.

and use ssh -f -N -R 9108:localhost:80 [email protected] -p 2222 if you dont want ssh to open everytime
