What exactly SFTP is? And how to Setup SFTP Server

SFTP (SSH File Transfer Protocol) is a secure file transfer protocol and it runs over the SSH and comes with all auth and security that ssh supports. Now-a-days FTP or FTPS is getting replaced by SSH as FTP is considered as not so secure.

The SFTP protocol runs over the SSH protocol as a scheme and it was designed by Tatou Ylonen.
Special thing about SFTP is , there are no ports exposed.

SFTP VS. FTPS

People usually wish to check SFTP vs. FTPS. FTPS is essentially the previous ftp protocol run over SSL (Secure Sockets Layer) or TLS (Transport Layer Security).

Benefits of FTP over SFTP includes,
FTPS is essentially FTP, which implies it's code mode, which might corrupt files if the mode isn't properly set and SFTP runs over SSH within the normal SSH port. Thus, no extra ports have to be compelled to be opened on the server and no extra authentication must be maintained. This simplifies configuration and reduces the probability of config errors.
FTPS wants sophisticated firewall configuration and might not work NAT. Ports 989 and 990 have to be compelled to be open. 
FTPS needs an additional server software system package to be put in and patched, whereas SFTP comes with SSH.
What's more, FTPS supports each active and passive modes , that additional complicates firewall configurations and is susceptible to issues.
FTPS can't be used as a File system. 


Here are easy steps to setup Free SFTP server

To setup the Free SFTP server you can download the Rebex Tiny SFTP server
from https://labs.rebex.net/tiny-sftp-server
And surprisingly, it is free for Commericial and Non-commercial purpose.
Once download is finished, unzip the zipped file and run the "RebexTinySftpServer.exe" file.
There would be another file named "RebexTinySftpServer.exe.config" file which is a server configuration file with below config settings available by default.
The configuration is straight-forward , key-value pair and easy to understand.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<!-- user and root dir -->
<add key="userName" value="sftpuser"/>    
<add key="userPassword" value="sftpuser"/>
<add key="userRootDir" value="data"/>

<!-- user public keys for public key authentication (optional) -->
<add key="userPublicKeyDir" value=""/>

<!-- misc config -->
<add key="showUserDetailsOnStartup" value="true"/>

<!-- security -->
<add key="rsaPrivateKeyFile" value="server-private-key-rsa.ppk"/>
<add key="rsaPrivateKeyPassword" value="my-super-secure-password"/>

<add key="dssPrivateKeyFile" value="server-private-key-dss.ppk"/>
<add key="dssPrivateKeyPassword" value="my-super-secure-password"/>

<!-- port -->
<add key="sshPort" value="22"/>

<!-- start server when application is started? -->
<add key="autoStart" value="false"/>
</appSettings>

</configuration>

As SSH works on port 22 so config also has the same.
For further security , you can create RSA and DSA keys (.ppk) and provide the password in config which was used while creating the keys.
If you are not comfortable in creating the SSH keys, you can you this awesome free tool that runs on Windows called "PuttyGen" (a utility for RSA and DSA key generation )

If you are working with any SFTP client and you are just looking for test connection with SFTP Server, you dont need to host one. Rebex has already provided a dummy sftp running server at
test.rebex.net  Use demo as username and password as password



Please Note: REBEX SFTP server store the password in clear text as you can see from the config file.
Do let me know if you have any other SFTP server that can be easily setup.

Avenger Inifinity Wars Ending as per Comics

So, like everyone else, I was also wondering what would that ending means. Please note this is Spoiler Alert! if you are reading further and you have not watched the Avengers: Inifinity Wars movie yet.



We dont know what would be the strory of  upcoming film Avengers four. But we tend to do shrewdness Marvel handled a similar events once they occurred in comics. Unlike a number of its predecessors like Avengers: Age of Ultron, This movie Avengers: Inifity Wars borrows heavily from the plot of sure Marvel comics and  not just simply settings.

So, what did and how did things happened with Thanos.
 Here’s however the story bound up on the page.

Once More, Spoiler Alert!!!!

Infinity War some of its story from a comic Inifinity and rest of the story from Infinity Gauntlet, the initial story of Thanos, the time Gems and also the huge gold glove. Infinity Gauntlet was a 6 book comic book . This comics had a story about Gems or Inifity Stones connected with Thanos and also the Gauntlet.

And unlike INFINITY WAR , INIFINITY GAUNLET keep going.
So, what happend at the end.

THANOS KILLS HALF OF  THE UNIVERSE WITH THE SNAP OF HIS FINGERS

After look time War, you may simply assume that the majority of time Gauntlet is additionally involved with Thanos making an attempt to amass the time Gems and also the Avengers making an attempt to prevent him. however the primary huge distinction between infinityWar and infinityGauntlet is that the complete finding the infinity Gems thingy is  half  done even before the story starts. In Inifinity Gauntlet story starts off exceedingly in a very spectacular way: Thanos already features a gauntlet in hand with all the GEMS and is considering his new freedom as an powerful guy like a GOD.
And at the CLIMAX, Thanos does the surprising thing: He snaps his fingers and murders the half of the universe. Yes, that what you also see in the movie. Major of the superheros (except the Avengers) dies . The literal disappearance of their darling ones is that the 1st sign most of the Avengers get that something is wrong in the least.

If you are with me, lets continue!
So, what happens next???
Well, the opposite massive distinction between time War and time Gauntlet is that Thanos’ motivations ar entirely totally different. within the comics, as you will have understood. Thanos is totally passionate about winning the center of Mistress Death. Yes, that supersing. Death is the one Thanos is behind. Kind of one sided love. She is the reason he starts collecting the Stones/ Gems. She had asked to kill half of the overpopulating Universe. In a way to impress Death he does some wild things like capturing Nebula and not letting her die. He turns Wolverine's bones to Rubber, changing Thor to glass and shattering the glass so that Death would get impressed by him.
After all his wrong doings,  the more powerful characters (yes, there are more powerful characters than Thanos in the comic world) start seeing him as a potential threat. These characters are Kronos, Epoch, Galactus etc. They had a fight and somehow he wins against all of them.
During the course of time, he decides to transform himself into an astral entity and leave his corporeal form behind, which he believes will rid himself of his final vulnerability.

Unfortunately, he forgets that his godly powers ar predicated on one thing terribly corporeal: His hand being within the time Gauntlet. Nebula, United Nations agency has been mute and apparently insensible to her surroundings when Thanos place her into a continuous state of wretchedness, seizes her probability
She yanks the gauntlet from Thanos’ abandoned body and shoves it onto her own hand, and currently she’s the God within the universe. She reforms her body into health, banishes Thanos into the depths of area and sets regarding combating her new infinite awareness of area and time.
A fight happens between Nebula and Thanos where she ask him to leave the universe as it was 24 hours before and he does that. And here we are, all of our super heroes back to life again.
