Rule 1 - never use passwords. Don’t even think about it. Use the public key encryption option.
In layman terms what is/are the benefits of using SSH?
I manage a couple of thousand linux servers. They all are located in the datacenter several floors below me. In order to manage any single one, I need to log in.
With SSH, I can do that from my desk, without ever having to actually go the physical server.
So this is not something that a plain user would find a real reason to use it, is that an accurate statement? Or is there a reason the average computer user would see a need for this knowledge? 8>)
However, I have posted threads aimed at some of the IT professionals among us in the past. This is one of those.
Groovy! I use Putty quite a bit, so it’s nice to have another option.
In addition to PKI encrypted communications for login sessions there is the scp command which enables you to copy entire file hierarchies from one machine to others with a single command and the use of shell meta characters.
There is also the ability to create encrypted “tunnels” for data stream end points with ssh and so much more.

One of the best things Microsoft did in Windows 10 was include the SSH client, and make the server available for installation. Finally, Windows stumbles into the 1990’s.
I used to use port forwarding a lot, mostly to get around firewalls and stuff. It was very cool. Still use SSH daily. It’s a powerful tool. I’d recommend changing that command above to generate a key to use DSA. RSA is pretty much deprecated these days.
Rsync is insanely powerful and efficient. Love, love love it. Makes my life easier when I need to replicate data from one host to another. Since it uses ssh, it's secure, and can also compress to reduce transmission times, among other things.
Thank you for this. I couldn’t figure out how to change the username when using powershell to SSH into my Cisco equipment. I just wanted to use radius auth.
Yup. Good stuff.
Merry Christmas!
(Hmmm ... any chance you could sneak a F@H client onto a few thousand of those servers? Not like they are doing anything except waiting for the next cryptocurrency hijack ... not that anyone could get past your superb security :)
SecureCRT allows you to change the background of a terminal session which is nice if you have multiple servers and you don’t want to confuse them
Ace scares the heck out of the average user with these. lol
I appreciate them very much though, I have learned quite a bit from them.
It doesn’t scare me, I was just wondering if there was ever a need for just plain old users of computers, or even someone like me who is an old mainframe person, what it might be used for if we were not PC oriented. I mean I know PC’s better than most perhaps but I was trying to figure out how I might use the knowledge. 8>)
The mainframe is back, sort of, but it's called the cloud now. You'd use ssh to connect to the cloud server's Linux command prompt, and it's also the gold standard for secure file transfers. It's not flashy software but it's stable and high quality with very few bugs. It's a must learn for cloud computing.
Thanks for the info though. 8>)
