simplifies and to the point. well put together and delivered. Nice.
Nice video. Instead of using the host a and host b text files, to distinguish between the two machines, you can run the hostname commands on each machine. Thanks for the great video!
Crystal-clear explanation! 👏👏
Thank you, great presentation (techniques and info)
Exactly what I was looking for! Thanks!
Your instructions are very clear. Thanks, dude. God bless you.
Glad to help
Very helpful video, many thanks!
this is so helpful , thank you for sharing!!!
Congratulations on 7k
Thank you so much 😀
Nice video and informative. I am trying to to an rsync from my VM server over to my NAS. With root, I do not get prompted for a password. with any other user, I get prompted to enter a password. I tried the same for just doing ssh. Even if I have multiple keys in the authorized_keys file. What am I missing, thanks.
Thanks! It really helps!
Hi Tony, in case of doing a script in geany how would you write a script that allows an individual person to communicate via ssh (sshpass) and execute nmap scans and geoip/whois queries?
Really hope this reaches you, but will it still prompt for a password every time its changed? If the password use isn't disabled and expires and changes will they still have to receive it and enter it again?
Tony, why didn't you need to edit the sshd_config file to uncomment and change lines to no?
It still keeps prompting me for a password.
Hi Tony, thanks for the amazing tutorial. It really helps especially for me as a beginner. I have a quick question about the password. What if you don't have the server password and I only have a private key. Can you use the private key to log in instead of the password directly? My user name and IP connect me to the server but it was asking for the password. When I tried to paste the private key it won't allow me it says invalid. Is it possible to use a private key instead without login in using your password?
If that's the case, you can access the server like this:
ssh -i your-private-key user@ip
good presentation, to the point and simple enough
Glad you think so!
How can I do that with a server local windows and virtual server Ubuntu on VMware workstation ?
Thank you! If we are connecting to different servers do we generate different public keys for each server or the same one is used over and over?
You can use the same public key for multiple servers
Thanks Tony!
You bet!
Hola Tony. I do deeply appreciate your clear explanation about this important topic, but could you please let me know how we can connect to the remote server while the firewall in on, and we are not allowed to use port 22?
you can change what port ssh used. if you are trying to run ssh without opening a port, any incoming data requires an open port however, this is true every application that accesses the internet.
very useful !! thanks !!
You're welcome!
When copying the pub key, you entered a password. Where did you get it assuming you don't know it for the remote server
May I know I share the pub key to another host to logon the server with no password for another users?
thank you Tony!
My pleasure!
Thank you. (Read until the end)
I have 2 old computers in my house + 1 raspberry pi + 1 main computer.
I use sshfs to create a network between them so I can have some sort of "mesh NAS", but it was very tedious to put the 12 keys each time I tuned on any device.
One little problem. Any pc can now connect to any other PC without password, except for PC N°4. I need to input a password for (PC1) -> (PC4), (PC2) -> (PC4) and (PC3) -> (PC4).
Any idea why?
Sorry Luis, I don't know why. I would need time on your network to determine
Suggestion if the server still let you in with password after the above settings.
In my sshd_config file there is a line `Include /etc/ssh/sshd_config.d/\*.conf`
And inside this folder there were another .conf file with one line: `PasswordAuthentication yes`
So, I had to modify the other configuration file as well.
Thank You!
Hi, I just wanna ask how did you know your root@ip's password?
Thank you my friend!
No problem
what about password-less connection from linux to windows
at 4:25 , what exactly did you copy and entered exactly?
great content
short and easy to follow thx
You're welcome!
I am getting a mkdir cannot create .ssh directory already exist error?
Thanks a lot
Thank you!
You're welcome
How can you share this key if you don't have a password, or if you do have a password there is no reason to do so
I need to do that but from a windows machine to an ubuntu machine, its been hours and I jus cannot solve it.
its still asking for my root password
I just got the host key, no username,no password,What should I do now
great man, thanks
You're welcome!
Hi there! At 2:09 you "pasted your password in and entered" but what if we do not know the password? What should we do instead?
also at 4:25 you "copied the password" but from where? I am sorry I am a beginner :"))
@@israiqbal1414 I'm sure you've figured this out by now but I'm leaving this answer if anyone else get stuck on this. In the video he already knew the password and by your question it looked like you didn't know the password for your server. Well in this case one can use private key with the following command "
ssh -i your-private-key user@ip "
Any tips on setting up passwordless SSH into a raspberry pi from windows (Visual Studio Code specifically)
If using Win 10 or above, the same steps should apply. Or are you using putty?
@@TonyTeachesTech I was using VSC on windows to connect to my pi but was having trouble with generating SSH keys. Ultimately I realized the keys were not being put into the .ssh folder, and after I moved them I was able to follow your steps with ease!
Hey I was not able to find the ssh file. Am I supposed to download OpenSSH or does it only show once I have SSH'd to a destination. A bit confused and I'm sort of a noob
Perhaps if ssh isn’t installed, then you might need to install it but this typically comes preinstalled on most systems
top of the tops
thanks man
super!
password is needed in all cases
thanks bro
I have do the same thing many times but it is still asking me for the password...
On password what did you paste, I didn't get this part actually.
Assuming you already have ssh access to a server, that's your user password
this doesn't work, i'm trying it from a macbook (not a ubuntu or freebsd machine) using term
can you try it and see if you can get it to work from a mac laptop as the host
I think it requires editing the SSHD conf file on the mac - please try and see if you can get it working without using ubuntu - there probably will be different steps needed...
The sshd config file is only relevant on the server that you are sshing into. The "d" in sshd is for daemon and is referring to the background process that waits for incomming ssh connections.
When you say that it doesn't work, what error message do you get?
I AM MAD. Nothing of this works.. on a fresh ubuntu22 VPS install.
All 20 tutorials say /show the same thing. Nothing works.
to copy the pub key to another server u still need the password...
Still asks me a password
error publickey denied
1: public ip(given)
2: azure virtual machine
any suggestion?
Try to do a reload-ssh
Thanks, you save my life and time jiahahah 🙏
Missleading title. You actually DO SSH to a server with password. Not possible to transfer your key to the server without having to first establish a password connection?
Yes I suppose you're right since you initially need the password for setup
Hi Tony, I tried this from a Mac to PC, but after I input the password (as 4:23 in this video), I got some error codes, and I still need password to ssh. Is there anything I missed?
could it be the path problem?
This is only for people who are too lazy to type the password right?
It's a more secure way to connect via SSH
HEll yeah
👁👁
I sore you enter a password
Aajj
