Very useful and easy to understand. I had to use the passphrase instead of password to make it works, but in general, everything was the same, THANKS A LOT!
great job, perfect example very clear, concise easy to learn. well explained
Paramiko makes it really easy to connect to Linux servers and Cisco devices. I used to do this with Perl years ago but it was very frustrating. You had to tell the library the different prompts, etc. IOS and CatOS devices worked differently.
Hi Sir,
Can you please specify how may I use this inspect() function to get knowledge about object?
Request: ssh basics/fundamentals. And it's use cases
Would be great.
Sick content
How do I save command output to variables? I am not able to manipulate variables when assigning variables to output
Will this code work for connecting host with IPv6 address as well?
If not what changes might be required.
It was so helpfull for me thank u very much
thx! you video my problem with Piramiko
Great Content. Could you please help me for SFTP using paramiko only the current data-1 files from Lan to remote server. I guess exec_command will work on remote server only. What if we want to run the command on out Local i.e. LAN files? please help.
How do you keep the The shell to persist with these commands. Like your pulling the hostname, if you go ahead and navigate to a particular directory. And then in the next command You want to touch file .txt you will notice that the exec closed out and that you are not in the directory that You Navigate to do but are in the home directory again. You have to change the commands inside a single exec Is there any way around that
I did same as you said but when I replace hostname with directory command 'ls -lrt' Its giving total 0 why its happening
Hi there. Thanks for the video. One quick suggestion: Do not connect to host machines as root.
Connecting as root (or allowing root over ssh) is a gigantic security flaw. We (as in the IT community) should promote the use of connecting to a remote host as a specific user, rather than root.
Thanks again! This is really cool stuff.
Hello, how can I make an paramiko SSH connection to a SSH host, through remote desktop (RDP)?
thank you.
Hello I have a duubt if I want send more command how I can do it?
This is great
can you help me with a code that actually download a file already uploaded in a remote server?
how do you run more then 1 command on 1 host for example a switch that needs password>cli>configure>hostname its been hell searching for a solution online
Any idea how you would then connect to a mysql database in that server? I cant find anything about this
You would connect to it the same way as if you were SSH'd into another server. Should just be able to run your sqlclient command to connect
please how long and big is this code?
How to keep ssh alive for long running cmd on a remote server?
I am getting socket timeout and buffed.timeout while running long running shell command on remote host.
Timeouts would be on the serverside. Check the settings on the remote host ssh server service.
I'm not sure what I'm doing wrong.... when I try to run the snippet at 1:30, I keep getting an error.
"PermissionError: [Errno 13] Permission denied: 'C:/Users/seans/.ssh/known_hosts'
I've launched python from an elevated command prompt, but no joy.
But how you get authenticated, you haven't supply password for root anywhere, have you already copied your public key to all nodes?
thanks man
Thanks for the video. I have a question - How to change directory after SSHing the server?
cd
How to open shell using this and see what's going on
I have a problem. It seems that the fingerprint of the server I was connecting to changed, but I can't get it to work again. It gives me this error:

Hi, could you share the coding again ? Cus the link for Code Available is not available now🤕
Apologies, the website is back up now!
isnt the autoaddPolicy vulnerable for Man in the middle attacks?
If you are in a more secure environment you could add to known hosts manually
but does paramiko support ssh multiplexing ? if number of sessions are running , just like ssh natively supports , please help
hey there, as of my knowledge, it does not support SSH multiplexing... but I could be wrong
@@DevOpsJourney thanks for the reply , but do you know anything which could ease up or does have the same kind of functionality, i am working on a project which involves multiple ssh to get some of the system metrics from the os , but i cant use any of monitoring tools , i can only use ssh any help i would really appreciate thanks
Sorry but how do you tell your program where the private key is stored on ur pc?
Hey Simone. Use the below function and specify the path:
load_system_host_keys(filename='path/to/hostkeys')
I hope that helps!
@@DevOpsJourney Thanks a lot!!!!
Hi, When I run the command same you given i am getting this error "Could not chdir to home directory /home/kyndrylssh: Permission denied" , can you think is that SSH connected ??? how can we confirm that...
Try a 'hostname'. That's how I confirm
@@DevOpsJourney u mean command 'hostname'? I am getting something for that also
Can I use the paramiko to run a script in the vm that the ssh server is installed?
Yup!
@@DevOpsJourney the machine that the ssh server installed can be windows? Everything Will work fine on windows?
@@davipires2999 yes you can use paramiko to ssh into a windows box
@@DevOpsJourney thanks mate, i'll try this tomorrow in my internship!!!
How to get the known hosts file created
should be in ~/.ssh/known_hosts, or c:\users\\.ssh\known_hosts
Is possible to do a sudo to another user? , ssh with brad and then sudo to tomcat?
maybe try 'su tomcat'
@@DevOpsJourney and the password?
How to stay on server in comand-line?
use while and instead of 'hostname' enter 'input()'
what is in the "known_hosts" file ?
Server fingerprints. That prompt that comes up when you ssh into a new server asking about if you trust the finger print - when you do it's saved to the known hosts file. If you try to connect to a server with the same IP but the fingerprint has changed, ssh will warn you that something has changed
@@DevOpsJourney in what format ?
Ip, type, pkey?
