Unable to run command over SSH Paramiko - python-3.x

I am logged into a device and trying to run commands over the ssh connection. Whenever I run the command I get the prompt to enter a password I pass the password through stdin and the program gets stuck at stdout.readlines(). I think the reason for that is because paramiko is not able to pass the password for that command.
Can you help?
Below is the code that I am using
def SSH_Connection():
ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(device_ip, username=username, password=password,port=22)
print(command_to_run)
stdin, stdout, stderr = ssh.exec_command(command_to_run)
stdin.write(command_pass+'\n')
stdin.flush()
data = stdout.readlines()
ssh.close()
for line in data:
print(line)
SSH_Connection()
Output of ssh -vv username#host your_command:

The scenario is like after I run exec_command, it prompts for password. It's like when you run a sudo command OS asks you for password to run it like that as soon as I run the command I get prompted for password. My command is that I log in to a network device like a router and run a command and store the output and then check the output whether it ran successfully if not then what was the error. The code works for other commands. Wwhen I am running this command over cli it asks for password and then I enter the password and it runs. I tried using \r\n in stdin.write(command_pass+'\r\n') but it still gets stuck
Below is the shell channel code I used
def SSH_Connection_Shell:
ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(host, username=username, password=password,port=22)
channel = ssh.invoke_shell()
channel.send('\n')
channel.send(command_to_run+'\n')
channel.send(pass)
channel.send('\r\n')
channel.send('\n')
time.sleep(5)
out=channel.recv(9999)
print(out)
file = open('Output_Of_Commands.txt', 'ab')
file.write(out)
file.close()

Linux SCP across 2 VMs with PORT and IP Forwarding in sshd_config file of VM1

Aim : Do SCP across 2 VMs with PORT and IP Forwarding in sshd_config file of VM1.
There are 2 servers serverX, serverY.
I would like to transfer a file from my windows machine to remote machine(serverY). But I can't reach serverY directly, hence I am routed via serverX.
Here's how the configuration of serverX portX's /etc/ssh/sshd_config looks
Match user arunch3x
AllowStreamLocalForwarding yes
AllowAgentForwarding yes
AllowTcpForwarding yes
GatewayPorts yes
X11Forwarding yes
PasswordAuthentication yes
AllowTCPForwarding yes
ForceCommand ssh arunch3x#serverY -p portY
When I do ssh to serverX portX, I am automatically routed to serverY portY. SSH is fine.
But When I do SCP to serverX portX, its not getting completed, it goes into hang-mode.
Expectation: When I do SCP to serverX portX, it must automatically route to serverY portY as per the configurations and file must land in to serverY portY
Please refer to this SCP command that I am running from Windows machine.
scp -P portX tests.json arunch3x#serverX:/tmp/tests.json
As per the above command file tests.json must land in serverY portY directory /tmp as /tmp/tests/json
Error :
After executing above command it goes into hang mode.
scp -P 30600 tests.json arunch3x#10.74.188.44:/tmp/tests.json
scp -P 30600 tests.json arunch3x#serverY:/tmp/tests.json

SSH kex_exchange_identification: read: Connection reset by peer

Hello today i am trying to connect to a ssh host but im facing some problems, i already generated a rsa public key and tried to connect to the host but this error keeps appearing :
kex_exchange_identification: read: Connection reset by peer
I already did connect once to the host but once i restarded my machine the same problem appeared.
Sometimes when i move to the next phase where i should input the password this appears: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)

What am i missing here, could it be from my configuration?
Command use to generate keys: ssh-keygen -o -t rsa -C "fc54406#alunos.fc.ul.pt"

How to use sshpass without TTY on a Node.JS backend?

I am running the following in a script:
pubkey=$(gpg2 --verbose --export-ssh-key $EXPORT_THIS_ID)
sshpass -p$REMOTE_PASS ssh -o IdentitiesOnly=yes -o StrictHostKeyChecking=no -tt -p $REMOTE_PORT root#$REMOTE_MACHINE 'bash -s' < ./adopt-machine.sh "\"$pubkey\""
as a child process in node.js with stdout and stderr piped over http (no tty, hence the -tt option for the ssh command) and am receiving the following error:
Received disconnect from 172.18.0.4 port 2222:2: Too many authentication failures
Disconnected from 172.18.0.4 port 2222
I've read that this error is a result of the agent attempt to connect using keys one at a time which is why I would think the error is related to tty(incorrect handling of password). Help?
EDIT: I no longer require piping stdout over http but am having the same issue. It may be unrelated to tty.
Using the ssh command without -tt as follows:
result=$(sshpass -p$REMOTE_PASS ssh -vvv -o IdentitiesOnly=yes -o StrictHostKeyChecking=no -p $REMOTE_PORT root#$REMOTE_MACHINE 'bash -s' < /usr/raindrop/app/gpg/adopt-machine "\"$pubkey\"" 2>&1)
results in the following output:

Similarly to what I theorized, ssh is attempting to use non existent keys in the .ssh directory.
I have resolved my issue and it had nothing to do with my code. Using sshpass -v I got this message:
SSHPASS: detected prompt, again. Wrong password. Terminating.
Wrong password...

Unable to ssh into localhost on a to use hadoop

I am using a digitalocean droplet with ubuntu 18.04 and am accessing it through ssh from my personal machine, but when i try to ssh into localhost to run hadoop namenode I cannot ssh into the local machine as it says publickey is denied!
I used the following command to create the passwordless ssh key and am logged in as root
also I have made changes in sshd key to allow rootlogin and public key authentication
ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

debug1: Skipping ssh-dss key /root/.ssh/id_dsa - not in PubkeyAcceptedKeyTypes
The server doesn't accept DSA-type keys, so your client didn't try it.
OpenSSH 7.0 and later deprecated support for ssh-dss keys because such keys aren't considered to be secure. The simplest operation for you is to use a different key type, such as RSA.

How to setup SSH keys for buildbot user

I'm trying to setup SSH keys for Buildbot's buildbot user, so it can clone my private repo without needing a username and password.
This is how I'm testing:
sudo -u buildbot bash
export HOME=/var/lib/buildbot
cd $HOME
mkdir git
cd git
git clone git#bitbucket.org:myproject/myrepo.git
the last step fails with:
Cloning into 'myrepo'...
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Why am I getting this error? I've confirmed my SSH key is correct with:
/var/lib/buildbot/.ssh folder exists with the correct permissions
/var/lib/buildbot/.ssh/id_rsa file exists with the correct permissions
/var/lib/buildbot/.ssh/id_rsa.pub file exists with the correct permissions
the content of /var/lib/buildbot/.ssh/id_rsa.pub file has been registered in my Bitbucket account as my SSH key
If I run:
ssh-agent bash -c 'ssh-add /var/lib/buildbot/.ssh/id_rsa; git clone git#bitbucket.org:myproject/myrepo.git'
then it clones my repo perfectly. Why isn't the normal command able to access my SSH key?
Edit: The output of ssh -vvv git#bitbucket.org is:

Edit: Updating buildbot's home directory in /etc/passwd to point to /var/lib/buildbot causes more problems. Now I can't even access buildbot's home directory as buildbot:
$ sudo -u buildbot bash
$ echo $HOME
/home/ubuntu
$ export HOME=/var/lib/buildbot
$ cd $HOME
bash: cd: /var/lib/buildbot: Permission denied
Buildbot now supports specifying private SSH keys (these changes will be released as part of buildbot 1.3.0). See https://github.com/buildbot/buildbot/pull/4178 and https://github.com/buildbot/buildbot/pull/4160
Disclaimer: I'm the author of these PRs :-)
OpenSSH is not using environment variable $HOME, as you can see from the log, but uses directly the getpwnam() functions to get the real home directory of running user (/home/buildbot/).
You either have to fix it in /etc/passwd or use the ssh-agent or IdentityFile option/config value to the ssh to make ssh use this key.
