Automatically enter SSH password with script

apt-get install sshpass


sshpass -p "YOUR_PASSWORD" ssh -o StrictHostKeyChecking=no YOUR_USERNAME@SOME_SITE.COM

Custom port example:

sshpass -p "YOUR_PASSWORD" ssh -o StrictHostKeyChecking=no YOUR_USERNAME@SOME_SITE.COM:2400

Variant I


Variant II

#!/usr/bin/expect -f
spawn ssh USERNAME@SERVER "touch /home/user/ssh_example"
expect "assword:"
send "PASSWORD\r"
sshpass -p mypassword autossh -M0 -t
# usage: same arguments that you'd pass to ssh normally
echo "You're going to run (with our additions) ssh $@"

# Read password interactively and save it to the environment
read -s -p "Password to use: " SSHPASS 
export SSHPASS

# have sshpass load the password from the environment, and skip public key auth
# all other args come directly from the input
sshpass -e ssh -o PreferredAuthentications=keyboard-interactive -o PubkeyAuthentication=no "$@"

# clear the exported variable containing the password

This is how I login to my servers.

ssp <server_ip>
  • alias ssp='/home/myuser/Documents/'
  • cat /home/myuser/Documents/


sshpass -p mypassword ssh root@$1

And therefore...

ssp server_ip
# create a file that echo's out your password .. you may need to get crazy with escape chars or for extra credit put ASCII in your password...
echo "echo YerPasswordhere" > /tmp/1
chmod 777 /tmp/1

# sets some vars for ssh to play nice with something to do with GUI but here we are using it to pass creds.
export SSH_ASKPASS="/tmp/1"
setsid ssh -p 22

I managed to get it working with that:

SSH_ASKPASS="echo \"my-pass-here\""
ssh -tt remotehost -l myusername

To connect remote machine through shell scripts , use below command:

sshpass -p PASSWORD ssh -o StrictHostKeyChecking=no USERNAME@IPADDRESS
