Automatically enter SSH password with script

First you need to install sshpass.

• Ubuntu/Debian: apt-get install sshpass
• Fedora/CentOS: yum install sshpass
• Arch: pacman -S sshpass

Example:

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

Notes:

• sshpass can also read a password from a file when the -f flag is passed.
  • Using -f prevents the password from being visible if the ps command is executed.
  • The file that the password is stored in should have secure permissions.
