Automatically passing ssh password in scripts especially to ESX where passwordless ssh is hard

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 from :   This works better for me though for sshfs: echo $mypassword | sshfs -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no user@host mountpoint -o workaround=rename…

Recording a session for a user when he / she logs in ssh
