How can I loggin from VM1 to VM2 using script?
I am using script to loggin my VM2 from VM1 (Password of the VM2: fifa):
for i in {a..z}{a..z}{a..z}{a..z}
do
# $i as a password
ssh root@ipaddress
read i
echo $i
done
bit it doesn't work. It always ask me to enter the password.
How can I make it to enter password automatically?
linux shell-script

It's asking you to enter "the password" because of the read i
statement, which is clobbering your for
loop variable. I believe the ssh client tries to read from the tty; I'm not aware of a direct way to pass a password to ssh. Alternatives include sshpass and expect. See SSH login with clear text password as a parameter? and https://stackoverflow.com/questions/233217/pass-password-to-su-sudo-ssh and https://stackoverflow.com/questions/12118308/command-line-to-execute-ssh-with-password-authentication
