Linux Batch Build trust relationship, implementation of SSH without password login script

Role:

Copy the SSH public key of the current machine to another machine to enable SSH login to other machines from the current machine without password.

How to use:

1) Write the IP address you want to add to a file, such as host

2) Save the script as sh file, such as Install_ssh.sh set executable permissions

3) rewrite the password settings in the script, currently only support a fixed number of passwords.

4) Execute the command

SH install_ssh.sh

Code:

#!/bin/sh


auto_ssh_copy_id () {
Local host=$1
Local passwd=$2
Expect-c "Set timeout-1;
Spawn Ssh-copy-id [email protected] $HOST
Expect {
*publickey* {exit 1;}
* (yes/no) * {send yes\r; exp_continue;}
*password* {send \ "$PASSWD \r\"; exp_continue;}
* * {send \ "$PASSWD \r\"; exp_continue;}
}";
}


#eof {exit 0;}
passwd1= ' [email protected] '
passwd2= ' [email protected] '
passwd3= ' [email protected] '
passwd4= ' 123456 '
passwd5= ' ASDASD '
passwd6= ' 12345 '
while read line; Do
echo "$line" >&2
Issucceed= ' FALSE '
For PW in $passwd 1 $passwd 2 $passwd 3 $passwd 4 $passwd 5 $passwd 6
Do
If auto_ssh_copy_id "$line" $PW
Then
Issucceed= ' TRUE '
Break
Fi
Done


if [$isSucceed! = ' TRUE ']; Then
Echo ' NOTSUCC ' $line
Fi
Done
