ssh accept "yes" in automation script possible ?
With the help of ssh i am executing the script...
Before executing the ssh command, at very first time i need to do ssh manually and typing "yes" to accept RSA key fingerprint...Can we do it through automation by passing yes as an argument...
$
The authenticity of host 'hostname (xx.xx.xx.xx)' can't be established.
RSA key fingerprint is 83:71:28:7c:55:38:28:4e:9e:51:32:57:19:9e:d2:d9.
Are you sure you want to continue connecting (yes/no)? yes

Yes you can.
Try launching it from expect, or using an expect module for your favorite scripting language. I do this all the time in python, and in regular tcl/expect.#!/usr/bin/python import pexpect, sys, time, re SSH_NEWKEY = 'Are you sure you want to continue connecting' ssh = pexpect.spawn('ssh user-name@%s'%(host)) retval = ssh.expect([SSH_NEWKEY, '[Pp]assword:', pexpect.EOF, pexpect.TIMEOUT] , timeout = TIMEOUT) time.sleep(1) if retval == 0: ssh.sendline ('yes') i = ssh.expect(['[Pp]assword: ', pexpect.EOF, pexpect.TIMEOUT], timeout = TIMEOUT) time.sleep(1) if i > 0: .....
OR#!/usr/bin/expect ...... proc myconnect { ip pass enable } { if { $ip != "" } { spawn ssh admin@$ip expect_before { "Connection closed by $ip" { catch { close -i $spawn_id } return 0 } } expect { # anticipate connection issues along the way and not get hung up timeout { return 0 } "Connection refused" { return 0 } "Are you sure you want to continue connecting" { send "yes\r" exp_continue } "Do you want to change the host key on disk" { send "yes\r" exp_continue } .......
