ssh is designed to prevent you automatically giving a rawtext password because this is insecure. It has better mechanisms for using the key noninteractively. ssh-agent can hold the key for you to reuse repeatedly once you enter the password just once:
Code:
$ ssh-agent > ~/.ssh-agent
$ . ~/.ssh-agent
$ ssh-add
Enter passphrase for key '/home/gaia_user/.ssh/id_rsa': 
# After this point, you should be able to run ssh noninteractively, ssh-agent will store the key until it's killed.

Hi,
I need to pass to ssh-agent the passphrase at the beginning of the script.
I found something about about this issue and I wrote this:

spawn ssh $USER_SERVER@$HOST_WHITEBOARD
expect "*ssh/id_rsa*"
send -- "${PASSW_SERVER}\r"
send -- "\r"


I have problem with command spawn and send.
If I launch them I receive these errors:

Quote:
[gaia_user@server01 RMS_GSRWorkflow]$ spawn
bash: spawn: command not found
[gaia_user@server01 RMS_GSRWorkflow]$ /usr/local/spawn
bash: /usr/local/spawn: No such file or directory

bash: send: command not found
[gaia_user@server01 RMS_GSRWorkflow]$ /usr/bin/send
bash: /usr/bin/send: No such file or directory

If I search these packets with yum I receive these information:

So I'm blocked at this point.

How can I pass the passphrase only one time at the beginning?
Thanks, bye bye.

Java
I thought Spawn was part of expect and does not require any other external binary.

Anyways..... Could you try this and update the results:

Create two files and chmod 755 them:

File: GetData.sh
Code:
#!/bin/bash
./Query.exp  > /infoman/test/juniper/file.txt

File: Query.exp
Code:
#!/usr/bin/expect -f
spawn $env(SHELL)
send -- "/usr/bin/ssh user@IP"
expect password:
send "Password\r"
send "get system | include mac|Int|Ser|Software"
expect eof

in 2nd file I have put expect -f not -- and also I spawn SHELL not ssh directly ... and most of it is same.

Hi,
I tried to execute the script you wrote but I receive this error message:
Quote:
[gaia_user@server01 RMS_GSRWorkflow]$ ./GetData.sh
./GetData.sh: line 2: Query.exp: command not found
What do I forget or what is the mistake I make?
Thanks, bye bye.

Apologies the backtick ` in first script should not be there !! [updated script in my previous post above]

... also try executing 2nd script basically it (2nd script) will throw the output ..

Please make sure expect is correct path ... as mentioned in script

I tried again but I receive error.
I removed the ` and I receive:

Quote:
[gaia_user@server02 ~]$ ./GetData.sh
": no such file or directory
What is this error?
Thanks again, bye bye.

Have you chmod 755 the files

$chmod 755 GetData.sh
and also
$chmod 755 Query.exp

try running ./Query.exp
