Shell Programming and Scripting

Hi All,

I have 100 servers , my task is to copy data to all 100 servers for that i wrote a script,but it is asking password for each and every server,can we do it without asking password for every time,like get from a file

ex script
--------
#!/bin/bash
for i in `cat ips`
do
scp file root@$i:/

echo "copied files suffcssfully to "$i

done.

cat >ips

10.239.49.21
xx.xx.xxx.xxxx



Thanks in Advance.

Jagan,

search google or this forum for "password less ssh"

Thanks,

My task is i don't want to enter password it should take it one by one to the corresponding ips from a file, if we store all passwords in a file.

Actually i do it manually but every time i entered password this is some what time consuming ,Can anybody help me..

Thanks
Jagan.

Google "passwordless ssh".

Putting a password in a file is a serious security blunder.

Putting all passwords in a file is faintly hilarious.

There are much, much better ways to do it if you'll just give them a try.

Hi Corona,

Thanks for suggestion. I did all servers make it as password less login but i have small problem for each and evey time i need to enter "yes" to copy data, Can you please suggest me

ex :
----
RSA key fingerprint is 46:4e:c2:43:ba:ee:12:0e:9a:ff:9c:24:e1:e3:86:e3.
Are you sure you want to continue connecting (yes/no)? yes

Is there any way without enter "yes" always..

Please help me

Code:

 
-o StrictHostKeyChecking=no
