Automated logon within shell scripts
Hi All,

I have created a server health checkup for 22 diferent ips and want to run my script from a single host server -->conduct health chekup on various servers--> Capture the deviations--> Get back all the deviations to the host server where the script was initiated.

Ive checkd out ssh keygen but was not clear of the process and to my dismay i dont have the root password. Is it possible that i can generate the pass key without having root password or through any other process.

Please Help...........!!i am going beyond my deadlines
Thanxxx in advance.

Regards
G.C

You can create keys for any user. But you will have to work with those users then. In other words: If root is needed, you will have to create and exchange keys for root and if it is possible to work with another user which exists an all machines, you can exchange their keys and work with this user/key.

Also please refrain to write your subject of a thread all in upper case letters next time in case you wanted to get more attention, thanks.

There is plenty of threads in this forum about using passwordless login with ssh and also on the web.

commands not running after logon
Hi Pal,

I was able to do ssh with the help of public key fundamental , i tried it out on my script but the problem is that the script stops after logging to the server and does not run any commands .But when i exit from that server the command runs automatically after that. Have a look at the script and the output --

Code:
 
nssh# cat module.sh
sleep 1
ssh nsadm@10.49.10.7; ls -lrt

nssh# ./module.sh
Last login: Wed Oct  6 15:53:24 2010 from 10.49.10.4
nssh#
nssh# exit
exit
Connection to 10.49.10.7 closed.
