AIX

Hi all,

I have N number of AIX hosts, where I need to login frequently and do some routine tasks (run some scripts). I need to setup ssh public/private key, so I can auto-login via a master (wrapper) script and run each script in each server.

I am trying to setup/generate ssh keys, but am facing some problems. Here's what I have done:

- Generate ssh keys, as follow:

Code:

haroon_a@myhost1:/home/haroon_a/.ssh > ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/haroon_a/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/haroon_a/.ssh/id_rsa.
Your public key has been saved in /home/haroon_a/.ssh/id_rsa.pub.
The key fingerprint is:
a2:92:49:ed:a8:c6:18:9d:ec:64:f5:fe:70:e7:09:fe haroon_a@myhost1
haroon_a@myhost1:/home/haroon_a/.ssh > ls -ltr
total 3
-rw-r-----   1 nbkysrj  staff           232 Oct 28 07:59 id_rsa.pub
-rw-------   1 nbkysrj  staff           887 Oct 28 07:59 id_rsa
haroon_a@myhost1:/home/haroon_a/.ssh > scp id_rsa.pub haroon_a@myhost2:.ssh/authorized_keys2

- So now id_rsa.pub is copied over to my host2:/home/haroon_a/.ssh/.
- When I try to do an ssh login either from host1 to host2 or from host2 to host1, the ssh login doesn't work. It still asks me for password.

- Can someone tell me what I'm missing here?

Thanks in advance.

I got the ssh auto-login to work. But here's my other question now:

- Like I mentioned, I have N number of hosts, where I need to run some scripts on a regular basis. So, here's what I have in mind.

1. Create a script in host1 to wrap arround all other scripts in other hosts (host2, host2, host4) and execute each scripts in all other hosts. i.e. something like this:

Code:

ssh to host2
execute script1
execute script2
 
ssh to host3
execute script1
execute script2
 
ssh to host4
execute script1
execute script2

But as soon as the ssh host2, is executed--the first line--, then I am taken to host2, and I'm out of the script (which is in host1).

Am I making any sense? Please advise...

Thanks.
