remote administration question

[watergrinder]

Could somebody please help me with this?

I was trying to connect to a remote system via ssh. When I run the script from my user account, ssh connects to remote system successfully. By doing this, I am able to execute remote commands.

As the cron is run under root, I tried running the same script as root, ssh asks for root password and does't automatically login as root. Now, this can't be done everytime and especially in my case I want my script to be automated.

Is there a solution to this problem? All I am doing is to avoid placing scripts on the other server.

Thanks in advance.

Here are my notes on this issue:

Hope this helps

To be able to run an ssh utility from one server to the next without having to enter a password

1) Run ssh-keygen -t rsa on your host server this will generate a public key for the server (just keep selecting the defaults (i.e. leave the pass phrase blank …)
Note: the ssh-keygen only has to be ran once per server then just follow step #2 for each server.
2) Run the cat .ssh/id_rsa.pub | ssh username@targethost 'cat >> .ssh/authorized_keys'
You will be prompted for a password, Enter the password

3) You should be able now log into the target sever without a password.


Issues: You cannot cut and paste the data from the id_rsa.pub file bec. It will append a new line character to the file that will screw up everything!!!!!!!
If you get a message that the host has changed …….. edit the .ssh/known_hosts on the host server and remove the entry (every entry is a long line wrapped) and rerun step #2
