Emergency UNIX and Linux Support

Hi yogor,

I can modify the script but i dont know how to ssh remotely and generate a mai lreport regarding this disk space as I am a newbie to UNIX. but plz if u have nay idea on this how to do..plz post here or PM me ASAP

Thanks

Please, stay away from using "leet" abbreviations: if you want us to write whole scripts for you, you surely can undergo the effort to write "you" instead of "u" and "please" instead of "plz", yes?

Back to your problem: you should really learn how to work with ssh in a distributed environment. First, make sure all the ssh-keys are exchanged. In the following i will call the central machine from where you want to work the "server" and the others where you want to collect data from the "clients". On the server generate a public SSH key (use "ssh-keygen") WITHOUT a password.

CAUTION: if there is already one such key issuing "ssh-keygen" will invalidate it, therefore check if there isn't already one and skip this if there is.

Then log in to one client after the other and distribute this key. Copy the contents of "~/.ssh/id_rsa.pub" on the server to "~/.ssh/authorized_keys" on the client.

Now test the connection by issuing on the server (output should look alike):

Code:

user@server $ ssh <user>@<client> date
Tue Jul  3 08:39:52 CEST 2012

This executes the "date" command on the client and directs the output of it to th server.

The content of the file ~/.ssh/authorized_keys on the client should look like this:

Code:

ssh-rsa AAAAB3NzaC1y<...some lines of unreadable codes...>/bAvQ== user@server

Now distribute the script to every one of these clients. I will assume in the following that it is stored under "/admin/scripts/ygor-script.sh" on the clients.

Prepare a file with a list of clients/users on the server, like the following (the user names could be the same or different, doesn't matter):

Code:

user@server # cat clientlist
user1@client1
user2@client2
user3@client3
....

Then issue the following command on the server:

Code:

while read creds ; do ssh $creds /admin/scripts/ygor-script.sh ; done < clientlist

And your script should be executed on all the clients.

I hope this helps.
