tuff problem of the day for linux

[gavino]

30 servers with veritas backup client
task
1 add 1 line to config file
2 restart backup client
3 do for all 30 servers over ssh
4 do in a script without having to goto each server and login

 

[usenet]

1 add 1 line to config file

You don't say what type of config file. If it's a "standard" type (such
as Windows-style .ini files) you can easily do this with a parser (such
as Config::IniFiles). Otherwise you will need to manipulate the file
with basic Perl I/O commands (perldoc -f open)

2 restart backup client

perldoc -f system

3 do for all 30 servers over ssh

use Net::SSH;

4 do in a script without having to goto each server and login

Of course.

Is this really 30 standalone servers, or is this a cluster? Have you
looked at Cluster::Init?

1. Write a subroutine that does [task] to one computer
2. Put names of all machines in an array
3. loop over array and call sub for each element

To put the thread on topic, search CPAN for SSH

1. *Please* do not top post: it forced me to do more editing for
clarity, that logically and operationally and would have fit better on
your part.

2. How do the last two lines correlate to 1.-3. and the additional,
good, advice given above?
