This seems easy but I have been asking tcl and python IRC chat all day
and no one gave an answer.
I have 100 servers which need a new backup server added to a text file,
and then the backup agent restarted.
If I have a list of the servers, all with same root password, and the
connection is ssh.
How do I connect to the server, cat the line to the config file, stop
adn start the agent, and then do same to next server in list and
iterate through the 100 servers.
What script would allow this?

Try pxssh from pexpect. Look at the sample in the page.
http://pexpect.sourceforge.net/pxssh.html
It will allow you to automate ssh interactions.

Does this require a ssh client or server?

I use authpf to open up my PF firewall for internet use. Generally I just
open up putty and make a connection to the FW ( which open the ports) and
minize it till I am done. When I close putty authpf losses the ssh session
heartbeat and will then instruct the FW to close the ports. I would love to
write a simple client to do this form me instead of using putty. Do you
think these mods would work for me on a windows platform?

Thx

list of servers L.txt
#cat L.txt
config file is /var/bkupexec/agent.cfg need to add "tell epobackup" to
bottom of file
# cat "tell epobackup" >> /var/bkupexec/agent.cfg
agent is /etc/init.d/agent.ini stop (and then start)
# /etc/init.d/agent.init stop
# /etc/init.d/agent.init start
os=redhat ent 4ES
I intend to use root password which is same for all 100 servers.
#now I'm stuck

Pexpect needs a POSIX system. However, you can use Cygwin.

Windows Python (see the pty requirement); however, it seems to work
fine using Cygwin."

thx,

Read L.txt from (not your shell as you seem to be doing) Python and
connect to each one from pxssh, and send the commands you listed. I am
afraid, you will have to readup and experiment on a smaller scale. The
sample I pointed you to is a rather simple one and you don't seem to
have even tried it.

I would sugest looking at http://pexpect.sourceforge.net/ The Expect
metalanguage was specifically designed for the kind of things you are
trying to do. I used it recently on a project to configure 25
instances of an application, remotly, half over ssh half over telnet.

Could this project help you? http://sourceforge.net/projects/distribulator/

It sounds similar to what you describe.
