Thanks,
Your code works as expected! Can you tell me what your code is doing
different than mine?

os.system is not the best way to handle this you may want to look into
the subprocess module
however:
import os
username = 'charlie'
private_key = '/path/to/key'
ssh = '/usr/bin/ssh'
command = 'hostname && df -h && exit'
servers = ['172.16.1.1', '172.16.12.2', '172.16.1.3']
for host in servers:
os.system("ssh %...@%s -i %s %s" %(username, host, private_key,
command)

Hi,
I'm very very green when it comes to python. I know bash better than
python, so I figured a good way to learn things was covert my bash
stuff to python. So here goes...
Here's a quick example of the code I have that is broken.
import os
username = 'charlie'
private_key = '/path/to/key'
ssh = '/usr/bin/ssh'
command = 'hostname && df -h && exit'
servers = ['172.16.1.1', '172.16.12.2', '172.16.1.3']
for host in servers:
print(os.system(ssh -l username -i private_key host command))
What I'm trying to do is is, is use ssh with a private key. That way
I can quickly run some remote commands on a few hundred servers in a
quick way to do stuff (disk usage, top, etc).
When I run this, I get errors like this for every host in my list.
Warning: Identity file private_key not accessible: No such file or
directory.
ssh: Could not resolve hostname i: nodename nor servname provided,
or not known
65280
My first thoughts are, it's not passing my variables to the function
the way I'd expect.
So my questions are...
1.) Is it nessacary to put my IP's in quotes?
2.) When I call a variable in a function (like os.system() or
print()) I don't use $'s right?
3.) Am I putting variables in my functions properly? Can I put
variables like this in there?
Thanks for any help.
Charlie
