Python Parallel SSH get only command output

Question

I'm new to Python and i'm looking to run multiple parallel ssh connections and commands to the devices. I'm using pssh link for it. Issue is the device returns some big header after the connection like 20-30 lines. When i use the below code what is printed out is the result of the command but at the top there's also the big header that is printed after the login.

hosts = ['XX.XXX.XX.XXX']

client = ParallelSSHClient(hosts, user='XXXX', password='XXXXX')
output = client.run_command('command')

for host in output:
    for line in output[host]['stdout']:
        print line

Anyway i can get JUST the command output ?

Answer 1

Not sure I understand what you mean. I'm using pssh as well, and seems like I'm using the same method as you are in order to print my command's output, see below:

client = pssh.ParallelSSHClient(nodes, pool_size=args.batch, timeout=10, num_retries=1)
output = client.run_command(command, sudo=True)
    for node in output:
        for line in output[node]['stdout']:
            print '[{0}]  {1}'.format(node, line)

Could you elaborate a bit more? Maybe provide an example of a command you run and the output you get?

checkout pssh.
This tool uses multi-threads and performs quickly.
