I am trying to port all the powershell based QA automation
scripts to python. I was using plink to send ssh commands to the targets, mainly
cisco switches and store output to a text file and then generate an html report
with selected output from the text file. It seems paramiko is the favorite of
all when it comes to ssh via python.
Here I want to share a post on how easy it is achieve this.
First let us define the variables which we will be using.
target = '10.1.1.1 #cisco nexus 9000
username = 'admin' #username
password = ‘@dmin' #password
command =
'show run' #command to run
and the rest of the stuff which does the actual work is
import paramiko #import paramiko
module
ssh = paramiko.SSHClient() #create
an ssh client
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
#auto accept ssh key
ssh.connect(target, port=22,
username=username, password=password) #connect to the target
stdin, stdout, stderr =
ssh.exec_command(command) #execute the command
output = stdout.readlines() #get the
output
outstore = '\n'.join(output) #format
the output to print each line in a new line
print output
#print output
I have added
the description against each line for you to understand what and how does it
work.
If you have
many commands for which you want the output then just go ahead and create an array
and run a loop against that array. If you want the output to be written to a
text file then modify the last line accordingly. I hope this is enough to get
you started.
