Nimbostratuspython show running-config
I am trying to get a Python script to output the running config of my F5, to show everything from authentication to pools to ntp settings. With TMSH/SSH it's so easy doing 'show running-config' and then saving that output. Is there anything similar to this that I can do with the Python F5-SDK? I am trying to generate this in a cleaner fashion than 'show running-config' does it as I use this for PCI compliance evidence. Any help would be appreciated. To muddy the waters a bit I am EXTREMELY new to F5 products.
I was able to get the running config to show with Python, please see the code below:
from f5.bigip import ManagementRoot mgmt = ManagementRoot("your_f5_ip", 'username', 'password') x = mgmt.tm.util.bash.exec_cmd('run', utilCmdArgs='-c "tmsh show running-config"') print(x.commandResult)
is currently not supported in the iControl REST framework. You can call thetmsh show running-config
endpoint as a workaround. A curl example is shown below:/mgmt/tm/util/bashcurl -sku : https:///mgmt/tm/util/bash -X POST \ -d '{"command":"run", "utilCmdArgs":"-c \"tmsh show running-config\""}'The output from the tmsh command is shown in the
field. All the lines are concatenated by translating LF (0x0A) to literal \n. In bash, you may pipe the output to something like this:commandResult| python -m json.tool | grep commandResult | sed 's/\\n/\n/g'Of course, you can do better using Python.

omkar1hey mike did you ever get a chance to modify data in a cleaner fashion.
I am trying to do the same thing as you are

It worked well for me. What do you mean to "modify the data".
Karol_Biernack5It aint pretty , but it should do the trick, one possible improvment would be implementing list with all commands you need and for loop
import paramiko,time device_1 = '172.16.1.53' devices = [device_1] username = 'cisco' password = 'cisco' ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) for device in devices: ssh.connect(device, username=username, password=password,allow_agent=False,look_for_keys=False) file_template = 'output.{}.txt'.format(device) with open(file_template, 'wb') as file_handler: channel = ssh.invoke_shell() channel.send('term length 0\n') time.sleep(2) out = channel.recv(9999) channel.send('show running-config\n') time.sleep(15) out = channel.recv(9999) file_handler.write(out) file_handler.close() ssh.close()- Malware_Mike_37
I was curious how I could run commands without the F5-sdk, thanks for the share, Ill be using paramiko at some point in the future!

If you want to do bunch of "show's" on your F5 devices this will do the trick,sadly new library netmiko (from Kirk Byers) doesnt provide much methods for F5 , but if you would like to do some configuration based on templates i strongly suggest using terraform from Hashicorp (LTM) https://www.hashicorp.com/blog/new-terraform-providers-f5-nutanix-tencent-helm.

Very good that F5 is now included in Terraform, but it still lacks support for TLS/SSL certificate handling, an essential part of a load balancer :-(Do you know of any plans to support in Terraform the new AS3 declarative method by F5?
