Python script to save /sys config file

[MaxMedov]

Hi guys, I need help writing a dedicated script to do those things:

# tmsh save /sys config file bigip.conf no-passphrase

# netstat -nr > netroute.txt

Both of the files need to be sent to another server directory combining the device name + current date

Can anyone help, please? Thank you!

Hi @MaxMedov, this works local for me, but you might need to flesh out a little functionality to meet your needs. I used bigrest for this sample:

from bigrest.bigip import BIGIP
from datetime import datetime

datestring = datetime.now().strftime('%Y-%m-%d')
hostname = 'ltm3.test.local'

br = BIGIP(hostname, 'admin', 'admin', request_token=True)

# Save Config
data = {'command': 'save'}
task = br.task_start("/mgmt/tm/task/sys/config", data)
print(f'Task {task.properties["_taskId"]} created at {datetime.now().strftime("%H:%M:%S")}')
br.task_wait(task)
if br.task_completed(task):
    br.task_result(task)
    print(f'Task {task.properties["_taskId"]} completed at {datetime.now().strftime("%H:%M:%S")}')
else:
    raise Exception()

# Copy config to /shared/images/
data = {'command': 'run', 'utilCmdArgs': f'-c "cp /config/bigip.conf /shared/images/{datestring}-{hostname}-bigip.conf"'}
br.command('/mgmt/tm/util/bash', data)

# Save netstat -rn data to /shared/images/
data = {'command': 'run', 'utilCmdArgs': f'-c "netstat -rn > /shared/images/{datestring}-{hostname}-netroute.txt"'}
br.command('/mgmt/tm/util/bash', data)

# Download files
br.download('/mgmt/cm/autodeploy/software-image-downloads/', f'{datestring}-{hostname}-netroute.txt')
br.download('/mgmt/cm/autodeploy/software-image-downloads/', f'{datestring}-{hostname}-bigip.conf')

# Remove files from /shared/images/
data = {'command': 'run', 'utilCmdArgs': f'/shared/images/{datestring}-{hostname}-netroute.txt'}
br.command('/mgmt/tm/util/unix-rm', data)
data = {'command': 'run', 'utilCmdArgs': f'/shared/images/{datestring}-{hostname}-bigip.conf'}
br.command('/mgmt/tm/util/unix-rm', data)

  And after running, I have both files downloaded for me in my local directory:

jrahm@mac scripts % ls -als | grep 2022-09-20
   968 -rw-r--r--    1 rahm  1437522721     495338 Sep 20 01:47 2022-09-20-ltm3.test.local-bigip.conf
     8 -rw-r--r--    1 rahm  1437522721        803 Sep 20 01:47 2022-09-20-ltm3.test.local-netroute.txt

Thank you very much! I'll try it and update 🙂

Hi @JRahm, I modified the script, and this is working well, thank you!
One question, please, how do I add "no-passphrase" to the command generation of the conf file?
Thank you again

[JRahm]

Options can be added to the URL of the method, so in the case of creating a specific file of the config, I think it's just:

/mgmt/tm/task/sys/config?options=no-passphrase

[MaxMedov]

Thank you @JRahm 
Unfortunately, it doesn't help, I received an error

[JRahm]

This worked for me in thunderclient in vscode:

POST https://ltm3.test.local/mgmt/tm/sys/config?options=file+myfile+no-passphrase

payload =  {"command": "save"}

[MaxMedov]

Should I use the name of the file as "file+myfile" ? Like:

data = {'command': 'save'}
task = br.task_start("/mgmt/tm/sys/config?options=bigip.conf+no-passphrase", data) 

[JRahm]

No, my understanding is no passphrase is attached to the scf format, but verify that. The format for you in this matter should be:

?options=file+your_scf_filename+no-passphrase

and that would put your_scf_filename in /var/local/scf 

[MaxMedov]

I've tried it, and this is not working for me (I got an error)
Also, I try:
{"command": "save","options":[{"file":"bigip.conf"},{"passphrase":"no-passphrase"}]} 
and
{"command":"save","options":[{"file":"/var/tmp/test.scf","no-passphrase":""}]}

It does not work too.

[MaxMedov]

@JRahm Ok, I've tried again a few times, and it seems like this option was working for me:

data = {"command":"save","options":[{"file":"/config/bigip.conf","no-passphrase":""}]}
task = br.task_start("/mgmt/tm/task/sys/config", data)
