Running BASH commands via REST API

[Tim_Harber]

I am trying to run bash commands via the REST API but am getting an error. When trying to use the following syntax I am getting a 403 running with Admin authentication...

GET: https://F5LTM/mgmt/tm/util/bash

Output:

{"code":403,"message":"Operation is not allowed on component /util/bash.","errorStack":[]}

Does anyone know if this is possible, or have any syntax examples of how to run bash commands? I assume you need to submit a post request, but I am not sure how to structure the syntax in the body of the request and cannot find any examples.

Hi Tim,

Take a look to the example below to see the required format of the request...

curl -vsk -u 'admin:admin' -H "Content-Type: application/json" -X POST https://YOURDEVICE/mgmt/tm/util/bash -d "{\"command\":\"run\",\"utilCmdArgs\":\"-c 'echo "Hello World!"'\"}"

Cheers, Kai

I also needed this as I was getting the same error , when trying to start bash scripts with REST-API. The other idea I was going to try is to use tmsh script (https://clouddocs.f5.com/api/tmsh/script__run.html ) as the example https://community.f5.com/t5/codeshare/creating-a-tmsh-script-with-icontrol-rest-and-using-it-to/ta-p... and use the "tmsh::run util bash -c " in the script then trigger  with API endpoint "mgmt/tm/cli/script" but that seemed too complex for a simple bash command.

Hi Tim,

try these Postman settings...

Request Settings:

Method: POST
URL: https://YOURBOX/mgmt/tm/util/bash
Authorization: BasicAuth = YourCredentials
Headers: Content-Type = application/json
Body: {"command":"run","utilCmdArgs":"-c 'echo \"Hello World\"'"}

Note: You can also set the Content-Type on Postmans "Body" pane. Click on the down arrow to see the predifined JSON setting...

Expected Result:

{
  "kind": "tm:util:bash:runstate",
  "command": "run",
  "utilCmdArgs": "-c 'echo \"Hello World\"'",
  "commandResult": "Hello World\n"
}

Cheers, Kai
