SEMP script required for Enabling/Disabling VPN

fellaamazingfellaamazing Member Posts: 7

I am trying to write powershell/BASH script to enable/disable VPN. Can anyone give me a sample script (BASH or powershell)

Assume My VPN URL is this:

http://10.1.255.255:8080/SEMP/v2/config/msgVpns/v001

let's assume user name is admin. Password is ADMpwd1

    An example call I have used in the past is the following (with your URL and creds in place):

    curl -X PATCH -u admin:ADMpwd1 -H "content-type: application/json" http://10.1.255.255:8080/SEMP/v2/config/msgVpns/v001 -d '{"enabled":false}'

    Change "enabled":true to enable. You can then wrap that call in any script that you want.

    What if password has special characters?
    I am getting The underlying connection was closed.
    I even tried to URL encode the password.

    For another solace machine that had simpler password, Get command is working fine, however Patch command is giving me (400) Bad Request

    That was from powershell.

    When I did the same from BASH, I always get Failed to connect to.... ; Connection refused. Interestingly the message mentions port 80 for some reason instead of the one I specify.

    I just tested and you should be able to put single quotes around the username:password field

    -u 'admin:[email protected]#'

    Can you provide the description in the error section? Does it say Bad Request?

    I made a bash script a (long) while ago to simulate a bunch of failure conditions for testing. It's not done, but maybe it can help..?
