Rogue DHCP Servers script timeout fixed at 10s

[milindpatel63]

Is there an existing issue for this?

• I have searched the existing open and closed issues and I checked the docs https://github.com/jokob-sk/NetAlertX/tree/main/docs

Current Behavior

The timeout for DHCPSRVS script is hardcoded at 10s which is causing my script to fail since it takes slightly bit longer.
As you can see here: https://github.com/jokob-sk/NetAlertX/blob/main/front/plugins/dhcp_servers/script.py
Line no 30
It should take the timeout value from the settings config, but it's not.

Expected Behavior

Timeout specified in the settings should be applied to the script.

Steps To Reproduce

1. Set a custom timeout in the settings like so.
   

2. Wait for script to run

3. It fails after 10s timeout like so.

Hi @milindpatel63 ,

Thanks a lot for the detailed description. This helps a lot 🙏

This should be available in the next release. It would be great if you could test this. Can you please switch to the netalertx-dev docker image (backup everything at first), in about 15 minutes (or after the last action finishes) from now.

Make sure you refresh your browser cache - and click the 🔄 refresh button in the top right corner.

Thanks in advance,
j
