Change the network settings of the logic machine by script

[Carlos Padilla]

Good friends, is it possible to change the network settings of the logic machine? . The idea is that you can change the network credentials of the LM from the visualization with the help of a script. Thank you

Which network settings do you want to change? What is the use case for this?

[Carlos Padilla]

The network configurations that I want to change by script are the IP, the network mask, the gateway and the DNS. The above is because a client from time to time for safety issues in their network equipment, is changing the network settings of these and the idea is that the client can change them from a page of the display and thus prevent access to the mode administrator (system config and logic machine) in such a way that it can not modify by mistake fundamental aspects in the operation of the LM, script, ect. The idea is that if you can, be by means of a script since a design of icons and colors was made to the visualization and that new page has to have the same aesthetics. Thank you and I am attentive to your comments.

You can change network configuration like this, reboot is required afterwards:

Code:

require('uci')
uci.set('network', 'lan', 'ipaddr', '192.168.1.2')
uci.commmit('network')

Other possible configuration values apart from ipaddr are gateway, dns, netmask.

This is still both a security and reliability issue. If client configures any parameters incorrectly then the device won't be reachable at all. I don't see how changing IP addresses improves security.

Would it be possible to change BACnet settings as well, BACnet ID, port etc?

[admin]

For BACnet ID use this:

Code:

require('uci')
uci.set('bacnet', 'server', 'devid', 123)
uci.commmit('bacnet')

You can download the system config backup and check what other fields are present in the config files.

Great! Thanks.
