PHP Shell Scripts: bringing up and down Interfaces and checking whether enabled

[andipandi]

Hello!

I am trying to both find out if an interface is enabled right now, as well as to change the state. It seems to be half working.

print_r($config['interfaces']['wan']['enable']);

$config['interfaces']['wan']['enable'] = false;
$config['interfaces']['wan']['disabled'] = true;
write_config();
interfaces_sync_setup();
exec;

// interfaces_bring_up('wan');
interface_bring_down('wan');
interface_bring_down('pppoe0');
interface_reconfigure('wan');
print_r(Interface_isppp_type('wan'));
interface_configure('wan');
interface_configure('pppoe0');
//interfaces_setup();
print_r(get_interface_list());
exec;

I have 2 main issues:

1. getting enabled state seems to be unreliable, especially, sometimes this value is not set

2. changes are not applied. I have to use

system_reboot_sync();

which works but which I really would like to avoid, since it takes a long time and does not match the "apply changes" web UI option, which seems a little more leightweight.

Thanks!

Best solution I had for this so far was to parse ifconfig….  but might I suggest that you ask this question in the development forum.... much more likely to be seen by someone who knows their way around pfSense internals/code.

If you get a good answer please mark your thread solved....

Thanks for 1) I thought the same (from what I have seen so far, and not having found a way to access CARP state otherwise).

For 2) I am still searching.

Also, I asked mod to move.. only saw "how do I compile x" messages in dev forum, that is why I went to general.

So.. i copy/pasted the code from the UI interfaces.php (the "apply" POST). Also, I had to persist the .interfaces.apply for each configuration (enabled and disabled).
Gateway assignment and defaults still were a huge issue.. so I am happy it is running for now.

I guess this will break with some update in the future (would be nicer to have a clear cut between UI and some fixed logic with a documented API), so I will be a little more reluctant to update that box.

So.. what I have now is a PPPoE-CARP (well, the CARP is only on the LAN, but the WAN uses PPPoE depending on who is CARP master, so they also share the same WAN IP), I also just added a VLAN interface to have HA of the relevant parts (for me VPN, IPSEC and OpenVPN) sync from Master to Backup via HA.

When the MASTER beocmes unavailable, it takes a little over 1 minute till the BACKUP is dialed in, but still, I hope this will prevent me from remotely locking myself out in the future, plus it should make system updates a lot better (internet connection only interrupted for 1 minute, available afterwards again with same features).

According to my tests, the valid syntax

$config['interfaces']['opt1']['enable'] = "";
or
unset($config['interfaces']['opt1']['enable']);

interface_reconfigure('opt1');
write_config('enable/disable opt1 interface');
exec

Real-time enable/disable interface
No need for system_reboot_sync();
