Showing active gateway if more than one

[oleua]

Hi! I have more than one gateway, so the dashboard shows all of them. I suggest to show the active one separately.
My suggestion to update Linux.php file in case of using Linux:

        public function getNetworkInfo(): array {
                $result = [
                        'gateway' => '',
                        'current_gateway' => '',
                        'hostname' => \gethostname(),
                ];

                if (function_exists('shell_exec')) {
                        $result['gateway'] = shell_exec('ip route | awk \'/default/ { print $3 }\'');
                        $result['current_gateway'] = shell_exec('ip route | awk \'/default/\' | awk \'/metric 1/\' | awk \'{ print $3 }\'');
                }

                return $result;
        }

And in settings-admin.php template file:

                        <div class="col col-12">
                                <?php p($l->t('Hostname:')); ?>
                                <span class="info"><?php p($_['networkinfo']['hostname']); ?></span>
                        </div>
                        <div class="col col-12">
                                <?php p($l->t('Gateways:')); ?>
                                <span class="info"><?php p($_['networkinfo']['gateway']); ?></span>
                        </div>

                        <div class="col col-12">
                                <?php p($l->t('Active gateway:')); ?>
                                <span class="info"><?php p($_['networkinfo']['current_gateway']); ?></span>
                        </div>

Of course, to update functions everywhere.

Hi, and thanks for reaching out.

Removing the gateway is actually on my list of things to do because it's not that important and requires shell_exec to obtain the value. A while back, I shared a proof of concept at #169 (comment) on how we could obtain that value without using shell_exec, but there was never a response. Therefore, I don't consider the need for that value to be very high.

Given this, I also don't see the need to extend it to handle multiple default gateways. I believe the list is sorted by metric anyway, and the first item shown in serverinfo is already the "active gateway," correct?

That is a nice idea, as I am also supporting as much as possible abstracting from specific distro and installed apps.

True, but for me it was not obvious :) The server has lte backup channel, so in case of troubles with the main one it switches to the second one, and back again. So, I'd like to see the active one. Apart of this I was thinking to add dns values on active gateway, however it needs shell_exec again...
