Get network parameters from server

Copy linkTweet thisAlerts:
Jan 10.2023

Hi,
I have a dedicated server where I run LAMP.

I want to get the server’s network parameters: ip address, subnet mask or cidr, broadcast address, packets and bytes sent and received.

I know there is the “ifconfig” command where I can specify the network interface which I want to see, and I will receive the output.

But I can’t parse the output from shell_exec to values I want.

Have I to use regular expression? And how?

Thanks

@redagrauthorJan 11.2023 — When I execute this code:

&lt;?<br/>
echo shell_exec('ifconfig eth0');<br/>
?&gt;

This is the output on ubuntu 16.04:
> eth0 Link encap:Ethernet IndirizzoHW 2c:84:fc:b7:1a:7e

indirizzo inet:192.168.6.11 Bcast:192.168.6.63 Maschera:255.255.255.192

And this is the output on ubuntu 18.04:

I noticed that the output changes on different ubuntu server version. If I update the version to 22.04, I think the output will change. But now the server where I need the network parameters is on ubuntu 16.04.

How can I do?

Thanks

@redagrauthorJan 12.2023 — Yes, I can execute different code on different ubuntu server version.

At this point, it takes two ways to pull the data, each done on the specific version.

@ginerjmJan 12.2023 — Can you recognize the ubuntu version in your script or by noting the first line's contents perhaps? Something?
Copy linkTweet thisAlerts:
@redagrauthorJan 13.2023 — Concerning this, there is no problem. I insert a string, like this:
``<i>
</i>&lt;?
$version = '16.04';
# OR
$version = '18.04';
?&gt;<i>
</i>``
And on each machine I can insert the correct $version, then we can proceed.

@ginerjmJan 13.2023 — If that makes you happy

I would think that you would like to have a version of your code that recognizes any given file and knows how to handle it without manual intervention. Or that gives you a response that tells you it doesn't know how to handle it.

Success!
