To keep this simple this code works:
<?php $sinfo = shell_exec('ss -t -r state established'); echo "<pre>$sinfo</pre>"; ?>
And this code code doesn’t:
<?php $sinfo = shell_exec('ss -H -t -r state established | awk '{$1=$2=""; print $0}''); echo "<pre>$sinfo</pre>"; ?>
Does anyone know how I can get the code that doesn’t work to work?
I have ran the command in a normal terminal and they execute as expected, but when ran with PHP it cause a server 500 error – this seems to require a PHP code review from someone more competent than myself.
Thanks in advance 🙂
