linux - How to get information from text file using PHP and remote ssh? -


i've got problem poor performance php executing bash script remote ssh , doing grep on log. in web browser receive output after 40 seconds. executing bash script(ssh + grep on remote machine) directly on local machine taking 8 seconds. know cannot bypass came idea of :

creating php script save text file on local machine "variables" need. let's call "parameters.txt". other bash script "reader.sh" read "parameters.txt" file, of magic of remote ssh , grep, save output "output.txt". background script run every 2 seconds reader.sh

is idea?

if need use php on ssh, use http://phpseclib.sourceforge.net/. have nice ssh implementation used sometime deploy applications , configure linux servers (puppet replaced it). code cleaner , easy maintain.

another option is, if reading logs linux ( messages, apache, syslog, etc...) have options rsyslog (http://www.rsyslog.com/) centralize on server , work on locally. cheaper computers , easier deploy.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
