Simple webserver test script (bash)
 

ok, I'm trying to do something simple and overcomplicating myself again...

I want to test an old pc of mine as a webserver. I'd like to:

open 5 concurrent connections to www.whatever.com

wait 5 seconds

close connections

loop


I've tried a few runs at it using w3m as my command line browser (which is probably the wrong thing to do) and had no success with the closing of the browser using $TIMEOUT or kill $!

any help would be greatly appreciated!

thanks in advance,

adam

Well, 5 seconds are maybe a little to fast to establish all those connections, and your server could be limited to 4 sessions from the same computer.

This line works for me with the lynx Textbrowser:
lynx -accept_all_cookies -dump http://www.whatever.com > dumpfile.txt
Now you can parse the file for "Error", "404" etc.

There a a few more parameters for lynx, like source, auth.

Very intresting could it be, to measure the time it takes to get the page.

Hi. I don't know if it's what you're looking for, but the following will kill all instances of a program - you could launch 5 instances of (for example # lynx www.whatever.com), wait 5 seconds, and kill them all with:

# ps -A | grep lynx | awk '{print $1}' | xargs kill -9

5 seconds later.

e.g.
#!/bin/bash
while true; do
lynx www.whatever.com &
lynx www.whatever.com &
lynx www.whatever.com &
lynx www.whatever.com &
lynx www.whatever.com &
sleep 5
ps -A | grep lynx | awk '{print $1}' | xargs kill -9
done

It'll mess up your console while it's running, but it works.

Or you could use 'wget' to request whatever resources you want - wget returns to the console after it's finished downloading, so you wouldn't have to kill the processes.

hmm, interesting indeed. it looks like some of the things i've tried with slight variations..

thanks very mutch!
