axis cam scripting

here's some bits and pieces I used to get an axis network camera to show the currently connected users.

listconnected.script
#!/bin/sh

# save to /tmp so we don't wear the flash memory out
netstat -t -n |grep ":80.*ESTABLISHED" |tr -s " " "\t" |cut -f 5 |cut -d ":" -f 1 |xargs -n 1 nslookup |grep "Name:" |tr -s " " "\t" |cut -f 2 > /tmp/connectedtmp.txt

mv /tmp/connectedtmp.txt /tmp/connected.txt


user.list.task
# immune is required to let the task finish before utask tries to kill it
{tooty} time(h(0-23)m(0-59)s(0,20,40)) once immune % /etc/scripts/listconnected.script;


# make things accessible to the webserver
ln -s /tmp/connected.txt /etc/httpd/html/viewer/connected.txt

in the html source, make sure you work around an i.e. bug that will prevent the cache from being updated
function sndReq() {
http.open('get', '/local/viewer/connected.txt', true);

// workaround for win/ie
http.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");

http.onreadystatechange = handleResponse;
http.send(null);
}

from here just do the usual to paste the result into your dom.
