Does nginx use the direct client's IP for ip_hash, or does it also observe X-forwarded-for HTTP header to use as the IP address to ip_hash?

For example, in a situation where some clients using a shared proxy server access an nginx load-balancer w/ ip_hash, would all of those clients hash to the same node?

Or would nginx use the X-forwarded-for header to hash them to different nodes?

I have an nginx web server sitting in front of a Jetty Java app server running a web application.

I'd like to configure nginx to return a HTTP 503 if the proxied Jetty server is down.

This way when I bring the app server down for maintenance, of if it happens to crash, a 503 is returned to any clients letting them know the site is temporarily unavailable.

However, with the basic configuration, Nginx returns a HTTP 502 Bad Gateway when it can't connect to the proxy_pass location.

Is it possible to configure nginx to report a 503 instead?

I have a CentOS Linode instance that I'm running as a LAMP stack. I'm also using Google Apps for email. I have my MX records pointing at google's servers and everything is working in terms of relaying my emails just fine.

However, sendmail on the box is not working correctly, which means that emails from PHP (wordpress) are not being delivered.

Looking at the local mail I can see these messages repeated in the logs - 

   ----- Transcript of session follows -----
<my email addr>... Deferred: Connection refused by aspmx.l.google.com.

I have no experience configuring sendmail - can anyone tell me where to start in working out this issue? I've done a lot of googling but to no avail.

We work in a locked down privilege environment, to the point that we are not able to see the the list of processes and CPU usage of the windows services running on one of our development servers through the Task Manager.

Is there another (command line for instance) tool that we could use on Windows Server to get a list of all processes running on the machine + CPU usage, even with the Task Manager's disabled "Show processes from all users" checkbox locked down?
