I try to add three SSDs as journal disks to an existing Storage Space (with powershell commands Add-PhysicalDisk and Set-PhysicalDisk -usage journal).

However strangely this increased the size of the storage pool (get-storagepool | select size).

How can I detect whether the added disks are really used for Parity Journal and Write Back Cache? Or is it not possible to add this to an already existing storage space?

How can I make an xinetd service such that a web browser can reliably show its output?

The service always sees the HTTP GET request on its stdin, and sends its reply to stdout. xinetd handles the tcp connection.

Firefox sometimes correctly shows the output. But sometimes it claims that the server reset the connection while it was still loading the page. Sometimes it shows all output, but keeps waiting for more (and when I then press ESC, it makes a new connection to the server with an empty HTTP request).

The definition for the xinetd service is:

service test
{
    disable = no
    id              = test
    type            = UNLISTED
    port            = 8043
    wait            = no
    socket_type     = stream
    flags           = IPv4
    user            = root
    server          = /usr/local/bin/test.sh
}

The script for this simple test ignores the input, just echoes a minimal html. It causes the same problem as the real thing, eventhough there I added a command to close stdout at the end.

echo 'HTTP/1.1 200 OK'
echo 'Content-Type: text/html; charset=UTF-8'
echo ''
echo '<html>'
echo '<body style="background:#dfd">'
echo '<b>hello, world!</b><br>'
echo `date`
echo '</body>'
echo '</html>'

How is this different from what a web server would do?

Windows 7 ignores the firewall rule from Group Policy, that should restrict RemoteDesktop to certain IP addresses. It works for XP, but Win7 machines still allow Remote Desktop from everywhere.

I guess the reason is that Win7 has not one, but three firewall rules for RemoteDesktop:

  • Remote Desktop (TCP incoming)
  • Remote Desktop - RemoteFX (UDP-In)
  • Remote Desktop - RemoteFX (TCP-In)

When the GPO is applied, it adds another rule, titled just "Remote Desktop", but the other three rules remain active and still allow it.

The Server runs Windows 2008-R2, so it should know Windows 7.

How can I make this work?
