I am running a WHS 2011 and try to proxy an internal webserver (subsonic) over IIS7. The goal is:

https://external_host/subsonic -> http://internal_host:4040

What I've done so far:

  • Created a Virtual Directory "subsonic" in the Default Web Site
  • List item

Created the Rewrite Rules

Whenever I call the URL https://external_host/subsonic I'll get a 404 while trying to access https://external_host/login.view. login.view is in fact the login page of the internal web server.

Here's the config on the Virtual Directory "subsonic":

    <rewrite>
        <rules>
            <rule name="ReverseProxyInboundRule1" stopProcessing="true">
                <match url="(.*)" />
                <action type="Rewrite" url="http://homeserver:4040/{R:1}" />
            </rule>
        </rules>
        <outboundRules>
            <rule name="ReverseProxyOutboundRule1" preCondition="ResponseIsHtml1">
                <match filterByTags="A, Form, Img" pattern="^http(s)?://homeserver:4040/(.*)" />
                <action type="Rewrite" value="http{R:1}://www.external.com/{R:2}" />
            </rule>
        </outboundRules>
    </rewrite>

Is it possible to run a Reverse Proxy on a Virtual Directory at all?

I have just installed Monitorix on ArchLinux using the tutorial here: wiki.archlinux.org/index.php/Monitorix

I am using the Lighttpd web server.

It is working fine and the graphs are being generated, but instead of text on the graphs its replaced by 'boxes' like the language is missing or something. See picture here:

Picture of bad graphs: http://cl.ly/99929108eeabf3ed72da/

My /etc/monitorix.conf file is using "en" as the laungage:

# General
our $TITLE = "Hodge Inc.";              # your company name
our $HOSTNAME = "hodge-fs";             # hostname of this server
our $OSTYPE = "Linux-Arch";             # choose your OS type (see below)
our $SAMBAVER = "3";                    # Samba version (2 or 3)
our $MULTIHOST = "N";                   # Enable multihost feature
our $MULTIHOST_FOOTER = "N";            # (multihost) display URL in image
our $MULTIHOST_IMGPERLINE = "2";        # (multihost) # of images per line
our $REPORT_LANG = "en";                # Report language

Any ideas?

Ever since installing Ubuntu 10.04 I've had issues getting things to auto-start.

I have installed webmin and VirtualBox but every time I reboot I have to manually run:

sudo /etc/init.d/webmin start
sudo /etc/init.d/vboxdrv start

I have run:

sudo update-rc.d -f webmin remove

and then

hodge@hodge-fs:~$ sudo update-rc.d webmin defaults
update-rc.d: warning: webmin start runlevel arguments (2 3 4 5) do not match LSB Default-Start values (2 3 5)
 Adding system startup for /etc/init.d/webmin ...
   /etc/rc0.d/K20webmin -> ../init.d/webmin
   /etc/rc1.d/K20webmin -> ../init.d/webmin
   /etc/rc6.d/K20webmin -> ../init.d/webmin
   /etc/rc2.d/S20webmin -> ../init.d/webmin

   /etc/rc4.d/S20webmin -> ../init.d/webmin
   /etc/rc5.d/S20webmin -> ../init.d/webmin

But it they still refuse to start on boot. Any ideas?

after a power failure my RAID array refuses to start. When I boot I have to 

sudo mdadm --assemble --force /dev/md0 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sdg1

to get mdadm to notice the array.

Here are the details (after I force assemble).

sudo mdadm --misc --detail /dev/md0:

I am trying to uninstall Exchange 2007 on a secodary server which has been decommissioned for quite a while (cleaning up after an old Network Admin). The only roll the server had was "Mailbox Role" (the primary server also has this). I have tried uninstalling using Programs and Features GUI tool but that hung on Mailbox Role Checks.

I then tried uninstalling Exchange by running Setup.com /mode:uninstall. It has been stuck on 1% of "Mailbox Role Checks" for over 3 hours now.

Is there any other options I have for uninstalling Exchange 2007 so the old server can be removed from the Exchange Management console?
