Recently after upgrading to Ubuntu 8.04/Firefox 3, all of my CSS fonts have been HUGE! I didn’t have the opportunity to look for a solution, so I have been using Opera as my primary browser. After finally getting a little time to dig, I found a quick fix using the following steps.

1. Type “about:config” in the address bar of Firefox
2. Accept the crazy warning about voiding your warranty
3. Change the setting of “layout.css.dpi” from -1 to 96 (or 72)
4. Now all should be fine in the CSS/Font world

Straight from the ColdFusion Documentation

You can change the port on which the built-in web server runs.

To change the port for the built-in web server:

1. Back up the jrun.xml file.
This file is in the cf_root\runtime\servers\default\SERVER-INF directory in Windows, and in the cf_root/runtime/servers/default/SERVER-INF directory on UNIX.
2. Open the original jrun.xml file for editing.
3. Change the port number specified in the WebService port attribute (near the bottom of the file):
<service class=”jrun.servlet.http.WebService” name=”WebService”>
<attribute name=”port”>8500</attribute>
<attribute name=”interface”>*</attribute>
<attribute name=”deactivated”>false</attribute>
…
</service>
Note: Make sure that the deactivated attribute is set to false.
4. Save the file.
5. Restart ColdFusion.

I love VMware! There is almost nothing cooler than using vmotion to migrate a guest OS to another host, with zero downtime.

I am in the process of upgrading all of my ESX hosts to 3.5 update 1, and I wanted to post some of my notes to remind me (and help others) with some of the bumps I had along the way.

Updating Virtual Center

• After upgrading Virtual Center to 2.5, 3/4 of hosts received the the following error while attempting to connected them to Virtual Center. “Failed to install the VirtualCenter agent service”
  • This would typically happen after the process was around 80% complete
  • To resolve this issue I used the following steps (Thanks to VMwarewolf for the insight)
    1. Login to ESX Server via ssh client as root user
    2. cd /tmp
    3. mkdir vmware-root
    4. Try re-connecting the host to Virtual Center
• One of my hosts had the following error. “Unable to access the specified host, it either does not exist, the server is not responding or there is a network problem”
  • This was resolved by starting the “mgmt-vmware” process, using the following steps
    1. Login to ESX server via ssh client as root user
    2. service mgmt-vmware start

fdupes is a program for identifying/deleting duplicate files residing within specified directories.

How I typically use it to find duplicate files
fdupes -r -n -1 -S /path/of/directory/to/search/for/dups

How I typically use it to delete duplicate files. It will prompt you for which file to delete. You can preserve multiple files by using a comma separated list of values. See documentation for caveats.
fdupes -r -n -1 -S -d /path/of/directory/to/search/for/dups
