Freebsd as l2tp client to Mikrotik l2tp server

July 2nd, 2009

I just wondered if anyone has tried this and gotten it to work. I tried it a while back, and even though it seemed freebsd was configured to be an l2tp client, it could not connect to my existing mikrotik server.

I forget which port I used. Might have been /usr/ports/net/sl2tps Will give it another shot and in the meantime see if anyone comments.

Google chrome pauses on my laptop

May 11th, 2009

I’ve gone around installing Google Chrome on each of my workstations, because it is much, much faster than Firefox, which lately has been driving me nuts. My favorite is closing Firefox, which in itself takes longer than it should, waiting a few moments, then reopening it, only to be told “an instance of firefox is already running.”

On one of my computers, it seems like Chrome causes annoying pauses, however. I notice it the most when I slide the scroll bar on the right. The problem gets worse over time, and I have to restart Chrome to go back to normal. There is no corresponding spike in CPU use or memory use. Very puzzling.

I should note that this laptop has a solid state disk, and XP has some issues with pausing on solid state disks. However, I have applied some of the tweaks listed at OCZ’s website to prevent XP from doing the kind of disk access that doesn’t work right on solid state disks. And this problem only occurs in Chrome, not Firefox.

Rosetta stone error in Vista 1117

April 16th, 2009

Brand new installation of Rosetta Stone v. 3:

1117

An error occurred in the speech component. Please restart your browser and start Rosetta Stone again. If the problem persists, please restart your computer.

This error message is explained in the Rosetta Stone web site’s support FAQs. It’s because the hosts file in Vista is, well, very strange in its default configuration. Instead of a localhost of 127.0.0.1, the localhost is ::1. RS suggests adding the proper entry, described here.

Since literally every user of Rosetta Stone in Vista must encounter this error, couldn’t the software be a little more helpful? As in, hey, the hosts file is incorrect, please add the correct entry for localhost? Or hey, here you go, a link to our support article on this…

Wordpress hacks

April 7th, 2009

Wordpress has a lot of little problems that you can usually fix by doing a search in the forums.

Wordpress blog stats: in some themes, this will not work until you add the following to footer.php, right before the closing body tag </body>, in the design editor:

<?php wp_footer(); ?>

If you use widgets, sometimes the design editor is not useful, because widgets override it. But there is no administrative way to manage the content of the widgets. Instead, you edit wp-includes/widgets.php directly.

The Temp folder is on a drive that is full or is inaccessible

April 6th, 2009

Another carryforward:

When you go to run Adobe Reader 8 installation program, you get “The Temp folder is on a drive that is full or is inaccesible…” The problem occurs, once again (network printers being another instance), only if you’ve disabled User Account Control. Problem is described by Adobe here: http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=333643

You don’t have to reenable UAC if you don’t want to reboot your computer–you can run the installer in XP compatibility mode.

Most versions of Vista won’t play DVDs without 3rd party codecs

April 6th, 2009

Note: this was published a couple years back, but it gets a lot of hits so am bringing it forward:

From the mouth of Microsoft. You must have Home Premium or Vista Ultimate to watch DVDs using Windows Media Player 11. Their official description of this problem includes no link to a compatible dvd codec. What a sense of humor they have:

DVD Playback Options for Windows

If you are running Windows Vista Home Basic, Windows Vista Business, or Windows XP, you must install a compatible MPEG-2 decoder (also known as a DVD decoder) before continuing with the following activities.

  • Playing a DVD
  • Playing a recorded TV show
  • Playing video files that were encoded with the MPEG-2 codec (.mpeg, .mpg, and some .avi files)

For Windows Vista
DVD playback capabilities are available in Home Premium and Ultimate editions of Windows Vista and will be available for purchase for other editions when the final version of Windows Vista is available.”

I’m running Vista Business, so no DVDs for me without some extra work. I downloaded the recommended Video Lan client for Windows, but when watching The Dark Crystal all I see is an orange screen. It makes me realize that moving images are an important aspect of movie-watching.

Online forums suggest rolling back your driver. The same driver for my ATI x1600 without which I can’t run the Aero display interface. ATI is to have new driver for Vista by end of month, maybe…

My Computer takes forever to open

April 2nd, 2009

An oldie but goodie. This can happen when My Computer is looking for a mapped network drive that it can no longer find, presumably because the target is no longer in the picture or the mapping is otherwise incorrect.

Downgrade to upgrade

April 1st, 2009

To fix my problem with the 2.7 wordpress blog giving blank pages, I downgraded from 2.7.1 to 2.6.5. So it’s an upgrade downgrade.

I like the old interface better, too! But now it bugs me all the time to upgrade. Ha ha.

By the way, to upgrade or downgrade wordpress from the command line:

In some other location, i.e., the desktop

/usr/local/bin/wget http://wordpress.org/wordpress-2.6.5.tar.gz
tar -xzf wordpress-2.6.5.tar.gz

Now switch to the dir you want to install WP in:

rm -r wp-admin/
rm -r wp-includes/
leave wp-content alone - delete wp-content from the installer pack as it seems to be unnecessary in an upgrade, and you don’t want to overwrite your content in the next step
cp -r /wordpressinstall files .
as root: chmod -R 777 .

Go to url/wp-admin subdir and click through. Presto.

Yamaha receiver HTR-6040 shuts off spontaneously and says check sp cable

March 25th, 2009

Every piece of equipment I buy develops some error. Usually fixable, and though I could get mad about it, since I deal with troubleshooting issues all the time, I can’t get mad, for my own health. But tonight, when a brand new Yamaha receiver started shutting off in the middle Death Proof and saying “check SP cable,” I briefly contemplated what it would look like launched from a trebuchet and vaulted into the night sky.

This one turns out to be simple. Glad I’m such a master of my emotions. Plus I don’t have a trebuchet. Not even a catapult. “SP” means speaker, and fittingly, a lead to one of the speakers had fallen out. I screwed the wire back into the speaker and was in business. So the error message was actually meaningful, a foreign concept to Microsoft software engineering. The receiver probably detected garbage or feedback or something, and shut off to protect itself whenever the volume got too loud.

After installing SP3 in Windows XP, Windows no longer loads

March 25th, 2009

Service Pack 3 installations are causing some Windows XP computers to fail to boot.  The way to get them back is through system restore. There are a number of possible causes, but this one worked on a computer I had in:

If you have an HP desktop with an AMD processor, it has a configuration not approved by Microsoft. To fix this, before installing SP3, type:

sc config intelppm start = disabled

in the Run… window.

This issue is discussed more in depth here, and many places elsewhere.
