this will show the last 10 lines of a file (messages in this example) and monitor the file for changes, press ctrl-c to exit

tail -f /var/log/messages

create a loop file (replace 1024 with the size in MB)

dd if=/dev/zero of=loop_filename bs=1M count=1024

mkfs.ext3 -F loop_filename

Check fragmentation of XFS filesystem (50% is not bad really, change sda6 to your xfs partition)

xfs_db -c frag -r /dev/sda6

Kill a stubborn process, #### is the process id (PID)

kill -9 ####

sudo ln -s /var/www/mythweb/data/ /var/www/

Seems this one was actually throwning a nice error in the Apache2 error.log…

[Thu Mar 05 05:02:58 2009] [error] [client 192.168.0.269] File does not exist: /var/www/data, referer: http://tv/mythweb/weather

Wheee… MythWeb weather works for me now (Mythbuntu 8.10)

Did some poking around with the module code. In the file /var/www/mythweb/modules/weather/handler.php It read:

// Get configured WeatherScreens from the database
$sh = $db->query(’SELECT screen_id, draworder
FROM weatherscreens
WHERE hostname=?’,
$_SESSION['settings']['host']);

Changing the last line to the following like I found in a similar section in init.php to:

hostname);

actually showed me my current conditions and three day forcast… the doppler radar image is missing though.

Hope it helps someone out there.

Being a packrat, i still had AVG-Free-Edition-7.-5.487 (from 9-11-2007)

click click… This version has expired…

date & time… 9-11-2007… click click… bingo

basically just set the date and time back to a time near the version you want.

Still updates fine, works much faster with a lower footprint.

find older versions at: http://www.oldversion.com/program.php?n=avg

So, i went into services (services.msc), scrolled down to Windows Firewall/Internet Connection Sharing (ICS), right clicked it and chose start… received an “Error 5 Access is denied”… wtf?!?

Next i was off to google, came across a LENGTHY thread… http://forums.techguy.org/4034641-post37.html … that is the portion of the thread that finally solved it for me.

Basically i was somehow missing some registry keys…

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile]
“EnableFirewall”=dword:00000001
“DoNotAllowExceptions”=dword:00000000
“DisableNotifications”=dword:00000000

After entering those, i rebooted and all was well.

security.dialog_enable_delay

Hurray, no more delay :)

Normally I would have to do a lot of manual calculations as I found no software available to do a quick conversion. So, I wrote a web page that does it for me. I can be found at: http://www.conradshome.com/html2bgr15/.

Enjoy :)

Sure you can disable it, but i wanted it GONE. Here is how… open regedit, and browse to:

KEY_CURRENT_USER\Software\Mozilla\Firefox\Extensions

delete:

{3f963a5b-e555-4543-90e2-c3908898db71}

Restart Firefox and your done :)

Adding /flushdns to this command will purge the local DNS resolver cache, this is handy when a website has VERY recently moved. I learned this command after my webhosts automatic DNS update failed renewing my account. Other computers in the house could see the website, but this one machine would not. After flushing its DNS cache, all was well.

Another switch is /displaydns, this lists all entries in the cache (including recent entries from the hosts file).

In Linux, the nscd daemon manages the DNS cache. To flush the DNS cache, restart the nscd daemon. To restart the nscd daemon, use the command `/etc/init.d/nscd restart`.
