HP Solution Center failed to open

Recently, the HP Solution Center suddently stop working. When I launch HP SolutionCenter, nothing happens. In the error log, I see the errors:

Product: SolutionCenter -- Error 1904.
Module C:\WINDOWS\system32\Macromed\Flash\Flash9b.ocx failed to register.
HRESULT - 2147220473. Contact your support personnel.

What seems to have happened is the following:

1. Adobe Flash is updated to version 10. This cause Flash9b.ocx to be deleted from C:\Windows\Flash
2. HP Solution Center is apparently dependent on Flash9b.ocx, so it stopped working.

Here’s how I got rid of the error.

1. Uninstall HP solution center because HP do not allow you to reinstall the HP Solution Center. Instead, we have to uninstall so we can install the HP Solution Center again.
2. Reinstall HP Solution.

If you examine C:\Windows\System32\Macromed\flash, Flash9b.ocx is back even though we have Flash10.ocx. If you examine the event log, there is the same registration error again (you can’t register Flash9b.ocx because there is a later version), but HP solutions apparently works.

Unable to connect Linux computer to Dlink DI-624 router due to ipv6

Recently, I installed Ubuntu 6.06 on an old laptop. Much to my surprise, the Dlink DWL-G650 wireless card was recognized. Much to my annoyance, the wireless did not work. Here’s what I did to fix the problem. I open up a terminal window and type iwconfig.

lo no wireless extensions.

eth0 no wireless extensions.

ath0 IEEE 802.11 ESSID:”"
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Bit Rate:0 kb/s Tx-Power:20 dBm Sensitivity=0/3
Retry:off RTS thr:off Fragment thr:off
Power Management:off
Link Quality=0/94 Signal level=-95 dBm Noise level=-95 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

sit0 no wireless extensions.

From the result, it would appear that the drivers were found and loaded (or we won’t be getting ath0). The access point “Not-Associated” is more troubling though. I selected System->Admin->Networking and the network card and looked at the Ath0 properties. I had enter the WEP earlier, but I realized that I had enter the WEP Key in hex but set the type to ASCII. I was sending the wrong key (note that I had also set properties to use DHCP).

With the correct key, I enter iwconfig again:

lo no wireless extensions.

eth0 no wireless extensions.

ath0 IEEE 802.11g ESSID:”Literbox”
Mode:Managed Frequency:2.422 GHz Access Point: 00:12:59:19:17:5E
Bit Rate:48 Mb/s Tx-Power:18 dBm Sensitivity=0/3
Retry:off RTS thr:off Fragment thr:off
Power Management:off
Link Quality=13/94 Signal level=-82 dBm Noise level=-95 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

sit0 no wireless extensions.

Now notice the access point’s MAC address is returned. However, the wireless is still not working. I did a dmesg and see the following error message:

[17179906.596000] ath0: no IPv6 routers present
[17179931.316000] ath0: no IPv6 routers present

So what seems that the router a Dlink DI-624 Rev C is not compatible with IPv6 protocol. I am assuming this because I can’t find any info on the Dlink website, but some site indicated that DI-624 Rev D handled ipv6. In any case, this mean I have to turn off ipv6. Follow the instruction on this link to disable ipv6.

Installing LAMP on Ubuntu

I found the following article that was helpful in installing LAMP. The only thing I change is that  PHP is now up to version 5.

http://strdoc.net/ubuntu-apache-php-mysql-server/ 

Using Synaptics, I was able to install the whole LAMP suite in less than 10 minutes. 

I tested the apache server and PHP by writing a helloworld php script and placing it in /var/www.
