Get rid of Passphrase | Apache Server Startup

If you have enable SSL on your Apache Server, you will notice that whenever your start Apache Server with "apachectl startssl" or "httpd startssl" it will ask you for your passphrase, the reason for this is that the RSA private key inside your server.key file is stored in encrypted format, the passphrase is needed to decrypt this file, so it can be read, however this is a pain specially when the server rebooted by itself and Apache didn't start on its own because you are required to enter a passphrase for it to start, this howto will show you how to remove the passphrase dialog, however to take note that removing the passphrase removes a layer of security from you server, now lets go and remove it :)
Step 1 - Remove the encryption from the RSA private key

$ cp server.key server.key.org
$ openssl rsa -in server.key.org -out server.key

Step 2 - Make sure the server.key file is only readable by root:

$ chmod 400 server.key

Now server.key contains an unencrypted copy of the key. If you point your server at this file, it will not prompt you for a passphrase, yay no more waking up in the middle of the night because no one knows the passphrase to teh Apache Server.

Mail server Failover howto

Sometimes we need a mail server failover, because if you don't when your mail server went down you won't be receiving any mail and we all know how important email is this days, one way of doing mail server failover is through Domain Name Server (DNS).

By defining your MX record likeshown below, If the preferred mail server which is mail.review-ninja.com went down, mail will be sent to the secondary server mail.review-ninja.org, it is also advisable to host the secondary mail server in another location you will also need to configure the second mail server as a relay with a long retry time so that it will accept mail and try to relay it to the main mail server depending on how long you set your retry time.

To define MX records with different priorities.

; zone file fragment
IN MX 10 mail.review-ninja.com.
IN MX 20 mail.review-ninja.org.
....

Windows Vista Games | Explorer

Been using Windows Vista for a while now, its not a great operating system as I think XP is is better than Vista, however it works for me most of the time on my laptop, I mainly use it for playing games but I am disappointed from time to time as I can't run some games I use to play on my XP system, anyway while browsing through my Windows Vista I discovered Windows Vista Game Explorer.

The Windows Game Explorer is a new feature on Windows that let you manage your installed games on your computer, it provides the user control panel view of the installed Windows Vista games, Icons view for each game provide easy access to the games and offer detailed information about each, such as a game's publisher and developer, which version of the game you own, when you last played, box cover art, and the release date, genre, and rating for each game. You can use this information to sort and organize your games in meaningful ways, When you first start up Windows Vista only the default games show up with big icons which makes identification easier. if your asking why use the Windows Vista Games Explorer to manage the games installed on your Windows Vista computer, you will want to use to use it because it is easier to manage and keep all those icons on one place, specially if you have lots of games installed, do take not howveer that not all games are suppoprted I would guess its safe to say that unpopular agems are not supported, however you can still add them to Windows Vista Games Explorer by moving the directoy manually to the explorer folder.


Note: You can find Windows Vista Games Explorer listed on the Start menu.

Backup | Linux | Unix | Flar howto

What is Flar ?

The flar command is used to administer flash archives. A flash archive is an easily transportable version of a refer-ence configuration of the Solaris operating environment, plus optional other software.

Example of flar command on creating a Flash Archive

flarcreate -n [name I put hostname here] –x [exclude folder or files] [name of the archive.flar]

That’s it, you can burn the flar archive directly to a DVD and boot from it, of course it would depend if your image can fit on one DVD, another option is too boot it on a shared NFS drive.

The Samsung U800 has a mettalic finish which gives it a classy look, the phones feel solid and doesn't feel like cheap plastic like some of the mobile phones out in the market. Samsung also used a very good keypad on the Samsung U800 similar to the ones used in Motorola Razr's handsets except the ones on Samsung U800 is ver reposive, the keys are large which is very convenient for texting, specially when you have large fingers.

Feature wise the Samsung U800 has all the things you need on a basic phones today plus a little bit more, the Samsung U800 is a Tri- Band phone it supports GPRS and HSPDA, its has dual cameras one in front for video calling and on at the back the main camera a 3 mega pixel resolution camera, the image quality of the 3MP cameras is very good, The processing, sharpening and colour detail produces good results and the camera interface is easy to use and quick for finding settings so you don’t miss anything, however video recording fared less, at a frame rate of 15 fps doesn't really impress. Playback of the recorded video showed footage that was jumpy and bitty, the Samsung U800 also has a built in FM rreceiver, Samsung U800 also supports MP3, WMA, AAC, AAC+,e-ACC playback and it has a 1000mb internal memory and expandable using a Micro SD, the Samsung U800 has Bluetooth v2.0 conncectivity, the Samsung U800 handles all the common types of messages, SMS, EMS, MMS and emails, and you can store 500 SMS, 30 push messages, 200 broadcast messages and 30 configuration messages on the available 1GB memory., it also has an bult in speaker phone.

Xiaonei | China's Facebook | Xiaonei Social Network

XiaoneiI was browsing and accidentally came to this Chinese social networking site called Xiaonei, I find it funny that the interface of Xiaonei is feel totally the same as if your actually browsing Facebook, it even called itself the "Facebook of China" its just like a perfect clone of Facebook, out of curiousity I did more research about the site and found out as of November of 2007, Xiaonei has become China's largest online community website among universities with more than 8.8 million active users, Xiaonei.com is also considered to be the most powerful student social network service in Mainland China, in comparison to Facebook, Facebook still had a lead over Xiaonei , as Facebook has 2.245% of global internet users logging on to its sites daily while compared to Xiaonei's 0.084%, I wonder if profiles on Xiaonei's social network are being monitored by the Chinese goverment, sort of to keep an eye on the College kids and make sure their not planning anything. :) www.xiaonei.com

This is an old document I created for myself so that I wouldn't forget which I did anyway hehe.. this is simple troubleshooting guide for Veritas disk using VX commands, this covers Enabling, Disabling, Mounting, Fsck, Umount and Querying disk.

Troubleshooting VXFS -

Type to see if disk are disabled(offline) or enabled(online) use:

# vxdg list

If disk is disable you will need to unmount the disk then deport and import the disk use:

# umount

# vxdg deport

After deporting the disk you will need to re-import the disk use:

# vxdg import

If re-import/import of the disk fail or gives and error you might need to ask Veritas to rescan use:

# vxdvtl enable

Note: After running “vxdvtl enable” and you still encounter error when importing, you might also need to run “devfsadm” to load every driver in the system and attach to all possible device instances.

After successfully importing the disk, you will need to check the status of the re-imported disk usually it would be offline/disabled state use:

# vxprint –thg

After confirming that disk is in disabled state, enable the disk use:

# vxvol –g startall

Then recheck the status of the disk, to make sure the disk is enable and it is online use:

# vxdg list

# vxprint –thg

Then run fsck on the disk

# fsck -F vxfs -o full

Then remount the filesystem, usually you can also check the vfstab/fstab to know what are the disk path and mount points

# mount –a

To show and identify disk use on the host use:

# vxdisk -o alldgs list

Hope you find this usefull.
