Installing Sun VirtualBox on FreeBSD 7.1/amd64.

Today I decided to install Sun VirtualBox on my FreeBSD 7.1/amd64. The installation from ports is straightforward as usual.

#csup -g -L2 /etc/ports-supfile
#cd /usr/ports/emulators/virtualbox
#make install clean

I got stuck when it failed to fetch this file Dev86src-0.16.17.tar.gz.

#wget ftp://ftp.freebsd.org/pub/FreeBSD/ports/distfiles/Dev86src-0.16.17.tar.gz
#mv Dev86src-0.16.17.tar.gz /usr/ports/distfiles/
#make install clean
#hash -r ; ldconfig

Mount proc:
#mount -t procfs proc /proc

Load vbox driver module:
#kldload vboxdrv.ko
#kldstat | grep box
13    1 0xffffffffab46a000 3fb0e    vboxdrv.ko

Launch vbox from menu or command:
#VirtualBox

Done.

Virtualbox is now available in ports!

This could be one of the bestest news I’ve heard in months!!

Excerpt from miwi:

“Today Virtualbox was committed to the FreeBSD ports tree. After a lot of work we had a good discussion today about how stable Virtualbox is, and after the CTF with take6 we got a lot of good feedback, so it was time to commit.”

Read it here.

Woohoo!!

Fitter happier.

Yea, there has been a lack of update. I was busy with WebLogic, and Devin.. oh well, he only writes material that meets a certain literary and relevancy standard and he is not that prolific. Lol. Guess you’ll never find him writing anything that will be tagged as rant

Few things happened last week..

Weblogic completed:
Am done with the project last week, which is cool. Haven’t gone through the UAT session with the users yet, so until they say “All’s good”, guess I’ll have to keep my fingers crossed. Weeee!!!!



I lost my handphone:
Yes, my cheap handphone. I can’t believe someone would want to steal it. I bought the handphone for about 300 – 400 bucks, so am surprised that someone would be so keen to steal it. How much does it worth really? 2 small packets of weed? Am not bothered about the phone. Well alright, I am bothered, because it costs money. But what I care the most is the data inside the phone. My contacts, my messages, heck I even have a few audio clips of my cat purring recorded with that phone. Oh well. Fuck you, thief.

Medical checkups:
I had a couple of medical checkups performed last Tuesday and Thursday. Last Tuesday I got all wired up for the holter monitoring test. It was something like a 24 hours of ECG (electrocardiogram) to monitor the electrical activity of my heart. I couldn’t take showers during the procedure because it’ll damage the device. So yeah, am pretty happy with the fact that I don’t have to shower and not feeling guilty about it. Am just plain lazy sometimes.

And last Thursday, I got up very early in the morning and headed to the General Hospital to get my brain checked. It was a quick EEG (electroencephalography), prolly around 20 minutes where I had to blink my eyes numerous times, with bright light flickered directly on me for a few minutes and inhale/exhale profusely for 5 minutes which was tiring since am asthmatic. And oh my, I looked horrible with my hair glued on with all the wires. And I looked even worse after the guy pulled them out. I looked like a woman who is trying too hard to impress a guy by applying extra hair gel. You know the type of hair gel that will make your hair hard and stiff? Gah. I hate it.

I’ll be getting the results this April. I hope everything will be fine, since am always fine, and anyway I agreed to go through all of these medical procedures because my sister told me to. Nothing serious.



FreeBSD upgrade:
Yeah, finally! Upgraded to 7.1. I did it last Saturday, and I was thinking to update this blog on Sunday, but guess what, the update went fine until suddenly I failed to start the X server. Hmmm.. now that’s weird, because this was not the first time I did a FreeBSD upgrade, plus, this was just a minor version upgrade, so what could go wrong? Building world, kernel and installing them went perfectly well. I didn’t forget to run mergemaster, the machine booted up well. Spent a day changing the theme, and all of the sudden it failed (yeah, ironically it failed after I spent the whole day beautifying my desktop, why didn’t it fail sooner?). I realized that it failed just after I ran portupgrade to upgrade my Opera and Firefox. Probably the modules are not synced, am not sure.

I spent the next 48 hours running portupgrade numerous times, until I finally decided to rebuild perl, xorg and xfce4. But to my surprise it failed. I reinstalled my xfce4 and its gang one by one, so they’ll all run on the same version. Reboot the machine and voila, am back. Still, some of my installed packages are broken, so I had to fix them.

So they say, if it ain’t broken, don’t fix it. I could’ve just stick to FreeBSD 7.0 and save the 48 hours from the agonizing pain of troubleshooting my machine. But seriously, it was worth it. The performance is so much better, XFCE 4.6 is brilliant with more new features and yes fellas.. flash 9 works

He got engaged:
Yes, he finally got engaged. AmazingCongratulations.

So it’s Gnome, Linus?

So much of his Nazi comment that ruffles the feathers of GNOME community last time.

I have always been a loyal user of XFCE4, but if I had my druthers between Gnome and KDE, I’d prefer Gnome. KDE is nice, I love some of KDE apps, but imho, it’s kinda bloated. Very pretty, way prettier than Gnome, but bloated. But of course, I’d go for Enlightenment if I want some real fancy stuff on my desktop.

Anyways, am not any DE/WM fanatic. I just love to keep my desktop clean and minimal.

I lol’ed.

WebLogic 10.3 on FreeBSD?

I wish.. lol.

Am very new to weblogic, so am pretty excited to try it on my FreeBSD at home. Well ok, I just managed to install it, but couldn’t get it run. Bleargh. The problem is with the LD_LIBRARY_PATH I think. There’s no native directory under <WL_HOME>/server, so it’ll complain about the missing path when you try to start the domain or node manager. Pfftttt. I’d love to know how to fix this

But anyways, here’s how to install WebLogic 10g on FreeBSD 7. Just installing it, but it doesn’t work lol. I don’t know why I even bother writing this.

1 – FIrst of all, download the installer from the oracle website. Choose HP-UX as the operating system as that’ll provide you with a generic jar installer.
http://www.oracle.com/technology/software/products/ias/htdocs/wls_main.html

2 – While it’s downloading, install eclipse from the port.
cd /usr/ports/java/eclipse && make install clean

3 – Install eclipse WTP. Get it from here:
http://www.eclipse.org/downloads/download.php?file=/webtools/downloads/drops/R2.0/R-2.0.3-20080710044639/wtp-R-2.0.3-20080710044639.zip

Place the zip file at /usr/local and unzip it. It’ll place all the extracted files in the right directory.

4 – After you’re done with eclipse, you’re ready to install weblogic. Am performing this as a non root user.

I use diablo java, so running java -jar server103_generic.jar alone will not work.

My java -version:
java version “1.5.0″
Java(TM) 2 Runtime Environment, Standard Edition (build diablo-1.5.0-b01)
Java HotSpot(TM) 64-Bit Server VM (build diablo-1.5.0_07-b01, mixed mode)

So execute the installer using sun jdk directory to get it running:
/usr/local/jdk1.6.0/bin/java -Dos.name=unix -jar server103_generic.jar

You’ll have to specify the Dos unix name, else you’ll get the insufficient disk space error, which is very annoying when you actually have tons of free space. You may get lucky with this and the installation will end successfully. As for me, it stuck at 74% while creating the sample domain.

$ /usr/local/jdk1.6.0/bin/java -Dos.name=unix -jar server103_generic.jar
Extracting 0%……………………………………………………………………………………….100%

The error was out of memory exception, so I decided to reinstall it. But first I have to uninstall it first since weblogic detected that it has already been installed at the target directory.I run the installer with the following command:
/usr/local/jdk1.6.0/bin/java -Xmx2G -Dos.name=unix -jar server103_generic.jar

Installation complete!

Alright, now the installation is done, you might wanna try to start the sample domain.

Ahah! Now this is the part where I got unlucky.

It complains that the port is being used, when it’s not! Hmmmmphhhhh!

Well actually there are other errors came out before that but am too lazy to look at it. Lolz.

Now if you try to create a domain, you’ll get the shared library path error:

Same goes if you try to start a node manager.

Ah well.. think I’ll spare some other time playing around with this. Doing weblogic makes me miss websphere. Lol.

Back them up.

I learned my lesson the hard way. Last 2 years I bought a 120gb WD hard drive and used it for about 6 months before it suddenly died on me. 6 months, it was still covered by the warranty, but I chose not to return it for an exchange of a new one. I have tons of data inside but out of all data, I just need prolly around 30% of it. The rest, I can say goodbye with tears in my eyes. I still have the hard disk, kept nicely inside my wardrobe. When I have the chance, I’ll bring it back to live!

I love Maxtor hard drive. I still have one old Maxtor hdd that I’ve been using for almost 8 years running. In fact I used to have 2 of them. One has failed, but it is completely acceptable since it has served me for over 6 years.

Currently at work am preparing backup scripts for some servers. I find that backing up the entire directory of windows virtual machine is kinda annoying. Am thinking of what would be the best way to shutdown windows without using the force flag? Urgh. I wish I can just init 0.

At home I use a simple script that I wrote to backup directories. Basically what it does is it checks the content of both source and target directories, and any files/directories that are not available at the target location will be copied, creating a duplicate copy of the original directory. It’ll also generate a log (diff.log) to record what files that have been copied over. I use it to backup log files, nothing in giga size.

#!/usr/local/bin/bash

SOURCE=”$HOME/personal/script/cmp2dirs/diffmv/cmp2″
DEST=”$HOME/personal/script/cmp2dirs/diffmv/temp”
sSOURCE=`echo $SOURCE | awk -F/ ‘{print $NF}’`
sDEST=`echo $DEST | awk -F/ ‘{print $NF}’`
DATE=`date +”%v”`

echo “Directories comparison on $DATE” >> diff.log

diff -rq $SOURCE $DEST >> diff.log

s1=”Directories comparison on $DATE”
s2=`sed ‘$!d’ diff.log`

if [ "$s1" != "$s2" ]; then
sed -n ‘/’”$date”‘/,$p’ diff.log > copy.out

echo “Directory(s)/file(s) copied from $sSOURCE to $sDEST:” >> diff.log
f1=`sed -n ‘/^[Only in ]* /s///;s/:.///p’ copy.out`
f2=`sed -n ‘/Files/s/^.*Files.(.*) and.*$/1/p’ copy.out`

IFS=’
‘
cp -vR $f1 $f2 $DEST >> diff.log

else
echo “Directory $sSOURCE is unchanged since yesterday.” >> diff.log
fi

echo >> diff.log
echo “—————————————————————” >> diff.log
echo >> diff.log

exit

The output of diff.log will be something like this:

Directories comparison on 15-Nov-2008

If you’re sleepy, just sleep, don’t do your work.

I was so damn sleepy last night that I could hardly remember what I did before I went off to bed, but I do remember one thing – I switched off my external hdd without checking if I have safely unmount it from Windows. Actually I was too lazy to check and I forced myself to believe that I have unmounted it.

Back in the office this morning I plugged in the hdd, and surprise, surprise.. Ubuntu recognized only one of the partition (I have two, ‘Work’ and ‘Personal’). It gave me an error stating that it failed to mount due to unclean shutdown.

I remember having the similar error with the same hdd, even worse actually since both partitions failed to be mounted. But that happened after I borrowed my hdd to a colleague who is running on Vista, and it is pretty common to have that error once you try to boot it back on any *nix system. Back then I was using freebsd, and I normally mount it manually using the “mount -t ntfs /dev/da0s5 /mnt/hdd” command. ntfsfix didn’t solve the error, but ntfs-3g worked like a charm.

And so I tried to mount it manually on Ubuntu using ntfs-3g command, but it gave me this error:
fuse: mount failed: Invalid argument

I installed ntfsprogs and tried to fix with ntfsfix. It completed successfully, but my attempt to mount the partition still failed.

I mounted it back on Windows, and checked on the disk management. While it recognized my ‘Work’ partition as ntfs, my ‘Personal’ partition was recognized as raw and unlabeled. So I labeled it, and run chkdsk against the volume. Mount it back on Ubuntu, and it worked! Yay

Moral of the story is - Don’t work when you’re sleepy.

osx86 on vmware server.

My 3rd attempt in installing osx86 onto my vmware server ended successfully. I know there are a number of guides/howto on this topic, but think I’ll just post the settings that I used in order to get it work.

Previously on my 2nd attempt I mounted the osx86 iso file using the mount iso command, and point the CD-ROM to the mount point but it just didn’t work. So I skipped the hassle and burned it straigt onto a DVD.

With the above setting I don’t have any problem in booting the DVD. I did configure the VM BIOS though just to improve the performance.

Boot the CD, and the launcher will start. After creating a partition using the Disk Utility, I relaunched the installer: Installer > Restart.

Upon rebooting, you may or may not get a ‘b0 error’. It depends on your boot sequence setting. To solve this, just go to BIOS and set your CDROM as the first boot device. F10, and you’ll get back to the launcher again. This time, you can proceed with the installation. At the end of the installation, the vm will restart. If all goes well, Mac OS X should boot perfectly.

Done

Install WAS Base/ND v6.1.0 on Ubuntu Gutsy.

There are 2 things that need to be configured in order to install WebSphere Application Server Base/ND on Ubuntu Gutsy successfully – tested using WAS Base/ND v6.1.

1 – Ubuntu Gutsy links sh to dash instead of bash. There won’t be any error during the installation of WAS itself, but you will not be able to create any profile, so it’s useless. Two ways to fix this, either remove the symlink and relink it to bash, or change the shebang line inside the WAS install script from #!/bin/sh to #!/bin/bash. Changing the default shell from dash to bash may cause your system slower since dash is lighter than bash, but I think it is hardly noticeable. More info at https://wiki.ubuntu.com/DashAsBinSh.

2 – This applies to WAS ND, I didn’t encounter any issue with Base. If you’re having a problem in getting the dmgr server up, and the error in the SystemOut.log is something like this:

…

Chance is you have not assigned an IP address for your hostname, except for the default 127.* address. If this is the case you won’t be able to federate nodes to the Dmgr as well. So edit your hosts file. Since Edgy the hostname was split to 127.0.1.1, so you will see 127.0.0.1 is assigned to a localhost, and 127.0.1.1 to your hostname. Assign your hostname to 127.0.0.1 as well, and problem solved. But if you plan to do some nodes federation, then assign an IP for your hostname. Your hosts file should look something like this:

127.0.0.1 localhost YourHostName
127.0.1.1 YourHostName

Done.

This is not new but anyways..

FreeBSD 7.0 is out!
