openSUSE and iMac G3

If you have an iMac G3 and want to install Linux (instead of throwing it out of your window and kills 2 people :P), you may want to try openSUSE. From my experience, openSuse is the best distro for it. What about other distro? Well, i've tried Ubuntu. It is not suitable for this type of iMac. YDL? The installation went smoothly but i had to tweak the X before it worked. One caveat though. If your iMac doesn't have DVD drive, you have to install via internet. First you have to download the install iso and burn it to CD. Boot from the CD and there's menu for you to choose. Choose installation and update. For more info on this, click here.

You will be asked for repository IP address. You can put name address instead of IP. Then, you will asked for directory for packages. Enter the directory. You can find them here. Please choose a repository near you.

Any question regarding installation, just ask here. Maybe I can help. :)

upgrading zlib

I have to upgrade my zlib to version 1.2.3 to upgrade clamav 0.93. If you have recent version (after July 18,2005), you might have it installed already. For older distros, upgrade is a must to avoid security vulnerabilities in 1.2.1 and 1.2.2. You can download the source code here : http://www.zlib.net/zlib-1.2.3.tar.gz

Install from source.
1. unpack the source : tar xzvf zlib-1.2.3.tar.gz
2. change to source dir: cd zlib-1.2.3
3. configure it: ./configure --shared --prefix=/usr
4. 'make' it: make
5. install it: make install (this will install the library in dir /usr)

Extra check:
1. Go to /usr/lib and check whether symbolic links are ok :
[root@proxy lib]# ls -l libz*
lrwxrwxrwx 1 root root 13 May 16 06:29 libz.so -> libz.so.1.2.3*
lrwxrwxrwx 1 root root 13 May 16 06:29 libz.so.1 -> libz.so.1.2.3*
-rwxr-xr-x 1 root root 82305 May 16 06:29 libz.so.1.2.3*

If old libraries are still lying around or libz.so and libz.so.1 point to old library e.g libz.so -> libz.so.1.2.1, delete them.

That's all there is to it.

Installing CentOS 5.1

Hi all,

I am installing CentOS 5.1 to a machine at my friend's office. I had to download 7 ISOs beforehand but it needs only 5 CDs for complete installation (depending on what packages I want to install). I might have downloaded the DVD iso but since I don't have DVD-RW drive, I chose to download the CD ISOs.

The machine is HP Proliant 350 G5 with Intel Xeon processor and it is a 64-bit machine (as all modern Xeon processors are). The machine has been installed Fedora Core 5 before and it had many problems as FC5 is designed for desktop and not server. This should be expected. The machine will be used for database, dhcp and DNS server.

Compiz-Fusion on Mandriva Spring 2008

Upgrading Mandriva 2008 to Mandriva 2008.1 aka Mandriva Spring

Screenshot of KDE 4 on Mandriva Spring 2008

Here are the steps to upgrade mandriva 2008 to 2008.1 via online repos.

1) Back up the current urpmi.cfg
2) Change the repos mentioned in urpmi.cfg from 2008.0 to 2008.1
3) Run urpmi.update -a to verify repos
4) urpmi --auto-update -v

If there are problems with dependencies, remove the old versions (notably KDE4 as in my experience, yours maybe with different packages). Then in some cases you have to run this command:

5) urpmi --auto-select

Relax and sit back while watching the packages being upgraded. For my system, almost 1600 packages upgraded. Lastly, you will be instructed to reboot the system because of kernel and dbus upgrade. So far the new system is running smoothly without problem.

My history of commands

Based on kagesenshi's post titled Me! Me!, I also want to know what commands were used by me regularly. So:

[zamri@localhost ~]$ history | awk '{a[$2]++ } END{for(i in a){print a[i] " " i}}'|sort -rn|head
126 ssh
100 ls
97 smbclient
86 cd
76 su
58 wine
48 ping
35 joe
32 exit
17 ps

There you go. The ouput isn't surprising. I did lots of ssh to my servers and wine (ahaaa!! surprise!), I played windows games a lot for the last 4 months. Now I stop playing 'em completely. It is boring when you always win. :P

     entity converter

   - More efficient scanning of HTML files
   - Many other improvements

   - NEW CONFIG FILE OPTIONS: MaxScanSize, MaxFileSize, MaxRecursion, MaxFiles
   - ** THE FOLLOWING OPTIONS ARE NO LONGER SUPPORTED **: MailMaxRecursion,
     ArchiveMaxFileSize, ArchiveMaxRecursion, ArchiveMaxFiles,
     ArchiveMaxCompressionRatio, ArchiveBlockMax

Well... happy upgrading!. :)
