InstallVMware Server on Intrepid

paulus — Wed, 05 Nov 2008 04:52:20 +0000

I’m trying to get VMWare Server 1.0.6 working on Intrepid since I need it for my day to day work. Here’s a quick how to :

Download VMWare server from VMWare website. VMWare server is free, but you need serial number which can be requested by registering to -VMWare. Extract the source, it will create a directory called vmware-server-distrib
Download VMWare patch from from here.
To install VMWare, you’ll need linux-headers, build-essentials, and xinetd. Download those from repo by executing the following

$sudo apt-get install build-essential linux-headers-2.6.27-7 xinetd

Note that the version of your linux-headers may differ. Up to now, my intrepid uses kernel 2.6.27-7-generic.

Go to the vmware distrib directory, and execute the ./vmware-install.pl

$cd vmware-server-distrib $sudo ./vmware-install.pl

Just use the details, but note that when you’re asked if you’d like to run the vmware-config.pl, select [no]

Extract the vmware-patch

$gunzip < vmware-update-2.6.27-5.5.7-2.tar.gz | tar -xvf -

Go to the update directory and execute the patch script

$cd vmware-update-2.6.27-5.5.7-2 $sudo ./runme.pl

The script will patch the source, and ask whether or not you want to run the vmware-config.pl script. This time, select [yes]. While running the script, I accepted all the defaults value.

I assume that you can configure networking on your own.

Environment :
- Ubuntu 8.10 Intrepid Ibex running kernel 2.6.27-7-generic

I’ve been playing with Ubuntu Intrepid Ibex for 2 days now, and I could say that it’s definitely a significant improvement. Here’s a few thing that I’ve noticed during these short time of period

Network Manager Improvement

Ubuntu recognizes the mobile broadband boom, and lots of people using 3G network to browse the internet. In the last release (Hardy), configuring 3G could be a hassle, especially for those who are new to linux. Now in Intrepid, it recognizes my E220 modem immediately after I plugged it in, launch a wizard to help me choose which provider I’m using, then create a network configuration for that. All I need to do is to configure it to use my username.

The beauty of it? It doesn’t even need additional software. (Well, 3G doesn’t require additional software in Hardy for 3G, but those requires configuration on wvdial, ppp, etc). Integrating it to network manager is brilliant. Back in hardy, everytime I launch Firefox after connecting to 3G network, it wasn’t aware that I’m online and I have to manually untick the “Work Offline” mode. Now, that pain is gone

There’s also additional section in network manager for DSL connection, but since I don’t have DSL connection, I can’t give it a try.

Tabbed File Manager

Intrepid includes Nautilus FM version 2.24.1, now comes with tabs. Just like a browser, now you can browse to different part of filesystem, without have to open several instances of Nautilus. Good feature.

Encrypted private folder

This is a feature to allow user to create an encrypted folder in their own home directory. Unfortunately, it doesn’t comes by default. You have to install it manually (use apt-get or synaptic to install ecryptfs-utils). Worse, you can only configure it from terminal (which probably the first reason why Ubuntu doesn’t include it by default in the first place). Before they can put a good interface into this, I think I’ll stick with TrueCrypt.

There are some other features available like private filesystem, integrated USB startup disk creation, etc, but I haven’t given them a try yet. Will keep posted on that.

Any of you discover a new feature you’d like to share?

Intrepid Ibex

Intrepid Ibex is out !!!

Getting a new (well not new, actually) laptop, Dell Latitude D630, and after finished downloading the new Ubuntu Intrepid Ibex, I decided to give the new Ubuntu a try.Here’s a quick review :

Installation

Installation is fine, as with the last Hardy, it’s also an easy install. Aside from partitioning and time zone, you can probably accept all the default setup. It took me about 30 minutes to install the whole system. Booting is fast, I think it’s slightly faster than my current Hardy (well, probably because my Hardy is already bloated with additional services )

Devices

D630 uses a restricted (proprietary) driver for wireless card, i.e. Broadcomm Wireless. Once you activate the driver and restart the system, it works like charm (probably won’t need restart, but I don’t want to get into a hassle trying to configure it. besides, restarting take less than a minute :p). Display gets 1200×800 out of the box, and is fine. Bluetooth and sound works. One thing that bug me is the that the touchpad response is very slow, probably need some tweaking for that later. Other than that, everything works perfectly !!

Printing

Continuing hardy tradition, printing is extremely easy to setup. Once I enable printer “Show printers shared by other systems” in System -> Administration -> Printing -> Server -> Settings, then I click new, it detects both Xerox Document Center 236 and HP Color Laserjet 3800 available in my office network. I already setup the Xerox using Generic PCL 6/PCL 6XL Foomatic driver, and it prints fine.

To Do List

Last thing I need to configure is vmware. Back in hardy, it required some patches, which will probably the same case with this one. Also will need to check whether presentations work ok to projector.

All in all, this release is satisfying. Back when Hardy is initially released, I need to tweak some stuffs to get sound working in my Compaq V3000 series.

Let’s get Intrepid

Small Network Backup dengan DeltaCopy dan rsync

paulus — Thu, 16 Oct 2008 13:25:57 +0000

Saya punya satu klien dengan jaringan kecil (10 client Windows) dan satu buah Ubuntu server sebagai router + DNS + DHCP + file server. Salah satu requirement yang diminta adalah network backup, dan network backup itu harus bisa diverifikasi oleh client yang bersangkutan (dengan kata lain, dia bisa liat langsung hasil backup-nya).

Untuk network backup, sebenarnya ada beberapa kandidat, antara lain Bacula dan Amanda (secara keduanya gratis). tapi constraint yang saya temukan (dan saya belum temukan solusinya) adalah, karena bacula dan amanda menggunakan protokol samba untuk windows backup, fitur incremental backup jadinya tidak bisa dicapai (entah saya yang tidak bisa configure juga barangkali). Sesudah browsing sana sini, akhirnya ketemu solusinya, gabungan antara DeltaCopy di client dan rsync di server.

Langsung saja ke konfigurasi-nya ya:

Konfigurasi di server

Install rsync dan xinetd di server (rsync secara default sudah ada di ubuntu server, tapi just in case, tetap saya tambahkan di sini )

$sudo apt-get install xinetd rsync

Buat file /etc/xinetd.d/rsync dengan isi kurang lebih seperti ini :

service rsync { disable = no socket_type = stream wait = no user = root server = /usr/bin/rsync server_args = --daemon log_on_failure += USERID }

Buat file /etc/rsyncd.conf dengan isi kurang lebih seperti ini :

log file=/var/log/rsyncd pid file=/var/run/rsyncd.pid [data] comment = public archive path = /data use chroot = yes lock file = /var/lock/rsyncd read only = no list = yes uid = [user yang punya akses write ke path] gid = [group membership dari user] auth users = [user yang akan diberikan akses] secrets file = /etc/rsyncd.secrets timeout = 600

dalam konfigurasi di atas, backup dari klien akan disimpan di folder /data, dan akan ditulis dengan user support

Buat file /etc/rscyn.secrets untuk menyimpan autentikasi username dan password dari rsync. Isi file itu dalam format [username]:[password], misalnya

username:password

Edit file /etc/default/rsync supaya berjalan dengan xinetd, pastikan berisi :

RSYNC_ENABLE=inetd

Restart xinetd server

/etc/init.d/xinetd restart
Konfigurasi di Client

Download Deltacopy dari website DeltaCopy
Ekstrak file dan jalankan setup
Sesudah instalasi selesai, jalankan DeltaCopy Client
Buat satu profile, dan edit parameter-nya (server, path, folder yang ingin dibackup, schedule jika diperlukan, dsb). Hal yang menarik dari DeltaCopy adalah kemampuan untuk scheduling, serta incremental backup. Jangan lupa tambahkan username dan password yang didefinisikan di server pada DeltaCopy Client

Untuk mapping hasil backup client dari Ubuntu ke Windows, saya pasang samba server di Ubuntu.

Secara keseluruhan, konfigurasi-nya sangat mudah. Selamat mencoba

Glassfish Installation On Ubuntu Hardy

paulus — Thu, 11 Sep 2008 07:18:45 +0000

Since one of my responsibility at work is being pre-sales for Sun Identity Manager software, I need a demo environment ready in my laptop for proof-of-concept, presentation, demonstration, and testing purposes. Early on I usually use Tomcat Application Server to host the application. But being a Sun partner, wouldn’t it be nice if the apps is deployed on Sun Apps Server as well? :D. With the new Identity Manager version 8.0 coming to the market, I decided to set it up on Sun Apps Server, known as Glassfish.

So here goes.

Install Sun Java JDK

There are two alternatives for Java in ubuntu, i.e. OpenJDK and Sun Java JDK. In this environment I’m going to use Sun Java JDK.

$sudo apt-get install sun-java6-jdk

Having OpenJDK installed previously, we need to update the system to use the new JDK
$sudo update-alternatives --config java

Install Glassfish Application Server

$sudo apt-get install glasshfishv2

By default, apt installs the apps server into /usr/share/glasshfishv2/ directory, and the web application folder goes to /var/lib/glassfishv2.

Start the application server

$/usr/share/glassfishv2/bin/asadmin start-domain .: 7: Can't open /usr/share/glassfishv2/config/asenv.conf

Now this is weird. I check the /usr/share/glasshfishv2/ and there is no config/ directory in the folder.
For some weird reason, apt seem to forget to configure the application server (or maybe I do something wrong?). After I installed it, i didn’t check the installation, and shutdown my laptop immediately since I need to do something else. Only after I boot my laptop and trying to configure it, I noticed that there are something wrong.

Since this is my first time using Glasshfish, I really don’t know my way around :D. Ask Google, and all references failed. Trying dpkg-reconfigure, failed as well. Being lazy as I am, I took the shortcut, reinstall the damn thing
$sudo apt-get install --reinstall glassfishv2

Finally, there it is. I finally get it right. Fire up my browser and browse to http://localhost:4848/ the admin page appears.

Community Linux on the rise?

paulus — Mon, 01 Sep 2008 14:36:59 +0000

PCWorld released a recap of a recent study showing a stronger ground community-based linux distributions gains in the enterprise market. Quoted from the study :

“Community distributions such as CentOS, Debian, and Gentoo are gaining enterprise respect for quality code, stability, response, and of course, for being “free as in beer” and “free as in freedom”. These community distributions are becoming a more significant market factor with growing enterprise acceptance and use of them”

Apparently more enterprises, especially in Europre, are willing to take chances running community-based distro (as opposed to commercial distro like RHEL or SuSE) using their internally capable resource for system administration, support, as well as application migration, although sometimes they still seek assistance from third-party consultant, which turns out to be cheaper than paying support from commercial-based distro.

Is this the end of commercial-based distro? Well it may be is too early to say so, but commercial distro should start reviewing their business model.

Email Archiving dengan MailArchiva

paulus — Wed, 13 Aug 2008 08:49:29 +0000

Beberapa waktu lalu bos saya nanya-nanya tentang arsip e-mail beberapa bulan lalu. Cek mail server, tak ada arsip, bo. Lantas beliau minta saya setup arsip mail server di kantor. Secara mail server di kantor pakai ubuntu, solusinya adalah mail-archive gratisan. sebenarnya (mungkin) bisa simpan seluruh email yang masuk dan keluar dengan postfix, mail-server yang saya pakai, tapi karena lagi pengen utak-atik, saya cari solusi tersendiri. Browsing sana sini, sampailah saya ke mailarchiva. Ada dua versi, enterprise edition dan open-source edition. Karena saya tak mau bayar, ya pakai yang gratisan saja. Saya pun download mailarchiva open-source edition.

Setelah download, selanjutnya adalah instalasi.

Ekstrak file hasil download dan jalankan skrip instalasi

tar -xzvf mailarchiva_opensource_edition_server_v1_7_0_linux.tar.gz cd mailarchiva_dist sudo install.sh

Installer akan minta beberapa data untuk lisensi open-source-nya, nama perusahaan, jumlah mailbox, dsb

Start mailarchiva

sudo /etc/init.d/mailarchiva start

Coba login ke mailarchiva

Secara default, mailarchiva akan listen di post 8090. Untuk login ke web interface-nya, masuk ke http://server:8090/mailarchiva. Defaultnya username dan password-nya kosong, nanti bisa dikonfigurasi. Anda juga perlu setup volume baru untuk tempat arsip penyimpanan email (bisa dibuat di satu direktori existing file system, atau di satu partisi baru) serta setup local domain.

Konfigurasi postfix

Tinggal tambahkan baris-baris berikut di file main.cf
milter_default-action = tempfail smtpd_milters = inet:127.0.0.1:8092

Lalu restart postfix.

Selanjutnya, tinggal main-main deh

What’s on your Ubuntu ??

paulus — Thu, 15 May 2008 06:30:11 +0000

So, what’s on your Ubuntu? Here’s my pick after upgrading to the latest 8.04 ubuntu release.

Firefox browser with DownThemAll, AdBlock Plus, UnPlug, and ScribeFire plugin
Thunderbird Mail Client with Enigmail add-on
OpenOffice office suite
Dolphin File Manager (I prefer KDE’s file manager than Ubuntu’s default Nautilus)
Amarok Media Player (again, prefer this KDE apps than Rhythmbox)
VMWare Server Console (this one gave me a hard time)
KeePassX Password Manager
TrueCrypt Disk Encryption

Ubuntu rocks !!!
