Software Freedom Day Event at BL

Yesterday, We (me & mywife) were attending the ceremony of Software Freedom days at Budi Luhur University, and like any other years before, this year, echo also invited to be one of a speaker. As far As I know, this is the third time echo colaborate with Budi Luhur Linux User Group to celebrate the event.

Hero, one of echo staff is talking about wireless, focusing on how to create a cheaper internet connection, based on wireless ( also share howto create the famous cantenna or wajan-bolic antenna ), az001 also give some (very) short demo penetration to one of  BudiLuhur sites before the event was close, although we promise nothing would be harmed and everything patched after that. Last year echo also giving a speech in this event, and we will always support this kind of events.

Software Freedom Day (SFD) is a worldwide celebration of Free and Open Source Software (FOSS). The goal in this celebration is to educate the worldwide public about of the benefits of using high quality FOSS in education, in government, at home, and in business -- in short, everywhere! http://softwarefreedomday.org/about

Freedom. The English word "free" is ambiguous. Here's how Richard Stallman disambiguates the term:

"Free software" is a matter of liberty, not price. To understand the concept, you should think of "free" as in "free speech," not as in "free beer."

Software Freedom Day was established in 2004 and was first observed on August 28, 2004 when over 70 teams participated. Since that time it has grown in popularity as more than 300 teams from over 60 countries celebrated on the second SFD, held on September 10, 2005. The primary sponsor for 2005-2006 was Canonical Ltd., the company behind Ubuntu, a GNU/Linux distribution. From 2006 onwards, it has been decided the Software Freedom Day to be held on the third Saturday of each September: 15 September 2007,20 September 2008, etc. - taken from wikipedia.org

Hope to see you all on next SFD events :)

Firefox slow scroll on intel

venom ~ # lspci -v | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller])

Aku temukan ini cukup mengganggu dan mengurangi kenikmatan dalam melakukan scrolling di firefox/adobe acrobat reader, dsb, setelah googling sana-sini aku temukan bahwa driver milik intel untuk Gentoo (kemungkinan distro lain dnegan driver yang sama) yaitu xf86-video-i810-2.2.1 harus ditambahkan instruksi secara manual. jadi buka file xorg.conf milikmu dan tambahkan di Section "Device"

Option "AccelMethod" "XAA"
Option "XAANoOffscreenPixmaps" "true"

, Seharusnya XAA (XFree86 Acceleration Architecture) arsitektur sudah digantikan oleh EXA, tetapi driver milik Intel belumlah mengimplementasikan EXA saat ini, jadi satu-satunya cara adalah mengkonfigurasikan diver tersebut untuk menggunakan arsitektur XAA.

Vmware tips on GNU/LInux

Vmware tips on gentoo or other linux ditribution that facing same problems,

1. Running vmware images installed on ntfs partition

problem details : #843863, and how to solve it:
#vi vmware.vmx files
and append mainMem.useNamedFile="FALSE"

2. Shift (and other keys) arent working after vmware running
for details, see 195982

And the temporary fix is to set the keyboard mapping after youve "full screen" the Vmware console, open your terminal and, (*type*)
$setxkbmap

Thats all, hope it helps :)

Gentoo glibc update

At last, the Gentoo toolchain guys create a patchset for this bug. Yeah at least for a couple of month i cant use wvdial to be my internet dialer (that it use to be). Its silly , because all the patch that ive use (someone inform that the patch work, also i managed to develop one that should be working also) arent working.

Because of this problem, im using pon and poff scripts as a dialer, even its not so bad (yeah, it hide our password tough), but its function so limited and configuring it made some of us miserable (so i prefer wvdial with that (editable) one file configuration :P) . The glibc-2.8_p20080602 are release yesterday also with a bunch of patchset.

!Go patch your glibc :), kudos to vapier (the toolchain guys) for making this up :P ...

Tunning Gentoo; hardcore series

Berikut adalah inti dari diskusi gw dengan the_hydra (thx man :P) seharian ini (wekz, ketauan dah kalo kerjanya chatting :P), permasalahan ini gw rasakan sejak gw menggunakan kernel baru dan environtment baru di gentoo gw (2008.0 beta 2 upgradble version). Permasalahannya adalah jeleknya manajemen memori dan kerja prosesor yang gw rasakan dan akhirnya kita troubleshoot bareng, dan karena ini satu-satunya salah satu dari chat gw yang berkualitas maka detilnya bisa di baca disini (di publish atas seijin the-hydra)

Adapun intinya adalah gw memodifikasi parameter kernel gw, dengan menambahkan entry dibawah ini ke /etc/sysctl.conf (penjelasan tiap paramater harap dicari sendiri) dan ingat ini adalah konfigurasi untu komputer lenovo R60 dengan kernel 2.6.25-gentoo-r4 #1 SMP (dan jangan berharap hasil yang sama untuk mesin dengan arsitektur dan kernel versi lain)

vi /etc/sysctl.conf
#im tunning the VM
vm.swappiness = 20
vm.overcommit_memory = 1
vm.laptop_mode = 1

kemudian permasalahan memori selesai (bisa menggunakan "cat /proc/meminfo", "top" atau "free -m" untuk melakukan pemeriksaan), lalu berlanjut kepermasalahan penggunaan prosessor oleh user/process yang berujung kepada limitasi proses untuk user (sepertinya hal ini perlu saya diskusikan di milis resmi gentoo, tapi nanti dah) yang setelah di lihat "unlimited" dibandingkan dengan default set pada debian/ubuntu

untuk gentoo

core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 16237
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) unlimited
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited

sedang debian/ubuntu

core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 16379
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 16379
virtual memory (kbytes, -v)
unlimited file locks (-x) unlimited

sehingga saya harus melakukan setting "echo ulimit -u 16237 > .bashrc" untuk tiap user (Sedikit ada human error saat melakukan ujicoba pada user root yang sudah di limit dengan user biasa dan terlambat untuk disadari).

Selanjutnya checking kernel configuration juga di lakukan serta terakhir melakukan compiling ulang untuk menyalakan PREEMPT (ingat, bukan PREEMPT_VOLUNTARY), kemudian mengkompile ulang, 3 langkah tersebut sudah cukup ampuh (untuk saat ini) menangani kemungkinan DOS akibat user/aplikasi.

ok enjoy(tm) .. sampai jumpa di chat berkualitas lainnya :P

Akhirnya Datang Juga ..

Yup, ternyata pesanan waktu itu (baca juga :ubuntu-804-coming-soon) dikabulkan juga :), seharusnya sudah di terima dari 10 hari yang lalu, tetapi karena baru hari ini mampir ke markas (kantor) setelah merantau di negara lain, maka hari ini barulah ini cd diterima. Dan beruntunglah uang bea lalu bea sebesar 3000 rupiah dibayarkan dahulu oleh mbak-mbak resepsionis (hehehhee, terima kasih mbak). Walaupun belum yakin akan bisa mencoba hardy ini secepat mungkin (secara venom sudah ber-os-kan Gentoo, sedangkan tarantula yang ber-os-kan Gutsy Gibbon sedang sakit keras (jika tidak maka seharusnya akan di upgrade ke Hardy)), tetapi setidaknya sudah punya CD Originalnya, kqkqkqkkq.

*mode: hunting PC nganggur buat di installin hardy*

Gentoo Wvdial, Segmentation Fault

Ive found this error (segmentation fault, hmm.. sound interesting :P) when using wvdial to connect to the internet (which never happen before i upgrading my machine)..

AT+CGDCONT=1,"IP","indosatgprs"

Segmentation fault.

After googling and hunting, ive found out that some people has a same problem with me, and also at the right place to check about gentoo bugs (206579) also the patch that ive already use 218504 and the one that i develop arent working :(.

Ive already patch the wvstream, using this patch (carefull in using the patch, u have to put it in ebuild, because if u dont do so then after u re-emerge, the patch wont work) and rebuild wvdial, wvstreams, ppp, glibc and gcc (some friends said this is a bug in gentoo's glibc package, but the toolchain guys still not responding about it). So, now im still using pon (pppconfig) to connect to internet using my Claymore.

Somebody could help? :)

Ubuntu 8.04: coming soon

using the countdown image, get it here

Three Days To go!

- Request your cd
- Download a cd

and here is my request



.. just wait n try :)

gentoo-synce with my xcalibur

Yeah, At last! it never work on fedora, ubuntu and other distros that i ever use ( or it because i never do compiling (try) to install it on some other distros (no need to ?)) but with this instruction and some luck, now my XDA got detected and sync with my gentoo using SyncE

FYI, the instruction; u need to build a python module and python-setuptools first (our you would find a hard time with one-by-one install it later).. carefull, u have to do some kernel re-compile, dbus modification (installation) and other thrilling thing, but no problem .. its gentoo anyway(GNU/linux)!



please check the interface (rndis0) and ping it, now you are ready to do ICS, or whatever :d (installing some daemon on xcalibur ?)



Beatiful isnt it ? hshh

Gentoo 2008.0_beta1 unleashed

Donnie Berkholz, Posted about 2008.0_beta1 unleashed on April 1, 2008 at gentoo homesite (gentoo.org)

When we said "soon," even we didn't realize how soon it would be. 2008.0_beta1 is here. Your support and enthusiasm are greatly appreciated—thank you.

You can help make 2008.0 amazing! Test out this beta and report any functionality issues you encounter. Since this is the first beta, we're looking only for bugs in functionality, not bugs in appearance such as desktop backgrounds or other artwork. We expect to release a second beta once your testing has helped us fix problems with this first beta.

A migration to RPM was carefully considered again for this release, but in the end we decided to wait for the few remaining RPM-using distributions to migrate to the superior packaging format of ebuilds.

Download this Gentoo beta1:

Gentoo 2008.0_beta1 Minimal CD/InstallCD
(up to 130 megabytes depending on arch)
alpha | amd64 | hppa | ia64 | ppc64 | sparc64 | x86

Gentoo 2008.0_beta1 Universal install CD
(up to 600 megabytes depending on arch)
ppc64 | sparc64

Gentoo 2008.0_beta1 LiveCD
(up to 700 megabytes depending on arch)
i686 | amd64 | ppc64 (32-ul)

Gentoo 2008.0_beta1 LiveDVD
i686 (3.8G) | amd64 (1.6G)

Thats why, when i do some sync (emerg --sync), and check the update package (emerge -pv world) then i found out that i have to download almost 850 MB of new package (ive already updated openoffice, n some important tools for me (such as truecrypt, nmap, madwifi, wireshark and else)), and now the update process are still on progress ... pyuhh



so, go get gentoo new version ! m000...

Debian, Guided partitioning, update kernel

Im using Debian 4.0 codename Etch for one of our server and during the installation process (partitioning disk) i choose Guided - use entire disk and choose Separate /home, /usr, /var, and /tmp partitions for Partitioning scheme (hell yeah , im so lazy to slice it manually) in the next step and change the file system to XFS.



then it gives me 262M for / with XFS filesystem.And when i upgraded the default kernel (avoided vmslice bug) the system refuse to install new kernel, and give me an error

failed in buffer_write(fd) (9, ret=-1): backend dpkg-deb during `./lib/modules/2.6.18-6-686/kernel/sound/core/seq/instr/snd-ainstr-iw.ko': No space left on device
dpkg-deb: subprocess paste killed by signal (Broken pipe)

Yup, it inform that i dont have more spaces for the new kernel (darn, the guided things only prepare space for one kernel), some trick to resolve this problem is giving more space for the kernel (/lib/modules)

#mv /lib/modules /var/libx/lib/modules ;or any place u like
#ln -s /lib/modules /var/libx/lib/modules/

Warning !!! : Dont try to symbolic links the /lib for your own good and in any case you do so, the easy way is using another live cd to mount your linux and move back the /lib

enjoy(tm) dont be lazy .. and be safe!!

Backup ..

This is an old (8th years already) sh script for backup your linux machine, Using TAR for doing a full backup and daily incremental backup, yup still the best for me :)

#!/bin/sh
# full and incremental backup script
# created 07 February 2000
# Based on a script by Daniel O'Callaghan
# and modified by Gerhard Mourani

#Change the 5 variables below to fit your computer/backup

COMPUTER=venom # name of this computer
DIRECTORIES="/home/ammar/" # directoris to backup
BACKUPDIR=/media/backup # where to store the backups
TIMEDIR=/media/backup/last-full # where to store time of full backup
TAR=/bin/tar # name and locaction of tar

PATH=/usr/local/bin:/usr/bin:/bin
DOW=`date +%a` # Day of the week e.g. Mon
DOM=`date +%d` # Date of the Month e.g. 27
DM=`date +%d%b` # Date and Month e.g. 27Sep

if [ $DOM = "01" ]; then
NEWER=""
$TAR $NEWER -cfz $BACKUPDIR/$COMPUTER-$DM.tar.gz $DIRECTORIES
fi

if [ $DOW = "Sun" ]; then
NEWER=""
NOW=`date +%d-%b`

# Update full backup date
echo $NOW > $TIMEDIR/$COMPUTER-full-date
$TAR $NEWER -cfz $BACKUPDIR/$COMPUTER-$DOW.tar.gz $DIRECTORIES

else

# Get date of last full backup
NEWER="--newer `cat $TIMEDIR/$COMPUTER-full-date`"
$TAR $NEWER -cfz $BACKUPDIR/$COMPUTER-$DOW.tar.gz $DIRECTORIES
fi

Combining it with crontab and see how powerfull it is :)

Gentoo, Nessus 3.0.6 and .ebuild

I never try nessus on gentoo (last time i check :P, im using it under ubuntu), i just emerge it before and never run it. Yesterday, when i was trying to run nessus, ive found that it suck all my CPU, the process are so slow even my cursor are in slow motion :D, even for loging in my nessus-client to the localhost nessus server. The unbelieveable part was the "top" output from my gentoo, it suck my CPU 101%, wtf..




so i check the nessus version that im running, im still running nessus version 2.2.6, which is reported still has a bug on it not only in memory handling but it cant be use to scan et all (blah...) , so i decide to remove it (unmerge) and then install the fancy "nessus-client" version 1.0.2 and nessus-bin version 3.0.5 (as its listed on emerge --search). FYI, Gentoo using suse package (sad, they dont make it for gentoo, hell yeah.. who cares :P) then converted it using the rpm, but the problem is when i try to emerge nessus-bin, the nessus already updated to newer version, which is 3.0.6 and the ebuild are for nessus version 3.0.5, with a little effort i figure out how to make this new version works on your gentoo. follow this step to hack the ebuild files and successfuly install the nessus

1. grab a copy of newer nessus, im using suse version > Nessus-3.0.6-suse10.0.i586.rpm
and put it on /usr/portage/distfiles

2. i need to make a symbolic link some library, because it still using the lower version (mine is newer), u can pass this step if your libssl and libcrypto already 0.9.7 version.
sudo ln -s /usr/lib/libssl.so.0.9.8 /usr/lib/libssl.so.0.9.7
sudo ln -s /usr/lib/libcrypto.so.0.9.8 /usr/lib/libcrypto.so.0.9.7

3. edit your nessus-bin ebuild at /usr/portage/net-analyzer/nessus-bin
change the ebuild name from nessus-bin-3.0.5.ebuild to nessus-bin-3.0.6.ebuild
and tweak some part of the header, also the Manifest files (modify the signature)
for an easy way , ive already created the ebuild for nessus-bin version 3.0.6 , you all can grab it here. extract and copy all the folder under directory /usr/portage/net-analyzer/

4. Final step, just do the magic command "emerge nessus-bin" and you will get a nessus-bin 3.0.6



thats all folk, enjoy your nessus! Be Safe :)

Gentoo SonyEricsson USB Cable DCU-11 driver

Maybe in some distro, the module are automatically loaded, but not in gentoo, I found it when i try to connect my old sony ericcson k500i using DCU11, its been a long time im not using it (and never use it with gentoo), so when i plug the cable n nothing happens :). So, if u found a problem with the DCU 11 Usb cable, so u may need this some short and not l33t instruction :)

After You plug-in the usb cable, and you find out that your driver was unknown, by seeing it from dmesg output

localhost tty# dmesg | grep usb

--- truncated ---

usb 4-1: USB disconnect, address 2

usb 4-1: new full speed USB device using uhci_hcd and address 3

usb 4-1: configuration #1 chosen from 1 choice

Then, check whether the module is loaded by the kernel. If not, then weve found the cure :)

localhost tty # cat /usr/src/linux/.config | grep CONFIG_USB_SERIAL
---truncated --
CONFIG_USB_SERIAL_NAVMAN=m

# CONFIG_USB_SERIAL_PL2303 is not set
# CONFIG_USB_SERIAL_HP4X is not set

--- truncated ---

Now, you need to re-compile your kernel, u can do it manually or using genkernel
to compile it for you, what u need to do is activate the module, so it can be loaded
by the kernel. Use make menuconfig commands, or genkernel --menuconfig all

Device Drivers --->
USB Support --->
---- USB Serial Converter support ----->
[M] USB prolific 2303 Single Port Serial Driver

Then re-compile it, after that u can check the dmesg output again, make sure to use the new kernel :)

localhost ~ # dmesg | grep usb

---truncated--
usbcore: registered new interface driver pl2303

drivers/usb/serial/pl2303.c: Prolific PL2303 USB to serial adaptor driver

usbcore: registered new interface driver hci_usb

usb 4-1: USB disconnect, address 2

usb 4-1: new full speed USB device using uhci_hcd and address 3

usb 4-1: configuration #1 chosen from 1 choice

usb 4-1: pl2303 converter now attached to ttyUSB0
--truncated---

there u go, now just use /dev/ttyUSB0.
thats all folk, hope it helps

Beberapa Tips untuk Gentoo di lenovo R60

installing JRE/eric problems

Kalo kamu menemukan masalah untuk menginstall JRE, ERIC dsb setelah kamu melakukan update packet menggunakan portage dan mengakibatkan versi gcc kamu terupgrade ke versi 4.x.x, sementara beberapa aplikasi yang akan kamu install masih membutuhkan GCC versi 3.x.x,

silahkan coba ini:

Code:
# echo "=sys-devel/gcc-3.3*" >> /etc/portage/package.mask
# emerge virtual/libstdc++

dengan menginstall paket emerge virtual/libstdc++ akan menginstall libstdc++-v3 yang di butuhkan

installing VLC
Sedikit tricky untuk melakukan installasi VLC pada gentoo, terutama apabila hanya meng-emerge vlc saja. Agar VLC anda berjalan dengan sempurna maka anda perlu menambahkan paket lain yang "terkait" dan digunakan oleh VLC ke /etc/portage/package.use,

echo "media-video/vlc dvd ffmpeg mpeg mad wxwindows aac dts a52 ogg flac theora oggvorbis matroska freetype bidi xv svga gnutls stream vlm httpd cdda vcd cdio live" >> /etc/portage/package.use

lalu install VLC dengan info terkait
#emerge vlc

*mudah-mudahan bermanfaat, ada beberapa tips terkait yang gw lakukan saat menginstall Gentoo 2007-1 ke lenovo r60 tetapi masih berbentuk satu buah file berformat teks yang amburadul. Mudah-mudahan ada waktu buat publish :), masih banyak kasus-kasus yang "tricky" lainnya :)

Log: Gutsy Gibbon

Hari ini, Request CD Gutsy gw dah nyampe ( kayaknya ga pake bayar pos, kali ini.. hmm )

Gutsy Gibbon !

Akhirnya, Gutsy gw bisa 98% berjalan dengan baik setelah menerima kopian Alternate CD Gutsy Gibbon (7.10), dan tinggal menjalankan gksu "sh /media/cdrom/cdromupgrade" dari shell, sebelum itu g harus menginstall aplikasi "ubuntu-desktop" terlebih dahulu karena ternyata aplikasi itu pernah gw uninstall.

Setelah proses upgrade menggunakan cd tersebut maka semua keanehan akibat partial upgrade pun musnah, upgrade bentar via inet trus putus, lalu upgrade lagi, lalu install sangat tidak dianjurkan bagi yang tidak mau repot :P, disamping harus mengunduh 810 MB data. Lakukan Upgrade dari CD alternate, biar aman.

Tetapi kali ini ternyata sound tetap bermasalah (meski sudah merubah konfigurasi alsa-base di /etc/modprobe.d) dan ada laporan perbedaan setting keyboard (bisa di timpa ulang), selebihnya masih berjalan baik. Sekarang mengusahakan agar tarantula bisa bersuara lagi :)

updated: 99,9% sudah berfungsi baik sampai tombol hotkey milik toshiba lihat komentar untuk sedikit solusi

Gutsy Journey

Masih berlanjut dengan edisi "dist-upgrade" ke gutsy (yang partial n tidak sekali kelar donlod). Selain masalah driver ATI (yang dah kelar dengan meng-unduh driver ati baru yang berukuran lebih kurang 50 MB (phiew)), serta sound (masih masalah karena tidak ada suara yang keluar, meski tanpa error.. masih progress), gw nemuin 2 masalah sederhana.

1. Soal Auth user gw saat menggunakan "graphical user interface" untuk mengadministrasi OS (misal menjalankan synaptic)

akan muncul error box yang berisikan unable to copy the user's Xauthorization file
untuk mengatasinya cukup dengan mengkonfigurasikan ulang xauth dan men chown file tersebut ke user

root@tarantula:~# dpkg-reconfigure xauth
chown y3dips.y3dips /home/y3dips/.Xauthority

2. Tidak suksesnya melakukan installasi ubuntu-keyring

Setting up ubuntu-keyring (2007.06.11) ...
gpg: symbol lookup error: /usr/local/lib/libreadline.so.5: undefined symbol: BC
gpg: symbol lookup error: /usr/local/lib/libreadline.so.5: undefined symbol: BC

Setting up kernel-package (11.001) ...
Errors were encountered while processing:
ubuntu-keyring
E: Sub-process /usr/bin/dpkg returned an error code (1)

cara untuk mengatasinya adalah menghapus libreadline, kemudian mengkonfigurasikan ulang library tersebut dengan ldconfig

root@tarantula:/usr/local/lib# rm -rf libreadline.*
root@tarantula:/usr/local/lib# ldconfig
root@tarantula:/usr/local/lib# apt-get -f install

Oh iya, aku tidak menggunakan kernel gutsy (kernel 2.6.22-14 ) ,tetapi masih memakai ( 2.6.20-15 ), karena permasalahan saat booting (blank screen?). Mungkin akan di coba kompile dari vannila kernel aja nanti ..
