MySql Tuning
Untuk memperoleh hasil maksimal dari query terhadap MySQL sebaiknya memperhatikan setting variable pada file /etc/my.cnf
Berikut contoh setting nya
[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
# maksimal koneksi yang diperbolehkan terhadap database
# perhatikan juga setting terhadap httpd.conf yang berkaitan dengan setting
# jumlah klien yang diperbolehkan mengakses
max_connections = 100
skip-locking
skip-innodb
# bila menggunakan versi 4.1x ke atas, terdapat fitur cache terhadap query
# tetapi bila table terlalu cepat berubah, sebaiknya ditiadakan
# karena justru akan membuat lambat query itu sendiri.
query_cache_type= 1
query_cache_limit= 1M
query_cache_size= 32M
interactive_timeout=100
wait_timeout=15
connect_timeout=10
table_cache=128
thread_cache=32
key_buffer=32M
[mysqldump]
quick
max_allowed_packet=16M

KDE : Dolphin as default File Manager
Kenal dolphin kan ? itu lo File Manager bawaan KDE. Emang si sebenere di KDE sebelum versi 4.0, default FIle Managernya menggunakan KONQUEROR. Nah, sekarang ini ada tip dan trik buat nge-default in si Dolphin agar menjadi File Manager default di KDE versi 3.5.x, ini dilakukan di distro yang default instalasi nya menggunakan KDE sebagai Desktop Managernya, seperti distro PCLINUXOS, MANDRIVA, SLACKWARE, dll.
Langsung saja (ini di MANDRIVA, distro lainnya menyesuaikan saja)
- syarat utama, udah ada KDE, trus install dolphin
urpmi dolphin
- masuk ke menu
Star > Tools > System Tools > KDE Control Center
atau
Star > Run Command … isi dengan ¨kcontrol¨
- konfigurasi default file managernya
pilih ¨KDE Componets¨ (di Panel sebelah kiri), trus ¨File Assosiations¨, trus “inode”, trus ¨directory¨ (dibagian tengah)
kemudian di bagian kanan liat ¨Application Preference Order¨, kemudian pilih ¨Add¨, trus klik menu “Tools > System Tools > Dolphin” > klik OK kalo sudah.
Gitu aja, gambar contoh silahkan lihat
Mandriva Spring : Freeradius Simple
Langsung aja (Udah nyambung ke Repo)
$ urpmi freeradius
(tekan Y atau Enter, kemudian tunggu proses instalasi default nya)
Salin file /etc/pki/tls/certs/radiusd.pem dan /etc/pki/tls/private/radiusd.pem menjadi /etc/pki/tls/certs/freeradius.pem dan /etc/pki/tls/private/freeradius.pem. (O iya jangan lupa liat permission file nya) Kemudian edit file /etc/raddb/users, tambahkan (contoh) baris ini di bagian paling akhir.
bayu Cleartext-Password := "halo"
Trus test freeradius dengan mode DEBUG dengan perintah
$ radiusd -X
Buka terminal konsole baru, lakukan test freeradius dengan perintah
$ radtest bayu halo localhost 0 testing123
Hasilnya
radtest bayu halo localhost 0 testing123
Sending Access-Request of id 9 to 127.0.0.1 port 1812
User-Name = “bayu”
User-Password = “halo”
NAS-IP-Address = 127.0.0.1
NAS-Port = 0
rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=9, length=20
Nikto
Description
Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 3500 potentially dangerous files/CGIs, versions on over 900 servers, and version specific problems on over 250 servers. Scan items and plugins are frequently updated and can be automatically updated (if desired).
Nikto is not designed as an overly stealthy tool. It will test a web server in the shortest timespan possible, and it’s fairly obvious in log files. However, there is support for LibWhisker’s anti-IDS methods in case you want to give it a try (or test your IDS system).
Not every check is a security problem, though most are. There are some items that are “info only” type checks that look for items that may not have a security flaw, but the webmaster or security engineer may not know are present on the server. These items are usually marked appropriately in the information printed. There are also some checks for unknown items which have been seen scanned for in log files.
Version 2
Nikto version 2 contains many enhancements over the first version. Some of the major new features include:
Fingerprinting web servers via favicon.ico files
404 checking for each file type

Top Ten Distroś Linux
The bewildering choice and the ever increasing number of Linux distributions can be confusing for those who are new to Linux. This is why this page was created. It lists 10 Linux distributions (plus an honourable mention of FreeBSD, by far the most popular of all of the BSDs), which are generally considered as most widely-used by Linux users around the world. There are no figures to back it up and there are many other distributions that might suit your particular purpose better, but as a general rule, all of these are popular and have very active forums or mailing lists where you can ask questions if you get stuck. Ubuntu, PCLinuxOS and MEPIS Linux are considered the easiest for new users who want to get productive in Linux as soon as possible without having to master all its complexities. On the other end of the spectrum, Slackware Linux, Gentoo Linux and FreeBSD are more advanced distributions that require plenty of learning before they can be used effectively. openSUSE, Fedora, Debian GNU/Linux and Mandriva Linux can be classified as good “middle-road” distributions. KNOPPIX is a live CD (or live DVD); originally very popular as a testing and demonstration tool, although nowadays most major distributions offer a live CD/DVD edition of their products as well. These distributions are loosely listed in order of popularity on DistroWatch, which is NOT an indication of their market share or quality. from http://distrowatch.com/dwres.php?resource=major resume :
