WEB HOSTING- TIPS AND TRICKS

admin — Mon, 19 May 2008 22:38:31 +0000

Webmaster always looks for web hoting sites which is hassle free , fulfills his requirements and which gives full control over the website. almost most of the webmaster had very bad experience with their web hosting site. when looking for cheap and good web hosting , its very trick and require technical skills. some times cheap hosting leads to lots of problem like server down or low bandwidth.

as a site owner , i always looks for website which gives me good information about web hosting and web hosting sites. read through many article on this site , its help me lot to select nice and good web hosting site with affordable price. this site save my lots of time

testimonials from exiting customer and also bad experience from customer also helps a lot , when selecting a good web hosting. bandwidth and disk space is also very impotent factor for good web hosting site.

When you set up an account with the new hosting company tell them that you don’t want the domain name transferred until you tell them so.

Now it is time to do some testing. To make sure that the upload went well and that everything is working after the domain name transfer takes place test a few key pages. You will have to enter the URLs of the pages yourself. This you can do by replacing the IP address with what your hosting company assigned you and the HTML file names with the actual names of the files on your server.

When people look around before choosing a web hosting service it seems like everyone is offering the best and making a choice can be exceedingly difficult. Every hosting service seems to promise the best service for the most competent price. The challenge herein lies in separating the truth from the tall claims and this can be quite an ordeal. Reliability is the most highly priced quality in hosting services and also the rarest.

There is no certain way to do this. Almost every web hosting service promises that a site will be available at least 99 % of the time but in almost all cases this is not true. Most hosting services have a server crash or shut down for maintenance quite often and during this time there is almost no customer service in place either. Many hosting companies go as far as to get a certification from a third party that they are uptime at least 99% of the time in order to get your custom.

linux web hosting is very reliable service, working on linux i learned so much and about linux is that security is prime concern for linux server.
i read many article on linux-web-hosting , and i think reading helps me lot. as a learner and a user of linux web hosting i always looking for those web hosting site which provide all the requirement i`m looking for. if you looks for advantage with linux based web hosting , its gives the enrichment and power of php programing. since Linux is extremely compatible with the PHP programming language that is gaining popularity these days. the of the advantages of linux os is that it is open source and free of cost most of the versions. he cost involved is also a factor that is attracting a lot of developers these days. The fact that these operating systems are mostly available for free makes it really economical. Thus, customers can get some additional software’s that are required for Linux platforms. Some of these software’s are Apache, BIND, Sendmail and APF Firewall.

Nmap Command

admin — Mon, 19 May 2008 14:44:15 +0000

Again here’s a reminder about the nmap command. I needed the command to what was a udp port or a tcp port. To test a listening UDP port, simply use nmap as nmap -p [port] -sU -P0 [host name | ip address]

# nmap -p 123 -sU -P0 nmap -p 123 -sU -P0 123.123.123.123

An example of the output from the command

# nmap -p 4000 -sU -P0 localhost

Starting nmap 3.70 ( http://www.insecure.org/nmap/ ) at 2008-05-20 11:00 EST
Interesting ports on localhost (127.0.0.1):
PORT STATE SERVICE
4000/udp closed icq

Nmap run completed — 1 IP address (1 host up) scanned in 0.057 seconds

Repository Unofficial Joomla

Ini merupakan tulisan pertama saya, dalam kurun waktu yg cukup lama setelah domain ini up kembali dan tewas’a hosting di blog saya yg lain. Saya tidak begitu tau pasti kenapa tempat hosting’a, namun saya memaklumi’a karena tempat hosting tersebut merupakan salah satu dari sekian banyak tempat hosting yg menyediakan space 200Mb secara gratis yang sudah lumayan banyak di internet bila Anda mau mencari’a (hehehe…), sebagai tulisan perdana maka saya hanya menuliskan cara mudah meng-instal Joomla dari paket Debian, paket Joomla untuk Debian ini di paketkan ke Debian oleh mbak Nur Aini Rakhmawati, yg saat ini juga tergabung di Wanita Debian Indonesia dan juga telah masuk ke daftar Developer Joomla International, sudah cukup banyak partisipasi’a dalam dunia persilatan opensource, dan dia merupakan wanita indonesia pecinta Debian yg saya kenal dari kunjungan kenegaraan ke taiwan dikala itu (cie…cie…), sehingga saya memberikan sedikit usaha untuk menyebar luaskan paket ini kesegala penjuru dunia walau dengan memanfaatkan posisi saya sebagai tim repository untuk tanah kelahiran saya di Nanggoe Aceh Darussalam. Saya rasa ini lebih baik dari pada berkoar-koar layak’a ayam kesurupan tidak menentu tanpa menberikan apapun kepada masyarakat free software yg telah menanamkan rasa untuk saling berbagi dan berkontribusi dalam ilmu pengetahuan yg tidak dapat di bayar dengan uang merah ribuan (seperti lirik lagu slank saja huehuehue…). baiklah…dari pada saya menuliskan kata-kata yg dapat menimbulkan perang saudara dan membanjiri kolom komentar di blog ini maka kita mulai saja langkah-langkahnya….

Apabila rekan-rekan ingin menggunakan repository tidak resmi dari joomla, maka tambahkan entry berikut ke /etc/apt/sources.list :

AcidRip DVD Ripper

ripping and encoding DVD tool using mplayer and mencoder
AcidRip is a Gtk::Perl application for ripping and encoding DVD’s. It neatly wraps MPlayer and MEncoder, which I think is pretty handy, seeing as MPlayer is by far the best bit of video playing kit around for Linux. As well as creating a simple Graphical Interface for those scared of getting down and dirty with MEncoders command line interface, It also automates the process in a number of ways:

Bind /etc/named.conf Missing

admin — Mon, 19 May 2008 03:41:46 +0000

i was trying to install bind dns server with my centos 5 and i couldnt locate the /etc/named.conf

i tried installing using

yum install bind-chroot bind*
and looks like there is often a problem with bind installed through yum. when i tried to restart the named daemon i am getting failed.
Locating //etc/named.conf: [FAILED]

This is a bug on centos 5 saying that no longer /etc/named.conf bundled. see this

How to Fix:

If you have installed bind-chroot, then it uses default configuration file instead of

if you have used yum with yum install bind, then /etc/named.conf should be probably missing. so while installing bind with centos 5 use yum install bind-chroot

Installing Ubuntu With A Software RAID1 Configuration

admin — Mon, 19 May 2008 01:43:31 +0000

In this post I will be showing you how you can install a fresh copy of Ubuntu on a server using two Hard disk drives either ATA or SATA drives, I would recommend using proper server hardware as if one of the HDD controllers fail then you still wont be able to reboot your server immediately. For thoses who are not familiar RAID1 mirrors data identically over two (or more) hard disks.

1. Firstly enter your Ubuntu Server Compact disk into the CD-ROM tray and boot the server with it, When you get to the Partioning options menu you will need to select ‘Manual’ like shown below:

2. Next I created 3 partitions on both disks: 8 GB for /, 500 MB for swap and the remaining space for /home. Please note that at this stage the partition types must be “physical volume for RAID” (0xFD in fdisk) instead of “Ext3 journaling file system”. Also note how the first partitions of both disks are marked bootable (the B flag in picture 4). Without setting those partitions bootable you might not be able to boot your computer without a CD!

3. Setting partition type and bootable flag, Next I went up and selected “Configure software RAID” (picture 4).

4.Two disks with partitions for RAID1 volumes, Next I saved the modifications made to the partition tables (picture 5).

5. Saving the changes, Next I created three (3) MD devices (each configured as RAID1 with 2 active and 0 hotspace disks — pictures 6-9).

6. Creating new MD devices.

7. RAID1 = mirror.

8. Two active devices.

9. No spare devices, Next I selected the physical disk partitions to be included in the RAID1 set (picture 10). It’s important to select two partitions with identical sizes so in my case md0=sda1+sbd1, md1=sda2+sdb2 and md2=sda3+sdb3.

10. Selecting MD components, Next I configured file systems and mount points for each RAID device. In my case “RAID device #0″ is ext3 mounted on /, “RAID device #1″ is swap and “RAID device #2″ is ext3 mounted on /home (pictures 11-15).

11. File systems created on the RAID devices.

12. / filesystem created on the RAID device #0

13. swap created on the RAID device #1

14. /home filesystem created on the RAID device #2

15. All file systems configured, Finally I went down and selected “Done setting up the partitions” and selected “Yes” to write the changes made to the partition table (picture 16). From this point on the Ubuntu installation is a normal installation.

16. Saving the changes.

After installation and the first reboot I installed grub also on the second disk’s (/dev/sdb) master boot record (MBR). Without this the PC will not start if the first disk (/dev/sda) fails and is removed from the PC.

sudo grub-install sudo grubgrub> device (hd0) /dev/sdbgrub> root (hd0,0)grub> setup (hd0)grub> quit

There is a serious bug in Ubuntu 7.10 (see this and this for details) which makes the boot fail if one of the physical disks in the RAID1 set is missing.

Testing it out..

After installation I verified that all file systems (/, swap and /home) are really on the RAID1 disks.

grep /dev/md /etc/fstab/dev/md0 / ext3 defaults,errors=remount-ro 0 1/dev/md2 /home ext3 defaults 0 2/dev/md1 none swap sw 0 0martti@ubuntu:~$ df -h / /homeFilesystem Size Used Avail Use% Mounted on/dev/md0 7.4G 586M 6.4G 9% //dev/md2 12G 159M 12G 2% /home

The status of all RAID devices can be checked from the /proc/mdstat file. Each mdN device contains two sdXN disks and each mdN device should have “2/2″ and “UU”. More details can be seen with the mdadm utility.

cat : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]md2 : active raid1 sda3[0] sdb3[1] 12659136 blocks [2/2] [UU]md1 : active raid1 sda2[0] sdb2[1] 489856 blocks [2/2] [UU]md0 : active raid1 sda1[0] sdb1[1] 7815488 blocks [2/2] [UU]unused devices: martti@ubuntu:~$ sudo mdadm –query –detail /dev/md0/dev/md0: Version : 00.90.03 Creation Time : Wed Oct 17 16:45:59 2007 Raid Level : raid1 Array Size : 7815488 (7.45 GiB 8.00 GB) Used Dev Size : 7815488 (7.45 GiB 8.00 GB) Raid Devices : 2 Total Devices : 2Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Wed Oct 17 15:16:18 2007 State : active Active Devices : 2Working Devices : 2 Failed Devices : 0 Spare Devices : 0 UUID : Events : 0.11 Number Major Minor RaidDevice State 0 8 1 0 active sync /dev/sda1 1 8 17 1 active sync /dev/sdb1

Recovering from a failed disk..

Next I simulated a disk failure by disconnecting /dev/sdb. The system still boots but the status shows /dev/sdb1, /dev/sdb2 and /dev/sdb3 have disappeared from the system and how the /dev/mdN is marked as “degraded” in the status field.

cat : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]md2 : active raid1 sda3[0] 12659136 blocks [2/2] [U_]md1 : active raid1 sda2[0] 489856 blocks [2/2] [U_]md0 : active raid1 sda1[0] 7815488 blocks [2/2] [U_]unused devices: martti@ubuntu:~$ sudo mdadm –query –detail /dev/md0/dev/md0: Version : 00.90.03 Creation Time : Wed Oct 17 16:45:59 2007 Raid Level : raid1 Array Size : 7815488 (7.45 GiB 8.00 GB) Used Dev Size : 7815488 (7.45 GiB 8.00 GB) Raid Devices : 2 Total Devices : 1Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Wed Oct 17 15:16:18 2007 State : active, degraded Active Devices : 1Working Devices : 1 Failed Devices : 0 Spare Devices : 0 UUID : Events : 0.11 Number Major Minor RaidDevice State 0 8 1 0 active sync /dev/sda1 1 0 0 - removed

Next I reconnected the disk and instructed the system to rebuild itself. After rebuild everything was ok again.
