Software Review: ActiveISO Burner 0 comments

I'm a Linux guy and part of being in-love with Linux involves burning Linux OS. Of course, this OS comes in an ISO format. I don't want to spend a single bucks for a burner software just to burn those iso images.

I've found ActiveISO and it makes the job done. Of course, it is FREE.

The interface is so simple. I don't need a graphical GUI just to burn an iso. Just look for the iso images and Burn Iso button. I usually set the burning speed at 1X. After a couple of minutes, viola! The iso images was now burn to a cd/dvd disc.

You can download ActiveISO here.

BTW, its for Windows only.

My view on Windows 7 0 comments

Here come again Microsoft giving everyone a taste test. After trying Windows 7 since August of 2009, I finally concluded that of all operating system Microsoft did (let me reinstate that again "of all operating system MICROSOFT did"), this one was the best. Its like the combination of Windows Xp's performance and the visual appearance of Windows Vista including the Aero.

I've installed Windows 7 RC Build 7100 to my Acer Aspire 4715Z laptop. It works fine even with a memory of only 1.5GB DDR2 667 (though having a memory of 1GB is the minimum recommended requirements). Bad thing I can't run my favorite online game Special Force (but I believe this only occur in build 7100. Other users who have tried Windows 7's official release has running Special Force). I also like the taskbar app grouping with those cute hover thing.

Definitely this one is not a flop unlike Windows Vista.

My Black E71 0 comments

I just got my new Nokia Black E71. My first impression about this phone is it was just an ordinary Nokia phone. But I realize that a little customization will actually make this phone more productive. I love the shortcuts on the Home Screen plus you change the Mode Settings its like having a 2 Profile Setup. I've installed Facebook, Free I-sms (my favorite sms tool) and Skyfire (my favorite mobile browser). I love also the Calendar features of this phone. You could easily see the schedule by just dragging your pointer on your preferred date. You can also use Nokia PC Suite to transfer files from your computer to your phone, sync contacts to your Outlook Email Client, install symbian apps, upload pics and music files and use Calendar.

The keypad is fine with me. I can press any button with no difficulty (or is it my finger because they are thin?). Also the casing of the phone was stylish. Just make sure you don't drop the phone because it was glossy all scratch can easily be seen.

How to check ReverseDNS 0 comments

I usually setup reverse dns when I setup a mail server. Usually, mail server nowadays verify the ptr record or reverse dns of the ip address so detect if its a legitimate server or just a spammer.

If you have a linux box, jsut do the ff

dig -x or host

Sample output:

224.114.147.69.in-addr.arpa. 1193 IN PTR b1.www.vip.re3.yahoo.com.

Make sure you have installed the dig command.

If you are using Windows, do the ff

nslookup

Sameple output:

C:\Users\Nelson>nslookup 74.125.53.100

Name: pw-in-f100.1e100.net
Address: 74.125.53.100

2 sshd daemon on one machine 0 comments

I have a machine with two nics. I need to setup ssh rules. One with private/public key for the public access and one with no restriction for the private lan access. Assuming that you are using openssh rpm package of your favorite distro.

I decided to put this blog so that people would not spend a lot of time discovering how to setup 2 sshd daemons..

1. cd /etc/ssh
2. cp sshd_config sshd2_config

Edit sshd2_config and change the ff:

PidFile /var/run/sshd2.pid

3. ln -s /usr/sbin/sshd /usr/sbin/sshd2

4. cd /etc/rc.d/init.d/

5. cp sshd sshd2

Edit sshd2 and change the ff:

config: /etc/ssh/sshd2_config
pidfile: /var/run/sshd2.pid
[ -f /etc/sysconfig/sshd2 ] && . /etc/sysconfig/sshd2
prog="sshd2"
SSHD=/usr/sbin/sshd2
PID_FILE=/var/run/sshd2.pid

6. Create a file /etc/sysconfig/sshd2 and put the ff:

OPTIONS="-f /etc/ssh/sshd2"

The new sshd2 init script will try to source a configuration file in /etc/sysconfig/sshd2. In this configuration file we will tell the SSH daemon to start up with a different SSHD configuration file from the default /etc/ssh/sshd_config:

If your system has PAM enabled you will also need to provide a separate PAM configuration file for the new sshd-internal service. To keep things easy we are just going to link to the default sshd configuration file for PAM:

cd /etc/pam.d
ln -s sshd sshd-internal

7. Finally, start sshd2

/etc/init.d/sshd2 start

The advantage of providing a separate sshd2 binary through a symbolic link to the original sshd is that both running SSH daemons will always use the same application version. This is also true after an update of its RPM package for example

Error mount: unknown filesystem type ‘ntfs’ 0 comments

If you trying to mount a ntfs hard drive and encountered the ff error

mount: unknown filesystem type ‘ntfs’

it means your kernel doesn't support ntfs yet. To make you're OS read ntfs, its either compile your kernel with ntfs support or install the ff

fuse
fuse-ntfs-3g
dkms
dkms-fuse

After installing, mount the drive the normal way mount -t ntfs-3g /dev/sda1 /mnt

I'm using Centos 5 and download those rpm available on RedHat EL5 since Centos was a derivative of RHEL5

How to change editor on Crontab 0 comments

I'm a big fan of VIM. I also like VI but I like editor with colors so I'm more fun of VIM.

Crontab use editor and you can specify what editor to use. Default editor was VI but as I said, like VIM more so I decided to use VIM as my editor on cron. To do it, type in your shell

export VISUAL=vim

You can put it in your .bashrc found on your home directory so that whenever you login, you will not command it again.
