Denyhost is a script intended to run by linux system administrators to help thwart SSH server attacks (also known as dictionary based attacks and brute force attacks).

If you’ve ever looked at your ssh log (/var/log/secure on Redhat, /var/log/auth.log on Mandrake, etc…) you may be alarmed to see how many hackers attempted to gain access to your server. Hopefully, none of them were successful (but then again, how would you know?). Wouldn’t it be better to automatically prevent that attacker from continuing to gain entry into your system?

Laptop power off when put mobile on keyboard

Wow…i found a scary discovery, just now I engage with my wife on my Sony Ericsson w810i luckily I’m using my “Dr. Tube” hands free and I put my hand phone on top of my office Dell Inspiron 640M laptop around the “winkey” area and my whole laptop power off by itself. I couldn’t believe it then i power on back my laptop while I still on the phone with my wife, and the laptop bootup to my win xp. I put back my hand phone to the same place i put just now and it happen again… wonder why it happen.

So i wonder is it because I was engage on the phone that makes the laptop power off, then i try again this time without using the mobile for calling or answering calls. Bravo… does not power off the laptop, so I get the conclusion that is the radiation on the magnetic field in the mobile is too high when you engage on the mobile.

So to all mobile user, please use hand free that is less radiation or use same as mine “Dr. Tube” all the time either in office or driving. I’m not making funny or said bad about Sony Ericsson nor Dell product, but its for our own safety and healthy. But I really no idea what cause it to power off, anyone that have encounter the same problem or know why it happen can you share with us what cause it.

Mounting Windows share into Ubuntu Linux

Today my friend (Yeoh) ask me to help him to mount a windows share folder in to a Linux box running on VMware. He is using Ubuntu 7.02 with Deluge installed to download torrent. He don’t want to save the downloaded torrent file into the VMware but into the windows share folder.

So he ask me to help him to do the auto mount the windows share folder. To start off the configuration, make sure the windows pc have set as below:-

1) Windows firewall enable the “File and Printer Sharing”

2) Have share a folder with “Full access” and make sure there is no space in the shared name, try to use simple name.

If you have those set in the windows PC, then you can head to the Ubuntu box and mount the windows shared drive. If your Ubuntu does not have the smbfs type the following to install it:-

# apt-get install smbfs

after install then we create a mount point folder in “/mnt ” called download

# mkdir /mnt/download

# smbmount //<computer name>/<shared folder> /mnt/download -o password=””,rw,dmask=0775

This will mount the windows share folder into /mnt/download folder but will not auto mount after reboot, in order to do that i use the “/etc/rc.local” file to auto mount it. Add the following command in the file.

# /usr/bin/smbmount //<computer name>/<shared folder> /mnt/download -o password=””,rw,dmask=0775

if your windows share folder need username and password then use the following:-

# /usr/bin/smbmount //<computer name>/<shared folder> /mnt/download -o username=<username>,password=<password>,rw,dmask=0775

That’s all, now you can start using the /mnt/download folder.

Bukit Jalil Park

Sunday normally is a family days where all the parent bring their kids to playground or park to gather around playing games or jogging. Me and my wife plan to go for a jogging session on sunday too and we woke up at 7:00 am and drive to our nearest park in Bukit Jalil. By the time we reach there, there is quite a lot of people already start the activities. But we are not that late and we start jog around the park, it is not as small park as i thought about. It really need a good stamina to jog round the park but we only manage jog for about 30 min.

After we done our jogging and had a fresh air, we go for our breakfast in Sri Petaling “old town cafe” for a light breakfast. We had 2 cup of coffe, double kaya & butter bread, garlic bread and 4 pcs of half-boiled eggs.

Home sweet home by the time we reach its only 10:30 am, still got lots of time to spend for the day. We watch movie and clean our room, also make ourself a pasta lunch for my mom and dad too.
