I PHAILED!

APSTNDP baru tiok.

Haha ... k cool ~ one contract signed

You mean OSI?

I don't allowed noob in my company. Only got talent people then can go inside

It depends. There are many types of VPN implementation. Some uses the SSL/TLS security means they are somewhere Transport layer and Security layer. The network layer may also be affected because there are some IP reassignment and mapping process being done.

Kenneth, you're currently studying on CCNA? meaning more on routing and switching?

specialized in routing and switching.

Hah .. but I see you got talent,make can me a design for my White Wing Lab's in the future

That's a good talent seriously

I think that is called Heartbeat. Active-Active

This name ahh .. hm ...    ~
Yeah,can pay him a little then he make me  a good one ~

  Bullying inexperienced small fud by paying low salary. That's the most pantang thing in freelance industry.

Saw one classifieds in Codemasters. Online Shopping System for RM200-300.

I would want to scope it down to just login and registration module, with some basic content management for that fee.

That will cost them extra if they want billing capabilities.

Yeah. Something like a floating IP. I remembered my client asks us to use that IP so my system will never know that the server is down, because the switchover process is seemless



I'll always access 192.168.0.1 as the server. But the physical IP is 10.0.0.1, So if 10.0.0.1 is down, then the floating IP will take over 10.0.0.2, but from my system's point of view, it will never know which physical server it is accessing.

Some customer will straight away ask:

What commercial database you use? What's the support warranty? What's the number to call if there's a problem?

You wouldn't want to tell your customer:

"Go to forum.lowyat.net"

Haha.. sorry, wrong diagram. Refer to my latest diagram.

Server A and Sever B are two identical servers. Server B is redundant and is a mirror of Server A used for High Availability (HA) scenario.

Some clients are not as easy to deal with as you think.

Not really domain or name server. Domain and name servers are used to resolve IPs, more like a DNS.

Haha,I won't be so jin gak lah , lol ... ~
Yeah,now all in study mode,they don't know their parent in working mode was so hard~ I been facing this since I was 14 and last time almost die ..

Simply put, when Server A is down...


X = No response from Server A

Dun talk old stuff la ,haha ...

I cannot 15 times a day la 
sasaug still young,don't need know ,this is young and dangerous story 15

gu wak chai 15

Yeah .... that time I was almost die is almost same like gu wak chai story

For the outer world (Internet) to access your place, you surely need to suscribe to Streamyx or VPN. Then they will give you an IP one. That's why there's Corporate level of subscription for Streamyx, which provides you a STATIC IP, that doesn't changes everytime you logged on. (Compared to normal user one, it assigns a random number to you)

Actually the 192.168.0.1 is the internal IP. Refer diagram below:


So my PC is 192.168.0.6, which is not accessible by the internet people. They will only see 115.132.107.115, because the router help us create a smaller network inside our house, this helps by saving more IP addresses (Coming near to a limit soon, that's why IPv6 is coming out)
Won't be so jin gak, but will be verryyyy jin gak only right

But will emo woh ~ really wanna know ~
Yeah 
Yes,14 years old.
No la .. dun say like I am a bad boss 
Like that ? Dun know I shall start or not 

Wooo *future Network Engineer detected*   
No lar it's just an illustration, I photoshoped it to give you an clearer idea only haha. But my place got 7 people using computers tho.

Maybe someone is wardriving outside gsrc's house?

even protected with 128bit encryption can be cracked easily...
just need some sniffing done.. 

If tomorrow newspaper headline:

"Hacker Fong Wei Zien arrested"

then I don't know.
