Installing USB asp Drivers on Windows 8
Installing USB asp Drivers on Windows 8.1
When we are dealing with AVR
programming, after create the codes in our development machine we should
write the code into the device. For this purpose, we need a tool which
we called Downloader or Programmer. This tool will “burn” the code into
AVR CPU using spesific port.
One popular tool is USBasp (http://www.fischl.de/usbasp/).
This tool is a USB in-circuit programmer which consists of an ATMega88
or an AtMega8 and a couple of passive components. In short, we need no
special USB controller anymore.
Sometimes, we might face a problem
installing usbasp drivers on Windows 8.1. But, this article will discuss
about how to install those drivers.
Load Balance using PCC method
Load Balance using PCC method
Load balance on the proxy is a technique to distribute the traffic load on two or more lines in a balanced connection, so that traffic can run optimally, maximize throughput, minimize response time and avoid overload on one connection point.During this time many of us who think incorrectly, that by using the loadbalance two connection lines, the large bandwidth will we get into a doubling of bandwidth before using loadbalance (accumulation of both the bandwidth). This needs to be clear in advance, that will not add bulk to loadbalance bandwidth we get, but it only served to divide the traffic from both the bandwidth that can be used in a balanced way.With this article, we will prove that the use of mathematical formulas loadbalancing not like 512 + 256 = 768, but 512 + 256 = 512 + 256, or 512 + 256 = 256 + 256 + 256.In this article we use RB433UAH with the following conditions:1. Ether1 and ether2 connected to different ISPs with large bandwdith different. ISP1 and ISP2 at 512kbps for 256kbps.2. We will use the internal web-proxy and use OpenDNS.3. RouterOS you are using version 4.5 because the PCC has become a popular feature at the 3:24 version.If the above condition is different from your local network conditions, the configuration of which we will describe here should you adjust the configuration to your local network.Basic ConfigurationHere is a network topology and the IP address that we will use
/ip address
add address=192.168.101.2/30 interface=ether1
add address=192.168.102.2/30 interface=ether2
add address=10.10.10.1/24 interface=wlan2
/ip dns
set allow-remote-requests=yes primary-dns=208.67.222.222 secondary-dns=208.67.220.220
For client connections, we use the wireless connection on wlan2 the client IP range 10.10.10.2 s / d 10.10.10.254 netmask 255.255.255.0, which is attached to the IP 10.10.10.1 wlan2 serves as a gateway and dns server from the client. If you are using one of the DNS from your ISP, then there will be additional mangle would we give a thickAfter configuring the IP and DNS are correct, we have to install a default route to each of us to ISP gateway IP routers forward all traffic that is not connected to it to the gateway. Here we use the check-gateway feature is useful if one of the gateways we broke up, then the connection will be deflected to the other gateway./ Ip routeadd dst-address = 0.0.0.0 / 0 gateway = 192.168.101.1 distance = 1 check-gateway = pingadd dst-address = 0.0.0.0 / 0 gateway = 192.168.102.1 distance = 2 check-gateway = pingTo setup the Access Point so that the PC can connect to the wireless client, we use the command/ Interface wirelesswlan2 set mode = ap-bridge band = 2.4ghz-b / g ssid = MikroTik disabled = noIn order for the client pc can connect to the internet, we also have to change the private IP to a public IP client that is in us is the public interface ether1 and ether2./ Ip firewall natadd action = masquerade chain = srcnat out-interface = ether1add action = masquerade chain = srcnat out-interface = ether2Until this step, the router and the PC clients are able to access the Internet. Ping the router or the good of the client pc to the internet. If not successful, check your configuration again.
How to Make a Hotspot in Mikrotik
How to Make a Hotspot in Mikrotik
Mikrotik Router is a router which has a full-featured. One feature that is quite popular and widely used of the Mikrotik Router itself is a hotspot. Do you know the difference with the usual internet sharing Hotspot? Perhaps you often find that the wifi internet signal in the password using WPA or WEP. You will be able to surf if you enter the password correctly. So anyone can access wifi if know his password his password because there is only one. Unlike the Hotspot method, in which most of the wifi hotspot is not in the password and all users can connect then be redirected to the login page in the Web Browser. Each user can log in with the username and password that is different. Methods of this kind that we often find in wifi Cafe, school, college, or other public areas.
Well, now we will discuss Tutorial Mikrotik Indonesia to try to make and proxy settings as Hotspot. But first you need to know what are the advantages of using Mikrotik Hotspot. By using Mikrotik as a Hotspot, you can configure the wireless network that can only be used with a specific username and password. You can also perform management on the user-friendly. For example, set the total duration of the hotspot usage per user, limiting how much data can be downloaded for each user, set what content may be accessed user, etc..Okay, not you already know what are the advantages and features mikrotik hotspot. Now Mikrotik Further Study abroad directly into his practice. We start with a basic configuration of its hotspot was yes.1. Specify the interface to be created hotspot. Because we will make the hotspot via wifi then select wlan interface. Here I assume using wlan1. Enable wlan1 and use AP Bridge mode, input the SSID with the name of your hotspot.
2. Give wlan1 interface IP address, for example 192.168.100.1/24
[admin @ MikroTik]> ip address add address = 192.168.100.1/24 interface = wlan1
Or it could be through Winbox, go to IP -> Address
