How to Configure DNS Server on Linux Debian 6

Now we will learn about how to set the dns on the server .
1 . The first step we have to set up the first interfacesnya > nano / etc / network / interfaces > and then type the script :
auto lo
iface lo inet lopback

allow- hotplug eth0
auto eth0
iface eth0 inet static
 address 192.168.40.2
 netmask 255.255.255.0
 network 192.168.40.0
 broadcast 192.168.40.255
 gateway 192.168.40.2

> after that press ctrl + o and enter and ctrl + x > and then restart it with the initial configuration script : / etc / init.d / networking restart > ifconfig to check ip
2 . The second step we install bind9 package , with the command : apt - get install bind9

3 . after installing we edit script from file " db.127 " with the command : nano db.127
let the sentences above . we need to edit is :
@ IN SOA ilma.net root.ilma.net . (
then edit it :
;
@ IN NS ilma.net .
2.40.168.192.in - addr.arpa . IN PTR ilma.net .
2.40.168.192.in - addr.arpa . IN PTR www.ilma.net .
2.40.168.192.in - addr.arpa . IN PTR mail.ilma.net .
2.40.168.192.in - addr.arpa . IN PTR ftp.ilma.net .
then we save
4 . then we go to the menu " db.local " , the command : nano db.local
we need to edit is :
@       IN SOA ilma.net . root.ilma.net . (
and the bottom
;
@       IN NS ilma.net .
@       IN A 192.168.40.2
www  IN A 192.168.40.2
mail    IN A 192.168.40.2
ftp      IN A 192.168.40.2
then we save
5 . further we get into the command : nano named.conf.local > ctrl - k first original script and then type the new script :
zone " ilma.net " in {
         type master ;
         file " etc / bind / db.local " ;
} ;
zone " 168.192.in - addr.arpa " in {
         type master ;
         file " etc / bind / db.local " ;
} ;
6 . that we have to edit this script now we edit resolv : nano / etc / resolv.conf
domain ilma.net
search  ilma.net
nameserver 192.168.40.2
then restart configuration : / etc/init.d/bind9 restart
7 . then type the command nslookup ilma.net

How To Configure Access Point D-Link


        This day, the first time I practice taking values ​​in class XII computer engineering and network.
Initially, I was scared because in my own accesspoint 8 groups of different. I was originally using a TP-Link,
but because I had not shared my end should be heartened to use the D-Link. As a result, I can still configure it. because it was not much different from other AP ... hehe, if my intermezzo too long???

   Phase I: LAN Configuration
1. Attach the Antenna, Cable Power adapter and LAN cable to the RJ-45 port on the AP.
2. Select the mode of use as AP (Access Point)
3. LAN cable to attach it to a computer or laptop. Wait a while.
4. Changing the IP address of your computer by step:

Setting Up the Modem Cisco Router


First Stage Before Starting setup
For the first step setting Cisco Router, open your cisco, then attach the modem that has been prepared by the Astinet. Make sure the modem is supplied already on quality A. Also make sure the modem is also in accordance with the desired bandwidth demand.
Open the email or letter has been faxed by the Astinet and record the serial number and ip public ip given to you by the telecom side. For example given the following information:

    
serial ip: 192.168.53.55,
    
netmask: 255.255.255.252
    
public ip: 202 130 207 208
If the data is already there, it means your modem is ready. And that means you are able to configure your Rooter.
Common At The Stage Setting Router

    
Setting the IP address of the Ethernet
    
First thing to do is setting the IP address for FastEthernet it first. This is important because to simplify the process of setting the next step.
    
Connect Modem to Leaseline
    
Plug the modem into the router is leaseline, then plug in the blue console cable, to do configuration via pc. Of pc running hyperterminal to configure cisco router earlier.
    
Put Information Hostname, Password and other lainSetelah console cable attached, restart your router lah. The first time, booting Cisco will ask questions about the default initial configuration cisco like hostname, passwords, etc..
    
Initial configuration of Cisco Router settings
    
The first time we are doing is setting up a password console, aux, and vty passwords secret way is how:

    
router # config t
    
router (config) # enable secret (pass-you) router (config) # enable password (pass-you)

    
Further settings for the console, vty, and aux way:

    
router (config) # line console 0
    
router (config-line) # login
    
router (config-line) # password (your password) as well as setting vty and aux

    
Next do the settings again to let the current password in the password in encrypted sh run. and all passwords terencryption. How to do this is:
    
router (config) # service password-encryption
    
router (config) # enable password (your password)
    
router (config) # line vty 0 4
    
router (config-line) # login
    
router (config-line) # password (your pass)
    
router (config-line) # line con 0
    
router (config-line) # login
    
router (config-line) # password (your pass)
    
router (config-line) # exit
    
router (config) # no service password-encryption
    
router (config) # ^ Z
    
router (config) # wr mem
    
When finished setting the password, we can now change the hostname in a way:
    
router # config t
    
router (config) # hostname (your hostname)
    
router (config) # ^ Z
    
router (config) # wr mem
    
(Your hostname) #

   
if you need to set up the banner please set the banner on your cisco, here I did not enter because I think does not really matter.
Advanced Cisco Router Configuration Settings

    
Setting Against FastEthernet trouter fa0/0router # config (config) # int fa0/0router (config-if) # ip address 203 130 207 209 255.255.255.248router (config-if # ip address 192.168.100.1 255.255.255.0 secondaryrouter (config-if ) # ip nat inside
    
Against Serial settings Serial 0/0
    
router # config trouter (config) # int serial0/0router (config-if) # ip address 192.168.53.55 255.255.255.252router (config-if) # bandwidth 64router (config-if) # ip nat insiderouter (config-if) # ^ Zrouter # wr mem
    
Setting the IP Route
    
Setting the IP route in order to pass to the outside of the package anywhere via serial0 ip
    
router (config) # ip route 0.0.0.0 0.0.0.0 serial0 /
    
Setting IP Nat
    
Ip nat setting to perform Nat to internal network within a network using the ip nat. The trick pool advance to make public ip ready in natkan

    
router (config) # ip nat pool (pool name) 202 130 207 210 202 130 207 210 netmask 255.255.255.248
    
router (config) # ip nat inside source list 1 (name-pool) overload
    
router (config) # ^ Z
    
router # wr mem
    
Setting To Access List
    
router (config) # access-list 1 permit 192.168.100.0 0.0.0.255
    
router (config) # ^ Z
    
router # wr mem
After going through all the steps above, means that all the settings are finished to Astinet now you just try pinging the ip address on the internet when it is connected means your job successfully. And do not forget to set your client to Gateway on the existing private ip on your cisco router FastEthernet

7 OSI Layers

7. Application Layerserve as application interfaces with network functionality, manage how applications can access the network and then generate an error message.
TCP / IP application layer is the Application. Application Layer has 8 protocol, namely:DHCP (Dynamic host configuration protocol): for IP distribution with a limited number of IP numbersDNS (domain name server): Database engine domain name and IP numbersFTP (File Transfer Protocol): A protocol for file transferHTTP (Hyper Text Transfer Protocol): A protocol to transfer HTML files and WebMIME (Multipurpose Internet mail extensions): protocol for sending binary files in text formNNTP (network news transfer protocol): protocol for receiving and sending news groupPOP (Post Office Protocol): A protocol to retrieve mail from the serverSMB (Server messages block): protocol for the transfer of DOS and Windows file servers
6 Presentation Layerserves to translate the data to be in tranmisikan by the application into a format that can be ditranmiskan through the network.
TCP / IP alpikasi, is the presentation layer. Presentation Layer 4 protocol that have:SMTP (Simple mail transfer protocol): protocol for the exchange of mailSNMP (Simple Network Management Protocol): A protocol for network managementTelnet: A protocol for remote accessTFTP (Trivial FTP): A protocol for file transfer
5 Session Layerserves to define how connections can be made maintained or destroyed.
TCP / IP alpikasi, Layer is session. Session Layer 3 protocol has:NETBIOS (Network basic input output system): BIOS standard networkRPC (remote procedure call): remote procedure callsSOCKET: Input outpu for BSD-UNIX network types
4 Transport Layerserves to break down the data into ppaket-data packets and provide the serial number for the packages that can be rearranged to the destination as it arrives.
TCP / IP Transport, Transport Layer is. Transport Layer 2 protocol has:TCP (Transmission Control Protocol): A protocol-oriented data exchange (conection oriented)UDP (user datagram protocol): Protocol data exchange non-orientation (Connectionless)
3 Network Layerserves to identify the IP addresses making headers for the packets and then routing through the internet router and switc working USING layer-3.
TCP / IP Network Layer is the Internet. Network Layer 4 protocol has:IP (Internet Protocol): A protocol for routing settle itRIP (Routing Information Protocol): Protocol to select the routingARP (address resolution protocol): Protocol to get the information right from the hardware IP numbersRARP (Reserve ARP): protocol to obtain the IP address of the hardware

Previously you should have installed a Mikrotik on your computer. after installation, please follow the following steps:

1.after installed properly execute your Mikrotik
2.enter default user password
username: admin
password: (blank) without a password
3. replace your ethernet name if you want, in which case you can give any name = [admin @ mikrotik]> interface
[admin @ mikrotik] interface> print (see first how many ethernet reply attached)
[admin @ mikrotik] interface> set 0 name = LAN
[admin @ mikrotik] interface> set 1 name = WAN
4. then added the ip addresses
[admin @ mikrotik]> ip address
[admin @ mikrotik] ip address> add address = 192.168.0.1/255.255.255.0 interface = LAN -> ip interface for local
[admin @ mikrotik] ip address> add address = 203.89.31.34/255.255.255.248 interface = WAN -> The global ip antecedent to get from ISP
5. then enter the gateway
[admin @ mikrotik]> ip route
[admin @ mikrotik] ip route> add gateway = 192.168.0.0/24/203.89.31.33 -> This is a gateway for exit
6. then setup a webproxy
[admin @ mikrotik]> ip web-proxy
[admin @ mikrotik] ip web-proxy> set enabled = yes
[admin @ mikrotik] ip web-proxy> set transparent-proxy = yes
[admin @ mikrotik] ip web-proxy> set max-object-size = 1200KiB
7. then add the rule so that the client will use port 80 on the web-proxy to shift gears
[admin @ mikrotik]> ip firewall nat
[admin @ mikrotik] ip firewall nat> add chain = dstnat protocol = tcp dst-port = 80 action = redirect to-ports = 3128
