Hello,

This is more a configuration error. Depending on how you have your DHCP setup, you may need to adjust it's setting. No mention of what os you are using but if you set your DHCP to give IP addresses only to the LAN, set the ISP NIC address to receive its ip from the ISP provider, you should be able to get Internet access to your server and the LAN.

If you have done so, use the server os to setup your Internet connection. Answer a few questions about how you connect to the Net and the os will do most of the configuration for you.

Good Luck

DHCP Server configuration in Linux


Linux is a UNIX based operating system. It is a server operating system. REDHAT Linux is Enterprise version of Linux. Now a day's Most of corporate sectors use red hat Linux as server in their company because it is secure very much.

Full form of DHCP "Dynamic Host Configuration Protocol. DHCP server assigns IP addresses and other network configuration information like subnet mask, broadcast address, etc to computers on a network. The DHCP assignments are the following.

Lease Request: Client broadcasts their request to DHCP server with a source address of 0.0.0.0 and a destination address of 255.255.255.255.
IP lease offer: DHCP server replies with an IP address, subnet mask, network gateway, name of the domain, name servers, duration of the lease and the IP address of the DHCP server.

Lease Selection: Client receives offer and broadcasts to al DHCP servers that will accept given offer so that other DHCP server need not make an offer.

The DHCP server then sends an ack to the client. The client is configured to use TCP/IP. Lease Renewal: When half of the lease time has expired, the client will issue a new request to the DHCP server.

Installation of DHCP server: First of all while install the RedHat Linux enterprise version server be careful about the ports and the services must be turned on. To create DHCP server in Linux first download DHCP RPM package and install with "rpm-ivh" command. Where I have done it there I have create YUM server, so easily I have download and install it by YUM (yum install dhcp version). DHCP package will locate in /usr/share/doc/at Linux file system. I copied the DHCP's files from /usr/share/doc/ to /etc/dhcpd.conf.. Then I started to configure the dhcpd.conf file to route the DHCP server in there local network. I have open the configuration file with "vi" command. Then commented out the lines from "default gateway to option netbios" because system don't read the commented lines. After that I set the range of IP address in dynamic- bootp of their local assumption of system. I have change the "next-server" with the dhcp server name and have also change the fixed address with the dhcp server IP address (end range of dynamic IP). It is very easy job to configure DHCP server. After configure the .conf file of dhcp just turn on the service with "chkconfig" command and restart the dhcp service. After that entire job I reboot the system. And after rebooting of server I turned on the other client system. While startup the client system without static IP address all of those picked up IP from dhcp server and going on successfully. I have prefer the command line mode to do the total job.
The DHCP server configure file is following:

ddns-update-style interim
ignore client-updates

subnet 192.168.1.0 netmask 255.255.255.0 {
# The range of IP addresses the server
# will issue to DHCP enabled PC clients
# booting up on the network

range 192.168.1.201 192.168.1.220;
# Set the amount of time in seconds that
# a client may keep the IP address

default-lease-time 86400;
max-lease-time 86400;

# Set the default gateway to be used by
# the PC clients

option routers 192.168.1.1;
# Don't forward DHCP requests from this
# NIC interface to any other NIC
# interfaces

option ip-forwarding off;

# Set the broadcast address and subnet mask
# to be used by the DHCP clients

option broadcast-address 192.168.1.255;
option subnet-mask 255.255.255.0;

# Set the NTP server to be used by the
# DHCP clients

option ntp-servers 192.168.1.100;

# Set the DNS server to be used by the
# DHCP clients

option domain-name-servers 192.168.1.100;

# If you specify a WINS server for your Windows clients,
# you need to include the following option in the dhcpd.conf file:

option netbios-name-servers 192.168.1.100;

# You can also assign specific IP addresses based on the clients'
# ethernet MAC address as follows (Host's name is "laser-printer":

host laser-printer {
hardware ethernet 08:00:2b:4c:59:23;
fixed-address 192.168.1.222;
}
}
#
# List an unused interface here
#
subnet 192.168.2.0 netmask 255.255.255.0 {

I can't find the settings to enable a public IP for my dns server. Where are they or is there another way?


Telephone your ISP -- they can provide this information.

However, most ISPs use 'DHCP' ("Dynamic Host Configuration Protocol") which automatically provides IP-addresses of DNS-servers to any device (your computer, or your router) connected to the cable-modem.

This option is recommended for most users.

You may have to or prefer to manually configure the IP settings, especially when a static IP address is used. This is necessary only if your ISP has issued a static IP address, or if you have configured the router to issue static IPs (and DHCP is not used). To manually configure the settings, select Manual, and then enter the IP Address, Subnet Mask, and Gateway by using the keyboard on the screen. When the information is complete, select Done.

Make additional DNS


Yes, all Windows Servers have the option to install DNS.

Set up a second Windows server and configure it to be a secondary server for your DNS domains on you current server.

Add the second DNS server's IP address to the secondary DNS field to your DHCP scope options and to all computers with static IP configuration so they will use it when your primary DNS is unavailable.

Don't underestimate Window's built-in Help and Support. It will help you install DNS and configure it.

Good luck.

You do not need to configure ISP's PTR records. Instead define their DNS addresses as forwarders in the properties of DNS server under forwarders tab and flush DNS cache.

Dns error 80710102


Hey peterk18,

First of all, how is your network configured? Are you behind a router? What's it's IP adress, does it act as a DHCP server?

If so try to set up a new network connection and put everything to automatic.. When the routers acts as a DHCP server it will give the PlayStation 3 an IP adress. DNS however is something else. DNS is a system that allows you to browse by a website or hosts name. For example: it allows you to type www.google.com in your browser instead of it's IP.

DNS is essential for Internet. Your router should be your DNS server and your router itself also needs to know a DNS server, this would be the server from your ISP. All these settings are automatically configured via DHCP.

Greetings,
