I have setup dns on my rhel 5 server. It is working fine. My dhcp server is setup on my sonic firewall. The sonic firewall hands out our IP addresses. My dns server sees the static IP addresses but how do I get name resolution setup for dhcp?
View 1 RepliesFriends i got an opertunity to configure ddns in my office.I already configured staic dns in linux, but this is the first time iam configuring ddns.I just configured ddns in rhel 5.2 in my office.So far every thing working fine,dhcp is giving ip address to the clients and both forward and reverse dns database is updating.
1) In windows we can use flushdns and registerdns commands to update the dns database, like this any command is in linux to update client details in dns database?
2)how to restrict multiple client entries keeping in dhcp database.
3)if i change client hostname it is not updating the dns database,it is keeping the old one.
I am using DELL Studio 15, Windows Vista Home Premium. I have a dual boot of Linux (RHEL 5). My question is how to configure Internet access in my PC in LINUX OS. Windows mode :
how do i access Internet :
I insert a LAN cable to my laptop and access internet. or I insert the cable to my wifi router and access it wireless whenever I am bit far away. RHEL 5.0 Linux 1) UNABLE to access internet when I connect the lan cable to my laptop. 2) Is there any way i can access internet or should i use any drivers that are provided my dell pc. I am very new to linux and i am not sure to which and how to use it.
I have two virtual hosts that I want to be able to send through one router. I have two seperate dynamic hostnames on dyndns.
Apparently my router allows me to enter two seperate hostnames locally as well: DynDNS Host and Domain Name
Code:
How do I tell the router which is which? Currently I see the same site with both URLs
Do I have to set one vhost to do some 'funky' stuff (black hole in my head when it comes to static routes or BIND? ). And then set the other vhost to host both sites?
I'm running CentOS and an apache webserver. I want to demo a web site 'externally' from two different sub-domains.
I've looked high and low but most examples don't seem to be simply trying to put two different web-sites up to two Dynamic DNS Hosts.
It must be possible, all the pieces are there. I'm just missing the link!
I was thinking about setting up my own mail server. Problem is my ISP will not let me have a static IP unless I upgrade to a Business class service which is just too expensive for home use. As a work around I use a DDNS service from Dlink, which is actually done via DYNDNS.com. So essentially I have mydomain.dlinkddns.com point to my Dynamic WAN IP, and it is all automatically managed by my router.
Is there a way I can haveoint to my mail server without it being a subdomain of my DDNS om)? In other words I would like to have the email someone@mymaildomain.com and not have it be dlinkddns.com or something like that. I know someone has done it, I just have never done it. Not quite sure what to google to find the answer myself either.

View 3 Replies View RelatedDHCP I have working, so is BIND.
I'm trying to get dynamic dns working and am having issues
I suspect this maybe a chroot issue.
I've tried to follow the chroot advise within the wiki for Bind but no joy.
I am running a web server with a public ip that is dynamic. I am using ZoneEdit.com and my WRT54GS router to manage my dynamic ip address whenever it changes. It is working as it should.
However, the subdomains ip addresses are not changing. It still shows the old addresses versus the new address. Is it possible to set it where my subdomains address will change as well?
Right now on my router under the ddns menu, I have the host name set to domain.com. Do I need to make a wildcard?
i've installed bind and dhcp. I'd like to update dns automatically by dhcp. For the reverse-lookup-zone everything works fine. But for the forward-lookup-zone there is still the message denied. But i cannot see a mistake.
dhcp:

# DHCP Server Configuration file.

I have DDNS configured and working for dynamic addresses, but it's not quite right for static addresses yet. The DHCP server assigns the static address, but it doesn't update the DNS sever with the associated host name. Which means I have to use the IP address when accessing the host instead of the host name. How can I get the DHCP server to update the DNS with the host name associated with the fixed-address?Here is my current dhcpd.conf.
Code:
ddns-update-style interim;
ignore client-updates;
[code]....
I've run into a strange issue with a DHCP/DDNS setup whereby when the DHCP server asks the DNS server to add a new host, the forward map is added correctly but the reverse map has the subdomain added twice (e.g. 192.168.25.192.168.25.250)I'm running ISC DHCPd version 3.0.1 and BIND version 9.2.3 on SuSE 9.2 - 32bit.Here is my dhcpd.conf file:
# dhcpd.conf
authoritative;
include "/etc/named.keys";
[code]....
I've configured my dhcp server to update dynamically the DNS zones of BIND9 name server. Everything works ok, except for reverse nslookup:
nslookup 10.141.50.3
Server:127.0.0.1
Address:127.0.0.1#53
[code]....
is possible to edited the default RHEL CD to have it automatically install RHEL based off of a kickstart file that I will store locally on the CD. My plan would be to put a cd in a server and have the OS automatically being installed.
