General :: NETWORKING: Assign Domain To Point To DDNS For Mail Server?
Feb 25, 2010
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.

I am trying to point my domain to my server with a static IP address. My domain is registered with Network Solutions and they ask "Primary and Secondary DNS" settings in their setup. What primary and secondary DNS settings I need to give when I have a dedicated server with static single IP address with BIND installed.

I am thinking of getting a domain name or ten I do not know were to point the domain to?
and what do I need to setup if a user wants a domain name to point to his account on the server? ok more like I want to have a few domains pointing to my user accounts I have setup on the server..can I do this directly or do I need a server domain first before users can get a domain name?
I have a basic setup user web space and ftp and mysql setup
what extra would I have to install or not to be able to get a domain pointed to my server and/or user accounts?
I don't seem to be able to find anything specific on how to set this up anywhere.

I've got a home server running Ubuntu Server 9.04 and several machines running Ubuntu Desktop (9.04 and 8.04) and Windows (XP, Vista and 7). Now what I want to do is to create a domain and directory server similar in function to Windows Server w/ AD and join my other machines to the domain, but am not sure where to start. I already have file shares with Samba but now I want to setup a domain.

I recently decided I wanted a web server so I installed Ubuntu and apache2 on it and it works fine. I installed forums on the site as well and it's working fine to. Problem I don't know exactly what to do with the site so I haven't purchased a domain yet (so to access the site you just type in the ip address).
I know this sounds really weird but I want to know if I can make a mail server without a domain name. I kinda want to use it for e-mail verification for the forum. I have been following this tutorial: [URL] and it seems i need a domain name. Is it possible? Also I am not using Ubuntu server, would setting up a mail server be much easier on there (or rather, does it come with a mail server?)

I'm trying to set up an mail filter for our domain. At the moment we're using ClearOS as the filter, works OK but I still get something through and the blacklist and whitelist doesn't seem to work. I was hoping to set up a mail filter on my own, using Spamassassin and/or something else. It seems I have to buy subscription at ClearOS to make it update better or something. I might just do that, it's just tempting to find a way to do it on "my own". I tried to follow these instructions but I don't seem to go anywhere... ...I began with setting up the base server as it is shown there. I've setup quite a few Linux servers, mainly as firewall/gateway kind of things but also some DNS servers, web servers and so on.
I have one mail server and the mail filter is supposed to be on the outside to filter mail before it hits the mail server.

I have two servers relavant here: mail.domain.com (1.1.1.1) - which is the nameserver and the mail server for domain.com. www.domain.com (2.2.2.2) - which is the www subdomain for domain.com domain.com (cname www.domain.com) - an alias for www.
The zone file for domain.com lists mail.domain.com as the MX server for domain.com. 2.2.2.2 is actually being served web pages as a virtual host. It's real hostname is www.anotherdomain.com. Mail for domain.com works pretty well, in general. However, if I attempt to send mail from www.domain.com (or its alias domain.com), I get "mail for domain.com loops back to myself" in the postfix logs. On 2.2.2.2 /etc/postfix/mail.cf has mydestination = www.anotherdomain.com, localhost. How do I tell postfix on 2.2.2.2 that mail for domain.com needs to be delivered to mail.domain.com?

Im trying to get postfix to filter my outgoing mail and basically drop everything that is not in my hash table.
So far I managed to get this going
Code:
Code:
Unfortunately those rules also apply to incoming messages. My goal is to disallow users on my host to change their "MAIL FROM" to anything they like and restrict them to domains I specify. I'm aware that the local part still is variable and a user of domain "foo.com" could use a email of domain "bar.com", but still some of my troubles would be solved if I get this running.

I am managing a Fedora dedicated server with Plesk 9 and just recently moved the email for one of the domains on the server to Google Apps for business. Unfortunately, I cannot get email messages from the website forms to deliver to addresses on this domain. For anyone familiar with Plesk, I have disabled mail in the hosting settings by un-checking the "Activate mail service on domain" checkbox and there are no accounts in the domain. (Other readings have indicated that this should be enough to allow mail to be directed to the appropriate server). My MX records correctly point to the google apps mail server.
I'm quite comfortable with command line, but I know almost nothing about the sendmail program or its alternatives and my attempts at researching how to set up this relay has been futile. I'm pretty sure I'm using sendmail and not qmail or anything else from what the red-hat style "alternatives" symlinks point to. I've also checked the /etc/mail/access, domaintable, mailertable, sendmail.cf, virtusertable, local-host-names, sendmail.cf, and submit.cf and most of these files are empty (except the .cf files), and the sendmail.cf and submit.cf make no reference to the domain in question.
Here is the output from a sendmail test that was was not received. (Private data omitted of course).
sendmail -v xxx@yyy.com
test email from yyy.com webserver. please ignore.
xxx@yyy.com... Connecting to [127.0.0.1] via relay...
220 my.server.com ESMTP
>>> EHLO my.server.com
250-my.server.com .....
Closing connection to [127.0.0.1]
>>> QUIT
Performing the same test and sending an email to a non-hosted domain works fine.

I want to host 5 websites on my new virtual server so I have created 2 nameservers that point to my virtual server's IP addresses as a glue record. What confuses me is when I create a new domain on my server it gives the new domain it's own nameservers (ns1.thenewdomain.co.uk etc) do I need to change these records so they use the nameservers I created earlier? If I do? Which particular records should I change? I'm running a Unix virtual server with a Plesk control panel.

Friends 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 know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through

I have a server with a static IP that I use as a sendmail server. The problem is that port 25 is exposed. As a result, anybody can login to the SMTP server and send mail from my domain as a user that does not exist as well as email from other non-existant domains. I'm sure there are sendmail options that I can enable to do some checks, like if the user exists on that server or if the domain is the same on the server, etc. I was wondering if you guys can mention a few that I can add to my sendmail.mc file?
I have thought about auth login, the problem is if auth login is on my public port then I won't be able to receive email from gmail because it would be unauthenticated. Also, I only have 1 mail server. I know the ideal solution is to have 2 mail servers. One for outgoing mail/internal mail server where you can enable auth login and the other for incoming mail which just acts as the relay to the internal mail server. That way spammers can't login to send mail out. That's another question I had, how do I configure sendmail to only send email out/in?
Anyhow, so I have to make do with 1 mail server for now. So I decided to add a few rules on iptables. I grabbed the IP range that gmail uses when I receive mail from then and added it to my iptables with the following command.

Since I have a new internetaccount, 2 days ago, I have a problem on my server [Fedora Core 8]. I use it as a router.
eth0 is for the internet.
eth1 is for my LAN.
But since my new internetaccount my server uses eth1 for the internet. This is a line from my syslog:
Code:
NetworkManager: <info> Policy set 'System eth1' (eth1) as default for routing and DNS. I killed the NetworkManager daemon and now it works but this must not be the way to do it? Where do I tell my server that I use eth0 for routing and DNS?

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

include "/etc/named.keys";
