Networking :: Handle Parts Of Public Domain Behind A Router?

Jun 3, 2010

I have a registered domain (let say domain.com ) with a web server (www.domain.com) hosted somewhere online.

I handle the mail part in my private network, by giving the MX my WAN IP (111.222.333.444 )and NAT routing mail stuff to the mail server (10.7.167.3) It works fine.

I will have to handle sub-domains (foo.domain.com & bar.domain.com) and also another domain (anotherdomain.com) in my network. In that case NAT routing isn't going to work ...

What do I need to set this up ? I guess I need a DNS server in my network but I'm not sure if there won't be a conflict somewhere with the Registrar's DNS and mine. Or do I have to take the whole DNS of my domain on this new server and make it half public/half private in some way ?

Ubuntu Networking :: Bypass Router DNS Caching With Public DNS (but Keep DHCP)?

Dec 18, 2010

My router is crap. If I use DHCP it sets all the computers DNS to itself and all DNS requests get cached in the router. It even starts to loose some DNS request if to many are made at once. On my windows PCs this isnt a problem I just set DNS to google's public DNS servers (8.8.8.8 & 8.8.4.4) and bypass my router and ISP alltogether but when i go to pref>network_connections i have to either set DHCP or manual, there is no option to set DHCP with custom DNS.
I'm sure there must be a way to do this in terminal, can someone tell me how?
I'm using ubuntu 10.10.

Networking :: Public Subnet Behind Router - Use IP Pool On LAN Side Interface?

Aug 5, 2010

following are my Linux router information

eth1= WAN IP= 110.88.89.66/32
Gateway= 110.88.89.65
eth0= LAN IP= 192.168.1.1/24
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
MASQUERADE all -- 0.0.0.0/0 0.0.0.0/0
[Code]....

My ISP gave me IP Pool 110.88.90.68/29 to use this on my LAN. my question is how can I use this IP pool on LAN side interface. i think now its simple. 192.168.1.0 /24 is my LAN network and I can not change this, because i have near 180 PCs on my LAN.

Server :: Configuring Sendmail To Handle Addresses But Not The Whole Domain?

Mar 22, 2011

From my main Postfix SMTP heads, I am sending just a couple select emails (primarily support emails) off to a server that receives them and pipes them into the support software. So far this totally works perfectly and I am pretty happy with the configuration. However, in order for sendmail on the support server to receive those emails I have to place them in the virtusertable of course, but I also have to activate their domain in the local-host-names file. That then causes sendmail to consider itself as the destination server for that whole domain.Is there a way to make sendmail receive email for select addresses without making it think it's the server for the whole domain? This server is only receiving email from two specific smtp servers, so I wonder if I could just permit relaying? Wonder if that would just cause a giant loop though.

Security :: Public Facing OpenVPN - Open Any Ports On The Router / Firewall

Feb 14, 2011

Within the documentation of example OpenVPN setups there is a setup that shows an OpenVPN Server with two network interfaces. One interfaces is plugged into the public internet network and the second interface is plugged into the private network.

Normally I assume that it would be best to place the OpenVPN system inside the network behind the router and firewall and open only the ports needed on the router to allow access to the OpenVPN system. All other router ports would be closed. This is the first example they show. To see what I am talking about see page(s) 6-7 here -> [URL]

If one were to use the two interface public facing setup, when would that setup best be justified? I guess if you didn't want to open any ports on the router/firewall then this could be justified but then you have to lock down this public system individually instead of having it protected by the network firewall.

Ubuntu Servers :: Router Will Not Ping Domain Names

Jun 9, 2011

For clairification, I can ping. I have tried several IP addresses and 100% success rate. When I noticed the problem I was trying to run sudo apt-get update && apt-get upgrade After some time I noticed these error messages to start with

[Code]

I tried to ping the adddress security.ubuntu.com from my Windows machine to verify that I could connect and was surprised when I could. I then pinged the address 91.189.92.167 which is what my windows machine resolved the name as and it went though.

My thoughts on this are that when my Ubuntu Router came up, for some reason it did not incorporate the ISP's DHCP servers into the ip address it obtained. Sadly I know to view ALL IP infomation in windows via ipconfig /all command but I do not know what this is in the *nix world. need commands that I can use to check and troubleshoot this apparently DHCP issue so I Can start to update my server and expand on its services?

Networking :: Setting Up Linux Box As IPv6 Router To Replace Netgear WNR1000 Wireless Router?

Jun 18, 2011

I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.

As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?

My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?

Networking :: Set Up A Laptop As A Router To Connect Wirelessly To ADSL Router?

Nov 6, 2009

I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).

I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.

I have added this to /etc/sysctl.conf on the laptop:

net.ipv4.ip_forward=1

Then I tried this on the laptop:

sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT

This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.

But this doesn't work. The connection doesn't even establish between the laptop and the desktop.

Networking :: Network Setup - Router - Wireless Router Card ?

Apr 24, 2010

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.

Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.

Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).

The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.

Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).

Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.

Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).

My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

Here is a link to (picture) my network diagram. Network Diagram

Fedora Networking :: Windows Sever 2k3 Domain Controller / Use Machine With Samba As Secondary Domain Controller?

Apr 28, 2009

At the school i work in i have a server2k3 server that provides a domain to all the windows clients, aswell as a fedora server that acts as an imaging machine and webserver.

Im rather concious of the fact that if for any reason the Server2k3 server was to die there is no backup of active directory, or anything that can take its place whilst a replacement is found.

So is it possible to use a fedora machine with samba as a secondary domain controller? so it can be used as a login server, and has a copy of AD.

Ubuntu :: Use Openssl Public And Private Keys So Only A Host With The Public Key Could Access / Decrypt The Filesharing

Aug 2, 2011

I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive

Networking :: Old Router Behind New Router - Configuration ?

Oct 30, 2010

I've moved a linuxbox from being my gateway (nat, etc) to behind a new gateway (a DD-wrt router). For transparency purposes, I'd like to continue using the old box services, and just have the gateway in front of it.

Here's what I did:

The newgateway is setup for class C, 192.168.0.0

This configuration works, but sometimes it doesn't and I haven't figured out why yet.

At sometimes, clients on the LAN get throughput rates with very little speed loss (using speakeasy speed test). They will run at 33M on the LAN, running through both the newgateway, and the oldbox, and get about 35M with directly connected to the cable modem.

Other times, it seems nothing can talk with anyone, and I am not sure why.

I know what I have done is a little unconventional, but it's a transitional thing, and I am not sure it is the cause of the problem, although it was the last things changed.

Networking :: Nagios - How To Handle Transparent Switches

Jan 26, 2010

I'm configuring Nagios at the moment, but I'm doubting my approach to transparent switches a bit. It seems from reading the documentation that Nagios wants me to ignore transparent switches, although I also doubt this interpretation of mine.

A little example, a VPN:
Code:
demarcation point
|
[router]
/
[switch][switch]
| / |
[7 clients] [switch] [switch]
/ |
[6 clients] [4 clients] [5 clients]

As you can see, there are 22 clients connected to the router. Since switches don't have an address, they cannot be measured. But if I ignore the switches, the schema is an oversimplified picture of reality. So what I'm looking for is a way to display the switches, even though they don't have an address. What I did was, I created the switches as where they proper fully featured ones, and listening to 127.0.0.1 as address. Luckily, this tricked Nagios. And it works, but it's not very elegant. Is there a better way to approach this pseudo-problem? Perhaps a build-in I overlooked?

Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his.
