We have Verizon as our ISP with a dynamic IP address. We published our website but the IP changes frequently. How can we set Network address translator(NAT) so our website can be published regardless of IP changes? We don't have domain name and have no intention for one.

I am running my own Postfix mail server. Some time ago I noticed that most email was rejected because of the server's dynamic IP address. So I got a fixed IP address. However then I noticed that some mails got rejected due to failing the reverse DNS check. So my ISP told me to get a range of IP addresses and they could then create a PTR record for one of those addresses. That is now running but it turns out that the IP address used for the PTR record is a ... dynamic IP address. So Spamhaus PBL rejects my emails again.

View 6 Replies View RelatedThe issue I'm having is that browsers in Ubuntu 10.04 stall at the part of the process for loading web pages that is noted by the "Looking Up (website address)...". The page eventually continues to load, but it takes a long time. This problem effects all browsers on the machine (tried Firefox and Chromium). It is not a problem with the connection, because a Windows 7 laptop and even the Windows XP partition on the Ubuntu machine function as they should.
View 9 Replies View RelatedMy new line provider/ISP won't give me a static IP address - it's DHCP or nothing. Is there some trick I can use to allow myself to host a web page? I was thinking of getting a static address elsewhere, like at my sometime place of employment, and redirecting, but it just moves the problem downstream.Realistically, assume I leave my computer on and hardly ever reboot (CentOS is pretty stable), then will I typically keepthe same address for weeks or months at a time? If so, I could live with logging in to my registrar a few times a year to change the address, as bizarre as that would be

I have tried to run the "host" command against different DNS caching servers I have access to all produced the same timed out error. I called Aeroplan technical support to report the issue to them and from their perspective, they have no problem accessing the website.And we don't have any problem accessing any websites ourselves if "host" return A record lookup without the timed out error.
1. It's not our firewall filtering out packet. I tried it on external facing server without firewall and got the same result.
2. It's not our DNS caching server cause same errors are observed on our ISP caching server.
3. It works on an altogether network, from a Windows Vista desktop, through IE 8.
I am setting up a server, with a static IP address. I thought I did the setup correctly, including setting up the static IP address. When the system restarted, I saw a message flash about some other host already uses address 72.86.26.xxx
Then, once logged in, I got a system message: System is not receiving updates, check network connection.
I went to System: Network Configuration, and under Devices, I saw:
Inactive Device: eth0
I clicked on activate, and I received the same message: some other host already uses address 72.86.26.xxx

So a friend and I are new-ish to linux (I am reasonably comfortable with basic /etc text editing, command admin). We are, however, completely new to programming and (x)html. We have a few (what we think are) interesting ideas for dynamic websites.Ideally we would like to develop our own course of study to get to the point where we have a basic understanding of programming so that our adventures in the programming of a dynamic website would be possible. Much of what we need learn to do is the following: use daily updated public-domain data from several other sites, manipulate that data algorithmically, which would then yield updating output on our site. Here is what I would like to do:
1. learn the basics of programming with a language that would teach good code habits and fundamental understanding.
2. become comfortable with (x)html
3. learn another language for the extension of (x)html into a dynamic data-heavy website.
Question could you please suggest a way about going about 1>2>3?Ideally the language of (1) would be something that would not be "wasted" just on web design etc. As a language, C really appeals to me. However, if learning this wouldn't lend itself to being helpful in learning another language for webdesign maybe I shouldn't use it(?).If (1) weren't to be C, what language would be funadmental enough to teach good coding but also be helpful in learning (3)
This is a fun one (x used in place of real IP's and hostnames):
Code:
$ host 134.174.xxx.xx
xx.xx.174.134.in-addr.arpa domain name pointer xxx.xxx.xxx.com.
$ host xxx.xxx.xxx.com
[Code].....
What is the command to show the host name of the ip address?Suppose, I've an ip address like 209.191.122.70, now I want to know its host name.What is the command for that?
View 7 Replies View RelatedAt work we run DHCP. hostnames have the format: computername.city.mycompany.com
I have a laptop runing Fedora 13 and a desktop I use for backups, etc. My laptop is named copernicus. Desktop is named galileo. If ping either hostname from itself I get back the localhost IP address. If I ping the fully resolved hostname it tells me unknown host. The desktop is exporting an NFS share I use for backing up work data. I need the laptop to be able to resolve host names to mount the share since we use DHCP. The desktop is dual boot and if it is booted into windows my laptop can resolve the hostname properly. What do I need to do in Fedora to get it to register a hostname with the DNS and/or DHCP server? Should the domain and the search path below both say the same thing?
Here is resolv.conf on the laptop (I am at home). The desktop looks the same, except for a different nameserver. Both computers can resolve other hostnames, just not each other.
A brief description of my network:It is a small home network consisting of an Ubuntu 10.04LTS server edition, an Iomega ix2 NAS, a WinXP pro server and several family laptops.This is all routed through a Netgear WNDR3300 home router. All are assigned IP's via DHCP and all but the laptops are static (via DHCP though). The WAN address/DNS is assigned via DHCP from my ISP.The problem:When one of the machines is offline, Ubuntu does not resolve the netbios name correctly. No surprise here. But what is happening is that it is finding some arbitrary machine on another network. Below is what a ping to an offline host reveals:
Code:
ping -c3 hostname

View 4 Replies View RelatedI need to obtain daily dynamic IP address from my router for remote user. In order to get into the router page, I need to login to it with ID and password.

The router can only access through web interface and below is what I copied from browser.
Is there any one know how to deploy a remote OS installation for a host with public network address? In a LAN with private network, we can use PXE, kickstart... but what we could do with the hosts have only public ip address?
View 2 Replies View RelatedI'm trying to troubleshoot some strange networking problems. The pattern seems to be that only newer distributions are affected. CentOS 5.4 and Ubuntu 8.04 work fine out-of-the-box. But Arch, Sidux, AntiX, Fedora, etc. show the same pattern of errors.Certain websites cannot be found unless I disable ipv6 in Firefox. And certain addresses cannot be resolved using various terminal commands (wget, apt-get, yum, etc.). What I would ideally like is a permanent solution, perhaps changing some settings on my router, so that I don't have to deal with this each time I test-drive a new distro. I have a hunch the issue has something to do with my DSL provider (Fairpoint) filing for bankruptcy.
One more piece of information that may or may not be relevant: I recently switched a website from one hosting company to another. I noticed there was a delay of several days where I saw the old version at the old host, but viewing the site at a friend's house or the coffee shop showed the new site on the new host. This leads me to suspect DNS issues perhaps, but this is not an area of expertise.

View 4 Replies View Relatedhost is windows 2003 server 64-bit
guest is ubuntu 9.04 server 64bit
Qemu : 0.11.1
Qemu manager: 7.0
from Qemu manager, if network card is using User Networking, it's a NAT and I can see that Guest Ubuntu has an ip address 10.0.2.15 and is able to access the internet. However, as Guest ubuntu is running server so I want to do use Tap networking and I assue with Tap, the Guest ubuntu will get an ip address which is in the same subnet as host machine by dhcp. so from Qemu Manager 7.0, I changed Network card to be:
NE2000PCI
Vlan Number =0
VLAN Type: Tap Networking
Mac address: tap0's mac address from host
TAP Network Adpator: Tap0
Note that tap0 was created by openvpn. and then fired Ubuntu guest, ifconfig shows no ip address on eth0 (which has the same mac address as Tap0) so the guest Ubuntu has no ip address and can't access public.
I'd like to implement a dynamic menu which will allow me to specify an IP address and read it into memory. This is what I've got so far (it's fairly basic...)
Code:
IPS=`ifconfig -a | grep 'inet addr:' | awk '{print $2}' | tr -d "addr:"`
PS3='Select an option and press Enter: '
select i in $IPS
do
case $i in
$i) echo $IPS;;
esac
done
echo $IPS
At the moment it just says "Which IP would you like to use" and then freezes, most success I've had is it showing all the IP's listed in ifconfig and then showing the same menu.
I have 4 servers that I got at auction and they now have ubuntu running with gnome interface.I installed apache2 and tried to edit the conf file but i am not sure if it is a router issue a dns or the config.I am trying to figure out how to set the server to hold the domain from a dynamic ip address and also how to create some test page to see if i can acess from the internet.
I have purchased some books on the command lines and how ubuntu works, I am understanding it so far, but dont know how to have a directory for the dns request to point to for the sitewhat i want to do with the servers...voipeb server for about 4 websites - one is for a volunteer rescue organization, another for a test auction site and 2 portfolio sitesremote file access- if possiblealso on a side note, is it possible to have a message relay from one cell phone or transmit to the server and have it send sms message to cell phones? - this will be used for the rescue group as well.
I've heard that all one needs to do to host a website is to install apache2 and then create my own webpages in /var/www. Like I could start out putting a file "index.html" in /var/www and it would show up on the web.If this is true, what would my website address be on the web?

Trying some other pages and it really is the www that screws it up: For instance URL... does not work whereas URL...does. What is wrong??I could go back to the old setting but obviously i have a reason for the second router which is setting up a small network for printer and file sharing.
