Networking :: Some Other Host Already Uses Address?
Oct 17, 2010
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
The file /etc/sysconfig/networking/devices/ifcfg-eth0 reads:
#realtek Semiconductor, Ltd. ...
DEVICE=eth0
BOOTPROTO=none
BROADCAST=72.86.26.255
[Code]....

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].....

At 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.

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.

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
PING hostname (204.232.162.92) 56(84) bytes of data.

I'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.

I'm having an issue configuring eth0. I'm using ubuntu 8.10 in a virtual machine (VirtualBox). The correct adapter is being used and it has worked in the past. I've tried placing eth0 in dhcp through the GUI and bash, but always get a 169 address or 127.

host 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 am using Fedora 7 in my server. Currently windows server 2003 (Active Directory integrated with DNS) is running. I want to switch my DNS to Linux. In my small organization there are only 20 users using static IP address and the IP are mostly permanent. so should deploy name server or I just populate eateries in /etc/hosts file ?

If I have a dnsmasq server and it dished out a IP address that I don't want it to and it still gives it to my machine no matter how many times I restart windows and issue ipconfig /renew|release or enable/disable the adapter, how do I force it to give my windows machine an IP I want it to have?
The only way I've accomplished this in the past is by rebooting my slackware system.

this issue which has suddenly occurred on both my Desktop and my Laptop. When I try to configure an IP address to any interface I get the following error....
uadmin@Ubuntu:~$ ifconfig br0 addr 192.168.10.1/24
addr: Unknown host
ifconfig: `--help' gives usage information.
uadmin@Ubuntu:~$
I get this for ethernet interfaces as well. I do not understand what is different as I was able to configure the ip address only the day before yesterday on the laptop..? The Desktop has had this issue for about 3 weeks now.
br0 Link encap:Ethernet HWaddr 32:70:40:91:06:25
inet6 addr: fe80::3070:40ff:fe91:625/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

I changed my ip address to a static one. Hope did it correctly. Now when I try to ssh or sftp I get this.The authenticity of host '192.168.1.28 (192.168.1.2' can't be established.RSA key fingerprint is 6b:31:28:58:ee:2b:77:36:08:64:a1:33:85:3c:f1:1f. Are you sure you want to continue connecting (yes/no)?

I am using Webmin to access a database. I finally acquired a static IP address. After entering it into the allowed host for the PostgreSQL server, I still can't access it through the SQL Manager for postgres in Windows. It doesn't seem to actually make the change. I am the new person managing this database. The old person use to be able to just add an IP address and it would connect. Is there something I am missing that I may need to install?

So the problem is that phpMyAdmin does not want to connect to host name (at remote server) but connects to that same server fine if it's ip address is used. Command line "mysql -h hostname ..." works fine and connects to host name. Mysqladmin also works.
it's giving error:
*****
Error
MySQL said:
#2005 - Unknown MySQL server host 'host.name' (2)
******
I've disabled SElinux and temporarily disabled Iptables but no luck.
Somehow I feel MySQL is not doing DNS lookup when used by Apache/PHP. So it just understands ip addresses.
I found that on MySQL startup you can disable DNS lookup. [URL]
Not sure if it's disabled and how to enable it at startup. Could not find anything at "System" -> "Administration" -> "Services".
Here is similar case with no solution [URL]

I've been for a while trying to configure my apache to host 5 domains as virtualhosts in the same IP address, but seems that neither one makes it through... it always takes first one, because it is the default:
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin xxxxxxx@xxxx.net
[code]....
As you can see I tried the ServerName with the http://, in quotes, without it...

Writing a program that finds the IP address of a host name. Sorry forgot to include the line numbers, but where the $$$ is where the syntax error is. The errors are syntax error before "{" token and syntax error before "if". I've looked throught the code for a couple hours and can't figure out what's causing it. The code is attached below.
#define WIN
#include <stdio.h>
#include <stdlib.h>

I am working on a cluster for a molecular dynamics class and I have to edit my FORTRAN code (only the newest and best for me!). In order to get through to the cluster I have to ssh in. The network on which the cluster resides is behind a firewall, so I have to ssh through the firewall into the network first.
this is fine, I can login and move files and folders as needed, including sftp-ing into host 1, then into the cluster so I can transfer files from cluster to host and then host to me. This gets rather tiresome, so it would be nice to edit the files in place.
The problem is that when I access my code with emacs it launches the emacs client on Host 1, with no mouse support. I know the purists will howl about how I should be using keyboard shortcuts, but I am a chemist and not a programmer, so the mouse is very nice for me. Is there any way I can perhaps mount the cluster using sshfs so that when I open my code it launches a local instance of emacs? Sorry if this is the wrong forum, but I thought it was network related.

I got a bunch of machines (~10) that I share with my co-workers. I have appropriate .ssh file(s) set up so I don't get prompt for password when I try to ssh.Currently I ssh into these hosts and then do a top to check the load before I start using the machine. Because I don't want to be on a busy host.Can someone show me how to write a script that find a least-busy host given a list of hosts to check? (hardcoded is fine)
