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:
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?
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.
I have UcLinux embedded linux. Hostname is updated in that machine. when I try to capture with MAC scanner tool the host name is not showing only IP address and MAC address is showing.Some IP phones are connected in the same network by which the hostname is shown in MAC scanner tool.how to go ahead to achieve the host name in the MAC scanner tool.
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:
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?
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 working behind a http proxy (172.30.x.x:3128). I have configured it in my terminal. All the applications such as wget,lynx firefox etc. are working correctly.However all dns utilities like nslookup, host and even ping too are not working.Following is output of host command:
Code: root@ding:~# host google.com ;; connection timed out; no servers could be reached Output of host -T:
[Code]....
To connect to net I have to first run dhclient3(learnt from this forum!).It gives me my ip but where is dns address sent I don't have and idea.
i have a udp server running at port 60178. when i connect to it from localhost there is no problem. when i use the client from a remote host i am not able to connect. I changed my server firewall settings[Fedora 11] and added "udp 60178" to trusted ports but still nothing happened. I ran wireshark and observed that packets are coming to the server machine but server returns a "Port Unreachable" ICMP message and doesnt give the packet to the application.
Our company uses a customized vpnc (based on and almost the same as vpnc 0.5.3). I first tested it on a Windows host under Virtualbox everything works straight away. But when I want to use it on a Linux host directly it always ends in "No response from target". I have tested this on Fedora 12 and the latest Ubuntu. I thought of firewall settings but iptables -L on Ubuntu returns an empty list even.
When i am trying to access the any directory other on port *80, its not being accessible from the static ip which is routed through a DMZ server. http://122.165.35.9:8085 something like this returns the error "could not connect to web browser"
I'm using Ubuntu 9.10 on a Lenovo ThinkPad T61 using an Intel PRO/Wireless 3945ABG. My laptop's ability to connect to a wireless network stopped last night, and I'm not sure why. It's definitely something on my end, as my roommate can connect to the internet on a Windows box. I can wire in without a problem, but that's a pain and my Ethernet cable got lost in the shuffle when I moved back to school. I've been able to get into this network before and nothing about it has changed. I've been able to hibernate and restart and such and nothing has ever needed to be reset.
The router's a D-Link WBR-2310. Wicd and Network Manager see the network (I'm back to using wicd) , but wicd appears to get stuck at "Obtaining IP address..." and says "Unable to connect: Cannot obtain IP address". I know my password is correct (I set up the router and I'm the CS undergrad in the apartment so I manage it), lspci sees the wireless card, ifconfig and iwconfig return information about the interface, dmesg|grep wlan0 doesn't seem to have anything terribly out of the ordinary, but here's that output:
Code: allyanncah@taliesin:~% dmesg | grep wlan0 [ 23.514202] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 36.609016] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 38.756143] wlan0: direct probe to AP 00:24:01:cb:4e:7e (try 1) [ 38.758791] wlan0: direct probe responded [ 38.758796] wlan0: authenticate with AP 00:24:01:cb:4e:7e (try 1) [ 38.760587] wlan0: authenticated [ 38.760609] wlan0: associate with AP 00:24:01:cb:4e:7e (try 1) [ 38.763318] wlan0: RX AssocResp from 00:24:01:cb:4e:7e (capab=0x431 status=0 aid=1) [ 38.763322] wlan0: associated [ 38.765502] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready .....
I've tried: - reinstalling wicd - uninstalling wicd and installing network-manager - restarting - shutting down and booting back up - restarting the router - sudo /etc/init.d/networking restart - taking the interface down and back up with ifconfig
I haven't changed anything recently in regards to my wireless card, and all the fixes I've tried are things I've done before without an issue. The only thing I'm wondering about is if doing a hard reset might have broken something (I know this is a cardinal sin, but there's a whole 'nother problem I haven't been able to fix with the OS hanging every once in a while over a VPN daemon when it tries to shut down or restart -- I've left it for hours to see if it actually gets anywhere and no luck, won't do a soft reset). I'm nervous about reinstalling the driver just because I've never had to do it and drivers are a finicky business. I imagine there's a config error somewhere?
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....
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.
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?
