Fedora :: DNS On Router But Unable To Ping By Name On Network
Feb 1, 2010
The NetworkManager applet on my desktop states that my router is 192.168.2.1 and that my first DNS server is 192.168.2.1, but I cannot ping any hosts on my network using by name. All my other computers are windows so the naming is netbios naming, but I don't know if that makes any difference to DNS. I take it that because the other computers are windows that I need a wins client or something on my Fedora laptop. I would rather not fill out my hosts file because the IP addresses of the windows boxes may change.

when I was still at my university room where the connection would work after a few reboots. After moving back home the connection worked on and off for a day before not working at all. NetworkManager is telling me that I am connected and have an ip address, etc, but nothing is able to get an internet connection. I am able to ping myself but am not able to ping my router. Everything works fine on M$ and other PC's on the network, it's just my ubuntu 10.04 that is playing up.

I installed openSUSE on one of my work system. The network port wasn't working when I was installing, but works fine now (checked in Windows). But for some reason, I am not able to configure the network. I used both Dynamic and Static IPs (both work fine in Windows) but still no go. I am using Yast Control Center for this purpose. I can't even ping the default gateway when I am using custom settings. When I use dynamic settings, it says Unreachable Network.

I have Mandriva One 2009.0 (192.168.1.100) on one box and Mandriva Free 2010.0 (192.168.1.118) on the other. I can ping router (192.168.1.1) from both of these boxes but I can't ping one box to the other and the other way around. What's going on?.
Do I have to change some settings in router?. Or is it firewall issue on those two machines?. Both of these boxes are connected by cable. Symbol of the router: TL-WR340G.

I have installed Micro Core onto a usb of mine and am running it on my laptop. I have been able to successfully obtain a connection and valid ip with my router. As you can see below my wireless connection seems valid computer-end and on my router's page it comes under the list of attached devices.Although this is all fine and dandy, I'm am unable to ping my router or any other computer on my network, I am also unable to ping my laptop from other computers on the network. Also by the looks of it I have having no trouble transmitting, but I am not receiving any packets.

I have two machines on this network, one running Ubuntu and the other running Fedora.
When I'm using the Wireless network on the Ubuntu machine, I cannot ping the Fedora machine. Everything else works. I can browse the net fine.
If I switch over to the Wired Network then I can ping the other machine.
I don't understand why ping doesn't work only over the Wireless. I can ping the router so I'm guessing it's getting blocked by the router but I didn't block ICMP traffic.
I tried asking on IRC and they ran out of ideas too to find out where the problem is.

I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.
I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.
So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page (192.168.1.1) times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?
Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.
We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.

This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.

I did a new install of Fedora 14. This is my first time using Linux seriously and I am trying to figure it all out.
I am able to ping my hostname of sinbad only from the linux system itself. On all my windows boxes, I am not able to ping it. I can only ping the IP address.
Here is /etc/hosts:

I disabled the firewall, disabled SELinux, and still not able to ping it.
Here is the info from ifcfg-eth0 :

Connected freshly installed 10.04.2 to a wireless network through a router. Everything looks correct -- IP is assigned, connection is on, the system shows up on the router -- except that there is no internet connection and I can't ping the router or anywhere else. According to the router, the wireless signal at the ubuntu system is stronger than at the sitting-right-next-to-it windows system with *working* internet. what is this? Should I replace current driver?

just finished installing Centos5 and I had no problems installing it. But when I tried to connect to the internet, the trouble began.My network card is installed and the status is "OK". The network card is a "Realtek RTL 8168C(P)/8111C(P)".The status of the device said "Inactive" and when I tried to activate it, it came with an error: Failed; no link present. Check Cable?Now the cable is connected as it should be.So next step I did is put in a static IP. Now the activation works fine.However I still have no internet. I can't even ping to my router!I need some new drivers for my graphics card too, but first I need the network to work, than I can download other stuff..

I can ping a host on my LAN successfully, but I cannot ping [URL]... for example. I have disabled the firewall and set http_proxy and can browse the internet with "Use system proxy settings" checked in Firefox. I am unable to update with yum either, but I am not sure if this is a side effect or not. I have run a trace on my ip address as I am browsing the internet and I can see the sites I am visiting on our web appliance. However, if I try to ping or update no requests are hitting the proxy so I don't think that is the issue.

I am a new user of Ubuntu...I am trying to use if for a University project. I have installed Ubuntu under a nice new partition and install was smooth. I am using my Belkin F5D8055 v1 USB adapter to connect to my router. The router registers that the IP 192.168.0.3 has connected (thats the IP assigned to the adapter) however even when trying to ping the router (192.168.0.1), I get no response.

Every three or four weeks my router and cable modem will appear to go down. Not only can I not access the internet or web, but I can't even access the router and modem's admin pages (192.168.2.1 and 192.168.100.1 respectively). However, I can successfully ping 192.168.2.1 (forgot to try pinging the modem ip).
Hard resetting both by unplugging them for about a minute or so and replugging them fixes the problem. This is what Roadrunner says to do any time connectivity is lost. This problem also used to occur on Windows as well, except that on Windows I could still browse to both the router and modem's admin websites and restart them remotely. On Ubuntu (both 9.10 and 10.04) I have to manually unplug them since I can't bring up the admin sites in a browser.
I'm not sure how to go about troubleshooting this issue, and why Linux seems to require a manual hard reset whereas it could be solved on Windows with a remote restart. I wouldn't have thought the OS would even have anything to do with that.

I tried to get Ubuntu 10.10 up and running last night, almost worked, but wireless card isn't working. I have another machine in the house running ubuntu 10.4 and it works fine. I have searched around a bit in the forums and can't find anything, so I thought I would make my own post. The wireless card is an Intel PRO/Wireless 2200BG, which I think is part of core (i think i read that somewhere).
I think the problem might have something to do with the ip address (currently 192.168.0.100), i remember having issues in the past with that, but I could be wrong. when I run iwconfig i get

I'm setting up a home network and trying to set up a Ubuntu Server (10.04) as a samba file server and a web server.I installed Ubuntu 10.04 Server and the automatic network configuration during installation failed. I've looked into host.conf, networks, interfaces, hosts and resolv.conf and either my settings are wrong or it's something else. I have a Win7 computer connected to same router and DSL modem and it works fine (edit: most of the time--- see below).
More information:
*ifconfig shows eth0 is broadcasting but without an IP address
*route shows an empty routing table
Code:
sudo route add default gw 192.168.1.254 doesn't work:
SIOCADDRT: No such process
[code]
sudo /etc/init.d/networking restart doesn't work:

I have a desktop computer (Ubuntu) connected to one of the LAN ports of the Cradlepoint MBR1000 router via an Ethernet cable. I also have a Verizon mobile broadband USB modem (USB760) plugged into the USB port of the Cradlepoint router.I also have a laptop (Ubuntu) with a wireless wi-fi adapter (802.11g). The laptop also has an Ethernet card but I'm not using it. The desktop computer does not have a wi-fi adapter, only the laptop does.
With the above setup, I have Internet access to both the desktop computer as well as the laptop computer, which I am well pleased with.Is there a way I can have file sharing between the desktop and the laptop, or at least ping between them, the way I have it set up? I can't use the ad-hoc method because for that to work each computer needs a wi-fi adapter. The router is using DHCP but can also be configured manually.
