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 go to system > preferences > network connections in 9.10 and import a profile. The vpn seems to connect but I cannot ping computers on the remote network. When I attempt to ping, it seems it can see an ip (DNS must be working) but I can't actually ping the machine or rdp in. I've disabled my firewall and rebooted and that didn't help. What can I do?

When I connect to my company's VPN (it's a Cisco), it connects just fine and displays the broadcast message, but once connected I can't ping anything or ssh anywhere. Not on the private network, not on the Internet [URL], nothing. I can still browse the web without difficulties when connected to the VPN, but no ssh or ping. With ping, it properly resolves the host name, but I get 100% packet loss.
Once I disconnect from the VPN, a ping of [URL] works exactly as expected.
I don't have any firewalls set up on this host that I'm aware of (unless something is installed and configured by default).
I'm using Ubuntu 10.10, amd64 build.

I'm using crux 2.7. I'm connecting from the command line and I successfully get an IP leased. Usually 192.168.1.3
But still I can't ping my router.
I've never encountered this and I'm not sure how to trouble shoot it. The router is working just fine. The problem is with my Crux setup.
I have no internet and no GUI installed yet.

I was given a Cisco IP Phone (model 7962) and CyberGuard Firewall/VPN (model SG300) from my company. So that I can work from home. But I've been struggling for the past couple of days trying to get it to work. The phone successfully configures it's ip; but it hangs on "Registering".
The setup is such:Cisco phone plugs into the CyberGuard and gets assigned a private IP address; 192.168.48.34; from the CyberGuard.
CyberGuard plugs into my Slackware (12.1) box and gets assigned a private IP address; 10.0.0.191; from the dhcpd server on my Slackware box.
Slackware box then masquerades that 10.0.0.191 into my static public address on the internet.
Port 1723 (PPTP) is open in the iptables firewall on my Slackware box. I've also tried disabling the firewall (ie opening all ports) on my Slackware box.
On my Slackware box; via iptraf; I can see traffic between my Slackware box, the CyberGuard, and my company's server.
Traffic such as:
Code:
And on the company's server; the following is observed:
Code:
My company just keeps saying "open port 1723 + 47". But as I stated above; I have opened them. And Internet searches have revealed absolutely nothing. At this point; I am completely lost as to what may be wrong.

I bought a Cisco 1841 to study for a cisco certs. In iptables terms filtered packets are -j REJECT instead of -j DROP. To make things worse telnet and ping replies are on by default.

I'm trying to figure out a simple script to go thought 500 Cisco devices to see if I can SSH to the device. Then display something like this:
10.0.0.1 Yes
10.0.0.2 No
10.0.0.3 No
I tried something like this:
Code:
ssh -q -o BatchMode=yes -o StrictHostKeyChecking=no user@10.0.0.1 "echo 2>&1" && echo "Yes" || echo "No"
When tested the above line it replied No, even if I tried it on a Switch that does not have SSH configure.

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.

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..

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.

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

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.

I have a Belkin wireless router model F5D7234-4 version 5. I switched to DHCP long enough to access the router via Firefox browser and look at all the settings. I turned off all encryption and other security related functions in order to just get it going. The IP of the router is 192.168.2.1 which is the default for this router. It is set to channel 6. I can not ping the router from either of two machines using regular ethernet or wireless. I have very limited experience with routers and am in need of help so I can use this for wireless connection to my living room box to my laptop in the bedroom about 50 feet away.
I tried changing the gateway from the living room box IP number to the router IP number with no success. I don't have anything connected to the internet port on the router. The living room box and the laptop are connected to the ethernet ports on the router. Ethernet works fine. Wireless does not. I compiled and installed the drivers for my wireless card on the laptop, a Realtek 8176 which uses the kernel modules rtl8192ce, rtlwifi and mac80211. ifup wlan0 brings up the wlan interface with these modules loaded. Right now I just want to be able to ping the router using regular ethernet. That would tickle me pink at this point. I downloaded the manual but I just can't seem to make headway.

I am trying to get a Slackware server up and running. I got a static IP working kinda. The computer gets a response when I ping the router but not the internet. Basically it can communicate with other computers on the network but nothing outside of the network. Its not a problem with the router because I have a couple other computer with static IPs. Also the network card works fine as it can get on the internet fine normally.

Previously posted under "Wireless Connection Can't Even Ping Router".I've been using Ubuntu for two years. About a year ago I switched to Kubuntu because I prefer the KDE desktop. Two weeks ago I bought a new laptop: Dell Vostro v13. I installed Kubuntu 9.10 from the live CD and everything worked! Well, almost. I also set up a home wireless network with a new Belkin N+ router from WalMart. When I try to connect to my router, the Plasma Network Manager reports that I'm connected and the assigned IP address, but I'm not truly connected! I can't even ping my own router, all packets are lost.
This problem is intermittent, sometimes I connect fine. I dual-boot with Windoze7 and it connects without problems. Also, if I connect with Windoze, then re-boot into Kubuntu, it seems to "wake-up" the connection somehow and it works. I might also add that I connect without difficulty to other routers in my neighborhood, at work, in airports, etc.My old laptop was also running Kubuntu 9.10, and it connected to the Belkin router without problems, although it was a different wireless card and driver. I also tried Ubuntu 9.10 from the live CD and it also reported a connection, IP address, etc. I couldn't ping the router from that connection either!

I'm running into a curious networking hiccup with my router setup. I have a D-Link DIR-628 wireless router connected to our modem, and a wire running from that to a Linksys WRT-54G (v1.1) in our basement. This setup worked great for a few days, but then suddenly the Linksys stopped routing us to the internet. I can connect to the router page on the Linksys and using the diagnostic tools I can ping the web from there, but none of the computers connected to it can. Everything is fine when connected to the D-Link.
After fiddling around with just about every setting on the Linksys I finally gave up and tried resetting it to factory defaults--and it worked! Everyone could access the internet again. But then, every day or two it locks up again and I have to reset factory defaults again.

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?

I have a box that I installed Elastix on as I'm trying my hand at Voip and Linux. I'm basically very green when it comes to Linux and the console. As I was following a guide @ engineertim.com to securing the box, it asked me to: wget [URL], But I get: Resolving engineertim.com... failed: Temporary failure in name resolution. I searched around and tried configuring resolv.conf to no resolve - :) unintended pun
I changed /etc/sysconfig/network to include GATEWAY=192.168.1.1 From the internet I have a modem-192.168.2.1, a telecom voip box-192.168.15.1, and then my router 192.168.1.1 I'm able to ping machines attached to the router but nothing beyond that. I tried to get the results for ifconfig via putty on this machine but it says command not found. I can get it when I log in at the box in question though.
