my network expertise is tenuous at best. This started because one computer on my network is having trouble updating Google Toolbar information. This is a laptop which joins other wifi networks outside of the house.
Code:
BROKEN:~$ ping toolbar.google.com
PING toolbar.google.com (208.68.139.89) 56(84) bytes of data.

I am using an virtual machine. where I need to ping from one machine to another. earlier I was able to ping. But after going to google.com once, I cannot ping back to this machine.
But if I gave ping -I eth1 <IP> then I can ping.
I cannot install any package, so tell me solution which includes not installing any package.
I have a Suse 11.2 machine named "susepc" on a network with some other windows machines. From the Suse 11.2 machine, I try ping winpchere winpc is the name of a windows machine on the LAN but the name resolves to an odd ip address:PING winpc.HOMENET (72.215.225.9)he "HOMENET" is the correct name of the windows workgroup, but the ip address is completely wrong. My LAN is based on 10.20.x.x and the winpc ip address should be 10.20.0.100. I can "ping 10.20.0.100" and it works correctly.Some things:- DHCP server is on the router- pinging from winpc to susepc works perfectly ("ping susepc" resolves to the correct IP address 10.20.0.101 and the pings respond)- "net view" on winpc lists the susepc - SAMBA is installed on susepc- the Netbios name is set to susepc- I have a shared folder on susepc that I can see, create files in, etc. on winpc with no problems.- IPV6 is disabled on susepc- I have tried setting up susepc as a WINS server (Wins Support)
- I have tried setting up susepc as a Local Network Browser
I have installed openvpn on an ubuntu 10.04 server. I run 11.04 on my desktop. It can connect to my VPN server. The problem is, I have ZERO internet access. I cannot even ping an IP address.

I have a server with centos 5 and plesk 9 and I have buy an additional IP address for my server, when i create it in plesk, there is no problem, all its ok I can assign it to a new domain, but the ip only responds ping, none of other services as http, ssh or smtp.I paste here the configuration of files

I'm trying to get dhcpd to use a specific IP address as the source address for responses it uses an IP address for. I coded "local-address 172.30.0.4" in the config file. For some responses it uses this address. For some other responses it does not. In those cases it uses the IP address that is the first on the interface. Is there another configuration I should be using, instead?
View 2 Replies View RelatedA 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

I have a weird problem. My system has two network adapters, one with a 192.x address and one with a 10.x address. I connect to the Internet over a proxy that also has one 192.x address and one 10.x address. The name of this proxy is added to /etc/hosts with the 10.x address. Additionally, the network settings for the 10.x adapter include the proxy as gateway. The 192.x adapter has no gateway. If I ping the proxy, it is correctly resolved over the 10.x address.All my applications are set toirectly connect to the Internet".Some apps (the "good" ones) use the 10.x address to connect to the proxy, while some others (e.g. Firefox, the "bad" ones) use the 192.x address. The latter fail to connect to the Internet because the proxy is configured to let traffic through the 10.x adapter only
View 10 Replies View RelatedI 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 have configured DNS on ubuntu server 8.10 and it is working fine. There is one question I have though. Everytime I ping a LAN device by name I get the reply from the server with only the IP Address.

I have currently installed Slackware 13.1 64bit version on a laptop Acer computer. This computer is connected to my cable service (comcast) modem via a dlink router. This computer has linux and Windows 7 dual boot systems installed. Initially I was able to connect to the internet with either linux or Windows. Now I cannot get on the internet with linux, but I can with windows.
I cannot even ping the address of my internet provider,which I can obtain through windows 7 by running the program ipconfig. When I ping the address, in linux,it gives me the message that "network is unreachable".I can ping it in windows 7.If I run on linux the program ifconfig, it does not even show an ethernet, like it does on my other computer connected to this network.I set the thing up initially with netconfig and used DHCP.As I said, initially it worked.I did not use this computer for some time, and now it has the previously described problems.Where should I start, trying to run this down?I have already done everything I can think of,like powered things off, and reset the cable modem etc.

I just installed my first EVER bind DNS server. I am running bind9 on Ubuntu 10.04. Everything seems to be working great except one thing: If I ping a host that I have set up in bind by its HOSTNAME the pings take 5-6 seconds to reply/print to the screen between each echo response. If I ping by the host's IP address, they echo back very quickly.
I have read that IPv6 can cause this, but I have disabled it in /etc/sysctl.conf and the problem still exists.
I know everyone says this can't be a DNS issue, but this never was an issue with dnsmasq (which i was using prior), and it doesn't make sense that the ping are ONLY slow when pinging by hostname and not IP.
Configs below:
Ping by hostname - there is a 5-6 second delay between each one of the responses:

Ping by IP - the responses come VERY quickly one after the other:

So, I have an Virtual Machine running CentOS 5.4. It sits behind a hardware firewall which also does NAT'ing. I've set up plenty of these, so I know for sure the firewall and NAT rules are set up correctly. From the host, I can ping anything in my subnet and the gateway. But I can't ping anything else beyond the gateway. I can perform DNS queries and when I try to ping, it finds the appropriate IP address.But from the outside, I can ping the PUBLIC address (It's a 1 public to 1 private address NAT, not 1 public to multiple private). I've tried it with IPTABLES on and off, with no change.

View 1 Replies View RelatedHey guys. I have a client computer PXE booting from my host computer and it is supposed to give the client the ip address 172.16.0.100 however instead it gives it the ip address 172.16.0.208.
I have this set up working with two other computers and there is no noticeable difference other than mac addresses for the network card.
Here is an extract from my '/etc/dhcp3/dhcpd.conf' file...
ddns-update-style-none;
option domain-name "example.org";
default-lease-time 600;
max-lease-time 7200;

I have quadruple checked the mac address of the client and it is definitely "00:07:E9:32:16:81" so why is it not giving it the IP address that I have specified?
I have an HP Pavilion A6750F with an AMD Phenom 9650 Quad Core. 8 GB memoryThe NIC is a REALTEC Semiconductor RLT8111/81688 PCI Express Gigabit Ethernet Controller.The actual MAC address for the NIC is 00:24:21:55:DE:40I have loaded CentOS 5.3 on this host three of four times in various configurations and patching levels.THE PROBLEM: The system identifies the NIC as having MAC FE:FF:FF:FF:FF:FF.When this happens, the network connectivity obviously stops working.It identifies everything else OK, just maps the wrong MAC.I'm no sure how to troubleshoot this problem. I tried rebooting a couple times and once that fixed it. Usually it does not. I reloaded (gasp) Windows Vista on it and it worked ok.This last time, I reloaded CentOS it hung on the bootup (ASK ??), I reset it, it rebooted and everything looks ok; for now.
The system says it is presently using driver r8169

I can ping fedora from xp computer but i can't able to ping xp from fedora computer.
I have manully edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file with correct subnet mask and ip address because when i tried to give ip address manully in network manager the subnetmask is replaced with gateway address don't know why.
Now i want to share internet through crossover cable . xp is connected to internet through wireless usb adapeter.
