I have linux suse installed on VMware, my pc is running Windows XP. I have a switch connected to my ethernet card (also through console cable). When I am on windows I can ping the switch, but from linux I can't. My ethcard is "Bridged" on VMware, I can ping 127.0.0.1.
I installed Redhat Enterprise linux server5. it has two LAN card and two subnet connected to these two LAN card. i can browse network from these two network easily. But i created VLAN on one network card.Now i cant browse network from these VLAN subnet.
I installed apache2 on my Ubuntu machine and I am trying to access the server from another subnet. The server is connected using ethernet and has a static ip address. I can ping from the server to any machine in the other subnet but non of the machine on that subnet can ping the server. iptables does not seem to be running
Code:
# service iptables status iptables: unrecognized service
Step 1 : In Hyper-v Machine i have created two Virtual Ports.
Step 2 : Now for these two diff ports two ip address with different subnet mask(e.g 192.168.9.19 and 192.16.9.20)have been assigned(and have checked using ifconfig).
Step 3 : In Host machine i have added one subnetmask for one machine next one for another machine,however i m not able to ping both the ports from either of the machines having static ip 192.168.9.13 or having ip 192.16.9.107.
Step 4 : If i add same subnet mask for both machine it is pinging properly between 2 machines.
I am using centOS 5.0. After I change from DHCP to static IP address, I cannot ping hosts on the same subnet. The error message says destination host unreachable. Before I made the changes I was able to ping and now even I change it back to DHCP I still cannot ping with the same destination host unreachable message. The centOS is running on VMware on a Windows host.
After pinging 192.168.0.106 (106 is on and other host can ping it), arp -a shows ? (192.168.0.106) at <incomplete> on eth0 I tried different ways by disabling the firewall and and disabling SE protection. No Luck.
I got a VPN Setup, issue is, I cannot ping or talk to any other computer through an external source without typing in the FQDN so for example to ping host: chucknorris
ping chucknorris.work.com.au rather then just typing: ping chucknorris
I do know I'm missing an arguments in my pptpd_options file, but does anyone know what?
I am basically wanting to use my Ubuntu 10.10 computer as a router. Note: Before you say just get a router please note that I am poor/cheap. I have two ethernet connections and one wireless connection on my netbook. I want to share the internet connection that is going into one of the ethernet cards through the other ethernet card and the wireless card.
DSL-->1sr Eth --> 2nd Eth (currently works) DSL-->1sr Eth --> Wireless Card (Adhoc) <--(connects with limited connectivity AKA no internet)
The 2nd Ethernet card already has working internet, but when I connect to the Wireless card (through an Adhoc network), it cannot get an IP (I believe).
I have to ubuntu machine (9.10 and 10.4) with a openvpn tunnel between them.This is the situation:
Code: NetworkA 192.168.0.0/24 | UbuntuA br0:192.168.0.3 (openvpn bridge between eth0 and tap0)[code].....
UbuntuA has one only interface etho and there are two openvpn instance: one bridge istance with br0 and another instance with tun0. UbuntuA is not the gateway for networkA. UbuntuB is the gateway for NetworkB.I need to comunicate between pc on networkB e those on networkA.This is the "ping situation" (no pc tested has an active firewall):
ubuntuA vs ubuntuB: OK ubuntuB vs ubuntuA: OK pc on NetworkA vs ubuntuA and ubuntuB: OK[code].....
I have installed fedora core 8 on my system. But i am unable to use LAN connection. here are the results of some of the commands which give error messages
In my red hat Linux machine there was a Lan card using eth0. IP is asign to that network card and it is functioning properly. I add another ethernet card in my linux machineit was detacted and when i use the commandQuote:[root@localhost root] # ifconfig -ait show me both eth0 and eth1 lan cards.I can see Ip address in my eth1 ethernet card but When I enter into
Code: [root@localhost root] # cd /etc/sysconfig/network-scripts and i use ls command it only show me the file ifcfg-eth1 and with
I have a computer that I use for practically everything. In the same room I have a second computer that I use purely for trialing Linux distributions, It currently has Debian, gNewSense and Kubuntu on it with Grub to choose between. This computer has no keyboard / mouse / monitor, but it has directly wired ethernet to the home network. Is there any way I can set it to be remotely controlled from before / during grub so I can choose from the other computer which to run? I realise I can just crawl behind the desk and unplug the keyboard / mouse / monitor, but I don't particularly want to every time I reboot into a different distro. I also realise that remote access during boot is a security risk so is there a way of allowing only one MAC address to do the controlling?
I install RHEL 5.1 on my system. But my Ethernet card is not detected. I found my Ethernet card is of "ATTANSIC Technology corp L1 Gigabit Ethernet Adapter(rev b0). I already downloaded the driver. Someone tell me step by step process, how to install this driver over RHEL 5.1.
I have TWO L3 + router switch (say switch1 and switch2). I created VLAN100 with VLAN ID 100 in both the switches. I created router 192.168.1.1/24 in Switch1. I created router 192.168.2.1/24 in Switch2. Switch1 is connected with 1.x/24 PCs. PCs are configured with 1.1 gateway. Switch2 is connected with 2.x/24 PCs. PCs are configured with 2.1 gateway. Both Switch1 and switch2 are connected by a trunk to carry VLAN100 data.
1)I have few PCs of 1.x connected to say Switch1 Is it possible for PC with IP 192.168.1.100(x) to ping PC with IP 192.168.2.100(y)?What are the configuration required in both switches to make them communicate ? All the device in both the subnets should ping/communicate with each other.
2)Move PC (192.168.1.100) to switch2. Move PC (192.168.2.100)to switch1.What will happen when PC(1.100) ping (2.100) and vice versa?What will happen when PC(say 1.80 in switch1) pings PC (say 1.100 in switch2) and vice versa? What will happen when PC(say 1.80 in switch1) pings PC (say 2.100 in switch1) and vice versa?
I am unable to connect to the internet at work through the ethernet, previously working. I am not sure of the origin of this problem -- the result of an update or something that I did to the network settings.
In the NetworkManager applet is says Auto Ethernet is connected but I can't ping anything by name or ip address.
The wireless still works without any problem.
I have tried following some of the other threads on similar issues but the fixes proposed on them have not helped to date. And I may have mangled some of the settings files somewhat.
Just installed Fedora 14 from the Live CD i686 on my Dell Inspiron 1521. I can't connect to the SpeedTouch 585 on either wireless broadcom card or the wired Ethernet card.
I can connect to it from the same Laptop on the Vista which is on dual boot on the same laptop.
Further confusing is that I ran Fedora 14 and connected to another SpeedTouch today.
Already checked the Channel on the wireless nic and it's on the same one as the SpeedTouch.
I have a Linux box being used as a firewall with Fedora 10 and shorewall 4.2.10. Secondary IPs are loaded on the WAN (eth1)card through Shorewall NAT and Rules file. The problem is that if there is a network hickup or if the circuit bounces, the primary IP comes back but I have to reload Shorewall to get the secondary ips back. Is there a way so that they can automatically reload or just not go away if the connection bounces?
So I keep reading that bonding ethernet devices is supposed to be easy. I have followed several tutorials and tried a few things on my own, and I can't seem to get it right. I currently have a setup that allows me to ping internally on my network, but when I try to ping externally I get the error: connect: Network is unreachable
Before I bonded the interface my connection worked fine. Here are my config files. I am running centos 5.3 on a virtual machine. /etc/sysconfig/network-scripts/ifcfg-bond0
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 doubt about NS3, can use the actual network card of my computer in the simulator NS3, that is, if my network card can behave as programmed into the simulator.
I installed Fedora 12 on my laptop. I have a wireless connection to the internet that works fine, I attached an Ethernet cable from this laptop to a windows machine. There is a green light.
I can ping my localhost. I can ping the windows machine using it internal IP address via the router. However, the eth0 IP address does not work when I ping to it from the windows nachine. Also, I cannot ping to the windows machine using the IP address associated with the Ethernet connection.
