Dec 14, 2010I have to do a project on network security.For that i have to capture the packets from the device. I installed libpcap tool in ubuntu. If I give ifconfig -a it lists out eth0, wlan0, lo. I am able to connect to the internet via eth0. But when I give
#include <stdio.h>
#include <pcap.h>
int main()
{
char *dev, errbuf[PCAP_ERRBUF_SIZE];

It says device is null. I'm not able to run sniffex.c program also. All I want to do is to capture the live network level packets and analyse them.
Networking :: Assigning Eth0 To PCMCIA Nic?
Apr 26, 2010Just completed installing Xubuntu 9.04 to my old Dell Latitude CPi and it seems to be working quite well. However I need to assign interface eth0 to my pcmcia network card (as opposed to eth1 or eth2). I have two cards to try out. One of them comes up as eth1 and the other as eth2. There is no eth0 listed when I run ifconfig -a. There is no built-in network cards on the laptop, so I don't know why it won't assign eth0 to either of the cards.
how to assign eth0 to either of the two PCMCIA network cards.

Aug 25, 2009When I create virtual ethernet interface and do a ping -I <v_int> <host> the outgoing address is the one of the physical interface and NOT the virtual interface.Is there no chance that trafic will go out with virtual interface address??Incoming trafic is done well i.e. responds to the virtual interface have the virtual address.
My problem is that I have 2 modems and want to check both default gw behind the modems.
If I do a "normal" ping both are reachable over default route even the modem which is not the default route will not work because ping goes over the working modem.So I have 2 routing tables and want to route the virtual interface to one modem the other to the other modem
Server :: MySQL Cluster With Heartbeat?
Dec 26, 2010I have setup a MySQL High Availability Cluster with two nodes using DRBD & Heartbeat. I have successfully installed the cluster but one question which is still not solved is that Heartbeat monitors failover of network or server failure, etc.
What will happen if MySQL service gets stopped or do not start. This heartbeat-DRBD cluster does not take any action on that part. Now I want to enable this feature too which also monitors MySQL service. I have gone through MON help on web but could not find out any good step by step tutorial.

Server :: Heartbeat Dont Start Automatically On Boot-up
Mar 22, 2011I have configured heartbeat+DRBD on a SLES10 SP3 cluster and that's working fine except when both nodes are down and I turn on only one node. When this happens, the heartbeat don't starts automatically (the service status says it's unused, so the services, IP address and partition don't start automatically too).
I can turn on the heartbeat manually (service heartbeat start) and get the services, ip address and partition initialized too, but I'd like to make it starts automatically because it's possible to have one node broken and the person that will turn on the other node can forget to manually starts the service.
-When the heartbeat is unused on the first node and I turn on the second node, the heartbeat on the first node starts automatically and everything is fine.
-The command "chkconfig heartbeat on" was executed.

Jul 19, 2011I booted an OS from a live CD. The OS boots successfully but eth0 fails to start. I checked lspci, it outputs these Ethernet card details:

ifconfig -a returns only the loopback interfaces lo and sit0. The output of dmesg | grep -I 'eth' is:

I was also able to find the kernel module bnx2.ko. I did insmod and lsmod lists it.

View 1 Replies View RelatedNetworking :: Production Server With Static IPs On Eth0 And Eth0:1 - Getting Private LAN On Eth1?
Jul 1, 2010I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.
My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...
The G5
eth0 - Public IP - full LAMP services on two or three virtual interfaces
eth1 - Private IP 192.168.0.1
The G4
eth0 - Public IP for ssh
eth1 - Private IP 192.168.0.2
Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...
I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).
Fedora Networking :: Why Primary Interface Is Eth1 Instead Of Eth0?
Jan 31, 2010I have two network interfaces on my computer but only one of them is connected to an Ethernet cable. Until now on every Fedora release, the activated primary interface has been named as eth0 and everything has always worked well without any problem. Recently I switched to Fedora Core 12 and surprisingly I observed that for the first time, my primary interface has been considered by the system to be eth1 instead of eth0. I tried to replace the content of ifcfg-eth0 by ifcfg-eth1, yet system gave me an error that there was MAC address mismatching. I conserved their MAC addresses in their files and just replaced other connection parameters ( such as IP ADDR, NETWORK, NETMASK, etc.) but it did't work. When I do "server network restart", the command blocks.
As I try to install oracle on this system, regarding the fact that oracle requires static network configuration on the primary network interface, I don't know how to proceed in order to set eth0 as my primary interface (or rather set the current eth1 to eth0 because it is actually eth1 that refers to my activated primary network card).Just one more time, I would like to remark, that with previous versions of the Fedora Core, on the same computer (with the very same two network cards) I never had problem and I had installed oracle on the system with success, having the statically configured eth0 correctly detected by the system.

Server :: High-Availability HTTP Load Balancer With HAProxy & Heartbeat On RHEL 5.4
Oct 15, 2010I am trying to setup a High-Availability HTTP Load Balancer With HAProxy & Heartbeat using the below links.
I have all RHEL 5.4 servers hosted on VMWare.
[url]
[url]
This is the scenario, as given in the links as wells as my setup.
Load Balancer 1
Load Balancer 2
Web Server 1
Web Server 2
I have followed all the steps mentioned in the links religiously except the 2.2 here, in which it is asking to configure the vhosts. I could not really understand , what is to be placed in /etc/httpd/conf.d/vhosts.conf file and in which Web Server.
Due to this step only, I think I am failing in Failover test given in Point 4.1 here. I am able to open the webpage by [url] which gives the content of Web Server 1 (http1.example.com). But, when I try to shutdown the http service (to check failover), it does not shows the contents of Web Server 2 (http2.example.com)
Although, I am able to succeed in Failover Test 4.2, in which shared IP 192.168.0.120 switches when I try to start/stop the any of the Load Balancers.
