CentOS 5 Networking :: Eth0, Eth1, Eth1:0, Route = Get One Gateway For All The Eth?
Mar 4, 2011I need to setup two ethernets in my Centos box. OK no problem both ethernet and 1 virtual works perfect. eth0, eth1 and eth1:0. I'm trying to set up diferent routes for eth0 and eth1/eth1:0 I need eth0 has a 192.168.1.1 gateway and eth1/eth1:0 192.168.1.100 gateway.I think I've tried almost every thing but always get one gateway for all the eth.These are my config..
/sbin/ifconfig
eth0 Link encap:Ethernet HWaddr 00:XX:XX:XX:XX:XX

General :: Primary / Secondary Ethernet Interfaces Via NetworkManager
Mar 12, 2010I have an Ubuntu 9.10 machine with three ethernet interfaces, eth0, eth1 and eth2. eth2 is connected to a private network. eth0 and eth2 are connected to two different LANs. Either one will provide access to the internet. All three networks have DHCP servers. Using Ubuntu's the default settings (And Gnome), when I boot up all the interfaces are active and my system gets three IP addresses. However any attempt to access the internet results in connection timeouts and other weirdness.
I suspect that traffic is going out on one NIC (like eth0) and coming back in on another (like eth1). I'm not sure what's going on. The only way I can access the internet at the moment is to bring two of the devices down with ifdown. How can I configure eth0 as my primary interface so all trafic goes out by default on that interface, while keeping the other two active? Also, I want to make sure Avahi broadcasts properly on all three IPs so that the computers on the LAN of eth1 can still connect to myHostname.local...
Here's my routing table:
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
172.16.151.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
172.16.30.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
10.1.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1
0.0.0.0 172.16.30.2 0.0.0.0 UG 0 0 0 eth0
0.0.0.0 10.1.0.1 0.0.0.0 UG 0 0 0 eth1
I want the 172.16.30.2 network to be the primary one and the 10.1.0.0 network to be the secondary one. My nameservers are also incorrect. It seems like Ubuntu is bringing the networks up in order, eth0, then 1, then 2, and the DHCP information from eth1 is overriding eth0, and eth2 is overriding eth1. How can I reverse this so the DHCP information from eth0 is the "master"? This seems to be an issue with Gnome's NetworkManager.
Networking :: Multiple Ethernet - LAN - Cant Connect To Both The Eth0 And Eth1 At The Same Time
Dec 12, 2010I have 2 LAN ports. one from the motherboard (on board) and the other from a lan card i bought a few days back. one is use for browsing the net, the other for a media player.
problem is i cant connect to both the eth0 and eth1 at the same time. i have to disconnect one of them to connect to the other. and this really gets irritating as it doesnt always work as flawlessly as it should. what am i doing wrong?

General :: Prevent An Ethernet Card From Losing Secondary IPs On Fedora 10 With Shorewall?
Sep 23, 2010I 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?

CentOS 5 Networking :: Eth0 Takes Traffic Of Eth1?
Oct 18, 2010I'm having a problem and despite I have googled a lot cant find the root cause. I have a server with two embedded NICs and centos 5.5 loaded. I need to have one NIC with a fix internal IP address to communicate with the intranet and a second NIC with a fix address from my telephone provider. I know I cant have two different gateways on the net so I configured only the gateway for the second NIC leaving the field empty for the first.
I found that the first NIC is handling all the traffic for both interfaces (eth0 and eth1) and the second NIC is in standby (or doing nothing). This is causing the traffic intended for the second NIC never reach their destination. After a couple days working with the BIOS and other configuration files I tried another way of solve the issue. I put a fix address for the first NIC and another fix address for the second NIC (both in the same subnet) and from a computer pinged successfully both addresses. However if I disconnect the cable for the first NIC both interfaces goes down (eth0 and eth1) and both pings fails. If I disconnect the cable for the second NIC (with the first one connected) both pings still running without any disturbance.
I worked also in a second server with different hardware (different kind of motherboard, different NIC manufacturer, etc.) but the problem is also present in this second server. I was reading about NIC bonding or teaming, but this configuration is not present in the modprobe.conf or in the ifcfg-eth0 files, so I believe the problem is not related with this feature. Do you know what is happening with the NICs and how can I get two really, fully independent NICs?

CentOS 5 :: Forcedeth Device Eth1 Not Present - Delaying Initialization
Apr 4, 2009I'm running CentOS 5.2 on an ASUS M2NPV-VM motherboard. This motherboard includes an NVIDIA nForce 430 built-in Gigabit MAC (network interface). I've also installed a second PCI network interface card (NC100 Network Everywhere Fast Ethernet 10/100). The PCI-based card was configured as eth0, while the built-in NIC was configured as eth1. The machine is used as my firewall/router, so eth0 is my internal interface, while eth1 is my external interface. I've had some intermittent problems with the built-in (eth1) NIC. When booting the machine and it attempts to bring up the interface, I get the following message: forcedeth device eth1 does not seem to be present, delaying initialization From that time forward, there is no eth1, and so no external network, etc. If I try running /etc/sysconfig/network-scripts/ifup eth1 (from that directory), it results in the same error.
Originally, I was getting this error when installing the operating system on the machine. At that time, I was using a 75' ethernet cable (as I was working on the machine in my office, and the external ethernet jack was in another part of the house). As soon as I moved the machine to its permanent location (which is within 2 feet of the ethernet jack), the problem went away. However, I just updated the kernel (via yum) from 2.6.18-92.1.22.el5 to 2.6.18-128.1.6.el5, and now it fails 9 out of 10 times. I'm not even sure what I can do to debug this. I'm assuming there is some kind of timing problem with the initialization. Is there a configuration parameter I can set to allow more time for the initialization to do what it needs to do, to prevent this error?
CentOS 5 Networking :: Unable To Start Eth1 From The Command Line?

CentOS 5 Server :: DHCPD On ETH1: Distribute ETH0-received DNS?
Sep 14, 2009this should be trivial for all you big sysadmin guys My box is a firewall/gateway. ETH0 is on the Internet-side, and is fully auto-configured (DHCP client) from my ISP. ETH1 is on the LAN-side, has DHCPD enabled, and I route the traffic to/from the Internet via iptables (NATting, of course). Everything works pretty good, except for the DNS-server assignment via DHCP: how can I configure dhcpd.conf to assign the SAME dns-server I receive from my provider on ETH0 to all my PC on ETH1?

Networking :: Set A Route For Eth1 - DHCP Clients - To Reach Tun0 - Openvpn Server - CentOS
Sep 21, 2010I have openvpn tunnel setup between two CentOS servers. One of the CentOS servers also acts as a DHCP server for some client computers.
Server A= OpenVPN server
Server B= OpenVPN client (connects to Server A with OpenVPN)
The two CentOS servers can ping each other (172.16.0.0/24) via the tun0.
However, client computer connected to Server B (DHCP server) can't reach 172.16.0.1 (which is the OpenVPN server).
I think I am missing some routing in my "ip route show". Following is the full picture:
What command can I issue to get this fixed? something along ip route add?
There is no firewall service on both end. service iptables stop! I can't bridge eth1 and tun0 as DHCP server might mess up the other side. I can't do a push of "redirect-gateway def1" because then clients loose their IP as they send DHCP requests to Server A.
