I know how to use 'ip' to set up a static route, e.g.: ip route add 192.168.128.0/17 via 40.53.24.3 dev eth0 But if you reboot or restart network, you loose this. Thus you have to make it persistant. I found: http://www.cyberciti.biz/tips/configuring-static-routes-in-debian-or-red-hat-linux-systems.html where it says to add to ifcfg-eth0: 192.168.128.0/17 via 40.53.24.3 But this

Hi, I'd want to configure persistent static routes, ie in config files, but I can't configure static routes, I tested: [root at centos7 ~]# cat /etc/sysconfig/network-scripts/routes-enp0s3 ADDRESS0=10.10.10.0 NETMASK0=255.255.255.0 GATEWAY0=192.168.1.1 logs says nothing: ago 27 15:38:29 centos7.vhgroup.corp NetworkManager[2299]: <info> Activation (enp0s3) Stage 5 of 5 (IPv4

Dear Friends I have 2 netcards (eth0 to Internet and eth1 to internal network) in CENTOS 4.2, bit when I boot system the up eth0 and et1i [OK]. When I run ifconfig the eth1 has not IP configure, then I run command ifdown eth1 and ifup eth1, after eth1 is work perfect. Below I show file /etc/sysconfig/network-scripts/ifcfg-eth1 # Please read /usr/share/doc/initscripts-*/sysconfig.txt # for

I added a virtual interface eth0:1 on one of my machines and suddenly networking breaks on startup of the system (eth0 is gone) when xend starts and runs the network-bridge script. This is supposed to be fixed according to: https://bugzilla.redhat.com/show_bug.cgi I checked and the network-bridge script contains this fix. It works fine on one of my PCs when eth0:1 is added, but not on this

Hi, I'm working with the iproute2/iptables toolset on my CentOS4 server to create custom routing rules. However, I'm a bit at a loss how to create these permanently so that they are automatically reloaded upon reboot of the server. I know that iptables has a config file in /etc/sysconfig/iptables that is loaded by /etc/init.d/iptables startup script. Is there anything that works

I have the following networking setup: - eth0 and eth1 corresponding to the physical ports on the host NIC - bond0 which enslaves eth0 + eth1 - br0 which attaches bond0 - xenbr0 - xenbr5 all of which are internal only networks (10.0.0.0; 10.1.1.0; etc) Br0 is used both for the host to access the outside world as well as DomUs acting as gateway machines for each xenbr network. For example the

Is it possible to have a route stick in the kernel, even if device it points to goes to roller coaster up and down drive. For example. I have an ADSL modem and am doing VPN over it. There's a route needed for VPN added like this: ip route add 192.168.1.0/24 via 1.2.3.4 src 192.168.2.1 There are two problems with it: a) if ADSL link is down when above command is executed, the route

As I received no response on the general CentOS list, I'll repost it here as the question is about Xen virtual machine routing. This is my network setup: http://pastebin.com/kyWpTQYU Lets assume my dom0's eth2 public ip is 1.2.3.33 and my dmz network 11.22.33.96/255.255.255.224 . I have created NAT from my LAN with iptables. You can see my /etc/sysconfig/iptables here:

I''ve got 2.0.7 running on a machine with 1 physical interface and two bridges, like so -- bridge name bridge id STP enabled interfaces xen-br0 8000.0040f4ce392f no eth1 vif5.0 vif9.0 xenbr1 8000.feffffffffff no

I have a Xen DomU configuration that was made in the days before libvirt and virt-install. In this configuration I have: vif = [ ''mac=00:16:3e:05:06:01, bridge=xenbr0'', ''mac=00:16:3e:05:06:0a, bridge=xenbr1'' ] and then in xend-config.sxp I define (network-script my-network-bridge) where my-network-bridge is in the scripts directory and looks like this:

Hi, until now, i have been using Xen 3.0.2. Now i upgraded to Xen 3.0.4. Can anybody confirm, that the ordner in the config files for the network interfaces has not changed? My config file used to read: vif = [ ''bridge=xenbr0'', ''bridge=xenbr1'' ] So inside the DomU, eth0 was attached to xenbr0 on the host and eth1 was attached to xenbr1. Now i upgraded to

Hey All I''m Using Xen 3.0.3-105 on CentOS 5.5. It Has to Nics: eth0 - Internet eth1 - Internal Lan ( where Dhcp , DNs , Cobbler - Kick Start Server Resides ) I''ve Set xend-config.xsp to create xenbr1 on eth1 and it looks well So Guest May Get Access TO ALl Resources via the Bridge. brctl show bridge name bridge id STP enabled interfaces xenbr1

A number of weeks ago I had huge help from many of you configuring routing on a server with multiple Internet facing nics. Thanks for all of your help!!!! I am still having a routing issue that I am hoping someone can help me tweek. This server, besides acting as our gateway to the internet, is also our web and email server. The server has 4 nics. Two are connected to the internet and the

When I add all interfaces, the internet does not work.... eth0 = interneteth1 = lan ------------------auto eth0 iface eth0 inet static address 192.168.1.254 netmask 255.255.255.0 broadcast 192.168.1.255 auto eth1 iface eth1 inet static address 192.168.0.100 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.254 auto xenbr0 iface xenbr0 inet static

Hello, I am having a frustrating time trying to get bridge networking working. I''ve gone over the Wiki page on the topic, a few of the howtoforge pages and everything that I am doing is failing utterly. What I want to achieve is to have Dom0 be a stub running two DomUs. One DomU being a router/firewall and the other being the rest of what is on the current machine.

Hello, I''m new to Xen (and this mailing-list) and facing some problems with the network. I''m stuck and don''t know how to continue. And Google isn''t very helpful either... My setup: - Ubuntu 7.10 for dom0 and Debian 4.0 for all domU - 4 physical NIC (DHCP from my ISP, internal LAN, DMZ & WLAN) - 1 Dom as firewall/router - 1 domU with internal services
