Proxmox and Centos 6.3 NETWORK DON'T WORK :'(

https://www.centos.org – Hello and welcome to the fora.I would think your network setup is wrong. Your netmask reads 255.255.255.255 which kind of makes it hard for the host to reach a default gateway. [by tigalch] (HowTos)

Bonding - 2 Devices failed 9 weeks 2 days ago

i have a Linux Server - Setup with Proxmox 2.3 (ISO-Installer). I tried to update the Installation and so i got a Problem because I have to Links and must configure a bond.

We have 10.0.0.0 private network. I connect to network via wifi and get 10.103.7.xxx ip address, 255.255.255.128 netmask and gw 10.103.7.129. The problem is that we share internet connection through gateway 10.103.6.36. I can ping this host, but I can't set 10.103.6.36 as default route. I'm getting "no such process".

There is a class B ip, like x.x.62.162, netmask is 255.255.255.192 , gateway is x.x.72.62. As usual, i put it into /etc/sysconfig/network-scripts/ifcfg-eth0, and restart network. It doesn't work. But, the other Windows desktop works fine with it.

Is anything that i missed? could anyone help me, thanks a lot.

I'm trying to enable IPv6 on my Debian nodes (OpenVZ) using venet; my host is under Proxmox 2.2 (kernel 2.6.32-16-pve), and it seems the routing fails.

My host correctly pings all my nodes; all my nodes ping my host, but none of the nodes can ping another node or the outside world.

Can't ping gateway after bridge 34 weeks 3 hours ago

I am running CentOS 6.3 with NetworkManager disabled.

I was trying to set up a network bridge to try out setting up guests w/ kvm. I was creating a bridge before setting up stuff with kvm, just since I wasn't too familiar with it. Something didn't go right and I couldn't ping the gateway ip or anything past it with the bridge in place. The ip, netmask, and gateway are all correct.

So here's the scenario: Network A is the physical network (10.1.1.x 255.0.0.0) which is connected to the internet via the gateway at 10.1.1.1. Network B is a 'virtual' (VMWare Workstation) network using the IP range 172.16.0.0 255.255.255.0 and the VMware DHCP server.

The goal is to create a virtualized network on Network B that can be routed to directly from Network A, but only through a virtual

So this has been driving me nuts for a good couple of hours, so I thought I'd ask about it here (let me know if there's a better forum for this question).

I have a CentOS Virtual Machine on ESXi. I was trying to configure the network interface because it wasn't working, so I changed the file /etc/sysconfig/network-scripts/ifcfg-eth0 to the right IP address/gateway/netmask/MAC ID etc.

I've read quite a few articles now, and they all pretty much say the same thing.

I've set up a virtual lab network in vmware with two network.
