Suppose I have both a hardwired and a wireless network connection active on the same system at the same time. Can I tell my browser which one to use? Can I tell other programs which one to use? Or do they choose for themselves> Or does some automatic system protocol select which one to use for them?

If I comment those off then no such problem, hence some how ppp0 executed automatically and there is no [auto ppp0] any where. How can I stop this forcefully ?

How can i route from eth2 (10.x.x.x) to (eth1 or br0 (80.109.145.x) to Modem (80.109.145.1)?
This past Friday as I was performing regular maintenance on my RHEL / CentOS servers, I ran yum upgrades on them and when they rebooted, I realized there were network issues and I could not longer access them via Ping or SSH. When I jumped on the console, I realized that it created a new 'ifcfg-eth0' file with none of my static information & the old 'ifcfg-eth0' file with all my static info had been renamed to 'ifcfg-eth0.bak'. It appears that the MAC address on the new file and the old .bak file are different and I have no idea why. I have no changed or altered anything on the server.

This configuration is done by doing the following operation sequences(System->Preferences->Network Connections->wired->auto eth0). Then I can connect to and browse the internet.

From what I can understand I'm able to create aliases by adding entries to /etc/networks/interfaces, I haven't tried I'm in the planning stages. Hypothetically, 192.168.22.30 is my primary IP and I want to set eth0:1 to have 192.168.22.31, and then after that I want to create a virtual machine (using kvm/qemu) that is able to communicate bidirectionally to the internet over eth0:1, and leave eth0 strictly for administrating (not for VM traffic).
The qemu guides I'm finding seem to assume that I want to use TAP or VDE, what I want to use is a sub-ip/alias. One guide I saw had me eliminate everything from eth0 and put it under br0. That would leave me unable to ssh into my server (and unable to administrate). Is there a way I can do something along the lines of: qemu [options] -net [option] -netdev=eth0:1 ?
Is is possible, via iptables or something similar, to bind a service running on a specific port to a specific interface? My case: I use a VPN service for privacy. I would like to have all traffic except ftp and ssh to run over tun0. Ports 21 and 22 will need to be accessible to the outside world (eth0) while the VPN is running.

I am having some troubles using iptable rules on two Servers that act as Gateways pointed to one backend server with only one interface.
To be more exact, i have 3 Servers, 2 of those have a public and a private interface, with different public ips but common private interface ( they connect to the same switch ), the last one only has 1 private interface and is connected to that same switch.
Those 2 servers also act as a gateway and a firewall for the private network.
My problem is that i cannot seem able to route traffic from both of those to the third one and back to the same public ip that the request came from ( effectivly using two gateways on the machine with only one interface ).
As a testing scenario i am using ferm for applying iptable rules that forward ssh traffic ( for example ) to the backend server, and it works well when i do it with one gateway.
When i apply something like this in /etc/network/interfaces on the backend server though:
Code: Select allauto eth0:0 eth0:1
# The primary network interface
allow-hotplug eth0
iface eth0:1 inet static
address 192.168.9X.XXX
netmask 255.255.255.0
broadcast 192.168.9X.255
network 192.168.9X.0
[Code] ....
Even though forcing selection of an interface from the backend server ( like curl --interface ) seems to work well, meaning that the request to the curl appear to happen from the correct public ip, i can still only use one of the public ips to access the server with the ferm rules. Ideally i should be able to ssh to the backend server from both public ips using their ferm rules for forwarding traffic to the backend server.
I feel like i am missing some details on routing that should happen on the firewalls as the backend server seems to be able to use both gateways to access the internet and receive replies from it.
I tried installing the driver following the instructions in the link given below.

View 14 Replies View RelatedI am running Debian Squeeze on an old pc (AMD K62-500) which serves as my multiwan router and torrent box. Internet uplink is provided via a dsl line and 2 wireless canopy modules.
Setup has been generally fine except when connecting/downloading as free user from sites like rapidshare, hotfile, filesonic, etc. The problem arises when I am connected to these sites using the wireless uplinks because of the shared public ip. I don't really download that much using direct download methods so I don't really see myself being a premium user from these sites.
If these sites are on a specific ip or ip range, an entry on the static routing table would have been fine but when I tried using ping, a different ip would appear to reply each time.
I wonder if there can be a solution like using iptables where in traffic to and from these sites will only use the NIC connected to the dsl line.
I want to configure multiple virtual ethernet interfaces over a single physical ethernet interface (eth0) and for each virtual interface the MAC address must be unique and the IP address must be Static.Finally all the virtual interfaces must be able to communicate both internally and externally and the traffic should be captured using wireshark.
I need to have such kind of setup to communicate devices individually using one physical ethernet device.
Because I was fiddling with few kernel modules like MACVLAN and MACVTAP and successfully enabled those modules and rebuild kernel. Using macvlan and macvtap I can configure virtual interfaces with unique mac address and static IPs but while capturing packets using wireshark interfaces behave weirdly.
For example say on HOST machine I have 1 physical interface and created 3 virtual interfaces as shown below.
Interfaces :
eth0 (physical ethernet interface)
IP: 192.168.A.A
MAC: aa:aa:aa:aa:aa:aa
[Code] ....
First from above interfaces I started pinging eth0 internally from host machine in which it worked as usually.
Second I did same externally from other machine which is connected to the same network of Host machine, and this did work as usually.
Third I pinged first virtual interface veth0 both internally and externally and this also works and after that I did check source and destination MAC address using wireshark tool-where both showed up there respective MAC address.
Now triggers the issue, where I pinged second virtual interface same like I did for first one, but this time ping was success and where as in wireshark tool the MAC address for veth0 is picked by veth1. This is where I got stuck and this issue happened for all the remaining virtual interfaces.
I couldn't see any virtual interface showing their respective MAC address, as of the remaining except the first virtual interface has been picking the first veth0 mac address.
I have been trying to get my wireless interface work but i am unable to find a driver for the wireless interface.

I'm having difficulty setting up my desired network infrastructure. Here's the situation:
I'm currently using an Ubuntu box as homeserver to do everything from sharing internet (via NAT), over DHCP & DNS to filesharing and even virtualisation.
However, since my machine is capable of virtualising Astaro Security Gateway properly, I would like to transfer and split up responsibilities.
I want to have my Astaro fully responsible for the internet and act as the gateway, and along with that disconnect my physical box from the internet and put it behind Astaro (basically making it just a member of the internal network).
The difficulty I'm having with this is that Astaro is running virtually on the physical box, and I can't seem to figure out how to configure the external interface. It needs to be up for Astaro to be able to use it, but it should not give the physical machine access to the external network.
I'm thinking I could set it to manual and not give it an ip address, but I'm not sure on this.

The "System Settings/Startup Programs" window is large enough but the "Program" column is too narrow and it cannot be resized. The window can be dragged to make it larger but not the individual columns. It looks like a Java listbox with "Enabled = false" set. This occurs in Debian8 64 bit and also in Mint 17 and Mint LMDE2. I am surprised nobody else has raised the issue. I have a basic setup with 22" screen and 1680 x 1050 resolution. It occurs with Nouveau and NVidia drivers. It is not a critical bug so I have coped with it for 2 years but it would be nice to see it fixed. Unfortunately I could not upload a screen shot as "board attachment quota has been reached".
