[ubuntu] Trouble with simultaneous Ethernet for LAN and Ethernet for IP Camera

linux-howto

http://ubuntuforums.org – Hello, I am running ubuntu 12.04. I have a desktop that has two ethernet cards. I would like to use one ethernet port (eth 1) for SSH connections or connecting to a LAN to access the internet. The other ethernet port is to use an ethernet IP camera. I am having an issue where I can use SSH or the LAN on eth1 when I have the camera disconnected from eth0. I can also use the camera on eth0 only when I am disconnected on eth1. How can I run them simultaneously? I am not very knowledgeable with networking but the /etc/network/interfaces is setup like: auto eth0 iface eth0 inet st (Hardware)

Stories similar to [ubuntu] Trouble with simultaneous Ethernet for LAN and Ethernet for IP Camera

I've got a Ubuntu box with two network cards, the box is running motion to capture images from my ip security camera.

Hi all, I am trying to get 2 network cards working at the same time. The first is a motherboard nic and i have no issues with it, the second is a Linksys LNE100TX. What I want to be able to do is to have the motherboard one (Eth0) for internet access and the Linksys (Eth1) for loading software via ethernet.

I'm attempting to use NMap, however it appears to be incorrectly choosing my first ethernet interface, even thought that interface is in the down state.

C:\Windows\system32>nmap --iflist

hi all

I have searched google but no luck

I want to connecting using wireless card (wlan0) and using ethernet at the same time (eth0) at the same time NOTE: there are two different connections (networks)

my network manager is wcid , it only connects ether wireless or ethernet not both

I want to have two IPs at the same time

I want to use my desktop with a wired ethernet connection (eth0) to operate my USB Wifi Adapter (wlan0) as a non-adhoc access point (so my android can connect to it).

After MUCH searching, I finally found a method that works with about 95% of what I want.

I modified "/etc/network/interfaces" to contain:

auto lo iface lo inet loopback

auto eth0 iface eth0 inet manual

auto br0 iface br0 i

I've setup Ubuntu server along with ufw as a firewall.

To start, I have two networks:

Public: 66.xxx.xxx.70 - 66.xxx.xxx.78

Private: 192.168.3.1 - 192.168.3.255

My network config:

auto eth0 iface eth0 inet static address 66.xxx.xxx.70 netmask 255.255.255.0 network 66.xxx.xxx.0 broadcast 66.xxx.xxx.255 gateway 66.xxx.xxx.1

auto eth0:0 iface eth0:0 inet

I can't ifdown an interface on a Debian 6.0.5 box;

user@box:/etc/network$ sudo ifdown eth0 && sudo ifup eth0 ifdown: interface eth0 not configured SIOCADDRT: File exists Failed to bring up eth0.

user@box:/etc/network$ cat interfaces auto lo iface lo inet loopback

allow-hotplug eth0 allow-hotplug eth1

auto eth0 iface eth0 inet static address 10.0.0.1 netmask 255.255.255.0 gateway 10.

Hello everyone. I have a VPN I use for various things. I connect to it using NetworkManager, so when I want to use it I currently have to use it for all my internet activities. I'm wondering if there's a way for me to have 2 ethernet devices, like eth0 and eth1, so that I can connect one to the VPN and the other can stay as is.

I love Ubuntu but so far a lot of the network devices I've tried have been nothing but problems. I'm adding a second NIC to my Karmic 9.10 desktop. It's been 2 weeks and I've tried 2 other cards already with no luck.
