I have three 10Gb Fibre PCI ethernet cards and 2 onboard gigabit ports. The two gigabit ports always seem to be mapped to eth0 and eth1. I set the network configuration for eth2, eth3, and eth4 in the /etc/sysconfig/network-scripts/ifcfg-eth# files. Would the NIC in PCI slot 1 always be mapped to eth2, NIC in slot 2 mapped to eth3, and NIC in slot 3 always mapped to eth4?

I have a peer-to-peer network with 25 WinXP Pro computers. I have built a Linux (SuSE) server for the purpose of backing up My Documents, PST files and favourites. Each user has their own folder containing the sync'd files. Each folder is password protected. I have configured each users machine with a mapped 'S' drive, which is the sync'd data folder on the Linux computer. All of the computers seem to end up with a "disconnected network drive" status after either logging out for the day or after some time has elapsed. Some will connect with a double click but others prompt for a password. I have tried mapping the drive using the option "Connect using a different user name", which is fine until the user logs out and back in again. I use SyncToy as a scheduled task, but can't connect to these mapped drives automatically, so the sync process will not work unattended.
View 3 Replies View RelatedI'm going to come right out and say I am a complete novice with Linux/SUSE. The equipment I'm having a problem with is a little web-server that was purchased by my employer that has, quite suddenly, stopped functioning. I was changing the IP address within YaST, at which point the device offered to update itself, which I saw no harm in. Post-update, however, I was unable to so much as ping the device.
I tried "ifconfig eth0": "Error fetching interface information: Device not found." I went into network settings via YaST and found that there are two cards now listed as: RTL8111/8168B PCI Express Gigabit Ethernet controller Both IP addresses are "Not configured". The information pane, for both cards, cites:
RTL8111/8168B PCI Express Gigabit Ethernet controllerBusID : 0000:02:00.0 Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details. The only difference in either of the cards is the BusID (0000:02:00.0 and 0000:03.00.0)
I can neither edit nor delete either of these cards. As I mentioned, I am a total Linux novice, and am at a total loss for what to do next, or even how to find critical information about the system itself. I know enough to check dmesg, but not enough to have any clue what to look for in the output.
create a profile settings and network drive can be mapped automatically when user login to the (like Domain and active user profile on windows environment) Ubuntu systems?

View 9 Replies View RelatedI have a media center set up on my home network with two NICs. Each NIC has been assigned a static IP:
eth0 192.168.0.254
eth1 192.168.1.253
Currently eth0 does everything network related and eth1 just sits idle. This computer also serves as my home server using NFS.
The NFS server and clients are already set up using eth0, so I'd like to set up eth0 to only handle LAN traffic and eth1 to only handle WAN traffic. This way, if I have bit-torrent or something running (using WAN), bandwidth within the LAN should be relatively unaffected.

Im using VirtualBox to run VMs and want to use NIC2 for the VMs exclusively and I want the VMs on a different network completely from the host.Ive tried setting up NIC2 on the other network but I end up with networking problems on network1. Also I cant figure out how to tell VirtualBox to bind to the host NIC2.
View 2 Replies View RelatedI have 2 x PCs and a NAS. Both PCs have 2x NICS. PC connectivity to Internet is via an ADSL router. Current config: Thus far (by choice) I've used static IPs in the 192.168.168.x range for my internal network, connecting all PCs and NAS via a jumbo frame enabled gigabit switch. This has facilitated moving data between the PCs and the NAS at high-speed. As both PCs also required Internet access from time to time, both are also connected to the ADSL router using the 2nd NIC and using subnet 192.168.1.x. I'm sure some of you are shaking your heads by now, but it works well and has been entirely hassle free.
However, I've an app running on the NAS that I'm keen to get Internet connected also. As my existing network devices are not using DHCP I figured the simplest method would be to change my ADSL router configuration such that it is in the same 192.168.168.x subnet, change its DHCP server settings to serve IPs in the same subnet (but in a restricted range I know won't cause any conflicts with the static IPs) and problem solved. On changing the ADSL router confiruration with all machines already booted up and configured as described above, everything worked. All devices could see one another, and access the Internet. On later rebooting the system this no longer works
- Internet access is fine but PCs don't see one another or the NAS. If I disconnect the ADSL Router from the PCs then all devices see one another again.
- Does having 2x NICS on a single device each assigned unique IPs in the same subnet create an issue and can it be overcome? I'd like to overcome it because making one of my PCs the gateway forces me to have it on anytime another device needs access.
- If I'm forced to use Internet connection sharing with one PC on the network connected to the router, how do I best configure this?
- One of the things I need to retain is gigabit connectivity between the PCs and PCs and the NAS (currently achieved by 192.168.168.x subnet being linked via gigabit switch).
My brother has a Ubuntu server attached to a LAN with Windows PCs. I set up an openVPN tun service on the server, let's call this VPN1, so that I can connect remotely from my Ubuntu desktop. The server has one NIC and the LAN has a router that is the gateway to the internet.
My brother would like to remotely access his windows network when roaming with his Windows laptop.
Therefore, I would like to set up a second VPN service, this time tap, that is bridged with his LAN. Let's call this VPN2.
The LAN subnet is 192.168.1.0/24. The internet gateway is 192.168.1.1
The NIC has a fixed IP set by the router of 192.168.1.150
How do I set up VPN2 so as not to trash VPN1? That is, if I bridge eth0 with tap0 how will that impact VPN1's tun0 that is using eth0? Do I need a separate NIC for the VPN2 bridge?
I am considering moving to a software (ebox/pfSense/Zeroshell etc) based router.
It fits well to have 1 NIC connecting to your modem & the other to your switch & network. It seems to make sense it is more secure, but is it?
If I assign the 1 NIC in my router 2 IPs, a subnet for the modem and a subnet for the LAN, how is the different?
I can't think exactly what it is. I am no network guru and probably missing something down at a lower networking level, but for a home router, does 1 or 2 NICs make any difference?
I have a pc with debian 6 (without GUI) installed on it and want to use it as server at home. It has 2 ethernet nics. Now i want to configure the routing process. Searched internet for a long time found something but couldn't get it work.

My PC has 2 NICs Eth0 has 3 virtual NICs:
My every PC (172.16.1.1 to 172.16.1.4) has installed webmin and listen on port 10000
When browse from LAN http://202.1.2.3:10000 .. it goes to the webmin page of 202.1.2.1 .. why?
This problem ONLY occurs when browse the site from LAN! and it works properly if we access it from Internet.
Ok so I'm gonna try and explain this easily. I installed 11.04 32bit on an older HP P4 machine. Boots up and goes to classic desktop.. But networking looks like a wifi devices rather than a wired connection. I installed another NIC rather than the onboard but had the same result.. I also tried yet another PCI NIC and a USB NIC with the same result. I also tried to set my connection to manual and give myself a static IP, but had no such luck.
I know my internet connection works because I'm on another machine typing this to you all.. All the NICs also work in W7 on the dualboot setup I did.
I have 2 NICs on my ubuntu server.... eth0 has its IP address....but eth1 doesnt.
How do I assign an IP address to eth1 using only commands on the command line?
And I need it to be permanently...
I have a MB with 2 NICs and on 1 I would like to have a static IP, on the other a DHCP for a local network.The problem is the DHCP provided gateway is made default vs the one for the static IP and resolv.conf is overwritten.Any suggestions how could this be resolved? I can tweak both the DHCP server settings and the box settings.
View 14 Replies View RelatedI have two NIC's interfaces on my linux machine(eth1 and eth2). Each have different IP addresses(10.0.0.1, 10.67.7.1). These two interfaces are connected together through hub. Here is the my question?
1) If I 'ping 10.0.0.1', it should go out through network interface eth2 and through hub and enter on eth1 and response also travel through similar direction.
2) If I 'ping 10.67.7.1', it should go out through network interface eth1 and through hub and enter on eth2.
How can setup routing table for this,I have tried setting up routing and iptables, etc.. nothing helped.
If any one good router/networking guy, you should know this one.I am doing a project, I want this way to handle this.
I'm trying to work out how to route all traffic destined for the internet from all devices connected to eth0 to a wireless router access point via wlan0 on my Slackware box. I also have dhcpd providing ip addresses on the same subnet to any device connected to both eth0 and wlan0.
Diagram:
Code:

192.168.2.253| Server |192.168.2.254

If I connect to the router/access point via wireless or directly to the Server via a crossover cable I can obtain an ip address from dhcpd, so that works. As far as I can see I just need to how to route between eth0 and wlan0 then I can provide internet access to those devices!

How can I make it so that Samba is accessible by name when I switch between interfaces?

I'm running 2 asterisk box (Centos) ,and the two servers are connected through 2 iax trunks.on one server i have 2 nics ,each one is connected to internet,now i want to use isp 1 for the first trunk and isp 2 for the second trunk.
iax 1 is listening on 12345
iax 2 is listening on 11223
is there a way to split traffic on both nic using ports (netfilter iptables)?
I have a server that provides the access to the net. It has 3 nics 2 Realtek 100mb and a ne2000 isa 10mb card for the net. I ran an update from a working configuration on Fedora 9 to Fedora 10 with yum upgrade. Fedora 10 does not find the the ne2000 at boot time. After booting I can modprobe ne and the nic is found in a new network restart call. Has something changed how modules are loaded before udev runs?
Then there is the problem that nics are assigned the wrong interfaces(eth*). I have configured it in sysconfig with the files ifcfg-eth(0-2). I do not run NetworkManager. Has something changed in the configuration how the interfaces are assigned to the nics via the mac addresses?
I have tried to change the net profile of udev but since the ne2000 is not found at boot time but had no success. And one of the Realtek nics is not found at some times.
I'm using Fedora 12 on a box with 2 separate NICs in different subnets. The problem is that after a reboot, both NICs always show up as eth0 when you left click on the networking icon on the top right. I have to manually change one of them to eth1 & then things start working.
DEVICE=eth0
HWADDR=(mac address)
BOOTPROTO=none

I'm trying to setup a Centos box to act as a backup server for our intranet between stores. I have two interfaces in it, the first one is currently connected to my local network and is using dhcp to get its ip address and such, the second one is set to a static ip address and is connected to an independent network that just has a DigiBoard Portserver hooked to it and no connection to the regular network. What I am doing is using ssh to portforward the telnet port on this box to the main server so when you telnet into the box from the second interface using the portserver you get connected to the main server.
I plan on using this over DSL lines as a backup when our main dervice goes out to allow the portservers at the remote locations to seemlessly connect to the main server by just moving the network cable from the local net to the backup server. My problem is that when I have the everything working I am able to ping the second interface ip address from the normal network even though the secondary card does not in anyway externally connect to the network, this is a problem.
Eventually I want to duplicate the main server address so that the normal portservers and other terminals on the remote site will not have to be reconfigured to access the backup server. All I want is to be able to tell the managers is to switch a cable while the main connection is down and not have to manage a bunch of config files to get the store back up. Right now if I duplicate the main server ip address and it is accessible through the first interface I'm guessing I'll see all kinds of problems relating to duplicate ip addresses on the network. I've tried some routing and iptable stuff but I'm not real familiar with either so I had no luck. Is there someway to block the internal connection between the two interfaces so the only thing that sees the duplicate ip address is the second interface?
I am really bothered from this I cant configure the 2 nics to share the internet and I already changed the sysctl.conf file to
# Controls IP packet forwarding
net.ipv4.ip_forward = 1
I have one nic reeving the internet and working good and the other one cant see anything...
I have been looking for a solution for this but am not certain how to word it to get a viable answer.My scenario:
Athena
Win7/Ubuntu 11.04
eth0 10.11.12.100/16 gateway+dns: 10.11.12.1
[code]....
I have a Debian 5 system with two nics. eth0 is set up with dhcp-client which will receive a public ip address from my isp. The eth1 will be for my local network and I want to use dhcp-server daemon to serve addresses to my internal network. The area I am confused about is how transmissions are getting sent between nics. I've been told to enable tcp forwarding but I don't understand how that would work since the nics have different network addresses... unless tcp forwarding is basically nat or something..
