Fedora Networking :: How To Assign Two IP Addresses To One NIC

Jul 29, 2009

I have connected my computer to network. Computers in network have dynamic ip address which is assigned by ADSL modem's DHCP. Besides this I want to have static IP address for same NIC. So is it possible to have both static and dynamic IP address for single NIC? If so how can I assign it using command and also in GUI?

Networking :: Dhcpd3 Doesn't Assign Proper Addresses To Vlan Subnets

Oct 22, 2009

I have dhcpd3 running but it does not seem to properly use my vlan subnets to assign addresses.

I have eth0.10, eth0.20, eth0.30, eth0.40, eth0 all declared with proper ranges, subnets and gateways.

If request an address in on eth0.30, I would think that it should use the range associated with this subnet (ie eth0.30 is 10.10.30.10/24) and this is setup in dhcpd3, but this is not the case.

It seems to use the first declared subnet instead. If I comment the first subnet out, it uses the second one properly.

Fedora Networking :: Get The Router To Assign An IP Address Through DHCP?

Jan 24, 2009

I noticed that my internet connection wasn't automatically brought up each time I logged into Fedora so I opened the system-config-network tool and edited my network adapter by checking the box marked "automatically start at boot/login." To my surprise, the connection went down and upon trying to click on the device to let the manager bring up the connection the greyed-out phrase "device not managed" appeared underneath the device name and wouldn't allow me to connect.

Even when I used ifconfig/dhclient to get the connection up nothing happened. I could get the router to assign an IP address through DHCP, pinged a few sites to make sure it was legit, but still couldn't use firefox to browse anything. Seems as if network manager GUI is conflicting with command line attempts to bring the network up. I'd like to permanently disable system-config-network if possible because it's acting screwy!

Fedora Networking :: Can't Access Internet With Web Addresses ?

Jul 7, 2010

I installed Fedora 13 on my laptop today after deleting a badly screwed up Windows XP partition. Everything installed smoothly even my Broadcom drivers but I can't seem to figure out how to get Firefox to access the web with a URL.

I can ping Google, and can get to it in Firefox if I use the IP address from the ping, but going to [url] in Firefox will give me an error message about not being able to find the server at the web address. I was also able to update from the terminal with yum update just fine. I've tried searching Google for some answers, and maybe I just can't phrase my query right, but I found nothing that I could use to try and fix my problem.

I've attached a HardInfo report which I hope could be useful if you need to know what my hardware is (an HP Pavilion zv5000 laptop).

Fedora Networking :: Configuring IPv6 (network) Tunnelling - Getting Only Internal Addresses From DHCP

Aug 25, 2011

I am trying to configure my IPv6 network. My computers are behind a Fedora gateway IPv6-configured, which is working great. But for computers inside my network, it seems I am getting only internal addresses from DHCP. Here is my ifconfig for an internal computer:

Networking :: Networking Routing \ Use The Terminal To Assign Server Eth0 A Proper IP Address?

Jun 8, 2010

i know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.

so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through

Networking :: Assign 2 Different IP's To 2 Different NICs?

Jun 17, 2010

My server has 2 network cards. I have SLES 10 SP2 installed on this server. I had configured Ethernet bonding on this machine using 2 NICs. Now I want to assign 2 different IP's to 2 different NICs. I am able to do this without any issue using yast. ifconfig command shows that eth0 has 192.168.1.10 and eth1 has 192.168.1.12. Rest all networking details are same (netmask, gateway, DNS)

Strange thing: When I unplug only eth0, (eth1 is plugged in correctly) I am not able to ping any IP.
If I unplug only eth1, (eth0 is plugged in) I am able to ping both IP's.

Networking :: Two IP Addresses Using One NIC?

Feb 10, 2010

Is it possible to configure two IP addresses using one NIC? I'm implementing a VPN server on network 192.168.1.0, ultimately to be accessed over the Internet and through an ADSL router with port-forwarding to the server. Right now I'd like to test it on the LAN, but with the VPN client and server both on the 192.168.1.0 network, that test would not be be valid.

If I had a spare NIC I could put the server on both the 192.168.1.0 network and, say, a 10.0.0.0 network, configure the client on 10.0.0.0 and test. Not having a spare NIC, I'm wondering if it is possible to configure the server with two IP addressese NIC.Virtualising hosts are able to do something similar when running guests with NICs in bridged mode. Log files show they switch eth0 into promiscuouse.In case it matters the server OS is Slackware 13.0.

I have set up a cloud (Ubuntu) environment in my test lad and it's working fine I am confused setting up the public IP in the production environment. The cloud instance will get only a Internal IP address ( Private) we cannot bind the Public Ip to the cloud instance as it uses Elastic IP, so I am confused how can I set up this if I have about 250 Public Ip to 250 cloud instance. How will I map this 250 Public IP with the 250 internal IPs is there any hardware device.

Ubuntu Networking :: How To Assign Labels With Ip / Ifconfig

Oct 19, 2010

I am trying to manually set up a number of static IPv6 addresses to one of the physical network interfaces on my 8.04server box.

I tried to use the "ip" utility like that:/ip addr add [myIPv6addr] dev eth0 label eth0:0

which was accepted by ip (no errors) and the IP address was correctly assigned to eth0. But using "ip addr show" I do not see any reference to the label I defined and "ip addr show dev eth0 label eth0:0" does not come back with anything (empty output).

This seems to contradict the information I found on the ip manpage and I wonder if this is a bug or a misconfiguration on my side. Did anyone successfully used the label functionality with ip?

Ubuntu Networking :: Can't Assign Specific Static Ip

May 25, 2011

Using Ubuntu Server maverick here - after altering /etc/network/interfaces to use a static ip and checking /etc/resolv.conf (no alteration needed) no network services were working at all. Here are the contents of interfaces:

Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
broadcast 192.168.1.0
gateway 192.168.1.254

I was fairly certain that this was verbatim from my previous server which is no longer attached to the network. After hours of fooling around with no success I changed the address to 192.168.1.99 and it worked perfectly. So my question is: why? My old server used 100. Could the router refuse to give a new server the same address or something like that since that address had been taken in the past?

Networking :: Assign Own IP Address On Ubuntu Desktop?

Jan 20, 2010

I am a certified newbie into linux. I am using now ubuntu 9.04. Now here is my question. Is it possible to assign your own IP address on your ubuntu desktop, I mean a fixed IP address? Because everytime I start my computer, my internet service provider will automatically assigned a NEW IP address to my computer, but when I'm on windows the ip address is fixed.

I've installed and configured lampp and joomla. I am trying to learn how to use the joomla under ubuntu using only my computer as my local host. But when I restart my computer, the IP Address that is assigned is different to what I used when I installed joomla so I cant access my website even if I am using the same computer when I installed it. Is it possible to assign a fixed IP Address to my computer under ubuntu.

Networking :: Assign An Alternate Ip Address On Same Lan Card

Jul 10, 2010

I am running Linux AS4 Update version. I have one lan card and the primary IP-Address is 192.168.0.215 & subnet is 255.255.255.0

Now I want to assign an alternative IP-Address on the same card & the IP I want to assign is 192.168.15.215.

I run the following command from root user:

Now when I ping this IP 192.168.15.215 From Windows machine then its reply me & properly reply comming from this Ip.

But when I want to access this Ip by \192.168.15.215 from run prompt then it gave me error. The specified network name is no longer available..

I already restart the machine & network service but the problem remains same.

Networking :: Assign A Private IP Address To The Same Interface?

May 15, 2011

I recently just upgraded from humble Linux user to confused Linux admin of my own virtual Linux server. When I issue the ifconfig command I get following output.

Code:

venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:1.2.3.4 P-t-P:1.2.3.4 Bcast:1.2.3.4 Mask:255.255.255.255
UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1

The WAN IP of the interface is not really 1.2.3.4 I just changed that IP for security reasons.What I am trying to figure out, is it possible to assign a private IP address to the same interface or can I only have one IP address per interface. I understand I have a mask of /32 so I am not going to be able to subnet the address to create any more addresses, so I assume I am stuck with the WAN IP (public IP) that I have, and just need to deal with it.

The reason I ask this is because I have been reading through several DNS/BIND tutorials/walk-throughs, and a lot of them specify setting up a intranet access with 192.168.1.1 address for the local DNS server, but since I am connecting to the sever via SSH I figure I do not need a private IP address.

Networking :: More Than One MAC Addresses On Single NIC?

Sep 25, 2010

My machine has ONE ethernet card and is on a LAN.IP address is assigned to hosts using DHCP.I can have more than one MAC address on LAN by running Virtual Machine and setting network to bridged. This way, my virtual machine simply acts like there is one more machine in the network.Running VMWare for this job is a a bit heavy on resources. Is there a way so that I can I can have 2 or more ip addresses with different MAC address on the same machine without having to run VirtualBox.

By googling, I think its related to bridging and tap. And, I am sure thatts NOT IP-ALIASING because in ip-aliasing both the ip addresses have the same MAC address.Basically, I want my system to have interfaces like:-eth0 - which was originally presentlo- thats always present :|newint0 - New interface with new MAC address and IP addresses which can access my LAN directly. Its like if I bind, let us suppose curl to this interface, its like a different connection

Networking :: How To Assign Eth0 To Server For Using Internet (DNS / Gateway)

Feb 14, 2009

Since I have a new internetaccount, 2 days ago, I have a problem on my server [Fedora Core 8]. I use it as a router.

eth0 is for the internet.
eth1 is for my LAN.

But since my new internetaccount my server uses eth1 for the internet. This is a line from my syslog:

Code:
NetworkManager: <info> Policy set 'System eth1' (eth1) as default for routing and DNS. I killed the NetworkManager daemon and now it works but this must not be the way to do it? Where do I tell my server that I use eth0 for routing and DNS?
