Ubuntu Networking :: Assign An IPv6 Address To Separate Users?
Apr 15, 2011I have an Ubuntu 10.04 server/router with IPv6 internet connectivity (I have an internet routable /64 subnet). Since I have this abundance of IPv6 addresses I wanted to try and assign v6 addresses to specific users on the local system. I've been looking at ip6tables with packet mangling but I don't seem to be able to find out how to do this or if this is even possible.
Current configuration: eth0: Local network, has the /64 IPv6 public range active and the IPv4 LAN range. tun0: 6in4 tunnel with a ISP assigned public v6 address. eth1: Standard IPv4 internet connection.
All users on my system use the v6 address configured on tun0. I want to force them to use the /64 range which is configured on eth0. If I can force users to use a specific v6 address, I'll configure more then one v6 address on this interface based on the users userID on the system.

Networking :: Unable To Get IPv6 Addresses Using Ioctl()
Feb 4, 2011I am able to retrieve IPv4 addresses with ioctl. But it is not returning IPv6 addresses. My requirement is to get both IPv4 and IPv6 addresses. I can not use getifaddrs() since it has to be common code between linux, solaris and aix. Solaris and AIX are not having getifaddrs(). Following code is returning only IPv4 addresses.
Code:
#include <sys/types.h>
#include <sys/socket.h>
#include <sys/ioctl.h>

Programming :: Ioctl TIOCMGET Call Doesn't Detect TIOCM_CTS
Apr 6, 2011I am having the following problem. The following code works fine on my P.C. Ubuntu x64, and on a jetway mini-itx board with an atom processor. The problem is, the same code doesn't work on the intel equivalent of the jetway board. I thought the maybe, I didn't have the port configured right, so I turned on Hardware Flow control and also tried turning on the modem bits I needed with TIOCMBIS. Neither worked. Here is the code. There are two threads, one of them, respsponding to the client, and using the RTS and DTR pins to power two relays. The other, manages listening to CTS and DSR for input. Here is the class with the first thread.

Fedora Networking :: FC15 IPV6 Wireless Router - No Longer Gets An IPv6 Address
Aug 31, 2011I have been struggling to get FC15 to act as an IPv6 router for a while now, am sure I am missing something trivial.. The idea is that I have a ppp / adsl connection (this works fine), use the wireless card on my pc with hostapd and dhcpd to provide connections to other pcs (works fine), and radvd to delegate ipv6 addresses.
The issue seem to be that as soon as I turn on ipv6 forwarding (net.ipv6.conf.all.forwarding =1), the ppp connection no longer gets an IPv6 address. This means the router cannot ping any ipv6 address outside my network.
If I disable ipv6 routing, my router gets an IPv6 address on its ppp connection, and can ping things such as ipv6.google.com just fine, however (of course) no packets are forwarded from my network and radvd complains that forwarding is disabled.

Feb 11, 2009I have installed Ubuntu 8.10 Server Edition on Virtual Box. When I start the virtual machine I do not have connection to my home network. The router I have does not assign any IP address to this machine. Now I have some questions which I am finding hard to find answers for over the internet and other forums.
If I do have a network interface (I checked this using ifconfig -a) then is there a command to actually make the operating system connect to that network (something like repair on windows)?? Also what is the difference between a network interface with alias eth0 and eth5? I know that when it was eth0 the virtual machine used to connect to the network automatically. Now that it is eth5 it does not! I do not know however if this is related.

Jul 4, 2011I want to modify ioctl TIOCMWAIT to return the same thing that ioctl TIOCMGET returns. Currently wait returns an int of zero or -1 when a change in status occurs. Why not make it return the new status?
This will make the operation faster by not requiring another call to ioctl.The extra call requires 2 to 16 uSeconds to complete on my x64 laptop. How would I make this proposal to the kernal people?

Jun 30, 2009I have a problem with my ipv6 connection: although I can't get ipv6 address with DHCP, I can't use ipv6 network. I tried [URL], and the tortoise is static. I want to fix it out , so I use 'ifconfig' to see my network configuration:
eth0 Link encap:Ethernet HWaddr 00:50:8d:ef:dd:06
inet addr:210.77.9.102 Bcast:210.77.11.255 Mask:255.255.252.0
inet6 addr: 2002:d24d:b64:4:250:8dff:feef:dd06/64 Scope:Global

Some people told me that the fisrt ipv6 address was wrong and unsuitable for ipv6 connecting. I tried /ect/init.d/networking restart but it didn't work. How can I use the second address as my ipv6 address and fix the problem out ? Now it seems there is not problem with the ip adress but the route. After watching some video, I suddenly could use ipv6. I did 'ifconfig' again and nothing was different. However, the result from the command 'ip -f inet6 route' changed: the last default route was gone and there was only one default route.

Networking :: Assign Own IP Address On Ubuntu Desktop?
Jan 20, 2010I 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.

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, 2010I 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, 2011I 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.
