Assuming only the traffic (which is destined to a contiguous address IPv6 block say a /64) reaches an interface (physical or virtual) by means of routing and/or filtering rules. The original question remains.
BTW: I know both BSD and Linux have ways of assigning IPs to an interface.
Let's stick with Linux for now.
I have a block of IPv6 addresess (say 1111::/64) that I routed and filtered such that only these addresses hit eth0.
then I know I can for instance say
Code:
ip addr add 1111::1/64 dev eth0
ip addr add 1111::2/64 dev eth0
and so on up to
Code:
ip addr add 1111::ffff:ffff:ffff:fffe dev eth0
which I believe it becomes unmanageable hence the original question.
Any other suggestion or hints besides using a raw socket and implementing my own stack which is doable but I do not really want to reinvent the wheel since all that is already in the kernel.
I know there is a function inet_tpon for unix platforms to validate ipv6 addresses.But i need an equivalent of windows.When i use this function with the header file <winsock2.h> the visual studio 2005 on win2003 issues an error saying identifier not found

I m having interface ce0 ce1 and its sub interfaces for that.
I want to give MAC addresses for the same.
How will I assign it.
Please give solution for the same (4 Replies)
Hi ,
by default the physical interface (eth1) and virtual interface eth1:0 will be having same mac address, is there any way we can assign separate mac addresses for both the interfaces.
would some one help me out in this.
Thanks

Hi,
inspired by this article, I decided to implement IPMP + IPv6 in Solaris 10.
It worked for me only this way:
1. Setup
# cat /etc/hostname*
10.23.10.113/24 broadcast + group data failover up <- hostname.e1000g0
0.0.0.0/24 broadcast + group data -failover deprecated up standby... (3 Replies)

Hi,
Am using FreeBSD7.4/i386
During IPv6 configuration, I added the following in rc.conf as

Hi All,
Would anyone know how to modify the below, so only the IPv6 address (red) is printed, please?
(in other words, what's between inet6 and the / sign)
ipv6=`/sbin/ifconfig lo0:5 inet6 | grep 'inet6'`
print $ipv6
Currently the output of the above script is:

tc-mirred
Mirror/redirect action in tc(8) Linux Mirror/redirect action in tc(8)NAME
mirred - mirror/redirect action
SYNOPSIS
tc ... action mirred DIRECTION ACTION [ index INDEX ] dev DEVICENAME
DIRECTION := { ingress | egress }
ACTION := { mirror | redirect }
DESCRIPTION
The mirred action allows packet mirroring (copying) or redirecting (stealing) the packet it receives. Mirroring is what is sometimes
referred to as Switch Port Analyzer (SPAN) and is commonly used to analyze and/or debug flows.
OPTIONS
ingress
egress Specify the direction in which the packet shall appear on the destination interface.
mirror
redirect
Define whether the packet should be copied (mirror) or moved (redirect) to the destination interface.
index INDEX
Assign a unique ID to this action instead of letting the kernel choose one automatically. INDEX is a 32bit unsigned integer greater
than zero.
dev DEVICENAME
Specify the network interface to redirect or mirror to.
EXAMPLES
Limit ingress bandwidth on eth0 to 1mbit/s, redirect exceeding traffic to lo for debugging purposes:
# tc qdisc add dev eth0 handle ffff: ingress
# tc filter add dev eth0 parent ffff: u32
match u32 0 0
action police rate 1mbit burst 100k conform-exceed pipe
action mirred egress redirect dev lo
Mirror all incoming ICMP packets on eth0 to a dummy interface for examination with e.g. tcpdump:
# ip link add dummy0 type dummy
# ip link set dummy0 up
# tc qdisc add dev eth0 handle ffff: ingress
# tc filter add dev eth0 parent ffff: protocol ip
u32 match ip protocol 1 0xff
action mirred egress mirror dev dummy0
Using an ifb interface, it is possible to send ingress traffic through an instance of sfq:
# modprobe ifb
# ip link set ifb0 up
# tc qdisc add dev ifb0 root sfq
# tc qdisc add dev eth0 handle ffff: ingress
# tc filter add dev eth0 parent ffff: u32
match u32 0 0
action mirred egress redirect dev ifb0
