Laboratorios-IPv6

Type the following two commands: >>> a=IPv6() >>> a <IPv6 |>. IPv6(). a.

You can change the value of specific fields of the IPv6 header: >>> a.dst="2001:db8:a:b::123:321:101" >>> a.src="2001:db8:1::a101" >>> a.show() ###[ IPv6 ]### version= 6 tc= 0 fl= 0 plen= None nh= No Next Header hlim= 64 src= 2001:db8:1::a101 dst= 2001:db8:a:b:0:123:321:101. To do this, you can use the variable name, __ dot “.”, and the name of the field. For example, for your packet a, you can change the destination address. For example, for your packet a, you can change the source address.

These commands show: ans.show():. ans[0]:. ans[0][1]:. ans[0][0].show():.

Wrapping up & lessons learned You learned the basics of Scapy, a tool to generate tailor-made packets. You now know what you can do with these functions in Scapy: IPv6(). show(). ICMPv6ND_NA(). ICMPv6EchoRequest(). help(). send(). sr(). srloop(). sniff().

Find IPv6 addresses in the link using the scanning tool from THC-IPV6 THC-IPv6 has a tool for scanning a link called alive6. To use it, you just need to specify the interface where you want the tool to scan. alive6 eth0. alive6 eth0 -vv. alive6 eth0 -M 2001:db8:f:1:216:3eff:feee:a-c.

Below you will find two examples of Message Body content for the following errors: Packet too big NOTE: This is using the General Format for ICMPv6. Message Body:. Parameter problem NOTE: This is using the General Format for ICMPv6. Message Body:.

Neighbor Discovery Protocol (NDP) Link Monitoring tools. 6MoNPlus. NDPmon. 6Guard. RAMOND. None. All.

Switches should understand Ethernet, IPv6 and ICMPv6 to be able to configure proper filters. In the Ethernet header, it should understand the Ethertype corresponding to IPv6 (0x86DD), and also the source and destination MAC address used in Ethernet. In the IPv6 header, it should understand the version (always 6 for IPv6), the source and destination IPv6 addresses, and also the next header value. In the ICMPv6 part of the packet, it should understand or be able to filter the different types and codes within each type. This allows fine granularity when it comes to filtering.
