Hej alle,
Først vil jeg vide lidt om IPv6.
Jeg har to mål. A og B, A og B connet med hinanden * direkte * med line.and jeg kan pinge hinanden med ipv4
For A:
PHP Code:
[root@localhost leilyang]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:21:9B:80:51:68
inet addr:128.224.159.188 Bcast:128.224.159.255 Mask:255.255.254.0

For B:
PHP Code:

På A, I ping6 2002:1:: 2, men undlader at ping.
På B. jeg køre
PHP Code:
root@localhost:/netperf_image> tcpdump -n ip6
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
