※ 引述《Paranoid (Gentoo 萬歲 !!)》之銘言：真不好意思又要麻煩您了~~~~ : 同時 tcpdump 您的 linux router 和 client 。 : 1. 在 client 跑 tcpdump (只聽 ipv6 即可) : 2. 在 router 跑 tcpdump (只聽 ipv6 即可) : 3. 在 client 跑 ping6 <IPv6 address> (跑久一點, 比較好看結果) 我照您的做了！ client's packet: Frame 1 (94 on wire, 94 captured) Arrival Time: Nov 2, 2003 02:02:05.492085000 Time delta from previous packet: 0.000000000 seconds Time relative to first packet: 0.000000000 seconds Frame Number: 1 Packet Length: 94 bytes Capture Length: 94 bytes Ethernet II Destination: 00:04:e2:02:93:44 (SMC_02:93:44) Source: 00:02:a5:a8:12:0a (Compaq_a8:12:0a) Type: IPv6 (0x86dd) Internet Protocol Version 6 Version: 6 Traffic class: 0x00 Flowlabel: 0x00000 Payload length: 40 Next header: ICMPv6 (0x3a) Hop limit: 64 Source address: 3ffe:3600:1c:9c00:202:a5ff:fea8:120a Destination address: 3ffe:3600:1e::4bb Internet Control Message Protocol v6 Type: 128 (Echo request) Code: 0 Checksum: 0x8ebf (correct) ID: 0x0000 Sequence: 0x0093 Data (32 bytes) Frame 2 (142 on wire, 142 captured) Arrival Time: Nov 2, 2003 02:02:05.492666000 Time delta from previous packet: 0.000581000 seconds Time relative to first packet: 0.000581000 seconds Frame Number: 2 Packet Length: 142 bytes Capture Length: 142 bytes Ethernet II Destination: 00:02:a5:a8:12:0a (Compaq_a8:12:0a) Source: 00:04:e2:02:93:44 (SMC_02:93:44) Type: IPv6 (0x86dd) Internet Protocol Version 6 Version: 6 Traffic class: 0x00 Flowlabel: 0x00000 Payload length: 88 Next header: ICMPv6 (0x3a) Hop limit: 64 Source address: 3ffe:3600:1e::353 Destination address: 3ffe:3600:1c:9c00:202:a5ff:fea8:120a Internet Control Message Protocol v6 Type: 1 (Unreachable) Code: 3 (Address unreachable) Checksum: 0x2025 (correct) Internet Protocol Version 6 Version: 6 Traffic class: 0x00 Flowlabel: 0x00000 Payload length: 40 Next header: ICMPv6 (0x3a) Hop limit: 64 Source address: 3ffe:3600:1c:9c00:202:a5ff:fea8:120a Destination address: 3ffe:3600:1e::4bb Internet Control Message Protocol v6 Type: 128 (Echo request) Code: 0 Checksum: 0x8ebf (correct) ID: 0x0000 Sequence: 0x0093 Data (32 bytes) 而router 的 eth0卻沒抓到！那eth1的話就是跟client抓到的一樣所以跟本沒送出去，所以是router的問題~~~~~~ 前一篇我說的protocol=0x29這是v4夾帶出去v6時所定的, 在rfc2839有提到。這樣的結果應該是跟routing有關吧？ ping6 3ffe:3600:1e::352的封包是正常的，有傳出去。回來時hot limit=63。我用的是redhat8.0有差嗎？您之前用的是redhat還是？ -- ※ Origin: 銘傳資工神話站 <bbs.csie.mcu.edu.tw> ※ From : sw59-130-105.adsl.seed.net.tw
