Hi i have some problems with my tunnel, i made this script on a redhat 9.0A because the other explained on sixxs doesn't work. #!/bin/sh /sbin/insmod ipv6 /sbin/iptunnel add sixxs mode sit local 82.189.123.20 remote 213.254.12.34 ttl 64 /sbin/ifconfig sixxs up /sbin/route -A inet6 add 2000::/3 /sbin/ifconfig sixxs add 2001:1418:100:1f::2/64 traceroute doesn't work anymore and i can't ping any other ipv6 then my POP Example of a ping : PING www.kame.net(orange.kame.net) 56 data bytes From localhost icmp_seq=1 Destination unreachable: Address unreachable From localhost icmp_seq=2 Destination unreachable: Address unreachable From localhost icmp_seq=3 Destination unreachable: Address unreachable --- www.kame.net ping statistics --- 5 packets transmitted, 0 received, +3 errors, 100% packet loss, time 4339ms Example of a traceroute [root@laurouter rc.d]# traceroute6 www.kame.net traceroute: bind sending socket: Invalid argument It's a bit strange... isn't it? Then i've aked to my friend to traceroute my ipv6 and the result was this : traceroute to 2001:1418:100:1f::2 (2001:1418:100:1f::2) from 2001:6b8:0:400::282c, 30 hops max, 16 byte packets 1 2001:6b8:0:400::282d (2001:6b8:0:400::282d) 302.87 ms 124.232 ms 227.499 ms 2 6gw4.ipv6.tilab.com (2001:6b8:0:120:230:7bff:fe86:e455) 228.415 ms 261.93 ms 134.313 ms 3 gw3-bk1.ipv6.tilab.com (2001:6b8:0:100::4) 347.206 ms 132.78 ms 111.912 ms 4 3ffe:1001:1:f024::2 (3ffe:1001:1:f024::2) 198.316 ms 150.725 ms 133.318 ms 5 if-0-0.charleston.CBQ.TRN.ipv6.ITgate.net (2001:1418:1:101::13) 111.88 ms 110.796 ms 123.694 ms 6 cl-1.trn-01.it.sixxs.net (2001:1418:10:2::2) 111.973 ms 113.056 ms 113.973 ms 7 * * * If possible someone can explain to me where i missed something?
