I'm not pinging?

Shadow Hawkins on Saturday, 18 October 2003 01:38:46

Well, i'm getting them mails, that i dont ping and that my tunnel is down and everything... So i checked the stats, indeed, they stop at wednessday. But my tunnel is up? I haven't firewalled a single thing, i've asked several people to ping6 me, and it all went fine. My host is cl-256.ams-02.nl.sixxs.net / tunnelnumber is 97 Can someone please look into it, and keep the evil robot from threatening me? I do have high latency at the moment, despite the wondershaper :P

Check your routing, and check the forum

My host is cl-256.ams-02.nl.sixxs.net / tunnelnumber is 97

Can someone please look into it, and keep the evil robot from threatening me?

You could have mailed info@sixxs.net, as those are the people who can do dumps and check things. You should have done some tcpdumping and show the icmp packets coming in and going out of your tunnel btw... PING cl-256.ams-02.nl.sixxs.net(cl-256.ams-02.nl.sixxs.net) 56 data bytes --- cl-256.ams-02.nl.sixxs.net ping6 statistics --- 67 packets transmitted, 0 packets received, 100% packet loss Says enought to me :) Let me guess, "upgraded" to 2.4.21 or higher? (That robot has never been wrong btw and mind you: It's good to be evil :)

Whooops, totally missed that, i apologize. I was sorta confused by the fact that other v6 people i know (xs4all connected) could still ping my host, and i could still use the connection. But i've set the route from the other thread ( route -A inet6 del 3ffe:8114:1000::1ff dev lo metric 0) and i'm hoping it's fixed now :) Thanks :) Hope I didn't upset the robot O-)

Hmmm, still not pinging, did what the other thread said. Upgraded to 2.4.22, this is my current v6 routing table: Just disabled the tunnel, to prevent any further creditlos.

3ffe:8114:1000::1fe/128 :: U 0 80 1 lo

3ffe:8114:1000::1ff/128 :: U 0 1378 0 lo

Why do you nullroute the POP endpoint (::1fe)? Which is what is mentioned in the other threads...

Which is why I mentioned the use of 2 /128's which overcomes the removal problem. Also if you read the part about anycast addresses being implemented in 2.4.22 then you would have read that it did that :)
