Hi I am trying to setup a simple IPv6 network with two machines directly connected. I am using linux-2.4.19-stable on these machines. Then I tried to check the connectivity using ping6. When I do normal ping6, it worked in both the directions. When I tried to increase the packet size to something greater than 1500, on one machine I get the replies properly for the all the packets sent. On the other machine, I get the following error: ping: recvmsg: No route to host When ping6 works perfectly fine for small packets, why does it fail for large packets. And why does it fail in only one direction? The interface types I have been using are EtherExpressPro/100 (This is on the machine on which ping6 for large packets is failing) and DECchip Tulip (dc21x4x). Am I missing some configuration or something? Could someone help? regards Madhavi. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
