If I have an NFS4 server successfully sharing a directory with a client and both machines have valid IPv4 and IPv6 addresses should it be possible to mount the directory using either IPv4 or IPv6? Both machines are running 2.6.34-rc6 kernels, nfs-utils-1.2.2, libtirpc-0.2.0 and rpcbind-0.2.0. Mounting over IPv4 works perfectly, but IPv6 just times out while trying to mount the share. Using tcpdump I see that the two machines exchange 40 packets before the client finally gives up. There are no messages generated in the system log or dmesg of either machine. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
