gets encapsulated.  But all traffic to samba is IPv4, smbd offers
both IPv4 and IPv6 sockets. <br>I just wonder whether this is to be expected? Protocols support IPv4 only,
so why running on IPv6 sockets only for ganesha? Did we configure something
wrong and should completely disable IPv6 on the kernel level<br><br>Any comment is welcome<br><br>Cheers,<br>Heiner<br>-- <br>=======================<br>Heinrich Billich<br>ETH Zürich<br>Informatikdienste<br>Tel.: +41 44 632 72 56<br>heinrich.billich@id.ethz.ch<br>========================<br> <br><br>I did check with<br><br>  ss -l -t -4<br>  ss -l -t  -6<br><br>add  -p to get the process name, too.<br><br>do you get the same results on your ces nodes?<br><br><br>[root@nas22ces04-i config_samples]#   ss -l -t   -4<br>State       Recv-Q Send-Q
