[gpfsug-discuss] Ganesha all IPv6 sockets - ist this to be expected?

[Wahl, Edward]

I recall looking at this a year or two back.  Ganesha is either v4 and v6 both (ie: the encapsulation you see), OR  ipv4 ONLY.  (ie: /etc/modprobe.d/ipv6.conf   disable=1)

Subject: [gpfsug-discuss] Ganesha all IPv6 sockets - ist this to be expected?


Hello,

I just noted that our ganesha daemons offer IPv6 sockets only, IPv4 traffic gets encapsulated.  But all traffic to samba is IPv4, smbd offers both IPv4 and IPv6 sockets.
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?

Any comment is welcome

Cheers,
Heiner

I did check with

  ss -l -t -4
  ss -l -t  -6

add  -p to get the process name, too.

do you get the same results on your ces nodes?
