#265518 — NFS: IPV6

Where can I find information on how to configure NFS to use ipv6 
addresses both server and client.

I haven't found any good information on how to do that and what I did 
find was extremely sparce.

I have NFS mounts working using ipv4 and want to change that to ipv6

Does IPv6 work basically on your machine, including name resolution?

Does it work if you enter the address directly?

How does your fstab look like?

plus FWIW...

https://docs.oracle.com/cd/E23824_01/html/821-1453/ipv6-ref-71.html

"NFS software and Remote Procedure Call (RPC) software support IPv6 in a
seamless manner. Existing commands that are related to NFS services
have not changed. Most RPC applications also run on IPv6 without any
change. Some advanced RPC applications with transport knowledge might
require updates."

According to debian docs NFSServerSetup from the debian wiki

Additionally, rpcbind is not strictly needed by NFSv4 but will be
started as a prerequisite by nfs-server.service. This can be
prevented by masking rpcbind.service and rpcbind.socket.
sudo systemctl mask rpcbind.service
sudo systemctl mask rpcbind.socket

I am going to do that to use NFSv4 only.

I believe that my issue is the in the /etc/exports file but I don't know 
for sure.
I have this in the exports, ipv4 works

/srv/Multimedia 192.168.1.0/24(rw,no_root_squash,subtree_check)
/srv/Other 192.168.1.0/24(rw,no_root_squash,subtree_check)
#/home 2002:474f:e945:0:0:0:0:0/64(rw,no_root_squash,subtree_check)

I am looking for an example

I have commented out the ipv6 for now because I want to use NFSv4 only 
and after I get that working I want to get ipv6 mounts working and 
change the ipv4 mounts to use ipv6.
/srv/Multimedia and /srv/Other are root mounts and there isn't any bind 
mounts

Hello,

This syntax in /etc/exports works for me:

/srv 2001:0db8:a:b::/64(rw,fsid=0)

And then on a client you have to surround the server IP with []
e.g.:

# mount -t nfs4 '[2001:0db8:a:b::1]':/srv /mnt

I have not tested what degree of quoting is required in /etc/fstab,
i.e. may or may not work without the single quotes.

How's your migration away from Debian and all is evils going, by
the way?

Thanks,
Andy

I wouldn't assume Oracle (Solaris?) documentation is authoritative for
Debian systems.  The NFS implementations are probably quite different.

Yes I have bind running and ssh to the host is working

I followed some info that I found on the internet and it didn't work.

I am in the process of re-configuring NFS for V4 only.

I should have that done here shortly and I will try again to mount NFS 
mounts shortly

Could it be there is some misunderstanding?

IPV4 and IPV6 are quite different concepts from NFSv4: I think this
works either on IPV4 and IPV6.
