how to mount ipv6 address to linux

Question

I am trying to mount a folder from ubuntu system having ip ipv6 as well as ipv4 address

root@:/home# ifconfig
br0       Link encap:Ethernet  HWaddr 16:37:81:2e:ce:e9  
          inet addr:10.0.3.24  Bcast:10.0.7.255  Mask:255.255.248.0
          inet6 addr: 2001:db8::60fe:5bff:febc:912/64 Scope:Global
          inet6 addr: 2001:db8::e8a6:7d68:16b8:3d86/64 Scope:Global

I can able to ping ipv6 address from different linux system :

[root@Abhitesh home]# ping6 2001:db8::60fe:5bff:febc:912
PING 2001:db8::60fe:5bff:febc:912(2001:db8::60fe:5bff:febc:912) 56 data bytes
64 bytes from 2001:db8::60fe:5bff:febc:912: icmp_seq=1 ttl=64 time=0.968 ms
64 bytes from 2001:db8::60fe:5bff:febc:912: icmp_seq=2 ttl=64 time=1.07 ms

I am getting error, when i am trying to mount with ipv6

[root@Abhitesh home]# mount -t nfs 2001:db8::60fe:5bff:febc:912:/home/abhitesh /home/mount/
mount.nfs: mount system call failed
[root@Abhitesh home]#

with ipv4 mount command is working.

Is that my command is wrong or i need to configure something, to mount with ipv6.

In my system ipv6 is enabled.

cat /proc/sys/net/ipv6/conf/all/disable_ipv6
0

Solution 1

Command is wrong NFS mount command should be

mount -t nfs [2001:db8::60fe:5bff:febc:912]:/home/abhitesh /home/mount/

IPv6 address should be in [].

and for CIFS mount command should be

mount -t cifs -o username=xxxx,password=yyyyy //2001:db8::60fe:5bff:febc:914/public /home/mount

Solution 2

For those who might ever need it, posting below the entries that worked for me. Using Arch linux and link-local IPv6 addresses.

/etc/exports entry on the server

/dir1    fe80::blah:blah:blah:blah(rw,sync,nohide)

/etc/fstab entry on client

[fe80::boom:boom:boom:boom%wlan0]:/dir1    /home/a/b/c    nfs    noatime,noauto,users    0 0

Command when mounting manually

sudo mount [fe80::boom:boom:boom:boom%wlan0]:/dir1 /home/a/b/c
