mount_nfs over IPv6

[diffuser78]

I am trying to nfs mount a directory from a Ubuntu Linux server (its runs a nfs server) on to my client FreeBSD box (running 6.1).


I issue a commands as follows:

mount_nfs -L -r 32768 -w 32768 -t 14 -o noinet4,rw,tcp,intr fe80::21a:a0ff:feb5:7778:/home/daniel/test /mount/test

and I get an error: "tcp6: Netid not found in netconfig database"

If I tweak a little bit as follows:

mount_nfs -L -r 32768 -w 32768 -t 14 -o noinet4,rw,tcp,intr [fe80::21a:a0ff:feb5:7778]:/home/daniel/test /mount/test

I get an error: "zsh: no matches found: [fe80::21a:a0ff:feb5:7778]:/home/daniel/test"

Finally, If I give the interface name as follows:

mount_nfs -L -r 32768 -w 32768 -t 14 -o noinet4,rw,tcp,intr [fe80::21a:a0ff:feb5:7778%eth0]:/home/daniel/test /mount/test

I still get an error: "zsh: no matches found: [fe80::21a:a0ff:feb5:7778]:/home/daniel/test"


What is the correct way of mounting nfs over IPv6. Same host can seamlessly mount on IPv4.

Any insight is greatly appreciated.

thanks,

Hmm... fe80:: is a local, non-routable, IPv6 address. It should work though..

I mount my nfs shares using IPv6, but I've setup name resolving. So the server's name resolves to it's IPv6 address.

Just tried it using the IPv6 IP:

root@williscorto:~#host molly
molly.dicelan.home has address 192.168.1.190
molly.dicelan.home has IPv6 address 2001:888:1c5b::190
root@williscorto:~#mount 2001:888:1c5b::190:/storage storage/
root@williscorto:~#

Works like a charm..

So this IPv6 address (2001:888:1c5b::190 in your case) is not link local address right ? How did you get this address ?

Can you please tell how did you do name resolving, and show how does your /etc/hosts looks like ?

Are you using FreeBSD 7 ? I am currently at 6.1.

Any other suggestions or tips you might want to share ?

Thanks

That's a global IPv6 address. My ISP has (experimental) IPv6 support. If there are no routers between the client and the server you should be able to use the link local addresses.

I've set up a local bind nameserver, I use it to resolve my local domain and as a caching server for Internet.

Currently 7-STABLE but I've used this same setup on 6.
