mount.nfs: Protocol not supported

Hello.

Used to work since recently, I must be missing something obvious. Client Arch 64b, up-to-date.

I have a little NAS server (arm/debian/BusyBox) which I usually connect to using 'nasup' which aliases in my .bashrc into

'alias nasup='sudo mount 192.168.4.249:/mnt/md1/public /mnt/naspas'

And since this morning, I fall into that 'mount.nfs: Protocol not supported'

I issued:

[jph@1215s ~]$ lsmod|grep nfs
nfsd                  238173  11
auth_rpcgss            31196  1 nfsd
nfs_acl                 2327  1 nfsd
nfs                   127261  0
lockd                  62843  2 nfs,nfsd
sunrpc                187776  21 nfs,nfsd,auth_rpcgss,lockd,nfs_acl
fscache                44574  1 nfs

I've tried different versions:

[jph@1215s ~]$ sudo mount -t nfs 192.168.4.249:/mnt/md1/public /mnt/naspas
mount.nfs: Protocol not supported
[jph@1215s ~]$ sudo mount -t nfs4 192.168.4.249:/mnt/md1/public /mnt/naspas
mount.nfs4: Protocol not supported
[jph@1215s ~]$ sudo mount -t nfs 192.168.4.249:/mnt/md1/public /mnt/naspas -o vers=3
mount.nfs: Protocol not supported

less /etc/nsswitch.conf does looks for files, not something exotic:

# Begin /etc/nsswitch.conf

passwd: files
group: files
shadow: files

publickey: files

hosts: files dns myhostname
networks: files

protocols: files
services: files
ethers: files
rpc: files

netgroup: files

# End /etc/nsswitch.conf

And the damn machine is right there where I expect it:

[root@1215s jph]# showmount -e 192.168.4.249
Export list for 192.168.4.249:
/mnt/md1/public (everyone)

Any idea ?
Don't be afraid to make me feel stupid: I need access to this server.

Re: mount.nfs: Protocol not supported

sudo mount.nfs ... ?

What version of NFS is the server running?

Re: mount.nfs: Protocol not supported

for info (first time I see this)

[root@1215s jph]# ssh root@192.168.4.249
no such identity: /root/.ssh/id_rsa: No such file or directory
no such identity: /root/.ssh/id_dsa: No such file or directory
no such identity: /root/.ssh/id_ecdsa: No such file or directory
root@192.168.4.249's password:

BusyBox v1.00-rc3 (2009.02.19-03:01+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.

NASPAS>

NASPAS> lsmod | grep nfs
NASPAS>

How do I know which version of nfs is the server running? BusyBox is rather limited.

Re: mount.nfs: Protocol not supported

Same problem:
sudo mount.nfs -v  mass:/c/bak /mass
mount.nfs: timeout set for Sat Apr 27 11:59:45 2013
mount.nfs: trying text-based options 'vers=4,addr=192.168.0.80,clientaddr=192.168.0.3'

No problem mounting from same server on OSX machine:

> sudo mount -t nfs -v -overs=3 mass:/c/bak ~/tmp/mass
mass:/c/bak on /Users/<user>/tmp/mass (nfs)
