problem exporting nfs shares

[Antoine]

Hi,
I have the following  /etc/exports

/mnt/a          192.168.1.0/24(rw,no_root_squash,sync)
/mnt/b          192.168.1.0/24(rw,no_root_squash,sync)
/mnt/c          192.168.1.0/24(rw,no_root_squash,sync)
/mnt/d          192.168.1.0/24(rw,no_root_squash,sync)
/mnt/e          192.168.1.0/24(rw,no_root_squash,sync)
/mnt/f          192.168.1.0/24(rw,no_root_squash,sync)

but I can't find out how to see whether they are being exported or not...

I have:
192.168.1.1:/mnt/a /mnt/zs1-4  nfs     rsize=8192,wsize=8192,timeo=14,intr 0 0
192.168.1.1:/mnt/c /mnt/ys7-4  nfs     rsize=8192,wsize=8192,timeo=14,intr 0 0
192.168.1.1:/mnt/b /mnt/xs5-8  nfs     rsize=8192,wsize=8192,timeo=14,intr 0 0
192.168.1.1:/mnt/d /mnt/ws8-4  nfs     rsize=8192,wsize=8192,timeo=14,intr 0 0
192.168.1.1:/mnt/e /mnt/vs9-32  nfs    rsize=8192,wsize=8192,timeo=14,intr 0 0
192.168.1.1:/mnt/f /mnt/us10-4  nfs    rsize=8192,wsize=8192,timeo=14,intr 0 0

in my client fstab and get:
mount to NFS server '192.168.1.1' failed.
RPC Error: 15 ( Program not registered )

for each of the lines when they fail (with mount -av)
I have had a look on the web but can't work out what is going wrong...
Cheers
Antoine
