problem exporting /dev via NFS

raz3k · 03-06-2008, 07:48 AM

Hello, i am using a centos 5.1 i386 distribution on both ends and i want to mount /dev locally using NFS and mount.

I have tried mounting /tmp locally and it worked but mounting /dev gives me the following error:

mount -o ro 81.x.x.x:/dev /mnt/aa
mount: 81.x.x.x:/dev failed, reason given by server: Permission denied

/etc/exports on server:

/dev 82.x.x.x(ro,no_subtree_check)

all services are up and the nfs is working because the /tmp mount i have tested earlier worked.

What shall i try next ?

Thank you!

why would you ever ever ever want to mount /dev over NFS? How would that ever make sense?

because i want to cat /mountpoint/dsp > /dev/dsp

a.k.a. accessing the mic remotely

if you want to spit the raw uncompressed data across a network then you could use something like netcat, but generally that's pretty horrible. you could use something like mpd+icecast to do this "properly".
